We are excited that our study on telomere sequencing in collaboration with @nanopore is published https://t.co/CZvLmrIONf We developed Telo-seq, a method to determine the length and composition of entire human telomeres in bulk, chromosome arm and in some cases allelic resolution

Introducing Telo-seq: a new tool from @SalkInstitute and Oxford @Nanopore that will revolutionize the study of aging and cancer. Scientists can now measure and sequence telomeres on individual chromosomes with unprecedented resolution. #SalkHealthyAging

LA JOLLA—Within each of our cells, long strands of DNA are folded into chromosomes and capped with protective structures called telomeres. But telomeres shorten as we age, eventually getting so...

We applied Telo-seq to resolve telomere dynamics during cellular aging and reprogramming as well as differences in TERT- and ALT-positive cancer cells. Congrats to the entire team and big thanks to all our collaborators! @NatureComms

Learn how @KarlsederLab & team used nanopore technology to investigate telomere shortening during cellular aging. Check out how they also studied how alternative lengthening of telomeres and telomerase impact iPSCs and cancer cells. Read more: https://t.co/5yAeZW6gcE

Our preprint “High resolution long-read telomere sequencing reveals dynamic mechanisms in aging and cancer” is now on bioRxiv.

Telomeres are the protective nucleoprotein structures at the end of linear eukaryotic chromosomes. Telomeres’ repetitive nature and length have traditionally challenged the precise assessment of the...

Our latest review 'Telomeres as hotspots for innate immunity and inflammation' is now live @repair_dna! Here, we describe how dysfunctional telomeres activate innate immune pathways and fuel inflammaging. Check it out @Sprzetocka @KarlsederLab

Some tumors repair their DNA via microhomology-mediated end joining (MMEJ), rather than with homologous recombination (HR). Scientists find that MMEJ relies on the APE2 nuclease, revealing a chink in the armor of HR-deficient cancers. @ArnoultLab

Great job to the Arnoult lab for their recent publication in Molecular Cell! Their study highlights the critical role that APE2 nuclease plays in Pol Theta-mediated MMEJ. Congratulations!🥳

Our results also indicate that TZAP binding to telomeres induces telomere dysfunction and ALT-like activity, leading to the generation of t-circles and c-circles through a BTR-dependent process. Congrats to Sara (@Sara_Priego_89), Javier, and the entire team!

We found that efficient TZAP recruitment to telomeres occurs when telomeric chromatin is open due to the loss of ATRX/DAXX, independently of H3.3 deposition.

Our latest study, in collaboration with @ErosLazzerini, sheds light on the molecular mechanisms of the pathway triggered by the telomeric-associated zinc-finger protein (TZAP) in human cancer cells. https://t.co/AVBXuMHSga
