Repression of Human Fibroblast Growth Factor 2 by a Novel Transcription Factor

Repression of human fibroblast growth factor 2 by a novel transcription factor.

Here we describe the cloning of the regulator of fibroblast growth factor 2 (FGF-2) transcription (RFT) using a yeast one-hybrid screening with a defined motif in FGF-2 promoter as a target sequence. Overexpression of human RFT (RFT-A) reduces FGF-2 RNA and protein levels in both normal and tumor cell lines. Its splice variants, RFT-A' and RFT-B, have deletions in the putative DNA binding domai...

Fibroblast Growth Factor-1 vs. Fibroblast Growth Factor-2 in Ischemic Skin Flap Survival in a Rat Animal Model

BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...

Fibroblast Growth Factor 2 Direct Regulation of Rrna Transcription By

Direct regulation of rRNA transcription by fibroblast growth factor 2.

Fibroblast growth factor 2 (FGF-2), which is highly expressed in developing tissues and malignant cells, regulates cell growth, differentiation, and migration. Five isoforms (18 to approximately 34 kDa) of FGF-2 are derived from alternative initiation codons of a single mRNA. The 18-kDa FGF-2 isoform is released from cells by a nonclassical secretory pathway and regulates gene expression by bin...

crouzon syndrome: a fibroblast growth factor receptor 2 gene mutation

crouzon syndrome is a rare autosomal dominant premature cranyosynostosis, caused by fibroblast growth factor receptor 2 gene mutation on chromosome 10. the predominant skull and facial malformations with potential compromise airway make the crouzon syndrome a demanding issue for anesthesiologists and surgeons, required dynamic team work. in this report we describe a child, a known case of crouz...
