Preclinical platform for nucleic acid drug evaluation: siRNA and mRNA therapeutics
SITC Poster #59: Since the emergence of the COVID-19 pandemic, numerous nucleic-acid therapeutics have been approved for clinical use. Distinguished from conventional protein-targeted therapy, nucleic acid therapeutics offer the potential for sustained effects via gene modification or inhibition. In this study, we conducted a comprehensive evaluation of the activity and anti-tumor effects of PKN3-targeted siRNA …Read More >
Colitis-Associated Cancer Mouse Model
The cumulative impact of chronic inflammation in patients with inflammatory bowel disease (IBD) predisposes them to the development of IBD-associated colorectal cancer. To support drug discovery research in this area, WuXi AppTec has developed a colitis-associated cancer mouse model to reflect the human colon’s carcinogenesis pattern derived from inflammation. Key features of this model include …Read More >
Combined Inhibition of KRAS G12C and PD1 Boosts Therapeutic Efficacy via Conditioning of Tumor Microenvironment
SITC Poster #466: Mutant KRAS is linked to PD-L1 expression, and oncogenic RAS signaling promotes an immunosuppressive tumor microenvironment by upregulating PD-L1 expression. Consequently, combining KRAS G12C inhibitors with immune checkpoint blockers shows promising benefits. To better understand the mechanisms underlying the combined inhibition of KRAS G12C inhibitor AMG 510, and anti-PD-1 antibody nivolumab, LU-01-0361 …Read More >
Discovery and Characterization of ZL-2201, a Potent, Highly Selective, and Orally Bioavailable Small-molecule DNA-PK Inhibitor
DNA-dependent protein kinase (DNA-PK) plays an important role in the overall survival and proliferation of cells, making this enzyme an intriguing target for the treatment of a variety of cancers. In our latest publication, WuXi AppTec scientists contributed to the discovery and characterization of ZL-2201, a potent and highly selective small molecule DNA-PK inhibitor. In …Read More >
Osimertinib-Resistant Cell Lines and Models
Despite the robust clinical activity exerted by osimertinib, a majority of patients eventually exhibit disease progression while receiving this drug. Resistance to osimertinib includes both on-target and off-target mechanisms. With the use of osimertinib for advanced EGFR-mutant NSCLC increasing, the development of targeted therapies toward osimertinib resistance represents an unmet medical need. To support research …Read More >
Enhertu-Induced Resistant Tumor Models
Antibody‒drug conjugates (ADCs), which combine the advantages of monoclonal antibodies with precise targeting and payloads, show great potential as cancer therapies. However, primary and secondary resistance is frequently observed, and development of next generation ADCs necessitates the establishment of resistant tumor models. WuXi AppTec offers validated, Enhertu-induced resistant tumor models to support project teams focused …Read More >
OncoWuXi Express: In vitro and in vivo evaluation of an mRNA-encoded bispecific antibody (EpCAM/CD3)
Introduction: Nucleic acid therapies can regulate the expression level or activity of disease-related targets at the genetic level, offering advantages such as a wide target range, programmability, and rapid iteration. However, the wide application of nucleic acid drugs still faces many challenges, including delivery efficiency and off-target effects. To address these challenges, the Oncology-Immunology team …Read More >
Metastasis-Related In Vitro Assays and Xenograft Models
Cell migration, invasion, and adhesion are pivotal steps in cancer metastasis. To support research in this field, WuXi AppTec offers in vitro transwell migration and invasion assays using multiple cell types for assessing cell migratory behavior. In addition, our in vivo metastasis panel includes a broad range of brain, bone, and liver xenograft models covering …Read More >
Oncolytic Virus Platform
Oncolytic viruses (OVs) are emerging as a promising therapeutic approach for treating cancer. OVs are capable of both tumor-specific cell lysis and immune stimulation and can be optimized for enhanced tumor selectivity. WuXi AppTec offers a comprehensive platform of OV-related services, including virus engineering and validation, immune profiling and lysis assays, tumor cell selectivity assays, …Read More >
