Scientists shed light on evolution of gene regulation

Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes.

Researchers find new mode of gene regulation in mammals

Researchers at the University of California, Santa Cruz, have discovered a type of gene regulation never before observed in mammals--a "ribozyme" that controls the activity of an important family of genes in several different species.

New targets for RNAs that regulate genes

Tiny strands of genetic material called RNA – a chemical cousin of DNA – are emerging as major players in gene regulation, the process inside cells that drives all biology and that scientists seek to control in order to fight disease.

Correlation studies confirm quality of Genomatix Promoter Annotations

Genomatix Software GmbH, a Systems Biology company focussed on high quality annotation and the understanding of gene regulation, has begun showcasing its abilities in the analysis of data generated by Next Generation Sequencing (NGS) technology.

New details of gene-regulatory network governing metabolism

Metabolism is a central feature of life – a myriad of biochemical processes that, together, enable organisms to nourish and sustain themselves. Scientists at Cold Spring Harbor Laboratory (CSHL) are in the forefront of efforts to demonstrate how the regulation of genes governs fundamental life processes, including metabolism.

Free shopping in virtual bazaar of gene regulation data

An international team has opened a virtual bazaar, called PAZAR, which allows biologists to share information about gene regulation through individually managed 'boutiques' (data collections).

Importance of gene regulation for common human disease

harminka — Sun, 16 Sep 2007 15:05:55 -0500

A new study published in Nature Genetics on Sunday 16 September 2007 show that common, complex diseases are more likely to be due to genetic variation in regions that control activity of genes, rather than in the regions that specify the protein code.

Gene regulation in humans is closer than

Gene networks are some of the most basic features of a living organism. An external or internal stimulus activates some genes, which in turn control others genes whose activity turns on or off various biological processes (such as the cell cycle, energy production, DNA repair, cellular suicide etc).

Mechanism by which transcription factor controls gene expression

The Conaway Lab — led by Joan Conaway, Ph.D., and Ron Conaway, Ph.D., Investigators — has published findings that shed light on the role of the much-studied transcription factor YY1 in gene expression. Yong Cai, Ph.D., Research Specialist I, and Jingji Jin, Ph.D., Senior Research Associate, are the paper’s coequal first authors.

Unravelling new complexity in genome

A major surprise emerging from genome sequencing projects is that humans have a comparable number of protein-coding genes as significantly less complex organisms such as the minute nematode worm Caenorhabditis elegans. Clearly something other than gene count is behind the genetic differences between simpler and more complex life forms.

Gene regulation, not just genes, is what sets humans apart

The striking differences between humans and chimps aren’t so much in the genes we have, which are 99 percent the same, but in the way those genes are used, according to new research from a Duke University team.
