Moreover, the correlation analysis between RARA-AS1 and MMR proteins reveals that at least three mismatch repair genes are significantly associated with RARA-AS1 in Breast invasive carcinoma (BRCA), GBM, LAML, LGG, LIHC, Pancreatic adenocarcinoma (PAAD), Testicular germ cell tumors (TGCT), and UVM (Fig. 4B). Here, RARA is linked to invasive breast carcinoma.
