Protein kinase C is not involved in the homologous desensitization of bombesin responses in small cell lung cancer cells.

Abstract:

:Homologous desensitization of responses to bombesin in small cell lung cancer cells can be mimicked by protein kinase C-activating phorbol esters. We show that phorbol ester-induced desensitization can be blocked by prior treatment with the protein kinase C inhibitor staurosporine or prolonged pretreatment with phorbol esters. However, under these conditions, homologous desensitization to bombesin persists. These data indicate that phorbol ester-induced desensitization is distinguishable from bombesin-induced homologous desensitization. Protein kinase C is not a dominant component in the homologous desensitization to bombesin in small cell lung cancer cells.
