Catalytic dependent and independent roles of Tet3 in activation of ectodermal and silencing of mesodermal programs during neuroectoderm specification


ABSTRACT: In this study: (1) we distinguished Tet3 target genes that are regulated by its catalytic vs. noncatalytic functions in neuroectoderm (NE) cells by transcriptomic profiling of Tet3 wildtype (WT), Tet3 catalytic mutant (Mut), and Tet3 knockout (KO) NE cells by RNA-seq. (2) We mapped genome-wide DNA methylation of Tet3-WT, Tet3-Mut, and Tet3-KO NE cells by WGBS. (3) We determined Tet3 genome-wide occupancy in Tet3-WT NE cells by CUT&Tag. (4) We mapped 5hmC rich regions in Tet3-WT, Tet3-Mut, and Tet3-KO NE cells by hmeDIP. (5) We overexpressed (OE) the Tet3 target gene Dnmt1 (D) or an empty vector (EV) in Tet3-WT, Tet3-Mut, and Tet3-KO NE cells and assessed gene expression by RNA-seq. (6) We overexpressed (OE) Tet3 (T) or an empty vector (EV) in Tet3-WT, Tet3-Mut, and Tet3-KO NE cells and examined gene expression changes in these cells by RNA-seq.
