Biografia

Kanagy received a BA in Chemistry from Goshen College (1984) and then worked for Miles Laboratories (Bayer Pharmaceuticals) before going to graduate school at Michigan State University where she received a PhD in Cardiovascular Pharmacology (1992). She completed a Postdoctoral fellowship at the University of Michigan in Cardiovascular Physiology (1995) before joining the department of Cell Biology and Physiology at the University of New Mexico School of Medicine as an Assistant Professor (1995). Kanagy has been part of the Vascular Physiology Group in the Cell Biology and Physiology Department since its formation in 2000.

Declaração pessoal

I have established a productive research laboratory as part of the Vascular Physiology Group at the UNM-HSC. I have also trained 10 PhD students, 6 post-doctoral fellows and numerous undergraduate students. I have an i10 index of 64 and an h-index of 34 with more than 80 publications. I have contributed to the Biomedical Sciences Graduate Program as a mentor, instructor, director and, most recently, as the Senior Associate Dean of Research Education. During my tenure in graduate education leadership we developed several new initiatives including enhanced regional recruitment, expanded professionalism training and additional options for students to prepare for non-academic careers. I also led the Signature Program in Cardiovascular and Metabolic Disease for almost 10 years, instituting an annual Research Symposium and overseeing the pilot grant program to grow the research community in this important area. With over 25 years of experience in cardiovascular research, I have successfully led multiple research projects. My background in vascular physiology includes experience in studying blood pressure regulation, vascular function in animal and human studies, renal function, electrophysiology, live cell calcium imaging, transcriptional regulation and intracellular signaling. Since my appointment as a tenure-track faculty member in 1995, I have been PI or co-Investigator on multiple university-, EPA-, AHA- and NIH-funded grants. I have ongoing collaborations with other members of the Vascular Physiology Group, members of the College of Pharmacy and several physicians including an endocrinologist, a vascular surgeon and a gastroenterologist.

Pesquisa

Minha pesquisa se concentrou em vários aspectos da fisiologia cardiovascular, com ênfase principal nos reguladores endógenos da função vascular periférica. Os estudos no início de minha carreira docente se concentraram no papel e na regulação dos receptores alfa 2 adrenérgicos e forneceram algumas das bases iniciais para o estabelecimento desse subtipo de receptor como contribuinte para a vasoconstrição, especialmente em artérias doentes. Outros estudos em colaboração com o Professor Matthew Campen investigando o impacto de poluentes inalados na função vascular observaram comprometimento da função da artéria coronária em ratos após a inalação de concentrações relevantes de partículas de exaustão de diesel, fornecendo uma base fisiológica para eventos coronários elevados em indivíduos que vivem em áreas com níveis elevados de poluentes veiculares. Colaborações com os professores Benjimen Walker e Leif Nelen desenvolveram um modelo de apnéia do sono em ratos para estudar os mecanismos que levam ao aumento da pressão arterial com exposição crônica à hipóxia durante o sono. Descobrimos que as elevações no peptídeo vasoconstritor, endotelina, contribuíram para o aumento da pressão arterial. Meu laboratório determinou que a apnéia do sono simulada também prejudica a função endotelial por meio de deficiências na vasodilatação dependente de sulfeto de hidrogênio. O trabalho desde então se concentrou na decifração da via vasodilatadora desse novo vasodilatador endógeno e publicamos vários estudos importantes que mostram como essa molécula regula a função vascular. Este trabalho é o foco de projetos atuais, incluindo um estudo clínico investigando o uso de um novo sensor transdérmico para avaliar a correlação da produção de sulfeto de hidrogênio vascular com marcadores conhecidos de doença microvascular.

My current work is investigating signaling in the vasculature by the recently described vasodilator, hydrogen sulfide H2S. These studies are some of the first to look at H2S signaling in vascular endothelial cells to cause vasodilation. These studies have identified two animal models with decreased levels of H2S, intermittent hypoxia as a model of sleep apnea and adenine feeding-induced chronic kidney disease. This work is most relevant to the current application and demonstrates my ability to generate and work with animal models and to evaluate H2S signaling. a.

Em colaboração com o Dr. Benjimen Walker, we developed an intermittent exposure animal model to investigate the role of elevated endothelin synthesis in the hemodynamic and vascular changes observed with chronic sleep apnea. These studies were some of the first to link endothelin to the hypertension that develops in response to the intermittent hypoxia of sleep apnea. a.
