Toward explaining why hepatitis B hits men harder than women
Scientists in China are reporting discovery of unusual liver proteins, found only in males, that may help explain the long-standing mystery of why the hepatitis B virus (HBV) sexually discriminates -- hitting men harder than women. view more (2009-11-19)
University of Kent signs licensing deal with Delta Biotechnology Limited
The University of Kent has recently concluded negotiations with Delta Biotechnology - a company with more than twenty years experience in the expression of heterologous proteins - to allow licensing of the technology covered by the University's patent process for increasing the production of disulphide bonded recombinant proteins from the baker's... view more...

Bacteria for plague control in agriculture
Bacillus thuringiensis, a spore bacteria discovered in 1901 by the Japanese scientist Ishiwata and, ten years later, by the German scientist Berliner came across his findings. It is the micro-organism most used as a bio-insecticide throughout the world. It is a bacterium found naturally in ecosystems, frequently on floors and on the surface of... view more... (2003-02-14)
Bug factories for drugs: quality control holds key to quantity
Tiny types of soil bugs already make many of the products we use in washing detergents, foods, and waste treatment, but scientists now hope that similar bacteria will also make the vaccines and drugs of the future, according to new research presented today (Tuesday, 07 September 2004) at the Society for General Microbiology's 155th Meeting at... view more...

Making proteins glow blue
In the beginning, there was protein. 19th-century scientists at least believed that this group of organic compounds were based on some kind of primeval matter. Therefore they named them "proteins" - derived from the Greek word "protos" (the first). It is meanwhile known that the structure of proteins is ultimately determined by... view more... (2003-09-18)
A search for biomarkers for early detection of colorectal cancer
Researchers at the Zhejiang University, Hangzhou have discovered that mimecan and Thioredoxin Domain-Containing Protein 5 (TXNDC5) were differentially expressed in colorectal adenoma. view more (2007-09-25)
Certain diseases, birth defects may be linked to failure of protein recycling system
A group of signaling proteins known as Wnt - which help build the human body's skin, bone, muscle and other tissues - depend on a complex delivery and recycling system to ensure their transport to tissue-building cell sites, according to a study at Cincinnati Children's Hospital Medical Center. view more (2007-12-21)
UIC researchers show how cancer-preventing foods work
Researchers at the University of Illinois at Chicago are unraveling the biochemical mechanism by which functional foods combat cancer. view more (2005-07-11)
Dynamic molecular mechanism to keep brain activity stable
In the brain, many types of synaptic proteins are spatio-temporally regulated to maintain synaptic activity at a constant level. view more (2009-07-13)
ISU researcher identifies key function in protein, cell transcription
When cells decide to make proteins, key building blocks of all organisms, they need to know where to start reading the instructions for assembling them. view more (2009-05-04)
University of Toronto scientists map entire yeast genome
University of Toronto scientists have devised a tool to help understand and predict the state of a cell by successfully mapping all 70,000 nucleosomes in yeast. Nucleosomes wrap DNA before it is transformed into proteins and are critical indicators and regulators of a cell's state. view more (2007-11-27)
'Nanodrop' test tubes created with a flip of a switch
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new device that creates nanodroplet "test tubes" for studying individual proteins under conditions that mimic the crowded confines of a living cell. view more (2008-04-16)
Chemosensitivity of cancer cells depends on their protein dependency
Two different anti-apoptotic proteins support cancer cell survival via an identical mechanism, yet differ in their sensitivity to chemotherapeutic drugs, report Brunelle et al. The study will be published online October 26, 2009 and in the November 2, 2009 print issue of the Journal of Cell Biology (JCB). view more (2009-10-26)
Chips are down as Manchester makes protein scanning breakthrough
Scientists at The University of Manchester have developed a new and fast method for making biological 'chips' - technology that could lead to quick testing for serious diseases, fast detection of MRSA infections and rapid discovery of new drugs. view more (2008-08-25)
Inhibiting Proteins May Prevent Cartilage Breakdown in Arthritis Patients
Current arthritis medications can ease the pain, but stopping the progression of the disease requires more aggressive treatments: use of very limited available drugs or surgical intervention. University of Missouri researchers hope to find new therapeutic targets for arthritis by studying the interaction between two proteins that, if interrupted,... view more... (2009-02-19)
Plague proteome reveals proteins linked to infection
Recreating growth conditions in flea carriers and mammal hosts, Pacific Northwest National Laboratory scientists have uncovered 176 proteins and likely proteins in the plague-bacterium Yersinia pestis whose numbers rise and fall according to the disease's virulence. view more (2006-11-27)
Scientists Present 'Moving' Theory Behind Bacterial Decision-Making
Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases. view more (2008-11-25)
New family of antibacterial agents uncovered
As bacteria resistant to commonly used antibiotics continue to increase in number, scientists keep searching for new sources of drugs. In this week's JBC, one potential new bactericide has been found in the tiny freshwater animal Hydra. view more (2009-01-16)
New technique boosts by four times the size of a protein that researchers can analyze
Imagine you had to break a secret code, but you could see only part of the message. That's the kind of frustration researchers face when trying to identify proteins and characterize how those proteins are modified in cells by biological processes. view more (2006-10-09)
Protein protects brain against compound in lead poisoning, liver disease
Scientists have discovered that a protein known as PEPT2 protects the brains of mice from a naturally occurring but potentially toxic compound present in lead poisoning and in a class of liver diseases that can cause serious neurological complications. view more (2007-12-07)
