We identified that testosterone decreased together with the rising concentration of glucose, whereas the price of apoptosis increased using the growing concentration of mAChR5 Agonist medchemexpress glucose (Fig. 4I). These outcomes indicated that glucose had a particular toxic effect on Leydig cells and could induce their apoptosis, in agreement with previous studies, which recommended that this toxic effect is regulated by the concentration of glucose. Apart from, high levels of glucose had been also discovered to induce an increase in miR-504 and miR-935 along with the downregulation of MEK5 and MEF2C. This regulation was also demonstrated to be dependent around the concentration of sugars.miR504 inhibited the proliferation and promoted the apoptosis of Leydig cells by targeting MEK5 and MEF2CThe aforementioned experiments demonstrated the impact of high glucose on the function of Leydig cells and their regulation by miR-504 and miR-935. On the other hand, whether or not miR-504 and miR-935 are involved in the harm of R2C cells beneath the effect of high glucose, and whether or not the downregulation of MEK5 and MEF2C is regulated by miR-504 and miR-935 stay unclear. As a result, we carried out a series of research on the role of miR-504 and miR-935 in R2C cells. We initial used oligos to overexpress miR-504 in normal culturedHu et al. Mol Med(2021) 27:Web page 9 ofR2C cells, and knock-down the expression of miR-504 on R2C cells cultured in a high-glucose environment (30 mM) (Fig. 5A). Next, we measured the expression on the two target genes, MEK5 and MEF2C, predicted by miR-504. Our results showed that the expression of MEK5 and MEF2C was considerably decreased, which was related for the expression of MEK5 and MEF2C within a high-glucose atmosphere. This decrease within the expression of MEK5 and MEF2C triggered by higher glucose was reversed when we knocked-down the expression of miR-504 in R2C cells cultured with higher glucose (Fig. 5B, C), The above trends had been consistent with theresults of MEK5 and MEF2C protein assays (Fig. 5DF). We then tested the cell phenotype of R2C. We initially detected the secretion of testosterone in R2C cells. Our benefits showed that the overexpression of miR-504 could inhibit the secretion of cell testosterone, whereas knocking-down the expression of miR-504 could partially recover the high-glucose-induced weakened secretion of testosterone by R2C cells. Subsequently, we tested the proliferation and apoptosis of R2C cells and discovered that just after overexpressing miR-504, the proliferation price of R2C cells slowed own, whereas apoptosis was enhanced. Knockdown of miR-504 reversed theFig. five Modulation of proliferation and apoptosis of Leydig cells by mRNA targets of miR-504.
