[PMID: 38069413 PMCID: PMC10707026 DOI: 10.3390/ijms242317091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 11/30/2023] [Accepted: 12/02/2023] [Indexed: 12/18/2023] Open
Abstract
Artificial insemination (AI) with liquid-stored semen is the most prevalent and efficient assisted reproduction technique in the modern pork industry. Pyruvate dehydrogenase complex component X (PDHX) was demonstrated to be associated with sperm metabolism and affected the boar sperm viability, motility, and fertility. Pyruvate Dehydrogenase Kinases (PDKs) are the key metabolic enzymes that regulate pyruvate dehydrogenase complex (PDHC) activity and also the conversion from glycolysis to oxidative phosphorylation. In the present study, two PDK inhibitors, Dichloroacetate (DCA) and Phenylbutyrate (4-PBA), were added to an extender and investigated to determine their regulatory roles in liquid-stored boar sperm at 17 °C. The results indicated that PDK1 and PDK3 were predominantly located at the head and flagella of the boar sperm. The addition of 2 mM DCA and 0.5 mM 4-PBA significantly enhanced the sperm motility, plasma membrane integrity (PMI), mitochondrial membrane potential (MMP), and ATP content. In addition, DCA and 4-PBA exerted their effects by inhibiting PDK1 and PDK3, respectively. In conclusion, DCA and 4-PBA were found to regulate the boar sperm metabolic activities via PDK1 and PDK3. These both can improve the quality parameters of liquid-stored boar sperm, which will help to improve and optimize liquid-stored boar semen after their addition in the extender.

Seyedasgari F, Asadi B, Kim E. Seminal plasma modulates post-thaw longevity and motility of frozen sperm in dromedary camel. Anim Biosci 2023; 36:1821-1830. [PMID: 37641835 PMCID: PMC10623026 DOI: 10.5713/ab.23.0136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 06/21/2023] [Accepted: 07/19/2023] [Indexed: 08/31/2023] Open
Abstract
OBJECTIVE This study investigated the effect of adding seminal plasma to frozen-thawed semen on the quality of sperm and pregnancy following insemination in dromedary camels. METHODS In experiment 1, the frozen-thawed semen from 9 collections (3 bulls) was further diluted with either the base extender or homologous seminal plasma (HSP). In the second experiment, a pooled sample of frozen-thawed semen was diluted with either seminal plasma from another three bulls. Live percentage, total and progressive motility, functional and acrosome integrity, and sperm kinematics were evaluated at 15, 60, and 120 minutes post-thawing and compared to the non-treated control. In experiment 3, frozen semen was used to inseminate camels in the following experimental groups: 1-Single insemination with double dose undiluted frozen semen (n = 9); 2-Re-insemination in 6 hours with undiluted semen (n = 13); 3-Single insemination with HSP treated sperm (n = 14). RESULTS Frozen-thawed sperm diluted in HSP or the non-homologous seminal plasma from Bull C indicated an improvement in all parameters after 1 hour post-thawing incubation (p<0.05). The proportion of total and progressively motile sperm did not drop significantly at 60 minutes post-thawing when diluted with the seminal plasma of Bull C (p>0.05). Double insemination with nontreated sperm and single insemination with HSP-treated sperm resulted in similar pregnancy rates (15.3% vs 21.4%, p>0.05). None of the camels conceived with double-dose single insemination of nontreated sperm. CONCLUSION Seminal plasma improves sperm longevity and motility after thawing in dromedary camel with a significant between-bull variation in effect. Low post-thaw sperm longevity might be the cause behind the low pregnancy rates in frozen semen insemination of dromedary camels.

Possible mechanisms involved in the testicular-protective property of quercetin in rats exposed to endosulfan toxicity. PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2022; 188:105224. [PMID: 36464344 DOI: 10.1016/j.pestbp.2022.105224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 07/24/2022] [Accepted: 09/01/2022] [Indexed: 06/17/2023]
Abstract
The study investigated the effects of quercetin and putative mechanisms involved against endosulfan-testicular impairments in rats. Rats were allotted into five treatment groups (n = 5). Groups 1-2 had normal saline and maize oil (vehicle) (10 mL/kg), group 3 received quercetin (20 mg/kg), 4-5 had endosulfan (5 mg/kg, p.o) orally for 28 days. However, from days 14-28, group 4 received an additional dose of vehicle (10 mL/kg, p.o./day), while group 5 received quercetin (20 mg/kg, p.o./day). Thereafter, blood samples and testes were harvested for markers of cholinergic, hormonal and testicular oxido-nitrergic, inflammatory, apoptosis and proton pump ATPase activities. Also, testicular histopathological changes were also evaluated alongside with germ cell count, testicular injury and spermatogenesis score. Quercetin increased testicular/body weights and spermatogenesis, androgenic hormones (follicle stimulating hormones, FSH; luteinizing hormone, LH; testosterone), acetylcholinesterase levels and attenuated altered membrane integrity, DNA fragmentation, increased caspases-3 levels in rats exposed to endosulfan. Moreover, quercetin increased testicular B-cell lymphoma-2 (Bcl-2), Bcl-2 associated x-protein (Bax) and proton pump adenosine trisphosphate (ATPase) and sialic acid levels. Of note, quercetin reversed endosulfan-mediated increased malondialdehyde, nitrite, peroxynitrite formation, 8-hydroxy-2'-deoxyguanosine and lowered antioxidant enzymes in the testes. The increased levels of testicular myeloperoxidase (MPO), tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) by endosulfan were also reduced by quercetin administration. Additionally, quercetin attenuate endosulfan-induced testicular histopathological changes of rats. Our findings showed that quercetin significantly inhibited endosulfan-induced testicular damage and altered spermatogenesis through inhibition of oxido-nitrergic pathway, inflammatory mediators, apoptosis, acetylcholinesterase activity and enhancement of testicular hormones and improvement in testicular ATPase activity.
