Introduction: Gastric cancer is the fourth common cancer and the second leading cause of death from cancer worldwide. Omega fatty acids are a group of non-saturated fatty acids of long chains derive from linolenic, linoleic and oleic fatty acids. The current study aimed at examining the possible effects of oral administration of omega-3, -6 and -9 fatty acids on gastric cancer cell apoptosis in...

The tumor suppressor gene p53 regulates G1 checkpoint prior to the initiation of DNA synthesis, which can either induce G1 arrest or signal apoptosis. The involvement of p53 in apoptosis may also be related to its ability to down-regulate transcription of the bcl-2 gene. The bcl-2 gene product prevents most types of apoptotic cell death, suggesting that bcl-2 interferes with an essential signal...

Recently, we have shown that the p53 tumor suppressor gene product can inhibit expression of the bcl-2 gene. In this report, we explored the molecular basis for p53-mediated down-regulation of bcl-2 gene expression using a cotransfection approach involving p53 expression plasmids and chloramphenicol acetyltransferase (CAT) reporter gene constructs containing regions from the bcl-2 gene. When tr...

In most human follicular lymphomas, the chromosome translocation t(14;18) occurs within two breakpoint clustering regions on chromosome 18, the major one at the 3' untranslated region of the bcl-2 gene and the minor one at 3' of the gene. Analysis of a panel of follicular lymphoma DNAs using probes for the first exon of the bcl-2 gene indicates that DNA rearrangements may also occur 5' to the i...

Background: BCL-2 is the most important anti-apoptotic regulator and Bax is a pro-apoptotic protein. The status of these parameters or the ration of BCL-2 to BAX is important in malignant cell fate as well as normal cells. Methods: Sixty-two ALL patients and 62 healthy sex-and age-matched controls were studied. After genotyping, the promoter region of the BAX and BCL-2 genes by RFLP-PCR meth...

This study aims to explore the cytotoxic, apoptotic and autophagic effects of thymoquinone on human acute myeloid leukemia. The cytotoxic were determined with 3-(4, 5-dimethylthiazol-2-yl)-2 5-diphenyltetrazolium bromide (MTT) tests. B-cell lymphoma 2 associated X protein (Bax), (Bcl-2), caspase 3, mammalian target rapamycin (mTOR), phosphatidylinositol-3-kinase (PI3K), kinase B (AKT) gene expr...

Backgrounds: Hepatocellular carcinoma (HCC), Primary liver cancer, is the fifth most common cancer in men. Histone deacetylation causes chromatin condensation resulting gene silencing and tumorigenesis. These enzymes have become a novel target for treatment of cancer. deacetylase inhibitors (HDACIs) can reactivate tumor suppressor genes (TSGs) by inhibition histone deacetylases (HDACs) activity...
