Recent data have provided information regarding the profiles of clear cell carcinoma of the ovary (CCC) with adenine-thymine rich interactive domain 1A (ARID1A) mutations. The purpose of this review was to summarize current knowledge regarding the molecular mechanisms involved in CCC tumorigenesis and to describe the central role played by the aberrant chromatin remodeling. The present article reviews the English-language literature for biochemical studies on the ARID1A mutation and chromatin remodeling in CCC. ARID1A is responsible for directing the SWI/SNF complex to target promoters and regulates the transcription of certain genes by altering the chromatin structure around those genes. The mutation spectrum of ARID1A was enriched for C to T transitions. CCC and clear cell renal cell carcinoma (ccRCC) resemble each other pathogenetically. Dysfunction of the ARID1A protein, which occurs with VHL mutations in ccRCC, is responsible for loss of the assembly of the ARID1A-mediated histone H2B complex. Therefore, ARID1A acts as a chromatin remodeling modifier, which stimulates cell signaling that can lead to cell cycle arrest and cell death in the event of DNA damage. The dysfunction of ARID1A may result in susceptibility to CCC carcinogenesis through a defect in the repair or replication of damaged DNA.
