The Present study attempts to determine the relationship between proliferation and inhibition of apoptosis in normal endometrium hyperplasia, using monoclonal antibodies against marker, Ki-67 anti-apoptotic protein, Bcl-2 expression B-cell lymphoma 2 (Bcl – 2) Ki 67 cyclical proliferative secretory phase. includes Bcl endometrial hyperplasia.

Fas/Apo-1 antigen (CD95) is a cell surface molecule that directly mediates apoptosis. Fas expression was studied in five plasma cell lines, 11 multiple myeloma cases, and three plasma cell leukemia (PCL) cases. Induction of apoptosis by anti-Fas antibody was studied in five plasma cell lines and fresh plasma cells from eight patients. Apoptosis was confirmed by morphologic analysis alone or in ...

it is widely thought that bcl-2 family proteins regulate commitment to apoptosis primarily through their capacity to control the permeability of the mitochondrial outer membrane permeabilization (momp) triggers the release of multiple apoptogenic factors into the cytosol and, thereby apoptosis. various bcl-2 family members affect this key event of the apoptotic cascade in different ways, determ...

Acute coronary syndromes (ACS) are precipitated by a rupture of the atherosclerotic plaque, often at the site of T cell and macrophage infiltration. Here, we show that plaque-infiltrating CD4 T cells effectively kill vascular smooth muscle cells (VSMC). VSMCs sensitive to T cell-mediated killing express the death receptor DR5 (TNF-related apoptosis-inducing ligand [TRAIL] receptor 2), and anti-...

Signal transducer and activator of transcription 3 (Stat3) and Myocardin regulate cardiomyocyte differentiation, proliferation, and apoptosis. We report a novel aspect of the cellular function of Myocardin and Stat3 in the regulation of cardiomyocyte apoptosis. Myocardin and Stat3 showed anti-apoptotic function by increasing the expression of Bcl-2 while reducing expression of the pro-apoptotic...

BACKGROUND Contrast-induced nephropathy (CIN) is the third leading cause of hospital-acquired acute renal failure. Oxidative stress, apoptosis and inflammation play crucial roles in CIN. Renalase is a newly discovered monoamine oxidase from the kidney. We hypothesize that renalase could protect against CIN through anti-oxidation, anti-inflammation and anti-apoptosis pathways. METHODS We teste...

Rheum turkestanicum Janischew. (Polygonaceae) is a plant that grows in central Asia and in north-east of Iran. Traditionally, people use roots of R. turkestanicum as an anti-diabetic and anti-hypertensive as well as anticancer agent. In this study the cytotoxicity and apoptogenic properties of ethyl acetate (EtOAc), n-hexane and H2O extracts from Rheum turkestanicum Janischew. (Polygonaceae) ro...

Black seed (Nigella sativa) is considered as a biological response modifier. Thymoquinone (TQ) is the bioactive and the most abundant constituent of the volatile oil of this seed which has been shown to possess anti-inflammatory, antioxidant and anti-neoplastic effects. In this study, the effect of TQ on HepG2 cell line was investigated in an attempt to identify its potential mechanism of actio...

Background: There is accumulating evidence that a polyphenol present in olive oil, oleuropein, has antioxidant, anti-inflammatory and anti-apoptotic effects. This study aimed at determining the anti-apoptotic effect of Oleuropein (Ole) on dexamethasone-induced apoptosis of mouse thymocytes. Method: Mice ...

Breast cancer is the most common malignancy in women worldwide. associated with a high mortality rate and health-related economic burden. patients have low 5-year life expectancy when diagnosed at advanced stages. Besides, emergence of chemoresistance breast has led to an intense search for alternative anticancer agents. One potential compounds Piperine. Several studies had found that Piperine ...
