Research will be presented on Sunday, Dec. 15, during ASCB annual meeting in New Orleans Resolving a fundamental question in cell biology and showing off the powers of new high-resolution 3-D imaging, NIH scientists have discovered where the Golgi apparatus, which sorts newly synthesized proteins for transport inside and outside the cell, goes when it disassembles during cell division, according to research to be presented on Sunday, Dec. 15, at the American Association for Cell Biology...

Molecular microbiologists at the University of Southern California (USC) have uncovered intricate regulatory mechanisms within the cell that could lead to novel therapeutics for the treatment of cancer and other diseases. Their findings, which have long-standing significance in the basic understanding of cell biology, appear in the journal Nature Cell Biology. "Our research reveals a new regulatory mechanism that coordinates two distinct intracellular processes that are critical to...

Findings could provide basis for first treatment for Shiga toxin infection Carnegie Mellon University researchers have discovered that an element commonly found in nature might provide a way to neutralize the potentially lethal effects of a compound known as Shiga toxin. New results published in the Jan. 20 issue of Science by Carnegie Mellon biologists Adam Linstedt and Somshuvra Mukhopadhyay show that manganese completely protects against Shiga toxicosis in animal models. Produced by...

Sluggish recycling of a protein-slicing enzyme could promote Alzheimer's disease, according to a study published online on November 21 in The Journal of Cell Biology (www.jcb.org). Abeta, the toxic protein that accumulates in the brains of Alzheimer's patients, is formed when enzymes cut up its parental protein, known as amyloid precursor protein. One of those enzymes is beta-secretase or BACE1. BACE1 cycles between the Golgi apparatus and the plasma membrane, traveling through endosomes...

All life on earth is threatened by chaos. In this sense, a cell is like a ship which could at any moment sink in a sea of chaos. It must constantly consume energy to maintain the same level of order to avoid going under "“ metaphorically speaking, the infiltrating water of chaos needs to be pumped out, permanently. Scientists from the Max Planck Institute of Molecular Physiology in Dortmund have now discovered how cells ensure the correct distribution of proteins throughout their...

Location, location, location determines a protein's role Using a method they developed to watch moment to moment as they move a molecule to precise sites inside live human cells, Johns Hopkins scientists are closer to understanding why and how a protein at one location may signal division and growth, and the same protein at another location, death. Their research, published Feb. 14 in Nature Methods, expands on a more limited method using a chemical tool to move proteins inside of cells to...

EMBL discovery could yield evolutionary insights and new model organism Although they are present almost everywhere, on land and sea, a group of related bacteria in the superphylum Planctomycetes-Verrucomicrobia-Chlamydiae, or PVC, have remained in relative obscurity ever since they were first described about a decade ago. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have discovered that these poorly-studied bacteria possess proteins thought to exist...

A research team at the University of California, San Diego School of Medicine has provided a surprisingly simple explanation for the mechanism and features of the "Golgi apparatus" "“ a structure that has baffled generations of scientists. The model developed by the UC San Diego scientists suggests that the Golgi's unusual shape is a direct consequence of the way it works. Their study will be published in the October 16 issue of the journal Cell. The Golgi apparatus serves as a...

Scientists in New York and North Carolina are reporting assembly of the first functioning prototype of an artificial Golgi organelle. That key structure inside cells helps process and package hormones, enzymes, and other substances that allow the body to function normally. The lab-on-a-chip device could lead to a faster and safer method for producing heparin, the widely used anticoagulant or blood thinner, the researchers note. Their study is scheduled for the Aug. 12 issue of the Journal of...
