In this month’s newsletter, learn more about our comprehensive panel of CDK4/6 inhibitor-resistant breast cancer models and in vitro imaging assays for compound profiling.  We also showcase our recent publications describing the development of HBV antigen inhibitors and noncovalent inhibitors of the SARS-CoV-2 3C-like protease (3CLpro).  

Discover our comprehensive platform of CDX and PDX tumor models, carrying BRAF mutations across multiple cancer types: 18 CDX models carrying BRAF mutation (V600E, G469A, G464V, G466V, G596R or N581Y), covering melanoma, breast cancer, lung cancer and colorectal cancer 18 PDX models carrying BRAF mutation (V600E, G469A, G469E, D594N or N581S), covering melanoma, pancreatic cancer, …Read More >

Leverage our extensive panel of rat xenograft and syngeneic tumor models. Advantages for using rats in preclinical efficacy studies compared with mice include: more similar metabolism and physiology to human; easier use for orthotopic model surgery, vascular manipulation, and imaging; larger sampling sizes to ensure sufficient amount for bioanalysis; consistent animal species to toxicology studies …Read More >

Delivery carriers are a critical component in the development of mRNA vaccines. Here, we describe the synthesis of a cationic polymer as a carrier for mRNA cancer vaccine delivery. In vivo results show that this polymer-based mRNA vaccine significantly delays tumor growth after vaccination of mice. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9743697/  

KRAS mutant proteins that drive cancer development are highly similar in sequence and structure. Direct inhibitors are most likely to bind to the catalytic domain of KRAS. However, recent studies have found that KRAS mutants can also be targeted by heterogeneous sites, to develop covalent inhibitors of KRAS mutants. The discovery of inhibitors that selectively …Read More >

Leverage our extensive panel of CDK4/6 inhibitor resistant breast cancer models, including:  In vitro induced Palbociclib resistant MCF-7 cell line In vivo induced Palbociclib resistant MCF-7 model In vivo induced Abemaciclib resistant MCF-7 model In vivo induced Ribociclib resistant MCF-7 model View additional drug-resistant models in our platform

In this week’s installment of our “How Does It Work?” video series, we explore Antibody Drug Conjugates. Monoclonal antibodies are highly versatile molecules that we can modify to generate new and improved cancer therapies. Here we have a type of modified antibody, known as an antibody drug conjugate, or ADC. The ADC contains two antigen …Read More >
