Congratulations Chongyang on your PNAS Paper!

Thursday, August 5, 2021

A new study led by Chen Yan, Professor in the Aab Cardiovascular Research Institute and Chongyang Zhang, PhD student in the Department of Pharmacology and Physiology is published in PNAS. This study entitled "Cyclic Nucleotide Phosphodiesterase 1C Contributes to Abdominal Aortic Aneurysm" reveals an important molecular target, PDE1C, in the pathogenesis of abdominal aortic aneurysm (AAA).

AAA represents a significant aorta disease, having a mortality rate of 90% and being currently ranked as the 13th leading cause of death in the US, while this disease lacks effective therapeutics to prevent aneurysm progression. This study highlights an induction of cyclic nucleotide phosphodiesterase 1C (PDE1C) in smooth muscle cell–like cells of human and mouse AAA.

Using genetic approaches, it has been demonstrated a causative role of PDE1C in experimentally induced AAA. More importantly, this study revealed that pharmacological PDE1 inhibition attenuated the progression of pre-established AAA. Mechanistically, PDE1C-controlled cAMP suppresses smooth muscle cell senescence and AAA development through cAMP-mediated direct interaction and activation of SIRT1. Given that PDE1 inhibitors have been proposed in clinical trials, findings from this study may have high therapeutic significance for the potential of using PDE1 inhibitors in treating AAA. 

“Experimental evidence suggesting the role of cellular senescence in accelerated vascular aging are just surfacing. Our study provides insight that smooth muscle cell senescence could be an important factor that drives the pathological development of degenerative aneurysm disease.” said Chongyang Zhang, the co-first author of the study. “Our findings provide evidence that PDE1C elevation links SMC senescence to AAA development in both experimental animal models and human AAA, suggesting therapeutical significance of PDE1C as a potential target against aortic aneurysms.”

The Wallace O. Fenn Award – Dr. Brandon Berry

Friday, May 21, 2021

Berry

Dr. Brandon Berry

Dr. Brandon Berry was awarded the Wallace O. Fenn Award -- The award is given annually to a graduating student judged to have performed meritorious research and presented an excellent Ph.D. thesis. Congrats Brandon!

Dr. Brandon Berry studied mitochondrial bioenergetics and hypoxic signaling in the laboratory of Dr. Andrew Wojtovich. As a graduate student, Brandon developed and pioneered an optogenetic approach to control mitochondrial function using light. Using this approach, he discovered how changes in mitochondrial bioenergetics are required for protection against damaging hypoxia. Brandon was a leader in the laboratory and was dedicated to both his work and his colleagues. During his graduate school tenure, he was awarded an American Heart Association Fellowship, a Young Investigator Award from the Society for Redox Biology & Medicine, and published eleven manuscripts.

Alexander Milliken awarded a two-year AHA Predoctoral Fellowship

Thursday, April 1, 2021

Congratulations to Alexander Milliken, graduate student in the CMPP program, laboratory of Dr. Paul Brookes. Alex was recently awarded a two-year AHA Predoctoral Fellowship entitled, "Succinate dynamics and pH in cardiac ischemia-reperfusion injury".

Project Summary:

Ischemia-reperfusion (IR) injury is caused by the disruption of blood flow (ischemia), followed by its restoration (reperfusion), and is relevant to pathologies such as myocardial infarction (heart attack) and stroke. The accumulation of the Krebs' cycle metabolite succinate and cytosolic acidification are both hallmarks of ischemia. Tissue reperfusion is necessary to salvage ischemic myocardium, but it paradoxically triggers events that lead to cell death. The oxidation of accumulated succinate at mitochondrial complex-II (Cx-II) drives reactive oxygen species (ROS) generation. This ROS originates from reverse electron transport (RET) at complex-I (Cx-I), or from complex-III (Cx-III) and is presumably the major driver of injury. However, only a small portion of the accumulated succinate is oxidized. A majority is actually released from the cardiomyocyte and the heart altogether in a pH-dependent process where its extracellular role is unknown. Extending ischemic acidosis ("acidic post-conditioning" or acid PostC) into reperfusion is cardioprotective against IR injury, but the mechanism is not fully understood. My project aims to understand the interplay of pH and succinate (oxidation v. release) in IR injury which can provide insight for the future development of novel therapeutics against reperfusion injury.

Amanda Wahl awarded a three-year NIH F31 Ruth L. Kirschstein Predoctoral Individual National Research Service Award

Monday, February 1, 2021

Congratulations to Amanda Wahl, graduate student in the CMPP program, laboratory of Dr. David Yule. Amanda was recently awarded a three-year NIH F31 Ruth L. Kirschstein Predoctoral Individual National Research Service Award entitled, "Elucidating the mechanisms of salivary gland dysfunction following gamma-irradiation utilizing an experimental and computational approach".

Project Summary:

Individuals diagnosed with head and neck cancer undergo radiation therapy as a standard treatment. However, in the process of using radiation therapy to shrink the tumor, the salivary glands are inadvertently and irreversibly damaged. This damage manifests as a loss of saliva secretion, occurs rapidly without marked cell death, and leads to deleterious effects, including loss of taste, oral infections, and xerostomia (dry mouth). The mechanism by which this early loss of function occurs, is currently unknown and presently there is little in the form of

treatment, with most options being palliative. Thus, there is a pressing need to expand our understanding of salivary gland physiology and the effects of g-irradiation on both the structure and function of the salivary gland. This proposal utilizes experimental techniques including confocal, Stimulated Emission Depletion (STED) and intravital microscopy. Each technique will be employed for use in a variety of assays to investigate the structural and functional consequences of acute g-irradiation on salivary glands. This in vitro and in vivo experimental

approach will additionally be used in combination with computational modeling through a long-term collaboration to understand in detail the effect of g-irradiation on secretion. In an iterative manner, experimental data will be input to the computation model and subsequently used to make further predictions which will be experimentally tested- furthering our understanding of physiology and pathology of salivary glands. In these studies, this experimental-computational approach will be used to determine how alterations within the salivary gland impact

its function, leading to dry mouth, and an eventual permanent loss of glandular tissue and function. This proposal addresses three different mechanisms that may dictate this loss of function. These include an alteration in functioning of gap and tight junctions, calcium signaling, and mitochondrial bioenergetics. By examining each of these aspects, the experimental data can be integrated into the computational model. The great utility of this approach is that many iterations of computational experiments can be completed in parallel with these in vitro

and in vivo studies and used to suggest further experiments and make predictions. The dynamic utilization of this computational-experimental approach will facilitate understanding how an alteration in a component of the gland's secretory machinery following g-irradiation might alter saliva production. Ultimately, this approach is designed to forecast potential novel therapeutic approaches for treating g-irradiation induced salivary dysfunction.
