People who eat nuts more than three times a week have reduced risk of dying from cancer or cardiovascular disease

The PREDIMED nutrition trial based in Spain looked at the effect on the primary prevention of cardiovascular disease of over 7000 older people (aged 55 to 90) randomized to a Mediterranean Diet supplemented with extra virgin olive oil or nuts, compared to a control group following a low fat diet. In Mediterranean regions, nut consumption is relatively high compared to other countries…

Ground-breaking new method of ‘starving’ cancer cells

Chris Proud, Professor of Cellular Regulation in Biological Sciences at the University of Southampton says: "Cancer cells grow and divide much more rapidly than normal cells, meaning they have a much higher demand for and are often starved of, nutrients and oxygen. We have discovered that a cellular component, eEF2K, plays a critical role in allowing cancer cells to survive nutrient starvation, whilst normal, healthy cells do not usually require eEF2K in order to survive. Therefore, by blocking the function of eEF2K, we should be able to kill cancer cells, without harming normal, healthy cells in the process." Almost all cells in the human body contain the same basic components, meaning that to attack one of them in a cancer cell, that component will also be affected in normal cells…

Eating right, exercise may help prostate cancer patients reduce risk of aggressive tumors

Led by Lenore Arab, PhD, JCCC member and professor in the departments of medicine and biological chemistry, the researchers examined associations between adherence to WCRF recommendations and risk of highly aggressive prostate cancer among subjects enrolled in the North Carolina-Louisiana Prostate Cancer Project. …

Molecule considered to be a breast cancer indicator also has a protective function

Researchers from the Centre for Genomic Regulation led by Miguel Beato have, in an article published in the journal Cell Reports, just revealed that one of these molecules (PLK1 kinase), up to now thought to be related to cancer, can also be crucial for the proper functioning of the cell. PLK1 had always been associated with breast cancer due to its role in cell division. …

New screening approach quickly identifies small proteins unique to melanoma cells

The new approach is outlined in an article published online by Nature Medicine in May. A previous phase 2 clinical trial showed substantial regression of metastatic lesions in up to 70 percent of melanoma patients who were treated with self-donated tumor-infiltrating lymphocytes. "The trial, which involved the adaptive transfer of a patient’s own immune cells, showed a complete tumor regression lasting at least five years in nearly 40 percent of the patients," Teer said. …

Chlamydia promotes gene mutations

Researchers at the Max Planck Institute for Infection Biology in Berlin (MPIIB) now show that Chlamydia infections can cause mutations in the host DNA by overriding the normal mechanisms by which their host prevents unregulated growth of genetically damaged cells that pave the way for the development of cancer. Owing to their intracellular lifestyle Chlamydia depend on various host cell functions for their survival. Chlamydia manipulates the host cell mechanism to favour its growth, however the consequences of such alterations on the fate of host cells remains enigmatic…
