Background: In apoptosis is physiological cell death which eliminates injured and old cells. Any disruption in apoptosis, leads to disease. Resveratrol is a natural polyphenol with estrogen-like, antioxidant and antiinflammatory properties; also it showed cell prolifratory and inhibitory effect. The aim of present study was to determine resveratrol effect on apoptosis of human endometrial epith...

Back ground: Although the cell differentiation is an inseparable part of development in multicellular organisms, the regulating molecular pathway of it still is not fully defined. In the other hand, apoptosis is a fundamental physiological process which plays an essential role in a variety of biological events during development. Moreover, recent studies have found that apoptosis shows several ...

introduction: the tumor suppressor p53 protein can induce apoptosis in some cellular contexts. among the apoptosis-inducing genes, p53 has received the most attention for cancer gene therapy. in this study, the role of dendrosome and lipofectin mediated normal cdna of tp53 into molt-4, ccrf-cem(t-iymphoma) and k562 cell lines was assessed. material and methods: at first, ccrf-cem, mol t-4 and k...

Conducting cell apoptosis pathways is a novel strategy in cancer treatment. This study aimed to explain that C. botrys essential oil could induce apoptosis and arrest the cell cycle in HeLa cells. Cytotoxic and apoptogenic effects of the essential oil of Jerusalem-oak (Chenopodium botrys L.), which was obtained from the aerial parts of the plant, were evaluated in HeLa cells. Cell viability was...

objective: thymoquinone (tq), as the main component of nigella sativa plant, shows anticancer properties. this study was aimed to evaluate the combined effect of tq and tamoxifen (tam) on viability and apoptosis of human breast cancer cell lines. materials and methods: in this experimental study, estrogen positive mcf-7 and estrogen negative mda-mb-231 human breast cancer cell lines were induce...

new approach of breast cancer therapy is developed toward combination therapy with agent that have a specific molecular target. our previous study showed that citrus aurantifolia lime peels ethanolic extract (cpe) increased the sensitivity of mcf-7 cells againts doxorubicin. this study aims to observe the mechanism of combination cpe and doxorubicin in cell cycle modulation and apoptosis on mcf...

objective(s): glioblastoma is the most lethal tumor of the central nervous system. here, we aimed to evaluate the effects of exogenous delivery of p53 and a nanoformulation of curcumin called dendrosomal curcumin (dnc), alone and in combination, on glioblastoma tumor cells. materials and methods: mtt assay was exploited to measure the viability of u87-mg cells against dnc treatment. cells were ...

objective(s):marine organisms are known as a potential source of natural products, which contain bioactive substances with therapeutic properties. sea cucumbers are prominent among marine organisms because of their dietary and therapeutic applications. in addition, they have capacity of synthesizing saponins molecules and other metabolites with therapeutic properties such as antitumor, antimicr...

background propolis is a natural product of bee and caffeic acid phenethyl ester (cape) is a pharmacologically important product of propolis. results cape prevented growth and proliferation of ags human gastric cancer cell line in a concentration-dependent manner with an ic50 of approximately 60 µm by a 24-hour treatment. also cape caused increased induction of apoptosis in ags cells from 1.37 ...

cells are active components in their environment and constantly adjusting their performance to improve extracellular milieu changing. this approach is reflected their tends of maintaining intracellular homeostasis. when the cells encounter stress or pathologic stimuli, they can undergo a new manner (adaptation) and new steady state for achieving viability and function. if the external stress is...
