“Molecular and Cellular Responses to the Shortest Telomere in Saccharomyces cerevisiae”
directed by Dr Teresa Teixeira.
The defense will take place on Friday, October 11, 2024, at 2:00 PM, in the Edmond de Rothschild Library at the Institut de Biologie Physico-Chimique (IBPC), located at 13 rue Pierre et Marie Curie, 75005 Paris.
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.
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).
Replicative senescence is triggered when telomeres reach critically short length and activate permanent DNA damage checkpoint-dependent cell cycle arrest.
