TY - JOUR AB - Heterogeneous ribonucleoprotein AB (hnRNPAB) is one of the main members of the nuclear heterogeneous ribonucleoprotein family and plays a crucial role in the occurrence and development of tumours. A previous study by the authors demonstrated that hnRNPAB was highly expressed in colorectal cancer tissues and was closely associated with a poor prognosis of patients. However, the contribution of hnRNPAB to the tumorigenesis and drug resistance of colorectal cancer (CRC) stem cells (CSCs) remains elusive. The aim of the present study was thus to examine whether hnRNPAB can enhance the characteristics of colorectal CSCs and chemotherapeutic drug resistance by altering the cell cycle and the apoptosis of colorectal CSCs. The results revealed that the expression of hnRNPAB in colorectal CSCs was increased compared with that in their parental cells. The knockdown of hnRNPAB reduced the sphere formation of and the levels of CSC markers in colorectal CSCs, enhanced sensitivity to 5‑fluorouracil and oxaliplatin chemotherapy and increased apoptosis. Taken together, these data indicate the role of hnRNPAB in maintaining CSC properties and provide a novel therapeutic target for the treatment of CRC and particularly, drug resistance.
