The activation of the transcription factor Hypoxia-inducible factor-1 (HIF-1) plays an essential role in tumor development, tumor progression and resistance to chemo- and radiotherapy. In order to identify compounds targeting the HIF pathway, a small-molecule library was screened using a luciferase-...

Animal germ cells employ small RNA-based mechanisms to recognize and silence DNA that invades their genome. One of these pathways is named the Piwi:piRNA pathway. Biogenesis of piRNAs is poorly understood. In C. elegans, the piRNA (21U-RNA)-binding Argonaute protein PRG-1 is the only known player ac...
