Abstract
Liver regeneration (LR) is a complex process encompassing three distinct phases: priming, proliferation phase and restoration, all influenced by various regulatory factors. After liver damage or partial resection, the liver tissue demonstrates remarkable restorative capacity, driven by cellular proliferation and repair mechanisms. The essential roles of non-coding RNAs (ncRNAs), predominantly microRNAs (miRNAs), long non-coding RNAs (lncRNAs) and circular RNA (circRNA), in regulating LR have been vastly studied. Additionally, the impact of ncRNAs on LR and their abnormal expression profiles during this process have been extensively documented. Mechanistic investigations have revealed that ncRNAs interact with genes involved in proliferation to regulate hepatocyte proliferation, apoptosis and differentiation, along with liver progenitor cell proliferation and migration. Given the significant role of ncRNAs in LR, an in-depth exploration of their involvement in the liver's self-repair capacity can reveal promising therapeutic strategies for LR and liver-related diseases. Moreover, understanding the unique regenerative potential of the adult liver and the mechanisms and regulatory factors of ncRNAs in LR are crucial for improving current treatment strategies and exploring new therapeutic approaches for various liver-related diseases. This review provides a brief overview of the LR process and the ncRNA expression profiles during this process. Furthermore, we also elaborate on the specific molecular mechanisms through which multiple key ncRNAs regulate the LR process. Finally, based on the expression characteristics of ncRNAs and their interactions with proliferation-associated genes, we explore their potential clinical application, such as developing predictive indicators reflecting liver regenerative activity and manipulating LR processes for therapeutic purposes.

Su F, Huo D, Yang H, Sun L. CircRNA8388 functions as the sponge for miR-2392 during intestinal regeneration in sea cucumber Apostichopus japonicus. Int J Biol Macromol 2024; 274:133302.

Abstract
The sea cucumber Apostichopus japonicus can expel internal organs under stress and regenerate them subsequently. However, growth is delayed during regeneration, significantly impacting the industry. Circular RNAs (circRNAs) are single-stranded circular RNA molecules produced through alternative splicing of mRNA precursors. They play crucial roles in regulating gene expression via the ceRNA mechanism. In this study, circRNA profiles of control and regenerated intestines were constructed. A total of 15,874 circRNAs were identified, with a length of 300-350 nucleotides (nt) being the most abundant. Sanger sequencing confirmed the circular structure of circRNA398. Compared with the normal intestine, 50 and 83 differentially expressed circRNAs (DE-circRNAs) were identified in the regenerated intestine at 1 and 3 days post evisceration (dpe), respectively. Gene ontology (GO) terms for signal transduction and development regulation were most significantly enriched in 1dpeVScon and 3dpeVScon treatments, respectively. The dual-luciferase assay revealed that circRNA8388 functions as a sponge for miR-2392, participating in the remodeling of the extracellular matrix (ECM). In conclusion, these findings will contribute to the enhancement of the non-coding RNA database for echinoderms and lay the groundwork for future investigations into circRNA regulation during intestinal regeneration.

A new cell-free therapeutic strategy for liver regeneration: Human placental mesenchymal stem cell-derived extracellular vesicles. J Tissue Eng 2022; 13:20417314221132093. [PMID: 36313857 PMCID: PMC9597011 DOI: 10.1177/20417314221132093] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Accepted: 09/26/2022] [Indexed: 11/06/2022] Open
Abstract
Mesenchymal stem cells (MSCs) have potential role in organ regeneration therapy. Previous work indicating that MSCs confer protection against liver disease. Here, we aimed to determine the potential application in liver regeneration of human placenta-derived MSCs extracellular vesicles (hPMSCs-EVs) via experimental hepatectomy. hPMSCs-EVs were administered intravenously 24 h before 70% partial hepatectomy, the specific composition of hPMSCs-EVs was identified by sequencing and validated by the quantitative polymerase chain reaction, including circ-RBM23. The role of circ-RBM23 in L02 cell was evaluated and it was found that circ-RBM23 knockdown inhibited L02 cell proliferation both in vitro and in vivo. The competing endogenous RNA function of circ-RBM23 was evaluated by the RNA immunoprecipitation assay and found that circ-RBM23 shares miRNA response elements with RRM2. Overexpressed circ-RBM23 bound competitively to miR-139-5p, preventing the miRNA-mediated degradation of RRM2, activating the expression of eIF4G and AKT/mTOR, and facilitating liver regeneration. These results indicate that hPMSCs-EVs prevent hepatic dysfunction and improve liver regeneration in vivo and hepatocytes proliferation in vitro, potentially via circ-RBM23 delivery.
