In this way, some genes involved in the cell cycle (RASSF1, CCNA1, and C13ORF18) [23,171,173]—those that contribute to cancer progression by increasing proliferation, invasion, and/or metastasis (PAX1, SEPT9, CDH1, DAPK1, hTERT1, hTERT2 and HIC1) [23,171,174] and those that affect cellular differentiation (TWIST1)—are regulated [23]. The gene discussed is RASSF1; the disease is cancer.
