April News from the SFRR-E ECR subcommittee

Dear colleagues, 

In today's newsletter, we will announce our next webinar on the topic “Inter-tissue communication”. We will also share with you a summary of April’s “Redox control of aging” webinar, in case some of you didn’t have the chance to join. At the end of the newsletter, as always, you can also find a collection of upcoming events with important deadlines and some suggestions of interesting redox reads recently published.

Webinar series “Emerging leaders in redox biology”

Our next webinar will be on 7th May 2024 at 15:00 CET on the topic “Inter-tissue communication” featuring Cristina Mas-Bargues and Renato Simoes Gaspar.

Redox modulation in aging mediated by stem cell-derived extracellular vesicles

Cristina Mas-Bargues, PhD
Department of Physiology, School of Medicine, University of Valencia, Spain

Cristina Mas-Bargues started her research on stem cell aging and oxidative stress. She obtained her PhD in 2017 at the University of Valencia, and performed two stays during her predoc and postdoc training at the University of California at Berkeley, and at the Albert Einstein College of Medicine at New York, respectively. She is currently an Assistant Professor working at the Department of Physiology, University of Valencia, Spain. Nowadays, her research focuses on extracellular vesicles obtained from stem cells, and their application on regenerative medicine.


Thinking redox outside of the cell: how an ER-resident chaperone governs cellular adhesion and the extracellular matrix

Renato Simoes Gaspar, PhD
State University of Campinas (UNICAMP), Sao Paulo, Brazil

My research interests started during my medical degree at the Federal University of Maranhão (Brazil). From there, I developed a marked curiosity to understand how redox processes regulate platelet physiology during my PhD at the University of Reading (UK) under the (super fun) supervision of Prof Jonathan Gibbins. At the start of the COVID pandemic, I decided to go back to Brazil and pursue a postdoctoral fellowship with Dr Francisco Laurindo at the Heart Institute of the University of São Paulo. There I studied how an extracellular thiol isomerase, PDIA1, influenced platelet-endothelium interaction in hyperglycemia. This work has sparked my curiosity towards proteins of the extracellular matrix (ECM) and has developed into an independent research grant. Currently, I am starting my laboratory focused on ECM proteins (aka the ECM lab) at the State University of Campinas (UNICAMP), in Brazil. We aim to find mechanisms that explain how cells of the cardiovascular system "sense" modified ECM proteins and how these are relevant to cardiovascular diseases.

April’s webinar

On April’s webinar we enjoyed two inspiring talks on the topic “Redox control of aging” by Daphne Bazopoulou and Helena Cochemé.

The impact of early-in-life redox signaling in health, aging and disease

Daphne Bazopoulou, PhD

Biology of Stress and Aging Lab, Department of Biology, University of Crete, Greece

Dr. Bazopoulou gave a fascinating talk about early life events that can shape organismal health in the long term and the aging process, focusing on recent observations on ROS and the implication of redox regulated events in these processes.

For their work they use C. elegans since they are an optimal animal model to study individual aging. Using C. elegans with Grx1-roGFP2 they saw that oxidation levels arise during adulthood and in the early developmental stages. This highly oxidized environment in early developmental stages is critical for redox signaling whereas during late adulthood is associated with oxidative damage. They saw that during development, the worms which showed increased oxidation levels had improved homeostasis and that it was due to an epigenetic modifier (H3K4 trimethylation) and that this gave the worms increased stress resistance and longer lifespan. They came up with the question: might ROS be a universal pro-longevity signal? In order to find an answer, they are focusing on two mechanisms: dietary restriction and host-microbiome interactions. Very interestingly, they found that ROS via H3K4me3 are implicated in lifespan regulation conferred by dietary restriction and that ROS act via bacterial metabolism to regulate host lifespan. Finally, she showed results of their investigation on the redox regulation of host-immune responses. 105 immune genes were upregulated upon mild oxidation in developing worms. When exposing worms to pathogenic bacteria, their oxidation levels increased and H3K4me3 levels drastically decreased.

Redox signaling in aging

Helena Cochemé, PhD

Redox Metabolism Group, MRC Laboratory of Medical Sciences, London, United Kingdom

Dr. Cochemé gave an interesting talk on the important role of redox signaling in aging. Her interest in redox signaling and aging started during her PhD and Postdoc, where she found that levels of mitochondrial H2O2 increase with age in Drosophila. Afterwards, she wanted to follow up on what the consequences of the increased ROS production are.
Helene showed that upregulation of catalase in Drosophila leads to lifespan extension. Moreover, the flies were very resistant to oxidative stress but interestingly, the flies were more sensitive to starvation. No differences were found in TAG or glycogen leading to the hypothesis that autophagy might be involved. Indeed, autophagy is induced in the catalase overexpressed flies, with Atg4a playing an important role. Her group found that catalase overexpression quenches redox signaling by H2O2 alering redox signaling at the levels of Atg4a. This oxidizing shift of a catalytic cysteine in Atg4a mimics an internal state of oxidation that leads to upregulation of autophagy. By changing the redox-sensitive cysteine is Atg4a to a redox-insensitive serine, autophagy induction by catalase is prevented and lifespan extension is lost. Remarkably, a single residue can exert profound effects on both metabolism and survival.

SFRR-E Visiting Fellowships 2024
