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…
Many mechanisms contribute to explain this effect called "acquired resistance," but today the group of Manel Esteller, Director of Epigenetics and Cancer Biology at the Bellvitge Biomedical Research Institute (IDIBELL), ICREA researcher and Professor of Genetics at the University of Barcelona, describes in the official Journal of the National Cancer Research Center in the United States, The Journal of The National Cancer Institute, the existence of epigenetic differences that explain the lack of response of the tumor recurs. "We studied colon cancer cells that were initially sensitive to oxaliplatin drug and then became insensitive to this drug and we found that resistant tumors had inactivated a gene (SRBC) in their DNA" says Manel Esteller "the loss of activity supposedly happens in a gene involved in DNA repair. Thus these tumor cells, when receiving the drug, quickly repair the effect thereof and do not die. Studying nearly two hundred patients with colon cancer also found that inactivation of the gene is associated with poorer survival of these people despite treatment. …
"This is the first step toward clinically applying the principles of cancer stem cell biology to control cancer growth and advance the development of durable cures," says principal investigator Dr. John Dick about the findings published online today in Nature Medicine…
"In addition to its role in regulating the cell cycle, cyclin D1 induces Dicer and thereby promotes the maturation of miRNA," says lead researcher Richard Pestell, M.D., Ph.D., Director of the Kimmel Cancer Center at Thomas Jefferson University and Chair of the Department of Cancer Biology. Dicer is a protein that converts inactive hairpin-structured microRNA precursors into their active single stranded form. "The work supports the idea that cancer-causing proteins like cyclin D1 may drive cancer progression in part via miRNA biogenesis." Using antisense RNA, Dr. Pestell’s group was the first to show that cyclin D1 drives mammary tumor growth in vivo. …
"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…
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. …
Results of this work are published in the journal Science on 22 November 2013. The intestinal microbiota is made up of 100,000 billion bacteria. It is a genuine organ, since the bacterial species that comprise it carry out functions crucial to our health, such as the elimination of substances that are foreign to the body (and potentially toxic), or keeping the pathogens that contaminate us at bay. …
EORTC trial 24954 set out to compare two treatment schemes for patients with resectable hypopharyngeal and laryngeal cancers, and the results published in Cancer show that there is a trend towards worse HRQOL scores in patients receiving alternating chemoradiotherapy (Alternating arm) as opposed to those given sequential induction chemotherapy and radiotherapy (Sequential arm). However, very few differences reached the level of statistical significance, and most patients’ HRQOL scores returned to baseline once treatment was completed. Dr. …
Dr. Andrew Bottomley, EORTC Headquarters Associate Director says, "This study utilized a single standardized and validated patient self-assessment tool, the EORTC Core Quality of Life Questionnaire, or the QLQ-C30 for short. We selected thirty EORTC randomized controlled trials which involved eleven different cancer sites for this study. …
According to the Association of University Technology Managers, academic institutions have been collectively generating more than $2 billion in commercialization income over the last several years. Despite this significant commercialization activity, studies have shown that academic institutions face challenges to commercializing their innovations. Identifying and adjusting for these challenges can further boost academic-based research commercialization, thus having significant benefits for universities and consumers. …
