Chromatin packages a few meters of DNA into a nucleus measuring a few microns. This tight folding occurs by assembling DNA with histones into so-called nucleosomes, thus ensuring the mechanical stability of our genome. On the flipside, this makes nucleosomes a formidable obstacle to the machines that read, copy or repair its DNA message. One of the fundamental questions in biology is to understand ...

DNA double strand breaks (DSBs) and telomeres both represent ends of a linear chromosome, and both can lead to dangerous genomic rearrangements. Recent studies in budding yeast suggest that persistent DSBs associate with factors in two perinuclear compartments, at nuclear pores and in the inner nuclear membrane (INM). The stability of short telomeres also involves telomere binding to an INM protei ...

Elucidation of a microRNA turnover machinery in C. elegans (miRT)

Start date: Mar 1, 2008, End date: Feb 28, 2010,

MicroRNAs (miRNAs) are a large class of noncoding regulatory RNAs. In animals miRNAs base-pair with the 3’ untranslated region (UTR) of their target mRNAs to target them for cleavage or translational repression. Repressed target mRNAs accumulate in cytoplasmic structures termed P-bodies, where some targets may be degraded. Other targets appear to be stable and can subsequently be re-expressed. In ...
