Based on preceding experiment, we further studied the co-regulative effects of PKA-R II and PKC-alpha on expression of oncogenes in human gastric cell line MGC 80-3. The c-myc and c-H-ras expression were suppressed in MGC 80-3 cells during HMBA-induced differentiation. At the same time, PKA-R II showed nuclear translocation from cytoplasm, whereas the expression of PKC-alpha shifted from nucleus to cytoplasm. PKA inhibitor (Sigma) was added to block cAMP-PKA pathway when cell differentiation were induced by HMBA. The PKA-R II was still located in cytoplasm but expression of PKC-alpha translocated again into nucleus. Meanwhile, the c-myc and c-H-ras again expressed. This suggested that the changing regulation of oncogene expression were closely related to signalling from nuclear translocation of kinase subspecies. It thus shows the co-regulation effects of two signal system on oncogenes expression.
