Not exact matches

Using clinical, genetic, and gene expression data as filters to distinguish genes whose copy number alteration causes cancer from those for whom copy number changes are incidental, the team whittled down their list from 14,000 to a more manageable number, each of which they systematically tested using genetic experiments in animals.

Gene moonlighting can occur merely through changes in expression, which may result from as little as a single mutation; it does not require the meandering process of random alteration and selection implied by the duplication and neofunctionalization model.

This observation is further supported by the fact that studying alterations in the expression of genes also made it possible to identify persons whose levels of interleukin 6, an inflammation marker, were reduced as their serum vitamin D levels increased.

Compared with the ancestral lineage, the East African cichlid genomes possess: an excess of gene duplications; alterations in regulatory, non-protein-coding elements in the genome; accelerated evolution of protein - coding elements, especially in genes for pigmentation; and other distinct features that affect gene expression, such as insertions of transposable elements and regulation by novel microRNAs.

Because DDX3 exhibits tumor suppressor functions, such as a growth - suppressive property and transcriptional activation of the p21waf1 / cip1 promoter, and is inactivated through down - regulation of gene expression or alteration of subcellular localization in tumor cells, all these features together suggest that DDX3 might be a candidate tumor suppressor.

Changes in an epigenetic mechanism that turns expression of genes on and off may be as important as genetic alterations in causing pediatric acute lymphoblastic leukemia (ALL), according to a study led by scientists at St. Jude Children's Research Hospital and published in the June 10 online edition of the Journal of Clinical Investigation.

We examine alterations in biological stress regulatory systems; alterations in the neural regulation of stress responses; and expression of genes related to stress responses, both as latent indicators of impending health risks and as indicators of psychological and biological stress - reactive processes that may accelerate those risks.
