Abstract:
AT-Rich Interaction Domain 1A (ARID1A) is an important SWItch/Sucrose Non-Fermentation (SWI/SNF) chromatin remodeling complex subunit, and its coding gene has a high mutation frequency in many cancers. Current studies have reported that ARID1A mutational status is correlated to cancer development, including cell proliferation, invasiveness, metastasis, and morphological alterations. ARID1A acts as a tumor suppressor, regulating gene transcription, participating in DNA damage response, and influencing tumor immune microenvironment and signaling pathways. The absence of ARID1A in cancer can lead to widespread dysregulation of gene expression in cancer initiation, promotion, and progression. For patients with ARID1A mutations, effective individualized treatment can improve the prognosis of patients. In this review, we aim to discuss the mechanism of ARID1A mutations in cancer development and explore the significance of discoveries for treatment.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
