Experimental model could be instrumental in testing novel therapies for diseases that now lack treatments WASHINGTON - An off-the-shelf dietary supplement available for pennies per dose demonstrated the ability to reverse cellular damage linked to specific genetic mutations in transgenic fruit flies, an experimental model of genetic mutation-induced renal cell injury that features striking similarities to humans, a Children's National Health System research team reports April 20 in Journal of the American Society of Nephrology. "Transgenic Drosophila that carry mutations in this critical pathway are a clinically relevant model to shed light on the genetic mutations that underlie severe kidney disease in humans, and they could be instrumental for testing novel therapies for rare diseases, such as focal segmental glomerulosclerosis (FSGS), that currently lack treatment options," says Zhe Han, Ph.D., principal investigator and associate professor in the Center for Cancer & Immunology Research at Children's National and senior study author. Nephrotic syndrome (NS) is a cluster of symptoms that signal kidney damage, including excess protein in the urine, low protein levels in blood, swelling and elevated cholesterol. The version of NS that is resistant to steroids is a major cause of end stage renal disease. Of more than 40 genes that cause genetic kidney disease, the research team concentrated on mutations in genes involved in the biosynthesis of Coenzyme Q10 (CoQ10), an important antioxidant that protects the cell against damage from reactive oxygen. "This represents a benchmark for precision medicine," Han adds. "Our gene-replacement approach silenced the fly homolog in the tissue of interest - here, the kidney cells - and provided a human gene to supply the silenced function. When we use a human gene carrying a mutation from a patient for this assay, we can discover precisely how a specific mutation - in many cases only a single amino acid change - might lead to severe disease. We can then use this personalized fly model, carrying a patient-derived mutation, to perform drug testing and screening to find and test potential treatments. This is how I envision using the fruit fly to facilitate precision medicine." Drosophila pericardial nephrocytes perform renal cell functions including filtering of hemolymph (the fly's version of blood), recycling of low molecular weight proteins and sequestration of filtered toxins. Nephrocytes closely resemble, in structure and function, the podocytes of the human kidney. The research team tailor-made a Drosophila model to perform the first systematic in vivo study to assess the roles of CoQ10 pathway genes in renal cell health and kidney function. One by one, they silenced the function of all CoQ genes in nephrocytes. As any individual gene's function was silenced, fruit flies died prematurely. But silencing three specific genes in the pathway associated with NS in humans - Coq2, Coq6 and Coq8 - resulted in abnormal localization of slit diaphragm structures, the most important of the kidney's three filtration layers; collapse of membrane channel networks surrounding the cell; and increased numbers of abnormal mitochondria with deformed inner membrane structure. The flies also experienced a nearly three-fold increase in levels of reactive oxygen, which the study authors say is a sufficient degree of oxidative stress to cause cellular injury and to impair function - especially to the mitochondrial inner membrane. Cells rely on properly functioning mitochondria, the cell's powerhouse, to convert energy from food into a useful form. Impaired mitochondrial structure is linked to pathogenic kidney disease. The research team was able to "rescue" phenotypes caused by silencing the fly CoQ2 gene by providing nephrocytes with a normal human CoQ2 gene, as well as by providing flies with Q10, a readily available dietary supplement. Conversely, a mutant human CoQ2 gene from an patient with FSGS failed to rescue, providing evidence in support of that particular CoQ2 gene mutation causing the FSGS. The finding also indicated that the patient could benefit from Q10 supplementation.

Specific genetic errors that trigger congenital heart disease (CHD) in humans can be reproduced reliably in Drosophila melanogaster - the common fruit fly - an initial step toward personalized therapies for patients in the future. "Studying CHD in fruit flies provides a fast and simple first step in understanding the roles that individual genes play in disease progression," says Zhe Han, Ph.D., a principal investigator and associate professor in the Center for Cancer & Immunology Research at Children's National Health System and senior author of the paper published Jan. 20, 2017 in eLife. "Our research team is the first to describe a high-throughput in vivo validation system to screen candidate disease genes identified from patients. This approach has the potential to facilitate development of precision medicine approaches for CHD and other diseases associated with genetic factors," Han says. Some 134 genes have been implicated in causing CHD, a birth defect that affects 8 in 1,000 newborns, according to the National Institutes of Health. The research team led by Han used high-throughput techniques to alter the activity of dozens of genes in flies' hearts simultaneously in order to validate genes that cause heart disease. "Our team was able to characterize the effect of these specific genetic alterations on heart development, structure and activity," Han adds. "The development of the human heart is a complicated process in which a number of different cell types need to mature and differentiate to create all of the structures in this essential organ. The precise timing of those cellular activities is critical to normal heart development, with disruptions in the structure of proteins called histones linked to later heart problems.". Of 134 genes studied by the research team, 70 caused heart defects in fruit flies, and several of the altered genes are involved in modifying the structure of histones. Quantitative analyses of multiple cardiac phenotypes demonstrated essential structural, functional and developmental roles for these genes, including a subgroup encoding histone H3K4 modifying proteins. The scientists then corroborated their work by reliably reproducing in flies the effect of specific genetic errors identified in humans with CHD. "This may allow researchers to replicate individual cases of CHD, study them closely in the laboratory and fashion treatments personalized to that patient specifically," he adds. "Precise gene-editing techniques could be used to tailor-make flies that express a patient's specific genetic mutation. Treating CHD at the level of DNA offers the potential of interrupting the current cycle of passing along genetic mutations to each successive generation."

Two drugs used to treat asthma and allergies may offer a way to prevent a form of pneumonia that can kill up to 40 percent of people who contract it, researchers at the University of Virginia School of Medicine have found. Influenza pneumonia results when a flu infection spreads to alveolar air sacs deep within the lungs. Normally, a flu infection does not progress that far into the lower respiratory tract, but when it does, the results can be deadly. "If infection is severe enough, and the immune response is potent enough, you get injury to these cells and are no longer able to get sufficient oxygen exchange," explained UVA researcher Thomas J. Braciale, MD, PhD. "As a result of the infection of the cells, you can develop lethal pneumonia and die." But early administration of the two asthma drugs, Accolate and Singulair, could prevent the infection of the alveolar cells deep in the lower respiratory tract, Braciale's research suggests. "The excitement of this is the possibility of someone coming to see the physician with influenza that looks a little more severe than usual and treating them with the drugs Singulair or Accolate and preventing them from getting severe pneumonia," he said. "The fatality rate from influenza pneumonia can be pretty high, even with all modern techniques to support these patients. Up to 40 percent. So it's a very serious problem when it occurs." Unlike bacterial pneumonia, influenza pneumonia is caused by a virus. That makes it very difficult to treat - and makes the possibility of prevention all the more tantalizing. "When we look at pandemic strains of influenza that have high mortality rates, one of the best adaptations of those pandemic viruses is their ability to infect these alveolar epithelial cells," explained researcher Amber Cardani, PhD. "It's one of the hallmarks for certain strains that cause the lethality in these pandemics." Once influenza spreads deep into the lungs, the body's own immune response can prove harmful, resulting in severe damage to the alveolar air sacs. "It's an important observation the field is coming to," Cardani said. "We really need to limit the infection of these lower respiratory airways." The researchers determined that the alveolar epithelial cells are typically protected from influenza infection by immune cells called alveolar macrophages. In some instances, however, the flu virus can prevent the macrophages from carrying out their protective function, allowing the epithelial cells to become vulnerable to infection. "It's not as though they lack alveolar macrophages, it's just that their alveolar macrophages don't work right when they get exposed to the flu," Braciale said. "And those are the types of patients, who potentially would eventually go to the intensive care unit, that we think could be treated early in infection with Accolate or Singulair to prevent infection of these epithelial cells and prevent lethal infection." For their next steps, the researchers are consulting with colleagues to determine if patients being treated with Accolate and Singulair are less likely to develop influenza pneumonia during flu outbreaks. "This was a totally unexpected observation," Braciale said. "When I told multiple colleagues who are infectious disease or pulmonary physicians, they were absolutely flabbergasted." The findings have been published by the scientific journal PLOS Pathogens. It was written by Cardani, Adam Boulton, Taeg S. Kim and Braciale. Braciale and Cardani are both part of UVA's Department of Microbiology, Immunology and Cancer Biology and UVA's Beirne B. Carter Center for Immunology Research. Braciale's primary appointment is with the Department of Pathology. The work was supported by the National Institutes of Health, grant R01AI015608-35, and the NIH's National Institute of General Medical Sciences, grants T32 GM007055 and T32 GM007055.

WASHINGTON, DC - A Children's National Health System research team has uncovered a novel process by which the gene APOL1 contributes to renal disease, according to a paper published November 18 in the Journal of the American Society of Nephrology. Mutated versions of the APOL1 gene render people of African descent at heightened risk of developing chronic kidney disease. Employing powerful genetic approaches, Children's National researchers were able to mimic APOL1 renal cell pathology in the fruit fly Drosophila melanogaster. This opens the door to pinpointing other proteins that interact with APOL1, a vital first step toward identifying medicines to treat renal diseases that currently have no drug therapy. "This is one of the hottest research topics in the kidney field. We are the first group to generate this result in fruit flies," says Zhe Han, PhD, a senior Drosophila specialist and associate professor in the Center for Cancer & Immunology Research at Children's. Han, senior author of the paper, will present the study results this week during Kidney Week 2016, the American Society of Nephrology's annual gathering in Chicago that is expected to draw more than 13,000 kidney professionals from around the world. The advantages of Drosophila for biomedical research include its rapid generation time and an unparalleled wealth of sophisticated genetic tools to probe deeply into fundamental biological processes underlying human diseases. People of African descent frequently inherit a mutant version of the APOL1 gene that affords protection from African sleeping sickness, but is associated with a 17- to 30-fold greater chance of developing certain types of kidney disease. That risk is even higher for individuals infected with the human immunodeficiency virus (HIV). Drosophila renal cells, called nephrocytes, accurately mimic pathological features of human kidney cells during APOL1-associated renal disease. "Nephrocytes share striking structural and functional similarities with mammalian podocytes and renal proximal tubule cells, and therefore provide us a simple model system for kidney diseases," says Han, who has studied the fruit fly for 20 years and established the fly nephrocyte as a glomerular kidney disease model in 2013 with two research papers in the Journal of the American Society of Nephrology. In this most recent study, Han's team cloned a mutated APOL1 gene from podocyte cells cultured from a patient with HIV-associated nephropathy. They created transgenic flies making human APOL1 in nephrocytes and observed that initially the transgene caused increased cellular functional activity. As flies aged, however, APOL1 led to reduced cellular function, increased cell size, abnormal vesicle acidification, and accelerated cell death. "The main functions of nephrocytes are to filter proteins and remove toxins from the fly's blood, to reabsorb protein components, and to sequester harmful toxins. It was surprising to see that these cells first became more active and temporarily functioned at higher levels," says Han. "The cells got bigger and stronger but, ultimately, could not sustain that enhancement. After swelling to almost twice their normal size, the cells died. Hypertrophy is the way that the human heart responds to stress overload. We think kidney cells may use the same coping mechanism." The Children's research team is a multidisciplinary group with members from the Center for Cancer & Immunology Research, the Center for Genetic Medicine Research, and the Division of Nephrology.The team also characterized fly phenotypes associated with APOL1 expression that will facilitate the design and execution of powerful Drosophila genetic screening approaches to identify proteins that interact with APOL1 and contribute to disease mechanisms. Such proteins represent potential therapeutic targets. Currently, transplantation is the only option for patients with kidney disease linked to APOL1. "This is only the beginning," Han says. "Now, we have an ideal pre-clinical model. We plan to start testing off-the-shelf therapeutic compounds, for example different kinase inhibitors, to determine whether they block any of the steps leading to renal cell disease."

PURPOSE OF REVIEW: This review describes the challenges created by the existence of multiple molecular pathways leading to fibrosis and proposes that attention be focused on targeting the fibroblasts and myofibroblasts which themselves produce multiple cytokines and growth factors as well as the extracellular matrix, which is the hallmark of fibrotic lung disease. RECENT FINDINGS: The last 20 years have seen remarkable progress in our understanding of the molecular pathogenesis of pulmonary fibrosis leading to multiple programmes in drug discovery, and there are currently 15 actively recruiting trials registered on http://www.clinicaltrials.gov. Unfortunately, at this time only one new drug, pirfenidone, has progressed to approval for use in patients. Part of the frustration is that drugs that are effective in targeting inflammatory pathways have been ineffective in lung fibrosis. This may result from the inability to treat patients early in the disease process but it is also likely that pathways independent of inflammation can drive fibrosis. SUMMARY: We further propose that this approach should inhibit fibrosis independent of cell type or the signalling cascade that is activating these cells. We are hopeful that the next 20 years will see many more therapeutic options for patients suffering with fibrotic lung disease. Copyright © 2012 Lippincott Williams & Wilkins.

Expert Opinion on Biological Therapy | Year: 2010

Importance of the field: DNA vaccination for transplantation has been less investigated compared with DNA vaccines for infectious disease, cancer and pathological autoimmunity. However, the emerging role of transplant-induced autoimmunity in allograft rejection may lead to the development of new DNA vaccination approaches where peripheral delivery of an antigen shared by recipient and allograft could be used to prevent rejection of a given organ for large numbers of individuals. In addition, apoptosis-inducing DNA vaccines could further minimize the need to identify specific donor antigens for induction of tolerance by generating apoptotic cells carrying donor or recipient antigens depending on site of vaccine delivery. Area covered in this review: The review covers DNA vaccination approaches that have been taken to prolong allograft survival in different animal model systems and their possible immune mechanisms and speculates on the future role of DNA vaccines for transplantation. What the reader will gain: The review gives insight into how new DNA vaccination strategies might be developed to take into account recent development in allotransplantation. Take home message: DNA vaccination could reduce the need for systemic immunosuppressants and be applied to prevention of chronic rejection, which remains a major barrier to successful allotransplantation. © 2010 Informa UK Ltd.
