Bio

Mark joined the Biology Department as Associate Professor Fall Semester 2015. Prior to coming to BSU, he was a Professor in the Biosciences Department at Minnesota State University for 25 years. Mark’s research focuses on the regulation of tumor development and metastasis in non-small cell lung cancer (NSCLC) and ovarian cancer. The Wallert Cancer Research Team currently has projects in four specific areas (see Research Interests below).  Mark is the Northwest Regional Director for the American Society of Biochemistry and Molecular Biology Student Chapters Steering Committee where he has helped organize the Undergraduate Research in the Molecular Sciences annual meeting held in Moorhead, Minnesota for the past 11 years. In 2005, Mark was recognized as the Council for Advancement and Support of Education / Carnegie Foundation for the Advancement of Teaching Minnesota College Professor of the Year.

Research Interests

The Wallert Cancer Research Team investigates the function of a transmembrane, transport protein, the sodium-hydrogen exchanger isoform 1 (NHE1), as a potential therapeutic target for the treatment of invasive and metastatic tumors.  This investigation has four distinct avenues:

  1. The role of Calcineurin B Homologous Protein Isoform 2 (CHP2) in the development and progression of NSCLC. CHP2 is an NHE1 binding partner that is predominantly expressed during cancer development and progression. This project focuses on the characterization of the function of CHP2 in cancer development and identifying a mechanism to block CHP2 binding to NHE1.
  2. The Regulation of NHE1 Function by Phosphorylation. NHE1 has a series of seven amino acid phosphorylation sites on the cytoplasmic regulatory domain of the protein. These phosphorylation events are catalyzed by five different protein kinases activated by distinct signaling pathways. This project focuses on identifying the role of each of these phosphorylation sites in the regulation of cancer progression and development.
  3. The Regulation of Cell Migration and Invasion by the Palmitoylation of NHE1. Palmitoylation is the reversible, covalent addition of a palmitic acid to a protein. When cells migrate NHE1 moves to the leading edge of the cell and coordinates the events that allow the cells to move and invade surrounding tissues, two key attributes of metastasis. This project focuses on the role of palmitoylation in regulating cell migration and invasion.
  4. The role of Lysophosphatidic Acid (LPA) and Urokinase-type Plasminogen Activator (uPA) signaling to NHE1 in the development and progression of ovarian cancer. LPA and uPA signaling enhance ovarian cancer invasion and metastasis especially in hypoxic microenvironments.  This project investigates the role of NHE1 activation by LPA and uPA in this process.
