Basal-like tumors are clinically aggressive and lack targeted therapies because they are estrogen receptor (ER)-negative and HER2-negative. Dr. Cryns and colleagues have shown that a cell stress protein called αB-crystallin contributes to the aggressive behavior of basal-like tumors. More recently, they have developed new in vivo models of basal-like breast cancer that spread (“metastasize”) from the breast to the brain and other organs. Using these in vivo models, the researchers have demonstrated that αB-crystallin is a key regulator of breast cancer metastasis. In 2012-2013, they created a new genetic model of breast cancer and demonstrated that deleting the αB-crystallin gene inhibits lung metastasis. The team has also demonstrated that reducing the expression of αB-crystallin may make cancer cells more sensitive to chemotherapy and some targeted therapies. Finally, they have identified proteins that interact with αB-crystallin and are determining the potential role of these proteins in metastasis. These studies provide novel insights into the molecular mechanisms of basal-like breast cancer and point to αB-crystallin as a promising drug target in these poor-prognosis breast tumors.

In addition, he serves as a consultant to the Oncology Drug Advisory Committee of the FDA, serves on several study sections nationally and internationally including: NIH, Komen Foundation, Avon Foundation, American Cancer Society. Alberta Cancer Board and the Imperial Cancer Fund. He is a member of editorial boards and reviewer for numerous journals, including Journal of the National Cancer Institute, Journal of Clinical Oncology, and Clinical Cancer Research. He has published extensively in the area of breast cancer therapeutics, with a focus on new endocrine therapy, chemotherapy and novel targeted therapies.
Dr. Gradishar received his medical degree form the University of Illinois Abraham School of Medicine in Chicago. He completed a residency and chief residency in internal medicine at Michael Reese Hospital and Medical Center in Chicago and a fellowship in medical oncology at the University of Chicago.
