Abstract
AIM This study focused on the anti-oxidant and anti-apoptotic effects of CoQ10 in ovaries exposed to pelvic radiation. METHODS Thirty-two female rats were randomly assigned into four groups. Group I (control group), Group II: Only 2 Gy pelvic x-ray irradiation (IR) was administered as a single fractioned dose. Group III: 30 mg/kg CoQ10 was administered by oral gavage +2 Gy pelvic IR. Group IV: 150 mg/kg CoQ10 was administered by oral gavage +2 Gy pelvic IR. CoQ10 treatment was started 7 days before pelvic IR and completed 7 days later. The rats in Group III and IV were treated with CoQ10 for a total of 14 days. RESULTS Histopathological analysis showed severe damage to the ovarian tissue in the radiation group, while both doses of CoQ10 showed normal histological structure. Likewise, while there was a high level of staining in the IR group for necrosis and apoptosis, the CoQ10 treated ones were like the control group. Tissue Malondialdehyde (MDA) levels were like the control group in the low-dose CoQ10 group, while the MDA levels of the high dose CoQ10 group were similar to the radiation group. CONCLUSION Usage of low-dose CoQ10 has a radioprotective effect on radiation-induced ovarian damage. Although the use of high doses is morphologically radioprotective, no antioxidative effect was observed in the biochemical evaluation.

Abstract
Spermiogenesis, a sperm-activation step, is crucial for the transformation of immotile spermatids into motile sperm. Though membrane transport of ions and molecules across the sperm plasma membrane has been implicated in this process, the full repertoire of transporters involved, and their respective substrates, is unclear. Here, we report that the major facilitator superfamily transporter SPIN-4/Spinster governs efficient spermiogenesis and fertility in the hermaphrodite nematode Caenorhabditis elegans. Unlike other C. elegans Spinster paralogs, SPIN-4 is germline-expressed. Moreover, SPIN-4 expression is gamete-specific; it is strongly expressed in developing sperm, where it localizes to the plasma membrane, but it is absent from oocytes. Consistent with these expression data, we demonstrate that knocking out spin-4 impairs sperm development, leading to the formation of non-motile sperm that lack pseudopodia. Consequently, hermaphrodites homozygous for the spin-4(knu1099) knockout allele show extensive sperm wasting and reduced self-progeny. We observe similar defects when we genetically inhibit production of sphingosine-1-phosphate, a lipid molecule that stimulates cell motility when exported extracellularly by Spinster homologs in other contexts. Remarkably, extracellular supplementation with sphingosine-1-phosphate rescues sperm activation and motility in the absence of SPIN-4, suggesting that Spinster-dependent efflux of sphingosine-1-phosphate plays a key role in sperm mobilization. These findings identify a new signaling mechanism in C. elegans spermiogenesis entailing Spinster and sphingosine-1-phosphate.

Roles of follicle stimulating hormone and sphingosine 1-phosphate co-administered in the process in mouse ovarian vitrification and transplantation. J Ovarian Res 2023; 16:173. [PMID: 37620938 PMCID: PMC10463983 DOI: 10.1186/s13048-023-01206-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 06/16/2023] [Indexed: 08/26/2023] Open
Abstract
Some major challenges of ovarian tissue vitrification and transplantation include follicle apoptosis induced by cryopreservation and ischemia-reperfusion injury, as well as ovarian follicle loss during post-transplantation. This research aimed to investigate the protective effects and underlying mechanisms of follicle-stimulating hormone (FSH) and Sphingosine-1-phosphate (S1P) on vitrified and post-transplantation ovaries. Ovaries from 21-day-old mice were cryopreservation by vitrification with 0.3 IU/mL FSH, 2 µM S1P, and 0.3 IU/mL FSH + 2 µM S1P, respectively, for follicle counting and detection of apoptosis-related indicators. The results demonstrated that FSH and S1P co-intervention during the vitrification process could preserve the primordial follicle pool and inhibit follicular atresia by suppressing cell apoptosis. The thawed ovaries were transplanted under the renal capsule of 6-8 week-old ovariectomized mice and removed 24 h or 7 days after transplantation. The results indicated that FSH and S1P co-intervention can inhibit apoptosis and autophagy in ovaries at 24 h after transplantation, and promote follicle survival by up-regulating Cx37 and Cx43 expression, enhanced angiogenesis in transplanted ovaries by promoting VEGF expression, as well as increased the E2 levels to restore ovarian endocrine function at 7 days after transplantation. The hypoxia and ischemia cell model was established by CoCl2 treatment for hypoxia in human granulosa-like tumor cell line (KGN), as well as serum-free culture system was used for ischemia. The results confirmed that ischemia-hypoxia-induced apoptosis in ovarian granulosa cells was reduced by FSH and S1P co-intervention, and granulosa cell autophagy was inhibited by up-regulating the AKT/mTOR signaling pathway. In summary, co-administration of FSH and S1P can maintain ovarian survival during ovarian vitrification and increase follicle survival and angiogenesis after transplantation.

Reprod Toxicol 2023; 115:49-55. [PMID: 36503164 DOI: 10.1016/j.reprotox.2022.12.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 12/01/2022] [Accepted: 12/06/2022] [Indexed: 12/13/2022]
Abstract
Ferroptosis is a form of cell death caused by the accumulation of lipid peroxidation products due to abnormal iron metabolism. However, it remains unknown whether ferroptosis participates in the process of radiation-induced ovarian injury. Sphingosine-1-phosphate (S1P) is an important bioactive sphingolipid that has a protective effect on ovarian injury. The present study aims to determine whether X-ray radiation induces ferroptosis in the ovarian granulosa KGN cell line, and explore the potential effect of S1P and its mechanism in radiation-induced ferroptosis. The results indicated that irradiation reduced the viability of KGN cells, altered the mitochondrial morphology, induced the intracellular accumulation of iron ions, increased oxidative stress, and induced lipid peroxidation. Furthermore, the radiation exposure triggered the ferroptosis in KGN cells. S1P can alleviate radiation-induced ferroptosis. Furthermore, the protective effect of S1P was reversed after the application of siRNA to interfere with the glutathione peroxidase 4 expression. Ferroptosis might be pervasive in radiation-induced ovarian injury, and S1P may serve as a potential therapeutic approach to protect against the toxic effect of radiation in female gonads by inhibiting ferroptosis.

Analysis on the desert adaptability of indigenous sheep in the southern edge of Taklimakan Desert. Sci Rep 2022; 12:12264. [PMID: 35851076 PMCID: PMC9293982 DOI: 10.1038/s41598-022-15986-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Accepted: 07/04/2022] [Indexed: 11/25/2022] Open
Abstract
The southern margin of the Taklimakan Desert is characterized by low rainfall, heavy sandstorms, sparse vegetation and harsh ecological environment. The indigenous sheep in this area are rich in resources, with the advantages of perennial estrus and good resistance to stress in most sheep. Exploring the molecular markers of livestock adaptability in this environment will provide the molecular basis for breeding research to cope with extreme future changes in the desert environment. In this study, we analyzed the population genetic structure and linkage imbalance of five sheep breeds with three different agricultural geographic characteristics using four complementary genomic selection signals: fixation index (FST), cross-population extended haplotype homozygosity (xp-EHH), Rsb (extended haplotype homozygosity between-populations) and iHS (integrated haplotype homozygosity score). We used Illumina Ovine SNP 50K Genotyping BeadChip Array, and gene annotation and enrichment analysis were performed on selected regions of the obtained genome. The ovary of Qira Black sheep (Follicular phase, Luteal phase, 30th day of pregnancy, 45th day of pregnancy) was collected, and the differentially expressed genes were screened by transcriptomic sequencing. Genome-wide selective sweep results and transcriptome data were combined for association analysis to obtain candidate genes associated with perennial estrus and stable reproduction. In order to verify the significance of the results, 15 resulting genes were randomly selected for fluorescence quantitative analysis. The results showed that Dolang sheep and Qira Black sheep evolved from Kazak sheep. Linkage disequilibrium analysis showed that the decay rate of sheep breeds in the Taklimakan Desert was higher than that in Yili grassland. The signals of FST, xp-EHH, Rsb and iHS detected 526, 332, 308 and 408 genes, respectively, under the threshold of 1% and 17 overlapping genes under the threshold of 5%. A total of 29 genes were detected in association analysis of whole-genome and transcriptome data. This study reveals the genetic mechanism of perennial estrus and environmental adaptability of indigenous sheep breeds in the Taklimakan Desert. It provides a theoretical basis for the conservation and exploitation of genetic resources of indigenous sheep breeds in extreme desert environment. This provides a new perspective for the quick adaptation of sheep and other mammals to extreme environments and future climate changes.

Abstract
Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid metabolite. The past decade has witnessed exponential growth in the field of S1P research, partly attributed to drugs targeting its receptors or kinases. Accumulating evidence indicates that changes in the S1P axis (i.e., S1P production, transport, and receptors) may modify metabolism and eventually mediate metabolic diseases. Dysfunction of the mitochondria on a master monitor of cellular metabolism is considered the leading cause of metabolic diseases, with aberrations typically induced by abnormal biogenesis, respiratory chain complex disorders, reactive oxygen species overproduction, calcium deposition, and mitophagy impairment. Accordingly, we discuss decades of investigation into changes in the S1P axis and how it controls mitochondrial function. Furthermore, we summarize recent scientific advances in disorders associated with the S1P axis and their involvement in the pathogenesis of metabolic diseases in humans, including type 2 diabetes mellitus and cardiovascular disease, from the perspective of mitochondrial function. Finally, we review potential challenges and prospects for S1P axis application to the regulation of mitochondrial function and metabolic diseases; these data may provide theoretical guidance for the treatment of metabolic diseases.
