SOD2 and cancer: In conclusion, this present study demonstrates that 4-AAQB inhibits the aberrant expression of SOD2 through the re-expression of hsa-miR-324-5p, the negative modulation of pluripotency transcription factors, the augmentation of the BAX/BCL-xL ratios, and the reprogramming of malignant colorectal cancer cells from the aggressive mesenchymal phenotype to a relatively benign epithelial phenotype, subsequently enhancing the sensitivity of the cancer cells to conventional chemotherapy and facilitating better prognosis, as depicted in our Schematic abstract.
