Project description:The goal of this project was to explore the effect of NH3 and/or H2S effect on the mouse sperm RNA expression and the transgenerational effects. RNA-seq of mouse sperm samples from different groups (NH3 and or H2S treatment) in different generations was done to search for transgenerational effects on RNA expression.

Project description:Plethodontid salamanders are the largest family of salamanders and are classic models for studying the effect of rapidly evolving courtship pheromones on mating behavior and reproductive success. Despite interests in plethodontid reproduction, very little is known about the molecular composition of salamander gametes, as the extraordinary sizes of their genomes have impaired the development of various omic-scale resources. To identify what proteins may be expressed in salamander sperm, we performed DIA-MS on sperm samples from two plethodontid species, Plethodon shermani and Desmognathus ocoee. As the first detailed study of salamander sperm, this study partially fills in a critical taxonomic gap in the study of fertilization proteins in vertebrates.
Project description:Sperms being foreign to the female are to be promptly eliminated by the female local immune defense. However, avoiding the local immune defense sperm can be stored for lenthy period in the oviductal sperm reservoir. It is currently unknown whether oviductal sperm reservoirs changes their gene expression to tolerate the spermatozoa after mating or sperm free seminal plasma infusion. Therefore this was tested using Swedish Landrace pigs in this study using cDNA microarray. We used 12 sows seperated into three groups- either oestrus sows were inseminated with 50 ml BTS (control, n=4) or mated with boars (treatment 1, n=4) or inseminated with sperm-free seminal plasma (treatment 2, n=4). The utero-tubal junction was retrieved within 24 h of treatment by operation.
