The benefits of fruit and vegetable consumption are not a new discovery. However, new research confirms their role in reducing mortality…
In the current issue of PLoS Genetics, Michigan State University genetic scientists have begun to understand how the rest of the genome interacts with such mutations to cause the differences we see among individuals. "It’s been known for a while that genetic mutations can modify each other’s effects," said Ian Dworkin, MSU associate professor of zoology and co-author of the paper. "And we also know that the subtle differences in an individual’s genome — what scientists call wild type genetic background — also affects how mutations are manifested." Dworkin and Sudarshan Chari, zoology doctoral student and the paper’s lead author, wanted to know how common it was for wild type genetic background to alter the way genetic mutations interact with each other. …
Stowers Institute for Medical Research Associate Investigator Matt Gibson, Ph.D., and his team use simple animal systems like fruit flies and sea anemones to investigate how epithelial cells maintain order while getting jostled by cell division. New findings from his lab published in the July 21 advance online issue of Nature demonstrate that the way the mitotic spindle — the machinery that separates chromosomes into daughter cells during cell division — aligns relative to the surface of the cell layer is essential for the maintenance of epithelial integrity. It also hints at a surprising way that cells initiate a gene expression program seen in invasive cancers when that process goes awry. The study employs live imaging of fruit fly imaginal discs, simple larval tissues that ultimately give rise to the adult wing…
