Mass Spectrometry News and Research

RSS

Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an unknown sample without any prior knowledge of its composition.

Max Planck scientists identify unknown proteins of the herpesvirus

The genome encodes the complete information needed by an organism, including that required for protein production. Viruses, which are up to a thousand times smaller than human cells, have considerably smaller genomes. Using a type of herpesvirus as a model system, the scientists of the Max Planck Institute of Biochemistry in Martinsried near Munich and their collaboration partners at the University of California in San Francisco have shown that the genome of this virus contains much more information than previously assumed.

Research reveals surprisingly complex protein-coding capacity of human cytomegalovirus

New findings reveal the surprisingly complex protein-coding capacity of the human cytomegalovirus, or HCMV, and provide the first steps toward understanding how the virus manipulates human cells during infection. The genome of the HCMV was first sequenced over 20 years ago, but researchers have now investigated the proteome-the complete set of expressed proteins-of this common pathogen as well.

Biomolecular imaging: an interview with Professor Roger Reddel

The reason Children’s Medical Research Institute (CMRI) exists is to find ways to treat or prevent childhood disease. Our research programs are focussed on the areas of cancer cell growth, nerve cell signalling, embryology and gene therapy. These four programs have a shared aim of translating novel findings into new treatments for the benefit of families everywhere.

Researchers show how bacteria control processes in human cells

Bacteria can talk to each other via molecules they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers at Link-ping University in Sweden are showing how bacteria control processes in human cells the same way.

Mass spectrometry can help visualize how drugs work inside living cells to kill infectious microbes

Weill Cornell Medical College researchers report that mass spectrometry, a tool currently used to detect and measure proteins and lipids, can also now allow biologists to "see" for the first time exactly how drugs work inside living cells to kill infectious microbes.

VeriStrat identifies NSCLC patients likely to respond to erlotinib

A study, published in the November 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology, showed the plasma test VeriStrat can predict response but not survival benefit from erlotinib. The study was conducted on a subset of patients enrolled in the NCIC Clinical Trials Group, BR.21 phase III trial of erlotinib versus placebo in previously treated advanced non-small cell lung cancer patients.

Lack of cytokeratin 6A may lead to eye infections

Exposed tissue surfaces, including skin and mucous membranes, are under constant threat of attack by microorganisms in the environment. The layer of cells that line these areas, known as epithelial cells, are the first line of defense against these pathogens, but the underlying molecular mechanisms that allow them to repel microbes are unknown.

Modifying fat intake during pregnancy benefits children regardless of mother's size

If you are overweight and pregnant, your baby isn't destined to a life of obesity after all, according to a new research report published online in The FASEB Journal. In the report, a team of U.S. scientists show that modifying fat intake during pregnancy to a moderate level is enough to benefit the child regardless of the mother's size.
