Mitigating chemotherapy-induced granulosa cell damage: role of hUCMSC-EVs in regulating the lncRNA HCP5-miR-20a-5p-YAP1 network.

ABSTRACT: The substantial apprehension facing young cancer patients revolves around the onset of chemotherapy-induced premature ovarian failure (POF), primarily linked to damage inflicted upon granulosa cells (GCs). The inquiry delves into the protective role of extracellular vesicles (EVs) derived from human umbilical cord mesenchymal stem cells (hUCMSCs) in mitigating chemotherapy-induced ovarian failure. Specifically, we investigated the mechanism by which hUCMSC-EVs deliver the long non-coding RNA (lncRNA) HCP5 to regulate DNA damage repair in GCs via the miR-20a-5p/YAP1 axis. The detection of differentially expressed lncRNAs in GC injury resulting from cyclophosphamide (CP) was conducted through transcriptome sequencing. hUCMSC-EVs were isolated, characterized, and co-cultured with CP-injured G
