Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...nd Molecular Biology, has determined that multiple distress signals in plants converge on a single pathway, which then channels the information to the nucleus. The study was part of a collaborative effort led by Joanne Chory, professor and director of the Plant Biology Laboratory at the Salk Institute for Bio...

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

...ponded to viral replication by displaying signs of distress and cell death and by expressing interferon-beta, a cellular antiviral, in an effort to control the infection.

Why don't all moles progress to melanoma?

...ill the cell. To prevent this, the ER sends out distress signals to activate what scientists call the unfolded protein response (UPR). This slows the protein production process and gets rid of excess incoming amino acids, giving the ER a chance to catch up. If that doesn't work, the UPR causes the cell to ...

New brain-chemistry differences found in depressed women

... of messages related to pain, stress and emotional distress between the body and the brain. They have been called the body's "natural painkillers."

This messaging system normally serves as an effective means of quickly replacing cells that are damaged or killed while keeping us healthy. But...

Mayo Clinic collaboration discovers protein amplifies DNA injury signals

...Now that they understand MDC1's role in amplifying distress calls from injured DNA to cue the repair process, the Mayo researchers are investigating another system that appears to play a similar role in the cell.
