Genome Integrity Lab | @CRI_UTSW @UTSWMedCenter. We study how mitotic errors and genomic instability drive cancer evolution.

Dallas, TX
Excited to share our latest paper, out today @CellCellPress. We found that large pieces of the human genome can transfer between cells upon direct contact, endowing recipient cells with heritable phenotypic changes. (1/7) cell.com/cell/fulltext/S0092…

😊 New preprint! In budding yeast, Dna2-intrinsic condensation regulates long-range DNA-end resection. Analyses suggest redistribution of condensate grammar in humans. Congrats to Chris Jordan and the Mekhail, Wyatt, Cowen & Hakem labs! More to come soon. biorxiv.org/content/10.64898…

A big week for the lab! Two new papers on how cells repair DNA double-strand breaks: one on getting NHEJ started in chromatin, one on processing the ends before ligation. Years of work by a fantastic team.

How are mitotic chromosomes built? 🏗️ Our Review @TrendsGenetics revisits the classical chromosome scaffold model and connects it to condensins, topoIIα, and physical forces. We propose interphase chromatin domains as “building blocks”🧩of chromosomes: authors.elsevier.com/a/1nmwr…

🎉 Excited to share the first preprint from the Panday Lab! biorxiv.org/content/10.64898… We identify FANCM as an adaptive genome-maintenance dependency in BRCA1-deficient breast cancer and uncover its role in restraining ongoing structural genome evolution.

How did we come to understand cancer in the light of evolutionary theory? Nothing makes sense if not with population genetics! In our latest @NatureRevCancer review we unpack how population genetics theory applied to somatic cells allows us to measure and predict cancer evolution from molecular data. Computational modelling in oncology has gone a long way but we need to go much further. The frontier is combining evolutionary theory with machine learning. Link below👇

1/ Out today in @Nature! 🧵 We mapped the mutational processes shaping 959 prostate cancer genomes from the Pan Prostate Cancer Group (PPCG), integrating SBS, ID, CX and complex SV signatures. Eight footprints account for the processes in 85% of cases nature.com/articles/s41586-0…

Is euchromatin really “open”? 🧬 Using super-resolution imaging🔬 our new study @NatureGenet reveals: Euchromatin forms condensed domains in live cells. Cohesin constrains them and prevents domain mixing for proper transcriptional insulation🚧 🔗nature.com/articles/s41588-0… (1/2)

Out in @ScienceMagazine: we found a new asymmetry in large-scale chromosome structure: sister chromatids are shifted by hundreds of kb in the 5′→3′ direction of their inherited strands! A close collaboration w/ @Gerlich_Lab, led by @flavia_corsi science.org/doi/10.1126/scie…

Mitotic #genomes have their #chromosomes connected together by #DNA-based linkers with about the same spring constant as the chromos themselves biorxiv.org/content/10.64898… [also the case for 🐁 meiotic metaphase] TY for a great collaboration, Lisa Hua Lab @SSUbiology !

In a new Science study, researchers show that chromatin exists as a hydrogel that undergoes a volume phase transition between condensed and uncondensed states that correspond to regions of gene activity and silence, respectively. Learn more in a new #SciencePerspective: scim.ag/4x2vkRX
