Abstract
This study aimed to investigate the protective effect of nicotinamide mononucleotide (NMN) on testicular spermatogenesis in aluminum chloride (AlCl3)-exposed rats and to elucidate the potential underlying mechanism. The results indicated that AlCl3-induced testicular damage, leading to reduced sperm quality, increased apoptosis, decreased cell proliferation, and impaired Sertoli cell function in rats. Additionally, glycolytic metabolism was observed to be hindered. However, after NMN treatment, there was a noticeable improvement in testicular damage among the rats, marked by increased sperm quality, reduced apoptosis, enhanced cell proliferation, improved Sertoli cell function, and an activated glycolytic metabolism. The findings of this study suggest that NMN alleviates testicular spermatogenesis impairment induced by AlCl3 exposure through the inhibition of spermatogenic cell apoptosis, promotion of spermatogenic cell proliferation, and activation of glycolytic pathways. The study contributes an experimental foundation for potential future clinical applications of NMN in cases of AlCl3-exposed spermatogenic dysfunction.

Stress Hormone Corticosterone Controls Metabolic Mitochondrial Performance and Inflammatory Signaling of In Vitro Cultured Sertoli Cells. Biomedicines 2022; 10:biomedicines10092331. [PMID: 36140432 PMCID: PMC9496023 DOI: 10.3390/biomedicines10092331] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 09/08/2022] [Accepted: 09/15/2022] [Indexed: 11/18/2022] Open
Abstract
Stress, as a physiological response, is a major factor that affects several processes, including reproductive functions. The main hormonal players of stress are cortisol (humans) and corticosterone (rodents). Sertoli cells (SCs), as key contributors for the testicular homeostasis maintenance, are extensively challenged by different hormones, with glucocorticoid corticosterone being the signaling modulator that may impact these cells at different levels. We aimed to characterize how corticosterone modulates SCs energy balance, putting the mitochondrial performance and signaling output in perspective as the cells can disperse to the surroundings. TM4 mouse SCs were cultured in the absence and presence of corticosterone (in nM: 20, 200, and 2000). Cells were assessed for extracellular metabolic fluxes, mitochondrial performance (cell respirometry, mitochondrial potential, and mitochondrial complex expressions and activities), and the expression of androgen and corticosteroid receptors, as well as interleukine-6 (IL-6) and glutathione content. Corticosterone presented a biphasic impact on the extracellular fluxes of metabolites. Low sub-physiological corticosterone stimulated the glycolytic activity of SCs. Still, no alterations were perceived for lactate and alanine production. However, the lactate/alanine ratio was decreased in a dose-dependent mode, opposite to the mitochondrial complex II activity rise and concurrent with the decrease of IL-6 expression levels. Our results suggest that corticosterone finely tuned the energetic profile of mouse SCs, with sub-physiological concentrations promoting glycolytic expenditure, without translating into cell redox power and mitochondrial respiratory chain performance. Corticosterone deeply impacted the expression of the pro-inflammatory IL-6, which may alter cell-to-cell communication in the testis, in the last instance and impact of the spermatogenic performance.

Ham J, Yun BH, Lim W, Song G. Folpet induces mitochondrial dysfunction and ROS-mediated apoptosis in mouse Sertoli cells. PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2021; 177:104903. [PMID: 34301364 DOI: 10.1016/j.pestbp.2021.104903] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 06/07/2021] [Accepted: 06/09/2021] [Indexed: 06/13/2023]
Abstract
Folpet is a phthalimide type of fungicide and has been used to control several crop diseases. Although it has adverse effects on the gastrointestinal tract, its mechanism and toxic effects on testis have not been demonstrated. In the present study, we elucidated the cytotoxic effect of folpet on the mouse Sertoli cell line, TM4. Our results revealed that folpet suppressed viability and proliferative capacity of TM4 cells and further inhibited 3D spheroid formation. Moreover, folpet impeded appropriate cell cycle progression and induced apoptotic cell death in TM4 cells. It disrupted the electrochemical gradient of mitochondria and calcium homeostasis in TM4 cells. Furthermore, endoplasmic reticulum stress-related proteins were activated in folpet-treated TM4 cells, and relative reactive oxygen species (ROS) production was also increased. N-acetylcysteine (NAC) treatment reinstated the folpet-induced ROS generation in TM4 cells. Additionally, NAC restored the proliferative capacity and reduced the apoptotic cells in folpet-treated TM4 cells. Collectively, we demonstrated that folpet causes ROS-mediated apoptotic cell death with mitochondrial dysfunction and calcium dysregulation in TM4 cells.
