Arid1a Haploinsufficiency Initiates Neural Crest Transformation In A Mouse Model Of Mycn-Driven Neuroblastoma, Kirby A. Wallace
Theses and Dissertations (ETD)
Mouse models of cancer are critical for developing therapeutic treatments for pediatric patients. Recent sequencing studies of neuroblastoma (NBL) patient tumors have uncovered precise deletions in the chromatin remodeler and tumor suppressor gene (TSG) ARID1A. Additional causal studies supported ARID1A’s candidacy as a putative 1p36 TSG in MYCN-driven NBL. This study aimed to causally test Arid1a loss during Mycn-driven NBL initiation through the development of a mouse model of high risk NBL.In this study, we modified a Mycn-driven mouse model of NBL to incorporate Cre mediated deletion of floxed Arid1a. Briefly, in freshly isolated embryonic day 9.5 primary trunk neural …
