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 >
Upregulation of drug metabolism enzymes mediates ADC resistance in a HER2-positive cancer cell line
SITC Poster #1162: Enhertu is currently approved for the treatment of patients with HER2-positive breast cancer, gastric cancer, or HER2-mutant non-small cell lung cancer. However, despite Enhertu’s clinical benefits, most patients inevitably experience disease progression and mortality. Understanding drug resistance mechanisms can aid in developing new treatment strategies for drug-resistant clinical patients. In this study, …Read More >
OncoWuXi Express: In Vitro Hydrogel-based 3D Tumor Models
Introduction: Over the last few years, the clinical success of immune checkpoint inhibitors has increasingly drawn attention to cancer therapies that target the tumor microenvironment (TME). TME consists of various cell types that are embedded in the extracellular matrix (ECM), including immune cells, endothelial cells, and cancer associated fibroblasts, all of which play critical roles …Read More >
Discovery and Characterization of ZL-2201, a Potent, Highly Selective, and Orally Bioavailable Small-molecule DNA-PK Inhibitor
