Diseases and injuries trigger warning signals in our cells. As a result, genes are expressed and proteins produced, modified or degraded to adapt to the external danger and to protect the organism. In order to be able to produce a particular protein, the corresponding DNA segment, the gene, needs to be expressed and translated. The DNA is localized in the cell nucleus, and exists as a long string that is coiled and bound by proteins. ARTD1 is one such protein, and therefore has the potential...

Berkeley Lab scientists demonstrate the promise of synchrotron infrared spectroscopy of living cells for medical applications Knowing how a living cell works means knowing how the chemistry inside the cell changes as the functions of the cell change. Protein phosphorylation, for example, controls everything from cell proliferation to differentiation to metabolism to signaling, and even programmed cell death (apoptosis), in cells from bacteria to humans. It´s a chemical process that...

St. Jude Children's Research Hospital discovery that a protein vital for cell survival and immune balance has another form with a different function could yield additional cancer treatment strategy Research led by St. Jude Children's Research Hospital investigators suggests that safeguarding cell survival and maintaining a balanced immune system is just the start of the myeloid cell leukemia sequence 1 (MCL1) protein's work. Nearly 20 years after MCL1 was discovered, scientists have...

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...
