STAT3 and non-small cell lung carcinoma: Because the levels of p300, p-STAT3, and MMP19 were higher than other molecules, thus we further examined IL-17RA, p300, p-STAT3 and MMP19 protein using NSCLC tissues arrays from 52 NSCLC patients (here, Ack-STAT3 did not detect owing to no commercial specific anti-Ack-STAT3).
