Mark Jackson graduated from Kent State University in 1996, and then joined the Biomedical Sciences Training Program at Wright State University. While there, he studied the regulation of p53 by Hdm2 and HdmX, obtaining his Ph.D. in Biochemistry and Molecular Biology in 2001. After completing his Ph.D., Dr. Jackson joined the lab of Dr. George Stark in the Molecular Genetics Department at the Cleveland Clinic, where he continued his studies of the p53 tumor suppressor. He also developed in vitro transformation models and forward genetic technologies that are currently used in his own lab to decipher the genetics of breast hyperplasia. Dr. Jackson joined the Department of Pathology and the Case Comprehensive Cancer Center in the fall of 2007.

The Jackson laboratory focuses on genetic events that contribute to breast hyperplasia. We have developed a breast cancer model that starts with normal human mammary epithelial cells (HMECs), and utilizes four genetic alterations associated with breast cancer, including inactivation of two tumor suppressors, p16INK4a and p53, and elevated expression of MYC and oncogenic HER2 or RAS. The resulting cells grow anchorage-independently, and possess hallmarks associated with cancer cells. Using this model we can interrogate the contribution of breast specific tumor-suppressive signaling and define how oncogene activation dismantles these suppressive signals to drive transformation and cancer progression. Current areas of focus include paracrine/autocrine TGF-beta, Oncostatin M, and Interferon signaling.

To identify novel proteins that can substitute for each of the known elements in HMEC transformation, we have developed a set of insertional mutagenesis lentiviral vectors (VBIM, validation-based insertional mutagenesis). Using the VBIM viruses we perform forward genetic screens to identify novel genetic alterations that can replace one of the four alterations that drive transformation in our model. By merging a powerful breast cancer model with an emerging technology we seek to identify signaling changes that occur during breast hyperplasia. We recently identified FAM83B (Family with Sequence Similarity 83, member B) based on its ability to substitute for RAS in the transformation of human mammary epithelial cells (HMECs). Interestingly, FAM83B is one of eight members of a protein family (FAM83) characterized by a highly conserved domain of unknown function (DUF1669), which is sufficient for HMEC transformation. FAM83B co-precipitates with CRAF, increasing CRAF membrane localization, and elevating MAPK, mTOR, and PLD signaling. Together these results suggest that FAM83 members constitute a novel oncogene family that provides vital new targets for therapeutic intervention that may significantly impact an oncologist's ability to treat cancer.
