1 The regulation of protein kinase C (PKC) isoforms by ceramide is still controversial. Ceramides protein kinase C alpha Homo sapiens
2 In this work, the yeast Saccharomyces cerevisiae was used as a model to elucidate the effect of ceramide on the activity of mammalian PKC isoforms. Ceramides protein kinase C alpha Homo sapiens
3 Moreover, using a yeast-based assay previously developed for the screening of PKC inhibitors, it was also shown that, like the known PKC inhibitor NPC 15437, ceramide reduced the PMA-induced growth inhibition, supporting an inhibitory effect of ceramide on PKCdelta. Ceramides protein kinase C alpha Homo sapiens
4 Moreover, using a yeast-based assay previously developed for the screening of PKC inhibitors, it was also shown that, like the known PKC inhibitor NPC 15437, ceramide reduced the PMA-induced growth inhibition, supporting an inhibitory effect of ceramide on PKCdelta. Ceramides protein kinase C alpha Homo sapiens
5 Altogether, these results may indicate that ceramide distinctly interfere with the activity of PKCalpha, delta and zeta. Ceramides protein kinase C alpha Homo sapiens
