Correlation analysis for the expression of MRE11 and CD44 in OSCC tumor specimens and survival analysis for differential CD44 expression levels in OSCC patients. (A,B) Representative images of immunohistochemistry (IHC) staining for MRE11 and CD44 expression in the tumor tissue sections from OSCC patients were presented in (A). The quantitative IHC scores were analyzed with Pearson correlation (r) between MRE11 and CD44 in (B) (n = 88). (C) The overall survival of OSCC patients was analyzed via TCGA RNA-Seq datasets (TCGA-HNSC) for the low CD44 expression group (CD44^low; n = 192) versus the high CD44 expression group (CD44^high; n = 307) with log-rank test.
