Effects of anti-CRT on the levels of p38, p-p38, p65 and p-p65 protein. (A) Representative western blot bands for p38, p-p38, p65 and p-p65. Relative protein levels of (B) p/t-p38 and (C) p/t-p65. GAPDH was used as an internal reference. ##P<0.01 vs. NC; **P<0.01 vs. SP-A group. SP-A, surfactant protein A; CRT, calreticulin; NC, normal control; p-p38, phosphorylated p38; p-p65, phosphorylated p65.
