title: Basic fibroblast growth factor and keratinocyte growth factor over-expression in benign prostatic hyperplasia.
abstract: The prostate growth is under the indirect control of androgens through the medium of many growth factors. The fibroblast growth factors (FGFs) seem to play an important part in stimulating the development of this organ. In this work, the expression of two FGFs: bFGF (or FGF2) and KGF (or FGF7), was studied in RT-PCR and semi-quantified in densitometry. Both genes expression was increased in BPH in comparison with normal prostates. A two to three times and a 1.5 to four times over-expressions were observed for bFGF and KGF, respectively. An over-expression of these growth factors could lead to a cell multiplication resulting in a pathological development of the prostate size. Moreover, bFGF and KGF act in parallel in the prostate, one stimulating the prostatic stroma and the other one stimulating the epithelium. These two growth factors could participate in the increase of the two tissues constituting the prostate.
