WIN 18,446 2dpp testis culture

Project description:Analysis of 2dpp whole testes cultured for 24h in the presence of WIN 18,446, a BDAD compound. BDADs (Bis-(dichloroacetyl)-diamines) have been shown previously to inhibit spermatogenesis and function as male contraceptives in many species; however, their mechanism of action has yet to be fully described. Results provide insight into the ability of WIN 18,446 to inhibit retinoic acid synthesis in the murine testis. Testes were removed from 2dpp 129 mice and cultured for 24h in an organ culture mold in the presence of WIN 18,446. Total RNA was extracted and hybridized to Affymetrix Mouse Genome 430 2.0 arrays.

Thyroid hormone regulated genes in the neonatal testis

Project description:An excess in thyroid hormone during rodent neonatal life causes abnormal prolifration and maturation of testicular cells, leading to reduced testis size and impairments in steroidogenesis, Sertoli cell function, spermatogenesis and fertility. The high expression of type 3 deiodinase in the neonatal testis protects this tissue from premature exposure to thyroid hormones, since this gene (Dio3) function is to degrade thyroid hormones. DIO3-deficient mice (Dio3KO) exhibit a marked reduction in Sertoli cell proliferation and testis size, abnormalities in the reproductive axis and impaired fertility (Martinez et al. 2016, Endocrinology157:1276). To identify genes that are untimely regulated by thyroid hormone in the developing testes, we have performed RNAseq in testis total RNA from wild type and DIO3KO mouse neonates.

Profiling of long noncoding RNAs and mRNAs in neonatal and adult mouse testis

Project description:Todate, the investigation into the molecular mechanisms of testis development and spermatogenesis has largely focused on the role of protein-coding genes and small noncoding RNA including microRNAs and piRNAs. In recent years, long noncoding RNAs (lncRNAs) have been shown to play critical regulatory roles in mammalian development. To understand the role of lncRNAs in development of the mammalian testis and spermatogenesis, we firstly utilized commercial microarray to systematically investigate lncRNAs expression profiles of neonatal (6-day-old) and adult (8-week-old) mouse testis. By comparison the lncRNAs expression profiles of two developmental stage of testes, we obtained the differentially expressed lncRNAs and examined their genomic context, promoter characteristics, neighbored protein-coding genes, provide an important foundation for future research on molecular mechanisms of lncRNAs in mammalian testis development and spermatogenesis.

A comprehensive roadmap of spermatogenesis and testis niche from single-cell RNA-seq

Project description:Continuous sperm production is not necessary for the survival of the organism, but is essential to maintain a species. The process of spermatogenesis is comprised of three phases: mitotic proliferation, meiosis, and spermiogenesis. To illuminate germline intrinsic and extrinsic programs, we performed single-cell RNA sequencing on ~35K cells from the adult mouse testis. This analysis provides a comprehensive molecular atlas of the testis, identifying both known and novel cell types. We demonstrate for the first time the continuous nature of germ cell differentiation, provide molecular signatures and subtype-specific molecular markers, and identify several novel candidate regulators of spermatogenesis. Finally, we demonstrate in vivo using spatial mapping that germ and somatic cell molecular subtypes correspond to previously defined histological cell types residing at different stages of seminiferous epithelial cycle. Taken together, our results unveil the complexity of the testis, and provide a global, unbiased roadmap of the in vivo gametogenesis program.
