Neural stem/progenitor cells (NSPCs) give rise to billions of cells during development and are critical for proper brain formation. The finding that NSPCs persist throughout adulthood has challenged the view that the brain has poor regenerative abilities and raised hope for stem cell-based regenerative therapies. For decades there has been a strong movement towards understanding the requirement...

Regucalcin (RGN/SMP30) and its gene (rgn)are identified in over 15 species consisting of regucalcin family, and its gene is localized on X chromosome. Regucalcin has been shown to play a multifunctional role in many tissues and cell types. Hormonal regulations of regucalcin gene expression are mediated through various transcription factors (including AP-1, NF1-A1, RGPR-p117 and other), which ar...

Cancer cells re-program their metabolic machinery in order to satisfy their bioenergetic and biosynthetic requirements. A critical aspect of the re-programming of cancer cell metabolism involves changes in the glycolytic pathway (referred to as the "Warburg effect"). As an outcome of these changes, much of the pyruvate generated via the glycolytic pathway is converted to lactic acid, rather tha...

T he vascular endothelium, the major interface of the vessel wall between blood and all tissues, must constantly adapt to fluctuations in environmental cues. Cellular metabolism is one mechanism that may contribute to rapid dynamic changes in cell phenotype. For example, glycolysis, one of the major forms of cellular metabolism that converts glucose to pyruvate, is required for immune cell acti...

total protein and dna extracted from histologically diagnosed normal nonmalignant and esophageal tumor tissues were used for analysis of polypeptides pattern by two-dimensional gel electrophoresis and dna transforming activity in nih 3t3 cell transfection assay, respectively. in comparison to normal tissues, eight polypeptides underwent down-regulation or disappeared, while seven polypeptides w...

The present study was conducted to test the effect of Origanum Majoranum Extract (OME) of leaves on alterations induced in a model of type 2 diabetic rats. Adult male Wistar rats were fed high fat diet for 3 weeks and injected a single dose of streptozotocin (35 mg/kg) intraperitoneally to induce type 2 diabetic rats. Diabetic rats were given aqueous extract of OME in a dose of 20 mg/kg orally ...

Analysis of genetically engineered mice deficient in cell cycle regulators, including E2F1, cdk4, and pRB, showed that the major phenotypes are metabolic perturbations. These key cell cycle regulators contribute to lipid synthesis, glucose production, insulin secretion, and glycolytic metabolism. It has been shown that deregulation of these pathways can lead to metabolic perturbations and relat...
