Ostrow School of Dentistry of USC study in Cell Stem Cell outlines the mechanism behind stem cells' beneficial effects on immune disorders A new study, appearing in Cell Stem Cell and led by researchers at the University of Southern California, outlines the specifics of how autoimmune disorders can be controlled by infusions of mesenchymal stem cells. Mesenchymal stem cells (MSC) are highly versatile stem cells that originate from the mesoderm, or middle layer of tissue, in a developing...

Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis. Researchers at the University of Helsinki discovered that spontaneous induction of KSHV lytic replication in tumors drastically attenuated the p53-dependent apoptotic response not only to a targeted therapy (Nutlin-3) but also to genotoxic...

Team discovers mechanism for destroying particular cancer cells An international team of scientists has announced a new advance in the ability to target and destroy certain cancer cells. A group led by the University of Leicester has shown that particular cancer cells are especially sensitive to a protein called p21. This protein usually forces normal and cancer cells to stop dividing but it was recently shown that in some cases it can also kill cancer cells. However, scientists have...

A new finding in basic science should trigger a "change in thinking" about how cancer drugs might be developed and tested for maximum effectiveness, says Louis M. Weiner, M.D., director of the Georgetown Lombardi Comprehensive Cancer Center, in a "Clinical Implications of Basic Research" article titled Tumor-Cell Death, Autophagy, and Immunity published in the March 22 issue of the New England Journal of Medicine (NEJM). An internationally known expert in immunotherapy research, Weiner was...

Salk scientists' discovery explains how a class of chemotherapy drugs works The well-being of living cells requires specialized squads of proteins that maintain order. Degraders chew up worn-out proteins, recyclers wrap up damaged organelles, and-most importantly-DNA repair crews restitch anything that resembles a broken chromosome. If repair is impossible, the crew foreman calls in executioners to annihilate a cell. As unsavory as this last bunch sounds, failure to summon them is one...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
