Abstract

Colorectal cancer (CRC) ranks fifth in terms of incidence rate and mortality among malignant tumors in China. Oxaliplatin (OXA) is a first‑line drug for the clinical treatment of CRC, but its antitumor effect is limited because of the development of drug resistance. The present study aimed to investigate whether the traditional Chinese medicine Huaier can regulate the Wnt/β‑catenin signaling pathway by affecting the expression of METTL3, thereby promoting the sensitivity of HCT‑8/L cells to OXA. The expression of METTL3 was analyzed based on the UCSC Xena and Gene Expression Omnibus databases. Silent METTL3 and overexpression METTL3 models were constructed, and Cell Counting Kit‑8 and flow cytometry were used to detect the effects of Huaier on the viability and apoptosis of HCT‑8/L cells. Western blotting, reverse transcription‑quantitative PCR, nuclear cytoplasmic separation and immunofluorescence were used to detect the effects of Huaier on the expression of METTL3, Pgp, Wnt/β‑catenin signaling pathway‑related proteins, apoptosis‑related proteins and related mRNA. The results demonstrated that patients with high expression levels of METTL3 had a shorter overall survival period. The expression level of METTL3 significantly increased in drug‑resistant CRC cells. Silencing METTL3 promoted apoptosis of CRC cells and increased their sensitivity to OXA by inhibiting the Wnt/β‑catenin signaling pathway. Huaier downregulated the expression of METTL3, thereby promoting apoptosis of drug‑resistant CRC cells and increasing their sensitivity to OXA by inhibiting the Wnt/β‑catenin signaling pathway.
