Now we know that women with negative lymph nodes and low levels of BAG-1 are at risk of developing metastatic disease, and may be good candidates for aggressive cancer treatments. This biomarker is not only a marker for survival in breast cancer patients, but more importantly, it's a marker for women with negative lymph nodes. The team found that BAG-1 was a better predictor than others that have been tested, and were able to determine which women with localised cancer were at greatest risk of cancer spread. Women with low levels of the protein may be good candidates for aggressive treatment, whereas women with high levels may be spared the side effects of such therapies. Return to the topics New Neurone For Memory Neurons are the basic nerve cells of the nervous system.
Sensory neurons transmit nerve impulses toward the spinal cord and the brain.
Motor neurons transmit nerve impulses from the brain to the muscles. And some are involved in remembering. It is generally accepted that new neurons are generated in the adult brain, but until now it was unclear whether these new neurons were essential for memory formation. Tracey Shors at Rutgers University in New Jersey and her team have now shown that they are - for at least one kind of memory. This portion of the brain is involved with many aspects of memory - amongst other things.
