Biologist offers WUSTL program as way to incorporate genomics into curricula (http://news-info.wustl.edu/news/page/normal/9775.html)

2007 -- The next generation of consumers will be the true beneficiaries of the promise of genomics. But how will they make informed choices in a world resplendent with genomics products, including tools to predict disease and the engineered drugs to treat those diseases?
The answer, says Sarah C.R. Elgin, Ph.D., WUSTL professor of biology in Arts & Sciences, is more genetics and genomics at every level of American education.

Biologists find pathway to gene silencing (http://news-info.wustl.edu/tips/page/normal/7538.html)
Sept. 7,
2006 --
Biologists at Washington University in St. Louis have made an important breakthrough in understanding a pathway plant cells take to silence unwanted or extra genes using short bits of RNA. Basically, they have made it possible to see where, and how, the events in the pathway unfold within the cell, and seeing is believing, as the old saying goes. Craig Pikaard, Ph.D., Washington University professor of biology in Arts & Sciences and his collaborators have described the roles that eight proteins in Arabidopsis plants play in a pathway that brings about DNA methylation, an epigenetic function that involves a chemical modification of cytosine, one of the four chemical subunits of DNA.

Eric Richards, Ph.D., professor of biology at Washington University in St. Louis, writing in the May issue of Nature Reviews Genetics, analyzes recent and past research in epigenetics and the history of evolution and proposes that epigenetics should be considered a form of soft inheritance, citing examples in both the plant and mammalian kingdoms.

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. Studying the phenomenon of nucleolar dominance, in which one parental set of ribosomal genes in a hybrid is silenced, Craig Pikaard, Ph.D., Washington University professor of biology in Arts & Sciences and colleagues have identified the protein HDA6 as an important player in the silencing.

At Washington University in St. Louis, teachers from five school districts are working with science and math education faculty in an effort designed to align curriculum to the NCLB standards and to improve instruction. Their work is supported by $6.5 million from the National Science Foundation, through funding from NCLB.
