St. Jude study solves mystery of mammalian ears

...n made the cell extend itself. Therefore, the team developed a line of genetically modified mice that carried only mutant prestin in their outer hair cells. The researchers then tested the animals’ responses to sound. Results of the studies showed no alteration in hearing, which suggested that it did not mat...

Research identifies protein that signals flowering in squash plants

... translocation through the phloem stream have been developed in this system. However, most cucurbits are day-neutral plants, and to investigate the nature of the florigenic signal effectively, it was essential to utilize an obligate SD plant. In day-neutral plants, it is not possible to manipulate flowering by...

Researchers discover inherited mutation for leukemia

...our sons, a grandson and a distant female relative developed this form of leukemia. The chemical change is called DNA methylation. Healthy cells use this process to silence unneeded genes. But abnormal DNA methylation can turn off genes that control cell growth, and that lead to tumor growth. "Our find...

Enzyme delivered in smaller package protects cells from radiation damage

...ing with scientists from Stanford University, have developed a new, smaller gene therapy vector that may be effective in delivering a radioprotective enzyme systemically throughout the body which may spare healthy tissue the long-term consequences of therapeutic irradiation. These results are being presented a...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...signed to develop Alzheimer’s disease. The mice developed normally for six months. Then Shaftel raised the level of IL-1beta in one part of the brain –the hippocampus, an area of the brain that specializes in memory and one of the first parts of the brain to be affected by the disease – and followed the mic...

Releasing fish for the future

...es designed to improve fish survival were recently developed for released line-caught snapper, silver trevally, mulloway, sand whiting, yellowfin bream and dusky flathead. The research, costing more than $1.5 million and funded by NSW DPI and the Recreational Fishing Trust (using money from licence fees), i...

Pregnant mom's exposure to flu vaccine kick-starts fetal immune system

...-specific T cells in cord blood. Recently, a newly developed technique known as MHC tetramer staining has facilitated the detection of antigen-specific T cells. In the June 1 issue of the Journal of Clinical Investigation, a team of researchers led by Rachel Miller from Columbia University used this technique...

Math that powers spam filters used to understand how brain learns to move our muscles

A team of biomedical engineers has developed a computer model that makes use of more or less predictable “guesstimates” of human muscle movements to explain how the brain draws on both what it recently learned and what it’s known for some time to anticipate what it needs to develop new motor...

Simulations unravel outer membrane transport mechanism

How sneaky HIV escapes cells

... Gould speculates that cells may have initially developed exosomes as a quality control mechanism to get rid of clumped proteins, which are generally broken and useless. However, just as retroviruses exploit other cell processes for their own ends, it now appears they rely on exosomes to get out of infecte...

New study reports hotel guests at risk from carbon monoxide poisoning

...identally poisoned. Of those poisoned, 27 died, 66 developed pathological conditions, and 6 had conditions resulting in a jury verdict. Jury verdicts have averaged $4.8 million per incident (range=$1 million-17.5 million). Poisoning occurred at hotels of all classes. According to Lindell K. Weaver, MD, med...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...olates of P. falciparum from around the globe have developed genetic mutations that make them resistant to that...er. Parasites in different geographic regions have developed unique patterns of mutations in the three genes mentioned above. Now, researchers can tell where a d...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...se research lab is in MCG’s biotech incubator, has developed cryoprotectants that can be used safely in higher ...itrification, which takes place in seconds. “We developed a solution where we can warm up tissue in under five minutes and still get no ice formation,” says D...

New study finds genetically engineered crops could play a role in sustainable agriculture

... a public database, Nontarget Effects of Bt Crops, developed by NCEAS ecoinformatics expert, Jim Regetz, that will allow other scientists to conduct congruent analyses.” ...

Brightening prospects of using fluorescent nanotubes in medical applications

...old nanoclusters to burn away cancer cells. He has developed a selective method for attaching the gold clusters to the surface of tumors and then exposing them to wavelengths of light that cause them to grow hot enough to destroy nearby cells. The approach has one drawback: He doesn’t have an easy way to ident...

Breakthrough developments in rheumatoid arthritis reported

... converts into citrulline. Laboratories have developed a test to measure for anti-cyclic citrullinated peptide antibody, or anti-CCP. It is now being used as a diagnostic for rheumatoid arthritis. Scientists are now finding that patients have CCP antibodies months or years prior to the illness, suggestin...

U-M researchers discover gene switched off in cancer can be turned on

...ng on the BRM gene. But new drugs would need to be developed to be more effective in reactivating this gene in cancer cells. Still, researchers are excited about the potential this finding could have in leading to new targets for cancer treatment. “This is a targetable target. We can detect it, but we need ...

Migration alert -- How tumor cells home in on the lymphatic system

... model of the tumor-lymphatic microenvironment and developed computational models to calculate the gradients of the signaling molecule. The study provides the first evidence that tumor cells can both produce and use the same signaling molecule, and it highlights the significance of the biophysical environm...
