background resistance exercise is recommended as a useful therapeutic tool for the treatment of type 2 diabetes (t2d); however, the frequency of studies is inadequate to establish the precise mechanisms of any association between them. objectives in this study, we aimed to assess the effect of three months of resistance training on tcf7l2 expression in pancreatic tissues, serum insulin and gluc...
Certain single nucleotide polymorphisms (SNPs) in transcription factor 7-like 2 (TCF7L2) are strongly associated with the risk of type 2 diabetes. TCF7L2 and β-catenin (β-cat) form the bipartite transcription factor cat/TCF in stimulating Wnt target gene expression. cat/TCF may also mediate the effect of other signaling cascades, including that of cAMP and insulin in cell-type specific manners....
Introduction: Both environmental and genetic factors have been implicated in the development of type 2 diabetes (T2D). The objectives of the present study were: 1) to investigate the effect of high intensity interval training (HIIT) on fasting glucose, insulin and TCF7L2 expression in pancreas tissue of T2D rats, 2) to determine the relation between TCF7L2 expression with insulin changes in the...
OBJECTIVE Polymorphisms in the human TCF7L2 gene are associated with reduced insulin secretion and an increased risk of type 2 diabetes. However, the mechanisms by which TCF7L2 affect insulin secretion are still unclear. We define the effects of TCF7L2 expression level on mature beta-cell function and suggest a potential mechanism for its actions. RESEARCH DESIGN AND METHODS TCF7L2 expression...
In the liver Wnt-signaling contributes to the metabolic fate of hepatocytes, but the precise role of the TCF7L2 in this process is unknown. We employed a temporal RNA-Seq approach to examine gene expression 3-96 h following Tcf7l2 silencing in rat hepatoma cells, and combined this with ChIP-Seq to investigate mechanisms of target gene regulation by TCF7L2. Silencing Tcf7l2 led to a time-depende...
Genetic studies have linked the risk of Type 2 diabetes with SNPs (single nucleotide polymorphisms) in the gene encoding the Wnt signalling-associated transcription factor, TCF7L2 (T-cell factor 7-like 2). The risk alleles have been associated with reduced glucose and GLP-1 (glucagon-like peptide 1)-stimulated insulin secretion. Recent evidence has suggested that inheritance of the at-risk T al...
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...
Vaquero AR, Ferreira NE, Omae SV, Rodrigues MV, Teixeira SK, Krieger JE, Pereira AC. Using gene-network landscape to dissect genotype effects of TCF7L2 genetic variant on diabetes and cardiovascular risk. Physiol Genomics 44: 903–914, 2012. First published August 7, 2012; doi:10.1152/physiolgenomics.00030.2012.—The single nucleotide polymorphism (SNP) within the TCF7L2 gene, rs7903146, is, to d...
The transcription factor T-cell factor 7-like 2 (TCF7L2) confers type 2 diabetes risk mainly through impaired insulin secretion, perturbed incretin effect and reduced beta-cell survival. The aim of this study was to identify the molecular mechanism through which TCF7L2 influences beta-cell survival. TCF7L2 target genes in INS-1 cells were identified using Chromatin Immunoprecipitation. Validati...
OBJECTIVE The WNT signaling pathway effector gene TCF7L2 has been associated with an increased risk of type 2 diabetes. However, it remains unclear how this gene affects diabetic pathogenesis. The goal of this study was to investigate the effects of Tcf7l2 haploinsufficiency on metabolic phenotypes in mice. EXPERIMENTAL DESIGN Tcf7l2 knockout (Tcf7l⁻/⁻) mice were generated. Because of the ear...
