Seminaire de Eros Lazzerini Denchi
Telomeres, the natural ends of chromosomes, resemble double-strand breaks (DSBs) and require protection by the shelterin complex to prevent aberrant activation of the DNA damage response (DDR) in somatic cells.

Outer mitochondrial membrane fusion, a vital cellular process, is mediated by mitofusins. However, the underlying molecular mechanism remains elusive.

Séminaire du Prof. Dennis KAPPEI
Telomere maintenance is a universal hallmark of cancers to sustain the unlimited proliferative potential. In ~85% of cancers, telomere shortening is mitigated by reactivated telomerase expression while the other ~15% use a recombination-based mechanism, termed Alternative Lengthening of Telomeres (ALT)

Nouvelle publication de l’équipe Biologie des télomères
Replicative senescence is triggered when telomeres reach critically short length and activate permanent DNA damage checkpoint-dependent cell cycle arrest.

Mitofusins are large GTPases that trigger fusion of mitochondrial outer membranes. Similarly to the human mitofusin Mfn2, which also tethers mitochondria to the endoplasmic reticulum (ER), the yeast mitofusin Fzo1 stimulates contacts between Peroxisomes and Mitochondria when overexpressed.
