Studies in gastric cancer and insulinoma cells have shown that TCF19 regulates the expression of G1 (e.g., cyclins A and E) and G2/M (cyclin B) cyclins (Miao et al, 2013), and BIM (Krautkramer et al, 2013), but its role in melanoma is not known. The gene discussed is BCL2L11; the disease is pancreatic insulinoma.
