Single cell ATAC-seq analysis of H3.3K4M WT and Hom brain samples (10X Genomics Multiome)
Methylation of lysine4 on Histone H3 (H3K4) is require for promoter and enhancer activation at gene loci and presents distinct methylation patterns over developmental gene clusters. Disrupting in the writer, eraser and reader of H3K4 methylation is associated with developmental syndromes. However, less studies focus on the role of H3K4 methylation in development of interneuron and hypothalamus. Here, we explore the role of H3K4 methylation in the medial ganglionic eminence (MGE) derive interneuron and hypothalamus by directly mutating the lysine 4 on H3.3 to the methionine in mice. Overall design: The Nkx2.1-Cre;H3.3K4M;Sun1-sfGFP mice were generated to harvest all Nkx2.1-lineage GFP+ nuclei via flow cytometry.  Single nuclei from embryonic and adult samples from each genotype were prepared using 10X Genomics Multiome pipeline. Samples: E13.5 MGE and hypothalamus as well as P60 cortex and hypothalamus of H3.3K4M WT and Hom. In addition, one replicate for male and female for each condition.
