Sepsis treatment: Destroying DNA to save the genome

Sepsis—the body's own immune response gone against it—is a major health problem worldwide. It is basically a "hyper" immune response by the body to infection or injury, and is characterized by hyperinflammation, immune system paralysis, cell death, liver and kidney failure, blood clots, and even hemorrhage. An estimated 30 million people suffer from sepsis every year, of which 20%…

Breast cancer: targeted therapy can lead to treatment resistance

If chromosomes are unevenly distributed or otherwise altered during cell division, this normally damages the daughter cells and impairs their viability. Not in cancer cells, however, in which chromosome instability can actually confer a growth advantage under certain circumstances. Moreover, as scientists from the German Cancer Research Center have now demonstrated in mice, changes in the…

Can autophagy stop cancer before it starts?

Just as plastic tips protect the ends of shoelaces and keep them from fraying when we tie them, molecular tips called telomeres protect the ends of chromosomes and keep them from fusing when cells continually divide and duplicate their DNA. But while losing the plastic tips may lead to messy laces, telomere loss may lead to cancer. Salk Institute scientists studying the relationship of telomeres…

How can two types of immune cells arise from one?

The fates of immune cells can be decided at the initial division of a cell. Researchers at St. Jude Children’s Research Hospital have discovered that the production of daughter cells with different roles in the immune system is driven by the lopsided distribution of the signaling protein c-Myc. Nudging c-Myc in one direction or the other could make vaccines more effective or advance…
