ALT Telomeres Get Together with Nuclear Receptors

Joachim Lingner, Eric Aeby

Nuclear receptors bind chromosome ends in "alternative lengthening of telomeres" (ALT) cancer cells that maintain their ends by homologous recombination instead of telomerase. Marzec et al. now demonstrate that, in ALT cells, nuclear receptors not only tri ...

The double life of UPF1 in RNA and DNA stability pathways

Joachim Lingner

The DNA and RNA helicase UPF1 is well known for its central role in Nonsense Mediated RNA Decay (NMD), which promotes degradation of mRNAs containing premature stop codons. However, we have recently demonstrated that human UPF1 is also essential for DNA re ...

Protein-RNA and protein-protein interactions mediate association of human EST1A/SMG6 with telomerase

Joachim Lingner, Sophie Redon

The human EST1A/SMG6 polypeptide physically interacts with the chromosome end replication enzyme telomerase. In an attempt to better understand hEST1A function, we have started to dissect the molecular interactions between hEST1A and telomerase. Here, we d ...

The human telomeric proteome during telomere replication

Chih-Yi Gabriela Lin, Joachim Lingner, Aleksandra Vancevska, Thomas Frédéric Lunardi, Gérald Joseph Paul Lossaint

Telomere shortening can cause detrimental diseases and contribute to aging. It occurs due to the end replication problem in cells lacking telomerase. Furthermore, recent studies revealed that telomere shortening can be attributed to difficulties of the sem ...

Telomere functions grounding on TERRA firma

Joachim Lingner

Long noncoding telomeric repeat-containing RNAs TERRAs - are transcribed in a regulated manner from telomeres throughout eukaryotes. TERRA molecules consist of chromosome end-specific subtelomeric sequences and telomeric repeats at their 3' ends. Recent wo ...

TFIIH moonlighting at telomeres

Joachim Lingner, Galina Glousker

Although telomeres are essential for chromosome stability, they represent fragile structures in our genome. Telomere shortening occurs during aging in cells lacking telomerase due to the end replication problem. In addition, recent work uncovered that the ...

Telomerase RNAs of different ciliates have a common secondary structure and a permuted template

Joachim Lingner

Telomerase is composed of protein and RNA. The RNA serves as a template for telomere DNA synthesis and may also be important for enzyme structure or catalysis. We have used the presence of conserved sequence elements in the promoter and template regions to ...

Telomerase repeat addition processivity is increased at critically short telomeres in a Tel1-dependent manner in Saccharomyces cerevisiae

Joachim Lingner

Telomerase is the ribonucleoprotein enzyme that elongates telomeres to counteract telomere shortening. The core enzyme consists of a reverse transcriptase protein subunit and an RNA subunit. The RNA subunit contains a short region that is used as a templat ...

Functional characterization of the TERRA transcriptome at damaged telomeres

Joachim Lingner, Jacques Rougemont, Antonio Porro, Sascha Feuerhahn

Telomere deprotection occurs during tumorigenesis and aging upon telomere shortening or loss of the telomeric shelterin component TRF2. Deprotected telomeres undergo changes in chromatin structure and elicit a DNA damage response (DDR) that leads to cellul ...

Telomerase Inhibitors from Cyanobacteria: Isolation and Synthesis of Sulfoquinovosyl Diacylglycerols from

Karl Gademann, Joachim Lingner, Gerardo Turcatti, Cyril Portmann, Damiano Banfi, Emilie Baudat

By using the Telospot assay, 27 different extracts of cyanobacteria were evaluated for telomerase inhibition. All extracts showed varying, but significant activity. We selected Microcystis aeruguinosa PCC 7806 to identify the active compound and a bioassay ...

Tel1 kinase and subtelomere-bound Tbf1 mediate preferential elongation of short telomeres by telomerase in yeast

Joachim Lingner

Telomerase enables telomere length homeostasis, exhibiting increasing preference for telomeres as their lengths decline. This regulation involves telomere repeat-bound Rap1, which provides a length-dependent negative feedback mechanism, and the Tel1 and Me ...

Telomerase unplugged

Joachim Lingner, Katarzyna Sikora

The control of telomerase activity at chromosome ends by telomere-binding proteins is critical for telomere length homeostasis. Two recent papers identify TPP1 as a critical mediator of this control. TPP1 forms part of the telomeric shelterin complex while ...

CST for the grand finale of telomere replication

Joachim Lingner, Liuh-Yow Chen

Telomeric DNA at eukaryotic chromosome ends terminates with single stranded 3' G-rich overhangs. The overhang is generated by the interplay of several dynamic processes including semiconservative DNA replication, 3' end elongation by telomerase, C-strand f ...

When Telomerase Causes Telomere Loss

Joachim Lingner, Galina Glousker

Telomerase counteracts telomere shortening, preventing cellular senescence. Telomerase deficiency causes telomere syndromes because of premature telomere exhaustion in highly proliferative cells. Paradoxically, in a recent issue of Cell, Margalef et al. (2 ...

Human protection of telomeres 1 (POT1) is a negative regulator of telomerase activity in vitro

Joachim Lingner

The telomeric single-strand DNA binding protein protection of telomeres 1 (POT1) protects telomeres from rapid degradation in Schizosaccharomyces pombe and has been implicated in positive and negative telomere length regulation in humans. Human POT1 appear ...
