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 ...
Background: In this study, the protective effect of thymoquinone (TQ) and Nigella sativa seeds oil (NSO) was evaluated against oxidative damages induced by ethanol in rats. Methods: Animals were treated with ethanol 40% daily by gavages once a day for 4 weeks. NSO and TQ were injected intraperitoneal once a day for 4 weeks. The histopathological examination of liver, kidney, brain and heart was...
Background & Aim: Evidence suggests that apoptosis plays an important role in the aging process. Today, regular physical activity is recognized as a defense strategy in delaying aging and related diseases. This study aimed to evaluate the effect of 12 weeks of resistance training on serum levels of p53, caspase-3, and caspase-9 in sedentary elderly men. Methods: In this quasi-experimental stud...
objective(s): menopause and diabetes obviously increase the risk of cardiovascular disease in women. the aims of the present study were to evaluate the effects of ovariectomy in type 2 diabetes on the histology and expression of mirna-29, mirna-133, igf-1 and bcl-2 genes and bcl-2 protein and caspase 3 activity in the hearts of female rats. materials and methods: forty female wistar rats were d...
background micrornas are small and non-coding rna molecules with approximately 22 nt in length that cause inhibition of translation or degradation of mrna. mir-155 is a kind of molecule with different functions, such as its role in proliferation, apoptosis, inflammation, differentiation, and immunity. one of its best known functions is apoptosis that affects on caspase-3 activity. the main aim ...
soybean isoflavone genistein has multiple anticancer properties and its pro-apoptotic and anti-proliferative effects have been studied in different cancer cells. however, the mechanisms of action of genistein and its molecular targets on human colon cells have not been fully elucidated. therefore, caspase-3 and p38 mitogen-activated protein kinase (p38 mapk) as the main therapeutic targets were...
objective(s): protein kinase c (pkcα) is involved in modulating articular chondrocytes apoptosis induced by nitric oxide (no). hyaluronic acid (ha) inhibits nitric oxide-induced apoptosis of articular chondrocytes by protecting pkcα, but the mechanism remains unclear. the present study was performed to investigate the effects and mechanisms of pkcα regulate protective effect of hyaluronic acid....
objective(s): juglone is isolated from many species of the juglandaceae family and used as an anti-viral, anti-bacterial, and anti-tumor therapeutic. here, we evaluated juglone-induced antitumor effect in ovarian cancer skov3 cells. materials and methods: mtt assay was performed to examine juglone anti-proliferative effect. cell cycle and apoptosis were studied using flow cytometry in juglone-tr...
cladribine, an analogue of deoxyadenosine, is highly toxic for both non-dividing and proliferating cells and has shown activity in the treatment of several malignancies. therefore, the aim of the present study is to investigate the cytotoxicity effect of cladribine (2-cda) on the breast cancer cell line, mcf-7 (estrogen receptor positive, er+). mtt assay, annexin v-fluorescein/pi and hoechst 33...
Hexameric hemoprotein (HTHP) is employed as a scaffold protein for the supramolecular assembly and activation of apoptotic signalling enzyme caspase-9, using short DNA elements modular recruitment domains. Caspase-9 on HTHP platform due to enhanced proximity followed by combinatorial inhibition at high concentrations. The domains allow reversible switching caspase-9 activity state modulatory st...
