Screening cuts cervical cancer rates by half

In the wake of Jade Goody's tragic story, the latest Cancer Research UK statistics reveal that there is hope on the horizon for cervical cancer.

Patient knowledge of health information influences cancer treatment

A new analysis finds that when colorectal cancer patients seek out health information from the internet and news media, they are more likely to be aware of and receive the latest treatments for their disease.

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).

Men who are infertile appear to have greater risk for testicular cancer

Men who are infertile appear to have an increased risk of developing testicular cancer, according to a report in the February 23 issue of Archives of Internal Medicine , one of the JAMA/Archives journals.

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.

Calcium linked to lower risk of cancer in women

Women with higher intake of calcium appear to have a lower risk of cancer overall, and both men and women with high calcium intakes have lower risks of colorectal cancer and other cancers of the digestive system, according to a report in the February 23 issue of Archives of Internal Medicine.

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.

Nanoparticles detect dying cancer cells

Two years ago, researchers at the University of South Australia discovered a new molecular marker specific for chemotherapy-induced cancer cell death. Now, those same investigators have used this marker to develop an imaging agent that can pinpoint tumor cell death using magnetic resonance imaging.

Microfluidic device mimics tumor microenvironment, helps drug discovery

One of the challenges that cancer researchers face in designing new antitumor agents is that of predicting how drug molecules will behave in the complex microenvironment that surrounds a tumor. In particular, tumors create all sorts of chemical and physical barriers that limit how much drug is able to enter a tumor, let alone reach cells deep within a tumor.

New imaging techniques let scientists see biomolecules more clearly

Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed increasingly sophisticated imaging devices.

Suppressing cancer with a master control gene

Starting with the tiny fruit fly and then moving into mice and humans, researchers at VIB and K. U. Leuven show that expression of the same gene suppresses cancer in all three organisms. Reciprocally, switching off the gene - called Ato in flies and ATOH1 in mammals - leads to cancer.
