Gastric cancer (GC) is regarded as the fifth most common cancer and the third cause of cancer-related deaths worldwide. Mechanism of GC pathogenesis is still unclear and relies on multiple factors, including environmental and genetic characteristics. One of the most important environmental factors of GC occurrence is infection with Helicobacter pylori that is classified as class one carcinogens...
interferons (ifns) are a family of small regulatory glycoproteins that play a central role in the defense against viral infections. although ifns have been initially discovered as antiviral factors, today they are known as an integral part of the cytokine network that affect a wide range of biological processes. ifns exert their pleiotropic effects through their multisubunit cell surface recept...
The signaling pathways that depend on p53 or NFκB transcription factors are essential components of cellular responses to stress. In general, p53 is involved in either activation of cell cycle arrest or induction of apoptosis, while NFκB exerts mostly anti-apoptotic functions; both regulatory pathways apparently interfere with each other. Here we aimed to analyze the effects of NFκB activation ...
Hepatocellular carcinoma is the fourth cause of death due to cancer and includes 90% liver tumors. Therefore, in this study, it was tried show that Althaea officinalis L. flower extract (ALOF) can protect hepatocytes against N-diethylnitrosamine (DEN)-induced hepatocellular carcinoma. Totally, 70 Wistar rats were divided into seven groups (n = 10/group) sham, DEN, treatment with silymarin (SIL;...
Recently we demonstrated that mechanical stress induces apoptosis of vascular smooth muscle cells in vitro and in vein grafts (Mayr et al. FASEB J. 2000;15:261-270). The current study was designed to investigate molecular mechanisms of mechanical stretch-induced apoptosis. Smooth muscle cells cultivated on silicone elastomer plates precoated with collagen I, elastin, laminin, or Pronectin were ...
The p53 tumor suppressor is a tetrameric transcription factor that is posttranslational modified at -1 8 different sites by phosphorylation, acetylation, or sumoylation in response to various cellular stress conditions. Specific posttranslational modifications, or groups of modifications, that result from the activation of different stress-induced signaling pathways are thought to modulate p53 ...
The aim of the present study was to identify the common molecular mechanisms of multiple glioma subtypes, including astrocytoma, glioblastoma and oligodendroglioma, in addition to the specific mechanisms of different types. The gene expression profile set GSE4290 was downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) from three types of glioma, relative ...
Tumor-adjacent normal (TAN) tissues, which constitute tumor microenvironment and are different from healthy provide critical information at molecular levels that can be used to differentiate aggressive tumors indolent tumors. In this study, we analyzed 52 TAN samples the Cancer Genome Atlas (TCGA) prostate cancer patients developed a 10-gene prognostic model accurately predict biochemical recur...
