Source of molecular triggers in cutaneous T cell lymphoma identified

...d of normal but usually inactive genes. The study reports that CTCL develops from a small subset of lymphocytes that are pre-programmed to respond to self-antigens exposed during normal cell death. As cells undergo the process of apoptosis, cryptic -- or masked -- antigens, are uncovered. Those newly availa...

Antibiotic Resistant Bacterium Uses Sonar-like Strategy to “See?Enemies or Prey

...tance sticks to foreign cells.The second substance reports back and tells the Enterococcus to makethe toxin. If no cells are in the area, the first substance sticks tothe second, preventing it from reporting back to the Enterococcus, andas a result, no toxin is made. According to Gilmore, “These bacteriaare ...

Researchers identify target for cancer drugs

...teins do together. In this latest paper, Sarbassov reports that when mTOR and rictor bind and form a complex, they help activate Akt by adding a phosphate group to a sequence of its amino acids (a process called "phosphorylation"). This process occurs not only in human cells but in other organisms such as t...

Researchers add new tool to tumor-treatment arsenal

...ys Dr. Thomas, have probably contributed to recent reports of the under-dosing of patients and the failure to blunt the disease. When cancer cells are treated with a DNA-damaging agent, a cancer-suppressing gene known as the "guardian of the cell" (a protein called p53) responds by either killing the cell, ...

Alcohol's effects on gene expression in the central nervous system
