Western blot analysis of caspase-12 and cleaved caspase-3 in pulmonary tissue homogenates in cchronic IH. Caspase-12 (a) and cleaved caspase-3 (b) were both up-regulated after 4 weeks of IH treatment. Western blot bands were normalized to β-actin. These effects were prevented by administration of TUDCA. (n = 4) . *P < 0.05; **P < 0.01; ns P > 0.05
