The importance of preclinical models for cholangiocarcinoma drug discovery.
Expert Opin Drug Discov
January 2025
Center of Physiology, Pathophysiology and Biophysics, Institute of Physiology and Pathophysiology, Paracelsus Medical University, Salzburg, Austria.
Introduction: Biliary tract cancer (BTC) comprises a clinically diverse and genetically heterogeneous group of tumors along the intra- and extrahepatic biliary system (intrahepatic and extrahepatic cholangiocarcinoma) and gallbladder cancer with the common feature of a poor prognosis, despite increasing molecular knowledge of associated genetic aberrations and possible targeted therapies. Therefore, the search for even more precise and individualized therapies is ongoing and preclinical tumor models are central to the development of such new approaches.
Areas Covered: The models described in the current review include simple and advanced in vitro and in vivo models, including cell lines, 2D monolayer, spheroid and organoid cultures, 3D bioprinting, patient-derived xenografts, and more recently, machine-perfusion platform-based models of resected liver specimens.
Exploring the immune resilience of Mediterranean mussels: recent advances and future directions.

University of Trieste, Department of Life Sciences.
The Mediterranean mussel (Mytilus galloprovincialis) is a key species in European aquaculture, known for its economic and societal importance, particularly as a primary source of income for local fisheries in European coastal areas. While historically resilient to the mass mortality events that have affected other bivalve species, M. galloprovincialis may face increasing threats from emerging pathogens, including bacteria, viruses, and eukaryotic parasites.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has imposed substantial challenges on our society due to the COVID-19 pandemic. This virus relies heavily on its surface glycoprotein (S-glycoprotein) to facilitate attachment, fusion, and entry into host cells. While the nucleoprotein (N) in the ribonucleoprotein core binds to the viral RNA genome.

Human leukocyte antigen (HLA)-G is a nonclassical HLA class I molecule that has an immunosuppressive effect mediated by binding to immune inhibitory leukocyte immunoglobulin-like receptors (LILR) B1 and LILRB2. A conventional HLA-G isoform, HLA-G1, forms a heterotrimeric complex composed of a heavy chain (α1-α3 domains), β2-microglobulin (β2m) and a cognate peptide. One of the other isoforms, HLA-G2, lacks a α2 domain or β2m to form a nondisulfide-linked homodimer, and its ectodomain specifically binds to LILRB2 expressed in human monocytes, macrophages, and dendritic cells.

Bazhen Decoction (Eight Treasures Decoction) has demonstrated efficacy in the treatment of colorectal cancer (CRC), yet the active ingredients in it and the mechanisms underlying their anti-cancer properties are not well understood. Through network pharmacology, the effective components of Bazhen Decoction against CRC and their corresponding key genes were delineated. Molecular docking was executed to identify the active component targeting the key gene CXCL8, which led to the discovery of Quercetin.
