Peripheral insulin resistance contributes to the development of type 2 diabetes. TCF7L2 has been tightly associated with this disease, although the exact mechanism was largely elusive. Here we propose a novel role of TCF7L2 in hepatic glucose metabolism in mammals. Expression of medium and short isoforms of TCF7L2 was greatly diminished in livers of diet-induced and genetic mouse models of insu...

cytokines play a part in pathogenesis of periodontitis via inflammation phenomenon. aggressive periodontitis (agp) is a multifactorial disease resulting in rapid tooth loss due to severe destruction of tooth supporting apparatus. recently, researchers have focused on genetic susceptibility of periodontitis through investigating the gene variations of cytokines and other components of immune res...

Chondroitin sulphate (CS) is a natural glycosaminoglycan present in the extracellular matrix and is formed by the 1-3 linkage of D-glucuronic acid to N-acetylgalactosamine. In chondrocytes, CS diminishes interleukin-1 beta(IL-1beta)-induced increases in p38 mitogen-activated protein kinase (p38MAPK) and signal-regulated kinase 1/2 (Erk1/2) phosphorylation, and decreases nuclear factor-kappaB (N...

OBJECTIVES Zinc (Zn) deficiency often occurs in the patients with diabetes. Effects of Zn deficiency on diabetes-induced hepatic injury were investigated. METHODS Type 1 diabetes was induced in FVB mice with multiple low-dose streptozotocin. Hyperglycemic and age-matched control mice were treated with and without Zn chelator, N,N,N',N'-tetrakis (2-pyridylemethyl) ethylenediamine (TPEN), at 5 ...

BACKGROUND/AIMS Profibrogenic TGF-beta signaling in hepatic stellate cells is modulated during transdifferentiation. Strategies to abrogate TGF-beta effects provide promising antifibrotic results, however, in vivo data regarding Smad activation during fibrogenesis are scarce. METHODS Here, liver fibrosis was assessed subsequent to bile duct ligation by determining liver enzymes in serum and c...

Cytoprotective gene heme oxygenase 1 (HO-1) could be induced by nuclear factor E2-related factor 2 (Nrf2) nuclear translocation. The purpose of this study was to determine the role of Brahma-related gene 1 (Brg1), a catalytic subunit of SWI2/SNF2-like chromatin remodeling complexes, in Nrf2/HO-1 pathway activation during hepatic ischemia-reperfusion (HIR). Our results showed that hepatic Brg1 w...

1. The concentration in plasma of fibrinogen derivatives fibrinopeptide A (FPA) and B beta 1-42 and the platelet release products beta-thromboglobulin (beta TG) and platelet factor 4 (PF4) have been determined in patients with acute and chronic liver disease. 2. In 21 patients with fulmiant hepatic failure on admission in grade III or IV coma the plasma FPA, B beta 1-42, beta TG and PF4 levels ...

During fetal development, paired/homeodomain transcription factor Pax4 controls the formation of the insulin-producing beta cells and the somatostatin-producing delta cells in the islets of Langerhans in the pancreas. Targeting of Pax4 expression to the islet lineage in the fetal pancreas depends on a short sequence located approximately 2 kb upstream of the transcription initiation site of the...

Members of the platelet-derived growth factor (PDGF) ligand family are known to play important roles in wound healing and fibrotic disease. We show that both transient and stable expression of PDGF-C results in the development of liver fibrosis consisting of the deposition of collagen in a pericellular and perivenular pattern that resembles human alcoholic and nonalcoholic fatty liver disease. ...
