The findings by a team of Massachusetts General Hospital (MGH) investigators, which will be published in the April 24 issue of Cell and are receiving advance online release, support the importance of epigenetics — processes controlling whether or not genes are expressed — in cancer pathology and identify molecular circuits that may be targeted by new therapeutic approaches.

Methylations are chemical changes that control gene activity, that is, whether they are active or not.

Of these, a high proportion are so - called command - and - control genes that help bacteria decide whether to form colonies or to continue seeking better shelter, possibly making Pseudomonas «smarter» than other bacteria.

Instead, the differences appear to be in the promoter regions for these genes, an area of DNA close to the gene that helps control whether it ultimately used to make protein.

Tapio, meanwhile, has adapted standard proteomics techniques so that they can be applied to some of the old tissues, and several groups are studying whether micro-RNAs — which help to control gene expression and are relatively stable — are present in the samples.

It's hard to say what is selecting for these traits, and to discern whether they are being passed down through the women's genes, but because Stearns controlled for many social and cultural factors, it is likely that his results document genetic, rather than cultural evolution at work.

Interestingly, the results of our promoter analysis for all these genes revealed that 9 of 17 genes (COL13A1, CSF3, FSCN1, HG18, LTBP1, PELI1, PLOD2, SCNN1A, and TNFSF10) have perfectly matched consensus sequences of KLF4 binding site on the promoter regions, suggesting a potential possibility of controlling these genes by KLF4 although it is not clear whether these genes are cause or consequence of brain metastasis at this point.

Using data from blood and brain tissue, a team led by researchers at Johns Hopkins Bloomberg School of Public Health found that they could gain insights into mechanisms that might help explain autism by analyzing the interplay between genes and chemical tags that control whether genes are used to make a protein, called epigenetic marks.

The current work shows that changes in the genetic code of a particular gene can control epigenetic marks at different genes, implying that a gene's genetic code can affect whether other genes are turned on and off, which makes it important to understand the function of all genes involved, not just the one with the so - called misspelling.

The researchers identified 24 potential reprogramming factors — proteins that control whether other genes in the cell are turned on or off.

Gene Set Enrichment Analysis (GSEA) is a microarray data - mining technique used to determine whether there is coordinated differential expression or «enrichment» in a set of functionally related genes when comparing control and experimental samples [35].
