• February 8, 2024 : Single molecule observations of mitochondrial DNA compaction,

Géraldine Farge: associate professor, LPCA
Siet van den Wildenberg: research engineer, LPCA

Several mutations in mitochondrial DNA replication factors have been associated with mitochondrial diseases. They are mainly mutations in the helicase Twinkle and the mitochondrial replicative DNA polymerase POLG, and insights into the molecular mechanisms underlying the function of these factors in health and disease have been provided. However, despite being “good” candidates for mtDNA maintenance disorders, TFAM (Mitochondrial Transcription Factor A) and mtSSB (mitochondrial single-stranded DNA binding protein) were only recently pathogenically associated to human diseases. Over the last two decades, many strategies have been developed to manipulate and watch single proteins working on a DNA molecule, and from being proof of principle “curiosities”, they now provide essential contributions to the study of biological transactions on DNA.

Pierre-Jean Gauthier: Researcher at LMV since 2000. Specialist in short-lived radioactivity in gases and magmas, applied to the study of the dynamics of superficial magmatic reservoirs in relation to eruptive activity. Study of the degassing of magmas and the environmental impact of volcanism. Some target volcanoes: Etna and Stromboli, Italy; Merapi, Indonesia; Erebus, Antarctica; Yasur and Ambrym, Vanuatu; Masaya, Nicaragua (IP project I-SITE Nicaragua). VIDEO, PDF

Magali Magne: Electronic engineer at LPC since the end of 2003. She worked on several experiments of various sizes and in different fields: LHCb(CERN)/DVSC(JLAB)/ Avirm(lab)/LHCb Scifi(CERN)/Ravioli (Lab). She started a collaboration with the environment team at the end of 2019 on the Ravioli then Calorado projects. VIDEO , PDF
