background noise pollution causes of apoptosis in germinal cells of testes. this study investigated the effects of honey and vitamin e administration on the process of apoptosis in cells of the germinal testis of rats exposed to noise stress. material and methods in this study, 24 male wistar rats randomly grouped as: 1 (honey + noise stress), 2 (vitamin e + noise stress) 3 (noise stress) and g...

Purpose: To investigate the therapeutic role of diosmetin in periodontitis and its probable mechanism action.Methods: Lipopolysaccharide (LPS) was used to induce periodontal cells. Cell viability apoptosis response LPS were evaluated using MTT TUNEL assays. The oxidative stress inflammatory responses LPS-induced effects cells detected enzyme-linked immunosorbent assay (ELISA). In addition, role...

The pharmacological role of garlic in prevention and treatment of cancer has received increasing attention, but thorough investigations into the molecular mechanisms of action of garlic compounds are rare. The present study demonstrates that ajoene, a major compound of garlic induces apoptosis in human leukemic cells, but not in peripheral mononuclear blood cells of healthy donors. The effect w...

objective(s) cigarette and nicotine enhances embryogenesis, fertility, pregnancy loss and ultrastructure alterations of oocyte. this study was performed to determine the effect of daily supplementation of vitamin e on oocytes apoptosis in nicotine-treated mice. materials and methods in this experimental study, 24 nmari adult female mice were randomly allocated into four experimental groups. for...

Although pyrimethamine (Tindurin™) appears to be effective in the prevention and treatment of some infectious diseases, very little information exists on its unpredictable properties. We design this study to evaluate its anti-tumoral effect on a model of cell line. Methods: The cytotoxic influence of Pyrimethamine on prostate cell line was investigated using an in vitro colometric assay. The po...

Butyrate, a fermentation product of the large bowel microflora, is potentially protective against the development of colorectal cancer. In vitro, butyrate has been shown to induce apoptosis and inhibit proliferation in numerous cancer cell lines, including colorectal cancer. Although these tumor suppressing properties of butyrate are well-documented in experimental systems, the mechanisms under...

These studies report on the activation and induction of cGMP-dependent protein kinase (PKG) by exisulind and analogs and test the hypothesis that PKG is involved in the induction of apoptosis in colon tumor cells. Exisulind and analogs are proapoptotic drugs developed as inhibitors of cGMP phosphodiesterase gene families 5 and 2 that have been shown to sustain increased cGMP in SW480 and HT29 c...

Abstract Background Long non-coding RNA is considered to be essential modulate the development and progression of human malignant cancers. And long can act as crucial modulators by sponging corresponding microRNA in tumorigenesis. We aimed elucidate function ACTA2-AS1 its molecular mechanism colon adenocarcinoma. Materials methods The expression ACTA2-AS1, miR-4428 BCL2L11 adenocarcinoma tissue...

We previously reported that the garlic-derived compound S-allylmercaptocysteine (SAMC) causes growth inhibition, mitotic arrest, and induction of apoptosis in SW480 human colon cancer cells by inducing microtubule depolymerization and c-Jun NH(2) terminus kinase-1 activation. In the present study, we compared the aforementioned effects of SAMC to those of a series of garlic-derived and other or...

The electrophoresis pattern of apoptotic cells detected by the comet assay has a characteristic small head and spread tail. This image has been referred to as an apoptotic comet, but it has not been previously proven to be apoptotic cells by any direct method. In order to identify this image obtained by the comet assay as corresponding to an apoptotic cell, the frequency of appearance of apopto...
