Abstract
Heat stress (HS) is a potential harmful factor for male reproduction. However, the effect of HS on Sertoli cells is largely unknown. In this study, the metabolic changes in Sertoli cell line were analyzed after HS treatment. Metabolomic analysis revealed that carnitine, 2-hydroxy palmitic acid, nicotinic acid, niacinamide, adenosine monophosphate, glutamine and creatine were the key changed metabolites. We found the expression levels of BTB factors (Connexin43, ZO-1, Vimentin, Claudin1, Claudin5) were disrupted in TM-4 cells after HS treatment, which were recovered by the addition of carnitine. RT-PCR indicated that the mRNA levels of inflammatory cytokines (IL-1α, IL-1β, IL-6) were increased after HS treatment, and their related miRNAs (miR-132, miR-431, miR-543) levels were decreased. Our metabolomic data provided a novel understanding of metabolic changes in male reproductive cells after HS treatment and revealed that HS-induced changes of BTB factors and inflammatory status might be caused by the decreased carnitine after HS treatment.
