The present study was addressed to understand the interrelationship between
Receptor-C-k induction-activation coupling; isoprenoids (derived from meva
lonate pathway) and cyclin-dependent kinase inhibitors. The results reporte
d here unambiguously reveal that isoprenoids regulate the expression of gen
es coding for CDK inhibited p16 and p27. Further, Receptor-C-k dependent si
gnalling, known to control the mevalonate pathway, had a direct effect upon
the p27 gene expression. Based upon these studies coupled with our earlier
findings we propose that Receptor-C-k has an important role in the regulat
ion of cell cycle machinery.
