Transcriptomic Study of Spermatogenesis in the Testis of Hu Sheep and Tibetan Sheep.

ABSTRACT: Numerous genes involved in male reproduction regulate testis development and spermatogenesis. In this study, the testis tissue transcriptome was used to identify candidate genes and key pathways associated with fecundity in sheep. Histological analysis of testis tissue using hematoxylin-eosin (HE) routine staining was performed for two sheep breeds. Overall, 466 differentially expressed genes (DEGs) were identified between Hu sheep (HS) and Tibetan sheep (TS) through RNA sequencing technology (RNA-Seq), including 226 upregulated and 240 downregulated genes. Functional analysis showed that several terms and pathways, such as "protein digestion and absorption", "cAMP signaling pathway", "focal adhesion", and "p53 signaling pathway" were closely related to testis development and spermatogenes
