Bulk_sequencing_study_for_human_male_germline

This study aims to understand the gene expression changes in male reproductive tissues during spermatogenesis using integrated multi-omics analysis. Different populations from testis biopsies, including spermatogonia stem cells, primary spermatocytes, secondary spermatocytes, spermatids and mature sperms, were sorted based on the DNA content. In addition to the G&T sequencing results for single cells, we sorted bulk samples for those populations for Nanoseq to detect the mutations at low error rate.

EGAD00001015828	Lifestyle, environmental and other exposures to exogenous mutagens generate somatic mutations in normal human cells in vivo and increase cancer risk. However, the global repertoire of exogenous mutagen exposures is uncertain. Using single-molecule duplex sequencing of normal kidney (n=319) and blood (n=272) samples from 10 countries, we show that kidney proximal tubule cells exhibit higher mutation rates than most normal cell types despite low cell division rates. Compared to cells from kidney glomeruli, medulla, distal tubules, or peripheral blood, proximal tubule cells show marked enrichment of mutational signatures due to the exogenous carcinogenic mutagens, aristolochic acids, and of several signatures of unknown causes. The results suggest the existence of multiple, common, systemically circulated mutagens affecting human populations and indicate that the genomes of kidney proximal tubule cells report such exposures with high sensitivity.
