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

Figure 3 sCCK-8 increased IκB α protein level at 30 min after LPS stimulation in a dose-dependent manner in PIMs. A: Representative Western blot of three experiments. B: Normalized total protein of IκBα immunoreactivity. n = 3, ¯x ± s, ^aP > 0.05, ^bP < 0.05, ^cP < 0.01 vs control; ^dP > 0.05, ^eP < 0.05, ^fP < 0.01 vs LPS; ^hP < 0.05 vs LPS + CCK 10^-7 mol·L^-1.
