Dead cells get the squeeze
acrophages can clean up the detritus of dying cells. But that, say Jody Rosenblatt, Martin Raff, and Louise Cramer (University College London, London, UK), is not the whole story. They have found that cells undergoing apoptosis in an epithelial sheet signal to their neighbors to begin squeezing, in a process that maintains the barrier function of the epithelium while extruding the dying cell. M...
متن کاملCrawling cells feel the squeeze
Y ou drive differently on narrow streets than you do on an open stretch of highway. Similarly, migrating cells rely on different movement mechanisms depending on whether they have ample space or are in cramped conditions, Hung et al. reveal (1). In the body, migrating cells usually must slither through spaces in the extracellular matrix or slip through narrow channels that run between connectiv...
متن کاملRNA Chaperones Exist and DEAD Box Proteins Get a Life
The RNA chaperone hypothesis suggests the existence of proteins that resolve misfolded RNA structures in vivo. A recent study has found an RNA-dependent ATPase that functions in this manner.
متن کاملComparative Study on the Ni2+ Biosorption Capacity and Properties of Living and Dead Pseudomonas putida Cells
Microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. In some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. Maintaining higher biosorption capability and understanding t...
متن کاملDevelopmental Patterning: Putting the Squeeze on Mis-specified Cells
Widely implicated in human disease, abnormal cellular cysts reflect dramatic defects in the maintenance of epithelial integrity. A new study reports that epithelial cysts may arise as a surprisingly general consequence of clonal defects in the specification of cell identity.
