Phosphatase of regenerating liver-1 (PRL-1) controls various cellular processes and liver regeneration. However, the roles of PRL-1 in liver regeneration induced by chorionic-plate-derived mesenchymal stem cells (CP-MSCs) transplantation remain unknown. Here, we found that increased PRL-1 expression by CP-MSC transplantation enhanced liver regeneration in a bile duct ligation (BDL) rat model by promoting the migration and proliferation of hepatocytes. Engrafted CP-MSCs promoted liver function via enhanced hepatocyte proliferation through increased PRL-1 expression in vivo and in vitro. Moreover, higher increased expression of PRL-1 regulated CP-MSC migration into BDL-injured rat liver through enhancement of migration-related signals by increasing Rho family proteins. The dual effects of PRL-1 on proliferation of hepatocytes and migration of CP-MSCs were substantially reduced when PRL-1 was silenced with siRNA-PRL-1 treatment. These findings suggest that PRL-1 may serve as a multifunctional enhancer for therapeutic applications of CP-MSC transplantation.

An optimal administration approach is critical for effective mRNA delivery and treatment. Nebulizer inhalation offers a mild, convenient, and noninvasive strategy with high translational potential but primarily focused on lung delivery. In this study, we found that surface charges influence tissue targeting of mRNA lipid nanoparticle (mRNA-LNP) postnebulization.

Abnormal accumulation of TAR DNA-binding protein-43 (TDP-43) is a hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Small interfering RNAs (siRNAs) targeting TDP-43 offer potential therapeutic strategies for these diseases. However, efficient and safe delivery of siRNAs to the central nervous system (CNS) remains a critical challenge.

Aldehyde dehydrogenase 2 (ALDH2) is a critical enzyme involved in the detoxification of acetaldehyde. Although numerous studies have demonstrated the significance of ALDH2 in alcohol-associated liver disease (ALD), its role in alcohol-induced activation of liver progenitor cells (LPCs) has not been thoroughly investigated. Proteomic analysis of serum samples from patients with either normal ALDH2 genotype or ALDH2 mutation following alcohol consumption revealed that ALDH2 deficiency may suppress LPC proliferation.

Introduction: Accurate liver volumetry is crucial for hepatectomy. In this study, we developed and validated a deep learning system for automated liver volumetry in patients undergoing hepatectomy, both preoperatively and at 7 days and 3 months postoperatively.
Methods: A 3D U-Net model was trained on CT images from three time points using a five-fold cross-validation approach.
