Research Abstract

Defect of vesicle transport related molecule Hrs diminishes the expression of c-Myc. There are some reports concerning the relationship between c-Myc overexpression and poor prognosis of cancer patients. We attempted to identify new therapeutic target utilizing c-Myc overexpression as a biomarker. We used a siRNA library consists of 3500 druggable genome for a screening, and selected Casein Kinase 1 epsilon as a new target. We also showed IC261, a specific inhibitor of Casein Kinase 1 epsilon has therapeutic effects in mouse ovarian cancer model.
