The dynamic adhesion of cells to their surrounding extracellular matrix provides many of the environmental cues necessary for controlling cell migration and cell shape, survival, proliferation and differentiation. These fundamental events regulate an organism’s normal development, maintenance and recovery from injury and infection. Defects in the signaling pathways associated with cell adhesion provide the basis for cell transformation and cancer cell metastasis, various developmental defects and cardiovascular disease.
My lab uses a multi-faceted approach combining biochemistry, cell and molecular biology and various high-end microscopy techniques along with mouse tumor models to determine the molecular organization of the proteins that are involved in cell adhesion and thereby understand how they each contribute to cell behavior in vivo. We are particularly interested in characterizing the function of the molecular scaffold/adapter proteins Paxillin and Hic-5 during tumor cell migration and invasion. We have found that these multi-domain proteins bind numerous structural and signaling proteins including kinases, phosphatases and Rho family GTPase regulators and effectors. We hypothesize that it is through these various interactions that the cell coordinates intracellular signaling and cytoskeletal reorganization to regulate cell adhesion, migration and tumor invasion.

Dr. Dennis Stelzner has been elected a Fellow in the American Association of Anatomists. He was presented with a citation and plaque at the annual meeting of the American Association of Anatomists during the FASEB meeting on April 12, 2011 in Washington, DC.
The citation reads:
Spinal cord injury (SCI) has been studied during his entire career using neuroanatomical and ultrastructural methods. He showed that the ability of nerve tracts to regenerate or grow around partial SCI during development is dependent on their maturation at the time of injury.
Differences were also found in the ability of frog optic and tectal efferent axons to regenerate through the same diencephalic injury. The intrinsic cellular response needed for CNS axons to regenerate is the focus of his present work on propriospinal neurons using "molecular neuroanatomy" to determine factors underlying a maximal regenerative response after spinal cord injury.
