From: PIWIL2 promotes progression of non-small cell lung cancer by inducing CDK2 and Cyclin A expression
Expression of PIWIL2 in NSCLC and multivariate Cox’s regression analyses of primary NSCLC patients (n = 126). Real-time PCR (a), western blot (b) and IHC (c) analysis of adjacent and NSCLC tissues. d Overall survival rates and its correlation with PIWIL2 expression. The cumulative overall survival rate for patients in the PIWIL2-high group was significantly lower than that for patients in the PIWIL2-low group (χ2 = 7.54; P = 0.03). e Disease-free survival rates and its correlation with PIWIL2 expression. The cumulative disease-free survival rate for patients in the PIWIL2-high group was significantly lower than that for patients in the PIWIL2-low group (χ2 = 8.78; P = 0.02). Real-time PCR data are presented as the mean ± SD (n = 30); **P < 0.01; for IHC, scale bars = 100 μm. The longest follow-up time was 100 months
