siRNA Efficacy in a Xenograft Tumor Model
Protein kinase N3 (PKN3) is a serine/threonine kinase implicated in tumor progression across multiple cancer types. PKN3 mRNA is almost undetectable in normal adult tissues but is upregulated in various cancer cells, indicating that siRNA may be a promising approach to inhibit tumor growth by reducing the expression of PKN3. WuXi AppTec scientists established different siPKN3 molecules and evaluated …Read More >
Paclitaxel-Resistant Tumor Models
Despite the excellent clinical response to paclitaxel therapy, drug resistance inevitably develops in subsequent treatments. The mechanisms for resistance to paclitaxel include drug efflux transporter overexpression, altered apoptotic gene expression, and changes associated with microtubules to reduce the influence of this chemotherapeutic agent. The development of targeted therapies for overcoming paclitaxel resistance represents an unmet medical …Read More >
NK Cell Humanized Tumor Models
NK cells are effector innate lymphoid cells (ILCs) that do not require antigen-specific priming. NK cells are not only killer cells that help to suppress tumors, but also are involved in the generation and maintenance of adaptive immune responses. The process of antibody-dependent cell-mediated cytotoxicity (ADCC) makes use of innate immune cells which provide antitumor …Read More >
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 >
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 >

T-DXd Resistant Tumor Models with ABCG2
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. One mechanism of resistance involves efflux of the ADC payload by the transporter …Read More >
