Receptor-mediated endocytosis of keratinocyte growth factor.
Keratinocyte growth factor (KGF) is a fibroblast growth factor which acts specifically on epithelial cells, regulating their proliferation and differentiation. KGF elicits its activity through binding to and activation of KGF receptor, a splicing transcript variant of fibroblast growth factor receptor 2 (FGFR2). Here we analyzed the pathway of internalization of KGF and its receptor using sever...
متن کاملKeratinocyte growth factor receptor ligands induce transforming growth factor alpha expression and activate the epidermal growth factor receptor signaling pathway in cultured epidermal keratinocytes.
Epidermal growth factor receptor (EGFR) ligands are fundamental regulators of epithelial growth, differentiation, and neoplastic transformation. In addition to being potent mitogens for murine epidermal keratinocytes in vitro, transforming growth factor alpha (TGF alpha) and EGF elicit distinctive changes in keratin expression: Ca(2+)-mediated induction of the differentiation-specific keratins ...
متن کاملHepatocyte growth factor, keratinocyte growth factor, and other growth factor-receptor systems in the lens.
PURPOSE To examine the expression and function of hepatocyte growth factor (HGF), keratinocyte growth factor (KGF), epidermal growth factor (EGF) and other growth factor-cytokine-receptor systems in lens epithelial cells. METHODS Reverse transcription-polymerase chain reaction (RT-PCR) and Northern blot analysis were used to examine the expression of messenger RNAs in primary cultured rabbit ...

Dna2 was first characterized in yeast as an essential gene encoding a protein with both helicase and endonuclease activities involved in maturation of Okazaki fragments during DNA replication. Dna2 also plays a role in double-strand break (DSB) repair by homolo-gous recombination. The respective contributions of its replication and/or repair functions toward cell viability and resistance to gen...
