Vital step in cellular migration described by UCSD medical researchers

...ld lead to therapeutic interventions in autoimmune diseases such as multiple sclerosis and Crohn's disease," said the paper's first author Naoyuki Nishiya, Ph.D., a postgraduate researcher in the lab of senior author Mark Ginsberg, M.D., UCSD professor of medicine. "Since cell migration plays an important rol...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

...y. But the hormones also increase cancer and other diseases that limit lifespan. The researchers developed a strain of dwarf rats that were naturally deficient in both growth hormone and in IGF-1. To mimic the rise in growth hormone and IGF-1 during adolescence in normal rats, some of these deficient rats we...

New studies suggest airborne SARS transmission is possible

...ng to Dr. Yu, "no other known routes of infectious diseases transmission could adequately explain the spread of the disease in the outbreak, and hence we feel that the evidence is quite strong." An editorial accompanying the Toronto study, by Tommy Tong, MBBS, of Princess Margaret Hospital in Hong Kong, emph...

Circles Of DNA Might Help Predict Success Of Stem Cell Transplantation

UCLA scientists transform HIV into cancer-seeking missile

...it may be possible to correct acquired and genetic diseases where the mutations exert their harmful effects on the body." Melanoma is a serious form of skin cancer. According to the American Cancer Society, an estimated 59,580 Americans will be diagnosed with melanoma in 2005, and about 7,770 people will die...

First real-time view of developing neurons reveals surprises, say Stanford researchers

...ons are required to retain that information. Some diseases also seem to be caused by brain connections not forming normally. Dyslexia, for example, may be caused by connections failing to form between certain brain regions, whereas schizophrenia may result from too many connections forming. What's more, any...

Plants defy Mendel's inheritance laws, may prompt textbook changes

...ill be an avenue for gene therapy to treat or cure diseases in both plants and animals." The study is publish...d animals in order to correct mutations that cause diseases and abnormal growth. Though further research is required to learn how this form of inheritance happ...

Scientists identify new model Of NK cell development

...ing more effective treatments for cancer and other diseases says Caligiuri. "NK cells are the 'minutemen' of the defense system ?the first to respond to an attack. The more we know about them, the more we can help them do their work. In cancer, as in other diseases, the sooner you intervene, the better." ...

White blood cell waste disposal system plays critical regulatory role

Agilent Technologies releases automated literature search tool for biology researchers

... focusing on proteomics and metabolomics for these diseases as a complement to Labs collaborators' work in genomics. Using Labs' systems biology informatics prototypes, Labs researchers have built qualitative biological models based on experimental data, scientific knowledge from published papers and curated ...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...ring plan of human cells to more effectively treat diseases while also generating fewer side-effects. "We're basically now able to open the hood of yeast, worm, and fly cells and look at the protein interactions inside," said Trey Ideker, a bioengineering professor at the University of California, San Diego ...
