Antibody-drug conjugates (ADCs), exemplified by HER2-targeted Enhertu and TROP2-targeted Trodelvy, have demonstrated significant therapeutic potential in cancers. However, a subset of patients remains refractory to ADC treatment.  WuXi AppTec contributed to a research article which demonstrated that excessive cancer-associated fibroblasts (CAFs) can form a fibrotic barrier within a tumor microenvironment, impeding the tissue uptake of …Read More >

Antibody-drug conjugates (ADCs) hold great promise as targeted cancer therapeutics, but their complex structure poses significant development and safety challenges for project teams.  In our latest webinar, experts discuss methodologies for evaluating ADC efficacy, resistance, and immunogenicity that address both antibody-specific and payload-specific mechanisms through various multi-dimensional assays. This webinar offers a comprehensive perspective on …Read More >

BRCA1 and BRCA2 proteins are key components of the homologous recombination repair pathway for repairing double-stranded DNA breaks.  Mutations in BRCA genes can significantly increase the risk of certain cancers such as breast, ovarian, pancreatic, and prostate cancer. To mimic the effects of BRCA2 deficiency in humans, WuXi Biology has constructed a BRCA2 deficient mouse …Read More >

Bromodomain and extra-terminal domain (BET) family proteins are key regulators of gene transcription and have been implicated in a wide range of diseases, making these proteins a potential therapeutic target.  Abnormal BET protein activity has been linked to cancer, inflammatory disorders, viral infections, and neurodegenerative conditions. In a recent publication, researchers highlight the discovery of …Read More >

Cyclin-dependent kinases (CDKs) and their cyclin regulatory subunits form complexes that are essential for driving abnormal growth processes in cancer cells, making these proteins important targets for cancer treatment. To support the discovery of novel CDK inhibitors, the WuXi AppTec Discovery Biology Structural Biology platform provides a wide range of biophysical, X-ray crystallography, and cryo-EM …Read More >

Signal transducer and activator of transcription (STAT) proteins are key mediators of cellular immunity, proliferation, apoptosis, and differentiation. STATs are known to play a key role in the pathogenesis of many different diseases (including cancer) and the development of drugs directly or indirectly targeting STAT signaling is a major focus for researchers. The WuXi AppTec …Read More >

At the 2024 Protein & Antibody Engineering Summit (PEGS) Europe, Crelux presented a poster highlighting its drug discovery platform for the production and characterization of protein biologics and their antigens. This platform combines construct and expression scouting, customizable high-throughput protein purification, and affinity/kinetics determination using various biophysical techniques, as well as paratope and epitope mapping …Read More >

Tuberculosis is the leading cause of death from an infectious disease and is caused by Mycobacterium tuberculosis (MTB). Inosine-5′-monophosphate dehydrogenase (GuaB) is an enzyme that performs the rate-limiting step in the de novo biosynthesis of guanine, which is critical for growth of bacteria, including MTB. The development of a novel antibiotic that inhibits GuaB could …Read More >
