Protein identified that regulates cellular trafficking, potential for anti-cancer therapy

Posted: 22 Sep 2013 12:51 PM PDT

Scientists have identified a new regulator for the intracellular trafficking of proteins between the endoplasmic reticulum and Golgi apparatus, which is a crucial process for maintaining homeostasis and prevention of human disease. The study provides a new avenue to investigate anti-cancer agents that target the regulatory protein UVRAG and/or intracellular trafficking process.

Calming fear during sleep

Posted: 22 Sep 2013 12:51 PM PDT

A fear memory was reduced in people by exposing them to the memory over and over again while they slept. It's the first time that emotional memory has been manipulated during sleep, report scientists. The finding potentially offers a new way to enhance the typical daytime treatment of phobias through exposure therapy by adding a nighttime component. A common treatment for phobias is gradual exposure to the feared object until the fear is extinguished.
