Relative expression of autophagic proteins in human lung tissues.

Table 1 shows the quantified Western blot analysis of Autophagy-related proteins, LC3-II/LC3-I, Atg4, Atg5-atg12 and Atg7, in human lung tissues from normal patients, from various stages of COPD (GOLD0, GOLD2, GOLD3/4) and from patients with various representative lung diseases, including cystic fibrosis (CF), alpha-1 anti-trypsin deficiency (��1-AT), sarcoidosis (SARC), systemic sclerosis (SSc), and interstitial pulmonary fibrosis (IPF). The sample numbers analyzed for each group are: Normal (n = 12), G0 (n = 12), G2 (n = 12), G3/4 (n = 20), IPF (n = 18), CF (n = 10), Sarc (n = 4), SSc (n = 6) and ��1AT (n = 7). Data represent mean��SD. Atg4, Atg5-atg12 and Atg7 data were normalized to ��-actin.*p#p
