[ 1 ] - Truncated forms of RUNX3 unlike full length protein alter cell proliferation in a TGF-β context dependent manner

The Runt related transcription factors (RUNX) are recognized as key players in suppressing or promoting tumor growth. RUNX3, a member of this family, is known as a tumor suppressor in many types of cancers, although such a paradigm was challenged by some researchers. The TGF-β pathway governs major upstream signals to activate RUNX3. RUNX3 protein consists of several regions and domains. The Ru...

[ 2 ] - Blood concentrations of cadmium and lead in multiple sclerosis patients from Iran

Since industrial revolution heavy metals such as lead (Pb) and cadmium (Cd) have been extensively dispersed in environment which, unknown biological effects and prolong biological half-life make them as a major hazard to human health. In addition, the sharp increase in Multiple sclerosis incidence rates has been recorded in Iran. The propose of this study was to measuring blood lead and cadmium...

[ 3 ] - Celecoxib Treatment Alters p53 and MDM2 Expression via COX-2 Crosstalk in A549 Cells

Cyclooxygenase-2 (COX-2) has a pivotal role in the pathogenesis of the lung cancer. It is known that COX-2 negatively regulates the activity of a number of tumor suppressors, including p53. Consequently, inhibition of COX-2 signaling is anticipated to be a promising approach to stabilize p53 functionality. In this regard, we investigated the effect of COX-2 signaling blockade on p53 and COX-2 e...

[ 4 ] - Correlation between Cigarette Smoking and Urine Cotinine Level in Gastric Cancer Patients

Various substances in cigarette smoke including nicotine have been shown to promote/induce cancer cell proliferation. Since cotinine has a longer half life and stability in the blood, it has become the preferred biomarker for cigarette smoking exposure. Seventy-three gastric cancer patients were included in this study. The tumor tissues were stained with H and E for pathological evaluation. The...

[ 5 ] - Runx3 Expression Inhibits Proliferation and Distinctly Alters mRNA Expression of Bax in AGS and A549 Cancer Cells

Runx3, a member of Runt-related transcription factor (Runx) proteins with tumor suppressor effect, is a tissue–restricted and cancer related transcription factor that regulate cell proliferation and growth, as well as differentiation. In the present study, exogenous Run3 was transiently expressed in AGS (human gastric adenocarcinoma), with undetectable Runx3 protein and in A549 (human lung carc...
