Neurons, brain cancer cells require the same little-known protein for long-term survival.

Researchers at the UNC School of Medicine have discovered that the protein PARC/CUL9 helps neurons and brain cancer cells override the biochemical mechanisms that lead to cell death in most … Continue Reading Neurons, brain cancer cells require the same little-known protein for long-term survival.

Stanford researchers invent nanotech microchip to diagnose type-1 diabetes.

An inexpensive, portable, microchip-based test for diagnosing type-1 diabetes could improve patient care worldwide and help researchers better understand the disease, according to the device’s inventors at the Stanford University … Continue Reading Stanford researchers invent nanotech microchip to diagnose type-1 diabetes.

Scripps Florida scientists shed new light on nerve cell growth.

Scripps Florida scientists shed new light on nerve cell growth. The study describes how RPM-1 regulates the activity of a single protein known as DLK-1, a protein that regulates neuron development and plays an essential role in axon regeneration. RPM-1 uses PPM-2, an enzyme that removes a phosphate group from a protein thereby altering its function, in combination with ubiquitin ligase activity to directly inhibit DLK-1.

IUD may increase breast cancer risk in certain women.

A new study has found that a specific intrauterine device (IUD) is associated with a greater risk of breast cancer, but not endometrial, ovarian, pancreatic, or lung cancers. The researchers examined data from over 93,000 women in Finland who had used the LNG-IUS to treat their menorrhagia. The women ranged in age from 30 to 49 years. The breast cancer rate for the group using the system for menorrhagia control was approximately 19% higher than the breast cancer rate for the general population. No increase in uterine cancer or ovarian, pancreatic, or lung cancers was seen with IUD use. Other factors, beyond the IUD use, could also be at play, especially factors related to the menorrhagia, so a direct link between IUD use and cancer will need to be proven by additional research.

Discovery of new drug targets for memory impairment in Alzheimer’s Disease.

Discovery of new drug targets for memory impairment in Alzheimer’s Disease. A study from KIST has revealed the novel mechanism of how Alzheimer’s patients might lose their memory. The researchers also propose new therapeutic targets, which include GABA production and release mechanisms in reactive astrocytes for treatment of Alzheimer’s disease. Furthermore, we provide a stepping stone for the development of MAO-B inhibitors with long lasting efficacy.

Study cracks how the brain processes emotions.

Study cracks how the brain processes emotions. Researchers have discovered that fine-grained patterns of neural activity within the orbitofrontal cortex, an area of the brain associated with emotional processing, act as a neural code which captures an individual’s subjective feeling. The findings provide insight into how the brain represents the human’s innermost feelings, what neuroscientists are calling the last frontier of neuroscience, and upend the long-held view that emotion is represented in the brain simply by activation in specialized regions for positive or negative feelings.
