Abstract

The use of chemotherapy drugs for the treatment of cancer is an effective therapeutic measure. However, chemoresistance affects the effectiveness of the treatment. AKT overexpression has been observed in chemoresistance. AKT expression in colon cells induced cisplatin resistance. The present study demonstrated the role of reactive oxygen species (ROS) in the induction of AKT regulation by cisplatin through the activation of JAK2/STAT3 at the transcriptional level in colon cancer cells. HCT‑116 cells treated with cisplatin exhibited increased JAK2 and STAT3 activities. Reducing the expression of JAK2 in colon cancer cells using small interfering RNA (siRNA) decreased AKT expression. The present study demonstrated that AKT activation is closely associated with chemoresistance in human tumors. The inhibition of ROS decreased the levels of AKT in colon cancer cell lines. The JAK2/STAT3 pathway was also shown to mediate AKT expression and represents a potential target for overcoming cisplatin resistance in human tumors.
