3'-UTR-seq of Mus musculus female and male hypothalamus across the pubertal transition

The hypothalamus is a functionally and cellularly complex tissue controlling many developmental processes, including puberty. While key hormonal aspects of puberty regulation in the hypothalamus are well established, understanding the genes, cell-types, and epigenetic mechanisms underlying and regulating puberty is limited. Here, we performed 3'-UTR-seq on the hypothalamus from both sexes of C57BL/6J mice at 5 ages spanning pubertal transition (postnatal days 12, 22, 27, 32, 37) (4-5 replicates per sex at each age) to examine genome-wide age- and sex-biased trends in gene expression in a cell-type aware manner. Sample collection, RNA extraction, and sequencing was completed using the same protocols and on the same mice as PMID: 3622112 (E-MTAB-9459). QuantSeq 3'mRNA-seq libraries were constructed from total RNA using an automated method with Agilent NGS Workstation. The resulting single-end libraries were sequenced at SickKids TCAG core on the Illumina v4 flow cell with SR50 bp cycles extended to 68 bp. A customized pipeline was developed and used for the analysis of reads obtained (PMID: 36221127 for details). Processed reads were mapped to mouse genome (mm10).
