RESUMO

Structural and biological studies were conducted on the novel complexes [Fe(U)2(H2O)2]Cl3 (FeU) and [Ru(U)2(H2O)2]Cl3 (RuU) (U = 5,6-Diamino-1,3-dimethylpyrimidine-2,4(1H,3H)-dione) to develop an anticancer drug candidate. The two complexes have been synthesized and characterized. Based on our findings, these complexes have octahedral geometry. The DNA-binding study proved that both complexes coordinated with CT-DNA. The docking study confirmed the potency of both complexes in downregulating the topoisomerase I protein through their high binding affinity. Biological studies have established that both complexes can act as potent anticancer agents against three cancer cell lines. RuU or FeU complexes induce apoptosis in breast cancer cells by increasing caspase9 protein and inhibiting proliferating cell nuclear antigen (PCNA) activity. In addition, both complexes down-regulate topoisomerase I expression in breast cancer cells. Therefore, the RuU and FeU complexes' anticancer activities were mediated via both apoptosis induction and topoisomerase I down-regulation. In conclusion, both complexes have dual anticancer activity pathways that may be responsible for the selective cytotoxicity of the complexes. This makes them more suitable for the development of novel cancer treatment strategies.

RESUMO

The liver is the most important organ in the body. Hepatocyte oxidative damage occurs to excess ROS. Liver fibrosis is a mechanism that the immune system uses to treat extreme inflammation by repairing damaged tissue with the creation of a scar. The outcome of fibrosis may be reversed by consuming natural plant extracts with high ROS-scavenging ability. The date palm fruits contain caffeic acid, gallic acid, syringic acid, and ferulic acid, which have anti-inflammatory, antioxidant, and hepatoprotective properties. This study aimed to prepare a date fruit extract, load it onto chitosan nanoparticles, and compare its anti-fibrotic activity with the unloaded crude extract in the CCl4-mouse model. Our findings show that nanocomposite (Cs@FA/DEx) has anti-fibrotic properties and can improve liver function enzymes and endogenous antioxidant enzymes by inhibiting cell apoptosis caused by CCl4-induction in mice. Furthermore, significantly reduced CD95 and ICAM1 levels and down-regulation of TGFß-1 and collagen-α-1 expression demonstrated the anti-fibrotic effects of the Cs@FA/DEx. Therefore, the Cs@FA/DEx might be an innovative supplement for inhibiting liver fibrosis and hepatocyte inflammation induced by chemical toxins. Besides, this nano-supplement could be a promising anti-hepatocellular carcinoma agent as it has potent in vitro anticancer activity against the HePG2 cell line.

RESUMO

Lung cancer progresses without obvious symptoms and is detected in most patients at late stages, causing a high rate of mortality. Avocado peels (AVP) were thought to be biowaste, but they have antioxidant and anticancer properties in vitro. Chitosan nanoparticles (Cs-NPs) were loaded with various plant extracts, increasing their in vitro and in vivo anticancer activities. Our goal was to load AVP onto Cs-NPs and determine the role of AVP-extract or AVP-loaded Cs-NPs in controlling the progression of lung cancer caused by urethane toxicity. The AVP-loaded chitosan nano-combination (Cs@AVP NC) was synthesized and characterized. Our in vitro results show that Cs@AVP NC has higher anticancer activity than AVP against three human cancer cell lines. The in vivo study proved the activation of apoptosis in lung cancer cells with the Cs@AVP NC oral treatment more than the AVP treatment. Additionally, Cs@AVP NC-treated animals showed significantly higher p53 and Bax-expression levels and lower NF-κB p65 levels in their lung tissues than in positive control animals. In conclusion, our study demonstrated the superior anticancer potency of Cs@AVP NC over AVP extract and its ability to inhibit lung cancer proliferation. Therefore, oral consumption of Cs@AVP NC might be a promising treatment for lung cancer.

RESUMO

Methotrexate (MXT) is a medication used for cancer and rheumatoid treatment with severe organs toxicity as a side effect. Paullinia cupana (Guarana) is a plant with pleiotropic functions used to overcome the side effects of some chemotherapeutic medications. Current study aimed to examine the possible protective effect of guarana against oxidative stress induced by a single dose of MTX in testis. Forty male mice were divided into 4 groups (8 weeks old; 30 g weight), 1st group is negative control. The 2nd group is positive intoxicated group, received a single dose of MTX intraperitoneally (IP; 20 mg/kg BW in saline) on day 7. The 3rd group received guarana seed extract orally (300 mg/kg BW daily) for 12 days. The protective group was given guarana seed extract orally for 1 week, then on day 7 injected with MTX, and continued with guarana for extra 5 days. Blood was taken for biochemical measurement (hormones, antioxidants, cytokines, and oxidative stress biomarkers). Testicular tissues were taken for gene quantification (qRT-PCR), testicular oxidative stress activity (malondialdehyde; MDA, and SOD) and comet assay (sperm DNA damage), and histopathological changes at the end of experimental design. MTX intoxication caused a decrease in testicular SOD, GSH, and catalase and an increase in serum and tissue levels of MDA. Biomarkers of oxidative stress were increased by MTX intoxication, and were ameliorated by guarana administration to MTX-intoxicated mice. Guarana prevented the increase in IL-1ß and IL-6 levels compared to mice intoxicated with MTX alone. MTX upregulated the expression of caspase-3 and downregulated Bcl-2 expression using qRT-PCR analysis. These negative impacts of MTX were protected by guarana pre-administration. MTX decreased reproductive hormones and altered spermogram parameters (sperm concentration and motility, and percentage of live and dead sperms). In addition, the mRNA expression of steroidogenesis-associated genes, such cytochrome P450 cholesterol side-chain cleavage enzyme (P450scc), and 17ß hydroxyl steroid dehydrogenase (17ß-HSD) was downregulated in the MTX-treated group, all were prevented by guarana administration. The sperm DNA damage revealed by a comet assay was increased in MTX group and was reversed to control levels by guarana supplementation. Finally, testis histology of MTX-group showed marked spermatocytes vacuolization and a decrease in spermatogenesis. Guarana administration abrogated histopathological changes reported in the Leydig cells and testicular tissues. In conclusion, guarana has the potential as a supplement medication to antagonize testicular oxidative stress induced by methotrexate.

RESUMO

Objective: Resveratrol is a polyphenolic compound that possesses strong antioxidant and anti-inflammatory activities. This study evaluated the effects of resveratrol on oxidative stress, fibrosis and multiple genes regulation in the kidneys of high fat (HF) diet-fed rats. Methods: Wistar rats were fed with HF diet for eight weeks. These rats were also treated with resveratrol for eight weeks. Finally, kidney tissue samples were isolated from all sacrificed rats. The histological changes, creatinine and uric acid levels, oxidative stress parameters such as malondialdehyde (MDA), nitric oxide, and advanced oxidation protein product (AOPP) levels were analyzed. The antioxidant enzymes such as catalase, superoxide dismutase (SOD) activities and reduced glutathione (GSH) levels; gene expression of inflammatory and fibrosis-related genes namely, inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), transforming growth factor beta1 (TGF-ß1), and collagen-1 were assessed. Moreover, gene expression of oxidative stress-related genes such as nuclear factor erythroid 2-related factor 2 (Nrf-2), SOD, catalase, and glutathione reductase, were also assessed. Results: HF diet-fed rats showed increased creatinine and uric acid levels in plasma which were lowered by resveratrol treatment. The study findings also revealed that resveratrol counterbalanced the oxidative stress and prevented the expression of the inflammatory genes; restored the catalase and SOD activities followed by the up-regulation of antioxidant genes expression in the kidneys of HF diet-fed rats. HF diet caused the Nrf-2 down-regulation followed by the decreased expression of HO-1 and HO-2 genes, which was restored by resveratrol treatment. Moreover, the histological assessment showed lipotoxicity and increased fibrosis in the kidneys of HF diet-fed rats. Resveratrol prevented the kidney fibrosis probably by limiting oxidative stress, inflammation, and down-regulating TGF-ß1 mediated signaling pathway. Conclusion: In conclusion, resveratrol treatment showed beneficial effects in preventing oxidative stress and fibrosis in the kidneys of HF diet-fed rats probably by modulating the gene expression of oxidative stress and inflammation related factors and enzymes.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) has become one of the public health problems globally. The occurrence of NAFLD is usually accompanied by a series of chronic metabolic diseases, with a prevalence rate is 25.24% among adults worldwide. Therefore, NAFLD seriously affects the quality of life in patients and causes a large economic burden. It has been reported that puerarin has the function of lowering the serum lipids, but due to the complexity of NAFLD, the specific mechanism of action has not been clarified. The aim of this study was to evaluate the preventive or ameliorating effects of two doses of puerarin (0.11% and 0.22% in diet) on high-fat and high-fructose diet (HFFD)-induced NAFLD in rats. The rats were fed with HFFD-mixed puerarin for 20 weeks. The results showed that puerarin ameliorated the levels of lipids in the serum and liver. Further exploration of the mechanism found that puerarin ameliorated hepatic lipid accumulation in NAFLD rats by reducing the expression of Srebf1, Chrebp, Acaca, Scd1, Fasn, Acacb, Cd36, Fatp5, Degs1, Plin2, and Apob100 and upregulating the expression of Mttp, Cpt1a, and Pnpla2. At the same time, after administration of puerarin, the levels of antioxidant markers (superoxide dismutase, glutathione peroxidase, and catalase) were significantly increased in the serum and liver, and the contents of serum and hepatic inflammatory factors (interleukin-18, interleukins-1ß, and tumor necrosis factor α) were clearly decreased. In addition, puerarin could ameliorate the liver function. Overall, puerarin ameliorated HFFD-induced NAFLD by modulating liver lipid accumulation, liver function, oxidative stress, and inflammation.

RESUMO

A novel series of amides based TMP moiety was designed, synthesized and evaluated for their antiproliferative as well as enzyme inhibition activity. Compounds 6a and 6b showed remarkable cytotoxic activity against HepG2 cells with IC50 values 0.65 and 0.92 µM, respectively compared with SAHA and CA-4 as reference compounds. In addition, compound 6a demonstrated good HDAC-tubulin dual inhibition activity as it showed better HDAC activity as well as anti-tubulin activity. Moreover, compound 6a exhibited G2/M phase arrest and pre-G1 apoptosis as demonstrated by cell cycle analysis and Annexin V assays. Further apoptosis studies demonstrated that compound 6a boosted the level of caspase 3/7. Caspase 3/7 activation and apoptosis induction were evidenced by decrease in mitochondrial permeability suggesting that activation of caspase 3/7 may occur via mitochondrial apoptotic pathway.

RESUMO

The main objective of this study was to evaluate the effect of chamomile oil (Ch), grape seed oil (GS), their mixture and antibiotic (colistin) (AN) as feed addetives on the productivity of growing rabbits as well as in vitro study to evaluate the antimicrobial activity of both Ch and GS oils. To achive this objective, a total of 96 New Zealand (NZW) weaned rabbits, 5 weeks-old were randomly allotted into eight groups. Rabbits were kept under observation for eight weeks and the trial ended at thirteen weeks-old. The experimental treatments were: 1) Basal diet (BD); 2) BD + antibiotic; 3) BD + 0.5 ml GS/ kg diet; 4) BD + 1.0 ml GS/ kg diet; 5) BD + 1.5 ml GS/ kg diet; 6) BD + 0.5 ml Ch/ kg diet; 7) BD + 1.0 ml Ch/ kg diet and 8) BD + 1.5 Ch/ kg diet. Live body weight (LBW) was markedly elevated (p < 0.05) in groups fed on ration included feed additives compared with the control at weeks 9 and 13 of age. Cumulative body weight gain (BWG) and feed intake (FI) increased (p < 0.05) throughout 5-9 and 5-13 weeks of age in rabbits fed rations plus the studied additives. Feed conversion ratio (FCR) was insignificantly altered by dietary feed additives. Spleen and intestine relative weights reduced (p < 0.05) in groups treated with different studied additives. In view of the experiment finings, it could be concluded that dietary supplementation of GS and Ch have a positive impact on the productivity of growing rabbits than that of the control and antibiotic-treated groups.

RESUMO

This study aimed to investigate the oxidative neurotoxicity induced by silver nanoparticles (AgNPs) and assess the neuroprotective effects of quercetin against this toxicity. Forty adult male rats were divided into four equal groups: control, AgNPs (50 mg/kg intraperitoneally), quercetin (50 mg/kg orally), and quercetin + AgNPs. After 30 days, blood and brain tissue samples were collected for further studies. AgNP exposure increased lipid peroxidation and decreased glutathione peroxidase, catalase, and superoxide dismutase activities in brain tissue. AgNPs decreased serum acetylcholine esterase activity and γ-aminobutyric acid concentrations. AgNPs upregulated tumor necrosis factor-α, interleukin-1ß, and Bax transcript levels. AgNPs reduced the transcripts of claudin-5, brain-derived neurotrophic factor, paraoxonase, nuclear factor-erythroid factor 2 (Nrf2), and Bcl-2. Histopathologically, AgNPs caused various degenerative changes and neuronal necrosis associated with glial cell reactions. AgNPs increased the immunohistochemical staining of glial fibrillary acidic protein (GFAP) in the cerebrum and cerebellum. Oral treatment with quercetin efficiently counteracted the opposing effects of AgNPs on brain tissue via modulation of tight junction proteins, Nrf2, and paraoxonase, and its positive mechanism in modulating pro-inflammatory cytokines and the downregulation of GFAP expression, and the apoptotic pathway. AgNPs also altered the severity of histopathological lesions and modulated GFAP immunostaining in the examined tissue.

RESUMO

GA3 is widely used as a growth stimulant in agricultural regions. The long-term use of GA3 can cause organs damage. Chrysin is a flavonoid found in nature that is commonly used to treat organ toxicity. In this study, we examined the effect of chrysin on the testes function of GA3-affected rats. A total of 24 male Wistar rats were divided into 4 groups. Saline was given to the control group. The chrysin group was given orally 50 mg/kg/BW of chrysin in saline. The GA3 group received a daily oral gavage of GA3 (55 mg/kg/BW). The protective group (chrysin + GA3) was given chrysin and GA3 as those described in chrysin and GA3 groups. There were an increase in MDA levels in the serum and testicular tissue of GA3-treated group. Catalase, GSH, and SOD levels were all lowered in the GA3-treated rats. Chrysin dramatically reduced the harmful effects of GA3 by restoring reproductive hormone levels, altered sperm parameters, and antioxidant capabilities. Furthermore, GA3 reduced the quantitative expression of steroidogenesis genes StAR and 3-HSD, as well as Bcl2 genes, while it increased the apoptotic marker BAX; all were alleviated by the pre-administration of chrysin. The pre-administration of chrysin protected the GA3 group from spermatogenic vacuolation, interstitial edema, necrosis, and depletion. Chrysin inhibited oxidative stress and modulated antioxidant activity, as well as apoptosis-/anti-apoptosis-related mediators in the testes. Chrysin has the potential to repair GA3-induced testicular dysfunctions. This suggests that chrysin is preferable as a medication to mitigate GA3-induced oxidative damage in the testes. PRACTICAL APPLICATIONS: Chrysin has the potential to repair GA3-induced testicular dysfunctions. This suggests that chrysin is preferable as a medication to mitigate GA3-induced oxidative damage in the testes.

RESUMO

Gibberellic acid (GA3), a widely known plant growth regulator, has been mostly used in agriculture. Little is known regarding its toxicity or the impact of its metabolic mechanism on human health. The current study examined the protective impact of chrysin against GA3-induced liver and kidney dysfunctions at biochemical, molecular, and histopathological levels. Forty male albino rats were allocated into 4 groups. The control group received saline; the chrysin group received 50 mg/kg/BW orally daily for 4 weeks; the GA3 group received 55 mg/kg/BW GA3 via daily oral gavage for 4 weeks, and the protective group (chrysin + GA3) was administered both chrysin and GA3 at the same dosage given in chrysin and GA3 groups. Chrysin was administered 1 h earlier than GA3. The GA3 induced liver and kidney injuries as proven by the elevation of hepatic and renal markers with a significant increase in malondialdehyde levels. Furthermore, a decrease of catalase and glutathione was reported in the GA3-administered rats. Pre-administration of chrysin significantly protected the hepatorenal tissue against the deleterious effects of GA3. Chrysin restored the hepatorenal functions and their antioxidant ability to normal levels. Moreover, chrysin modulated the hepatorenal toxic effects of GA3 at the molecular level via the upregulation of the antiapoptotic genes, interleukin-10 (IL-10), hemoxygenase-1, and nuclear factor erythroid 2-related factor 2 expressions; the downregulation of the kidney injury molecule-1 and caspase-3 mRNA expressions; and a decrease in IL-1ß and tumor necrosis factor-α secretions. Additionally, the pre-administration of chrysin effectively attenuated the GA3-induced hepatorenal histopathological changes by regulating the immunoexpression of cytochrome P450 2E1 (CYP2E1) and pregnane X receptor, resulting in normal values at the cellular level. In conclusion, chrysin attenuated GA3-induced oxidative hepatorenal injury by inhibiting free-radical production and cytokine expression as well as by modulating the antioxidant, apoptotic, and antiapoptotic activities. Chrysin is a potent hepatorenal protective agent to antagonize oxidative stress induced by GA3.

RESUMO

Diabetes is a worldwide public health disease. Currently, the most effective way to treat diabetes is to mitigate postprandial hyperglycemia by inhibiting carbohydrate hydrolysis enzymes in the digestive system. Plant extracts are rich in bioactive compounds, which can be used in diabetes treatment. This study aims to evaluate the polyphenols content in ethanolic extracts of avocado fruit and leaves (Persea americana Mill.). Additionally, their antioxidant activity using DPPH, while the inhibition ability of α-amylase was examined by reacting different amounts of the extracts with α-amylase compared to acarbose as standard inhibitor. The active compounds were detected in the extracts by LC/MS. The obtained results showed that the leaf extract recorded a significant content of total phenolic compounds compared to the fruit extract (178.95 and 145.7 mg GAE /g dry weight, respectively). The total flavonoid values ​​ranged from 32.5 to 70.08 mg QE/g dry weight of fruit and leaves extracts, respectively. Twenty-six phytogenic compounds were detected in leaf and fruit extract by LC/MS. These compounds belong to fatty acids, sterols, triterpenes, phenolic acids, and flavonoids. The antioxidant activity of the extracts is due to the exist of phytogenic compounds, i.e., polyphenols and flavonoids. The antioxidant activity increased in a concentration dependant manner. Avocado fruit extract (1000 µg/mL) scavenged 95% of DPPH while leaf extract rummaged 91.03% of free radicals compared with Vit C and BHT. Additionally, higher α-amylase inhibitory activity was observed in fruit extract than the leaf extract, where the fruit and leaf extract (1000 µg/ml) inhibited the enzyme by 92.13% and 88.95%, respectively. The obtained results showed that the ethanolic extracts of avocado could have a significant impact on human health due to their high content of polyphenols.

RESUMO

Breast cancer is a major cause of death in women worldwide. In this study, 60 female rats were classified into 6 groups; negative control, α-aminophosphonates, arylidine derivatives of 3-acetyl-1-aminoquinolin-2(1H)-one, DMBA, DMBA & α-aminophosphonates, and DMBA & arylidine derivatives of 3-acetyl-1-aminoquinolin-2(1H)-one. New α-aminophosphonates and arylidine derivatives of 3-acetyl-1-aminoquinolin-2(1H)-one were synthesized and elucidated by different spectroscopic and elemental analysis. Histopathological examination showed marked proliferation of cancer cells in the DMBA group. Treatment with α-aminophosphonates mainly decreased tumor mass. Bcl2 expression increased in DMBA-administered rats and then declined in the treated groups, mostly with α-aminophosphonates. The level of CA15-3 markedly declined in DMBA groups treated with α-aminophosphonates and arylidine derivatives of 3-acetyl-1-aminoquinolin-2(1H)-one. Gene expression of GST-P, PCNA, PDK, and PIK3CA decreased in the DMBA group treated with α-aminophosphonates and arylidine derivatives of 3-acetyl-1-aminoquinolin-2(1H)-one, whereas PIK3R1 and BAX increased in the DMBA group treated with α-aminophosphonates and arylidine derivatives of 3-acetyl-1-aminoquinolin-2(1H)-one. The molecular docking postulated that the investigated compounds can inhibt the Thymidylate synthase TM due to high hydrophobicity charachter.

RESUMO

The widespread industrial use of nitrite in preservatives, colorants, and manufacturing rubber products and dyes increases the possibilities of organ toxicity. Lithium borate (LB) is known as an antioxidant and an oxidative stress reliever. Therefore, this study is aimed at examining the effect of LB on nitrite-induced hepatorenal dysfunction. Twenty-eight male Swiss mice were divided into four equal groups. Group 1, the control group, received saline. Group 2 received LB orally for 5 consecutive days at a dose of 15 mg/kg bw. Group 3, the nitrite group, received sodium nitrite (NaNO2) on Day 5 (60 mg/kg bw intraperitoneally). Group 4, the protective group (LB + NaNO2 group), received LB for 5 days and then a single dose of NaNO2 intraperitoneally on Day 5, the same as in Groups 2 and 3, respectively. Samples of blood and kidney were taken for serum analysis of hepatorenal biomarkers, levels of antioxidants and cytokines, and the expression of genes associated with oxidative stress and inflammation. NaNO2 intoxication increased markers of liver and kidney functions yet decreased reduced glutathione (GSH), superoxide dismutase (SOD), and catalase activities in blood. NaNO2 also increased the expression of tumor necrosis factor (TNF-α), interleukin-1ß and interleukin-6 (IL-1ß and IL-6). Pre-administration of LB protected mice from oxidative stress, lipid peroxidation, and the decrease in antioxidant enzyme activity. Moreover, LB protected mice from cytokine changes, which remained within normal levels. LB ameliorated the changes induced by NaNO2 on the mRNA of nuclear factor erythroid 2-related factor 2 (Nfr2), heme oxygenase-1 (HO-1), nuclear factor-kappa B (NF-κB), transforming growth factor-beta 2 (TGF-ß2), and glutathione-S-transferase (GST) as determined using quantitative real-time PCR (qRT-PCR). These results collectively demonstrate that LB ameliorated NaNO2-induced oxidative stress by controlling the oxidative stress biomarkers and the oxidant/antioxidant state through the involvement of the Nrf2/HO-1 and NF-κB signaling pathways.

RESUMO

BACKGROUND: Gentamicin (GM) is a low-cost, low-resistance antibiotic commonly used to treat gram-negative bacterial diseases. Cisplatin (Csp) is a platinum-derived anti-neoplastic agent. This experiment aimed to identify the early signs of gentamicin and cisplatin-induced nephrotoxicity in rats. Thirty Wistar rats were divided into three groups of 10: a control group, which received no treatment; a gentamicin group administered by a dose of (100 mg/kg, IP) for 7 consecutive days, and a cisplatin group was administered intraperitoneal in a dose of (1.5 mg/kg body weight) repeated twice a week for 3 weeks. RESULTS: Both experimental groups exhibited increased levels of creatinine, urea, and uric acid, with the cisplatin-treated group showing higher levels than the gentamicin group. Experimental groups also exhibited significantly increased Malondialdehyde (MDA), reduced glutathione (GSH), and glutathione peroxidase (GSH-Px) with more pronounced effects in the cisplatin-treated group. Further, both experimental groups exhibited significant up-regulation of Tumor Necrosis Factor α (TNF-α), caspase-3, and Bax and down regulation of Bcl-2. CONCLUSION: These findings confirm the use of necrotic, apoptotic genes as early biomarkers in the detection of tubular kidney damage. Further, cisplatin was shown to have a greater nephrotoxic effect than gentamicin; therefore, its use should be constrained accordingly when co-administered with gentamicin.

RESUMO

The current study aims to investigate the anticancer potential of Periploca hydaspidis extracts against HCCLM3 and MDA-MB 231 cell lines with invasive properties and to identify molecular targets underlying its action mechanism. Cytotoxic screening of plant extracts was done via MTT assay against liver and breast cancer cell lines and GC/MS of the best cytotoxic fraction was performed to identify its chemical composition. Flow cytometry detected apoptosis and cell-cycle changes after drug treatment. The specified cells were studied for migration and invasion potential along with performing western blot analysis of proteins involved in apoptosis, cell-cycle, metastasis, and MAPK (Mitogen-activated protein kinase) cell-signaling pathway. The results revealed the crude methanol (PHM) fraction of P. hydaspidis shown dose and time dependent cell-proliferative inhibition response. GC/MS analysis detected 54 compounds of which fatty acids (29.8%), benzenoids (15.7%), and esters (14.3%) constituted the bulk. The inhibitory effect against cancer cells was linked with cell-cycle arrest at G0/G1 phase, induction of apoptosis, reduced migration and invasion capabilities post treatment. PHM induced apoptosis via downregulation of anti-apoptotic (survivin, B-cell lymphoma Extra-large; BCL-XL, X-linked inhibitor of apoptosis protein; XIAP, Myelocytomatosis; C-myc), metastatic (Matrix metallopeptidases 9/2; MMP9/2), and cell-cycle regulatory (cyclin D1 and E) proteins, whereas upregulation of pro-apoptotic proteins (Bcl-2 homologous antagonist/killer; BAK, Bcl-2-Associate X protein; BAX, cleaved caspases; 3,7,8,9, and PARP) and activation of MAPK (Jun amino-terminal kinase; JNK and P38) pathway. P38 was needed for PHM-induced apoptosis, where the inhibition of P38 by pharmacological inhibitor (SB239063) diminished the apoptotic effects. Overall, our results conclude that PHM can inhibit cell-proliferation and induce apoptotic effects by activation of P38 MAPK cell-signaling pathway. This suggests the methanol fraction of P. hydaspidis (PHM) to have anticancer compounds, potentially useful for treating liver and breast cancer. In future, one-step advance studies of PHM regarding its role in metastatic inhibition, immune response modulation for reducing tumor, and inducing apoptosis in suitable animal models would be an interesting and promising research area.

RESUMO

Reproductive drugs that include contraceptive and fertility drugs are used to manage reproductive health in both humans and animals. Contraceptive drugs are mainly used by humans for reversible contraception whereas fertility drugs are mainly used in animals to increase milk production, poultry products and meat production. Usage of these drugs has increased manifold in the last decade. These drugs are excreted through body fluids (mainly urine and milk) that lead to contamination of surface water, milk and animal produce. Consumption of such contaminated products or water results in reproductive disorders and different types of cancers in humans. This questionnaire-based study was designed and conducted involving gynecologists, pharmacies, medical stores and veterinarians in Patiala city and its adjoining areas in India to evaluate the quantitative and qualitative aspects of use of these drugs. A total of 150 survey points were identified with random sampling method. Data was analyzed using appropriate statistical tools. The results showed that contraceptive drugs constitute 86% of reproductive drugs usage in humans. Further, steroidal contraceptives constitute a huge 94.7% share of contraceptive drugs, and of these combined oral contraceptives have 79.79% share among which a combination is ethinylestradiol and levonorgestrel is the most popular (20.92%). The consumption of COCs is higher than that of progestin only pills (Z = 3.39) as well as estrogen only pills (Z = 4.30). In contrast, usage of non-hormonal fertility drugs (89%) dominates over the hormonal class (11%) in humans. The most widely used non-hormonal fertility drug is clomiphene citrate (73.87%). In animals, the prescription rate of hormonal fertility drugs is higher (83%) than the non-hormonal one, where in the most widely prescribed drug is buserelin acetate. These findings are in consonance with the similar studies carried out in US, Europe and Canada which suggest that reproductive drugs usage pattern is more or less similar across the globe. A careful control to discourage indiscriminate use of such drugs is the need of hour to prevent damage of environment and ultimately to the health of living beings.

RESUMO

The extensive usage of gibberellic acid (GA3) in agriculture and plant growth is generally associated with enormous human and public health hazards. The present research assesses the impact of n-acetyl cysteine (NAC) on the hepatorenal injury persuaded by GA3 for this purpose, After two weeks of adaptation twenty-four rats allocated into four groups (6 rats/group) as follows: control group, supplied with saline only; n-acetyl cysteine (NAC) group, provided with 150 mg/kg/bw by stomach tube (orally) dissolved in saline; Positive GA3 group, received GA3 (55 mg/kg/bw) orally; Protective group received NAC (150 mg/kg/bw) and GA3 (55 mg/kg/bw) as in NAC and GA3 groups. Rats received their treatments for consecutive 3 weeks. On day 22, rats were anesthetized, then euthanized. Blood and tissue samples were obtained for biochemical, antioxidants markers analysis, gene expression, and histopathological examination. Our results revealed significant changes in serum AST, ALT, urea, uric acid, total protein, and albumin levels with a substantial rise of MDA and NO concentration in GA3 treated rats along with a considerable decrease of the GSH and overexpression of the inflammatory hepatic and renal cytokines (IL-10, TNF-α, NOS) and fibrotic gene expression TGF-ß1, and α-SMA, with boost expression of nuclear factor-kappa (NFk B). NAC co-administered with GA3 significantly normalized the kidney and liver function and the antioxidant state, besides normal histological structure of both liver and kidney tissue and downregulated expression of the pro-inflammatory cytokines as well as, fibrogenic gene expression. PRACTICAL APPLICATIONS: The current study confirmed that GA3 induced hepto-renal dysfunction that was ameliorated by NAC administration. Moreover, our findings confirmed the antioxidant capability of n-acetyl cysteine and afford robust evidence about the ameliorative effect of the n-acetyl cysteine to attenuate the hepatorenal injury induced by gibberellic acid through modulation of the antioxidant defense system fibrogenic, and pro-inflammatory cytokines expression.

RESUMO

In agriculture, gibberellic acid (GA3) is commonly used with extreme dangers for public health. The current research evaluates the improving effects of n-acetyl cysteine (NAC, 150 mg/kg bw) co-administered with GA3 (55 mg/kg bw) mediated testicular injury. Twenty-four male albino rats were split into 4 groups: Negative control (CNT), NAC group, positive GA3 group and protective group, co-administered NAC plus GA3. On day 21, rats were anesthetised then euthanised by decapitation. Blood samples were collected; testicular samples were taken for semen analysis, serum chemistry, RNA extraction, histological and antioxidants markers examination. Our results revealed a significant decline p < .05 of catalase level and total antioxidant capacity. There was a substantial rise of MDA concentration in GA3-treated rats along with a considerable decrease of the antioxidant markers (SOD, GSH) and serum male reproductive hormones. In GA3-treated rats, an overexpression of the inflammatory cytokines (TNF-α, IL-1ß) and anti-inflammatory cytokine IL-10 with boost mRNA expression of nuclear factor-kappa (NFk B) were confirmed. There was downregulation of steroidogenesis genes and decrease in sperm quality and concentration with an increase in sperm abnormalities, all were reported in GA3-treated rats. NAC treatment significantly increased the antioxidant state, testicular function beside structural germ cell and seminiferous tubules histology accompanied by upsurge of steroidogenic mRNA expressions (P450scc and 3ß-HSD) and downregulated the pro-inflammatory cytokines mRNA expression (TNF-α, IL-1ß). These results confirm the antioxidant capability of NAC and afford robust evidence about the ameliorative effect of the NAC to attenuate the testicular injury induced by GA3 through modulation of the antioxidant defence system, steroidogenic and pro-inflammatory cytokines mRNA expression.

RESUMO

Salsola imbricata is a herbal plant native to Saudi Arabia, known for its antioxidative and anti-inflammatory properties. This study explored the protective effects of an ethanolic leaf extract of Salsola imbricata against the oxidative stress and hepatic injury caused by acrylamide. Rats received intragastric administrations of 20 mg/kg of body weight of acrylamide to induce hepatic injury, or 300 mg/kg of body weight of Salsola ethanolic extract orally for 7 days before acrylamide administration. The treatments were continued for 3 weeks. Blood and liver samples were collected from all the groups, and the following biochemical parameters were tested: serum ALT (alanine aminotransferase), AST (aspartate aminotransferase), GGT (gamma glutaryl transferase), urea, albumin, total proteins, catalase, SOD (superoxide dismutase), reduced glutathione (GSH), nitric oxide (NO), and MDA (malondialdehyde). Quantitative real-time PCR (qRT-PCR) was used to examine the expression of Nrf2 (Nuclear factor-erythroid factor 2-related factor 2), HO-1 (Hemoxygenase-1), COX-2 (Cyclooxgenase-2), TGF-ß1 (transforming growth factor-beta1), Bax, and Bcl2 (B-cell lymphoma 2), which are associated with oxidative stress, fibrosis, apoptosis, and anti-apoptotic effects. The annexin and survivin immunoreactivity were examined at the immunohistochemical level. Pretreatment with the Salsola ethanolic extract reduced the negative impact of acrylamide on ALT, AST, GGT, urea, albumin, and total proteins. The Salsola ethanolic extract reversed acrylamide's effects on serum and tissue antioxidants. Nrf2/HO-1 expression was downregulated, while COX-2 and TGF-ß1 were upregulated in the acrylamide-administered group and normalized by the pre-administration of Salsola ethanolic extract to the acrylamide experimental group. The immunoreactivity of annexin and survivin was restored in the experimental group administered Salsola ethanolic extract plus acrylamide. In conclusion, Salsola ethanolic extract inhibits and regulates the side effects induced in the liver by acrylamide. Salsola induced its impacts by regulating inflammation, oxidative stress, and apoptosis-/anti-apoptosis-associated genes at the biochemical, molecular, and cellular levels. Salsola is recommended as oxidative stress relievers against environmental toixicity at high altitude areas.
