What is the effect of variant genes on AVM development in HHT

Natural genetic variation between individuals can influence the outcome of carrying an HHT mutation. Some gene variants may be protective while others may increase the risk of AVM or telangiectasis. By identifying the variant genes that alter risk of AVM may give clues to the molecular mechanisms of AVM formation and provide new drug targets

Goal 3: Advance Translational Research

Developing Curative Approaches to Cardiovascular Disease rather than Chronic Magement

Most Pharmacological interventions in cardiovascular diseases tend to address to be used in palliative manner and chronically. There is urgent need for treatments that are curative. This goes to identifying molecular drivers of the diseases and targeting them to correct the underlying pathophysiology rather than symptom suppression.

Goal 3: Advance Translational Research

Calcium channels in cardiovascular functions and diseases

Fifty years ago Prof. Harald Reuter of the University of Bern, Switzerland obtained the first experimentally supported evidence that the calcium channel is a physiologically distinct entity. Further stimulated by the synthesis of the dihydropyridine calcium channel blocker nifedipine, the field of calcium channel research rapidly encompassed cardiovascular and other powerful biomedical directions.

Goal 2: Reduce Human Disease

what are the molecular pheontypic differences in IPF/ILD

What are the molecular phenotypic differences in blood and tissue of IPF ILD and how do they relate to disease course and potential response to therapy. There is a need to gain understanding in humans of the differences and similarities in iPF and iLD in general to eliminate the idiopathic nature and establish human targets. The challenge is coupling such research to longer term studies/outcomes and potentially clinical ...more »

Details on the impact of addressing this CQ or CC :

Establishing molecular definitions for this idiopathic disease would a) provide greater clarity and definition to a what is otherwise a syndrome b) establish targets for intervention both for IPF and ILD in general c) refocus translational efforts on human setting for this purely human disease d) establish molecular relationships between IPF and outcomes e) establish intermediate biomarkers for more rapid evaluation for treatment development f) allow potential crossover development with acute lung injury fibrosis g) establish molecular relationships for crossover with human immunology studies and other autoimmune diseases with fibrotic tissue development (CAD, Glomerulonephritis, etc).

Feasibility and challenges of addressing this CQ or CC :

Challenges surround lack of a larger more comprehensive and integrative approach to studying human disease. In an uncommon disease such as IPF, mutlicenter patient enrollment and biologics acquisition must occur in conjunction with both long term longitudinal outcomes and the influence of both new standard of care therapies and novel clinical trials. The scope of studies must be larger, more pragmatic and longer than previously designed NIH clinical studies to allow for integration of translational research. The challenge surrounds failure to allow these elements to coexist. The potential very large for true ILD program with a vision for a long term integrative plan with vision rather than just individual RO1 efforts. An example would an overriding longitudinal study in which patients could enroll and participate in other projects/studies/treatment but where the patient is never lost to follow up. This as cornerstone would then allow other programatic efforts to coexist.

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Critical Challenge (CC)

Details on the impact of addressing this CQ or CC :

As targeted therapy and molecular mechanisms of disease are emerging, a mechanism to improve the ability of radiologists to perform translational research is crucial. Such knowledge is essential for collaborative multidisciplinary research that ultimately leads to imaging as disease-specific diagnostic and therapeutic tools to combat pulmonary and cardiovascular disease.

Feasibility and challenges of addressing this CQ or CC :

Knowledge in the molecular mechanisms of disease and the potential for imaging technology to advance via targeted imaging agents, positron emission tomography (PET), functional MR methods, PET/computer tomography, and PET/MR is increasing. The radiologist has in depth expertise within imaging technology, performance of studies, and diagnostic abilities of imaging techniques. A program directed towards developing imagers towards translational imaging research will include in-depth education and training in lung physiology, pulmonary disease mechanisms, multimodality imaging bridging CT, PET/CT, MR and PET/MR, and the molecular techniques. With such knowledge and training, radiologists will be prepared to serve as principal investigators and collaborators in multidisciplinary teams. An understanding of imaging technologies and their capabilities, the clinical challenges, and molecular techniques will enable imagers to provide innovative solutions to diagnostic dilemmas in pulmonary and cardiovascular disease.

Details on the impact of addressing this CQ or CC :

Phenotypical characterization of cardiovascular disease with computed tomography (CT) and magnetic resonance imaging (MR) to individualize targeted therapies for coronary artery and myocardial disease. Coronary artery disease is a major cause of patient death in the United States. Nonischemic myocardial disease includes entities with clinically heterogeneous presentations and is thus challenging to manage.

Feasibility and challenges of addressing this CQ or CC :

Currently CT and MR technology allows dynamic evaluation of the perfusion and contractility of the heart. Quantitative measures of disease burden, such as atherosclerotic plaque composition and myocardial texture imaging biomarkers (such as T1 mapping, activation mapping, flow pattern analysis, delayed myocardial enhancement), are possible. Positron emission tomography (PET)/MR, which combines metabolic with functional evaluation, is currently available and facilitates the development of targeted molecular-imaging techniques. Metrics derived from these techniques may serve to stratify patients noninvasively and direct appropriate therapies. Such imaging methods address noninvasive evaluation of cardiovascular disease, including ischemic heart disease but also myocardial diseases that include secondary and infiltrative cardiomyopathies, hypertrophic cardiomyopathy, and organ rejection in the scenario of transplantation.

Quantitative imaging biomarkers for chronic lung disease

Critical Challenge

Submitted by (@str0001)

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Critical Challenge (CC)

Details on the impact of addressing this CQ or CC :

Methods for stratifying patients with diffuse lung disease are crucial for predicting their clinical course and directing appropriate therapies accordingly. Currently imaging markers for prognostic stratification are limited, due to observer variability in characterizing the type and degree of computed tomography (CT) abnormalities. A reproducible method for categorizing varying diffuse lung diseases on CT imaging is needed, particularly in combination with other biomarkers in a multidisciplinary approach. With lung cancer screening, the characterization and stratification of patients with varying COPD phenotypes and interstitial lung disease are essential to aid in management of the large number of patients who currently satisfy criteria for CT lung cancer screening.

Feasibility and challenges of addressing this CQ or CC :

Currently the classification of diffuse lung disease on CT is based upon visual evaluation and qualitative or semi-quantitative evaluation of CT data. Diffuse lung disease manifests with varying CT findings and distribution within the lung. Computer-assisted tools for quantifying airways and parenchymal disease have been developed. More-sophisticated quantitative computer image-analysis methods, such as those that address three-dimensional spatial orientation, are possible given advances in computer capabilities yet remain in need of further development. Advances in magnetic resonance imaging (MR) technology, positron emission tomography (PET), and PET/MR will increase the ability to characterize diffuse lung disease quantitatively. The ability of such technology to differentiate subtypes within more frequently occurring and clinically-significant diffuse lung disease is feasible. Such tools would impact a large population, particularly given the potential need to phenotype emphysema and smoking-related interstitial pneumonias in those undergoing CT screening.

UNDERSTANDING SLEEP AND CIRCADIAN DISORDERS AT A BASIC MECHANISTIC LEVEL

We need to understand sleep and circadian disorders at a more mechanistic level. This applies to both the pathogenesis of these disorders and to their impact on health.

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Critical Challenge (CC)

Details on the impact of addressing this CQ or CC :

Much of the research on the consequences of sleep/circadian disorders has focused on their consequences or behavior. This type of research needs to be continued and there are new opportunities in this area. These behavioral studies need to be established in model systems to parallel studies in humans. In addition, new neurobiological approaches, including optogenetics and use of DREAD, provide new tools for this investigation. Moreover, we now have powerful molecular tools to evaluate effects of sleep/circadian disorders both in humans and animal models. These include microarrays, RNA seq, etc. Moreover, genetic studies, e.g., in restless legs syndrome, have identified gene variants conferring risk for the disorder. We do not know, however, how these particular genes are involved in the pathogenesis of the disorder or whether they represent potentially targets for drug intervention. There is a need for studies both in animal models and in humans to elucidate the function of these genes. Studies in other areas are obtaining stem cells from biopsies in patients and then turning these into relevant target cells such as neurons to elucidate gene function using in vitro approaches.

The impact of this effort will be the following:

 

a. Taking our understanding of pathogenesis of sleep and circadian disorders to a new level.

b. Understanding the consequences of sleep and circadian disorders on different end organs at a more in-depth molecular level.

Feasibility and challenges of addressing this CQ or CC :

The sleep and circadian field have access to all the major cells systems for these studies—C. elegans, aplysia, Drosophila, zebra-fish, mice, etc. Moreover, there are already gene variants identified in human studies which require follow-up functional studies. The field has the expertise in all of the techniques described above. Moreover, there are more validated animal models for many of the common sleep disorders. Thus, this new approach is very feasible.

Developing clinically viable methods to detect rupture prone aneurysms can lead to better methods of diagnosis and intervention and avoid preventable fatalities

Feasibility and challenges of addressing this CQ or CC :

Several other disease areas including oncological that had similar gap was filled by NIH (NCI) and the challenges were overcome in less than 10 years. The scientific expertise to fill the gap exists, however they work in silos, which need to be brought together to fulfil this gap and is achievable in less than 10 years

Assessment of aortic aneurysms that are prone to rupture or dissection has been an elusive target. Current clinical practice measures the aortic diameter and fails to relate to the pathophysiology and biomechanical properties of the aneurysm in deciding preventive surgery. Critical gap exists in the diagnosis of aneurysm especially with small aneurysms (3 - 5 cm in diameter) that are rupture prone. Based on autopsy about 10 percent of individuals with small abdominal aneurysms had undergone fatal rupture, while 40 percent with diameters of 7-10 cm had intact aneurysm and died from other causes. International Registry of Aortic Dissection found that 40% of thoracic aneurysms dissected at diameters smaller than 5 cm.
