New, automated tool successfully classifies and relates proteins in unprecedented way

...in Genomics andProteomics," appears in an upcoming special issue of the Journal ofBiomedicine and Biotechnology. "Ourapproach really enables the new field of location proteomics, whichdescribes and relates the location of proteins within cells," saidMurphy, a professor of biological sciences, machine learni...

Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

...someone was born with low weight, they need to pay special attention to prevention tactics, including exercise and weight control to minimize insulin resistance -- the other major factor involved in triggering type 2 diabetes. "In particular, someone who was a low-birth-weight baby can compound the risk of ...

Current human embryonic stem cell lines contaminated UCSD/Salk team finds

... remained contaminated by Neu5Gc evenwhen grown in special culture conditions with commercially availableserum replacements, apparently because these are also derived fromanimal products," said both papers' senior author Ajit Varki, M.D.,UCSD professor of medicine and cellular & molecular medicine, andco...

Researchers Uncover Key Step In Manufacture of Memory Protein

...he early, or inactive, form of BDNF ?proBDNF ?to a special compartment in the neuron (nerve cell.) Once in th...re, the proBDNF binds to CPE, which protrudes from special rafts of fatty, cholesterol-rich molecules known as lipids. If this binding process does not take pl...

Plants respond similarly to signals from friends, enemies

.... The rhizobia then migrate into the root and form special structures called nodules, where they turn atmospheric nitrogen into usable nitrogen for the plant and, in return, take some of the plant's energy to survive. A similar relationship appeared when Weerasinghe studied the signals between plants and nem...

Research advances quest for HIV-1 vaccine

...e to the surface of the virus and they reveal some special characteristics of 4E10 that make it unusually effective at targeting this region. Drs. Burton and Wilson are members of a scientific consortium of laboratories, the International AIDS Vaccine Initiative's Neutralizing Antibody Consortium (IAVI), wh...

Computers to be used to find blueprint for new influenza drug

...dases, enzymes used by the flu virus to snip off a special type of sugar, sialic acid, from the throat cell, allowing the virus to enter the cell and reproduce. The new drug would be chemically similar to the sialic acid, but would act to inhibit the sialidase. This would hinder the virus from entering the ...

Genome-wide mouse study yields link to human leukemia

Thanks to a handful of very special mice, scientists have discovered a new tumor suppressor gene and a unique chemical signature implicated in the development of human leukemia, findings that open up a "treasure box" of opportunity and possibility, study authors say. Researchers in Th...

Jefferson Virologists Coax HIV Out of Hiding

...T and who had undetectable levels ofvirus. Using a special technique, they screened the cells with severaldifferent drugs to determine what stimulated the latent virus the best.“To our surprise, it was IL-7,?he says. “We don’t know why, but it isthe best agent in terms of its ability to stimulate HIV out of ...

New imaging method gives early indication if brain cancer therapy is effective, U-M study shows

A special type of MRI scan that measures the flow of water molecules through the brain can help doctors determine early in the course of brain cancer regimen if a patient's tumor will shrink, a new study shows. Researchers at the University of Michigan Compre...

Discovery of key protein's shape could lead to improved bacterial pneumonia vaccine

...stead be modified by binding thosecarbohydrates to special proteins that stimulate the immune systems ofyoung children. “However such vaccines are so complex that they cancarry carbohydrate targets for only a few specific strains of pneumoniabacteria,?Tuomanen said. “So children are always under-protected,si...

Blood stem cells are used in treating blood cancers like leukemia and other blood diseases, and in patients receiving transplants...

Development of portable infectious disease detector

...iplinary teamhas developed two basic technologies: special electrodes that canmeasure the concentrations of the chemicals that cells consume andexcrete in extremely small volumes and the use of fluids flowingthrough microscopic channels to move and manipulate small numbers ofcells reliably. In the process, t...

UCLA scientists transform HIV into cancer-seeking missile

...ged HIV into a vein in the mouse's tail and used a special optical camera to watch the carrier's movement. "The virus traveled through the animal's bloodstream and homed straight to the cancer cells in the lungs, where the melanoma had migrated," said Chen. When the researchers held the mouse under the cam...

Scientists identify new model Of NK cell development

...oughout the lymph nodes, but rather localized near special sites called parafollicular regions, rich in T cells and NK bright cells. "We thought this was pretty interesting because we know that in order for these NK precursor cells to grow and differentiate, they need one of two cytokines, interleukin-2 or ...

The very unexpected life and death of a leukemic cell

...king the water molecule "heavier" than normal. The special hydrogen serves as a tag that enables researchers to track the utilization of water in the body. The hydrogen incorporates into glucose and the tagged glucose eventually makes its way into the cell's DNA. Researchers gave 19 individuals with CLL a s...
