The pan-PPAR agonist lanifibranor reduces portal pressure independent of fibrosis reduction through the splanchnic vasculature.

Portal hypertension (PH) can cause severe complications in patients with advanced chronic liver disease (aCLD). The pan-peroxisome proliferator-activated receptor (pan-PPAR) agonist lanifibranor reduces portal pressure in preclinical models of aCLD. Since the effect on PH might be secondary to fibrosis improvement, we investigated the effect of lanifibranor on PH, hepatic and splanchnic angiogenesis in mouse models of fibrotic and prehepatic non-fibrotic PH.

Generation of post-surgical minimal residual disease models to investigate metastasis in soft tissue sarcoma patient-derived orthotopic xenografts.

Despite optimal multimodal treatment including surgical resection, 50%-80% of high-grade soft tissue sarcoma (STS) patients metastasize. Here, we present a protocol for the generation and use of post-surgical minimal residual disease models to investigate metastatic relapse in STS patient-derived xenografts. We describe steps for orthotopic engraftment of high-grade STS patient-derived tumor tissue.

STE20 kinase TAOK3 regulates type 2 immunity and metabolism in obesity.

Healthy adipose tissue (AT) contains ST2+ Tregs, ILC2s, and alternatively activated macrophages that are lost in mice or humans on high caloric diet. Understanding how this form of type 2 immunity is regulated could improve treatment of obesity. The STE20 kinase Thousand And One amino acid Kinase-3 (TAOK3) has been linked to obesity in mice and humans, but its precise function is unknown.

Direct co-registration of [F]FDG uptake and histopathology in surgically excised malignancies of the head and neck: a feasibility study.

Purpose: Recent technical advancements in PET imaging have improved sensitivity and spatial resolution. Consequently, clinical nuclear medicine will be confronted with PET images on a previously unfamiliar resolution. To better understand [F]FDG distribution at submillimetric scale, a direct correlation of radionuclide-imaging and histopathology is required.
