Repurposing FDA-approved drugs to inhibit PRL-3, Scientific Reports, 2021

A major goal of our lab’s PRL-3 projects is to find a way to inhibit PRL-3 activity. PRL-3 is essential for the growth and spread of many types of cancer, so if we can find a way to block PRL-3, we could potentially impact many patients. However, the drugs used to target PRL-3 are still…

Methods for high-throughput drug screens of human cancer cells in zebrafish. JoVE, 2020

Meghan and Henry have starred in a JoVE (Journal of Visualized Experiments) video article explaining how the lab transplants human cancer cells into zebrafish and uses them for high-throughput drug screening. The benefit of this xenograft model is that we can rapidly screen though hundreds of compounds in living animals, which allows us to find…

The phosphatase PRL-3 drives ALL progression, Oncogenesis 2020

The lab’s first research manuscript is out! Min’s research defined the oncogenic role of PRL-3 phosphatase in T-cell acute lymphoblastic leukemia (T-ALL), which is a very progressive pediatric cancer and lacks targeted therapies. Our findings show that PRL-3 promotes T-ALL development/onset in zebrafish models and plays a role in engraftment in mouse xenograft models. Cell-culture…
