SLC28A1 and neoplasm: Other studies have also demonstrated CNT1 to be a putative tumor suppressor with chemosensitizer properties, as it influences tumor cell proliferation and drives the accumulation of several chemotherapeutic cargos inside cancer cells, including fluoropyrimidines (e.g., gemcitabine) and hypomethylating nucleoside drugs (azacytidine, decitabine, zebularine)23–25.
