Immunohistochemical analysis of expression of ZCCHC14 in normal lung tissues and NSCLC tissues. A, Immunohistochemical experiments showed that ZCCHC14 was observed in normal lung bronchial epithelial tissues and weakened or absent in lung squamous cell carcinoma. Original magnification, ×200. B, expression of ZCCHC14 was normal in normal alveolar tissues and low or absent in adenocarcinoma. C, the survival time of patients with ZCCHC14 protein expression in NSCLC was analysed by the overall Kaplan‐Meier survival curve. D, Kaplan–Meier curves of ZCCHC14 mRNA expression in NSCLC as retrieved from the KM Plotter database
