Biodegradable nanoprobe images new blood vessel growth

Angiogenesis, the growth of new blood vessels, plays a critical role in several chronic human diseases, including metastatic cancer. In fact, several new anticancer therapies are designed to starve tumors by shutting down angiogenesis, but the lack of a good assay for quantifying angiogenesis in the body has hampered the development of effective antiangiogenesis therapies.

Barcode chip enables cheaper, faster blood testing

A new barcode chip developed by a multi-institutional team of investigators promises to revolutionize diagnostic medical testing. In less than 10 minutes and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases such as cancer and heart disease.

Magnetic nanotags allow sensitive detection of cancer biomarkers

The detection of cancer-associated proteins, or biomarkers, in blood samples is a potentially powerful tool for early diagnosis of cancer and monitoring of cancer treatment.

Just a little squeeze lets proteins assess DNA

To find its target, all a protein needs to do is give quick squeezes as it moves along the DNA strand, suggests new research from The University of Arizona in Tucson.

Both theories about human cellular aging supported by new research

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells.

Discovery of protein that may cause breast cancer to spread

In an important finding published online in Developmental Cell , researchers at Albert Einstein College of Medicine of Yeshiva University, along with collaborators at Massachusetts Institute of Technology, have identified a protein likely responsible for causing breast cancer to spread.

Effects of stem cell source and patient age on stem cell transplantation outcomes

Two studies examining the effects of stem cell source and patient age on stem cell transplantation outcomes were explored at a press conference on Sunday, December 7 during the 50th Annual Meeting of the American Society of Hematology in San Francisco, CA.

Cancer stem-cell model tested by University of Michigan researchers

One of the most promising new ideas about the causes of cancer, known as the cancer stem-cell model, must be reassessed because it is based largely on evidence from a laboratory test that is surprisingly flawed when applied to some cancers, University of Michigan researchers have concluded.
