Abstract:
The mammalian SWI/SNF complex is one of ATP-dependent chromatin-remodeling complexes, which plays important roles in cell proliferation, differentiation, development and tumor suppression. ARID1A (AT-rich interactive domain-containing protein 1A) is a large subunit of SWI/SNF complex, and also an ARID family member with non- sequence-specific DNA binding activity. ARID1A is a tumor suppressor gene which is frequently mutated in many cancers, such as ovarian, bladder and gastric cancers. ARID1A can suppress cell proliferation through the up-regulation of p21 and the down-regulation of E2F-responsive genes. These findings on ARID1A and its role of tumor suppression contribute to understanding the mechanism of cancer development and developing new therapy for cancer.It is introduced in the review that ARID1A basic characteristic, related to cancer development, and biological role for full understanding of ARID1A.

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.
