Figure 9. Correlation between HOXB9 expression and MMR gene mutation and DNA methylation expression. (A) The analysis of HOXB9 expression and five MMR gene expression levels, including MLH1, MSH2, MSH6, PMS2, and EPCAM in pan-cancer. (B) The correlation analysis of HOXB9 expression level with four methyltransferase genes (DNMT1, DNMT2, DNMT3A, DNMT3B) in pan-cancer. *P < 0.05, **P < 0.01, ***P < 0.001.
