Mammalian cardiomyocytes have limited proliferation potential, and acutely injured mammalian hearts do not regenerate adequately. Instead, injured myocardium develops fibrosis and scarring. Here we show that FGF1/p38 MAP kinase inhibitor treatment after acute myocardial injury in 8- to 10-week-old rats increases cardiomyocyte mitosis. At 3 months after injury, 4 weeks of FGF1/p38 MAP kinase inh...
The phosphorylation state of pocket proteins during the cell cycle is determined at least in part by an equilibrium between inducible cyclin-dependent kinases (CDKs) and serine/threonine protein phosphatase 2A (PP2A). Two trimeric holoenzymes consisting of the core PP2A catalytic/scaffold dimer and either the B55α or PR70 regulatory subunit have been implicated in the activation of p107/p130 an...
Fibroblast growth factor (FGF) signaling begins with the formation of a ternary complex of FGF, FGF receptor (FGFR), and heparan sulfate (HS). Multiple models have been proposed for the ternary complex. However, major discrepancies exist among those models, and none of these models have evaluated the functional importance of the interacting regions on the HS chains. To resolve the discrepancies...
Background and purpose: Alzheimer’s disease (AD) is a neurodegenerative disorder which is the most common cause of dementia in elderly. Fibroblast growth factor 1(FGF1) selectively protects neurons against neurotoxic effects. This study aimed to evaluate the association between the G/A (rs34011) FGF1 gene polymorphism and Alzheimer’s disease in southwest of Iran. Materials and me...
Together with glial-derived neurotrophic factor (GDNF), soluble factors present in a metanephric mesenchyme (MM) cell conditioned medium (BSN-CM) are necessary to induce branching morphogenesis of the isolated ureteric bud (UB) in vitro (Proc. Natl. Acad. Sci. USA 96 (1999) 7330). Several lines of evidence are presented here in support of a modulating role for fibroblast growth factors (FGFs) i...
Recent evidence demonstrates that epigenetic regulation of gene transcription is critically involved in learning and memory. Here, we discuss the role of histone acetylation and DNA methylation, which are two best understood epigenetic processes in memory processes. More specifically, we focus on learning-strength-dependent changes in chromatin on the fibroblast growth factor 1 (Fgf1) gene and ...
Glioblastoma (GBM) is a highly malignant brain tumor. The GBM tumor mass contains a unique cell population, GBM stem cells (GBM-SCs), which possess the self-renewal, tumor initiating and tumor progression. FGF1B is the major transcriptional variant of FGF1 in GBM. In our recent study, we demonstrated the FGF1B transcript is up-regulated in self-renewing GBM cells. In order to study GBM-SCs, we ...
Fibroblast growth factor (FGF) signaling regulates mammalian development and metabolism, and its dysregulation is implicated in many inherited and acquired diseases, including cancer. Heparan sulfate glycosaminoglycans (HSGAGs) are essential for FGF signaling as they promote FGF.FGF receptor (FGFR) binding and dimerization. Using novel organic synthesis protocols to prepare homogeneously sulfat...
BACKGROUND Recent studies suggest that betaKlotho (KLB) and endocrine FGF19 and FGF21 redirect FGFR signaling to regulation of metabolic homeostasis and suppression of obesity and diabetes. However, the identity of the predominant metabolic tissue in which a major FGFR-KLB resides that critically mediates the differential actions and metabolism effects of FGF19 and FGF21 remain unclear. METHO...
Branching morphogenesis of mouse submandibular glands is regulated by multiple growth factors. Here, we report that ex vivo branching of intact submandibular glands decreases when either FGFR2 expression is downregulated or soluble recombinant FGFR2b competes out the endogenous growth factors. However, a combination of neutralizing antibodies to FGF1, FGF7 and FGF10 is required to inhibit branc...
