Research Interests:

Dr. Ju’s research at Stony Brook University School of Medicine focuses on elucidating the mechanism of translational control mediated by non-coding RNAs in cancer and translating the new discovery to clinical cancer diagnosis and therapy.

His group is the first to discover that p53 regulates the expression of certain miRNAs, opening a new frontier in cancer research.

Dr. Ju’s group is actively investigating the mechanism of miRNAs in proliferation, cell cycle control, chemoresistance to fluoropyrimidines and antifolates in tumor stem cells, and epithelial-to-mesenchymal transition. His group is also developing novel approaches to study post-transcriptional control mediated by miRNAs and RNA binding proteins. As for the translational research, they are interested in the investigation of miRNAs as biomarkers in cancer diagnosis and prognosis.
