Cell lineage tracing in human tissues using somatic mitochondrial mutations

Paul Refinetti

Lineage tracing is a basic concept in developmental biology, as well as diseases related to organ development. A reliable method to track cell lineages in human tissues has the potential to greatly contribute to the fields of oncogenesis, tissue renewal, a ...

Mitochondria and Epigenetics Crosstalk in Homeostasis and Stress

Johan Auwerx

Through epigenetic mechanisms cells integrate environmental stimuli to fine-tune gene expression levels. Mitochondrial function is essential to provide the intermediate metabolites necessary to generate and modify epigenetic marks in the nucleus, which in ...

Is detection of intraperitoneal exfoliated tumor cells after surgical resection of rectal cancer a prognostic factor of survival?

Paul Refinetti

Background: The prognostic significance of free cancer cells detected in peritoneal fluid at the time of rectal surgery remains unclear. A substantial number of patients will develop metastatic disease even with successful local treatment. This prospective ...

Mapping mitochondrial heteroplasmy in a Leydig tumor by laser capture microdissection and cycling temperature capillary electrophoresis

Stephan Morgenthaler, Paul Refinetti

Background: The growth of tumor cells is accompanied by mutations in nuclear and mitochondrial genomes creating marked genetic heterogeneity. Tumors also contain non-tumor cells of various origins. An observed somatic mitochondrial mutation would have occu ...

Cycling temperature capillary electrophoresis: A quantitative, fast and inexpensive method to detect mutations in mixed populations of human mitochondrial DNA

Stephan Morgenthaler, Paul Refinetti

Cycling temperature capillary electrophoresis has been optimised for mutation detection in 76% of the mitochondrial genome. The method was tested on a mixed sample and compared to mutation detection by next generation sequencing. Out of 152 fragments 90 we ...

Modulation of AMPK's activity via genetic tools and food-derived compounds as a novel approach to Parkinson's disease treatment

Wojciech Janusz Bobela

Aging is considered as a major risk factor for Parkinsonâ s disease (PD) and can be defined as a gradual decline in the ability of biological systems to efficiently renew structural and functional components, which may lead to perturbations in energetic h ...

Mitochondrial DNA Analyses Indicate High Diversity, Expansive Population Growth and High Genetic Connectivity of Vent Copepods (Dirivultidae) across Different Oceans

Stefan Jean Laurent

Communities in spatially fragmented deep-sea hydrothermal vents rich in polymetallic sulfides could soon face major disturbance events due to deep-sea mineral mining, such that unraveling patterns of gene flow between hydrothermal vent populations will be ...

The evolution of gene expression and binding specificity of the largest transcription factor family in primates

Didier Trono, Jeffrey David Jensen, Adamantia Kapopoulou

The KRAB-containing zinc finger (KRAB-ZF) proteins represent the largest family of transcription factors (TFs) in humans, yet for the great majority, their function and specific genomic target remain unknown. However, it has been shown that a large fractio ...

Mitochondrial unfolded protein response, its molecular mechanism and physiological impact

Virginija Jovaisaite

Mitochondria are the main producers of ATP, the energy currency of the cell, and they perform a wide array of other fundamental functions. These organelles are essential not only for cellular metabolism, but also for organismal physiology and lifespan. A r ...

The mitochondrial unfolded protein response - synchronizing genomes

Johan Auwerx, Virginija Jovaisaite

Maintenance of the mitochondrial proteome is performed primarily by chaperones, which fold and assemble proteins, and by proteases, which degrade excess damaged proteins. Upon various types of mitochondrial stress, triggered genetically or pharmacologicall ...

A method to identify and validate mitochondrial modulators using mammalian cells and the worm C-elegans

Johan Auwerx, Laurent Mouchiroud, Richardus Houtkooper, Norman Lionel Moullan, Pénélope Andreux, Adrienne Joëlle Laurence Mottis, Xu Wang, Virginija Jovaisaite

Mitochondria are semi-autonomous organelles regulated by a complex network of proteins that are vital for many cellular functions. Because mitochondrial modulators can impact many aspects of cellular homeostasis, their identification and validation has pro ...
