In today's issue of Science:
A team led by Wistar Institute scientists publish on the process of microRNA editing and demonstrate in mice that edited miRNAs silence different targets than their original forms.
In a paper from lead author Qian-Hua Shen at the Max-Planck Institute, researchers describe plant defense mechanisms, which they show to be taking place on the gene transcript level. The defense is a response to pathogen invasion and in this study is demonstrated in barley.
From Mass General comes a paper on DNA methylation, with a specific focus on methylation that occurs on the X chromosome. The authors performed a large-scale analysis to better understand the relationship between methylation, CpG island locations, and expression.
