mTert induction in p21-positive cells counteracts capillary rarefaction and pulmonary emphysema
EMBO ReportsLung diseases develop when telomeres shorten beyond a critical point. We constructed a mouse model in which the catalytic subunit of telomerase (mTert), or its catalytically inactive form (mTertCI), is expressed from the p21Cdkn1a locus.

EMBO Molecular Medicine, 2015 Telomeres are considered anti‐cancer targets, as telomere maintenance above a minimum length is necessary for cancer growth. Telomerase abrogation in cancer‐prone mouse models, however, only decreased tumor growth after several mouse generations when ...

Advancing Precision Nutrition Through Multimodal Data and Artificial Intelligence
Advanced Science, EarlyView.Individual responses to food vary dramatically, challenging traditional dietary advice. This review explores how the unique genetic makeup, gut microbiome, and brain activity shape host metabolic health. We examine how artificial intelligence integrates these multimodal data to predict individualized dietary needs, moving beyond one‐size‐fits‐all ...

Advanced Science, EarlyView.This study identifies mutation‐intolerant genes (MIGs), which are mutationally constrained in tumors despite normal‐tissue variability. Using miDriver, the authors pinpoint MIGs essential for tumor‐intrinsic fitness and immune evasion. Focusing on CHEK1, they show it drives tumor fitness and sculpts an immunosuppressive niche via the MIF–CD74 axis ...

Chromatin features of plant telomeric sequences at terminal versus internal positions
Frontiers in Plant Science, 2014 Epigenetic mechanisms are involved in regulation of crucial cellular processes in eukaryotic organisms. Data on the epigenetic features of plant telomeres and their epigenetic regulation were published mostly for Arabidopsis thaliana, in which the ...

Advanced Science, EarlyView.The RNA G‐quadruplexes formed at the 5'‐end of the RNA component of human telomerase possess extreme slow unfolding rate, rendering them resistant to nuclease degradation. The helicase DHX36 overcame this kinetic barrier and significantly reduced the folded fraction.

Telomeres, a Busy Platform for Cell Signaling
Frontiers in Oncology, 2013 Telomeres are the terminal structures at the ends of linear chromosomes that represent a solution to the end replication problem. Specific binding of the six-protein subunit complex shelterin to telomeric, repetitive TTAGGG DNA sequences contributes to ...

Advanced Science, EarlyView.G4‐binding proteins (G4BPs) that specifically co‐bind G4s in the presence of small‐molecule ligands represent a critical but unexplored class of proteins. We introduce G4‐Ligand‐Directed PROTACs (G4L‐TACs), a chemical platform that couples G4 ligands (PDS) to E3 recruiters to selectively degrade these ligand‐co‐binding G4BPs.

Highly Aggressive Metastatic Melanoma Cells Unable to Maintain Telomere Length
Cell Reports, 2017 Summary: Unlimited replicative potential is one of the hallmarks of cancer cells. In melanoma, hTERT (telomerase reverse transcriptase) is frequently overexpressed because of activating mutations in its promoter, suggesting that telomerase is necessary ...
