Is a cancer drug working? Modified drug gives a ‘green light’ for its own success

Cancer drugs can be modified to specifically target tumour sites to help personalize cancer treatment. And while it is relatively easy to determine if the drugs have been delivered to the correct location, it is more difficult to monitor their therapeutic success. Now, a team led by Bin Liu from the A*STAR Institute of Materials Research and Engineering in Singapore, in collaboration with Ben Zhong Tang at Hong Kong University of Science and Technology, has developed an anticancer drug with an inbuilt mechanism that shows if it is working. Platinum-based drugs are effective against many cancers, killing cells by triggering cellular suicide, or apoptosis…

New drug target can break down cancer’s barrier against treatment

The team at Barts Cancer Institute, part of Queen Mary University of London, have found that a molecule, called focal adhesion kinase (FAK), signals the body to repair itself after chemotherapy or radiotherapy, which kill cancer cells by damaging DNA. When the researchers removed FAK from blood vessels that grew in melanoma or lung cancer models, both chemotherapy and radiation therapies were far more effective in killing the tumors. The researchers also studied samples taken from lymphoma patients. Those with low levels of FAK in their blood vessels were more likely to have complete remission following treatment. …

Understanding melanoma development

Fair-skinned people who tend to burn (rather than tan) from sun exposure have a much higher risk for melanoma than darker-skinned people. On the surface, it appears that the amount of melanin, the natural substance in the skin that determines pigment and acts as the skin’s “natural sunscreen,” would be the only determinant of melanoma risk. However, the truth is more complicated. …

Significant side effects experienced by BRCA mutation carriers following cancer risk-reducing surgical procedure

“These results reinforce the need for care providers to better understand and communicate with patients about the possible long-term effects of bilateral RRSO,” said lead author Susan Domchek, MD, director of Penn’s Basser Research Center for BRCA. …

New route for ovarian cancer spread discovered

“This completely new way of thinking about ovarian cancer metastasis provides new potential avenues to predict and prevent recurrence or metastasis,” said senior author Anil Sood, M.D., professor of Gynecologic Oncology and Reproductive Medicine and Cancer Biology. The researchers found the circulating tumor cells (CTCs) rely on HER3, a less-famous sibling of the HER2 receptor protein prominent in some breast cancers, to find their way to the omentum, a sheet of tissue that covers and supports abdominal organs. HER3’s heavy presence on these cells makes it a biomarker candidate and suggests possible therapeutic options to thwart ovarian cancer progression, the researchers noted…

New myeloma-obesity research shows drugs can team with body’s defenses

And with current obesity trends in the United States and especially in South Texas, that’s ominous. “I’m predicting an increase in multiple myeloma,” said Edward Medina, M.D., Ph.D., “and with the obesity problems we see in the Hispanic population, there could be a serious health disparity on the horizon.” Dr. Medina, a hematopathologist and assistant professor in the Department of Pathology at The University of Texas Health Science Center at San Antonio, is looking at exactly how obesity causes an increased risk for myeloma…

Gut microbes turn carbs into colorectal cancer, study shows

“Because hereditary colorectal cancer is associated with aggressive and rapid tumor development, it is critical to understand how major environmental factors such as microbes and diet interact with genetic factors to potentially affect disease progression,” says senior study author Alberto Martin of the University of Toronto. “Our study provides novel insights into this question by showing that gut bacteria interact with a carbohydrate-rich diet to stimulate a prevalent type of hereditary colon cancer.” Carbohydrates account for about half of the daily caloric intake of adults on a western-style diet, and previous studies have linked carbohydrate-rich diets to colorectal cancer in humans. This type of cancer is also frequently associated with mutations in a tumor suppressor gene called APC as well as the MSH2 gene, which plays a critical role in repairing DNA damage…
