New understanding of cell movement may yield ways to brake cancer's spread

From birth until death, our cells migrate: nerve cells make their vital connections, embryonic cells move to the proper places to form organs, immune cells zero in to destroy pathogenic organisms, and cancer cells metastasize, spreading deadly disease through the body. Scientists studying these migrations didn't know how cells determined where to go. Until now. A Burnham Institute study ha...

Good news for the medical marijuana movement: pot proliferates brain cells and boosts mood

Most drugs of abuse decrease the generation of new neurons in the brain, but the effects of marijuana on this process, called neurogenesis, had not been clear. In a paper appearing online on October 13 in advance of print publication of the November issue of the Journal of Clinical Investigation, Xia Zhang and colleagues from University of Saskatchewan show that a potent and synthetic cann...

Study finds drug may cut down involuntary movements

The medication tetrabenazine cut down involuntary movement in patients with Huntington's disease on average by about 25 percent, with many patients experiencing a greater improvement, according to a study in the February 14 issue of the journal Neurology. Overall, patients who received the medication were six times as likely to be considered by their doctors to have improved considerably,...

Animal brains 'hard-wired' to recognize predator's foot movements, Queen's study suggests

The reason people can approach animals in the wild more easily from a car than by foot may be due to an innate "life detector" tuned to the visual movements of an approaching predator's feet, says Queen's University psychologist Niko Troje. "We believe this visual filter is used to signal the presence of animals that are propelled by the motion of their feet and the force of gravity," sug...

Movement of chromosome in nucleus visualized

The cell is understood to be highly organized, with specialized areas for different functions and molecular motors shuttling components around. Researchers from the University of Illinois' Chicago and Urbana-Champaign campuses now offer the first imaging evidence from live cells of ongoing organization and transport within the cell nucleus. Genes that are active are located mainly in the...

Mayo Clinic researchers discover cancer cells may move via wave stimulation

Mayo Clinic researchers have uncovered a new cellular secret that may explain how certain cancers move and spread -- a feature of cancers that makes treatment especially difficult. If the mechanism that drives cancer movement -- also called metastasis -- can be understood well enough to manipulate it, new and better treatments can be developed for patients with metastatic cancers. Signi...
