A study has suggested that high expression of ST6GALNAC1 is found in colon carcinogenic tumor stem cells, and high expression of ST6GALNAC1 can promote the expression of tumor stem cell marker protein CD44-associated antigen Stn, which can not only promote the tumorsphere-forming ability of tumor cells, but also promotes the resistance of tumor cells to chemotherapeutic drugs [4]. This evidence concerns the gene EEF1A2 and neoplasm.
