Mitochondrial Copper Toxicity with a Focus on Wilson Disease

Hans Zischka Targeting Mitochondria 2019

Prof. Hans Zischka from Institute of Molecular Toxicology and Pharmacology, Germany will present his team's research during the congress and will give a talk entitled "Mitochondrial Copper Toxicity with a Focus on Wilson Disease".

Summary of Talk: Wilson disease (WD) is a hereditary defect in the metabolism of copper. Here, the liver is unable to eliminate excess copper causing its accumulation primarily in liver and brain. In neurons and hepatocytes, a rising copper overload particularly damages their mitochondria. However, sometimes years pass before cell death occurs, suggesting the possible existence of intracellular protective mechanisms that can counteract such mitochondrial poisoning.

Therefore, we examined cell cultures from WD patients but also WD rodent models for their reaction to copper. We observed that the hepatocytes reacted to copper overload with an intensification of the mechanisms that support autophagy. Particularly, the copper-overloaded mitochondria are affected by this process (in this case called mitophagy). However, mitophagy helps only up to a certain level of copper overload and other treatments need to be employed to avoid cell death. Nevertheless, these results demonstrate the potential for cell regeneration resulting from auto-/mitophagy, which could also be relevant for other disorders that arise or are paralleled by cell-toxic metal accumulations.

Mitochondrial Antioxidant Therapy for Treating Vascular Aging

Douglas-R-Seals Mitochondria-2019

Prof. Seals will give a strategic talk on "Mitochondrial Antioxidant Therapy for Treating Vascular Aging".

The Scientific Committee of Targeting Mitochondria 2019 Congress is honored to announce Prof. Douglas R Seals from University of Colorado Boulder, USA will be joining us for our 10th Anniversary Edition of Targeting Mitochondria World Congress, which will be held in Berlin on October 28th-29th, 2019.

Summary of the Talk:  Arterial dysfunction is the major risk factor driving the dramatic increase in risk of cardiovascular diseases with aging.  Excessive superoxide production by mitochondria is a key mechanism underlying age-related vascular dysfunction and, as such, is a major therapeutic target for prevention of cardiovascular disorders.  I will discuss our translational research efforts to establish the efficacy of the mitochondrial antioxidant, MitoQ, for the treatment of arterial dysfunction with aging.

Increased Hydrogen Peroxide and Decreased Glutathione Redox Potential May Cause Dopaminergic Neurodegeneration in Parkin Loss-of-Function Drosophila

Lori Buhlman Targeting Mitochondria 2019The Scientific Committee of WMS is honored to announce that Dr. Lori Buhlman, Associate Professor from the College of Graduate Studies of Midwestern University, USA, will be joining us for our 10th Anniversary Edition of Targeting Mitochondria World Congress, which will be held in Berlin on October 28th-29th, 2019.

In her presentation entitled "Increased Hydrogen Peroxide and Decreased Glutathione Redox Potential May Cause Dopaminergic Neurodegeneration in Parkin Loss-of-Function Drosophila", Dr. Buhlman will discuss with us her recent studies on the mechanism of selective neurodegeneration in familial Parkinson’s disease. They use parkin loss-of-function Drosophila, which have selective dopaminergic neurodegeneration and motor behavior deficits.  "We have observed that degenerating neurons have transiently decreased mitophagy initiation, disrupted mitochondrial dynamics and increased mitochondrial protein oxidation, none of which were detected in non-degenerating dopaminergic neurons. Current goals are to understand important differences between vulnerable and non-degenerating dopaminergic degeneration in adult and developing flies and use genetic and pharmacological interventions to address them."

The cellular stress protein MNRR1/CHCHD2 and mitochondrial disease

lawrence-grossman Targeting Mitochondria 2019

Prof. Lawrence Grossman from Wayne State University, USA will join the Targeting Mitochondria 2019 congress and will give a talk entitled "The cellular stress protein MNRR1/CHCHD2 and mitochondrial disease".

Summary of talk: MNRR1 is a key mitochondrial stress regulator with the novel property of functioning in both the nucleus and the mitochondria yet having a different function in each organelle. Because cellular depletion of MNRR1 results in a phenocopy of some mitochondrial diseases, we investigated whether manipulating MNRR1 expression could reverse the cellular defects associated with them. Notably, in a model of the mitochondrial disease MELAS we could restore abnormal cellular functions by forced expression of MNRR1 or by its activation.

Mitochondrial reactive oxygen species in heart failure

Christoph Maack Mitochondria SpeakerProf. Christoph Maack from University Hospital Würzburg, Germany will join the Targeting Mitochondria 2019 Congress and  present his research work entitled  "Mitochondrial reactive oxygen species in heart failure".

The heart consumes large amounts of energy through the processes of excitation-contraction (EC) coupling in cardiac myocytes. To match energy supply to demand, mitochondria take up Ca2+ via the Ca2+ uniporter (MCU), where Ca2+stimulates rate-limiting enzymes of the Krebs cycle. The main products of the Krebs cycle, NADH and FADH2, donate electrons to the electron transport chain (ETC) to build up the mitochondrial membrane potential (DYm) that is the driving force for ATP production. Furthermore, Ca2+-induced Krebs cycle stimulation also regenerates NADPH for the antioxidative capacity of the mitochondrial matrix. 

Prof. Maack will highlight exactly what we obserse in heart failure during the Targeting Mitochondria Congress.

Mitochondria and Skin: A dedicated session during Targeting Mitochondria 2019

Sibylle Jager Targeting Mitochondria 2019 CongressDr. Sibylle Jäger from L’Oréal Research & Innovation, France will join the Targeting Mitochondria 2019 Congress and speak about a dedicated session during   "Role of PGC-1s in human epidermal physiology".

During Targeting Mitochondria 2019, a Special session will be dedicated to Mitochondria, Metabolism and Skin. One of the speakers of this session will be Dr. Sibylle Jäge.

She will highlight: "Altered metabolism is a hallmark of aging, and key regulators of metabolism, notably members of the peroxisome proliferator activated receptor gamma coactivator (PGC)-1 family have been implicated in aging and its associated conditions. However, the roles of PGC-1s in skin physiology and aging have been largely unexplored. She investigated the potential role of PGC-1s in skin using human epidermal primary keratinocytes and living epidermal equivalents. Overall, her results show that PGC-1s are essential components of epidermal physiology, revealing a novel axis that could be targeted in skin conditions and aging".

Cannabinoids and skin: The "C(ut)annabinoid" system as a novel player in regulating cutaneous mitochondrial biology by Dr. Oláh

Attila Olah Targeting Mitochondria 2019

During the specical session dedicated to the Mitochondria and Skin, Dr. Attila Oláh from University of Debrecen, Hungary will give a presentation entitled "Cannabinoids and skin: The "C(ut)annabinoid" system as a novel player in regulating cutaneous mitochondrial biology".

According to Dr. Oláh:

Although the mitochondrial biology of the skin is a relatively less-studied area of the field, a growing body of evidence suggests that it is profoundly involved in the regulation of several aspects of cutaneous physiology, including, but not limited to hair growth, epidermal differentiation and (photo) aging. The current talk intends to provide a brief overview of recent literature data with promising translational potential, and to highlight the potential role of the cutaneous cannabinoid (“C(ut)annabinoid”) system in controlling mitochondrial activity in the skin.

Mitochondria-targeted low-molecular weight compounds for probing mitochondrial function

Richard-C.-Hartley-Mitochondria-2019-congressThe Scientific Committee of WMS is honored to announce that Prof. Richard C. Hartley, Professor of Chemical Biology from University of Glasgow, United Kingdom, will be joining us for our 10th Anniversary Edition of Targeting Mitochondria World Congress, which will be held in Berlin on October 28th-29th, 2019.

During the Congress Prof. Richard C. Hartley will speak about "Mitochondria-targeted low-molecular weight compounds for probing mitochondrial functions".

The Hartley group specializes in designer small molecules targeted to accumulate in the mitochondrial matrix.  These can be used both to detect and manipulate mitochondrial redox processes.  Examples include compounds for mitochondrial  superoxide detection (MitoNeoD) and generation (MitoPQ), for selective depletion of mitochondrial antioxidant defences (MitoCDNB), and for mitochondrial protection (MitoGamide).  Synthetic chemicals can also be used to mimic mitochondrial signaling and modulate inflammatory responses (octyl itaconate).
