The Bioenergetics Consequences of Winter Cold in Small Birds
Dr. Andreas Nord, researcher in evolutionary ecology at Lund University, Sweden, will present his study on "The Bioenergetics Consequences of Winter Cold in Small Birds".
Dr. Nord highlighted: "Small birds at high latitude face converging energetic challenges in winter, when low air temperature increases the energy cost of staying warm at the same time as short day length and snow constrain refuelling opportunities. The thermoregulatory adaptations that permit existence in such environments are well studied on organismal levels, but analogous processes in the cellular machinery fuelling thermoregulation are poorly understood. In this talk, I will outline how seasonal and diurnal changes in mitochondrial function interact with whole-animal physiology to help birds stay warm when it is cold".

Exercise-Induced, Mitochondrial-Mediated Cell Death in Arrhythmogenic Cardiomyopathy
Dr. Stephen Chelko from Department of Biomedical Sciences, Florida State University, USA will join the Targeting Mitochondria 2021 Congress which will be held on October 27-29, 2021 and will give a presentation on his recent work in Science Translational Medicine on the "Exercise-Induced, Mitochondrial-Mediated Cell Death in Arrhythmogenic Cardiomyopathy".
Arrhythmogenic Cardiomyopathy (ACM) is a familial heart disease with a high incidence of sudden cardiac death in the young and in athletes. Reduced penetrance and variable expressivity complicate early diagnosis and management of ACM. More and more evidence on the deleterious impact of exercise in ACM is growing, yet these studies all implicate the arrhythmic risk and/or hemodynamic load on the heart in response to exercise. New evidence demonstrates that endurance exercise leads to mitochondrial dysfunction, ROS generation, and large-scale myocyte death in ACM.

Mitochondrial DNA in Cancer: The Overlooked Oncogenome
Dr. Payam A. Gammage from CRUK Beatson Institute, United Kingdom will join the Targeting Mitochondria 2021 Congress and will present a talk entitled "Mitochondrial DNA in Cancer: The Overlooked Oncogenome" during the congress.
Dr. Gammage will discuss the mutations of mtDNA that have been detected in human cancers for some decades, although their impact on the disease has not been clear and any potential role of mitochondrial genetics in cancer has been broadly overlooked. To better understand the role of mtDNA in cancer we repurposed targeted clinical sequencing data to assemble the largest dataset of partially matched tumour-normal mtDNA sequences to date (>40,000 tumours). Using this resource he has, Dr. Gammage defined the pan cancer landscape of mtDNA mutations, demonstrating clear evidence of respiratory complex-specific mutational recurrence and selection alongside the impact of mtDNA mutations on patient survival.

Patient-Specific Brain Organoids for Modeling Mitochondrial Diseases
Prof. Alessandro Prigione from, Heinrich Heine University (HHU), Germany will talk about "Patient-Specific Brain Organoids for Modeling Mitochondrial Diseases" during the congress which will be held on October 27-29, 2021 in Berlin & Online.
Mitochondrial diseases suffer from a lack of effective animal and cellular models. This hampers our understanding of the mechanisms underlying the neuronal pathology characteristics of mitochondrial diseases. Prof. Prigione used patient-derived induced pluripotent stem cells (iPSCs) and genome engineering with CRISPR/Cas9 to develop a human model of Leigh syndrome, which is the most severe mitochondrial disease in children and is currently incurable. Using neuronal cell cultures and three-dimensional brain organoids, he discovered previously unknown mechanisms causing the disease-specific neuronal defects, and identified two potential counteracting strategies for this rare mitochondrial disease with highly unmet medical need.

Welcome to Targeting Mitochondria 2021
On behalf of the Scientific Committee of the World Mitochondria Society (WMS) we are excited to announce that the 12th Conference on Targeting Mitochondria for October 27-29, 2021 will be held as an Interactive Online Congress with live slots where many discussions and networking will unite all speakers, presenters and attendees.
On this occasion I would like to state frankly that the success of our virtual congress exceeded my expectations. From the numerous feedbacks we have received I can conclude that COVID-19 was unable to diminish our enthusiasm for the cell organelle we all revere so much. Even more, the special online format we chose seemed to have provided some unexpected benefits. For example, there was no Session Chair who had to enforce any schedule, which allowed for more extensive discussion sections as appreciated by many of us. Further, the availability of all conference contributions for an extended period of time was certainly also a very valuable feature of our 11th conference. Nevertheless, one of the most important aspects of any scientific meeting was missing, which is the personal interaction with colleagues from around the world, be it in the lecture hall, or during the coffee break or last but not least during our conference dinner. Therefore we all are very much looking forward to the next, the 12th edition of our conference series.
Independent on its format, any conference can only be as good as its speakers and its organizers. Knowing that the Organizing Committee under Prof. Marvin Edeas’ leadership will again excel in setting up the next conference, and knowing that the Scientific Committee will again invite key players in the field of Mitochondrial Medicine I assure anyone who is going to join us in this year's Interactive Online Congress on October 2021 that you won’t be disappointed, excellent interactive platform, again excellent speakers and again an excellent organization!
While we have just started working on the outline of our next conference edition, I believe that the overarching themes of our 12th World Congress on Targeting Mitochondria will not significantly deviate from topics discussed at preceding editions of our conference series. Again, we will focus on three major areas, which are first the role of mitochondrial dysfunction in etiology and pathogenesis of chronic diseases including aging, second how to assess and above all quantify mitochondrial dysfunction in vitro and in vivo and finally, third, how to target and manipulate mitochondrial function in order to develop future mitochondria-based therapies. However, we will also try to further extend the profile and scope of our conference by inviting researchers who have never participated in our meeting before, established and new investigators alike.
Basic scientists working at the bench in the laboratory, physicians treating patients suffering from mitochondrial disorders as well as representatives of companies working on the commercialization of mitochondria-targeted therapies are all welcome to our conference. We strongly believe that our 12th World Congress on Targeting Mitochondria will be at least as exciting and as successful as our virtual 11th conference. Please feel free to contact us at any time for further information and with questions you might have.
All our warmest regards.

Mitochondria Devices: New Methods to Detect Mitochondria Dysfunction
Dr. Naïg Gueguen from MitoVasc Institute, Angers University Hospital Center, France will give a presentation entitled "Mitochondria Devices: New Methods to Detect Mitochondria Dysfunction" during the Targeting Mitochondria 2020 Congress which will be organized virtually, on October 29-30, 2020.
Summary of the presentation: Alterations in bioenergetics metabolism represent a common clue in the pathogenesis of several diseases, including metabolic disorders, neurodegenerative disease, inflammatory conditions and cancer. Progress toward deciphering the precise role of the mitochondria in disease etiology requires tools and methods that can dissect the complex interplay between multiple enzymes and oxidative pathways that act cooperatively to regenerate ATP and sustain cellular biosynthesis needs. Recent developments in respirometry, coupled to fluorometry/luminescence, allow multiplexing measurements and provide now routine analyses of a variety of processes, including metabolic rewiring, substrate supply pathways, the activities of the different respiratory chain complexes, ATP synthesis or proton leak. In this context, the choice of the relevant experimental model and design are key elements for the identification and quantification of mitochondrial dysfunctions.

The Cell-free respiratory Competent Mitochondria in Blood: Strategic Role and Application
Prof. Alain Thierry from Montpellier Cancer Research Institute, INSERM, France will join the Targeting Mitochondria 2020 Congress which will be organized virtually and give a major presentation entitled "The Cell-free respiratory Competent Mitochondria in Blood: Strategic Role and Application".
The researchers used previous findings which showed that the plasma of a healthy individual contains up to 50,000 times more mitochondrial DNA than nuclear DNA. They hypothesized that for it to be detectable and quantifiable in the blood in this manner, the mitochondrial DNA had to be protected by a structure of sufficient stability. In order to identify such a structure, plasma samples from around 100 individuals were analyzed.
This analysis revealed the presence in the blood circulation of highly stable structures containing whole mitochondrial genomes. Following examination of their size and density, as well as the integrity of their mitochondrial DNA, these structures observed using electron microscopy (up to 3.7 million per ml of plasma) were revealed to be intact and functional mitochondria.

Mitochondrial disease community registry (MDCR): Perspectives from patients and families, lessons learned from the data
Mrs. Sophia Zilber from Boston, USA will join the Targeting Mitchondria 2020 Congress and will give a presentation entitled "Mitochondrial disease community registry (MDCR): Perspectives from patients and families, lessons learned from the data".
Patient-populated registries are an important component of rare disease communities for many reasons, including their use as a tool for gathering opinions on specific topics. The Mitochondrial Disease Community Registry (MDCR) was launched in 2014 by United Mitochondrial Disease Foundation (UMDF) for this purpose as well as to identify and characterize mitochondrial disease patients from the patient perspective. This talk presents data collected over a four year period and provided by adult mitochondrial disease patients and caregivers of pediatric mitochondrial disease patients. Findings suggest the importance of clinician-patient communication, need for treatment and cure, the impact of the disease on the entire life of a person, and quality of life as top issues as described by patients, while also highlighting that patients are hopeful and optimistic. Additionally, data quality checks showed that more clear and simple questions and shorter more-targeted surveys are needed in order to get accurate and meaningful data for research.

Down Syndrome: Role of hydrogen sulfide overproduction in the pathogenesis of mitochondrial dysfunction
The Organizing Committee of Targeting Mitochondria 2020 honored to welcome Prof. Csaba Szabo from the Université de Fribourg, Switzerland.
Prof. Szabo will give a talk entitled "Down Syndrome: Role of hydrogen sulfide overproduction in the pathogenesis of mitochondrial dysfunction" during the congress which will be held on October 29-30, 2020 in Berlin, Germany.
Summary of the talk: Cystathionine-β-synthase (CBS) is one of the key mammalian enzymes that is responsible for the biological production of the gaseous transmitter hydrogen sulfide (H2S). When H2S is overproduced, it can exert detrimental cellular effects, in part due to inhibition of mitochondrial Complex IV activity. An increased expression of CBS and the consequent overproduction of H2S is well documented in individuals with Down syndrome (DS). Two decades ago, it has been proposed that a toxic overproduction of H2S importantly contributes to the metabolic and neurological deficits associated with DS. However, until recently, this hypothesis has not yet been tested experimentally. The present talk will present recent data generated in human dermal fibroblasts showing that DS cells overproduce H2S, which, in turn, suppresses mitochondrial Complex IV activity and impairs mitochondrial oxygen consumption and ATP generation. Therapeutic CBS inhibition lifts the tonic (and reversible) suppression of Complex IV: this results in the improvement of mitochondrial function in DS cells.

Mitochondrial Dysfunction in Autism is Distinct from Mitochondrial Disease
The Organizing Committee of Targeting Mitochondria 2020 is honored to announce the participation of Prof. Richard E. Frye from Phoenix Children's Hospital, USA.
During the congress, Prof. Frye will give a strategic talk entitled "Mitochondrial Dysfunction in Autism is Distinct from Mitochondrial Disease".
Summary of the talk: Several lines of evidence suggest that mitochondrial function is not normal in many individuals with Autism Spectrum Disorder. However, the patterns of abnormalities found are unlike those seen in classic mitochondrial disease and include unique changes in electron transport chain activity, fatty acid metabolism and regulation of oxidative stress. This talk presents data that suggest that these unique abnormalities are a product of long-term metaplasticity adaptations resulting from exposure to extrinsic or intrinsic physiological stressors such as environmental exposures, microbiome alterations, nutrient deficiencies and/or inflammatory events.

Roles for mitochondrial dysfunction in Alzheimer’s disease
The Scientific Committee of Targeting Mitochondria 2020 Congress invited Prof. Benedict C. Albensi from Max Rady College of Medicine - University of Manitoba, Canada to present his research on "Roles for mitochondrial dysfunction in Alzheimer’s disease" during the Targeting Mitochondria 2020 Congress, which will be held on October 29-30, 2020.
According to Prof. Benedict C. Albensi: Alzheimer’s disease (AD) is thought to be associated with multiple factors, where the greatest risk factor for AD is aging. In addition, much research has focused on amyloid beta and tau pathology as causative factors in AD. However, new data involving brain metabolic activity, proposes that altered mitochondria are a major force behind the development of AD. Understanding mitochondrial dysfunction and targeting mitochondrial bioenergetics could be a novel treatment approach holding great promise for preventing or treating AD.
