Link between a key molecular player and human chromosomal birth defects established

Using yeast genetics and a novel scheme to selectively remove a single protein from the cell division process called meiosis, a cell biologist at The Florida State University found that when a key molecular player known as Pds5 goes missing, chromosomes fail to segregate and pair up properly, and birth defects such as Down syndrome can result.

Disruption of the spectrin-actin network leads to lens cell in the eye to lose their shape: Study

A network of proteins underlying the plasma membrane keeps epithelial cells in shape and maintains their orderly hexagonal packing in the mouse lens, say Nowak et al. The study will appear in the September 21, 2009 issue of the Journal of Cell Biology (online September 14).

Researchers discover two proteins controlling the stem cell switch to skin cells

Scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, in collaboration with colleagues at the Centro de Investigaciones Energ-ticas, Medioambientales y Tecnologicas (CIEMAT) in Madrid, have discovered two proteins that control when and how these stem cells switch to being skin cells.

Cellular mechanosensory system may yield new insights for cancer therapy

Every moment, millions of a body's cells flawlessly divvy up their genes and pinch perfectly in half to form two identical progeny for the replenishment of tissues and organs - even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes.

Second-hand tobacco smoke exposure results in NAFLD

A team of scientists at the University of California, Riverside has found that even second-hand tobacco smoke exposure can result in nonalcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury in which fat accumulates in the liver of people who drink little or no alcohol.

Brain's SCN is the master clock that synchronizes other biological clocks in the body

Alexis Webb enters a small room at Washington University in St. Louis with walls, floor and ceiling painted dark green, shuts the door, turns off the lights and bends over a microscope in a black box draped with black cloth. Through the microscope, she can see a single nerve cell on a glass cover slip glowing dimly.

BF STEM tomography allows to visualize fine details of cell structure

Scientists in the National Institute of Biomedical Imaging and Bioengineering (NIBIB) Laboratory of Bioengineering and Physical Science have developed a new technique that allows researchers to visualize fine details of cell structure three-dimensionally in thick sections, thus providing greater insight into how cells are organized and how they function. The work is described in a report published online this week in Nature Methods.
