Scientists prove that parts of cell nuclei are not arranged at random

Transcription Factors Chromatin Splicing Factors (Evolution Research: John Latter / Jorolat)The nucleus of a mammal cell is made up of component parts arranged in a pattern which can be predicted statistically, says new research published today. Scientists hope this discovery that parts of the inside of a cell nucleus are not arranged at random will give greater insight into how cells work and could eventually lead to a greater understanding of how they become dysfunctional in diseases like cancer.

The study, published today in PLoS Computational Biology, involved systems biologists working together with mathematicians to identify, for the first time, 'spatial relationships' governing the distribution of an important control protein in the nucleus, in relation to other components within the nuclei of mammal cells.

This widespread protein called CBP acts on certain genes within the cell nucleus, turning them on to make specific proteins at different times throughout the life of the cell.
