HSD17B4 and lung carcinoma: Although no significant correlation between HSD17B4 and MIKI67 expression (Supplementary Figure S3I, p > 0.05) was shown in CPTAC lung cancer, the other two proteins (ACAA1 and PXMP4) were confirmed to be negatively correlated with MKI67 expression (Supplementary Figures S3J,K, p < 0.01), indicating their potential roles in regulation of NSCLC growth.
