Our benefits showed that the expression with the MEF2C mRNA and protein was decreased (Fig. 6B ) immediately after the overexpression of miR-935 (Fig. 6A). We also located that the decreased secretion of testosterone (Fig. 6E) slowed-down the proliferationrate. This was related towards the biological adjustments observed in R2C cells within a high-glucose environment. On the other hand, we observed that when the expression of miR-935 was knocked-down within a high-sugar medium, the above phenotypes were reversed. The above two sets of experiments indicated that higher glucose could induce the higher expression of miR-504 and miR-935. The high expression of miR-504 and miR-935 could be negatively regulated by targeting MEK5 and MEF2C, thereby inducing cell apoptosis. As such, slowing-down the proliferation of R2C cells would result in 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:Page 11 ofDiscussion The key findings of this study may very well be summarized in the following. The expression profile of testicular miRNAs differed drastically involving diabetic and typical rats.The differentially expressed miRNAs and mRNAs formed together a miRNA RNA regulatory network, which was involved in multiple signal transduction pathways in diabetic testicular damage. The miR-504 and miR-935 collaborative inhibition of 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 tiny, 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 using the 3-UTR of target mRNAs (Fabian and Sonenberg 2012). The miRNA pathways happen to be reported to become involved in diverse physiological and pathological processes, like self-renewal, proliferation, differentiation, and apoptosis. Important manage variables and biomarkers have been demonstrated to serve as clinically distinct biomarkers and therapeutic targets (Lu and Rothenberg 2018). Man.
