Orthotopic and Metastasis Tumor Models in Rats
Rat tumor models are a better mimic of human pathology compared to mice. The tumor stroma component of rats is about 1.5 to 2-fold higher relative to mice. Rats are considered an ideal model for preclinical efficacy studies, as they are physiologically, metabolically, and genetically more similar to humans. To support drug discovery teams, WuXi …Read More >
Syngeneic Tumor Models with Resistance Mechanisms to PD-1 Blockade
PD-1 blockade has demonstrated remarkable clinical efficacy across various tumor types. However, primary or acquired resistance eventually leads to cancer progression in clinical settings. Understanding the underlying mechanisms of resistance is both necessary and urgent to enhance clinical outcomes. At AACR 2024, WuXi AppTec presented a poster describing the development of two types of anti-PD-1 …Read More >
Armoring CAR-T Therapy with PD-1 Blockade
The efficacy of CAR-T therapy is substantially influenced by the tumor microenvironment. This is particularly evident when PD-L1 is activated through CAR-T, leading to the inhibition of CAR-T cell activity via the PD-1 pathway. At AACR 2024, WuXi AppTec presented a poster describing an engineered CAR-T therapy that targets mesothelin and concurrently expresses a membrane-bound …Read More >
Heme Oxygenase-1-Targeting Molecules
WuXi AppTec scientists published a study in the open access archive ChemRxiv describing the discovery of highly selective, novel, heme oxygenase-1 (HO-1) targeting molecules. HO-1, primarily a heme-degrading enzyme, has been identified as a potential therapeutic target in diseases such as cancer and neurodegenerative disorders. Here, we report the discovery of five series of novel …Read More >
DEL-Generated Endocytosis Receptor-Binding Peptides for Oligonucleotide Delivery
Despite the success of delivery technologies such as lipid nanoparticles and trivalent GalNAc conjugation, targeted delivery of oligonucleotides to extra hepatic tissues remains a challenge. At this year’s OPT Congress, WuXi AppTec presented a poster showing the utilization of our peptide-based DNA-encoded library screening platform to identify endocytosis receptor-binding peptides. The binding affinity of hit …Read More >

PROTAC Optimization Strategies
What if a constructed PROTAC with a confirmed high-affinity warhead doesn’t work as expected? That means we need to take a closer, more careful look at how it’s designed and how it works. In this video, our expert from WuXi Biology shares strategies to address such an R&D scenario.
