Mitotic Arrest Deficient 2 Like 1 Contributes to Colorectal Cancer Cell Migration, Invasion, and Oxaliplatin Resistance Through the Wnt/β-Catenin Pathway
Colorectal cancer (CRC) is a highly prevalent malignancy, requiring chemotherapy for advanced stages of the disease. Previously, we found that mitotic arrest deficient 2 like 1 (MAD2L1) was upregulated and facilitated malignant proliferation in CRC. However, the association between MAD2L1 expression and tumor progression, as well as chemotherapy resistance in CRC, remains unclear. The progression capacities of CRC cells were assessed using transwell and wound healing assays, and the resistance to cisplatin in oxaliplatin-resistant CRC cells was assessed using CCK-8 assay and flow cytometry. Relevant protein levels of epithelial-to-mesenchymal transition (EMT) and Wnt/β-catenin pathway were analyzed using western blotting. Revealing the impact of MAD2L1 on metastasis and drug resistance in CRC through inhibition of the Wnt/β-catenin pathway. Knockdown of MAD2L1 attenuated the malignant progression of CRC cells, inhibited EMT, and blocked the Wnt/β-catenin pathway. MAD2L1 was significantly upregulated in oxaliplatin-resistant CRC cells, accompanied by the activation of the Wnt/β-catenin pathway. Knockdown of MAD2L1 effectively reversed oxaliplatin resistance, leading to apoptosis and downregulation of the protein expression levels of β-catenin, P-glycoprotein (P-gp), and ABCG2. After the knockdown of MAD2L1, the inhibition of the Wnt/β-catenin pathway exhibited a synergistic effect, effectively suppressing malignant progression and reversing oxaliplatin resistance in CRC cells. So, knockdown of MAD2L1 suppressed cell malignant progression, equally sensitized resistant CRC cells to oxaliplatin, potentially by blocking the activation of the Wnt/β-catenin pathway.
