Our latest paper on the length distribution of simple tandem repeats in mammalian genomes is out in Nature Communications. All credit go to my brilliant collaborators Ryan McGinty, Daniel Balick and Shamil Sunyaev! rdcu.be/eXGyo
Inherent instability of simple DNA repeats shapes an evolutionarily stable distribution of repeat lengths
Nature Communications - Repetitive DNA sequences shape genome evolution and instability. Here, the authors analyze repeat length distributions across over 300 mammals and show that long repeats...

The origin of mirror repeats in the human genome
Abstract. Mirror DNA repeats were found in genomic DNA several decades ago, but their role and the mechanisms leading to their abundance have remained a my

My fantastic undergraduates at Stand up for Science rally in Boston today!
What RNA polymerase gets up to in the genome and how mutations happen! Just out in Nature! Many thanks to many collaborators & congrats 1st author Jingjing Liu! www.nature.com/articles/s41...
Already bruised by the Trump administration’s first round of firings of federal workers, employees at NIH faced more bad news. NIH’s 27 institute directors were told this week that the agency must cut staffing back to 2019 levels, or at least 10% below its 2024 tally. scim.ag/3EP8gjy
More NIH job cuts coming? Agency's scientists already reeling after week of firings
NIH is appealing loss of some lab leaders among in-house research program while bracing for the next actions from the Trump administration

Best holiday present: Our comprehensive review of triplex H-DNA has just come out in NAR Mol Medicine. I am indebted to two outstanding graduate students: Julia Hisey and Chiara Masnovo, whose enthusiasm, dedication and hard work made this review possible! academic.oup.com/narmolmed/ad...
Triplex H-DNA structure: the long and winding road from the discovery to its role in human disease
Abstract. H-DNA is an intramolecular DNA triplex formed by homopurine/homopyrimidine mirror repeats. Since its discovery, the field has advanced from chara

Another week, another great paper! Kudos to the amazing grad student, Chiara Masnovo who single-handedly initiated and led the project, and arranged a terrific collaboration with the Aharoni lab from Ben-Gurion University, and to the great members of the two labs. www.nature.com/articles/s41...?
Stabilization of expandable DNA repeats by the replication factor Mcm10 promotes cell viability - Nature Communications
DNA repeats can lengthen or shorten during their replication, which may lead to a human disease. Here, the authors discovered that an essential replication protein, Mcm10, counteracts instability of G...
