We found lots of them might play a key role in the transformation of enterocyte progenitor cells to cancer cells such as MALAT1 [59], B2M [60], EEF1A1 [61], RPL5 [62], B3GNT7 [63], RHOB [64] and ACTB [65] might play a key role in the transformation of enterocyte progenitor cells to cancer cells. The gene discussed is B2M; the disease is cancer.
