RESUMEN

The incidence rate of cancer is increasing year by year due to the aging of the population, unhealthy living, and eating habits. At present, surgery and medication are still the main treatments for cancer, without paying attention to the impact of individual differences in health management on cancer. However, increasing evidence suggests that individual psychological status, dietary habits, and exercise frequency are closely related to the risk and prognosis of cancer. The reminder to humanity is that the medical concept of the unified treatment plan is insufficient in cancer treatment, and a personalized treatment plan may become a breakthrough point. On this basis, the concept of "Humanistic Health Management" (HHM) is proposed. This concept is a healthcare plan that focuses on self-health management, providing an accurate and comprehensive evaluation of individual lifestyle habits, psychology, and health status, and developing personalized and targeted comprehensive cancer prevention and treatment plans. This review will provide a detailed explanation of the relationship between psychological status, dietary, and exercise habits, and the regulatory mechanisms of cancer. Intended to emphasize the importance of HHM concept in cancer prevention and better prognostic efficacy, providing new ideas for the new generation of cancer treatment.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Compound Kushen (Sophora flavescens Aiton) Injection (CKI) is a Chinese herbal injection made from extracts of Kushen and Baituling (Heterosmilax japonica Kunth), containing matrine (MAT), oxymatrine (OMT) and other alkaloids with significant anti-tumor activity, and is widely used as an adjuvant treatment for cancer in China. AIM OF THE STUDY: The existing systematic reviews/meta-analyses (SRs/MAs) were re-evaluated to provide a reference for the clinical application of CKI. MATERIALS AND METHODS: SRs/MAs of CKI adjuvant therapy for cancer-related diseases were searched in four English language databases: PubMed, Embase, Web of Science, and Cochrane Library, all from the time of database construction to October 2022. 5 researchers independently conducted literature search and identification according to the inclusion criteria, and the data of the final literature were independently extracted, and finally the AMSTAR 2 tool, PRISMA statement and GRADE classification were used to evaluate the methodological quality of the included SRs/MAs, the degree of completeness of reporting and the quality of evidence for outcome indicators. Database registration: PROSPERO ID:CRD42022361349. RESULTS: Eighteen SRs/MAs were finally included, with studies covering non-small cell lung cancer, primary liver cancer, gastric cancer, colorectal cancer, breast cancer, head and neck tumors, and cancer-related bone pain. The evaluation showed that the methodological quality of the included literature was extremely low, but most of the literature reported relatively complete entries; nine clinical effectiveness indicators for non-small cell lung cancer and digestive system tumors were rated as moderate in the GRADE quality of evidence, and the quality of other outcomes was low to very low. CONCLUSION: CKI is a potentially effective drug for the adjuvant treatment of neoplastic diseases and may be more convincing for the adjuvant treatment of non-small cell lung cancer and digestive system tumors; however, due to the low methodological and evidentiary quality of the current SRs, their effectiveness needs to be confirmed by more high-quality evidence-based medical evidence.

RESUMEN

Kaempferol (KAE) is a naturally occurring flavonoid compound with antitumor activity. However, the low aqueous solubility, poor chemical stability, and suboptimal bioavailability greatly restrict its clinical application in cancer therapy. To address the aforementioned limitations and augment the antitumor efficacy of KAE, we developed a kaempferol nanosuspensions (KAE-NSps) utilizing D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) as a stabilizing agent, screened the optimal preparation process, and conducted a comprehensive investigation of their fundamental properties as well as the antitumor effects in the study. The findings indicated that the particle size was 186.6 ± 2.6 nm of the TPGS-KAE-NSps optimized, the shape of which was fusiform under the transmission electron microscope. The 2% (w/v) glucose was used as the cryoprotectant for TPGS-KAE-NSps, whose drug loading content was 70.31 ± 2.11%, and the solubility was prominently improved compared to KAE. The stability and biocompatibility of TPGS-KAE-NSps were favorable and had a certain sustained release effect. Moreover, TPGS-KAE-NSps clearly seen to be taken in the cytoplasm exhibited a stronger cytotoxicity and suppression of cell migration, along with increased intracellular ROS production and higher apoptosis rates compared to KAE in vitro cell experiments. In addition, TPGS-KAE-NSps had a longer duration of action in mice, significantly improved bioavailability, and showed a stronger inhibition of tumor growth (the tumor inhibition rate of high dose intravenous injection group was 68.9 ± 1.46%) than KAE with no obvious toxicity in 4T1 tumor-bearing mice. Overall, TPGS-KAE-NSps prepared notably improved the defect and the antitumor effects of KAE, making it a promising nanodrug delivery system for KAE with potential applications as a clinical antitumor drug.

RESUMEN

INTRODUCTION: Traditional Chinese medicine (TCM) injections, as a relatively safe and low-cost treatment, have been widely used in the prevention and treatment of anthracyclines-induced cardiotoxicity in China. However, the quality of the relevant systematic reviews and meta-analyses published in recent years is uneven, so that the effectiveness and safety of TCM injections in preventing and treating anthracyclines-induced cardiotoxicity remain to be discussed. A systematic overview is therefore needed to provide a more advanced evidentiary reference for clinical practice. METHODS: Eight Chinese and English databases were searched by computer to screen the meta-analyses/systematic reviews on the efficacy of traditional Chinese medicine injections for the prevention and treatment of anthracyclines-induced cardiotoxicity from the database establishment to October 2022. The methodological quality and evidence quality of outcome indicators included in the study were evaluated by AMSTAR 2 tool, PRISMA statement and GRADE classification. RESULTS: A total of 7 articles were included in the study. The quality evaluation of AMSTAR 2 showed that 7 studies were extremely low-level; PRISMA stated that the evaluation results showed that the reports of 7 studies were of intermediate quality; The GRADE rating indicated that most of the evidence was of low quality. CONCLUSION: The methodological quality and evidence quality of meta-analysis/system evaluation concerning the prevention and treatment of anthracyclines-induced cardiotoxicity by Chinese medicine are currently low, and the effectiveness of Chinese medicine in the treatment of anthracyclines-induced cardiotoxicity needs more high-quality evidence-based evidence.

RESUMEN

This study aimed to enhance the utilization value of sweet corn cob, an agricultural cereal byproduct. Sweet corn cob polysaccharide-ron (III) complexes were prepared at four different temperatures (40 °C, 50 °C, 60 °C, and 70 °C). It was demonstrated that the complexes prepared at different temperatures were successfully bound to iron (III), and there was no significant difference in chemical composition; and SCCP-Fe-C demonstrated the highest iron content. The structural characterization suggested that sweet corn cob polysaccharide (SCCP) formed stable ß-FeOOH iron nuclei with -OH and -OOH. All the four complexes' thermal stability was enhanced, especially in SCCP-Fe-C. In vitro iron (III) release experiments revealed that all four complexes were rapidly released and acted as iron (III) supplements. Moreover, in vitro antioxidant, α-glucosidase, and α-amylase inhibition studies revealed that the biological activities of all four complexes were enhanced compared with those of SCCP. SCCP-Fe-B and SCCP-Fe-C exhibited the highest in vitro antioxidant, α-glucosidase, and α-amylase inhibition abilities. This study will suggest using sweet corn cobs, a natural agricultural cereal byproduct, in functional foods. Furthermore, we proposed that the complexes prepared from agricultural byproducts can be used as a potential iron supplement.

RESUMEN

Cutting off glucose provision by glucose oxidase (GOx) to famish tumors can be an assistance with chemotherapy to eliminate cancer cells. Co-encapsulation of GOx and chemotherapeutics (doxorubicin) within pH-sensitive metal-organic frameworks (MOFs) could disorder metabolic pathways of cancer cells and generate excessive intracellular reactive oxygen species (ROS), together. To prevent premature leach of GOx from the porous channels of MOFs, polydopamine (PDA) was deposited on the surface of MOFs, which endowed the delivery system with photothermal conversion ability. Our nanoscaled co-delivery system (denoted as DGZPNs) remains stable with low amount of drug leakage under simulated physiological conditions in vitro and internal environment, while they are triggered to release doxorubicin (DOX) and GOx in acid tumor microenvironment and at high temperature for reinforced chemotherapy. NIR laser irradiation also activates superior photothermal conversion efficiency of PDA (36.9 %) to initiate hyperthermia to ablate tumor tissue. After being phagocytized by 4 T1 cells (breast cancer cells), the DGZPNs delivery system showed a superior therapeutic efficacy with a tumor growth inhibition of 88.9 ± 6.6 % under NIR irradiation, which indicated that the starvation-assisted chemo-photothermal therapy prompts the significant advance of synergistic therapy in a parallelly controlled mode.

RESUMEN

In this study, medium-chain fatty acid (MCFA) generation from mixed sludge (including primary sludge and waste activated sludge) was investigated without additional electron donors (EDs). 0.5 g COD/L of MCFAs was produced and the in situ generated ethanol could serve as the EDs during the anaerobic fermentation of mixed sludge without thermal hydrolysis process (THP) pretreatment. THP increased the MCFA production by approximately 128% in the anaerobic fermentation. During 102 days of operation, the fermentation of THP pre-treated mixed sludge stably generated 2.9 g COD/L MCFAs. The self-generated EDs could not maximize MCFA production, and external addition of ethanol improved MCFA yield. Caproiciproducens was the dominant chain-elongating bacteria. PICRUST2 revealed that both fatty acid biosynthesis and reverse ß-oxidation pathways could participate in MCFA synthesis, and ethanol addition could enhance the contribution of the reverse ß-oxidation pathway. Future studies should focus on the improvement of MCFA production from THP-assisted sludge fermentation.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Radix Polygalae, a commonly used traditional Chinese herb, has conventionally functioned in tranquilization and sedation, where anti-inflammation may be the underlying mechanism. AIM OF THE STUDY: Chronic restraint stress (CRS), a risk factor for the etiology of intestinal disorders, was used in the present study to examine whether Radix Polygalae extract (RPE) could modulate colonic dysfunction in CRS rats. MATERIALS AND METHODS: Wistar rats were exposed to 28-day CRS (6 h daily), and RPE (135 mg/kg and 270 mg/kg) was intragastrically administered 1 h before CRS. Subsequently, the gut microbiota was determined using metagenomic sequencing. Colonic proinflammatory interleukin-1ß, -6, and -18 were assayed using qRT-PCR and ELISA. Tight junction proteins were quantified by qRT-PCR and western blotting (WB), and tryptophan metabolic enzymes and metabolites were determined using qRT-PCR and UFLC-QTRAP-5500/MS. Moreover, protein expression of colonic tight junction proteins, NF-κB-NLRP3 signaling involved in the underlying mechanism of RPE were detected by WB. RESULTS: RPE significantly decreased proinflammatory cytokines and reshaped the gut microbiota, especially the probiotics, including Lactobacillus and Bacteroides. Moreover, RPE could modulate the metabolite contents and enzyme expression associated with colonic tryptophan-kynurenine (TRP-KYN) metabolism and could increase tight junction protein expression in CRS rats. Furthermore, RPE inhibited the activation of NF-κB-NLRP3 signaling in the colon of CRS rats. CONCLUSION: RPE could modulate colonic inflammation, colonic microbiota, tight junction, TRP-KYN metabolism and NF-κB-NLRP3 signaling to reach a colonic balance of CRS rats. The present study helped us to better understand and appreciate the various beneficial effects of RPE.

RESUMEN

Theranostics is a new type of biomedical technology that organically combines the diagnosis and therapy of diseases. Among molecular imaging techniques, the integration of photoacoustic (PA) and fluorescence (FL) imaging modes with high sensitivity and imaging depth provides precise diagnostic outcomes. Gold nanorods (Au NRs) are well-known contrast agents for PA imaging and photothermal therapy. However, their high toxicity, poor biocompatibility, rapid clearance, and the need for an external laser source limit their application. Therefore, modification of Au NRs with carbon-based nanomaterials (CBNs) is done to obtain a multifunctional dual-mode gold-based nanoformulation (mdGC), which preforms dual-mode imaging of PA and FL. The results show that mdGC promotes tumor cell apoptosis and exhibits good antitumor performance through the mitochondria-mediated apoptotic pathway by increasing the production of intracellular reactive oxygen species, reducing mitochondrial membrane potential, and regulating the expression of apoptosis-related genes. The targeting rate of mdGC to tumor tissue is up to 20.71 ± 1.94% ID g-1 ; the tumor growth inhibition rate is as high as 80.44% without external laser sources. In general, mdGC is a potential multifunctional diagnostic and therapy integrated nanoformulation.

RESUMEN

Angelica sinensis (AS) is a common Traditional Chinese Medicine used for tonifying blood in China. Unprocessed AS and its four kinds of processed products (ASs) are used to treat blood deficiency syndrome in the country. The different blood-tonifying mechanisms of ASs remain unclear. In this work, a novel method integrating metabolomics and hematological and biochemical parameters was established to provide a complementary explanation of blood supplementation mechanism of ASs. Our results revealed that different ASs exhibited various blood supplementation effect, and that AS parched with alcohol demonstrated the best blood supplementation effect. Eight metabolites from liver tissue and 12 metabolites from spleen tissue were considered to be potential biomarkers. These biomarkers were involved in four metabolic pathways. Correlation analysis results showed that l-aspartic acid and l-alanine (spleen tissue), linoleic acid, and l-cystathionine (liver tissue) exhibited a high positive or negative correlation with the aforesaid biochemical indicators. The blood-supplementation effect mechanism of ASs were related to four metabolic pathways. l-Aspartic acid and l-alanine (spleen tissue), linoleic acid, and l-cystathionine (liver tissue) were the four key metabolites associated with the blood supplementation effect of ASs. This study gives a complementary explanation of the blood supplementation effect and mechanism of action of ASs.

RESUMEN

Metal-organic gels (MOGs) are new soft materials with the characteristics of high colloidal stability, superb luminescence properties, and facile synthesis. Herein, we develop for the first time a host-guest interaction-based and MOG-based biosensor with aggregation-induced electrochemiluminescence (ECL) enhancement for M.SssI methyltransferase (M.SssI MTase) assay. This biosensor employs a MOG as the luminophor and potassium persulfate as the coreactant, and the formation of the Ag-MOG from the aggregation of silver nanoclusters can induce significant ECL enhancement. Two complementary single-stranded DNAs (ssDNAs, i.e., biotinylated DNA-1 and Fc-labeled DNA-2) that contain specific recognition sequence 5'-CCGG-3' can form a double-stranded DNA (dsDNA) probe. In the absence of M.SssI MTase, the dsDNA probe will be digested by restriction endonuclease HpaII, leading to the release of Fc from magnetic beads (MBs). The ß-CD can specifically recognize the released Fc through guest-host interaction, resulting in the quenching of an ECL signal. In contrast, the presence of M.SssI MTase enables the formation of fully methylated dsDNA, which cannot be cleaved by HpaII, making Fc remain on the MB surface and consequently generating an improved ECL signal. This biosensor can specifically detect M.SssI MTase with a linear range of 0.05-100 U mL-1 and a limit of detection of 3.5 × 10-3 U mL-1, and it enables accurate detection of M.SssI MTase in human serum. In addition, it can be used for inhibitor screening, with wide applications in drug discovery and disease diagnosis.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Radix Polygalae (RP) has been traditionally used for the treatment of various psychiatric disorders in East Asia. AIM OF THE STUDY: Depression is a severe mental disease with high prevalence in people, and neurobiology changes of depression are not fully clarified yet. The present study aimed to investigate the antidepressant effect and underlying mechanism of RP in behavioral despair mice and chronic restraint stress (CRS)-induced rats. MATERIALS AND METHODS: ICR mice were treated with various doses of RP (0.13-1.0 g/kg) for 14 days and then subjected to forced swimming test (FST). Wistar rats were exposed to 6-hour restraint stress daily for 28 days, and RP (0.5 and 1 g/kg) was administered by gavage 1 h prior to CRS procedure. Subsequently, behavioral tests were performed and brains were collected for biochemical analysis. RESULTS: RP reduced immobility time of mice in FST and reversed abnormal behaviors of rats induced by CRS in sucrose preference test, novelty-suppressed feeding test, open field test and FST. Moreover, RP could enhance the expression of LC3-II and beclin1 and decrease the level of p62 both in cortex of mice and prefrontal cortex (PFC) of rats, and regulate the dysfunction of AMPK-mTOR pathway in PFC of CRS rats. Activated microglia, impaired astrocyte, elevated protein expression of NLRP3, ASC and caspase-1, and increased mRNA levels of proinflammatory cytokines were observed in PFC of CRS rats, all of which were corrected by RP treatment. CONCLUSION: RP exerted remarkable antidepressant activity in behavioral despair mice and CRS-induced rats, probably by promoting autophagy and inhibiting neuroinflammation.

RESUMEN

ETHNOPHARMACOLOGY RELEVANCE: The water extract of Panax ginseng (GT) and Polygala tenuifolia (YT), the main constituents of the commonly used kai-xin-san formula of traditional Chinese medicine, represents SY. It possesses strong neuroprotective effects. Using behavioural tests, we have previously established that the SY formulation exerts superior antidepressant activity than that of GT or YT. AIM: To elucidate the impact of SY treatment on chronic unpredictable mild stress (CUMS)-induced depressive-like behaviours and the prospective mechanism related to hippocampal neurogenesis and the BDNF signaling pathway. METHODS: We exposed Sprague-Dawley rats (male; 180-200 g) to CUMS for 35 days. The rats in the experimental treatment groups were daily treated with either fluoxetine (10 mg kg-1d-1) or SY (67.5, 135, or 270 mg kg-1d-1) orally until the behavioural tests (tail suspension test [TST], novelty-suppressed feeding test [NSFT], sucrose preference test [SPT], and forced swim test [FST]) were completed. We assessed the modifications in the hippocampal neurogenesis and the BDNF signaling pathway post-treatment with CUMS and SY. Additionally, K252a, a tyrosine protein kinase inhibitor, was utilized to evaluate the antidepressant mechanisms of SY. RESULT: s: The results of SPT, NSFT, FST, and TST in CUMS-exposed rats confirmed the antidepressant actions of SY. Additionally, SY treatment induced the BDNF signaling pathway and reversed the hippocampal neurogenesis caused by CUMS. Moreover, we found that the TrkB antagonist K252a blocked SY effects on behavioural improvement, inhibited the incremental effects of SY on hippocampal neurogenesis, and eliminated the impact of SY on BDNF-TrkB signaling activation. Thus, the impact of SY treatment on BDNF signaling molecules (pAkt, pERK1/2, and pCREB) were significantly inhibited by K252a. CONCLUSIONS: This study showed that SY acted as an antidepressant in rats exhibiting CUMS-induced depressive-like behaviours, and was facilitated by promoting hippocampal neurogenesis and the BDNF signaling pathway activation. Thus, SY could act as a potential novel supplement or adjuvant to prevent or treat clinical depressive disorders.

RESUMEN

BACKGROUND: This report summarizes the clinical characteristics of intractable anemia as part of the clinical presentation of Hirschsprung's disease (HD) and aims to strengthen clinicians' ability to recognize early signs of HD. CASE PRESENTATION: An 11-year-old boy with a 6-year history of intractable anemia, low hemoglobin level (55 g/L), poor response to oral iron supplementation and blood transfusion, and difficulty with defecation was diagnosed with HD. A 19-month-old boy with a 3-month history of intractable anemia, low hemoglobin level (64 g/L), poor response to oral iron supplementation and blood transfusion, delayed meconium passage, and history of intestinal obstruction was also diagnosed with HD. Both patients underwent surgery, after which anemia was corrected effectively in both cases. Two more cases of intractable anemia as the chief complaint and diagnoses of HD over different durations since the onset of anemia (ranging from 1.7 years to 21 years) were identified in a literature search. Both patients underwent surgery, after which anemia was corrected. CONCLUSIONS: Intractable anemia as part of the clinical presentation of HD is extremely rare. Detailed inquiries of medical histories and physical examinations are key to early diagnoses and preventing misdiagnoses. Anemia in HD patients may primarily be caused by impaired iron absorption due to HD.

RESUMEN

CONTEXT: Angelica sinensis (Oliv.) Diels (Apiaceae) (syn. Angelica polymorpha Maxim var. sinensis Oliver) processed with yellow rice wine (WAS) has a blood-supplementing effect. OBJECTIVE: To establish an optimal technology for preparing water decoction of WAS (WASD), and screen blood-supplementing fractions. MATERIALS AND METHODS: Ferulic acid and crude polysaccharide were used in optimizing the preparation technology for WASD through response surface methodology. The independent variables were liquid-solid ratio, soaking time, and extraction time. Eighty Kunming mice were randomly divided into normal control, model, and six intervention groups (n = 10). The intervention groups were given different WASD fractions by gavage (5 or 10 g/kg). The model intervention groups received acetylphenyl hydrazine (subcutaneous injection) and cyclophosphamide (intraperitoneal injection). Duration of study, 9 days. The components of blood-supplementing fractions were analyzed. RESULTS: The optimum extraction parameters were liquid-solid ratio, 7.69:1 mL/g; soaking time, 119.78 min; and extraction time, 143.35 min. The optimal OD value was 0.8437. RBC, WBC, and Hb in the water fraction (5, 10 g/kg) and n-butanol fraction (10 g/kg) intervention groups increased significantly compared with the model group (p < 0.05). Polysaccharide and caffeic acid contents of water fraction were 252.565 and 0.346 µg/mg, respectively; ferulic acid was not detected. Caffeic acid and ferulic acid contents of n-butanol fraction were 1.187 and 0.806 µg/mg, respectively, polysaccharide was not detected. CONCLUSIONS: The optimum preparation technology of WASD was obtained, and the water, n-butanol fractions were blood-supplementing fractions. This study provides a theoretical foundation for further application of WAS in the pharmaceutical industry.

RESUMEN

Resistance to radiotherapy is frequently encountered in clinic, leading to poor prognosis of cancer patients. Long noncoding RNAs (lncRNAs) play important roles in the development of radioresistance due to their functions in regulating the expression of target genes at both transcriptional and posttranscriptional levels. Exploring key lncRNAs and elucidating the mechanisms contributing to radioresistance are crucial for the development of effective strategies to reverse radioresistance, which however remains challenging. Here, actin filament-associated protein 1 antisense RNA1 (lncAFAP1-AS1) is identified as a key factor in inducing radioresistance of triple-negative breast cancer (TNBC) via activating the Wnt/ß-catenin signaling pathway. Considering the generation of a high concentration of reduction agent glutathione (GSH) under radiation, a reduction-responsive nanoparticle (NP) platform is engineered for effective lncAFAP1-AS1 siRNA (siAFAP1-AS1) delivery. Systemic delivery of siAFAP1-AS1 with the reduction-responsive NPs can synergistically reverse radioresistance by silencing lncAFAP1-AS1 expression and scavenging intracellular GSH, leading to a dramatically enhanced radiotherapy effect in both xenograft and metastatic TNBC tumor models. The findings indicate that lncAFAP1-AS1 can be used to predict the outcome of TNBC radiotherapy and combination of systemic siAFAP1-AS1 delivery with radiotherapy can be applied for the treatment of recurrent TNBC patients.

RESUMEN

An 8-week feeding trial was conducted to evaluate the effects of dietary xylanase supplementation on growth performance, digestive enzyme activity, intestinal morphology parameter, intestinal microbiome diversity, and carbohydrate metabolism for juvenile large yellow croaker (Larimichthys crocea). Four levels of xylanase were added to basal diets (0, 600, 1200, and 1800 U kg-1). The results indicated that fish fed the 1200 U kg-1 xylanase diet had higher weight gain than those fed the 0 and 600 U kg-1 xylanase diet. The highest intestinal folds and microvillous height were observed at fish fed the 1200 U kg-1 xylanase diet. High-throughput sequencing revealed that the majority of reads derived from the large yellow croaker digesta belonged to members of Proteobacteria followed by Chloroflex, Bacteroidetes, Spirochaetae, and Firmicute. Supplementation of xylanase in diets increased the relative abundance of Bacteroides and Gemmatimonadete. The higher hepatic glucokinase (GK) and glucose-6-phosphate dehydrogenase (G6PD) activities were observed in fish fed the xylanase supplementation diet. Accordingly, dietary xylanase supplementation upgraded the relative expressions of gk and g6pd genes in liver. In conclusion, optimum dietary xylanase supplementation (600-1200 U kg-1) could improve the growth performance, optimize the intestinal morphology structure and microbiota constitution, and enhance the ability of carbohydrate utilization of juvenile large yellow croaker.

RESUMEN

20(S)-Rh2 is a ginsenoside isolated from Panax ginseng, which exhibits anti-cancer activities on various human cancer cells. A novel 20(S)-Rh2 derivative, 2-Deoxy-Rh2 was synthesized and hybridized with protopanaxadiol and 2-deoxy-glucose in an attempt to enhance the anticancer activity. Through screening the antitumor effect against various cell lines by MTT assay, 2-Deoxy-Rh2 especially resulted in a concentration-dependent and time-dependent inhibition of viability in MCF-7 human breast cancer cells. Multiple methods were used to explore the cellular and molecular mechanisms of 2-Deoxy-Rh2 as a potent anti-cancer agent. In MCF-7 cells, 2-Deoxy-Rh2 triggered apoptosis, stimulated ROS production and disrupted normal mitochondrial membrane potential. Meantime, 2-Deoxy-Rh2 eff ;ectively suppressed the glucose uptake capabilities and intracellular ATP production. The cellular oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) were significantly decreased in response to 2-Deoxy-Rh2, which were carried out to assess the overall glycolytic flux and mitochondrial respiration. Docking studies and molecular dynamics simulations were performed to verify the binding mode of 2-DG and 2-Deoxy-Rh2 with hexokinase II, with results showing that 2-Deoxy-Rh2 could easily fit into the similar active site of 2-DG, finally binding to hexokinase II to suppress glycolysis. Taken together, the results suggest that 2-Deoxy-Rh2 exhibited remarkable anticancer activity based on regulating mitochondrial apoptosis pathway, dampening glycolysis and inhibiting mitochondrial respiration, which support development of 2-Deoxy-Rh2 as a potential agent for cancer therapy.

RESUMEN

Cajaninstilbene acid (CSA), a bioactive constituent isolated from pigeon pea leaves, exhibited neuroprotective activities in previous studies. The present study aims to evaluate the antidepressant effects of CSA by using behavioral despair models of tail suspension test (TST) and forced swimming test (FST), and a chronic unpredictable mild stress (CUMS) model. CSA (30 or 60 mg/kg), intragastrically administrated for 7 days, could significantly reduce the immobility time of mice in TST and FST. CSA treatment (15 or 30 mg/kg) significantly reversed the depressive-like behavioral changes of mice induced by 3 or 6 weeks CUMS that caused the decrease of sucrose preference, the increase of latency to feed in the novelty-suppressed feeding test, and the increase of immobility time in TST of mice. Furthermore, the related mechanisms of the effect were explored by accessing the metabolite levels of kynurenine pathway of tryptophan metabolism and the expression of some related proteins in cerebral cortex of CUMS mice. Our results showed that the kynurenine pathway was upregulated after CUMS, while the alteration could be significantly reversed by CSA. CSA also reversed the CUMS-induced decrease in the levels of BDNF, PSD-95, p-Akt/Akt and p-mTOR/mTOR. Therefore, the antidepressant-like effects of CSA might be achieved through regulating tryptophan metabolism, promoting BDNF and PSD-95 expression, and activating Akt/mTOR pathway in the cerebral cortex.

RESUMEN

Background: Increasing attention has been given to the search for neuroprotective ingredients from natural plants. Myrica rubra bark (MRB) has been used in traditional oriental medicine for over thousand years and has potential neuroprotection. Methods and Results: Ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was used to identify the compounds in MRB extract, and the MTT assay was performed to evaluate the neuroprotection of six major compounds from MRB against glutamate-induced damage in PC12 cells. The result displayed nineteen compounds were identified, and myricitrin and myricanol 11-sulfate were shown to have neuroprotection, which prevented cell apoptosis through alleviating oxidative stress by reducing the levels of reactive oxygen species and methane dicarboxylic aldehyde, as well as by enhancing the activities of superoxide dismutase. Conclusions: Several active compounds from MRB may offer neuroprotection and have the potential for the development of new drugs against central nervous system diseases.
