Bmi1 Deficient Mice Exhibit Male Infertility
Previous studies have demonstrated that the polycomb repressor Bmi1 is universally expressed in all types of testicular cells and might regulate the spermatogonia proliferation, however, it is unclear whether Bmi1 plays a critical role in maintaining normal male fertility in vivo. To answer this question, we first confirmed that Bmi1 is universally expressed in all types of testicular cells and...
متن کاملMale infertility, impaired sperm motility, and hydrocephalus in mice deficient in sperm-associated antigen 6.
Gene targeting was used to create mice lacking sperm-associated antigen 6 (Spag6), the murine orthologue of Chlamydomonas PF16, an axonemal protein containing eight armadillo repeats predicted to be important for flagellar motility and stability of the axoneme central apparatus. Within 8 weeks of birth, approximately 50% of Spag6-deficient animals died with hydrocephalus. Spag6-deficient males ...
متن کاملMale infertility, impaired spermatogenesis, and azoospermia in mice deficient for the pseudophosphatase Sbf1.
Pseudophosphatases display extensive sequence similarities to phosphatases but harbor amino acid alterations in their active-site consensus motifs that render them catalytically inactive. A potential role in substrate trapping or docking has been proposed, but the specific requirements for pseudophosphatases during development and differentiation are unknown. We demonstrate here that Sbf1, a ps...
متن کاملACUPUNCTURE AND MALE INFERTILITY About male infertility
The clinical definition of male infertility is the presence of abnormal semen parameters in the male partner of a couple who have been unable to conceive after 1 year of unprotected intercourse (Dohle 2010). The World Health Organization defines male factor infertility as the presence of one or more abnormalities in the semen analysis, or the presence of inadequate sexual or ejaculatory functio...
متن کاملMice deficient in the axonemal protein Tektin-t exhibit male infertility and immotile-cilium syndrome due to impaired inner arm dynein function.
The haploid germ cell-specific Tektin-t protein is a member of the Tektin family of proteins that form filaments in flagellar, ciliary, and axonemal microtubules. To investigate the physiological role of Tektin-t, we generated mice with a mutation in the tektin-t gene. The homozygous mutant males were infertile, while the females were fully fertile. Sperm morphology and function were abnormal, ...
