    Genome-wide mapping of native co-localized G4s and R-loops in living cells

    Ting Liu, Xing Shen ... Zhihong Xue
    The newly developed antibody-free techniques, HepG4-seq for G-quadruplexes and HBD-seq for R-loops, robustly reveal the comprehensive maps of native G-quadruplexes and R-loops, as well as their roles in transcriptional regulation.

    Control of the polyamine biosynthesis pathway by G2-quadruplexes

    Helen Louise Lightfoot, Timo Hagen ... Jonathan Hall
    An ensemble of conserved G2-quadruplex structures in the untranslated regions of messenger RNAs from genes in the polyamine bioysynthesis pathway sense polyamine levels and regulate polyamine synthesis in cells.

    The C9ORF72 GGGGCC expansion forms RNA G-quadruplex inclusions and sequesters hnRNP H to disrupt splicing in ALS brains

    Erin G Conlon, Lei Lu ... James L Manley
    The C9orf72 expansion binds and sequesters the splicing factor hnRNP H leading to insoluble G-quadruplex aggregates that functionally reduce hnRNP H, thereby producing splicing defects.

    Unleashing a novel function of Endonuclease G in mitochondrial genome instability

    Sumedha Dahal, Humaira Siddiqua ... Sathees C Raghavan
    A new role for Endonuclease G with respect to the generation of mtDNA deletions is identified, which is dependent on the formation of G4 DNA within human mitochondria.
