A Role for RNAi in the Selective Correction of DNA Methylation Defects
News Mar 20, 2009
It is now apparent that an understanding of epigentic mechanisms such as DNA methylation is essential to providing insights to the control of cell differentiation as well as the development of a number genetic diseases and cancer.
In a study published in science the authors describe a role for RNAi dependent mechanism in the protection of transgenerational loss of DNA methylation in Arabidopsis.

The international trade in elephant ivory has been illegal since 1989, yet African elephant numbers continue to decline. A study reports that DNA test results of ivory seizures made by law enforcement have linked multiple ivory shipments to the same network of dealers operating out of a handful of African ports.READ MORE
