The EML4-ALK fusion gene occurs in approximately 5% of non-small-cell lung cancers (NSCLCs), making this oncogene an important drug target.  The development of ALK tyrosine kinase inhibitors (ALK-TKIs) has been a major advance in treating NSCLC with this fusion gene, but acquired resistance to ALK-TKIs ultimately limits their use.  To support the development of next-generation …Read More >

High-dimensional (HD) flow cytometry allows researchers to perform deep phenotyping of immune cells at the single cell level with increased accuracy and sensitivity.  This technology enables complex pathway characterization and data integration for the identification of biomarkers used in immunotherapy.  WuXi AppTec offers a comprehensive panel of HD flow cytometry services, with more than 100 …Read More >

The contribution of the X-ray crystallography team from our WuXi AppTec site in Germany was acknowledged in a recent study published in the journal Cancer Discovery. In this study, the authors show that compound STX-478, an allosteric PI3Kα inhibitor, selectively targets prevalent PI3Kα helical- and kinase-domain mutant tumors. STX-478 demonstrated robust efficacy in human tumor …Read More >

OncoWuXi Express will continue to keep you informed about updates to our on-line tumor model database (OncoWuXi Database), as well as our recent progress in cancer and autoimmune research. In this issue, we showcase our FaDu ATM KO tumor model. Introduction: As reported, several physiological processes, such as the production of reactive oxygen species during …Read More >

Due to the special configuration of the DNA encoded library (DEL), each DEL molecule carries a DNA sequence encoding its identity through a bifunctional linker. The linkers that are considered “redundant” and “troublesome” in traditional drug discovery actually offer innate advantages in many application scenarios. In this article, we review how to utilize DNA-encoded libraries …Read More >

To support antitumor efficacy testing and address the challenges of clinical translatability, WuXi AppTec offers extensive panels of immune-avatar humanized mouse models. Our platform includes hPBMC, hHSC, and hNK humanized models with enabling studies from our platform of over 1,700 CDX and PDX models. These well-established models cover multiple cancer types, including breast, lung, liver, …Read More >

Patient-derived xenografts (PDXs) represent a powerful platform for cancer drug screening and biomarker discovery and are considered the gold standard of in vivo models for their proven clinical relevance to human disease. WuXi AppTec offers a comprehensive platform of more than 1,400 well-annotated PDXs across 30 cancer types. We also provide expanded in vitro, ex …Read More >

In the last decade, targeted protein degradation (TPD) technology has become one of the most promising methods to remove specific disease-related proteins using cellular self-destruction mechanisms.  In our latest White Paper, “Emerging Drug Discovery Strategies for Targeted Protein Degradation” we explore how DNA-encoded library (DEL) technology can be used for direct discovery of proteolysis-targeting chimeras …Read More >
