Effect of cholecystokinin octapeptide on tumor necrosis factor-α-induced proliferation of RSC-364 cells and secretion of matrix metalloproteinases as well as relevant mechanism
Objective To investigate the influence of cholecystokinin octapeptide(CCK-8) on tumor necrosis factor-α(TNF-α)-induced proliferation of RSC-364 cells and secretion of matrix metalloproteinases(MMPs) as well as the relevant mechanism. Methods The proliferation of RSC-364 cells induced by TNF-α was measured by monotetrazolium(MTT) colourmetric assay, while the secretion levels of MMP-1, MMP-3 and MMP-9, cyclic adenosine monophosphate(c AMP) content and protein kinase A(PKA) activity were determined by ELISA. ...
