08/2017 - RNA polymerase I, bending the rules?

Transcription initiation is one of the key regulatory steps in expressing the genetic information encoded in the DNA. Mechanisms of RNA Pol II transcription have been extensively studied, whereas the structural basis of RNA Pol I and III transcription is still poorly defined. Three recent studies discussed here give a first glimpse into the molecular mechanisms underlying the process of RNA Pol I transcriptional initiation and […]

07/2017 - Switching dynein motors on and off

Cytoplasmic dyneins transport cellular components from the periphery toward the center of the cell. By moving cargoes along microtubules, dyneins ensure proper cell division, regulate exchange of materials between organelles, and contribute to the internal organization of eukaryotic cells. Two recent studies show that, upon dimerization, cytoplasmic dyneins intrinsically adopt an autoinhibited configuration that can […]

05/2017 - Single-cell transcriptomics uncovers distinct molecular signatures of stem cells in chronic myeloid leukemia

Recent advances in single-cell transcriptomics are ideally placed to unravel intratumoral heterogeneity and selective resistance of cancer stem cell (SC) subpopulations to molecularly targeted cancer therapies. However, current single-cell RNA-sequencing approaches lack the sensitivity required to reliably detect somatic mutations. We developed a method that combines high-sensitivity mutation detection with whole-transcriptome analysis of the same […]

05/2017 - BLISS is a versatile and quantitative method for genome-wide profiling of DNA double-strand breaks

Precisely measuring the location and frequency of DNA double-strand breaks (DSBs) along the genome is instrumental to understanding genomic fragility, but current methods are limited in versatility, sensitivity or practicality. Here we present Breaks Labeling In Situ and Sequencing (BLISS), featuring the following: (1) direct labelling of DSBs in fixed cells or tissue sections on […]
