background gastric cancer is the second most common cause of cancer death worldwide. lentinan was shown to induce apoptosis in gastric cancer cells and could be used for the treatment of gastric cancer. objectives in this study, we analyzed anticancer effect of lentinan, a fungal β-glucan, on the gastric adenocarcinoma cell line (ags). materials and methods we used the dna ladder and tunnel app...

background: metformin is used to lower blood sugar in patients with type ii diabetes. recent research showed that metformin has effects on cancer cell growth. studies show that metformin can induce apoptosis in certain cancer cell lines. in this study, we examined the effect of metformin on apoptosis in the t47d breast cancer cell line. methods : the t47d breast cancer cell line was selected an...

background: molecular targeted therapy by different cell death inducers are recently considered in cancer therapy. the aim of this study was to compare the effect of cisplatin and inositol trisphosphate kinase inhibitor (caffeine) on human breast cancer cell line (mcf-7). the pattern of cell death in mcf-7 cells following the exposure to cisplatin and caffeine in individual and combination form...

objective(s):  being secreted by the pineal gland, melatonin induces cell proliferation in normal cells and induced apoptosis in cancer cells. the purpose of this study was to investigate effects of melatonin on main components and the expression of apoptotic genes in vitrified-thawed testicular germ cells of 6- day–old mice.  materials and methods: testes of neonate balb/c mice were vitrified-...

the p75 pan-neurotrophin receptor (p75ntr) plays a pivotal role in linking the immune system with the nervous system. p75ntr is required for the development of several characteristic features of allergic asthma. also p75ntr upregulated by reactive schwann cells after peripheral nerve injury. moreover p75ntr and rhoa play a critical role in the regulation of apoptosis. to determine whether the d...

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...

conclusions our data showed that inhalation of diazinon during pregnancy increased the hepatocyte area and hepatocyte apoptosis while it decreased the sinusoid area of the fetal liver. materials and methods twenty-five pregnant balb/c mice (25 - 30 gr) were divided into five equal groups in the animal lab of baqiyatallah university of medical sciences, tehran, iran. the normal group was without...

introduction: anabolic – androgenic steroids (aas) are used at high doses by athletes for improving athletic ability, muscle mass and physical appearance. unfortunately, the abuse of these agents has been significantly increased. it has been established that exercise and high doses of aas may influence the hypothalamic-pituitary-gonadal axis, which can in turn affect testicular apoptosis and ma...

apoptosis is a complex network of biochemical and molecular pathway with fine regulatory mechanisms that control the death event during several pathological situations in multi cellular organisms. it is the part of normal development that occurs in a variety of diseases and is known as aberrant apoptosis. pancreatic β cell apoptosis is also a pathological feature which is common in both type 1 ...

Mechanical stimulation is capable of affecting cell apoptosis. Several studies have shown that the Bcl-2 gene family, including and Bax gene, plays an important role in apoptosis, as proteins produced by can inhibit apoptosis while promote Understanding how mechanical alters expression apoptosis-related genes cardiomyocytes contribute to development ways cardiomyocyte necrosis. Intermediate myo...
