The matrix metalloproteinase stromelysin-3 (ST3) has long been implicated to play an important role in cell fate determination during normal and pathological processes. Using the thyroid hormone-dependent Xenopus laevis metamorphosis as a model, we have previously shown that ST3 is required for apoptosis during intestinal remodeling and that laminin receptor (LR) is an in vivo substrate of ST3 ...

The cleavage of C−O linkages in aryl ethers biomass-derived lignin compounds without hydrogenation the aromatic rings is a major challenge for production sustainable mono-aromatics. Conventional strategies over heterogeneous metal catalysts require addition homogeneous base additives causing environmental problems. Herein, we propose Ru/C catalyst modified by Br atoms selective direct bonds dip...

The genomic RNA of pestiviruses is translated into a large polyprotein that is cleaved into a number of proteins. The structural proteins are N terminal in this polyprotein and include three glycoproteins called E0, E1, and E2 on the basis of the order in which they appear in the polyprotein. Using pulse-chase experiments, we show that a pestiviral glycoprotein precursor, E012, is formed that i...
