Genome-wide identification of RETINOBLASTOMA RELATED 1 binding sites in Arabidopsis reveals novel DNA damage regulators

The human Retinoblastoma (pRb) tumor suppressor is a key cell cycle regulator with homologs in most eukaryotes. Here, Bouyer, Heese et al describe a genome-wide DNA-binding study of the Arabidopsis pRb homolog RBR1. The authors find that RBR1 binds to roughly 1000 genes and 500 transposons, and identify new genes necessary for growth upon DNA damage.

Downregulation of ERG and FLI1 expression in endothelial cells triggers endothelial-to-mesenchymal transition

During endothelial-to-mesenchymal transition (EndMT), endothelial cells lose their characteristics and acquire mesenchymal-like properties. Here, Nagai and colleagues show that reduced expression of ERG and FLI1 trigger EndMT. They also find that ERG and FLI1 expression is downregulated in tumors, suggesting EndMT is triggered in the tumor microenvironment.

Amino acid residues in five separate HLA genes can explain most of the known associations between the MHC and primary biliary cholangitis

Here, Darlay et al use dense single nucleotide polymorphism (SNP) data to investigate the underlying causes of Primary Biliary Cholangitis (PBC). The authors show that associations between PBC and variants in the human leukocyte antigen (HLA) gene can be largely explained by variation at five amino acid positions.

Anisotropic Crb accumulation, modulated by Src42A, is coupled to polarised epithelial tube growth in Drosophila

Here, Olivares-Castiñeira and Llimargas use the Drosophila tracheal system as a model to investigate the mechanisms underlying size regulation of tubular organs. They find that Src42A is required for anisotropic accumulation of Crumbs during tube elongation, providing new insights into how organ growth is controlled.

A suppressor of a wtf poison-antidote meiotic driver acts via mimicry of the driver’s antidote

Meiotic drivers are selfish alleles that subvert gametogenesis to increase their transmission into progeny. Here, Bravo Núñez et al find that an additional wtf gene, wtf13, found in intensely studied lab strains, is also a meiotic driver. The authors further find that this driver is only capable of driving in the absence of wtf18-2, which mimics the antidote of wtf13.

The many fates of tissue regeneration

Abdullah and Duronio comment on work by Verghese and Su, who show that stem-cell–like behavior can be induced in Drosophila cells in response to tissue damage resulting from ionizing radiation.

Selfish genetic elements

Ågren and Clark discuss selfish genetic elements: once dismissed as genetic curiosities, with little relevance for evolution, they are now recognized to affect a wide swath of biological processes. This article was also published as a live page on Wikipedia.
