Project description:Histone modifications and CTCF mark the locations of genomic regulatory regions -- including promoters, enhancers, and insulators -- and have not been previously annotated for the domestic cat genome. Understanding where non-coding sequence variants fall in relation to regulatory regions is vital for determining their impact on gene function and their ability to cause disease. The addition of replicated feline ChIP-seq data from multiple tissues will aid in interpretation of non-coding variants, furthering characterization of genetic diseases and genetic test development.
Project description:The domestic cat germinal vesicle (GV), which is physiologically similar to the human GV, gains the intrinsic ability to resume meiosis and support early embryo development during the pre-antral-to-antral follicle transition. However, little is known about nuclear proteins that contribute to this developmental process. We performed proteomic analysis of GVs identified candidate proteins for oocyte competence acquisition.
Project description:Extracellular vesicles (EVs) secreted by the epididymal epithelium transfer to spermatozoa key proteins that are essential in promoting motility and subsequent fertilization success. Using the domestic cat model, the objectives were to (1) characterize and compare protein content of EVs between segments of the epididymis, and (2) compare EV protein compositions between normo- and teratospermic individuals (producing >60% of abnormal spermatozoa).
Project description:Using RNA-seq to sequence the transcriptomes of β-cat lox(ex3) (Ctrl) and β-cat lox(ex3);Nex-Cre (β-cat Ovp) mice, we did not find significant change in the expression level of classical Wnt target genes.
