Abstract
Asthenoteratozoospermia is a common underlying cause of male infertility, with dynein dysfunction playing an important role in the aetiology of the condition. Dysfunction in certain dynein proteins has been implicated in asthenoteratozoospermia, while others exclusively induce asthenozoospermia in the absence of overt morphological abnormalities in the sperm. Dynein axonemal heavy chain 10 (DNAH10), an inner dynein arm heavy chain protein, was identified as being associated with asthenoteratozoospermia in our previous studies. However, the mechanism through which DNAH10 contributes to this condition remains unclear. In this study, we demonstrated that DNAH10 deficiency leads to abnormal morphology of the sperm head and flagella. Additionally, DNAH10 dysfunction leads to impaired manchette function and aberrant localisation of axonemal proteins. Mechanistically, ubiquitin carboxyl-terminal hydrolase L3 (UCHL3) binds to Parkin co-regulated gene protein (PACRG) and stabilises it via deubiquitination. In this process, DNAH10 exerts a bridging effect, enhancing the interaction between the UCHL3-PACRG complex to facilitate their involvement in manchette function. Collectively, this study demonstrated the function of DNAH10 in intra-manchette transport, providing important guidance for genetic diagnosis and prognosis in patients with infertility.
期刊介绍：
Development’s scope covers all aspects of plant and animal development, including stem cell biology and regeneration. The single most important criterion for acceptance in Development is scientific excellence. Research papers (articles and reports) should therefore pose and test a significant hypothesis or address a significant question, and should provide novel perspectives that advance our understanding of development. We also encourage submission of papers that use computational methods or mathematical models to obtain significant new insights into developmental biology topics. Manuscripts that are descriptive in nature will be considered only when they lay important groundwork for a field and/or provide novel resources for understanding developmental processes of broad interest to the community.
Development includes a Techniques and Resources section for the publication of new methods, datasets, and other types of resources. Papers describing new techniques should include a proof-of-principle demonstration that the technique is valuable to the developmental biology community; they need not include in-depth follow-up analysis. The technique must be described in sufficient detail to be easily replicated by other investigators. Development will also consider protocol-type papers of exceptional interest to the community. We welcome submission of Resource papers, for example those reporting new databases, systems-level datasets, or genetic resources of major value to the developmental biology community. For all papers, the data or resource described must be made available to the community with minimal restrictions upon publication.
To aid navigability, Development has dedicated sections of the journal to stem cells & regeneration and to human development. The criteria for acceptance into these sections is identical to those outlined above. Authors and editors are encouraged to nominate appropriate manuscripts for inclusion in one of these sections.
