Daniel Michele, PhD

Lab focus: Muscles from muscular dystrophy patients and mouse models with mutations in the dystrophin glycoprotein complex also show marked sensitivity to contraction induced injury. This is in part thought to be due to a structural role for the complex in stabilizing the sarcolemma during mechanical stress. Muscle has developed a remarkable ability to repair the sarcolemma after injury, a process that is mediated in part by the protein dysferlin. Dysferlin is mutated in patients with LGMD 2B and Myoshi myopathy. We have developed methodologies to watch the membrane repair pathway activation in real time using live cell microscopy and transgenic mice expressing GFP reporter constructs that show the localization and orientation of dysferlin in the muscle fiber membrane. We are utilizing these mice to study the mechanisms of how the membrane repair pathway is regulating following experimental and physiological muscle injury.

Experience required: Previous cell culture or microscopy experience is a plus.

Project description: We are using live cell microscopy approaches in isolated muscle fibers from mice, and human cell derived engineered muscle tissues to study and compare how muscles repair membrane injuries in skeletal muscle and heart tissues. The project is aimed at studying how repair mechanisms are activated at the wound site, and how injury propagation through fibers or into neighboring coupled cardiac muscle cells temporarily uncouple normal excitation contraction coupling leading to muscle contractile dysfunction.

Dinesh Pal, PhD

Lab focus: The overarching goal of our research program is to understand the neural regulation of states of arousal such as sleep, wake, anesthesia, and altered states produced by psychedelic compounds. In addition to our focus on understanding the neural circuits and processes that underlie the generation of these states, we use these natural and pharmacologically induced states as model systems to study the neural substrates of consciousness. We are also conducting studies to understand the interaction between sedation and sleep homeostasis. A mechanistic study of these varied states of arousal and the larger question of consciousness are not only important for a better understanding of fundamental neurobiological principles but also have a direct translational impact. The ability to manipulate wake-promoting circuits to enhance recovery of consciousness from unconscious states has the potential to help expedite recovery from disorders of consciousness and possibly from anesthesia. Insights into the effect of sedative-hypnotics on sleep homeostasis will allow for the characterization of a sedative regimen that may provide sleep-like benefits and facilitate patient recovery in perioperative and critical care. Our work with psychedelic compounds can inform the possibility of using psychedelics to treat sleep disorders either directly through effect on sleep-wake states or indirectly by managing depression and anxiety and can provide guidance on sleep health at the community level. These studies are also expected to provide mechanistic insights for therapeutic use of psychedelic compounds in psychiatry and neurology.

Experience required: Prior experience with lab animal research is preferred, but not required. Training will be provided for the skills needed for the study completion.

Project description: It is not clear if and how sedative-hypnotics can provide a sleep-like state associated with positive functional outcomes. To test this hypothesis, we are conducting studies to compare the molecular changes - adenosine and nitric oxide - in the sleep-wake related brain regions during natural sleep and sedation. There are multiple approaches - e.g., neurotransmitter sampling, immunohistochemical staining, protein/enzymatic analysis - that can be employed and the project offers a wide array of opportunities for training and addressing an important question with significant translational impact.

Thomas Sanderson, PhD 

Lab focus: Research in the Sanderson lab is focused on understanding brain damage caused by ischemic insults during cardiac arrest, ischemic stroke, and neonatal hypoxia/ischemia. Ongoing mechanistic studies are focused on uncovering novel pathologic mechanisms of inner mitochondrial membrane proteins involved in mitochondrial dynamics, quality control, cristae maintenance, and cell death execution. These studies utilize novel cell and small animal models of brain ischemia in transgenic mice to evaluate mitochondrial dysfunction. A second area of focus is the development and clinical translation of neuroprotective therapies that modulate the activity of mitochondria to reduce brain injury. Pre-clinical large animal studies are ongoing to evaluate a novel therapeutic strategy that limits mitochondrial hyperactivity and prevents ROS production following brain ischemia. Ongoing studies supported by the NIH and DoD are focused on investigating the mechanisms of this therapy through continued testing in large animals, along with regulatory testing of human therapy devices that can bring this treatment to the clinic.

Yatrik Shah, PhD

Lab focus: The major goal of our research program is to determine the molecular mechanisms by which oxygen sensing transcription factors regulate gastrointestinal homeostasis, inflammation and cancer. Cellular oxygen level is an important systemic signal that modulates metabolic activities and disease in the liver and intestine. Low cellular oxygen also referred to as hypoxia is observed in several gastrointestinal diseases such as non-alcoholic and alcoholic fatty liver disease, inflammatory bowel disease and liver and colon cancers. Regulation of hypoxia-mediated genes is dependent on the nuclear transcription factor, hypoxia inducible factor (HIF). HIF signaling is critical in the adaptive response to low oxygen levels by activating genes involved in metabolism, angiogenesis, cell survival and iron metabolism. Using the latest in mouse transgenic technology we have developed novel animal models to study accurately the role of oxygen sensitive transcription factors in the liver and intestine. These studies have revealed new pathways that have not previously been associated with hypoxia.

Experience required: Will train. Must be willing to work with animals.

Project description: Exploring the role of oxygen signaling in intestinal cancer. With a focus on one of these three projects – (i) The role of hypoxia inducible factor (HIF) in iron metabolism, (ii) The role of intestinal epithelial-elicited inflammation in cancer progression, or (iii) The role of HIF in regulating systemic glucose and lipid metabolism

Lei Yin, PhD

Lab focus: The Yin lab is interested in the physiology and pathology of liver metabolism and liver metabolic diseases, such as Alcoholic liver disease and diabetes. Both genetic mouse models and in vitro hepatocyte culture are currently used in the lab to address the impact of dys-regulation of molecular circadian clock on the susceptibility of alcohol feeding on liver injury and liver lipid metabolism. Yin lab is currently developing a protocol to use CRISP-CAS9 system to generate liver-specific knockout and knockin mouse models for specific clock gene.  

Experience required: Experience working in the lab during college will be desirable.

Project description: The project will examine the cross-regulation between E4BP4 and PPARalpha pathway during hepatic ER stress. E4BP4 is the circadian output transcription factor. Our previously studies showed that E4BP4 potently suppresses hepatic hormone Fgf21 during feeding state. Our further analysis suggests that E4BP4 could be an important suppression of hepatic fatty acid oxidation pathway by inhibiting PPARalpha, which is the major regulator of hepatic fatty acid oxidation. The project will address the following questions: (1) At the molecular level how does E4BP4 suppresses PPARalpha transcription activity; (2) Is E4BP4 required for PPARalpha suppression during hepatic ER stress, including alcohol feeding and sepsis.
