Interactions between the genome and the nuclear lamina are multivalent and cooperative.

Lamina-associated domains (LADs) are megabase-sized genomic regions that interact with the nuclear lamina (NL). It is not yet understood how their interactions with the NL are encoded in their DNA. Here we designed an efficient LAD 'scrambling' approach, based on transposon-mediated local hopping of loxP recombination sites, to generate series of large deletions and inversions that span LADs and flanking sequences.

Aquarius helicase facilitates HIV-1 integration into R-loop enriched genomic regions.

HIV-1 integration into host chromosomes, essential for viral replication, is catalysed by viral integrase (IN). IN recurrently targets intronic regions of transcriptionally active genes, but a detailed understanding of this process is still unclear. Here, using ex vivo activated human primary CD4T cells, we find that genomic RNA:DNA hybrids (R-loops) preferentially map to intronic regions of active genes that are typical HIV-1 integration sites.

Understanding and reversing mammary tumor-driven reprogramming of myelopoiesis to reduce metastatic spread.

Tumor-induced systemic accumulation and polarization of neutrophils to an immunosuppressive phenotype is a potent driver of metastasis formation. Yet, how mammary tumors reprogram granulopoiesis at the molecular level and when tumor imprinting occurs during neutrophil development remains underexplored. Here, we combined single-cell, chromatin and functional analyses to unravel the tumor-driven reprogramming of granulopoiesis in the bone marrow, along with intervention studies aimed at reversing this process.

Taxanes trigger cancer cell killing in vivo by inducing non-canonical T cell cytotoxicity.

Although treatment with taxanes does not always lead to clinical benefit, all patients are at risk of their detrimental side effects such as peripheral neuropathy. Understanding the in vivo mode of action of taxanes can help design improved treatment regimens. Here, we demonstrate that in vivo, taxanes directly trigger T cells to selectively kill cancer cells in a non-canonical, T cell receptor-independent manner.
