Instant immunity through chemically programmable vaccination and covalent self-assembly

The experiments, thus far performed only in mice, appear to overcome a major drawback of vaccinations - the lag time of days, or even weeks, that it normally takes for immunity to build against a pathogen.

Prenatal molecular diagnosis for tuberous sclerosis complex

Geneticists from Boston University School of Medicine (BUSM) have reported the world's first series of cases of prenatal diagnosis for women at risk of having a child with tuberous sclerosis complex (TSC).

Discovery of gene involved in pancreatic cancer

Researchers from the University of Michigan Comprehensive Cancer Center have identified a gene that is overexpressed in 90 percent of pancreatic cancers, the most deadly type of cancer.

Proepithelin encourages cell growth and migration in prostate cancer

Researchers from Thomas Jefferson University have identified a protein that appears to play a significant role in the growth and migration of prostate cancer cells, especially androgen-independent prostate cancer cells.

Study examines maternal and newborn health risks and colorectal cancer

In one of the first studies to examine maternal and newborn health risks and colorectal cancer, UC Davis researchers have found that women diagnosed with the disease during or shortly after their pregnancies have the same survival as women who have the disease and are not pregnant.

Immune system found to be more versatile than previously thought

By studying how mice fight off infection by intestinal worms - a condition that affects more than 1 billion people worldwide - scientists have discovered that the immune system is more versatile than has long been thought.

Scientists measure impact of high-fat diet on the spread of cancer

Researchers at Purdue University have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasizing tumor cells in laboratory animals.

Medivation announces new positive efficacy data from trial of MDV3100 in Castration-resistant prostate cancer

Medivation, Inc. has announced the presentation of new efficacy and safety data from an ongoing Phase 1-2 clinical trial of the Company's novel androgen receptor antagonist MDV3100 in castration-resistant prostate cancer (CRPC) patients.

Liver tumors associated with metabolic syndrome differ from other tumors

Liver cancer in patients whose only risk factor is metabolic syndrome has distinct forms and structures compared to other liver tumors.

Anti-cancer gene discovered

Starting with the tiny fruit fly, and then moving into mouse and human patients, researchers at VIB connected to the Center for Human Genetics (K.U. Leuven) showed that the same gene suppresses cancer in all three.

New cancer treatment stops aggressive sarcomas

After all standard treatments had failed, a new cancer treatment has stopped the growth of aggressive sarcomas in two recent patients. These results are similar to the new protocol's previous success against several cancers, including melanoma, pancreatic, colon, mesothelioma and other sarcomas.

Take 2: What protein and where it is located are important for drug design

Drugs that target a single signaling pathway that drives tumor development and/or progression have been developed successfully to treat a few forms of cancer.

New technique to determine tumor methylation status

Current research suggests that a new technique to determine tumor methylation status can be used in archived tissue samples.

Metastasis-promoting protein identified; could provide a prognostic test or target for breast cancer

Tumors that are about to progress and metastasize go through a process also seen in normal embryonic development, known as the epithelial to mesenchymal transition (EMT).

Reminders may increase colon cancer screening

Mailed reminders to patients appear to promote colon cancer screening, according to a report in the February 23 issue of Archives of Internal Medicine.

Researchers examine role of high cholesterol in prostate cancer

Current research suggests that lowering cholesterol may block the growth of prostate tumors.

Enhanced skin cancer risk linked to defects in cellular aging controls

Cell lifespan is limited by telomeres, DNA sequences that cap chromosomes and control the number of times a cell may be copied.

Gold nanoparticles improve gene regulation

Investigators at Northwestern University have found that packing small interfering RNA (siRNA) molecules onto the surface of a gold nanoparticle can protect siRNAs from degradation and increase their ability to regulate genes involved in cancer. As a result of this discovery, cancer researchers have at their disposal a relatively straightforward method of delivering these potent gene-regulating agents into targeted cells.

Targeted nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light. When heated with lasers, the actively targeted hollow gold nanospheres did eight times more damage to melanoma tumors in mice than did the same nanospheres that gathered less directly in the tumors.

Radiolabeled nanoparticles boost PET-CT combination imaging

In an attempt to decrease the amount of cancer-targeting nanoparticle needed to image tumors, a team of investigators at the Massachusetts General Hospital and Harvard Medical School has developed a simple method for creating iron oxide nanoparticles labeled with 18F, a radioisotope that is easily detected using positron emission tomography (PET). The result is a nanoparticle that can be imaged using PET, computerized tomography (CT), and fluorescence imaging.
