Functional analysis of Vsx2 super-enhancer reveals an autoregulatory network governing Vsx2 expression during retinogenesis [RNA-seq_mouse]

Project description:The roles of retinal cis-regulatory landscape in controlling the expression of gene regulatory networks important for retinogenesis remain poorly understood. Vsx2 is a transcription factor essential for retinal proliferation and bipolar cell differentiation but the molecular mechanisms underlying its developmental roles are unclear. Here, we profiled VSX2 genomic occupancy during mouse retinogenesis, revealing extensive retinal gene regulatory networks associated with Vsx2 during development. We defined an autoregulatory loop in which VSX2 binds and transactivates its own enhancer in association with the transcription factor PAX6 . The Vsx2 regulatory landscape contains elements that are required for Vsx2 expression, retinal proliferation and proper cell type differentiation. We further show that retinae in which the Vsx2 enhancer landscape has been largely deleted suffer a bias toward photoreceptor production. Genomic data indicate that VSX2 occupies cis-regulatory elements nearby genes associated with photoreceptor differentiation and homeostasis in mouse and human retinae, including a conserved region nearby the rod-specifying factor Prdm1. We provide evidence that VSX2 associates with OTX2 and can act to suppress OTX2-dependent enhancer transactivation of Prdm1 enhancer. Taken together, our analyses illuminate important mechanistic insights on how VSX2 is engaged with gene regulatory networks that are essential for retinal proliferation and cell fate acquisition.

Mettl3 regulates late retinogenesis

Project description:Mettl3 was conditionally knocked out from retinal progenitor cells. Metll3 deficient retinas exhibited disrupted cell cycle during late retinogenesis and abnormality in retinal architecture and physiology.

Mettl3 regulates late-stage retinogenesis

Project description:To study the function of Mettl3 during retinal development, we used Six3-Cre and Mettl3floxed mice to conditionally knock out Mettl3 from retinal progenitor cells. The mutant mice show defects in late-stage retinogenesis and structural and physiological homeostasis of the retina.

A framework to identify functional interactors that contribute to disrupted early retinal development in Vsx2 mutant mice

Project description:This SuperSeries is composed of the SubSeries listed below. The Vsx2 homeobox gene is expressed in the newly formed retinal domain during early eye development and mutations in the Vsx2 gene cause congenital microphthalmia. The primary disruptions in the early retina are compromised retinal identity (lineage infidelity), reduced proliferation, and delayed neurogenesis. One goal of the study was to use gene expression profiling to predict genetic interactions between Vsx2 and candidate functional interactors that contribute to the early retinal phenotype of the Vsx2-null mouse strain ocular retardation J (orJ). The orJ allele is a spontaneous, recessive allele caused by the presence of a premature stop codon in the Vsx2 homeodomain. The datasets contained within are from three independent experimental designs. One was to compare the retinal gene expression profiles from E12.5 embryos that are one of three genotypes: the orJ-homozygous mutant, the combinatorial orJ; Mitfmi heterozygous mutant, and the orJ-heterozygous mouse (control). Another analysis was to compare the gene expression profiles of E12.5 orJ-homozygous mutant retinal tissues cultured for 24 hour in the presence or absence of the RXR antagonist HX531. The other analysis was to compare the gene expression profiles of E12.5 orJ-homozygous mutant retinal tissues cultured for 24 hour in the presence or absence of the gamma-Secretase antagonist Dibenzazipine (DBZ).
