NUF2 and squamous cell lung carcinoma: The data analysis showed that NUF2 mRNA was highly expressed in 16 types of human cancer (Supplementary Table S1) (Figure 1A), among which 7 types of cancer with abnormal NUF2 mRNA expression profiles presented with a significantly differential prognosis, namely KIRC (kidney renal clear cell carcinoma), KIRP (kidney renal papillary cell carcinoma), LIHC (liver hepatocellular carcinoma), LUAD (lung adenocarcinoma), UCEC (uterine corpus endometrial carcinoma), LUSC (lung squamous cell carcinoma), and PAAD (pancreatic ductal adenocarcinoma) (Figure 1B).
