FOXC1 and cancer: The hypermethylation phenotype associated with the molecular factors forkhead box protein C1 (FOXC1), cluster of differentiation 99 (CD99) and DNA methyltransferase 3A (DNMT3A), as well as the presence of mutations in genes regulating the differentiation of the hematopoietic system (RUNX1, CEBPA, GATA2) in cancer cells, increases their stem cell-like phenotype (stemness).
