Mitophagy Activation by Urolithin A to Target Muscle Aging

The age-related loss of skeletal muscle function starts from midlife and if left unaddressed can lead to an impaired quality of life. A growing body of evidence indicates that mitochondrial dysfunction is causally involved with muscle aging. Muscles are ti ...

The molecular treasure box of environmental Vibrio cholerae strains

Natalia Carolina Drebes Dorr

Cholera pandemics have been affecting humankind for centuries and are still considered a major public health problem, especially in regions around the world with poor access to clean water and sanitation. Cholera pandemics are caused by a specific lineage ...

Disturbed mitochondrial dynamics in CD8(+)TILs reinforce T cell exhaustion

Li Tang, George Coukos, Marcela Rincón-Restrepo, Nicola Vannini, Min Gao, Fabien Franco

Ho and colleagues report that mitochondrial dysfunction and impaired mitophagy triggered by the tumor microenvironment lead to subsequent epigenetic changes and cause permanent T cell exhaustion and dysfunction. The metabolic challenges present in tumors a ...

Protein Engineering Tools to Explore the Function of Protein Post-Translational Modifications for Chromatin and Microtubule Cytoskeletal Biology

Ninad Dilip Agashe

Protein post-translational modifications (PTMs) play a crucial role in expanding the protein diversity and are one of the major mechanisms through which cells respond to ever changing environmental cues. The function of two of the most important cellular c ...

Structure of a PSI-LHCI-cyt b(6)f supercomplex in Chlamydomonas reinhardtii promoting cyclic electron flow under anaerobic conditions

Henning Paul-Julius Stahlberg

Photosynthetic linear electron flow (LEF) produces ATP and NADPH, while cyclic electron flow (CEF) exclusively drives photophosphorylation to supply extra ATP. The fine-tuning of linear and cyclic electron transport levels allows photosynthetic organisms t ...

A synthetic biology approach to engineering living photovoltaics

Ardemis Anoush Boghossian

The ability to electronically interface living cells with electron accepting scaffolds is crucial for the development of next-generation biophotovoltaic technologies. Although recent studies have focused on engineering synthetic interfaces that can maximiz ...

Pro-oxidant effects of nano-TiO2 on Chlamydomonas reinhardtii during short-term exposure

Olivier Martin, Paul Bowen, Christian Santschi, Lionel André Maurizi, Volodymyr Koman, Nadia Rachel Von Moos, Amarnath Jayaprakash

This study sheds light on the short-term dynamics of pro-oxidant processes related to the exposure of C. reinhardtii microalgae to nano-TiO2 using (a) conventional fluorescence probes for cellular pro-oxidant process and (b) a recently developed cytochrome ...

On the statistical physics of chains and rods, with application to multi-scale sequence-dependent DNA modelling

Alexandre Emmanuel Grandchamp

The complex mechanisms involved in cellular processes have been increasingly understood this past century and the central role of the DNA molecule has been recognized. The base pair sequence along a DNA fragment is observed not only to encode the genomic i ...

Traceless Synthesis of Asymmetrically Modified Bivalent Nucleosomes

Beat Fierz, Carolin Christine Lechner, Ninad Dilip Agashe

Nucleosomes carry extensive post-translational modifications (PTMs), which results in complex modification patterns that are involved in epigenetic signaling. Although two copies of each histone coexist in a nucleosome, they may not carry the same PTMs and ...

Multiple stressor effects in Chlamydomonas reinhardtii - Toward understanding mechanisms of interaction between effects of ultraviolet radiation and chemical pollutants

Renata Behra

The effects of chemical pollutants and environmental stressors, such as ultraviolet radiation (UVR), can interact when organisms are simultaneously exposed, resulting in higher (synergistic) or lower (antagonistic) multiple stressor effects than expected b ...
