Meet Pierre McCrea, Ph.D.
About Dr. McCrea
Dr. McCrea is a Professor in the Department of Genetics. Current work asks how the shape of neurons is determined, which is key to understanding nervous system development and how it can go wrong in disease. In the context of the neuron as well as other cell types/ tissues, the lab focuses upon the biology of catenin proteins. For this purpose it employs primary cells, cultured cells, and animal systems. Catenins additionally have notable roles in cancer, with prominent examples being beta-catenin, p120-catenin, and delta-catenin. The McCrea laboratory has revealed new catenin complexes and functions, including actions at the cytoskeleton and cell junctions (e.g. via small-GTPases), and functions in the nucleus/ gene control (e.g. Wnt-pathway). The lab’s purpose is to probe how catenins promote normal development, to assist in understanding dementia, aging, mental illness, and cancer. Coexisting with these scientific enterprises, Dr. McCrea is active in promoting graduate and postdoctoral training and mentorship.

Background: Neuron function is made possible in large part by the dynamic extension and retraction of dendrites, branches that reach out from cell-bodies of neurons to enable neuron-neuron interactions. During aging or resulting from disease processes, this branching can become disrupted, leading to altered neuron connectivity. For example, such changes occur in human pathologies like Alzheimer’s, schizophrenia, autism, bipolar disorder and cognitive deficits. A central biological puzzle that our laboratory addresses is mechanisms by which dendrites regulate their tree-like shapes. Ultimately, basic research aimed to provide insight on normal dendritic branching might assist clinicians in their work to treat or even correct abnormalities.
We recently discovered a “phospho-switch” that is contained within a key protein in our nervous system, delta-catenin. This phospho-switch determines delta’s ability to bind either of two novel protein partners. In helping to shape a normal dendritic tree, these two distinct delta-complexes produce different actions upon the neuron cytoskeleton to favor dendrite elongation versus dendrite branching.
Goals: We will employ primary rat hippocampal cultures, cell lines and in vivo models, to reveal upstream pathways (e.g. ligands and kinases) that control delta-catenin’s phospho-switch. We are also working to uncover delta’s downstream mechanisms of action that promote neuron branching versus lengthening. Interestingly, both delta-catenin and its novel protein partners have further roles in cancer progression. More broadly, our goal is to reveal the roles of less-understood catenins, to make possible an understanding of their distinct versus shared functions. Thus, the larger scope of our research interests includes the above-noted delta-catenin, and in addition, plakophilin3-catenin, p120-catenin, and ARVCF-catenin.
While distinct entities, each of these catenins shares homology with the well-established beta-catenin, and each is present in multiple cellular compartments. Like beta-catenin, each catenin binds to cadherin cell-cell adhesion proteins as well as nuclear factors. However, beta-catenin activates genes after binding to the TCF/ LEF transcription factor, whereas p120-catenin or delta-catenin (etc.) bind to other transcription factors to regulate gene activity. Over the years, our trainees have uncovered a spectrum of novel complexes and functions of delta-catenin, plakophilin3-catenin, ARVCF-catenin, p120-catenin and beta-catenin. For example, we revealed that the p120-catenin:Kaiso cooperates with the beta-catenin:TCF complex to regulate certain genes critical in development and cancer. Further upstream, we discovered that the stability of p120-catenin-isoform1 is regulated by the same components known to act upon beta-catenin. Unexpectedly, we revealed that p120-catenin binds and modulates the potent REST/ Co-Rest transcriptional complex that participates in stemness/ differentiation decisions. We went on to show that ARVCF-catenin is essential in vertebrate development and uncovered its direct interaction with the novel protein Kazrin, which modulates cytoplasmic small-GTPases and has junctional roles. When we evaluated delta-catenin, we surprisingly found it is positively regulated by caspase3 (non-apoptotic context) to generate a large fragment that enters the nucleus to bind/ modulate a novel gene repressor we named ZIFCAT. We also resolved plakophilin3-catenin's functional interaction with ETV1, a gene activator important in neural development. In the longer term, we aspire to determine the extent to which the combined functions of catenins are networked to meet an array of cellular and developmental goals. By addressing these questions, we will better confront the basis of catenin contributions to development, and to cancer and central nervous system diseases.View a complete list of Dr. McCrea's publications.
