Mechanisms of Guilu Erxian Oral Liquid in Ameliorating Kidney-Yang Deficiency Type Oligoasthenospermia in Rats Based on Proteomics
摘要
Abstract
Objective:To investigate the mechanisms of Guilu Erxian Oral Liquid(GLEX)in the treatment of oligoasthenospermia(OAS)of kidney-yang deficiency type.Methods:Fifty-six Sprague-Dawley(SD)rats were randomly divided into a control(C)group,a model(M)group,GLEX low-(GLEX-L),medium-(GLEX-M),and high-(GLEX-H)dose groups,a Wuzi Yanzong Pills(WZYZP)group,and a Levocarnitine Oral Solution(LOS)group,with 8 rats in each group.A kidney-yang deficiency type OAS model was established by intragastric administration of adenine(200 mg·kg-1·d-1)for 30 days.The treatment groups were administered GLEX-L,GLEX-M,and GLEX-H(2.7,5.4,and 10.8 mL·kg-1·d-1),WZYZP(1.269 mL·kg-1·d-1),and LOS(2.0 mL·kg-1·d-1),respectively.General conditions of rats were observed,and testicular and epididymal organ indices were calculated.Semen quality was assessed using a sperm analyzer.Serum hormone levels of the hypothalamic-pituitary-target gland axis were measured by enzyme-linked immunosorbent assay(ELISA).Testicular histomorphology was observed by hematoxylin-eosin(HE)staining,and Johnsen scores were calculated.Mitochondrial membrane potential(MMP)was detected by JC-1 flow cytometry.Data-independent acquisition(DIA)quantitative proteomics was used to screen key pathways involved in the therapeutic effects of GLEX on kidney-yang deficiency type OAS.Western blot(WB)was performed to validate the expression of key proteins,including Toll-like receptor 4(TLR4),inhibitor of nuclear factor kappa B(IκB),and nuclear factor kappa B p65(NF-κB p65),in rat testicular tissues.Results:Compared with the C group,rats in the M group exhibited lethargy,sluggishness,hair loss with huddling,loose stools,cold back,and slow weight gain.The testicular index was significantly increased(P<0.01).Sperm motility and rapid progressive motility were markedly decreased,whereas the sperm deformity rate was significantly increased(P<0.05,P<0.01).Serum levels of thyroid-stimulating hormone(TSH),follicle-stimulating hormone(FSH),luteinizing hormone(LH),and estradiol(E2)were significantly elevated(P<0.01),while no statistically significant differences were observed in corticotropin-releasing hormone(CRH),cortisol(Cor),or testosterone(T).Histological examination showed seminiferous tubule atrophy,exfoliation of spermatogenic cells,and reduced sperm count,with a marked reduction in Johnsen score(P<0.01).The MMP polymer/monomer ratio was significantly reduced(P<0.01).After treatment,the above indicators were improved to varying degrees.Proteomic analysis indicated that GLEX exerts its effects in tonifying kidney-yang and treating OAS mainly through the Toll-like receptor signaling pathway,autophagy-animal pathway,and NOD-like receptor signaling pathway.Validation of the TLR4/IκB/NF-κB pathway showed that,compared with the C group,the M group had TLR4 upregulation and enhanced phosphorylation of IκB-α and NF-κB p65 in testicular tissues(P<0.05,P<0.01).After GLEX intervention,the excessive expression of these proteins was significantly suppressed(P<0.05).Conclusion:GLEX can improve sperm quality,testicular tissue damage,mitochondrial function,and hormone levels in rats with kidney-yang deficiency type OAS.Its mechanism may be associated with the TLR4/IκB/NF-κB signaling pathway.关键词
