The advancement of tumor cell metastasis is significantly influenced by epithelial‑to‑mesenchymal transi‑ tion (EMT), and metastasis is a prominent contributor to the mortality of patients diagnosed with colorectal cancer (CRC) . AT‑rich interactive domain‑containing protein 1A (ARID1A), which acts as a tumor suppressor, frequently exhibits a loss‑of‑function mutation in metastatic CRC tissues. However, the underlying molecular mechanisms of ARID1A relating to EMT remain poorly understood. The present study aimed to clarify the association between ARID1A and eMT regulation in human crc cells. The investigation into the loss of ARID1A expression in tissues from patients with CRC was performed using immunohistochemistry. Furthermore, ARID1A‑overexpressing SW48 cells were established using lentiviruses carrying human full‑length ARID1A. The results revealed that overexpression of ARID1A induced cellular morphological changes by promoting the tight junction molecule zonula occludens 1 (ZO‑1) and the adherens junction molecule E‑cadherin, whereas it decreased the intermediate filament protein vimentin . The results of reverse transcription‑quantitative PCR also confirmed that ARID1A overexpression upregulated the mRNA expres‑ sion levels of TJP1/ZO‑1 and CDH1/ E‑cadherin, and downregulated VIM/vimentin and zinc finger E‑box binding homeobox 1 expression, which are considered epithelial and mesenchymal markers, respectively. In addition, the overex‑ pression of ARID1A in CRC cells resulted in a suppression of cell motility and migratory capabilities.

Notably, ARID1A overex‑ pression could reverse the EMT‑like phenotype and inhibit cell migration through alterations in EMT‑related markers, leading to the inhibition of malignant progression. In conclu‑ sion, ARID1A may serve as a biomarker and therapeutic target in the clinical management of metastatic crc.  \nIntroduction  \ncolorectal cancer (crc) is a common cause of cancer morbidity and mortality; it is the third most frequently diag‑ nosed malignancy worldwide and the second most common cause of cancer‑related mortality (1‑3) . According to global cancer statistics, >1. 85 million new cases ofCRC (9. 8% of total cancer cases) and an estimated 850,000 CRC‑related deaths (9 . 2% of total cancer‑related deaths) occurred in 2020 (2,4) . Among patients with CRC, 20% have metastatic CRC and 40% present with recurrence after previous localized disease treatment. Notably, prognosis of metastatic CRC is poor, with a 5‑year survival rate of \u003C20%(5), and these patients often develop resistance to systemic therapy.
