Protein in prostate biopsies signals increased cancer risk

Their findings, reported in the Journal of Clinical Oncology, are the first to quantify, in the setting of a clinical trial, the increased risk of prostate cancer development from the protein ERG. Traditional means of determining risk of prostate cancer — blood tests for the protein prostate-specific antigen (PSA) and biopsies — do not always correlate well with the chances of dying from the disease. Decisions on what to do with the results of these tests can be unclear, leaving doctors and patients frustrated and unsure of how to proceed. …

Scientists create first large catalog of interactions between drugs, proteins

A Spanish National Cancer Research Centre (CNIO) work, led by Alfonso Valencia, Vice-Director of Basic Research, and Michael L. Tress, a researcher on his team, brings together the biggest collection of interactions between pharmacological molecules, including other compounds, and proteins, in the latest edition of the journal Nucleid Acids Research…

New family of proteins linked to major role in cancer

A major new study in the journal Nature sets out the structure of the new family, called glutamate intramembrane proteases – the founding member of which plays a critical role in transforming healthy cells into cancer cells. The research, funded by Cancer Research UK and conducted by scientists at The Institute of Cancer Research, London, defined the structure of a protein called Rce1, and established it as the first known member of a whole new protein family. …

Detailed image shows how genomes are copied

Genomes are built from pairs of long strands of DNA. In previous collaborations with American researchers, Umeå University scientists have shown that DNA polymerase epsilon is one of the three enzymes that build DNA strands in all higher-level organisms from yeast to humans. When the DNA of an organism’s genome is copied, DNA polymerase epsilon is responsible for building about half of the DNA. This process occurs quickly and with very high accuracy to avoid producing mutations that can be detrimental to the cell and to the organism as a whole. …

Cancer increasing as babyboomers age

"The increase in the number of older adults, the association of cancer with aging, the workforce shortage, and the financial stressors across the health care system and family networks all contribute to a crisis in cancer care that is most pronounced in the older population," wrote three members of the Institute of Medication Committee on Improving the Quality of Cancer Care: Addressing the Challenges of an Aging Population in an editorial published In JAMA, The Journal of the American Medical Association. "Often caregiving falls to a family member who is also aging," noted Mary D. Naylor, PhD, FAAN, RN, the Marian S. Ware Professor in Gerontology and the Director of the NewCourtland Center for Transitions and Health and a member of the committee…

New immunotherapy for malignant brain tumors

Animal experiments show that it is relatively easy to treat cancer in the early stages. However, it is far more difficult to successfully treat advanced cancer. Treatment of brain tumors is particularly challenging because regulatory T-cells accumulate in brain tumors and suppress an immune attack. …
