Effect of cholecystokinin octapeptide on tumor necrosis factor α transcription and nuclear factor-κB activity induced by lipopolysaccharide in rat pulmonary interstitial macrophages

Figure 1 sCCK-8 inhibited LPS-induced TNF-α mRNA expression in PIMs in a dose-dependent manner. A: Representative pictures of three experiments of RT-PCR. B: Relative level of TNF-α mRNA expression. n = 3, ¯x ± s, ^aP > 0.05, ^cP < 0.01 vs control, ^eP < 0.05, ^fP < 0.01 vs LPS.
