P. Janik et al., THE EFFECT OF PHORBOL ESTER TREATMENT ON MIGRATION OF C3H 10T1 2 AND BT5C GLIOMA-CELLS - POSSIBLE APPLICATION TO CARCINOGENESIS/, Journal of cancer research and clinical oncology, 120(3), 1994, pp. 156-158
Treatment with the tumor-promoting phorbol ester 12-O-tetradecanoylpho
rbol 13-acetate (TPA) and the second-stage promotor 12-O-retinoylphorb
ol 13-acetate induced down-regulation of protein kinase C (PKC) and en
hanced the migration of C3H 10T1/2 cells. In the case of BT5C glioma c
ells the same negative correlation was observed only after treatment w
ith TPA. The negative control 4alpha-phorbol affected neither PKC acti
vity nor the migratory ability of both cell lines.
