Cell Senescence: Controlling the senescence-associated secretory phenotype
Nature Reviews Molecular Cell Biology 17, 740 (2016). doi:10.1038/nrm.2016.157 Author: Paulina Strzyz Cell entry into senescence is typically irreversible and is associated with heterochromatization of the genome, which is marked by the establishment of senescence-associated heterochromatin foci (SAHF). However, in contrast to many genes that are silenced on senescence entry (including pro-proliferative genes), the expression of factors (Source: Nature Reviews Molecular Cell Biology)

DNA Repair: RNA –DNA hybrids: a double-edged sword in genomic stability
Nature Reviews Molecular Cell Biology 17, 740 (2016). doi:10.1038/nrm.2016.155 Author: Paulina Strzyz The formation of RNA–DNA hybrids results in replicative stress and, as a consequence, the emergence of DNA double-strand breaks (DSBs). Thus, RNA–DNA hybrid formation has been primarily associated with genomic instability. The findings of Ohle et al. now change this view, implicating RNA–DNA hybrids (Source: Nature Reviews Molecular Cell Biology)

The roles of RNA processing in translating genotype to phenotype
Nature Reviews Molecular Cell Biology 18, 102 (2017). doi:10.1038/nrm.2016.139 Authors: Kassie S. Manning & Thomas A. Cooper A goal of human genetics studies is to determine the mechanisms by which genetic variation produces phenotypic differences that affect human health. Efforts in this respect have previously focused on genetic variants that affect mRNA levels by altering epigenetic and transcriptional regulation. Recent studies show (Source: Nature Reviews Molecular Cell Biology)

Regulation of disease-associated gene expression in the 3D genome
Nature Reviews Molecular Cell Biology 17, 771 (2016). doi:10.1038/nrm.2016.138 Authors: Peter Hugo Lodewijk Krijger & Wouter de Laat Genetic variation associated with disease often appears in non-coding parts of the genome. Understanding the mechanisms by which this phenomenon leads to disease is necessary to translate results from genetic association studies to the clinic. Assigning function to this type of variation is notoriously difficult (Source: Nature Reviews Molecular Cell Biology)
