|title=A 69-year-old woman with Coffin-Siris syndrome.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/30055038
|abstract=Coffin-Siris syndrome (CSS) is a rare intellectual disability syndrome classically characterized by aplasia or hypoplasia of the distal phalanx or nail of the fifth and other digits, distinctive facial features, hirsutism/hypertrichosis, and sparce scalp hair. It is genetically heterogeneous but most often caused by a pathogenic variant in the [[ARID1B]] gene. Previous clinical reports of CSS patients are mainly based on young or middle-aged individuals. Here, we report a 69-year-old woman with CSS phenotype and a pathogenic [[ARID1B]] loss-of-function variant c.5259_5260dup. She has severe intellectual disability but otherwise she is in relatively good health both physically and mentally. There is no evident history of chronic illness or progressive disability. CSS appears to be compatible with long survival and most likely it is underdiagnosed in geriatric patients with intellectual disability.

|title=SWI/SNF regulates a transcriptional program that induces senescence to prevent liver cancer.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/27737960
|abstract=Oncogene-induced senescence (OIS) is a potent tumor suppressor mechanism. To identify senescence regulators relevant to cancer, we screened an shRNA library targeting genes deleted in hepatocellular carcinoma (HCC). Here, we describe how knockdown of the SWI/SNF component [[ARID1B]] prevents OIS and cooperates with RAS to induce liver tumors. [[ARID1B]] controls p16  and p21  transcription but also regulates DNA damage, oxidative stress, and p53 induction, suggesting that SWI/SNF uses additional mechanisms to regulate senescence. To systematically identify SWI/SNF targets regulating senescence, we carried out a focused shRNA screen. We discovered several new senescence regulators, including [[ENTPD7]], an enzyme that hydrolyses nucleotides. [[ENTPD7]] affects oxidative stress, DNA damage, and senescence. Importantly, expression of [[ENTPD7]] or inhibition of nucleotide synthesis in [[ARID1B]]-depleted cells results in re-establishment of senescence. Our results identify novel mechanisms by which epigenetic regulators can affect tumor progression and suggest that prosenescence therapies could be employed against SWI/SNF-mutated cancers.
