Rapid increase of inositol 1,4,5-trisphosphate in the HeLa cells after hypergravity exposureThe IP3 level in HeLa cells has been elevated through the application in hypergravity in a time-dependent manner. The data obtained for the hydrolytic products of PIP2, IP3, and DG are noted to modulate c-myc gene expression. It is also established that the cAMP accumulation by the IBMX in hypergravity-exposed cells was suppressed relative to the control. In light of IP3 increase and cAMP decrease results, a single GTP-binding protein may play a role in the hypergravity signal transduction of HeLa cells by stimulating PLC while inhibiting adenylate cyclase.
