... Apart from A. thaliana, genetic data are available for two other species within the Brassicaceae family. In Brassica rapa it was shown that two traits, glabrous and yellow seeds, strictly co-segregated and that these two traits map to the BrTTG1 locus [38]. In addition a yellow seed mutation was map ...

... Non-invasive cancers stay within the milk ducts or milk lobules in the breast. They do not grow into or invade normal tissues within or beyond the breast. Non-invasive cancers are sometimes called in situ or pre-cancers. If the cancer has grown into normal tissues, it is called invasive. Most breast ...

Early Light Inducible Protein (ELIP) was first identified as a protein that was transiently induced in the very early stages of the greening process in etiolated pea seedlings (a 24 000-Mr precursor protein (Meyer & Kloppstech 1984)). ELIP is a stress-related protein and belongs to the CAB superfami ...

Polycomb Group Proteins and Cancer

The Polycomb-group proteins (PcGs) are a family of proteins that use epigenetic mechanisms to maintain or repress expression of their target genes. They were originally discovered in Drosophila (fruit flies), though they've been shown to be conserved in many species due to their vital roles in embryonic development. These proteins' ability to alter gene expression has made them targets of investigation for research groups seeking to understand disease pathology and oncology.
