Professional Interest/Expertise/Specializations:
The interest in our laboratory is pre-clinical drug development. We have two major current areas of focus - cancer and inflammatory diseases. We have partnered with medicinal chemists and biomedical researchers to target molecules involved in inflammation, carcinogenesis, metastasis, angiogenesis, and bone formation. Some specific projects ongoing in our laboratory are: 1) With Dr. Aleem Gangjee at Duquesne University to create dual TKI/cytotoxic anticancer molecules to target triple negative and basal-like breast cancer and together with Dr. Rheal Towner at the Oklahoma Medical Research Foundation to treat aggressive glioma multforme. 2) With Drs. Pui-Kai Li and Chenglong Li at The Ohio State University, Dr. Thomas Sferra in the Department of Pediatrics and Dr. Randle Galucci in the Department of Pharmaceutical Sciences to create novel molecules targeting the IL-6 signaling pathway at both the level of its receptor and at downstream signaling points (STAT3) for the treatment of inflammation bowel disease, colon carcinogenesis, cancer therapy, wound healing and refractory dermatitis. 3) With Dr. Robert Hurst in the Department of Urology to dicover molecules capable of trageting suppressed cancer cells before they reactivate. 4) With Dr. Sukyung Woo in the Department of Pharmaceutical Sciences to determine whether the above molecules have synergistic anticancer effects when added together with conventional agents. 5) With Dr. Tarisai Dandajena in the Department of Cell Biology/Colleges of Dentistry at the OUHSC to find molecules capable of speeding up tooth movement via increased antiogenesis and osteoclastogenesis.
