“Our group, which includes more than 180 myeloma researchers worldwide, has updated the definition of multiple myeloma for diagnostic purposes to include validated biomarkers in addition to the current clinical symptoms used for diagnosis which include, elevated blood calcium levels, kidney failure, anemia and bone lesions,” said lead author S. Vincent Rajkumar, M.D. a hematologist at Mayo Clinic. …

A summary of the research appears in the journal Developmental Cell on Oct. 27. The mystery of the gene, TEM5, began in 2000 with research conducted by Brad St. Croix, Ph.D., working in the laboratory of Bert Vogelstein, M.D., a Howard Hughes Medical Institute investigator and the Clayton Professor of Oncology, and Kenneth Kinzler, Ph.D., professor of oncology at the Johns Hopkins University School of Medicine…
In the AlphaMed Press journal Stem Cells, Shah’s team shows how the toxin-secreting stem cells can be used to eradicate cancer cells remaining in mouse brains after their main tumor has been removed. The stem cells are placed at the site encapsulated in a biodegradable gel. …
One area of interest focuses on histones, the chief component of chromatin, a cluster of large molecules. …
“What we have produced is essentially a system that localizes the epicenter of infection and provides real-time tracking of bacterial activity, giving us rapid feedback on how the bacteria respond to antibiotics,” says principal investigator Sanjay Jain, M.D., an infectious disease specialist at the Johns Hopkins Children’s Center and director of the Center for Inflammation Imaging and Research at Johns Hopkins. Describing their work in the Oct. …
The research, published in the journal Nature Communications, provides evidence for how these particular melanoma cells help tumors resist drugs designed to block blood vessel formation. “For a long time the hope has been that anti-angiogenic therapies would starve tumors of the nutrients they need to thrive, but these drugs haven’t worked as well as we all had hoped,” said Andrew C…
Delivering cancer drugs directly to tumors is difficult. Scientists are working on new approaches to overcome the natural limitations of drugs, including loading them into nanoparticles. “The drug is packaged into a lipid ball significantly smaller than the width of a hair to make it soluble in the blood stream and prevent negative side effects. The drug-containing nanoparticle ball then travels in the bloodstream to the tumor, where it accumulates and the drug is released in the tumor to kill the cancer cells,” said Gavin Robertson, professor of pharmacology, pathology, dermatology, and surgery and director of the Penn State Hershey Melanoma Center. …
The potential contribution of stroma cells to tumour growth has been widely recognised. …
“Exposure to artificial light leads to a significantly higher risk for developing breast cancer,” said Chunla He, a biostatistics graduate student in the UGA College of Public Health. “To decrease the use of artificial light, people should avoid working at night and implement earlier bed times.” Her research, published in the International Archives of Occupational and Environmental Health, examined key studies that included risk factors for developing breast cancer. …
