Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy that harbors mutations in homologous recombination–repair (HR-repair) proteins in 20%–25% of cases. Defects in HR impart a specific vulnerability to poly ADP ribose polymerase

Telomerase plays a key role in the immortalization of cancer cells by maintaining telomeres length. Using single-molecule imaging of telomerase RNA molecules in cancer cells, we recently reported novel insights into the role of Cajal bodies in telome

Summary: Fluorescent in situ hybridization (FISH) on the RNA moiety of human telomerase (hTR) with 50-mer probes detects hTR RNA accumulated in Cajal bodies. Using both live-cell imaging and single-molecule inexpensive FISH, our published work reveal

Telomeres are distinctive structures that protect the ends of linear chromosomes and ensure genome stability. They are composed of long tracks of repetitive and G-rich DNA that is bound by shelterin, a dedicated six-subunit protein complex. In somati

Genome sequencing studies have revealed a number of cancer-associated mutations in the telomere-binding factor POT1. Here, we show that when combined with p53 deficiency, depletion of murine POT1a in common lymphoid progenitor cells fosters genetic i

In mammals, the conserved telomere binding protein Rap1 serves a diverse set of nontelomeric functions, including activation of the NF-kB signaling pathway, maintenance of metabolic function in vivo, and transcriptional regulation. Here, we uncover t

The yeast homologs of the ATM and ATR DNA damage response kinases play key roles in telomerase-mediated telomere maintenance, but the role of ATM/ATR in the mammalian telomerase pathway has been less clear. Here, we demonstrate the requirement for AT

Double-strand breaks in mitochondrial DNA (mtDSBs) lead to the degradation of the circular genomes and a reduction in copy number. However, it is unclear how mtDSBs are sensed and what signaling pathways are activated in response to mtDNA damage. In
