objective(s): the aim of this study was to determine the important molecules involved in apoptosis induction by opium in jurkat cell line. materials and methods: jurkat cells were incubated 48 hrs with2.86×10-5 g/ml concentration of opium and apoptosis as well as expression levels of related molecules weremeasured. results: our results demonstrated that 50.3±0.2 percent of opium treated jurkat ...

In this study, colchicine's cytotoxic effects on SNU-1 cells were examined, and a probable mechanism behind its cytotoxicity was revealed. According to the results of colchicine displayed considerable with an IC50 value 14.81ng/ml when it administered for 24 hours at different doses ranging from 5 100ng/ml. Furthermore, according mechanistic studies, usege significantly increased both early lat...

Mitochondria are vital organelles to eukaryotic cells. Damage to mitochondria will cause irreversible cell death or apoptosis. In this report, we aim at programmed cancer cell death via specific mitochondrial damage. Herein, a functionalized pro-apoptotic peptide demonstrates a dual-targeting capability using folic acid (FA) (targeting agent I) and triphenylphosphonium (TPP) cation (targeting a...

HIGHLIGHTS Chondrocytes express PAR-4 in the nucleus and cytoplasm; Vitamin D reduces pro-apoptotic proteins caspase-3; caspase-3 may be potential therapeutic targets for osteoarthritis.

background and aims:in neurodegenerative disorders,oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages which can lead to apoptosis. pro-apoptotic and anti-apoptotic gene expressions are changed during the cell differentiation that affect cell viability and differentiation. therefore, this study was conducted to determine the effects of hyd...

The pro-apoptotic "BH3 domain-only" proteins of the Bcl-2 family (e.g. Bid and Bad) transduce multiple death signals to the mitochondrion. They interact with the anti-apoptotic Bcl-2 family members and induce apoptosis by a mechanism that requires the presence of at least one of the multidomain pro-apoptotic proteins Bax or Bak. Although the BH3 domain of Bid can promote the pro-apoptotic assem...

Purpose: To determine the inhibitory potential of betulinic acid on pro-survival signaling pathway in glioblastoma.Methods: Changes viabilities glioma cells and primary astrocytes were measured using 3-(4, 5dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Apoptotic changes analyzed Hoechst 33342 staining Annexin V-FITC/PI kits. Western blotting was used for assaying protein e...
