Abstract

Duvelisib (DVB), a selective PI3K‐δ/γ inhibitor approved for chronic lymphocytic leukemia, requires detailed metabolic characterization to support early drug development and selection of appropriate toxicology species. Because drug metabolism varies across species, an integrated system such as primary hepatocytes containing both Phase I and Phase II enzymes is critical for accurately defining metabolic pathways and identifying potential reactive metabolites.

Genetic evidence and multi-omics characterization of DEHP-relevant detoxification and metabolic heterogeneity in hepatocellular carcinoma

Human evidence linking di(2-ethylhexyl) phthalate (DEHP) exposure to hepatocellular carcinoma (HCC) is limited, and it remains unclear whether DEHP-relevant detoxification biology captures clinically meaningful HCC heterogeneity. We integrated two-sample Mendelian randomization, proteomic and phosphoproteomi...

Integrating in vivo metabolism, pharmacokinetics, and dual-indicator scoring for PK-marker selection of Celosiae Semen saponins.

The total saponins from Celosiae Semen (TSCS) show hepatoprotective and lipid-lowering effects against metabolic dysfunction-associated steatotic liver disease (MASLD). However, their in vivo metabolic fate and holistic pharmacokinetic (PK) features remain largely uncharacterized. In this study, an integrated PK-marker...

Integrated cell-mouse metabolomics reveals toxicity mechanisms and biomarkers of prothioconazole exposure.

BACKGROUND Prothioconazole (PTC) is one of the most widely used triazole fungicides worldwide, while its major metabolite, prothioconazole-desthio (dPTC), exhibits enhanced toxicological potential. However, the metabolic perturbations induced by chronic PTC exposure and sensitive biomarkers for exposure monitoring rema...

Integrative multi-omics profiling reveals an association between lipid metabolism dysregulation and bortezomib-induced cerebral hemorrhage in zebrafish

Bortezomib (BTZ), a first-generation proteasome inhibitor, serves as a cornerstone chemotherapeutic agent for Multiple Myeloma (MM), with its clinical application in oncology expanding rapidly in recent years. Using vascular-specific transgenic zebrafish models, we systematically evaluated BTZ-induced toxicity at 4–5 m...

Untargeted LC-MS Metabolomics Reveals Source-Dependent Metabolic Remodeling of Caco-2 Cells Exposed to Bovine Hydatid Cyst Fluid.

Hydatid cyst fluid (HCF) is a biochemically complex parasite-derived mixture whose effects on host and cancer cells are highly context dependent. The aim of this study was to determine whether short-term exposure to bovine liver- or lung-derived HCF alters Caco-2 XTT-based viability/metabolic activity and to characteri...
