Both protein phosphatase-1 (PP-1) and PP-2A inhibit cAMP-mediated increases in transcription by dephosphorylating CREB at ser-133. Western blot analysis indicated that protein phosphatase 1 (PP-1) was expressed constitutively in palatal tissue during its development. Expression of PP-2A was regulated developmentally with maximal expression on gestational day (gd) 14. Densitometric scanning revealed a 30% increase in expression from gd 13 to gd 14. Virtually all phosphatase activity in the tissue extracts could be inhibited by 5 microM okadaic acid, demonstrating that PP-1 and PP-2A account for all detectable ser/thr protein phosphatase activity present in the developing palate. Moreover, no significant differences in PP-1 and PP-2A activities were observed during the period of palate development. Treatment of primary cultures of murine embryonic palate mesenchymal (MEPM) cells with forskolin (20 microM) to elevate intracellular cAMP levels, resulted in a time-dependent increase in CREB ser-133 phosphorylation and a corresponding time dependent decrease in PP-1 and PP-2A levels. Moreover, treatment of MEPM cells with okadaic acid resulted in a dramatic increase in basal CREB ser-133 phosphorylation. This suggests that PP-1 activity may contribute to transcriptional regulation of CREB and that PP-1 and PP-2A are regulated differentially by cAMP. Treatment of MEPM cells with TGF beta 1 (1 ng/ml) under conditions of TGF beta-induced CREB phosphorylation resulted in no effect on the expression of either PP-1 or PP-2A proteins and no significant alterations in total basal protein phosphatase activity. These results demonstrate that transcriptional regulation of CREB in embryonic palatal issue is dependent on the coordinate activity of specific kinases and phosphatases."xsd:string |
