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 >

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 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 >

A new wave of drugs that achieves targeted delivery of radioisotopes is rapidly gaining momentum.  As the discovery pipeline widens and new drug approvals increase, the field is expanding and becoming more diverse in the strategies employed to deliver cell-killing radioisotopes. One area that is showing considerable promise is the incorporation of an isotope-chelating moiety …Read More >

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 >

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 >

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 >
