Comprehensive analysis of Poly(A) tails in Mouse Testes and Ovaries using Nanopore direct RNA Sequencing. 

Germ cell development, gametogenesis, is a complex process in which dysfunction leads to infertility, a growing health and sociological problem worldwide. In both spermatogenesis and oogenesis, post-transcriptional gene expression regulation is crucial. Essentially, all mRNAs possess non-templated poly(A) tails, which composition and dynamics (elongation, shortening, and modifications) determine the fate of mRNA. In this context, we present a comprehensive transcriptomic dataset that focuses on mRNA poly(A) tails metabolism in murine testes. Analyzed RNA samples are isolated from wild-type and transgenic mice lacking TENT5C polymerase, which can extend poly(A) tails in the cytoplasm. Both whole testes material, as well as male gametes at different developmental stages (round or long spermatids) were analyzed.
