Scientists Clarify a Mechanism of Epigenetic Inheritance
Although letters representing the three billion pairs of molecules that form the "rungs" of the helical DNA "ladder" are routinely called the human "genetic code," the DNA they comprise transmits traits across generations in a variety of ways, not all of which depend on the sequence of letters in the code. view more (2008-04-23)
New Method Developed by UC San Diego Bioengineers Gives Regenerative Medicine a Boost
Bioengineers at UC San Diego have developed a breakthrough method for sequencing-based methylation profiling, which could help fuel personalized regenerative medicine and even lead to more efficient and cost-effective methods for studying certain diseases. view more (2009-04-24)
Epigenetic research uncovers new targets for modification enzymes
Enzymes regulating genetic expression can be just as important as the genome itself, increasing evidence shows. The expanding field of epigenetics focuses on the multiple influences on DNA and surrounding molecules that determine whether genes are turned on or off during development and disease processes. view more (2008-04-28)
Genetic double-agents unmasked
Babraham Institute and Cancer Research UK scientists have discovered that certain enzymes with a key activity in the immune system may be important in stem-cell development, but may also work against us by contributing to the occurrence of cancer. view more (2004-10-26)
Epigenetics to shape stem cell future
Everyone hopes that one day stem cell-based regenerative medicine will help repair diseased tissue. view more (2007-02-20)
Researchers find protein that silences genes
A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off - in this case, the turning off of thousands of nearly identical genes in a hybrid plant. view more (2006-05-08)
Evolutionarily preserved mechanism governs use of genes
Researchers at Uppsala University have found that the protein coding parts of a gene are packed in special nucleosomes. The same type of packaging is found in the roundworm C elegans, which is a primeval relative of humans. view more (2009-08-18)
USC study in Nature Genetics supports a stem cell origin of cancer
Researchers at the University of Southern California (USC) recently made significant strides toward settling a decades-old debate centering on the role played by stem cells in cancer development. view more (2007-01-10)
Turn-ons and turn-offs for neurons
Our brain consists of billions of nerve cells enabling to learn, remember and reason. Every time we think and experience, touch, smell or fear, millions of neurons in our brain becomes active. view more (2007-06-20)
Regulating the Nuclear Architecture of the Cell
An organelle called the nucleolus resides deep within the cell nucleus and performs one of the cell's most critical functions: it manufactures ribosomes, the molecular machines that convert the genetic information carried by messenger RNA into proteins that do the work of life. view more (2006-12-11)
Scientists find clue to mechanisms of gene signaling and regulation
Scientists have discovered a pattern in the DNA sequence of the mouse genome that may play a fundamental part in the way DNA molecules regulate gene expression. view more (2007-08-23)
Silenced genes as a warning sign of blood cancer
In many types of cancer, parts of the genetic material of tumor cells are switched off by chemical labels called methyl groups. This kind of methyl labeling ranges among the epigenetic changes that do not change the sequence of DNA building blocks. view more (2009-08-05)
Growth of new brain cells requires 'epigenetic' switch
New cells are born every day in the brain's hippocampus, but what controls this birth has remained a mystery. Reporting in the January 1 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that the birth of new cells, which depends on brain activity, also depends on a protein that is involved in... view more...

'Destruct' triggers may be jammed in tumor cells, UF geneticists say
Tumor cells living in the cross hairs of radiation or chemotherapy may be able to escape death because their self-destruct mechanisms are jammed, say University of Florida scientists writing in a recent issue of Developmental Cell. view more (2008-05-01)
Duke scientists map imprinted genes in human genome
Scientists at Duke University have created the first map of imprinted genes throughout the human genome, and they say a modern-day Rosetta stone - a form of artificial intelligence called machine learning - was the key to their success. view more (2007-11-30)
CSHL researchers map changing epigenetic modifications that enable transposons to run amok
Much like cancer cells, plant cells grown for a long time outside of their normal milieu, in culture dishes, have highly unstable genomes. view more (2008-12-11)
New view of cancer: 'Epigenetic' changes come before mutations
A Johns Hopkins researcher, with colleagues in Sweden and at the Fred Hutchinson Cancer Research Center, suggests that the traditional view of cancer as a group of diseases with markedly different biological properties arising from a series of alterations within a cell's nuclear DNA may have to give way to a more complicated view. view more (2005-12-22)
Liposuctioned fat stem cells to repair bodies
Expanding waistlines, unsightly bulges: people will gladly remove excess body fat to improve their looks. But unwanted fat also contains stem cells with the potential to repair defects and heal injuries in the body. view more (2007-02-23)
Enzyme complex thought to promote cancer development can also help prevent it
In a case of basic science detective work, researchers at The University of Texas M. D. Anderson Cancer Center have solved the puzzle of the "inconsistent biomarker" and, in the process, may have discovered an agent that can suppress cancer development. view more (2005-10-14)
