Alternate view for pathology of AD

...sphorylation is further supported by the fact that embryonic neurons that survive after treatment with oxidants have increased tau phosphorylation relative to those that die. It is also apparent that NFT-like tau phosphorylation occurs during hibernation, a neuroprotective phenomenon." "Therefore, Smith added ...

Insulin-producing cells from brain cursors

...es is to look beyond immature pancreatic cells and embryonic stem cells to other early cell types. Kim and colleagues took cells derived from brain which usually mature into neural cells, and exposed them to a series of signals that are known to drive pancreatic islet development. They were able to produce clu...

A new look at genes that cause testicular cancer

Among the known risk factors for developing testicular germ cell cancer, genetic predisposition is a key component. To date, ove...

News tips from the journal of Neuroscience

...nk Cloutier, Kelly Sharp, and Oswald Steward Human embryonic stem cells (hESCs) hold tremendous therapeutic promise, provided they can be harnessed to fulfill specific cellular or tissue functions. This week, Keirstead et al. show that after spinal cord injury in the rat, neuronal loss is compounded by the los...

Premature use of stem cell therapy could put patients at risk

... warn experts in this week's BMJ. The use of human embryonic stem cells has been hailed as the next major step in the battle against serious degenerative disorders, such as diabetes and Parkinson's disease. But is this just hype, and how much hope should patients invest in this technology? These are some of th...

Scientists discover how Nipah virus enters cells

...Australia. Both viruses use a protein essential to embryonic development to enter cells and begin their often-fatal attack, report researchers at the University of California, Los Angeles (UCLA) and the Uniformed Services University of the Health Sciences (USUHS) in Bethesda, MD. The UCLA team, headed by Benh...

Gene found in 90 percent of breast cancers may be cancer vaccine target

...STON - A gene that appears to help regulate normal embryonic development is found at high levels in virtually all forms of breast cancer, according to a new study led by Laszlo Radvanyi, Ph.D., associate professor of breast and melanoma medical oncology at The University of Texas M. D. Anderson Cancer Center. ...

Penn researchers discover a molecular pathway that leads to recurrence of breast cancer

...shown that Snail, a molecule normally important in embryonic development, can promote breast cancer recurrence. They also found that high Snail expression predicts more rapid tumor recurrence in women who have been treated for breast cancer. These observations suggest that Snail may represent a target for canc...

Americans think commitment to health research should be stronger

...pent. A majority of Americans (58 percent) favor embryonic stem cell research, while 34 percent strongly favor it. Of the 29 percent of people opposed to stem cell research, 57 percent said their position was based on religious objections. 56 percent of Americans do not believe an abstinence-only approach ...
