Systematic prioritization of candidate genes in camptothecin biosynthesis using multi‐omics and deep learning

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Camptothecin (CPT), a plant‐derived monoterpene indole alkaloid first identified in Camptotheca acuminata, is a drug precursor widely used for cancer chemotherapeutics. However, the full set of genes responsible for CPT biosynthesis remains unclear, hindering efforts to elucidate the complete pathway or establish biosynthetic production of CPT

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, Volume 20, Issue 8, Page 2114-2128, August 2026.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, Volume 6, Issue 8, August 2026.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Antibody–Drug Conjugates and Peptide–Drug Conjugates: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 8, August 2026.
The graphic summarizes the design principles, intracellular trafficking, clinical progress, challenges, and future directions of antibody–drug conjugates (ADCs) and peptide–drug conjugates (PDCs). ADCs consist of a tumor‐targeting antibody, a chemical linker, and a potent payload, whereas PDCs use peptide ligands to deliver cytotoxic, radionuclide, or ...

Delivery of nano‐formulated drugs to solid tumours is selectively increased by co‐application of the vascular disrupting agent CA4P

British Journal of Pharmacology, Volume 183, Issue 16, Page 4663-4674, August 2026.
Background and purpose Nano‐formulated chemotherapeutics prolong systemic availability of drugs and can reduce systemic toxicity, but their accumulation in solid tumours is often limited and unpredictable. Broadly applicable strategies to selectively enhance tumour delivery are lacking.

Screening for cold tolerance genes in C. elegans, whose expressions are affected by anticancer drugs camptothecin and leptomycin B

Scientific Reports
Temperature is a vital environmental factor affecting organisms’ survival as they determine the mechanisms to tolerate rapid temperature changes. We demonstrate an experimental system for screening chemicals that affect cold tolerance in Caenorhabditis ...

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, Volume 24, Issue 8, Page 4823-4843, August 2026.
ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

In Silico Study of Camptothecin-Based Pro-Drugs Binding to Human Carboxylesterase 2

Biomolecules
Pro-drugs, which ideally release their active compound only at the site of action, i.e., in a cancer cell, are a promising approach towards an increased specificity and hence reduced side effects in chemotherapy.
