Expression of serum starvation-induced genes (SIGs) in TCGA-HNSCC patients. The expression of 21 genes that showed significant changes in expression by serum starvation and their relative expression levels in TCGA-HNSCC patients were determined in primary tumors and solid normal tissues. (A) Box plots of the expression of 11 genes (AGR2, BST2, CALR, CD22, DDIT3, FOXA2, HSPA5, PIWIL4, PYCR1, SGK3, and TRIB3) that have been up-regulated more than two-fold. (B) Box plots of the expression of 10 genes (ATOH8, AXIN2, BNIP3, CCL2, CDKN2C, CNTN1, EGLN3, ID2, SERPINB3, and S100A8) that were down-regulated by more than 50%. * P < 0.05. (C) Heat map of 21 SIG expression profiles. Colors from blue to red indicate low to high expression levels.
