Charles Wiener Lab
The Charles Wiener Lab primarily conducts research on pulmonary circulation and hypoxia as well as respiratory muscle function in patients with neuromuscular diseases. Our recent studies have included investigating the treatment of pericardial effusions in patients with pulmonary arterial hypertension and examining the use of non-invasive ventilation in patients with amyotrophic lateral sclerosis (ALS). We also have an interest in medical education research. Our work in this area has included reviewing the role of academic medical centers in emerging health care markets.

Gilkes Lab
Our lab is focused on determining the role of hypoxia in breast cancer metastasis. We are particularly interested in the changes in the extracellular matrix that occur under hypoxic conditions and promote cancer cell migration.
-
Gregg Semenza Lab
The Gregg Semenza Lab studies the molecular mechanisms of oxygen homeostasis. We have cloned and characterized hypoxia-inducible factor 1 (HIF-1), a basic helix-loop-helix transcription factor.
Current research investigates the role of HIF-1 in the pathophysiology of cancer, cerebral and myocardial ischemia, and chronic lung disease, which are the most common causes of mortality in the U.S. -
Jonathan Jun Lab
The Jonathan Jun Lab studies the function of lipolysis in intermittent hypoxia-induced insulin resistance.

Kristine Glunde Lab
The Glunde lab is within the Division of Cancer Imaging Research in the Department of Radiology and Radiological Science. The lab is developing mass spectrometry imaging as part of multimodal molecular imaging workflows to image and elucidate hypoxia-driven signaling pathways in breast cancer. They are working to further unravel the molecular basis of the aberrant choline phospholipid metabolism in cancer. The Glunde lab is developing novel optical imaging agents for multi-scale molecular imaging of lysosomes in breast tumors and discovering structural changes in Collagen I matrices and their role in breast cancer and metastasis.

Larissa Shimoda Lab
Research in the Larissa Shimoda Lab focuses on several important topics within pulmonary and critical care medicine. We primarily study pulmonary arterial responses to chronic hypoxia as well as hypoxic pulmonary vasoconstriction and oxidant-mediated lung injury. Our recent research has included investigating the effects of chronic hypoxia on pulmonary circulation and the ways in which hypoxia-inducible factors impact pulmonary vascular responses to hypoxia. We have also studied vascular remodeling in patients with pulmonary hypertension.

Mahendra Damarla Lab
Work in the Mahendra Damarla Lab focuses primarily on the field of vascular biology. Much of our research involves exploring alternatives to mechanical ventilation as a therapy for acute lung injury. We investigate mitogen-activated protein kinase-activated protein kinase 2 as a method to mediate apoptosis during lung vascular permeability by regulating movement of cleaved caspase 3. We have also conducted research on the prevalence of confirmatory tests in patients hospitalized with congestive heart failure or chronic obstructive pulmonary disease (COPD).

Marie-France Penet Lab
The Penet lab is within the Division of Cancer Imaging Research in the Department of Radiology and Radiological Science. The lab research focuses on using multimodal imaging techniques to better understand the microenvironment and improve cancer early detection, especially in ovarian cancer. By combining MRI, MRS and optical imaging, we are studying the tumor microenvironment to understand the role of hypoxia, tumor vascularization, macromolecular transport and tumor metabolism in tumor progression, metastasis and ascites formation in orthotopic models of cancer. We also are studying the role of tumor-associated macrophages in tumor progression.

Mark Liu Lab
Research in the Mark Liu Lab explores several areas of pulmonary and respiratory medicine. Our studies primarily deal with allergic inflammation, chronic obstructive pulmonary disease (COPD) and asthma, specifically immunologic responses to asthma. We have worked to develop a microfluidic device with integrated ratiometric oxygen sensors to enable long-term control and monitoring of both chronic and cyclical hypoxia. In addition, we conduct research on topics such as the use of magnetic resonance angiography in evaluating intracranial vascular lesions and tumors as well as treatment of osteoporosis by deep sea water through bone regeneration.
-
Robert Fitzgerald Laboratory
The Robert Fitzgerald Laboratory studies cardiopulmonary physiology, especially cardiopulmonary control. We have focused in particular on the operation of the carotid body and the role of acetylcholine in its functioning. We have also examined the reflex effects of carotid body stimulation in various organs as well as the reflex response of ACTH and adrenal cortical hormones to hypoxic peripheral arterial chemoreceptor stimulation. We are currently interested in the spleen, as it is the only organ other than the lung that demonstrates increased vascular resistance in response to local hypoxia.

Sleep Apnea Pathogenesis
Our research laboratory is staffed by a dedicated and experienced team of sleep scientists, fellows, technicians, engineers, and students. Currently, we are focused on the following areas:
-Novel treatments for sleep apnea using electrical and nerve stimulation and chemogenetic techniques
-Cardiovascular and metabolic effects of sleep apnea and hypoxia
-Leptin and its impact on breathing and cardiovascular physiology
-Sleep disordered breathing at high altitude
-Dietary impacts on asthma -
Vsevolod Polotsky Lab
The Vsevolod Polotsky Lab conducts research on pulmonary diseases, including hypoxia and sleep apnea, with a focus on their relation to obesity and metabolic syndrome. Our studies have explored topics such as the effects of age, leptin and obesity on the upper airway; the relationship between obstructive sleep apnea, insulin resistance and steatohepatitis in severely obese patients; and the impact of intermittent hypoxia on diet-induced obesity. We also have a long-standing interest in critical care pulmonary medicine and have conducted research on various aspects of murine lung injury.

Zaver M. Bhujwalla Lab – Cancer Imaging Research
Dr. Bhujwalla’s lab promotes preclinical and clinical multimodal imaging applications to understand and effectively treat cancer. The lab’s work is dedicated to the applications of molecular imaging to understand cancer and the tumor environment. Significant research contributions include 1) developing ‘theranostic agents’ for image-guided targeting of cancer, including effective delivery of siRNA in combination with a prodrug enzyme 2) understanding the role of inflammation and cyclooxygenase-2 (COX-2) in cancer using molecular and functional imaging 3) developing noninvasive imaging techniques to detect COX-2 expressing in tumors 4) understanding the role of hypoxia and choline pathways to reduce the stem-like breast cancer cell burden in tumors 5) using molecular and functional imaging to understand the role of the tumor microenvironment including the extracellular matrix, hypoxia, vascularization, and choline phospholipid metabolism in prostate and breast cancer invasion and metast...asis, with the ultimate goal of preventing cancer metastasis and 6) molecular and functional imaging characterization of cancer-induced cachexia to understand the cachexia-cascade and identify novel targets in the treatment of this condition. view more
