The study found that ARID3A expression increased in CRC tissues, potentially acting as a tumor-promoting factor. Overexpression of ARID3A can enhance tumor cell proliferation, migration, and invasion, targeting AURKA to facilitate the malignant phenotype of CRC cells. The ratio of ARID3A and AURKA could serve as a potential biomarker for predicting prognosis in CRC.
Colorectal cancer (CRC) is one of the most common malignant tumours, and its morbidity and mortality rates are relatively high. However, the aetiology and pathogenesis of CRC have not been clearly elucidated to date. AT-rich interaction domain 3A (ARID3A) is a member of the ARID3 family and a transcription factor that can bind to specific DNA sites to regulate gene expression. It was reported that ARID3A is involved in various biological processes and may be related to carcinogenesis. In this study, by assessing the mRNA level of ARID3A in TCGA database, we found that ARID3A expression increased in CRC tissues, and proposed that ARID3A could act as a tumour-promoting factor in the development of CRC. To verify this hypothesis, we used cell proliferation, migration and invasion assays to assess the effect of ARID3A on CRC cells. We revealed that ARID3A overexpression enhanced tumour cell proliferation, migration and invasion. ARID3A could target Aurora kinase A (AURKA) to facilitate the malignant phenotype of CRC cells, and patients with a higher ratio of AURKA and ARID3A had a better overall survival. Conclusively, this study showed that ARID3A targeted AURKA to facilitate the development of CRC. The ratio of ARID3A and AURKA could be used as a potential biomarker to predict prognosis, providing a new strategy for the diagnosis and prognosis of CRC.
