Kinic index: an artificial intelligence-driven predictive model and multitarget drug discovery framework for hepatocellular carcinoma patients. (PubMed, NPJ Precis Oncol)
Importantly, using the GraphBAN deep learning framework and ADMET-AI screening, we prioritized candidate compounds targeting CYP2C9 and G6PD, followed by molecular docking that validated strong binding affinities, suggesting their potential as novel therapeutics. Together, our study demonstrates that KinicI is a powerful AI-enabled platform for prognostic modeling, molecular stratification, and multitarget drug discovery, providing a foundation for precision oncology and resistance-aware treatment strategies in HCC patients.

DNA damage induced by fungicides triadimefon, triadimenol, and their mixture in human lymphocytes: cytogenotoxicity and computational analysis of metabolic pathways. (PubMed, Drug Chem Toxicol)
While they may down-regulate a gene involved with changes in heart rhythm and neurotoxicity (HCN1). In conclusion, our findings reinforced that the triazole fungicides TF and TN, while effective in agriculture, may pose risks to genomic stability in humans, highlighting the importance of biomonitoring studies in exposed populations.

Retrospection of the USFDA-Approved Halogenated Drugs and Their Implication in Medicinal Chemistry and Drug Discovery: A Perspective of Approved Drugs Between 2019 and 2024. (PubMed, Arch Pharm (Weinheim))
CYP3A4 is a major contributor in the metabolism of 6 drugs, followed by CYP3A (3), CYP1A2 (2), CYP3A4/5 (2), and one each by CYP2C9, UGT1A9, CYP2C8, aldehyde oxidase, and other non-CYP enzymes. The present medicinal chemistry perspective is thus expected to be a valuable read for the medicinal and allied sciences community.

Shaping a pro-carcinogenic hepatic microenvironment by TCDD: An integrated approach combining network toxicology, machine learning, molecular docking, molecular dynamics and experimental validation. (PubMed, Ecotoxicol Environ Saf)
Consistently, down-regulation of CYP1A2 and CYP2C9 and up-regulation of HSP90AB1 were shown by immunofluorescence/Western blotting/RT-qPCR, impairing signaling networks and immune homeostasis and ultimately leading to the establishment of hepatotoxicity and carcinogenic microenvironments. Collectively, the TCDD "target binding-pathway dysregulation-immune imbalance-pathological damage" cascade has been systematically delineated, providing novel targets and a theoretical framework for therapeutic intervention against pollutant-associated liver diseases.

Identification and validation of icaritin-associated prognostic genes in hepatocellular carcinoma through network pharmacology, bioinformatics analysis, and cellular experiments. (PubMed, Front Immunol)
In vitro validation confirmed that ICT suppresses HepG2 and Huh7 cells proliferation and migration in a dose-dependent manner, while molecular analyses demonstrated that ICT treatment significantly downregulates CA9, UCK2, and FABP5 expression and simultaneously upregulates CYP2C9, thereby supporting its role in modulating critical oncogenic pathways. Modulation of ICT-targeted genes was found to effectively suppress HCC progression, underscoring their potential value as prognostic biomarkers and ideal therapeutic targets for the treatment of HCC.

Pharmacogenomics of anthracycline-cyclophosphamide-taxane chemotherapy: an influence of CYP polymorphisms and BMI on breast cancer treatment outcomes. (PubMed, Pharmacogenomics)
AA genotype at G681A in low BMI patients showed the poorest chemotherapy response and lowest PFS (HR>1). CYP2C19 variants (AA) may serve as predictive markers for non-responsiveness towards AC-T chemotherapy in low BMI BC patients, highlighting the need for genetic counselling and nutritional support to improve treatment outcomes.

Long-Read Sequencing Enhances Pharmacogenomic Profiling by Resolving Complex Haplotypes, Novel Star Alleles, and Structural Variants. (PubMed, Clin Pharmacol Ther)
These results demonstrate the superiority of long-read sequencing in phasing and resolving complex genomic regions enabling more precise pharmacogenomic profiling. As sequencing costs decline with rapid technological advances, long-read sequencing may become the method of choice in clinical pharmacogenomics, enhancing therapeutic safety and efficacy.
