Genes

New model can isolate the effects of nutrients on gene expression and physiology

Posted February 17, 2014

Everyday our cells take in nutrients from food and convert them into the building blocks that make life possible. However, it has been challenging to pinpoint exactly how a single nutrient or vitamin changes gene expression and physiology. Scientists at the University of Massachusetts Medical School have developed a novel interspecies model system that allows these questions to be answered. In a study appearing in the journal Cell, UMMS researchers use this new approach to show how bacterially supplied vitamin B12 changes gene expression, development and fertility in the model organism C. elegans.

Relationship between Vitamin D Receptor gene polymorphisms and the components of metabolic syndrome

Posted July 16, 2013

The Vitamin D Receptor gene (VDR) is expressed in many tissues and modulates the expression of several other genes. The purpose of this study was to investigate the association between metabolic syndrome (MetSyn) with the presence of VDR 2228570 C > T and VDR 1544410 A > G polymorphisms in Brazilian adults.

Gene Activity In Stem Cells, Vitamin C And In Vitro Fertilization

Posted July 7, 2013

Vitamin C affects whether genes are switched on or off inside mouse stem cells, and may thereby play a previously unknown and fundamental role in helping to guide normal development in mice, humans and other animals, a scientific team led by UC San Francisco researchers has discovered.

Vitamin C Influences Gene Activity In Stem Cells

Posted July 3, 2013

A study of mouse stem cells reveals that vitamin C may play a role in their health by influencing the switching on and off of genes. The researchers suggest this could have an important effect on the development of mice, humans and other animals, and finding out more about the underlying mechanisms could improve our understanding of in vitro fertilization, cancer and adult stem cells.

Higher-Producing, Better-Tasting Chocolate Likely Following Genome Sequencing Of Cacao Plant

Posted June 5, 2013

The freshly sequenced genome of the most commonly cultivated cacao plant in the world is revealed in the open access journal Genome Biology. Researchers have utilised high quality DNA sequences to demonstrate the usefulness and quality of the sequence to identify genetic markers that can lead to higher yielding cocoa plants that still produce better tasting cocoa.
