Controlled depolymerisation, as assessed by analytical ultracentrifugation, of low molecular weight chitosan for potential use in archaeological conservation [PDF]
, 2018 The heterogeneity and molecular weight of a chitosan of low molecular weight (molar mass) and low degree of acetylation (0.1), for potential use as a consolidant for decayed archaeological wood, has been examined by sedimentation velocity and ...

FEBS Letters, EarlyView.Most MmpLs transport lipids and glycolipids of the complex mycomembrane of mycobacteria. This study shows that MmpL10 from Mycobacterium smegmatis, the transporter of the trehalose polyphosphate precursor, harbors a coiled‐coil‐like extension. Biochemical and electron microscopy studies demonstrate that the coiled‐coil enables MmpL10 to trimerize.

ROCK signaling promotes collagen remodeling to facilitate invasive pancreatic ductal adenocarcinoma tumor cell growth [PDF]
, 2017 Pancreatic ductal adenocarcinoma (PDAC) is a major cause of cancer death; identifying PDAC enablers may reveal potential therapeutic targets. Expression of the actomyosin regulatory ROCK1 and ROCK2 kinases increased with tumor progression in human and ...
