Hepatocyte growth factor (HGF) or scatter factor (SF) is a paracrine cellular growth, motility and morphogenic factor. It is secreted by mesenchymal cells and targets and acts primarily upon epithelial cells and endothelial cells , but also acts on haemopoietic progenitor cells and T cells .
Mutations in the HNF4A gene have been linked to maturity onset diabetes of the young 1 (MODY1). [ 8 ] This seems to be caused by HNF4-a's [1] role in the synthesis of SHBG , which is known to be severely diminished in patients with insulin-resistance .
Mutations in the HNF4A gene are associated with a form of diabetes called maturity onset diabetes of the young (MODY), [14] specifically MODY 1. At least 56 disease-causing mutations in this gene have been discovered. [15] Increased amplification of hepatocyte nuclear factor 4 alpha has been observed in colorectal cancer. [16]
Hepatocyte growth factor receptor (HGF receptor) [5] [6] is a protein that in humans is encoded by the MET gene.The protein possesses tyrosine kinase activity. [7] The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor.
HNF1 homeobox A (hepatocyte nuclear factor 1 homeobox A), also known as HNF1A, is a human gene on chromosome 12. [ 5 ] [ 6 ] [ 7 ] It is ubiquitously expressed in many tissues and cell types. [ 8 ] The protein encoded by this gene is a transcription factor that is highly expressed in the liver and is involved in the regulation of the expression ...
Forkhead box protein A2 (FOXA2), also known as hepatocyte nuclear factor 3-beta (HNF-3B), is a transcription factor that plays an important role during development, in mature tissues and, when dysregulated or mutated, also in cancer.
Hepatocyte nuclear factors (HNFs) are a group of phylogenetically unrelated transcription factors that regulate the transcription of a diverse group of genes into proteins. These proteins include blood clotting factors and in addition, enzymes and transporters involved with glucose , cholesterol , and fatty acid transport and metabolism .
Hepatocyte growth factor (HGF) is a mitogen and insulin tropic agent for the β cell. Inadequate β-cell mass can lead to insulin insufficiency and diabetes. During times of prolonged metabolic demand for insulin, the endocrine pancreas can respond by increasing β-cell mass, both by increasing cell size and by changing the balance between β ...
