Abstract The 'universal cell reaction' , a coordinated biphasic response to external stimuli observed in all living cells, was described by Nasonov and his colleagues in the mid-20th century. via CiteULike

“This work has yielded novel information that gives us a better understanding of how certain cardiac diseases can originate”

Researchers at the University of Connecticut Health Center say they have identified a gene they believe plays a significant role in the development of heart disease. via The Herald

“In practical terms, this means that a new world of discovery is opening to scientists interested in studying the genomes of large groups of people on a comparative basis which is a prime basis for our insights about gene mutations that cause disease”

Scientists at Cold Spring Harbor Laboratory have developed a new means of extracting and interpreting data from the human genome that is more powerful and more economical than methods currently employed. via MediLexicon

“They found that stress-inducing agents, such as oxidative stress, recruit a protein called SENP1 that usually cuts cuts a regulator called SUMO1 away from the enzyme SIRT1 so its activity level drops....”

In order for you to live long and prosper, your cells may need to die while they're still healthy. via Wired News

“We want to see if we can block that process and make cells die.”

One way environmental stress causes cancer is by reducing the activity level of an enzyme that causes cell death, researchers say. via EurekAlert!

“To us, it doesn't matter where the cell comes from - whether it's a bladder cell or a blood cell or an adult stem cell - we use whatever cell gets the job done.”

Things in Dr. Anthony Atala's lab at Wake Forest University are not always what they seem. via Time

“This synergy, we believe, will permit a new area of discovery by bringing together viewpoints of basic cell biology that are now focusing on the understanding of the pathogenesis of type 1 diabetes.”

“This copper-free click reaction of azides and DIFO combines the biocompatibility of the Staudinger ligation [a highly successful labeling reaction previously developed in Bertozzi's lab] with the fast reaction kinetics of click chemistry.”

Click chemistry, one of the most exciting and proficient new techniques for labeling biomolecules in vitro, has now been extended to studies in the context of live cells as well. via MediLexicon

“Scientists want to understand how stem cell identity is maintained in plants for so long and how they transition into other cell types.”

G Venugopala Reddy, an assistant professor of plant cell biology at the University of California, Riverside, has received a $1 million grant from the National Science Foundation in the US to investigate how ... via Rediff.com

“We found that efficient ATM activation occurs only when it has physical contact with areas flanking the DNA breaks”

When the genetic material inside a cell's nucleus starts to fall apart, a protein called ATM takes charge and orchestrates the rescue mission. via MediLexicon
