(A) qRT-PCR analysis of miR-576–3p in two bronchial epithelial cell lines and a panel of lung adenocarcinoma cell lines; (triplicates) SEM. (B) qRT-PCR analysis of normal human lung and lung adenocarcinoma patient samples; (triplicates) SEM; *P=5.8×10−3, two-tailed t-test. (C, D) qRT-PCR data from B grouped as early-stage (I & II) and late-stage (III & IV) (C) or separated into tumor stage (D); (triplicates) SEM; late-stage, C, *P=3×10−3; Stage III, D, *P=8.3×10−3; Stage IV, D, *P=0.038, one-tailed t-test. All data are relative to the endogenous control RNU6B small RNA.
