CEP20 and neoplasm: To further identify the specific mechanism of CEP20 in NSCLC cells, we divided NSCLC tumor samples (LUAD and LUSC samples, n = 1014) in the TCGA database into three groups based on CEP20 expression: relatively high (CEP20-high, n = 253); relatively low (CEP20-low, n = 253), and medium (CEP20-median, n = 508).
