Awards and Fellowships:

 

Congratulations to Kelly Barford, who was awarded an Ruth L. Kirschstein National Research Service Award Fellowship:

Kelly Barford

A Neuroscience Ph.D candidate in the lab of Dr. Bettina Winckler has received a Ruth L. Kirschstein National Research Service Award for Individual Predoctoral Fellows from the National Institutes of Health entitled “Novel Endosomal Pathways Underlying NGF/TrkA Dependent Dendrite Development.” Neurons are unique cells in many ways including their large size. Protein trafficking is involved in all aspects of neuronal function including development, axon/dendrite growth, and synaptic function. Neurons express special endosomal machinery to regulate protein trafficking, and peripheral neurons in particular are in distinct need of specialized protein transport due to their length. One receptor that is critical for the development of the sympathetic nervous system, TrkA, has been shown to undergo complex trafficking events. My goal is to uncover the molecular mechanisms, trafficking molecules, and signaling cascades involved in long-distance synapse assembly by the neurotrophin-TrkA signaling endosome, a pathway recently discovered and not widely studied. This will provide insights into the development of the sympathetic nervous system as well as overall synapse assembly to form a functional nervous system.

Bryan Barker

A neuroscience Ph.D candidate in Manoj Patel’s lab has received the American Epilepsy Society’s Predoctoral Fellowship for his dissertation work in the field of epilepsy “The role of T-type calcium channels in neuronal hyperexcitability in the subiculum in temporal lobe epilepsy.” Temporal lobe epilepsy (TLE) is a debilitating neurological disorder that is characterized by recurrent spontaneous seizures that originate in the temporal lobe of the brain. There is no cure for TLE; seizures can only be suppressed using anticonvulsant drugs. Despite a plethora of treatment options, 30% of TLE patients do not respond to any currently available therapies. To improve treatment efficacy it is essential to develop a better understanding of the alterations in neuronal physiology that occur during the development of epilepsy and how these changes ultimately culminate in the occurrence of spontaneous seizures. My dissertation research focuses on the understudied subiculum, a brain region that acts as the output of the hippocampus. Specifically, my goal is to understand how alterations in T-type calcium channel activity in TLE, lead to the increase in neuronal activity associated with seizure initiation.


 

Congratulations to Alex Keller, who was awarded an American Heart Association Predoctoral Fellowship:

Alex Keller

Alex Keller, a Pharmacology Ph.D. candidate in Brant Isakson’s laboratory has received a pre-doctoral fellowship from the American Heart Association to research “Mechanisms of ATP release from Pannexin 1 in Red Blood Cells in response to hypoxia.” Regulation of blood flow to supply oxygen at an appropriate rate to meet the metabolic demand of tissues across the body is an imperative homeostatic process. Red blood cells have been shown to release ATP in response to hypoxic conditions, resulting in arteriolar dilation in a manner that could contribute to increased perfusion of hypoxic tissues. However, the details of the ATP release mechanism from red blood cells in this context are unclear. Pannexin 1, a channel believed to be involved in this ATP release pathway, is of particular interest to the Isakson lab. By studying the activation of Pannexin 1 in this context, Alex seeks to elucidate the molecular pathway underlying ATP release from red blood cells in response to hypoxia. In addition, he plans to use modern techniques to study the broader pathway in more physiologically relevant contexts than those in which it has previously been examined. Overall, this research will improve our understanding of an important mode of blood flow regulation while simultaneously offering an opportunity to learn more about under-studied red blood cell signaling mechanisms.


 

Congratulations to Steven Keller, who was awarded an American Heart Association Predoctoral Fellowship:

Steven Keller

A Molecular Physiology and Biological Physics graduate student co-mentored by Linda Columbus and Brant Isakson has received an American Heart Association Pre-Doctoral Fellowship. “Increasing nitric oxide (NO) via an alpha globin mimetic peptide as a treatment for sickle cell-induced pulmonary hypertension.” Endogenously produced NO is one of the most potent mechanisms to maintain blood pressure homeostasis. A recently discovered regulator of NO production in vascular endothelium is the direct interaction of endothelial nitric oxide synthase (eNOS) and the alpha chain of hemoglobin, putting a sink for NO in complex with its source. We are using a peptide mimicking the binding sequence of alpha globin to disrupt alpha globin/eNOS complex formation and increase NO availability, thus lowering blood pressure. Structural aspects of this interaction are being investigated in the context of hypertensive pathologies, especially pulmonary hypertension, a common condition in sickle cell disease that is associated with high mortality.


 

Congratulations to Aldo Nascimento, who was awarded a National Cancer Institute NRSA Predoctoral Fellowship:

Aldo Nascimento

Mitochondria are highly dynamic, and the fusion and fission of mitochondria represent an increasingly important, but poorly understood node of cellular regulation. Recent studies have shown that defects in the fusion-fission balance have detrimental effects on human health including an involvement in diabetes and cancer. Further, many of the processes regulated by mitochondrial dynamics overlap with those that are induced by oncogenic Ras signaling. We have recently published data which demonstrates that activated Ras can signal through the MAPK pathway to promote mitochondrial fission. This mitochondrial fission in turn is important for MAPK-driven tumor growth. What remains to be understood is why the mitochondrial fission is important for tumor growth. Thus, we now shift our focus to determine which physiological processes necessary for tumor growth are regulated by an increase in mitochondrial fission. If successful, these studies will reveal a novel, physiologically relevant mechanistic insights of how Ras-induced mitochondrial fission promotes tumor growth. Furthermore, these studies will elucidate novel regulatory mechanisms of mitochondrial dynamics and potentially provide novel therapeutic targets for the treatment of Ras-driven cancers.


 

Congratulations to Tori Osinski, who was awarded an American Heart Association Predoctoral Fellowship:

Tori Osinski

A Pathology Ph.D. candidate in the lab or Coleen McNamara has received an American Heart Association Predoctoral Fellowship. “Assessing regulation of adipose tissue angiogenesis by Id3 and MCP-1-expressing adipocyte progenitor cells.” Adipose tissue (fat) expansion involves two important processes: adipogenesis, the formation of new adipocytes (fat cells), and angiogenesis, the formation of new microvascular blood vessels. Defects in either can prevent proper growth of fat tissue during both normal development as well as pathological states such as obesity. Our lab has recently demonstrated a role for the transcription factor Inhibitor of differentiation 3 (Id3) in both of these processes. Id3 regulates the proliferation of adipocyte progenitor cells, which express high levels of Monocyte Chemoattractant Protein-1 (MCP-1). MCP-1 is a secreted molecule that influences monocyte and macrophage movement within tissues and macrophages play important roles in regulating inflammation and angiogenesis. I seek to identify the specific molecular and cellular roles of Id3, adipocyte progenitor cells, and macrophages in angiogenesis during adipose tissue expansion. The overall goal of this study is to better understand what goes on in adipose tissue during metabolic disorders such as obesity.

Congratulations to Dr. Edward Egelman, whose work was featured on the cover of the Biophysical Journal (23 February, 2016). The figure “shows a β-sheet formed by strands coming from three different protein subunits in the type VI secretion system sheath from Vibrio cholera. This structure was solved by cryo-EM at a resolution that allowed a full atomic model to be built for the large assembly.” (E.H. Egelman and A. Engel. 2016. Biophysical Journal 110:E01).
