Long-term outcome and risk stratification in compensated advanced chronic liver disease after HCV-cure.
Hepatology
February 2025
Department of Medicine III, Division of Gastroenterology and Hepatology, Medical University of Vienna, Vienna, Austria.
Background And Aims: Around 750,000 patients per year will be cured of HCV infection until 2030. Those with compensated advanced chronic liver disease remain at risk for hepatic decompensation and de novo HCC. Algorithms have been developed to stratify risk early after cure; however, data on long-term outcomes and the prognostic utility of these risk stratification algorithms at later time points are lacking.

Single-cell RNA sequencing (scRNA-seq) enables detailed characterization of cell states but often lacks insights into tissue clonal structures. Here, we present a protocol to probe cell states and clonal information simultaneously by enriching mitochondrial DNA (mtDNA) variants from 3'-barcoded full-length cDNA. We describe steps for input library preparation, mtDNA enrichment, PCR product cleanup, and paired-end sequencing.

Department of Molecular and Cellular Medicine, Institute of Medical Science, Tokyo Medical University, Tokyo, Japan. Electronic address:
Extracellular vesicles (EVs) play a key role in cancer development and cellular homeostasis by transferring the biological cargo to recipient cells. Here, we describe steps for screening EV secretion-related genes by combining a microRNA (miRNA) library and ExoScreen, a highly sensitive EV detection technique. We also detail procedures for screening the direct target genes regulated by miRNAs.

Department of Microbiology, Tumor and Cell Biology, Division of Virology and Immunology, Karolinska Institutet, 171 65 Solna, Sweden. Electronic address:
Protective antibodies against HIV-1 require unusually high levels of somatic mutations introduced in germinal centers (GCs). To achieve this, a sequential vaccination approach was proposed. Using HIV-1 antibody knockin mice with fate-mapping genes, we examined if antigen affinity affects the outcome of B cell recall responses.

Institute for Regenerative Medicine, State Key Laboratory of Cardiology and Medical Innovation Center, Shanghai East Hospital, School of Life Sciences and Technology, Tongji University, Shanghai 200092, China.
Hematopoietic development is tightly regulated by various factors. The role of RNA m6A modification during fetal hematopoiesis, particularly in megakaryopoiesis, remains unclear. Here, we demonstrate that loss of m6A methyltransferase METTL3 induces formation of double-stranded RNAs (dsRNAs) and activates acute inflammation during fetal hematopoiesis.
