In a nationwide study of women with “triple-negative” breast cancer, adding the chemotherapy drug carboplatin or the angiogenesis inhibitor Avastin to standard chemotherapy drugs brought a sharp increase in the number of patients whose tumors shrank away completely, investigators will report at the 2013 San Antonio Breast Cancer Symposium.
Common breast cancer treatments target tumors by blocking or reducing the levels of estrogen in the body. These treatments may be rendered ineffective in patients with high cholesterol, where tumors can rely on the estrogen-mimicking molecule 27HC as an alternative fuel source.
Widely used treatments for type 2 diabetes have different effects on the hearts of men and women, even as the drugs control blood sugar equally well in both sexes, according to researchers at Washington University School of Medicine in St. Louis. The investigators used PET scans to measure heart and whole-body metabolism in patients taking common diabetes drugs.

For patients with stable coronary artery disease (CAD) who are not experiencing a heart attack and an abnormal stress test, treatment of their narrowed arteries by the common procedure of angioplasty may not provide additional benefits compared to drug therapy alone. This finding results from a survey of more than 4,000 patients with myocardial ischemia, or inadequate circulation, led by cardiologists at Stony Brook University School of Medicine. The survey results are published in the online first edition of JAMA Internal Medicine.
• Glioblastoma is the most common and deadly form of brain cancer. • Drugs target specific mutations on the surface of glioblastoma cells. • Glioblastoma cells are able to eliminate the gene mutation to avoid detection when the targeted drug is present. • When the drug is stopped, tumor cells are able to reacquire the gene mutation, which resensitizes them to the drug.
Sometimes the cure can be worse than the disease. Pharmaceutical drugs are known for their potential side effects, and now researchers have updated an extensive toxicology database so that it can be used to track information about therapeutic drugs and their unintentional toxic effects.

Results of a Johns Hopkins study may explain why a chemotherapy drug called cyclophosphamide prevents graft-versus-host (GVHD) disease in people who receive bone marrow transplants. The experiments point to an immune system cell that evades the toxic effects of cyclophosphamide and protects patients from a lethal form of GVHD.

The key is that metformin doesn’t work to lower blood glucose by directly working on the glucose. It works on reducing harmful fat molecules in the liver, which then allows insulin to work better and lower blood sugar levels.
Nanoscale images, presented at the AVS Meeting in Long Beach, Calif., may provide ‘hole’ story on pore-making antibiotic peptides
The risks of developing kidney failure and a calcium deficiency from the popular osteoporosis drug zoledronic acid are extremely rare, according to researchers at Loyola University Health System (LUHS). These findings were presented earlier this month at the American Society for Bone and Mineral Research’s annual meeting.
MK-3475, an anti-PD1 immunotherapy drug with promising results in advanced trials in melanoma is also showing potential in lung cancer based on preliminary phase 1b data presented at the 15th World Conference on Lung Cancer in Sydney, Australia. By blocking the PD-1 protein, the drug alerts the immune system to attack the cancer. It is generally well tolerated and further trials in lung cancer are currently underway.
More than 1 in 10 Americans take antidepressants, but these medications can take weeks—and for some patients, months—before they begin to alleviate symptoms. Now, scientists from the University of Chicago have discovered that selectively blocking a serotonin receptor subtype induces fast-acting antidepressant effects in mice, indicating a potential new class of therapeutics for depression. The work was published Oct. 29 in Molecular Psychiatry.

A University of Colorado Cancer Center study published in the journal PLoS One shows that when colorectal cancer is targeted by the drug bevacizumab (Avastin), tumors may switch dependence from VEGF-A, which is targeted by the drug, to related growth factors in including VEGF-C, VEGF-D and placental growth factor. This change to new growth-factor dependence may allow colorectal cancer to push past bevacizumab’s blockage of VEGF-A to continue to drive tumor growth.
