Mentors: Arohan Subramanya, MD / Tom Kleyman, MD
Career Development Award: NIDDK K08
Research
As a physician-scientist, Dr. Boyd-Shiwarski’s research focuses on the role of dietary potassium in hypertension and chronic kidney disease. Deficiencies in dietary potassium are known to increase blood pressure and increase the progression of chronic kidney disease (CKD). Unfortunately, there are large gaps in scientific knowledge regarding how and why potassium deficiency leads to hypertension and CKD. This project focuses on the effect of potassium depletion at the molecular level, studying potassium sensing and handling by the kidney. Her laboratory has identified a complex of WNK (with-no-lysine) kinases that form signaling microdomains in the kidney during potassium depletion and refers to these complexes as “WNK bodies”. In recent years, there has been a growing appreciation that the cytosol can demix into distinct microdomains, to concentrate and control biological processes. Thus, the WNK bodies appear to represent a new type of “biomolecular condensate” that concentrates WNK-dependent signaling processes in the kidney in response to potassium depletion. The formation of the WNK body microdomain is dependent upon the expression of kidney-specific WNK1 (KS-WNK1). By studying mice that are unable to form WNK body complexes (KS-WNK1-/- mice), she is beginning to understand the role of WNK bodies during potassium disequilibrium.

Research
My research focuses on understanding and targeting the cancer supporting stromal tissues which are critical to the survival, growth and spread of ovarian cancer. Specifically, my lab studies a critical non-malignant component of the ovarian cancer microenvironment, the carcinoma-associated mesenchymal stem cell (CA-MSC). CA-MSCs are stromal progenitor cells which significantly increase cancer growth, enrich the cancer stem cell pool and increase chemotherapy resistance.
My lab studies how CA-MSCs are formed and develop tumor supporting properties. My lab also focuses on identifying important tumor cell:CA-MSC interactions which mediate CA-MSC’s pro-tumorigenic functions and have potential for translation into new therapeutic targets. Additionally, we study how CA-MSCs impact the development of ovarian cancer metastasis and the metastatic microenvironment.
The ultimate goal of my research is to translate novel laboratory findings into powerful therapeutic approaches for the prevention and treatment of ovarian cancer.

Career Development Award: NHLBI K99/R00
Research
My research aims to better understand the physiological and pathophysiological roles of the smallest molecules found in biology: nitric oxide (NO), hydrogen sulfide (H2S/HS-), and carbon monoxide (CO). Commonly known as toxic by-products from anthropogenic sources, these molecules (often referred to as “gasotransmitters” or “diatomic bioregulators”) are also produced via endogenous metabolic processes in living systems throughout all kingdoms of life. In humans, these molecules are involved in signaling cascades that regulate vascular tone, inflammation, circadian rhythm, sensory perception, and cell proliferation, among many others. As the scope of these critical signaling molecules continues to grow, new tools are needed to assess their spatiotemporal dynamics in living systems. My work couples techniques in protein engineering and biochemistry with cellular and preclinical animal models to 1) develop new treatment strategies for toxic exposure to these diatomic molecules, and 2) design and implement molecular visualization tools that can be used to understand how these molecules function as bioregulatory signals. Specifically, this project focuses on engineering a selective, high-affinity CO sensor protein from bacteria into a CO-scavenging therapeutic to treat acute CO poisoning. Using the same protein scaffold, I also seek to develop a genetically encoded fluorescent reporter that can be used to track endogenous CO signaling dynamics in cells and living organisms.

John Evankovich III, MD
Division/Institute: Pulmonary, Allergy and CCM
Mentor: Bill Chen, PhD
Career Development Award: NHLBI K08
Research
Dr. Evankovich studies the molecular biology of lung injury. His laboratory is interested in the intersection of three molecular systems in the innate immune system, and how they influence inflammation and cell death pathways in the lung. The molecular systems are Damage Associated Molecular Patterns (DAMPs), DAMP Receptors, and the Ubiquitin/Proteasome System (UPS).
Dr. Evankovich’s prior work has identified how several novel DAMP/DAMP receptor pairs are processed for disposal in the UPS, and how this process can be manipulated to change subsequent cellular responses. For damaging responses, increasing targeted DAMP receptor disposal through the UPS could lessen organ damage; likewise, for protective DAMP/DAMP receptor pairs, reducing disposal in the UPS could be therapeutic to reduce injury.
Teaming with the Small Molecule Therapeutics Center, Dr. Evankovich’s future work aims to discover novel small molecules to disrupt these pathways and test in preclinical models of lung injury. He is also an Associate Member of the Aging Institute, where he focuses on the contribution of aging to innate immune responses in the lung.

Research
Heart failure with preserved ejection fraction (HFpEF) accounts for roughly half the cases of heart failure in the United States. HFpEF is a complex syndrome that presents with diastolic dysfunction, and is associated with comorbidities like obesity, hypertension, diabetes and metabolic syndrome. The underlying pathophysiology of HFpEF is not well understood. A key clinical finding in HFpEF is extensive cardiac remodeling and is associated with the systemic inflammation and metabolic syndrome, commonly observed in HFpEF patients. I am interested in the inflammatory signaling pathways that mediate cardiac remodeling, particularly through macrophages and complement signaling mechanisms. My work focuses on understanding the cross-talk between inflammatory signals and cardiac fibroblasts that lead to cardiac remodeling using a systems approach with combination of in vivo and in vitro models.

Obesity is a significant factor in the development of various pathologies, such as type 2 diabetes, cardiovascular disease, and cancer. Recent research has demonstrated the crucial role of calcium ion (Ca2+) signals in lipid metabolism and transcriptional reprogramming of cells to support proliferation and development. Orai proteins, specifically Orai1-3, are highly selective channels for Ca2+ and serve as universally present and evolutionarily conserved pathways for regulated Ca2+ influx into all cells. They play a pivotal role in numerous cellular and physiological functions, including the process of lipolysis, proliferation, and development. The primary focus of my work involved investigating the role of Ca2+ entry through Orai channels in various aspects, including metabolism, neuronal development, neuronal activation, and its impact on the regulation of thermogenesis and obesity.

Dr. Puttarajappa’s research is focused on evaluating the role of virtual HLA crossmatch for deceased donor kidney transplantation(DDKT). Several logistical issues complicate kidney allocation and organ placement, thereby increasing ischemia times and risk of organ discards. Dr. Puttarajappa is investigating the potential benefits of omitting a cell-based (physical) HLA crossmatch and proceeding to transplant surgery with just the result of a virtual HLA crossmatch. He is using a combination of transplant registry analysis, survey methodology and decision analysis to evaluate the impact of virtual HLA crossmatch on cold ischemia time and transplant outcomes, variation in practice across US transplant centers and the risks and benefits of using a virtual crossmatch strategy over a cell-based HLA crossmatch strategy. His other research interests include application of decision and cost-effectiveness analyses to transplantation and evaluating methods to reduce detrimental impact of modifiable post-transplant events such as late-onset CMV infection and immunosuppression non-adherence.
