A few genetic polymorphisms of TP53 are known to have a significant effect on cancer susceptibility. Intron 3 16 bp duplication polymorphism of TP53 has been reported to be associated with breast cancer, colorectal cancer, lung cancer and other cancers, but the reported results remain inconclusive. The present study, a meta-analysis including a total of 9801 cases and 10,391 controls from 26 st...

BackgroundAttention deficit hyperactivity disorder (ADHD), is a multifactorial disorder and converging evidence has implicated abnormalities of dopamine neurotransmission. The aim of this study was to examine the association of -141 polymorphisms in DRD2 gene with ADHA among Iranian-Azeri population.Materials and Methods A case–control association study included 153 patients with attention defi...

Adenophostins A and B, which are metabolic products of the fungus Penicillium brevicompactum, are potent agonists at the D-myo-inositol-1,4,5-trisphosphate [Ins(1,4,5)P3] receptor. In the current study, adenophostin A was approximately 50-fold more potent than Ins(1,4,5)P3 at both releasing Ca2+ from the intracellular stores of permeabilized platelets and displacing [3H]Ins(1,4,5)P3 from its re...

We have previously found that for permeabilized L1210 cells, low micromolar concentrations of Ins(1,3,4,5)P % added prior to Ins(2,4,5)P $ enhance the effects of suboptimal concentrations of Ins(2,4,5)P $ in causing Ca#+ release from InsP $ -sensitive Ca#+ stores [Cullen, Irvine and Dawson (1990) Biochem. J. 271, 549–553]. If this was due either to some conversion of added Ins(1,3,4,5)P % into ...

BACKGROUND MDM2 (Murine Double Minute2) is an oncoprotein that inhibits the P53 activity. Overexpression of MDM2 gene has been reported in several human tumors. In the present study, we aimed to evaluate the impact of 40-bp insertion/deletion (ins/del) polymorphism on the promoter of MDM2 and susceptibility to breast cancer in a sample of Iranian population. METHODS This case-control study wa...

Whether hyperinsulinemia is required for stimulation of net hepatic glucose uptake (NHGU) by a selective serotonin reuptake inhibitor (SSRI) was examined in four groups of conscious 42-h-fasted dogs, using arteriovenous difference and tracer ([3-3H]glucose) techniques. Experiments consisted of equilibration (-120 to -30 min), basal (-30 to 0 min), and experimental periods (Exp; 0-240 min). Duri...

Human erythrocyte membranes metabolize inositol 1,3,4,5-tetrakisphosphate [Ins(1,3,4,5)P4] to inositol 1,3,4-trisphosphate [Ins(1,3,4)P3] in the presence of Mg2+. In the absence of Mg2+ a less rapid conversion of Ins(1,3,4,5)P4 into Ins(1,4,5)P3 was revealed. Such an enzyme activity, if present in hormonally sensitive cells, could provide a mechanism for maintaining constant concentrations of I...
