RESUMO

Ginger (Gin) has numerous therapeutic properties. One of Gin's most potent components is 6-gingerol, a naturally occurring phenol. This study aimed to investigate the therapeutic impact of gingerol and/or sorafenib on the ATG4/CASP3 and COIIV/COX-2/NF-B Expression as a potential therapy for DAB-induced HCC. Gin was administered to HCC mice induced by p-Dimethylaminoazobenzene (DAB) alone or combined with sorafenib (Sor). Superoxide dismutase (SOD), catalase (CAT), and oxidative stress malondialdehyde (MDA), as well as biochemical markers including AST, ALT, ALP, Albumin, and Bilirubin, were examined. The expression of oncogenes (COIIV, COX-2, NF-κB, and survivin) and tumor suppressor genes (ATG4 and CASP3) was evaluated using qPCR. According to the results, the levels of MDA have been markedly decreased, while SOD and CAT have been increased. Further, the expression levels of tumor suppressor genes were upregulated, whereas the expression levels of oncogene genes were downregulated. Furthermore, in a dose-dependent manner, gingerol has shown the potential to alleviate hepatic portal vein (PV) dilatation and could offer a reliable therapy for HCC. This suggests combining the two compounds may be more effective than alone and that Gin could be a promising therapeutic option for HCC. The binding of Gin and Sor to the active sites of the target genes prevents them from functioning normally, which in turn stops the pathways from carrying out their oncogenic functions. Additionally, COX-2 inhibition reduces the production of certain pro-inflammatory compounds, which further averts oncogenesis. Conclusively, this study indicated that Gin has cytoprotective properties and anti-cancer activity that may be related to controlling oxidative stress. This effect may be achieved by suppressing the COIIV/COX-2/NF-κB pathway and upregulating the ATG4 /CASP3 pathways.

RESUMO

Hepatocellular carcinoma (HCC) is a serious and potentially fatal form of cancer associated with liver damage. New anticancer drugs are increasingly needed due to the increasing number of cancer cases every year. In this study, diarylheptanoids (DAH) from Alpinia officinarum were examined for their antitumor activity against DAB-induced HCC in mice, as well as their ability to reduce liver damage. Assays for cytotoxicity were conducted using MTT. The DAB-induced HCC Swiss albino male mice were given DAH and sorafenib (SOR) either as single treatments or in combination, and the effects on tumour development and progression were monitored. Malondialdehyde (MDA) and total superoxide dismutase (T-SOD) were evaluated along with biomarkers of liver enzymes (AST, ALT, and GGT). The apoptosis-related gene (CASP8), the apoptosis-related gene (p53), the anti-inflammatory genes (IL-6), the migration-related gene matrix metalloprotease-9 (MMP9), and the angiogenesis-related gene vascular endothelial growth factor (VEGF) were assessed using qRT-PCR in the hepatic tissue. As a final step, DAH and SOR were docked with CASP8 and MMP9 via molecular docking to propose potential mechanisms of action. Our results revealed that the combination of DAH and SOR has a potent inhibitory effect on the growth and viability of the HepG2 cell line. The outcomes demonstrated that DAH and SOR-treated HCC-bearing mice displayed a reduction in the tumour burden and liver damage as demonstrated by (1) parameters of repaired liver function; (2) low levels of hepatic MDA; (3) elevated levels of hepatic T-SOD; (4) p53, IL-6, CASP8, MMP9, and VEGF downregulation; and (5) enhanced hepatic structure. The best results were revealed in mice that were co-treated with DAH (given orally) and SOR (given intraperitoneally). The docking study also proposed that both DAH and SOR could inhibit CASP8 and MMP9's oncogenic activities and had a high affinity for these enzymes. In conclusion, according to study findings, DAH enhances SOR antiproliferative and cytotoxic effects and identifies their molecular targets. Furthermore, the results revealed that DAH was able to boost the anticancer effects of the drug SOR and reduce liver damage caused by HCC in mice. This suggests that DAH could be a potential therapeutic agent against liver cancer.

RESUMO

Cancer cells can become resistant to existing treatments over time, so it is important to develop new treatments that target different pathways to stay ahead of this resistance. Many cancer treatments have severe side effects that can be debilitating and even life-threatening. Developing drugs that can effectively treat cancer while minimizing the risks of these side effects is essential for improving the quality of life of cancer patients. The study was designed to explore whether the combination of dicinnamoyl-L-tartaric (CLT) and sorafenib ((SOR), an anti-cancer drug)) could be used to treat hepatocellular carcinoma (HCC) in the animal model and to assess whether this combination would lead to changes in certain biomarkers associated with the tumour. In this study, 120 male mice were divided into 8 groups of 15 mice each. A number of biochemical parameters were measured, including liver functions, oxidative stress (malondialdehyde, (MDA); nitric oxide (NO)), and antioxidative activity (superoxide dismutase (SOD), and glutathione peroxidase (GPx)). Furthermore, the hepatic expressions of Bax, Beclin1, TNF-α, IL1ß, and BCl-2 genes were evaluated by qRT-PCR. The combination of SOR and CLT was found to reduce the levels of liver enzymes, such as AST, ALT, ALP, and GGT, and reduce the pathological changes caused by DAB and PB. The upregulation of TNF-α, IL1ß, and Bcl-2 genes suggests that the CLT was able to initiate an inflammatory response to combat the tumor, while the downregulation of the Bax and Beclin1 genes indicates that the CLT was able to reduce the risk of apoptosis in the liver. Furthermore, the combination therapy led to increased expression of cytokines, resulting in an enhanced anti-tumor effect.

RESUMO

The burden of cancer diseases is increasing every year, therefore, the demands to figure out novel drugs that can retain antitumor properties have been raised. This study aimed to investigate the anti-tumor properties of amygdalin (Amy) against Ehrlich ascites carcinoma (EAC) bearing mice and its protective properties against liver damage. Amy and the standard anticancer drug Sorafenib (Sor) were given alone or in combination to Swiss albino female mice that had been injected with EAC cells. Biochemical parameters of liver function (AST, ALT, GGT, total protein, albumin), tumor volume, oxidative stress [malondialdehyde, (MDA)] and antioxidative [superoxide dismutase (SOD), and reduced glutathione (GSH)] markers were measured. The hepatic expression of the antioxidant-related gene [nuclear factor erythroid-2-related factor 2 (Nrf2)], the migration-related gene [matrix metalloprotease 9 (MMP9)], and the angiogenesis-related gene [vascular endothelial growth factor (VEGF)] were evaluated by qPCR. The results revealed that EAC-bearing mice treated with Amy and/or Sor showed a decrease in the tumor burden and hepatic damage as evidenced by (1) decreased tumor volume, number of viable tumor cells; (2) increased number of dead tumor cells; (3) restored the liver function parameters; (4) reduced hepatic MDA levels; (5) enhanced hepatic GSH and SOD levels; (6) upregulated expression of Nrf2; (7) downregulated expression of MMP9 and VEGF, and (8) improved hepatic structure. Among all treatments, mice co-treated with Amy (orally) and Sor (intraperitoneally) showed the best effect. With these results, we concluded that the Amy improved the antitumor effect of Sor and had a protective role on liver damage induced by EAC in mice.

RESUMO

Abstract Obesity results in detrimental effects on different body organs. Metformin (Met) has described to decrease the body weight of obese patient and to control the glucose level. This study aimed to evaluate the role of Met treatment for long period on the functionality of liver and kidney organs of obese rats. Forty rats were used in this study and divided into four groups as the following: group 1 (Gp1) was served as a negative control that administered orally with 200 µL of H2O. Gp2 of rats was administered with Met (200 mg/kg) daily for a month. Gp3 was obese rats, and Gp4 was obese rats administered with Met as in Gp2. All rats were sacrificed to analyze hematological, biochemical, and histopathological changes. The results showed that Met decreased the body weight of both naïve and obese rats, however, it caused hepato-renal dysfunctions in obese rats as evidenced by increased the levels of ALT, AST, urea, creatinine, and MDA and decrease in the antioxidants biomarkers (SOD, Cat and GSH). Collectively, Met causes liver and kidneys dysfunctions of obese rats and is not recommended to described for obese persons.

RESUMO

The possible renal and hepatic toxicities of ethylenediaminetetraacetic acid (EDTA) in bean cooking media were studied using 100 male albino mice. Two sublethal doses of EDTA were used to explore their toxic effects; 20 mg/kg and 200 mg/kg, which corresponded to 1/100th and 1/10th of LD50, respectively. Accordingly, the toxicity study was performed using 50 mice, divided into five groups (n = 10/group) as follows: group 1 (Gp1) served as a negative control and was orally administered normal saline; group 2 (Gp2) was administered the bean cooking medium; group 3 (Gp3) was administered EDTA (200 mg/kg); group 4 (Gp4) was administered bean cooking medium containing 20 mg/kg of EDTA; and group 5 (Gp5) was administered bean cooking medium containing 200 mg/kg of EDTA. The results showed no significant changes in liver and kidney functions in Gp2 while Gp3, Gp4, and Gp5 exhibited significant increases in adverse liver and kidney function markers. Hematocrit values were significantly decreased in Gp3 and Gp5, while the total white blood cells counts were significantly decreased in Gp3 and significantly increased in Gp5. The number of platelets was decreased in Gp3, Gp4, and Gp5. The blood levels of sodium (Na+), iron (Fe2+), and calcium (Ca2+) were decreased in Gp3, Gp4, and Gp5 due to the chelating effects of EDTA. The hepatic and renal architectures were disorganized in Gp3, Gp4, and Gp5 with some hemorrhagic manifestations in livers and kidneys of mice. These results demonstrate that EDTA in bean cooking is harmful in mice under the conditions of this study, and the potentially harmful effects in humans supports restricting its use.

RESUMO

Ethylenediamine tetraacetic acid (EDTA) is used in various medical applications. The aim of this study is to investigate the antitumor efficacy of EDTA alone or with cisplatin (Cis). Fifty male albino mice were used to assess the median lethal dose (LD50) of EDTA via intraperitoneal (i.p) injection. To determine the antitumor activity, fifty female albino mice were divided into five groups as the following; Group 1 (Gp1) was negative control; (Gp2-5) inoculated i.p with 2×106 Ehrlich Ascites Carcinoma (EAC) cells/mouse. After one day, Gp3, Gp4 and Gp5 injected with Cis (2 mg/kg), EDTA (25 mg/kg) and Cis (2 mg/kg)/EDTA (25 mg/kg) for six days, respectively. At day 14, all groups were sacrificed to assess the tumor profile, liver enzymes (alanine transaminases and aspartate transaminases), kidney function (urea and creatinine) and electrolytes (Na+, K+ and Ca2+). The results showed that the i.p LD50 of EDTA was 250 mg/kg. Treatment with EDTA alone did not show any antitumor activity and did not interfere with the antitumor efficacy of Cis. Biochemical findings revealed that EDTA had mild toxicity on liver and kidneys functions. In summary, EDTA had no antitumor effect and did not alter the Cis efficacy.

RESUMO

Ethylenediamine terta-acetic acid (EDTA) used to accelerate the cooking process of Vicia (V. faba) beans. In this study, the effect of cooking with EDTA on the nutritional value of V. faba beans was addressed. Water contents, total proteins, lipids, carbohydrates, minerals and amino acids were determined before and after boiling with EDTA (2 g/L). In both of whole beans and seed coats, the water content was increased after boiling with EDTA. In contrast, the levels of proteins, lipids and carbohydrates were significantly decreased in both the whole beans and seed coats upon boiling with EDTA. Furthermore, the levels of sodium were increased while, the levels of other minerals were decreased. All amino acids were significantly decreased in the whole beans and increased in the seed coats after boiling with EDTA. EDTA addition to V. faba beans during the cooking process decreased the nutritional value of the cooked V. faba beans.

RESUMO

Abstract In a recent study, the treatment of different human cancer cell lines in vitro with ethylene diamine tetra-acetic acid (EDTA) showed a promising anticancer activity which could be a novel promising approach for cancer treatment. The aim of this study is to address the ability of EDTA to enhance the antitumor efficacy of the low dose of cisplatin (Cis) treatment in Ehrlich ascetic carcinoma (EAC) bearing mice. Sixty female albino mice were divided into six groups. The 1st group of mice was served as a negative control. 2nd - 6th groups were inoculated intraperitoneal (i.p) with 2×106 EAC cells/mouse. After one day of inoculation, the 2nd, 3rd and 4th groups were injected daily for 6 days (early treatment) with phosphate buffer saline, low dose of Cis and Cis/EDTA, respectively. After six days, the 5th and 6th groups were injected with the low dose of Cis and Cis/EDTA for 6 consecutive days (late treatment), respectively. At day 14, all groups of mice were sacrificed, sera were collected for biochemical assessment, then tumor volumes, counts, live and dead cells were determined from all groups. The results showed that EDTA co-treatment enhanced the efficacy of low dose of Cis at early and late time points. In addition, EDTA co-treatment potentially ameliorated the Cis-induced side effects on liver and kidney functions. In summary, co-therapy with EDTA could enhance the chemotherapeutic efficacy of low dose of Cis.
