Passive Heymann nephritis, induced by intravenous injection of anti-Fx1A in susceptible rat strains, is a complement-dependent model of glomerular disease that resembles membranous nephropathy in humans.  At IMMUNOLOGY2024, WuXi AppTec presented a poster demonstrating that rapamycin exerts a protective effect against anti-Fx1A-induced passive Heymann nephritis by reducing proteinuria.  The authors show that this antiproteinuric effect …Read More >

Cyclin-dependent kinases (CDKs) and their cyclin regulatory subunits form complexes that are essential for driving abnormal growth processes in cancer cells.  Although CDK4/6 inhibitors have shown promising results in the clinic, acquired resistance to these therapies is frequently observed. The successful development of next generation therapeutics necessitates a better understanding of the mechanisms underlying this …Read More >

Estrogen receptor α (ERα) is considered the main driver in more than 70% of all breast cancers, making this transcription factor an important drug target.  Activating point mutations in the ERα gene, especially Y537S and D538G, have been linked to acquired resistance to endocrine therapies, and there is an urgent need to develop new strategies …Read More >

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 >
