C-Myc Transcriptionally Amplifies Sox2 Target Genes to Regulate Self-Renewal in Multipotent Otic Progenitor Cells [ChIP-Seq]


ABSTRACT: An immortalized multipotent otic progenitor (iMOP) cell was generated by transient expression of c-Myc in Sox2-expressing otic progenitor cells. The procedure activated endogenous c-Myc expression in the cells and amplified existing Sox2-dependent transcripts to promote self-renewal. Downregulation of c-Myc expression following growth factor withdrawal resulted in a molecular switch from self-renewal to otic differentiation. ChIP-Seq was accomplished by immunoprecipitating endogenous RNA PolII, c-Myc and Sox2

Sensorineural hearing loss is caused by the loss of sensory hair cells and neurons of the inner ear. Once lost, these cell types are not replaced. Two genes expressed in the developing inner ear are c-Myc and Sox2. We created immortalized multipotent otic progenitor (iMOP) cells, a fate-restricted cell type, by transient expression of C-MYC in SOX2-expressing otic progenitor cells. This activated the endogenous C-MYC and amplified existing SOX2-dependent transcripts to promote self-renewal. RNA-  ...[more]
