Keratinocyte growth factor (KGF) is the seventh member of the fibroblast growth factor (FGF) family. It is produced by mesenchymal cells and its activity is specific for epithelial cell, controlling epithelial homeostasis and wound repair in a paracrine manner. Although KGF has been implicated in a number of hyperplastic pathologies, it has not previously been investigated in gingival hyperplasia (GH), an adverse side-effect of three pharmacologically different types of drugs, including the anti-hypertensive drug nifedipine (NIF), The mechanism by which NIF causes GH is not yet known, but we have recently shown that KGF mRNA transcripts are elevated in drug-induced GH in vivo (manuscript submitted). It is therefore possible that the action of NIF is mediated via KGF and, in the present study, using the enzyme-linked immunosorbent assay (ELISA) and the semi-quantitative reverse transcribed-polymerase chain reaction (RT-PCR), we found that NIF upregulates KGF secretion and gene transcription by gingival fibroblasts in vitro. Our results thus suggest that KGF may have an important role in the molecular pathology of GH in vivo. (C) 2000 Academic Press.
