View Related Double-strand breaks in DNA can result from external agents such as ultraviolet (UV) radiation or mutagenic chemicals. If left unrepaired, a single DNA double-strand break can lead to cell death or cancer. The Mayo research team showed that 53BP1 -- a human protein essential for repairing DNA double-strand breaks -- is recruited to the sites of DNA damage by direct interaction with histone H4, a protein constituent of the DNA packaging structure called chromatin. Findings are published in Dec. 29, 2006, issue of Cell. View Abstract Findings may help target specific, individualized treatments to patients Certain patients suffering from multiple myeloma, a difficult-to-treat cancer of the plasma cells, may respond positively to a drug that shows potential to extend their survival rates by as much as six months, according to researchers at the Mayo Clinic Cancer Center. For the first time, Mayo researchers have identified tumor-specific alterations in the cellular pathway by which the multiple myeloma drug, bortezomib (Velcade), works, as well as nine new genetic mutations in cancer cells that should increase a patient's chance of responding to the agent. View Related Inside Mayo Clinic Magazine Mayo Clinic researchers have challenged the conventional teaching about a common cancer trait, and in doing so, they discovered how cells are naturally “cancer proofed.“ Their findings were published in the journal Nature. View Abstract Custom-fitting a Drug for a Child with Leukemia Some 20 years ago, Mayo Clinic researcher Richard Weinshilboum, M.D., and colleagues made a groundbreaking discovery: They determined why a dose of a drug that could produce astonishing cures in a lethal childhood cancer sometimes also could produce side effects that killed children. The reason behind this strikingly individual response to a drug was found in the genes. With this profound insight into the role that a patient's genetic make-up plays in how the patient responds to a drug, the new field of pharmacogenomic medicine was born. It continues to grow today—Mayo Clinic research leading the way discovering new treatment applications that range from depression, to breast cancer, to chemical dependency.

View Related Publication: Cancer Research -- Oct. 15, 2006 Combined deletion of chromosomes 1p and 19q is associated with improved prognosis and responsiveness to therapy in patients with anaplastic oligodendroglioma. Jenkins et al. used stem cell culture techniques to recover a t(1;19)(q10;p10) from an oligodendroglioma, suggesting that the translocation likely mediates the combined 1p and 19q deletions. The authors then developed an interphase fluorescence in situ hybridization (FISH) strategy to detect the t(1;19) in paraffin-embedded tumors. Using gliomas from patients enrolled on NCCTG trials, the FISH test demonstrated that the translocation is highly prevalent in oligodendrogliomas and is associated with superior survival.

View Related Mayo Clinic researchers have shown that a subset of T-cells found in non-Hodgkin's lymphoma (NHL) patients inhibits the normal immune response to the cancer. "Treg cells normally control the immune response process, ensuring that the body doesn't fight against itself," says Stephen Ansell, M.D., Ph.D., Mayo Clinic hematology researcher. "This study has shown that there is more to the story for NHL patients, and that the most common Treg cell, which is positive for the cell surface markers CD4 and CD25, actually contributes to disease progression by suppressing a healthy immune response to cancer cells View Abstract Now that this signal has been identified, new strategies can be generated for enhancing the ability of the immune system to kill tumor cells in patients with cancer. "Because NK cells can communicate different messages -- one that serves health by clearing tumors and viruses and one that serves disease by blocking the response to cancer -- understanding which signals result in effective tumor clearance is a high priority for those of us fighting cancer," explains Paul Leibson, M.D., Ph.D., the Mayo Clinic immunologist and pediatrician who led the study. View Abstract Mayo Clinic researchers have discovered clues about new molecular partnerships involving a key protein that naturally guards against cancer because it promotes repair of damaged DNA. Research shows that loss of p53 is directly related to cancer. People born without enough p53 function get spontaneous cancers. In about half of all cancers, the two genes that give the instructions for making p53 (each person gets one gene from each parent) are missing or shut off. This suggests that loss of p53 function is a common event in the origin of many different kinds of cancer. Therefore, an appealing research strategy is to devise ways to restore or protect p53 function. Discovering all the ways p53 gets turned on is an important first step toward doing that. View Abstract Mayo Clinic researchers have uncovered a new cellular secret that may explain how certain cancers move and spread -- a feature of cancers that makes treatment especially difficult. "These findings have broad implications toward the general understanding of how specific processes in the wave may affect such things as cell growth, cell movement and metastasis," explains Mark McNiven, Ph.D., the lead researcher on the Mayo Clinic team. "Our work provides new insights into a novel mechanism by which cells can internalize growth factor information. Understanding this process is the first step toward one day halting it, preventing it or reversing it therapeutically." View Related Identifying alterations in DNA methylation may also be useful in determining cancer progression Researchers at Mayo Clinic have narrowed the search for effective prostate cancer biomarkers (genetic variations that point to a specific disease or condition), identifying changes in the expression of genes of the whole genome closely correlated to prostate cancer development and progression.
