The 8th International Symposium on Mutations in the Genome covered a broad range of technological developments and their applications to detecting genomic sequence variation.
A new study of mice lacking Prox1, a gene required for the formation of lymphatic endothelial cells, unveils a link between lymph fluid and fat deposition. These findings bring the lymphatic vascular system into the focus of obesity research.
Transcription-coupled nucleosome turnover provides an opportunity to incorporate new nucleosomes at active genes. Swapping nucleosomes that contain silencing marks with those that are more permissive for transcription may provide a mechanism for remembering the activity state of a gene through the cell cycle.
Cancer metastasis has historically been viewed in the context of the mutational spectra arising during development of the primary cancer. The identification of a new modifier of cancer metastasis efficiency in mice provides experimental support for a predisposition model in which metastatic potential is viewed as a heritable trait influenced by host genetic polymorphisms.
Asymmetric division of stem cells results into two unequal daughter cells, only one of which resembles the parent stem cell. A new study provides genetic evidence in Drosophila melanogaster that the disturbance of this delicately balanced process in neuronal stem cells induces a cancer-like state.
The ability of crop plants to tolerate high salt concentrations is an agriculturally useful trait. A new study in rice shows that allelic variation in OsHKT8, which encodes a Na+ transporter, contributes to the enhanced capacity of a salt-tolerant variety to maintain shoot K+ homeostasis under NaCl stress.
