Abstract
Prolonging the reproductive lifespan is beneficial for preserving the physical and psychological health of women. The transplantation of mesenchymal stem cell (MSC)‑derived exosomes (MSC‑Exos) has been reported to be a promising regenerative therapeutic strategy for restoring the function of aging ovaries. The present study thus evaluated the therapeutic efficacy of exosomes derived from human umbilical cord‑MSCs (hUCMSC‑Exos) in a mouse model of natural ovarian aging (NOA), and further investigated the role of exosomal microRNAs (miRNAs/miRs) in the mechanisms of this creative therapy. Specifically, following the administration of hUCMSC‑Exos in mice with NOA, ovarian function was found to improve, as indicated by the restoration of follicle numbers and hormone levels. These exosomes were found to exhibit the ability to inhibit PTEN expression and suppress apoptosis both in vivo and in vitro. Subsequently, miRNA sequencing of the exosomes was performed, following which bioinformatics analysis was used to identify the highly expressed miRNAs that are capable of targeting PTEN expression. Through high‑throughput sequencing and molecular analyses, miR‑21‑5p was found to be the highest in ranking in terms of expression, suggesting that hUCMSC‑Exos can preserve ovarian function by suppressing PTEN expression to inhibit apoptosis by delivering miR‑21‑5p. On the whole, the results of the present study suggest that the application of exosomes can be used to restore ovarian function in mice with NOA. These positive findings also suggest that the transplantation of exosomes derived from MSCs holds promise as an agent against ovarian aging.

Abstract
Inflammation and oxidative stress are key steps in the progression of non‑alcoholic steatohepatitis (NASH). Intervention in these two processes will therefore benefit NASH treatment. Peroxisome proliferator‑activated receptor γ (PPARγ), as a multiple functional transcription factor, has been reported to be involved in the prevention of NASH progression. However, the mechanism by which PPARγ prevents NASH remains to be elucidated. The present study demonstrated that the level of PPARγ was inversely correlated with that of microRNA (miRNA/miRs)‑21‑5p in both mice and humans with NASH. Activation of PPARγ inhibited lipid droplet accumulation, hepatic inflammation and oxidative stress by downregulating miR‑21‑5p in an in vitro model. Luciferase reporter and chromatin immunoprecipitation assays demonstrated that PPARγ suppressed transcriptional activity of miR‑21‑5p and bound to miR‑21‑5p promoter region. Furthermore, PPARγ downregulated miR‑21‑5p while miR‑21‑5p upregulated secreted frizzled‑related protein 5 (SFRP5) by targeting the 3'‑UTR of its mRNA. In vivo experiments revealed that PPARγ repressed inflammation and oxidative stress and miR‑21‑5p expression while increased SFRP5 level in a NASH mouse model. In summary, PPARγ attenuates inflammation and oxidative stress in NASH by modulating the miR‑21‑5p/SFRP5 pathway, thus holding promise of a new target for NASH treatment.
