Winner of the Best Mitochondria Image 2022: Erminia Donnarumma, Institut Pasteur
The World Mitochondria Society congratulates the winner of the Best Mitochondria Image 2022 Erminia Donnarumma, Institut Pasteur, France. Her image entitled "Mitochondria run parallel in mature cardiomyocytes" shows: Adult primary cardiomyocytes (mouse) stained with TMRE (mitochondria, orange) and NucBlue (nuclei, blue).
Dr. Donnarumma performed her PhD (2012-2015) in Pharmaceutical Sciences between the University of Naples Federico II in Italy and the Cardiovascular Center of Excellence in New Orleans (USA). Her work focused on the identification of new medications that could act or improve the crosstalk between the hydrogen sulfide (H2S) and nitric oxide (NO) signaling in small and large animal models of heart failure induced by myocardial ischemia and reperfusion injury. After this time, she nucleated my interest in mitochondria as therapeutic target in cardiac diseases. She therefore moved to France in 2016 to join the Wai Lab at the Institut Pasteur.
Dr. Donnarumma stated: "The main focus of my work was to investigate the role of Mitochondrial Fission Process 1 (MTFP1) in mitochondrial dynamics and the heart homeostasis. I discovered that MTFP1 loss in cardiomyocytes impairs mitochondrial inner membrane integrity leading to impaired mitochondrial bioenergetics, cardiomyocyte death and inflammatory dilated cardiomyopathy. My on-going and future researches aim at the understanding how mitochondria trigger inflammation in cardiomyocytes and the relevance of the sex bias that exists at the level of mitochondria for the development of sex- specific cardiac diseases".

Personalized Medicine in Mitochondrial Health and Disease: Myth and Reality
Prof. Ciro Leonardo Pierri from the University of Bari, Italy, will join the 14th edition of the World Conference on Targeting Mitochondria 2023, held in Berlin, Germany, from October 11th to 13th. In this conference, Prof. Pierri will give a talk entitled "Personalized Medicine in Mitochondrial Health and Disease: Myth and Reality.
Mitochondrial diseases may result from mutations affecting nuclear or mitochondrial genes, encoding mitochondrial proteins, or non-protein coding mitochondrial RNA. Despite the great variability of affected genes, in the most severe cases, a neuromuscular degenerative phenotype is observed, and no specific therapy exists for a complete recovery from the disease.
The most used treatments are symptomatic based on the administration of antioxidant cocktails in combination with antiepileptic/antipsychotic drugs. Unfortunately, antioxidant therapies have met limited success and it is still urgent to highlight new/real pharmacological targets and to design/identify highly selective/efficient drugs to rescue mitochondrial-impaired pathways. In this context, very little attention was dedicated to proteins responsible for the crosstalk between mitochondria and cytoplasm such as mitochondrial transporters (i.e., SLC25A family members) and FAD/NADH dehydrogenases (i.e., AIF), playing a crucial role in the maintenance of metabolites and oxidative balance, as well as in the regulation of mitochondrial apoptosis.
Prof. Pierri will discuss molecular aspects of the limited success of antioxidant therapies, and will illustrate the role of mitochondrial transporters and FAD/NADH dehydrogenases in mitochondrial function for the possible development of new MD treatments.

The role of Mitochondria in Liver Regeneration
Prof. Jiri Neuzil from Griffith University, Australia will join the Targeting Mitochondria 2023 congress which will be held on October 11-13, 2023 in Berlin, Germany, and will present a talk entitled "The role of Mitochondria in Liver Regeneration".
Prof. Neuzil focuses on the role of mitochondria in cancer. Major projects of his laboratory are mitochondria as a target for cancer therapy; horizontal transfer of mitochondria; the role of respiratory complexes in the biology and function of mitochondria; role of metabolic switch in malignant transformation and tissue regeneration. He developed a novel anti-cancer drug, mitochondrially targeted tamoxifen (MitoTam), an analogue of tamoxifen tagged with a delocalized cation (triphenylphosphonium) that preferentially targets the inner mitochondrial membrane of cancer cells, interfering with mitochondrial respiratory complex I. MitoTam has recently underwent Phase I/Ib clinical trial with efficacy against renal cell carcinoma.
Prof. Neuzil obtained his Ph.D. from the Institute of Microbiology in Prague, then he was a post-doctoral fellow at the Heart Research Institute in Sydney, Australia. After 3 years at the University of Munich as a Junior Group Leader and one year as a visiting researcher at the University of Linkoping (Sweden), he got the position of Senior lecturer in 2002 (later on Associate Professor and Professor) at Griffith University in Southport, Qld, Australia. Since 2006, he is a Group Leader at the Institute of Biotechnology, Czech Academy of Sciences in Prague. He has published over 245 scientific papers and his HI is 62.

Restoration of Mitochondrial Homeostasis provides Glaucoma Neuroprotection
Prof
. Arupratan Das from Indiana University School of Medicine, USA will join the Targeting Mitochondria 2023 congress and present his study on "Restoration of Mitochondrial Homeostasis provides Glaucoma Neuroprotection".
Neurons are highly energy-demanding due to their constant need for neurotransmission and synaptic activity. Mitochondria are the primary source for cellular energy currency adenosine triphosphate (ATP), and dysfunctional mitochondria present a key pathological condition for the central nervous system (CNS) disorders such as glaucoma, amyotrophic lateral sclerosis (ALS) and Parkinson’s disease. Retinal ganglion cells (RGCs) of the optic nerve are particularly vulnerable to mitochondrial dysfunctions as they need steady supply of ATP for varying frequency of action potential firing through the long unmyelinated axons. Here, using human stem cell differentiated retinal ganglion cells (hRGCs) we have shown hRGCs are efficient in degrading damaged mitochondria and producing simultaneously healthy organelle for maintaining mitochondrial homeostasis.
However, a glaucomatous Optineurin mutant (E50K) hRGCs show high ATP production rate with fewer mitochondrion compared to the wild-type neurons causing mitochondrial swelling and disruption of homeostasis. Remarkably, enhancing mitochondrial biogenesis through pharmacological inhibition of the Tank binding kinase 1 (TBK1) restores energy homeostasis, mitigates mitochondrial swelling with neuroprotection against acute mitochondrial damage for glaucomatous hRGCs, revealing a novel neuroprotection mechanism.

Defining the Molecular Nature of the Mitochondrial permeability transition pore(s)
Prof. Paolo Bernardi from the University of Padova, Italy, will join the 14th edition of the World Conference on Targeting Mitochondria 2023 which will be held from October 11th to 13th in Berlin, Germany, and give a talk entitled "Defining the Molecular Nature of the Mitochondrial permeability transition pore(s)".
Major progress has been made in defining the basis of the mitochondrial permeability transition, a Ca2+-dependent permeability increase of the inner membrane that has puzzled mitochondrial research for almost 70 years. Initially considered an artifact of limited biological interest by most, over the years the permeability transition has raised to the status of regulator of mitochondrial ion homeostasis and of druggable effector mechanism of cell death. The permeability transition is mediated by the opening of channel(s) modulated by matrix cyclophilin D, the permeability transition pore(s) (PTP). The field has received a new impulse from the hypothesis that the PTP may originate from a Ca2+-dependent conformational change of F-ATP synthase and from the reevaluation of the long-standing hypothesis that it originates from the adenine nucleotide translocator. Prof. Bernardi will discuss potential mechanisms for PTP formation and the role of the permeability transition in pathophysiology.

Cardiac MitoMed: From Bench to Bedside
Dr. Sang-Bing Ong from The Chinese University of Hong Kong, China, will join the Targeting Mitochondria 2023 Congress and give a presentation entitled "Cardiac MitoMed: From Bench to Bedside".
Cardiovascular disorders remain the leading cause of death and disability worldwide. The extent of cardiac cell death and left ventricular systolic function are the strongest predictors of morbidity and mortality following cardiac disorders. Despite optimal therapy, the morbidity and mortality of cardiovascular patients remain significantly high. On this background, there remains an urgent clinical need to discover novel therapies for reducing cardiac injury/death and preserving cardiac function so as to improve health outcomes for cardiovascular patients.
In this regard, the viability of the heart and cardiac function is critically dependent on the ability of cardiac mitochondria to generate the energy required for optimal contractile function. Therefore, preventing mitochondrial dysfunction induced by cardiac disorders constitutes an important therapeutic strategy for preserving cardiac viability and function. As opposed to the conventional belief that the mitochondria are static organelles, mitochondria are actually dynamic whereby they change shapes (morphology) and shift locations in the cell. Studies from the last decade have focused on targeting the mitochondria so as to protect the heart. Nevertheless, results so far have been inconclusive.
Dr. Ong will present data from his team describing our efforts in modulating cardiac mitochondrial morphology to protect the heart against ischemia-reperfusion injury
