Genomic Instability Profiles at the Single Cell Level in Mouse Colorectal Cancers of Defined Genotypes

Jörg Hülsken, Maxim Norkin

The genomes of many human CRCs have been sequenced, revealing a large number of genetic alterations. However, the molecular mechanisms underlying the accumulation of these alterations are still being debated. In this study, we examined colorectal tumours t ...

Seascape genomics reveals candidate molecular targets of heat stress adaptation in three coral species

Stéphane Joost, Oliver Michele Selmoni

Anomalous heat waves are causing a major decline of hard corals around the world and threatening the persistence of coral reefs. There are, however, reefs that have been exposed to recurrent thermal stress over the years and whose corals appear to have bee ...

Induction of a chromatin boundary in vivo upon insertion of a tad border

Denis Duboule, Lucille Delisle, Christopher Chase Bolt

Author summary During development, enhancer sequences tightly regulate the spatio-temporal expression of target genes often located hundreds of kilobases away. This complex process is made possible by the folding of chromatin into domains, which are separa ...
