a company's lab "gave me perspective on what careers were out there in the life sciences". Merson went on to do medical research and for the past four years has worked for SHI Consulting, a life sciences consulting firm. Instead of doing bas...
Cigarette smoke causes breaks in DNA and defects to a cell's chromosomes, Pitt study finds

the cell nucleus. The chromosomes are then segregated during cell division, so that each daughter nucleus receives a complete copy of the genetic material. The stage when chromosomes are segregated and become separated is called anaphase. Normally, e...
Molecular motor implicated in tissue remodeling

cells and get their energy from a ubiquitous high-energy molecule called ATP, the team found that MMP-1 gets its energy by breaking the molecular bonds in the collagen filament it is attached to. "In fact," Goldberg says, "with our model, a whole ne...
Rare childhood genetic syndrome identified

a cell. Calcium is one of the body's most important signaling molecules, and normally, cellular calcium levels are tightly regulated. Dr. Mark Keating, senior author of the study and a Howard Hughes Medical Institute investigator at Children's Hospi...

cells to do the most damage. The newest work, says Chapman, helps give scientists an inside-the-cell view of the toxin at work. The toxin employs a four-step process - from cell entry to blocking the release of chemical messengers from nerve endings...
Rice finds 'on-off switch' for buckyball toxicity

cells, regulating processes including cell division and growth. Abnormal kinases have been discovered to be major culprits in many forms of cancer. Because inhibitor drugs strike the abnormal kinases in cancer cells without harming normal tissue, the...
