We located that testosterone decreased with the increasing concentration of glucose, whereas the price of apoptosis improved using the escalating concentration of PPARĪ± Modulator custom synthesis glucose (Fig. 4I). These benefits indicated that glucose had a specific toxic impact on Leydig cells and could induce their apoptosis, in agreement with prior research, which recommended that this toxic impact is regulated by the concentration of glucose. In addition to, high levels of glucose were also discovered to induce a rise in miR-504 and miR-935 and the downregulation of MEK5 and MEF2C. This regulation was also demonstrated to be dependent on the concentration of sugars.miR504 inhibited the mTORC1 Activator web proliferation and promoted the apoptosis of Leydig cells by targeting MEK5 and MEF2CThe aforementioned experiments demonstrated the impact of higher glucose on the function of Leydig cells and their regulation by miR-504 and miR-935. Having said that, whether or not miR-504 and miR-935 are involved in the harm of R2C cells below the effect of higher glucose, and regardless of whether the downregulation of MEK5 and MEF2C is regulated by miR-504 and miR-935 remain unclear. Thus, we carried out a series of studies around the role of miR-504 and miR-935 in R2C cells. We first utilised oligos to overexpress miR-504 in standard culturedHu et al. Mol Med(2021) 27:Page 9 ofR2C cells, and knock-down the expression of miR-504 on R2C cells cultured inside a high-glucose atmosphere (30 mM) (Fig. 5A). Subsequent, we measured the expression of the 2 target genes, MEK5 and MEF2C, predicted by miR-504. Our benefits showed that the expression of MEK5 and MEF2C was considerably decreased, which was equivalent towards the expression of MEK5 and MEF2C within a high-glucose atmosphere. This lower 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 were consistent with theresults of MEK5 and MEF2C protein assays (Fig. 5DF). We then tested the cell phenotype of R2C. We 1st 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 located that after overexpressing miR-504, the proliferation price of R2C cells slowed own, whereas apoptosis was enhanced. Knockdown of miR-504 reversed theFig. 5 Modulation of proliferation and apoptosis of Leydig cells by mRNA targets of miR-504.
