Mitochondria and Skin: A dedicated session during Targeting Mitochondria 2019
Dr. 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".

Mitochondrial damage and renewal in Wilson disease will be presented by Prof. Hans Zischka
Prof. Hans Zischka from Institute of Molecular Toxicology and Pharmacology, Germany will speak about "Mitochondrial damage and renewal in Wilson disease".
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.
Prof. Zischka examined cell cultures from WD patients but also WD rodent models for their reaction to copper.
He observed that the hepatocytes reacted to copper overload with an intensification of the mechanisms 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 be also relevant for other disorders that arise or are paralleled by cell-toxic metal accumulations.

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

Mitochondrial Transplantation - From Animal Studies to Clinical Relevance
The Scientific Committee of WMS is honored to announce that Dr. James McCully, from the Harvard Medical School Department of Cardiac Surgery Boston Children’s Hospital, 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 his presentation entitled "Mitochondrial Transplantation - From Animal Studies to Clinical Relevance", Dr. McCully will share his studies using a novel therapy for cardioprotection based on mitochondrial transplantation. This approach uses replacement of native mitochondria damaged by ischemia/reperfusion injury with viable, respiration-competent mitochondria isolated from non-ischemic skeletal muscle tissue, obtained from the patient’s own body. Dr. McCully will provide results and insight from ischemia/ reperfusion protocols in regionally ischemic animal heart models and from a Phase 1 clinical trial in pediatric patients requiring institution of extracorporeal membrane oxygenation support.

Cardiac glycosides modulate neuroblastoma stem cell survival by dysfunctional mitophagy
The Scientific Committee of WMS is honored to announce that Dr. Marc Diederich, from the College of Pharmacy, Seoul National University, Korea, 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 his presentation entitled "Cardiac glycosides modulate neuroblastoma stem cell survival by dysfunctional mitophagy", Dr. Diederich will discuss the limiting factor to producing successful therapeutic outcomes in children with high-risk neuroblastoma, resistant to chemotherapeutic therapies. Therefore, a better characterisation of sensitive versus resistant neuroblastoma cell types is urgently required. Our previous research showed that the cardiac glycoside (CG) UNBS1450 (1,2) exerted its anti-cancer activity in neuroblastoma through an early induction of mitophagy in response to a mitochondrial stress response: whereas UNBS1450 rapidly promoted apoptosis in N-type (SH-SY5Y) cells, necroptosis was triggered in the more resistant S-type (SK-N-AS) cells at higher concentrations and later time points. In SH-SY5Y cells, reactive oxygen species generation triggered loss of Δψ and accumulation of mitochondria in phagophores/autophagosomes, suggesting impaired clearance of damaged mitochondria (3). Moreover, differential expression of p53, stem cell homeostasis, and pluripotency recently gained interest in neuroblastoma research. Here, we aimed at identifying critical determinants of the differential sensitivity towards UNBS1450 in neuroblastoma cells to improve prediction of the treatment response. First, we selected the most sensitive neuroblastoma cell subtype based on p53 and neuroblastoma CSC marker expression levels. Second, in the most sensitive subtype, we further aimed at assessing mitochondrial quality control mechanisms to identify mitochondrial biomarkers of UNBS1450 efficacy.

Stem cell-driven drug discovery of OXPHOS diseases
The Scientific Committee of WMS is honored to announce that Dr. Alessandro Prigione, Independent Team Leader, at the Max Delbrueck Center for Molecular Medicine, Germany, 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 his presentation entitled "Stem cell-driven drug discovery of OXPHOS diseases", Dr. Prigione will discuss Mutations in the mitochondrial complex IV assembly factor SURF1, representing a major cause of Leigh syndrome (LS), a rare fatal neurological disorder. SURF1-deficient animals have failed to recapitulate the neuronal pathology of LS, hindering our understanding of the disease mechanisms. We generated induced pluripotent stem cells from LS patients carrying homozygous SURF1 mutations (SURF1 iPS) and performed biallelic correction via CRISPR/Cas9. In contrast to corrected cells, SURF1 iPS showed impaired neuronal differentiation. Aberrant bioenergetics in SURF1 iPS occurred already in neural progenitor cells (NPCs), disrupting their neurogenic potency. Cerebral organoids from SURF1 iPS were smaller and recapitulated the neurogenesis defects. Our data imply that SURF1 mutations cause a failure in the development of maturing neurons. Using NPC function as an interventional target, we identified SURF1 gene augmentation as a potential strategy for restoring neurogenesis in LS patients carrying SURF1 mutations.

Selective segregation of mitochondria in asymmetric stem cell divisions
The Scientific Committee of WMS is honored to announce that Assoc. Prof. Pekka Katajisto, Associate Professor in Karolinska Institutet and University of Helsinki, Finland, as well as Director of the Center of Excellence in Stem Cell Metabolism, 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 his presentation entitled "Selective segregation of mitochondria in asymmetric stem cell divisions", Dr. Pekka Katajisto will share with us his studies that could be introduced as such: "Tissue resident stem cells renew and repair our tissues. However, in order to secure tissue homeostasis, generation of new stem cells via self-renewal and their differentiation in to functional cells must be carefully balanced. During aging, multiple types of alterations directly in stem cells, or in their tissue neighbourhood can disturb this balance. Our laboratory studies both stem cell intrinsic, and extrinsic mechanisms altering tissue renewal capacity."
