(Submitter supplied) The goal of this study was to identify important genetic pathways that are altered in mammary tumor cells upon over-expression of the tumor suppressor gene Arid1a. The results of this experiment revealed that Arid1a helps regulate key cell-cycle checkpoint and growth regulatory pathways, either directly or indirectly. This helped explain in part the significant decrease in cell proliferation and tumor growth phenotypes observed both in vitro and in vivo, when comparing the same samples analyzed here by RNA-seq (untransduced replicates vs. more...

(Submitter supplied) Illumina array was employed to analyze the genes whose expression are altered when ARID1A gene is downregulated by shRNA in normal ovarian surface epithelial cells OSE4 and IOSE80pc. This leads to discovery of p53-regulated genes such as p21 and SMAD3.

Analysis of OSE4 and IOSE80pc ovarian surface epithelial cells depleted for ARID1A, which encodes large nuclear protein p270. ARID1A depletion enhances OSE4 and IOSE80pc proliferation. OSE4 cells become highly tumorigenic upon ARID1A depletion. Results suggest a tumor-suppressor role for ARID1A.

(Submitter supplied) Genes encoding subunits of SWI/SNF chromatin remodeling complexes are collectively mutated in ~20% of all human cancers. Although ARID1A is the most frequent target of mutations, the mechanism by which its inactivation promotes tumorigenesis is unclear. Here, we demonstrate that Arid1a functions as a tumor suppressor in the mouse colon, but not the small intestine, and that invasive ARID1A-deficient adenocarcinomas resemble human colorectal cancer (CRC). more...

(Submitter supplied) WAP-Cre:Ptenf/f:p53lox.stop.lox_R270H composite mice were generated by genetic crossing. In these mice, Pten is deleted and a R270H p53 mutation in the DNA binding domain is induced upon expression of Cre recombinase in pregnancy-identified alveolar progenitors. Tumors were characterized by histology, marker analysis, various bioinformatics methods, high-throughput (HTP) FDA-drug screen as well as orthotopic injection to quantify tumor initiating cells (TICs) and tail-vein injection to identify lung-metastasis. more...

(Submitter supplied) ARID1A is a component of the mammalian SWI/SNF complex involved in chromatin remodeling. A functional SWI/SNF complex is required for diverse physiological processes including hematopoiesis, however, the precise role played by ARID1A in hematopoietic development is unclear. Here we utilize hematopoietic cell-specific deletion of Arid1a in mice to uncover its role during adult hematopoiesis. We demonstrate that ARID1A is essential for maintaining the frequency and function of hematopoietic stem cells and its loss impaired the differentiation of both myeloid and lymphoid lineages. more...

(Submitter supplied) ARID1A is hypothesized to be one of the most common tumor suppressors in human cancer. However, the functional consequences of ARID1A gain and loss are not clear. We report that mice with complete liver-specific Arid1a deficiency were resistant to MYC induced liver carcinogenesis, indicating a requirement during tumor initiation. Mechanistically, Arid1a loss constrained tumor formation by reducing Cytochrome P450 expression, which in turn mitigated oxidative stress. more...

(Submitter supplied) ARID1A, encoding a subunit of the SWI/SNF chromatin remodeling complex, is the most mutated epigenetic regulator in human cancers. ARID1A and TP53 mutations are typically mutually exclusive. Therapeutic approaches that correlate with ARID1A mutational status remain a challenge. Here, we show that HDAC6 activity is essential in ARID1A-mutated ovarian cancers. Inhibition of HDAC6 activity using a clinically applicable small molecule inhibitor significantly improved the survival of mice bearing ARID1A-mutated ovarian tumors. more...
