[PMID: 38254386 PMCID: PMC10812427 DOI: 10.3390/ani14020217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 12/18/2023] [Accepted: 12/28/2023] [Indexed: 01/24/2024] Open
Abstract
Studying proteins associated with sex chromosomes can provide insights into sex-specific proteins. Membrane proteins accessible through the cell surface may serve as excellent targets for diagnostic, therapeutic, or even technological purposes, such as sperm sexing technologies. In this context, proteins encoded by sex chromosomes have the potential to become targets for X- or Y-chromosome-bearing spermatozoa. Due to the limited availability of proteomic studies on rabbit spermatozoa and poorly annotated databases for rabbits compared to humans, a bioinformatic analysis of the available rabbit X chromosome proteome (RX), as well as the human X (HX) and Y (HY) chromosomes proteome, was conducted to identify potential targets that could be accessible from the cell surface and predict which of the potential targets identified in humans might also exist in rabbits. We identified 100, 211, and 3 proteins associated with the plasma membrane or cell surface for RX, HX, and HY, respectively, of which 61, 132, and 3 proteins exhibit potential as targets as they were predicted to be accessible from the cell surface. Cross-referencing the potential HX targets with the rabbit proteome revealed an additional 60 proteins with the potential to be RX targets, resulting in a total of 121 potential RX targets. In addition, at least 53 possible common HX and RX targets have been previously identified in human spermatozoa, emphasizing their potential as targets of X-chromosome-bearing spermatozoa. Further proteomic studies on rabbit sperm will be essential to identify and validate the usefulness of these proteins for application in rabbit sperm sorting techniques as targets of X-chromosome-bearing spermatozoa.

[PMID: 38167777 PMCID: PMC10998464 DOI: 10.1093/jas/skad422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 01/02/2024] [Indexed: 01/05/2024] Open
Abstract
The demand for goat milk products has increased exponentially with the growth of the global population. The shortage of dairy products will be addressed extraordinarily by manipulating the female rate of goat offspring to expand the goat population and goat milk yield. No studies have reported bioinformatic analyses of X- and Y-bearing sperm of dairy goats, although this will contribute to exploring novel and applied sex-skewing technologies. Regulatory subunit of the histone methyltransferase complex (DPY30) was determined to be the key differentially expressed protein (DEP) among 15 DEPs identified in the present study. The spatiotemporal expression of DPY30 strongly suggested a functional involvement of the protein in spermatogenesis. DPY30 promoted meiosis via upregulating SYCP3, which played a crucial role in mediating sex ratio skewing in goats. Although DPY30 suppressed the self-renewal of spermatogonia stem cells through AKT/PLZF, DPY30 inhibition in the testis did not induce testicular dysgenesis. Based on the biosafety assessment in mice testes, lentivirus-mediated DPY30 knockdown in bucks' testes increased X-bearing sperm proportion and female kids' rate (22.8 percentage points) without affecting sperm quality, pregnancy rate, and kidding rate. This study provides the first evidence of the DEGs in the sexed sperm of dairy goats. DPY30 inhibition in the testes of bucks increased the female kids' rate without influencing reproductive performance. The present study provides evidence for expanding the female dairy goat population to address the concern of dairy product shortage.

Abstract
This review presents information on biochemical features of spermatozoa bearing X or Y chromosome, enabling production of a sperm fraction with pre-defined sex chromosome. The almost only technology currently used for such separation (called sexing) is based on the fluorescence-activated cell sorting of sperm depending on DNA content. In addition to the applied aspects, this technology made it possible to analyze properties of the isolated populations of spermatozoa bearing X or Y chromosome. In recent years, existence of the differences between these populations at the transcriptome and proteome level have been reported in a number of studies. It is noteworthy that these differences are primarily related to the energy metabolism and flagellar structural proteins. New methods of sperm enrichment with X or Y chromosome cells are based on the differences in motility between the spermatozoa with different sex chromosomes. Sperm sexing is a part of the widespread protocol of artificial insemination of cows with cryopreserved semen, it allows to increase proportion of the offspring with the required sex. In addition, advances in the separation of X and Y spermatozoa may allow this approach to be applied in clinical practice to avoid sex-linked diseases.
