(Ivanhoe Newswire) -- Scientists have found a new way to heighten or restore the potency of a widely-used cancer drug. The drug cetuximab is an antibody that interferes with cancer cell growth by blocking a structure known as the epidermal growth factor receptor (EGFR). The drug is often effective for patients with colorectal cancer and squamous cell cancer of the head and neck, but the benefits typically do no last longer than one year. Some patients do not benefit from the drug at all....

Scientists at Dana-Farber Cancer Institute and colleagues overseas have discovered a pair of backup circuits in cancer cells that enable the cells to dodge the effect of a widely used cancer drug. Jamming those circuits with targeted therapies may heighten or restore the drug's potency, according to a study published in the Sept. 7 issue of Science Translational Medicine. The research focused on the drug cetuximab, an antibody that interferes with cancer cell growth by blocking a structure...

Researchers at New York University's Department of Chemistry and NYU Langone Medical Center have developed a compound that blocks signaling from a protein implicated in many types of cancer. The compound is described in the latest issue of the journal Nature Chemical Biology. The researchers examined signaling by receptor tyrosine kinase (RTK). Abnormal RTK signaling is a major underlying cause of various developmental disorders and diseases, including many forms of cancer. RTK signaling...

(Ivanhoe Newswire) -- Researchers have developed a compound that blocks signaling from a protein implicated in many types of cancer. The investigators examined signaling by receptor tyrosine kinase (RTK). Abnormal RTK signaling is an underlying cause of various developmental disorders and diseases, including cancer. The researchers say RTK signaling pathway employs interactions between the proteins known as Sos and Ras and accounts for a wide range of molecular changes that are involved in...

Researchers decode an important mechanism through which insulin in the hypothalamus controls the body's energy balance Fat-rich food makes you fat. Behind this simple equation lie complex signaling pathways, through which the neurotransmitters in the brain control the body's energy balance. Scientists at the Cologne-based Max Planck Institute for Neurological Research and the Cluster of Excellence in Cellular Stress Responses in Ageing-associated Diseases (CECAD) at the University of Cologne...

Brain-derived protein in colorectal cancer Tumor progression is usually ensured by more than one proliferative mechanism. When one of these is shut down by a specifically targeted drug, other mechanisms may emerge. While these events may lead to treatment failure, they may also become an opportunity for researchers to identify novel targets to be further explored. In a paper recently published in the journal Oncology ("BDNF/TrkB content and interaction with gastrin-releasing peptide receptor...

CAMBRIDGE, Mass., April 20, 2011 /PRNewswire/ -- Merrimack Pharmaceuticals, Inc. announced today that five patients have received therapy in a Phase I clinical study combining MM-111 with multiple standard treatment regimens for patients with advanced HER2 positive (HER2+) solid tumors. (Logo: http://photos.prnewswire.com/prnh/20100913/NE63515LOGO ) MM-111 is a bi-specific antibody that targets tumor cells over-expressing ErbB2/HER2. MM-111 is designed to inhibit the signaling between...

An estimated 19 million Americans suffer from depression, and though the symptoms might be recognizable, the brain chemistry that underlies them is incompletely understood. Research suggests that aberrant signaling by a chemical called Brain-Derived Neurotrophic Factor (BDNF) through its receptor TrkB, may contribute to anxiety and depression, and inhibiting this pathway in mice can reduce anxiety and depression-related behaviors. However, translating these findings to clinical studies will...

UT MD Anderson scientists find new biomarkers for erlotinib treatment Two sets of gene expression profiles predict response to a common lung cancer drug for patients that have no guiding indicators for their treatment now, scientists from The University of Texas MD Anderson Cancer Center report at the AACR 102nd Annual Meeting. "The only way we have to predict erlotinib's treatment benefit for patients now is by checking for certain mutations and amplifications of the epidermal growth factor...

Combining targeted therapies might be required for maximum anti-tumor activity when treating HER2-positive breast cancers, according to two new studies by Vanderbilt-Ingram Cancer Center (VICC) investigators. The findings, reported in two papers in the Proceedings of the National Academy of Sciences (PNAS), suggest that upregulation of the HER3 receptor limits the effectiveness of two classes of targeted therapies (HER2- and PI3 kinase-targeted therapies). Therefore targeting HER3 together...
