Biography
A. PERSONAL STATEMENT
My transition from neuroscientist to oral biologist has been a circuitous but very rewarding journey. Upon joining Creighton’s Dental School, I sought to mesh my background with the research interests and needs of the clinical departments, particularly Periodontics and Oral and Maxillofacial Surgery. In collaboration with the Chairs and faculty of both departments we initiated primary human oral fibroblast studies with lysophosphatidic acid [(LPA), a lipid mediator which I had worked with during my studies in the lung system at the University of Nebraska Medical Center, Department of Pharmacology. At that time, LPA and its actions had never been described in the dental literature. Based on pilot studies, I hypothesized that it might be a candidate factor for periodontal regeneration. Over the twenty years that I have been teaching/research faculty in the Dental School, I have served as the P.I. of the seminal studies that have established the essential role of LPA in human oral fibroblast biology, and we have accumulated a large body of knowledge and expertise in wound-healing and inflammation, particularly in the oral system. For our studies- both NIH- and foundation-supported- we have involved dental and undergraduate students, and collaborated with clinicians and researchers at Creighton, our Dental School, and at the University of Nebraska Medical Center. Our discovery that LPA significantly and extensively regulates inflammatory transcripts in human oral fibroblasts and is very likely a pivotal regulatory mediator in human periodontal disease now opens the way for studying the role of LPA species and LPA receptor subtypes in the pathogenesis of periodontal disease. To this end, we will further the in vitro studies by proposing to determine LPA’s role in inflammatory periodontal disease using an established mouse model of this disease.

D. CONTRIBUTION to SCIENCE
1. Human Oral Fibroblast Physiology: Since 1999, I have engaged in collaborative research with dental clinical faculty in Periodontics and in Oral and Maxillofacial Surgery. Our foundational studies funded by the Health Futures Foundation showed that lysophosphatidic acid (LPA) controlled the healing responses of human oral fibroblasts. We found that LPA was a major regulatory factor for these cells, and published these seminal LPA papers in the dental literature; they are now being referenced and used by other investigators to widen the investigation on the role of LPA in oral cell biology and periodontal disease.

Lysophosphatidic acid modulates the regenerative responses of human gingival fibroblasts and enhances the actions of platelet-derived growth factor. J Periodontol. 2004 Feb;75(2):297-305.PMID:15068119.

J Periodontol. 2007 Jun;78(6):1136-45.PMID:17539729.
2. LPA Receptor Subtype Regulation of Oral Fibroblast Physiology: I then used the data from the papers above to submit an R15 application to the NIH/NIDCR which was funded on the initial round. LPA had only recently begun to be appreciated by the larger scientific community in other fields as a key regulatory molecule participating in a multitude of homeostatic and pathophysiological processes. The study below established the pivotal role of the main human salivary LPA species in differentially regulating human oral fibroblast physiology:

Lysophosphatidic Acid signals through specific lysophosphatidic Acid receptor subtypes to control key regenerative responses of human gingival and periodontal ligament fibroblasts. J Periodontol. 2009 Aug;80(8):1338-47. PMID:19656035.
With a small grant from Becton-Dickinson, we used flow cytometry to profile LPA receptor subtype expression on oral fibroblasts from multiple donors, and showed that they express the first five (LPA1-5) of the six LPARs cloned to date. The expression of so many LPAR subtypes supports our proposition that LPA plays an essential role in oral fibroblast biology.

3. Analytical Saliva Studies: To investigate the association of LPA with periodontal disease, we developed a sensitive LC-MS/MS method to analyze LPA species in saliva and gingival crevicular fluid (GCF). We found the LPA species unchanged in ratios, but a 10-fold, pharmacologically significant elevation in moderate-severe periodontal disease. This method remains one of the most sensitive published to date for LC-MS/MS analysis of LPA species in saliva and GCF.

4. Gene regulation by LPA: As LPA controlled such critical aspects of oral fibroblast biology, we did a pilot microarray study with LPA-stimulated GF. Based on these data, we hypothesized that exposure to LPA would modulate GF expression of various categories of critical genes that orchestrate wound-healing and inflammatory responses. Then, using GF from multiple donors, we showed extensive gene expression changes correlated with LPA treatment. The significantly changed genes and the derived biological networks we reported suggested major regulation of genes involved in orchestrating inflammatory-type responses of oral fibroblasts to LPA.

b. Cerutis DR, Weston MD, Alnouti Y, Bathena SP, Nunn ME, Ogunleye AO, McVaney TP, Headen KV, Miyamoto T. A Major Human Oral Lysophosphatidic Acid Species, LPA 18:1, Regulates Novel Genes in Human Gingival Fibroblasts. J Periodontol. 2015 May;86(5):713-25. PMID:25660500
5. Future Studies: LPA is a highly conserved molecule with profound regulatory actions in health and disease. Except for my laboratory, LPA has received relatively little attention aimed at deciphering its role in oral homeostasis and periodontal disease. One of the two major sources of LPA is activated platelets, which are always present in the inflamed periodontium due to the tissue destruction and bleeding characteristic of moderate-severe periodontal disease. The results of our seminal body of work now suggest that LPA likely modulates oral fibroblast inflammatory responses and their interactions with neutrophil / lymphocyte chemotactic and immune events in the periodontium. Ultimately, LPA may participate in regulating inflammation in periodontal disease, where the balance of destruction of gingival tissue, periodontal ligament, and alveolar bone in response to periodontal pathogens determines disease status and progression. Taken together, LPA merits further investigation of its regulatory role in the oral system; we continue these investigations.
