Our results showed that the expression from the MEF2C mRNA and protein was decreased (Fig. 6B ) after the overexpression of miR-935 (Fig. 6A). We also identified that the decreased secretion of testosterone (Fig. 6E) slowed-down the proliferationrate. This was related for the biological modifications observed in R2C cells in a high-glucose environment. Even so, we observed that when the expression of miR-935 was knocked-down in a high-sugar medium, the above phenotypes were reversed. The above 2 sets of experiments indicated that higher glucose could induce the high expression of miR-504 and miR-935. The high expression of miR-504 and miR-935 might be negatively regulated by targeting MEK5 and MEF2C, thereby inducing cell apoptosis. As such, slowing-down the proliferation of R2C cells would lead to the decreased secretion of testosterone.Fig. 6 Modulation of proliferation and apoptosis of Leydig cells by mRNA targets of miR-935.

Mol Med(2021) 27:Web page 11 ofDiscussion The key findings of this study may be summarized in the following. The expression profile of testicular miRNAs differed considerably involving diabetic and typical rats.The differentially expressed miRNAs and mRNAs formed collectively a miRNA RNA regulatory network, which was involved in numerous signal transduction pathways in diabetic testicular damage. The miR-504 and miR-935 collaborative inhibition on the classic survival pathway of MEK5-MEF2C in diabetic testis induced the apoptosis of Leydig cells and inhibited their cell proliferation, as shown in Fig. 7. MicroRNAs (miRNAs) are smaller, non-coding RNA molecules that function by regulating the expression of target genes by either inducing the degradation or inhibiting the translation of mRNAs via imperfectbase-pairing with all the 3-UTR of target mRNAs (Fabian and Sonenberg 2012). The miRNA pathways have already been reported to become involved in diverse physiological and pathological processes, like self-renewal, proliferation, differentiation, and apoptosis. Important manage variables and biomarkers happen to be demonstrated to serve as clinically distinct biomarkers and therapeutic targets (Lu and Rothenberg 2018). Man.
