9、1.7 nM (EC50)體外研究 In order to examine the role of PKC in p38MAPK phosphorylation, the cells are stimulated with the PKC activator,PMA (100 nM), which mimics the binding of DAG, the natural activator of PKC, to the C1 region of the PKCs.p38MAPK phosphorylation by PMA is observed in the two cell types

10、 similar to that observed by GnRH in T3-1 cells,that is, a slow sustained activation (3.2-fold and 3.6-fold, respectively at 30 min). The paradoxical findings that PKCsactivated by GnRH and PMA play a differential role in p38MAPK phosphorylation may be explained by differentiallocalization of the PK

11、Cs. Basal, GnRH- and PMA- stimulation of p38MAPK phosphorylation in T3-1 cells is mediatedby Ca2+ influx via voltage-gated Ca2+ channels and Ca2+ mobilization, while in the differentiated LT2 gonadotropecells it is mediated only by Ca2+ mobilization2.體內(nèi)研究 PMA is a PKC agonist, which reverses the dam

Thus, activation of themitoKATP protected mitochondrial function in SOD and MDA via the PKC pathway3.PROTOCOLCell Assay 2 T3-1 and LT-2 cells are grown in monolayer cultured in DMEM in humidified incubator 5% CO2 at 37C. Serumstarvation is with 0.1% FCS

13、in the same medium for 16 h. GnRH and PMA are then added for the length of time asPage 2 of 3 www.MedChemEindicated. In general, T3-1 cells are transiently transfected by ExGen 500 or by jetPRIME, while LT2 cells only byjetPRIME transfection reagent. For experiments with dominant-negative (DN) PKCs,

14、 T3-1 cells (in 6 cm plates) aretransfected with 1.5 g of p38-GFP with 3 g of control vector, pCDNA3, or with 3 g of the DN-PKCs constructs.For LT2 cells, transfections are performed (in 10 cm plates) with 4 g of p38-GFP along with 9 g of control vector,pCDNA3, or with 9 g of the DN-PKCs constructs.

15、 Approximately 30 h after transfection, the cells are serum starved(0.1% FCS) for 16 h and later stimulated with GnRH or PMA, washed twice with ice-cold PBS, treated with the lysisbuffer, followed by one freeze-thaw cycle. Cells are harvested; following centrifugation (15,000g, 15 min, 4C)supernatan
