In vivo imaging of siRNA delivery and silencing in tumors

Using magnetic nanoparticles labeled with dye molecules, a team of investigators at the Massachusetts General Hospital has developed a delivery vehicle capable of transporting antitumor small interfering RNA (siRNA) molecules into cells.

Nanosized bioceramic particles could function as efficient gene delivery vehicles with target specificity for the spleen

A detailed comparison of different types of ceramic nanoparticles has found that those made of silica can efficiently transport therapeutic genes to the spleen and trigger a potent immune response capable of attacking tumors.

Nanoparticle-enabled peptide delivery triggers tumor regression

Cells possess a variety of ways of dealing with mutations that can cause them to grow uncontrollably and eventually form a tumor. The tumor suppressor gene p53 plays a critical role in these cancer prevention processes, largely by triggering a form a cell death known as apoptosis.

Interfacing silicon nanowires with mammalian cells

A research team at the University of California, Berkeley, has achieved a significant step toward one of the futuristic goals of nanomedicine and nanobiology-developing technology for "wiring" together individual cells.

Myelin and Huntington's disease

Last month, Dr. George Bartzokis, director of the UCLA Memory Disorders and Alzheimer's Disease Clinic, suggested in the journal Alzheimer's & Dementia that the breakdown of a type of myelin that develops late in life promotes the buildup of toxic amyloid plaques long associated with Alzheimer's disease.

Cholesterol causes changes in gene expression

Experts from the University of Granada carried out research on atherosclerosis from its earliest stages to discover the origin of atheromatous plaques, fatty deposits gradually and irregularly formed in the main arteries, causing the narrowing of the blood vessel.

What makes people susceptible to rheumatoid arthritis?

Peter K. Gregersen, MD, stares at x-rays of hands, searching out the telltale signs of inflamed joints and wrists from his research subjects with rheumatoid arthritis. With these clinical features at his side, he turns to the basic building blocks of life , the human genome , to figure out what makes these people susceptible to the disabling inflammatory condition.

BRCA2 carriers more likely to develop aggressive and lethal prostate cancer

Carriers of a BRCA2 variation specific to Iceland are more likely to develop aggressive and lethal prostate cancer than noncarriers, according to a study published online in the Journal of the National Cancer Institute.

Gamma-secretase acts as a tumor suppressor

Researchers at Burnham Institute for Medical Research (Burnham) have provided the first evidence that gamma-secretase, an enzyme key to the progression of Alzheimer's, acts as a tumor suppressor by altering the pathway of epidermal growth factor receptor (EGFR), a potential treatment target for cancer.

FDA scrutinise companies selling human tissue

Following an inspection blitz by the Food and Drug Administration (FDA) on companies which handle a variety of human material from deceased donors, no serious problems have apparently been unearthed.

New contributor to aggressive cancers

Mutations in the cell adhesion molecule known as integrin alpha 7 (integrin 7) lead to unchecked tumor cell proliferation and a significantly higher incidence in cancer spread, or metastasis, in several cancer cell lines, report researchers at the University of Pittsburgh School of Medicine in a study published in the Journal of the National Cancer Institute.

Researchers reprogram normal tissue cells into embryonic stem cells

Researchers at the Institute for Stem Cell Biology and Medicine at UCLA were able to take normal tissue cells and reprogram them into cells with the same unlimited properties as embryonic stem cells, the cells that are able to give rise to every cell type found in the body.
