GATA2 is overexpressed in Gata1s erythroid
cells. RNA-seq (A) and RT-qPCR (B) confirming the increased
expression of GATA2 in G1s erythroid cells. Total mRNA was extracted
from E13.5 fetal liver cells for RT-qPCR. (C) Tracks depicting
CUT&RUN-seq of GATA1, GATA1s, and H3K27me3 as well as ATAC-seq at
the genomic locus of Gata2 in the R1/2 and R3
populations. Histograms were normalized to account for differences in
the number of reads per library. Four well-studied regulatory elements
(−3.9 kb, −2.8 kb, −1.8 kb, and +9.5 kb) and
the proximal promoter of Gata2 are indicated by arrows.
Red dashed boxes (right) highlight the changes in H3K27me3 and
differential chromatin accessibility (ATAC-seq) at GATA1/GATA1s-binding
sites and the Gata2 proximal promoter.
