Abstract
Daucosterol is a phytosterol glycoside with hepatoprotective properties. The objective of the present study was to confirm the role of daucosterol in liver failure. Exosomes were isolated from primary mouse umbilical cord mesenchymal stem cells (UCMSCs). A liver failure mouse model was generated by injecting lipopolysaccharide/D-galactosamine. Mice were treated with exosomes alone or in combination with daucosterol (5, 10, or 20 mg/kg). Liver tissue damage was examined by hematoxylin-eosin, Masson's trichrome, and TUNEL staining. The levels of genes, proteins, and inflammatory factors were determined using real-time qPCR, western blotting, and enzyme-linked immunosorbent assay, respectively. Compared with normal mice, we noted severe damage, fibrosis, and apoptosis in the liver tissues of liver failure-induced mice. UCMSC-derived exosomes effectively alleviated hepatic damage in the mouse model. Compared with exosome treatment alone, exosomes combined with daucosterol significantly and dose-dependently reduced pathological changes in model mice. Exosome treatment alone or combined with daucosterol also markedly decreased the liver index and reduced levels of alanine aminotransferase, aspartate aminotransferase, tumor necrosis factor-α, interleukin (IL)-1β, and IL-6 in model mice. Exosome treatment alone or combined with daucosterol suppressed mRNA expression levels of IL-6 and signal transducer and activator of transcription (STAT3) and STAT3 protein expression in model mice. Our findings revealed that treatment with daucosterol combined with UCMSC-derived exosomes was superior to exosomes alone for alleviating hepatic damage in mice with liver failure by regulating the IL-6/STAT3 signaling pathway. Accordingly, daucosterol combined with UCMSC-derived exosomes may be a prospective treatment strategy for liver failure.

Tang H, Xiong Q, Yin M, Feng H, Yao F, Xiao X, Hu F, Liao Y. LncRNA PVT1 delays skin photoaging by sequestering miR-551b-3p to release AQP3 expression via ceRNA mechanism. Apoptosis 2023; 28:912-924. [PMID: 37000315 DOI: 10.1007/s10495-023-01834-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/17/2023] [Indexed: 04/01/2023]
Abstract
Understanding human skin photoaging requires in-depth knowledge of the molecular and functional mechanisms. Human dermal fibroblasts (HDFs) gradually lose their ability to produce collagen and renew intercellular matrix with aging. Therefore, our study aims to reveal the mechanistic actions of a novel ceRNA network in the skin photoaging by regulating HDF activities. Photoaging-related genes were obtained in silico, followed by GO and KEGG enrichment analyses. Differentially expressed lncRNAs and miRNAs were screened from the GEO database to construct the ceRNA co-expression network. In skin photoaging samples, PVT1 and AQP3 were poorly expressed, while miR-551b-3p was highly expressed. The relationships among the lncRNA, miRNA and mRNA were explored through the ENCORI database and dual luciferase reporter assay. Mechanistically, PVT1 could sequester miR-551b-3p to upregulate the expression of AQP3, which further inactivated the ERK/p38 MAPK signaling pathway. HDFs were selected to construct an in vitro cell skin photoaging model, where the senescence, cell cycle distribution and viability of young and senescent HDFs were detected by SA-β-gal staining, flow cytometry and CCK-8 assay. In vitro cell experiments confirmed that overexpression of PVT1 or AQP3 enhanced viability of young and senescent HDFs and inhibited HDF senescence, while miR-551b-3p upregulation counteracted the effect of PVT1. In conclusion, PVT1-driven suppression of miR-551b-3p induces AQP3 expression to inactivate the ERK/p38 MAPK signaling pathway, thereby inhibiting HDF senescence and ultimately delaying the skin photoaging.

Abstract
The complexity of central nervous system diseases together with their intricate pathogenesis complicate the establishment of effective treatment strategies. Presently, the superiority of adipose-derived mesenchymal stem cells (ADSCs) on neuronal injuries has attracted significant attention. Similarly, extracellular vesicles (EVs) are potential interventional agents that could identify and treat nerve injuries. Herein, we reviewed the potential effects of ADSCs and EVs on amyotrophic lateral sclerosis (ALS) injured nerves, and expound on their practical application in the clinic setting. This article predominantly focused on the therapeutic role of ADSCs concerning the pathogenesis of ALS, the protective and reparative effects of EVs on nerve injury, as well as the impact following the combined usage of ADSCs and EVs in ALS.
