Regulation and impact of TERRA R-loops at human telomeres

Rita Valador Fernandes

Telomeres are the nucleoprotein structures found at the ends of linear chromosomes. They ensure that the termini of chromosomes are not inappropriately recognized as sites of DNA damage, and are therefore crucial for genome stability. In spite of the heter ...

Preomic profile of BxPC-3 cells after treatment with BRC4

Andrea Cavalli

BRCA2 and RAD51 are two proteins that play a central role in homologous recombination (HR) and DNA double strand break (DSB) repair. BRCA2 assists RAD51 fibrillation and defibrillation through binding with its eight BRC repeats, with BRC4 being one of the ...

Recycling of Polymerase Chain Reaction (PCR) Kits

Francesco Stellacci, Weina Liu, Yong Zhu

Polymerase chain reaction (PCR) kits have been used as common diagnosing tools during the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, with daily worldwide usage in the millions. It is well known that at the beginn ...

Relief of ParB autoinhibition by parS DNA catalysis and recycling of ParB by CTP hydrolysis promote bacterial centromere assembly

Paolo De Los Rios, Stefano Zamuner

Three-component ParABS systems are widely distributed factors for plasmid partitioning and chromosome segregation in bacteria. ParB acts as adaptor protein between the 16-base pair centromeric parS DNA sequences and the DNA segregation proteins ParA and Sm ...

PRDX1 Counteracts Catastrophic Telomeric Cleavage Events That Are Triggered by DNA Repair Activities Post Oxidative Damage

Wareed Ahmed

Telomeres are prone to damage inflicted by reactive oxygen species (ROS). Oxidized telomeric DNA and nucleotide substrates inhibit telomerase, causing telomere shortening. In addition, ROS can induce telomeric single-strand DNA breaks (SSBs). The peroxired ...

Human shelterin protein POT1 prevents severe telomere instability induced by homology-directed DNA repair

Joachim Lingner, Anna-Sophia Briod

The evolutionarily conserved POT1 protein binds single-stranded G-rich telomeric DNA and has been implicated in contributing to telomeric DNA maintenance and the suppression of DNA damage checkpoint signaling. Here, we explore human POT1 function through g ...

The Gene-Regulatory Footprint of Aging Highlights Conserved Central Regulators

Johan Auwerx, Richardus Houtkooper, Maroun Bou Sleiman, Xu Wang, Pooja Jha

Many genes and pathways have been linked to aging, yet our understanding of underlying molecular mechanisms is still lacking. Here, we measure changes in the transcriptome, histone modifications, and DNA methylome in three metabolic tissues of adult and ag ...
