Overexpression of cell cycle‐related and expression‐elevated protein in tumor (CREPT) promotes non‐small‐cell lung tumor growth in vivo. A, Representative images of CREPT‐overexpressing and control Calu‐1 xenografts. B, Tumor volumes of CREPT‐overexpressing and control Calu‐1 xenografts. C, CREPT‐overexpressing Calu‐1 xenografts showed significantly increased tumor weight. D, Representative immunohistochemical staining of CREPT and Ki‐67 in xenograft tissues. E, The mRNA and protein expression level of Ki‐67 in xenograft tissues
