Autophagy, a critical element in the aging male reproductive disorders and prostate cancer: a therapeutic point of view. Reprod Biol Endocrinol 2023; 21:88. [PMID: 37749573 PMCID: PMC10521554 DOI: 10.1186/s12958-023-01134-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Accepted: 09/01/2023] [Indexed: 09/27/2023] Open
Abstract
Autophagy is a highly conserved, lysosome-dependent biological mechanism involved in the degradation and recycling of cellular components. There is growing evidence that autophagy is related to male reproductive biology, particularly spermatogenic and endocrinologic processes closely associated with male sexual and reproductive health. In recent decades, problems such as decreasing sperm count, erectile dysfunction, and infertility have worsened. In addition, reproductive health is closely related to overall health and comorbidity in aging men. In this review, we will outline the role of autophagy as a new player in aging male reproductive dysfunction and prostate cancer. We first provide an overview of the mechanisms of autophagy and its role in regulating male reproductive cells. We then focus on the link between autophagy and aging-related diseases. This is followed by a discussion of therapeutic strategies targeting autophagy before we end with limitations of current studies and suggestions for future developments in the field.

Mitochondrial defects caused by PARL deficiency lead to arrested spermatogenesis and ferroptosis. eLife 2023; 12:e84710.

Abstract
Impaired spermatogenesis and male infertility are common manifestations associated with mitochondrial diseases, yet the underlying mechanisms linking these conditions remain elusive. In this study, we demonstrate that mice deficient for the mitochondrial intra-membrane rhomboid protease PARL, a recently reported model of the mitochondrial encephalopathy Leigh syndrome, develop early testicular atrophy caused by a complete arrest of spermatogenesis during meiotic prophase I, followed by degeneration and death of arrested spermatocytes. This process is independent of neurodegeneration. Interestingly, genetic modifications of PINK1, PGAM5, and TTC19 - three major substrates of PARL with important roles in mitochondrial homeostasis - fail to reproduce or modify this severe phenotype, indicating that the spermatogenic arrest arises from distinct molecular pathways. We further observed severe abnormalities in mitochondrial ultrastructure in PARL-deficient spermatocytes, along with prominent electron transfer chain defects, disrupted coenzyme Q (CoQ) biosynthesis, and metabolic rewiring. These mitochondrial defects are associated with a germ cell-specific decrease in GPX4 expression leading arrested spermatocytes to ferroptosis - a regulated cell death modality characterized by uncontrolled lipid peroxidation. Our results suggest that mitochondrial defects induced by PARL depletion act as an initiating trigger for ferroptosis in primary spermatocytes through simultaneous effects on GPX4 and CoQ - two major inhibitors of ferroptosis. These findings shed new light on the potential role of ferroptosis in the pathogenesis of mitochondrial diseases and male infertility warranting further investigation.

Abstract
As the main component of seminiferous tubules, Sertoli cells are in close contact with germ cells and generate niche signals, which exhibit pivotal functions in spermatogenesis and male fertility. However, the regulatory mechanisms of Sertoli cell-germline interactions (SGIs) in the testes of neonatal mice (NM) remain largely unclear. Previously, we identified spermidine/spermine N1-acetyl transferase 2 (SAT2) and stromal interaction molecule 1 (STIM1) to be potential regulators of testicular cord formation via comparative proteomics analysis. Here, we demonstrated a novel role of SAT2 for SGIs during testicular development in NM. Testicular explants lacking SAT2 affected the mislocation, but not the quantity, of Sertoli cells, which led to maintenance defects in spermatogonial stem cells (SSCs). Interestingly, SAT2 was essential for the migration of TM4 cells, a Sertoli cell line. Mechanistically, SAT2 was able to bind STIM1, repress its expression, and regulate homeostasis of a reactive oxygen species/wingless type (WNT)/β-catenin pathway in NM testes. Collectively, our study identified that SAT2 was able to regulate SGIs via a STIM1-mediated WNT signaling pathway.

stallions. JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY 2022; 64:654-670. [PMID: 35969700 PMCID: PMC9353347 DOI: 10.5187/jast.2022.e57] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 06/21/2022] [Accepted: 06/22/2022] [Indexed: 11/20/2022]
Abstract
Spermatogenesis and testis development are highly structured physiological
processes responsible for post-pubertal fertility in stallions. Spermatogenesis
comprises spermatocytogenesis, meiosis, and spermiogenesis. Although germ cell
degeneration is a continuous process, its effects are more pronounced during
spermatocytogenesis and meiosis. The productivity and efficiency of
spermatogenesis are directly linked to pubertal development, degenerated germ
cell populations, aging, nutrition, and season of the year in stallions. The
multiplex interplay of germ cells with somatic cells, endocrine and paracrine
factors, growth factors, and signaling molecules contributes to the regulation
of spermatogenesis. A cell-to-cell communication within the testes of these
factors is a fundamental requirement of normal spermatogenesis. A noteworthy
development has been made recently on discovering the effects of different
somatic cells including Leydig, Sertoli, and peritubular myoid cells on
manipulation the fate of spermatogonial stem cells. In this review, we discuss
the self-renewal, differentiation, and apoptotic roles of somatic cells and the
relationship between somatic and germ cells during normal spermatogenesis. We
also summarize the roles of different growth factors, their
paracrine/endocrine/autocrine pathways, and the different cytokines associated
with spermatogenesis. Furthermore, we highlight important matters for further
studies on the regulation of spermatogenesis. This review presents an insight
into the mechanism of spermatogenesis, and helpful in developing better
understanding of the functions of somatic cells, particularly in stallions and
would offer new research goals for developing curative techniques to address
infertility/subfertility in stallions.

Abstract
Background A major goal of spermiation is to degrade the apical ectoplasmic specialization (ES) junction between Sertoli cells and elongating spermatids in preparation for the eventual disengagement of spermatids into the lumen. E3 ubiquitin ligases mediate the process of ubiquitination and the subsequent proteasomal degradation, but their specific role during spermiation remains largely unexplored. Methods Ankyrin repeat and SOCS box protein 17 (Asb17)-knockout mice were generated via a CRISPR/Cas9 approach. Epididymal sperm parameters were assessed by a computer-assisted sperm analysis (CASA) system, and morphological analysis of testicular tissues were performed based on histological and immunostaining staining, and transmission electron microscopy (TEM). The interactions between ASB17 and Espin (ESPN) were predicted by HawkDock server and validated through protein pull-down and immunoprecipitation assays. Results We report that ASB17, an E3 ligase, is required for the completion of spermiation and that mice lacking Asb17 are oligozoospermic owing to spermiation failure. ASB17-deficient mice are fertile; however, spermatids exhibit a disorganized ES junction, resulting in retention within the seminiferous epithelium. Mechanistically, ASB17 deficiency leads to excess accumulation of ESPN, an actin-binding essential structural component of the ES. We determined that ASB17 regulates the removal of the ES through ubiquitin mediated protein degradation of ESPN. Conclusions In summary, our study describes a role for ASB17 in the regulation of cell-cell junctions between germ cells and somatic cells in the testis. These findings establish a novel mechanism for the regulatory role of E3 ligases during spermatogenesis.

Abstract
Spermatogonia are accountable for spermatogenesis and male fertility, but the underlying mechanisms involved in spermatogonia maintenance are not clear. B lymphoma Mo-MLV insertion region 1 (BMI1) is a key component of epigenetic silencers. BMI1 is essential for stem-cell maintenance. Here, we attempted to uncover the role of BMI1 in spermatogonia maintenance using a mouse spermatogonia cell line (GC-1) and Bmi1-knockout (KO) mouse model. We showed that BMI1 promoted the proliferation and inhibited apoptosis of GC-1 cells. Mechanistically, we present in vitro and in vivo evidence to show that BMI1 binds to the promoter region of the Protein tyrosine phosphatase receptor type M (PTPRM) gene, thereby driving chromatin remodeling and gene silencing. Knockdown of Ptprm expression significantly improved spermatogonia proliferation in BMI1-deficient GC-1 cells. Collectively, our data show, for the first time, an epigenetic mechanism involving in BMI1-mediated gene silencing in spermatogonia maintenance, and provide potential targets for the treatment of male infertility.
