Dupuis S, Girault MS, Le Beulze M, Ialy-Radio C, Bermúdez-Guzmán L, Ziyyat A, Barbaux S. The lack of Tex44 causes severe subfertility with flagellar abnormalities in male mice. Cell Mol Biol Lett 2024; 29:74. [PMID: 38750428 PMCID: PMC11094962 DOI: 10.1186/s11658-024-00587-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 04/29/2024] [Indexed: 05/19/2024] Open
Abstract
By analyzing a mouse Interspecific Recombinant Congenic Strain (IRCS), we previously identified a quantitative trait locus (QTL), called Mafq1 on mouse chromosome 1, that is associated with male hypofertility and ultrastructural sperm abnormalities. Within this locus, we identified a new candidate gene that could be implicated in a reproductive phenotype: Tex44 (Testis-expressed protein 44). We thus performed a CRISPR/Cas9-mediated complete deletion of this gene in mice in order to study its function. Tex44-KO males were severely hypofertile in vivo and in vitro due to a drastic reduction of sperm motility which itself resulted from important morphological sperm abnormalities. Namely, Tex44-KO sperm showed a disorganized junction between the midpiece and the principal piece of the flagellum, leading to a 180° flagellar bending in this region. In addition, the loss of some axonemal microtubule doublets and outer dense fibers in the flagellum's principal piece has been observed. Our results suggest that, in mice, TEX44 is implicated in the correct set-up of the sperm flagellum during spermiogenesis and its absence leads to flagellar abnormalities and consequently to severe male hypofertility.

J Anim Sci 2024; 102:skae196. [PMID: 39008364 PMCID: PMC11345516 DOI: 10.1093/jas/skae196] [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: 03/18/2024] [Accepted: 07/13/2024] [Indexed: 07/17/2024] Open
Abstract
This study used a porcine model to systematically investigate whether carboxyfullerene C60(CF-C60) can be used for sperm preservation. The results indicated that CF-C60 supplementation can preserve porcine sperm quality during storage at 17 °C. This effect was attributable to an improvement in the antioxidant capacity of sperm through a decrease in the reactive oxygen species (ROS) level. Additionally, CF-C60 can maintain mitochondrial function, inhibit sperm apoptosis through the ROS/Cytochrome C (Cyt C)/Caspase 3 signaling pathway, and mediate suppression of bacterial growth through the effects of ROS. Finally, the results of artificial insemination experiments indicated that insemination with CF-C60-treated sperm can increase the total number of offspring born and reduce the number of deformed piglets. Thus, CF-C60 is safe for use as a component of semen diluent for sperm storage.
