whether an animal was high, middle or low ranking with 80%accuracy, on the basis of gene expression alone.

when other animals entered the group showed that their gene expression responded rapidly, and predictably, to match their new status."It suggests a lot of plasticity in our gene expression response to our social environment,

which is an optimistic note, says Tung. It was known already that social status can change which genes get turned on and off in insects and fish,

"Clearly, changing ranks leads to changes in gene expression and not the other way around, he says. The macaque study suggests potential mechanisms for the Whitehall study's findings,

Gene families, cell-signalling networks and patterns of gene expression in comb jellies support ancient origins as well.

and gene expression associated with the Mets . Thus this new study shows even greater potential such that by normalizing oxidative inflammatory response

In this case no chemotherapy drug had been added Treatment with the flavonoid also modified gene expression. Certain genes associated with pro-inflammatory cytokines were highly upregulated de Mejia said.

Therefore dominant males were both masculinised and defeminised in terms of their gene expression. A male s attractiveness is a function of how they express their genes rather than the genes themselves.

or submissive but suspect that the concentration of male hormones or androgens may play a role in gene expression.

#Study of gene expression has revealed first steps of evolution in gene regulation in micea study of gene expression led by scientists at the EMBL-European Bioinformatics Institute (EMBL-EBI)

The team studied gene expression in five very closely related mouse species in order to pinpoint changes at the very earliest stages of evolution.

We found that parasitized bees were attacked not by their nestmates suggesting that they leave the hive voluntarily perhaps in response to the changes in gene expression in their brains.

Transcription is the first step of gene expression when DNA is copied. In this process the cell produces MESSENGER RNA that copies the genetic information from the cell nucleus to serve as a template for protein synthesis

Gene expression profiling combined with an understanding of the plants'biology allows researchers to understand how genes interact to create complex phenotypes said Neelima Sinha professor of plant biology at UC Davis

What they knew from a prior study is that the gene expression in pollen tubes that had grown through a pistil was much different than that of pollen tubes grown in the lab. Leydon's first step

therefore was to see which regulators of gene expression or transcription factors were at work in pistil-grown pollen tubes but not in the lab-grown ones.

what happens in Arabidopsis after ethylene gas causes activation of EIN3 a master transcription factor--a protein that controls gene expression--that Ecker had discovered

Not all genes targeted by EIN3 have changes in their gene expression Ecker says. They found that thousands of genes in the plant responded to EIN3.

To regulate plant growth plants need to perceive cytokinins and convert this information into changes in gene expression.

The KMDS target a key group of cytokinin-regulated transcription factors for destruction thereby regulating the gene expression changes that occur in response to cytokinin.

This approach is known as gene expression profiling and by studying the expression profiles of 2000 human breast tumors Miller

while low immune gene expression predicted for a high likelihood of cancer recurrence. An important next step Miller said will be translating this into a diagnostic test that may help doctors make more informed treatment decisions.

However the modern strategy of breeding for hybrid vigor has been accompanied by marked changes in patterns of gene expression.

Multiple types of RNA polymerases are responsible for setting gene expression in motion in all cells and Pol IV is an enigmatic RNA polymerase that is known in plants to produce small RNA molecules.

Comparing transcriptomes across ranges will reveal new changes in gene expression in the highly successful invasive population.

and therefore early rapid and robust detective methods are required especially presymptomatic diagnosis. The study's author Dr Hailing Jin of The University of California Riverside explains srnas are important gene expression modulators some

The binding leads to suppression of gene expression. Known as RNA gene silencing this suppression plays an important role in regulating plant growth and development.

Weeds influence gene expression, growth in cornthe axiom growing like a weed takes on new meaning in light of changes in gene expression that occur

In short these changes in gene expression adversely affect the plant's ability to grow and reproduce.

when the corn had as few as two and four leaves they still saw differences in gene expression

These changes in gene expression can help explain instances in which the yield is unaffected but a slight reduction has taken place in the plant

Next the researchers look at the effect of water stress on gene expression using corn planted on high and low ground.

The three-year study included cell culture studies at Rice as well as a detailed analysis of gene expression profiles of more than 500 patients from the Cancer Genome Atlas and protein-expression profiles from about 200

What got us interested in this is the whole question of how the environment--including a person's diet--influences gene expression said Tosi.

which leads to unfit gene expression with age. Developing Nutraceuticals That Can Extend Mean and Maximum Lifespan

then one possible anti-aging strategy is to utilize wide-spectrum nutraceuticals to modify gene expression to a state consistent with greater longevity.

Note that the ideal gene expression pattern is not identical to youthful gene expression as some of the youthful gene expression is inconsistent with longevity (e g. genes promoting rapid growth that can lead to cancer.

To develop potential wide-spectrum antiaging nutraceuticals, Genescient initially set out to identify nutraceutical compounds that would target as many of the complementary longevity pathways as possible
