(
A) Mouse cortex and hippocampus gene expression levels for Ezh2 and
Hsf1 depicted in the Allen Brain Atlas Transcriptomics explorer showing limited expression of Ezh2 across multiple neural tissues compared to
Hsf1. Levels are per cell type based on RNA-seq data. (
B) In situ hybridization brain image data with cellular-level resolution for Ezh2 (upper panel) and
Hsf1 (lower panel) depicting low expression levels for Ezh2. Left panel, ISH images, middle panel, gene expression images, right panel, expression in 3D reconstructed whole mouse brain. (
C) Metagene analysis of increase in Hsf1 binding (ChIP-seq data) across the start of B2 RNA regulated genes (
Supplementary file 1) between pre-stress and 12 min post-stress (KS <0.05). ChIP-deq data are from
Mahat et al., 2016. TSS represents the Transcription Start Site of these genes. This figure provides the rational why we started investigating Hsf1 as a candidate with a potential relation to B2 Biology and a potential effect on B2 RNA processing.
