sea cucumbers saponins are triterpenoid glycosides which exert beneficial biomedical effects. this study was performed to assess the effect of saponin extracted from sea cucumber holothuria leucospilota            ( h. leucospilota ) on maturation of mice oocytes and granulosa cells. the germinal vesicles oocytes were collected from 6–8 weeks old naval medical research institute (nmri) mice ova...

background: malignant melanoma is a highly aggressive malignant melanocytic neoplasm which resists against the most conventional therapies. sea cucumber as one of marine organisms contains bioactive compounds such as polysaccharide, terpenoid and other metabolites which have anti-cancer, anti-tumor, anti-inflammatory and antioxidant properties. the present study was designed to investigate the ...

Introduction: In this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. Methods: Bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μM of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan bl...

objective(s):the neuroprotective effect offruit aqueous extract of ziziphus jujuba lam on glucose-induced neurotoxicity in pc12 cells as an appropriate in vitro model of diabetic neuropathy was investigated. materials and methods: cell viability was determined by the mtt assay. cellular reactive oxygen species (ros) generation was measured by dcfh-da analysis. cleaved caspase-3, a biochemical p...

we aimed to develop a cost-effective and robust method to predict drug resistance in individualpatients. representative tissue fragments were obtained from tumors removed from femalepatients, aged 24-74 years old. the tumor tissue was taken by a histopathology’s or a surgeonunder sterile conditions. cells obtained by enzymatic dissociation from tumor after surgery, werecultured as a monolayer f...

biodegradable polymeric nanoparticles (nps) have been intensively studied as a possible way to enhance anti-tumor efficacy while reducing side effects. icd-85, derived from the venom of two separate species of venomous animals, has been shown to exhibit anti-cancer activity. in this report polymer based sodium alginate nanoparticles of icd-85 was used to enhance its therapeutic effects and redu...

The aim of this study is to explore the inhibitory effects of RNA interference (RNAi) targeting NET-1 or combined with sorafenib on HCC in vitro and in vivo and the possible underlying mechanisms. The expressions of NET-1 mRNA and protein were detected by RT-QPCR and western blot. The ability of proliferation was determined by CCK-8 assay. Apoptosis was examined by flow cytometry (FCM). Abiliti...

BACKGROUND To explore the anti-tumor effects of parthenolide in human pancreatic cancer. METHODS BxPC-3 cell, a human pancreatic cancer, was treated with parthenolide at different concentrations. The MTT assay was used to analyze cell viability. Flow cytometry and DNA fragmentation analysis were applied to evaluate apoptosis after parthenolide treatment. The wound closure and cell invasion as...

In this study, a novel compound was isolated, identified, and its chemical structure determined from the extract of roots Senna velutina. addition, we sought to evaluate anticancer potential molecule against melanoma leukemic cell lines identify pathways death involved. To end, anthraquinone isolated barks S. velutina, analyzed by HPLC-DAD, molecular nuclear magnetic resonance (NMR). Subsequent...
