PINK1 and lung cancer: We also conducted the detailed evaluation of PINK1 expression and clinicopathological characteristics in lung cancer. Figures 4C, D showed that PINK1 played a protective role in lung cancer patients with the following clinicopathological characteristics: female sex (OS: P = 1.3e-07; PPS: P = 0.018), adenocarcinoma (OS: P = 9e-09; PPS: P = 0.0065) and pathology stage 1(OS: P = 5.9e-10; PPS: P = 0.0017).
