Popis: Background Adipose derived stem cells (ADSCs) have the property to differentiate into neuron-like cells, which may provide a novel insight for the restoration of erectile dysfunction (ED) mainly induced by cavernous nerve injury. Icariside II (ICA II) has been reported to play a key role in the regulation of erectile function via stimulating the differentiation of ADSCs to Schwann Cells (SCs). However, the function and molecular mechanisms of ICA II in ED remains to be further clarified. Methods The expression of S100, P75, GDNF and miR-33 was detected by qRT-PCR. And the relative proteins expression was determined by western blot. Cell viability was measured by Cell Counting Kit-8 (CCK-8) assay. Bioinformatics, luciferase reporter and RNA immunoprecipitation (RIP) assays were performed to verify the interaction between miR-33 and GDNF. Intracavernosal pressure (ICP), the ratio of ICP and mean arterial pressure (MAP), as well as nNOS expression were examined to evaluate the erectile function of SD rats with bilateral cavernous nerve injury (BCNI). Results ICA II and miR-33 respectively promoted and inhibited the differentiation of ADSCs to SCs. MiR-33 could negatively regulate P75 and GDNF expression. ICA II exerted promotion effects on differentiation of ADSCs to SCs via regulating miR-33. GDNF was identified to be a target of miR-33. MiR-33 overexpression abrogated the stimulatory effect of ICA II on ADSCs' differentiation, which was blocked by GDNF overexpression. treated with ICA II recovered the erectile function of BCNI model rats through regulation of miR-33. Conclusion ICA II contributed to the differentiation of ADSCs to SCs viamiR-33/GDNF axis, contributing to the recovery of erectile function in BCNI rats.
