A fresh look at existing therapies: Researchers explore ways to teach approved drugs new tricks

... Manuel Hidalgo, M.D., Ph.D., suspected that pancreatic cancer − a disease in which EGFR-targeted therapies have proved to be of use, but where amplifications or mutations in the EGFR gene are rare − is an example of a cancer driven by pathway addiction. The problem, however, is that no one knows what ...

New Mouse Model to Aid in Cancer-causing Genes Hunt

...mphoma, or T-ALL, and the cancer cells showed rampant genome instability resulting in intricate pattern of mutations, chromosomal rearrangements, gene amplifications and gene deletions similar to those in human solid tumors. Researchers characterized these mouse tumors by performing high-resolution array-C...

Breast Cancer and HER-2/neu: Diagnostic Tools for Targeted Therapy

...plication and cell division. Her-2/neu therefore falls into the class of proto-oncogenes. A key discovery is that some 2530% of breast cancers carry amplifications (multiple copies) of the Her-2/neu gene, which lead to overexpression of Her-2/neu protein. The over-abundance of Her-2/neu receptor accelerates the ...

Genome changes tracked during multiple myeloma initiation, progression and treatment

...iles of outcome-annotated MM clinical specimens. The researchers discovered a high level of molecular heterogeneity typified by many new recurrent amplifications and deletions that point to a large number of yet-to-be-discovered oncogenes and tumor suppressor genes. These amplification and deletion patterns def...
