Abstract: The present invention relates to methods of identifying gene targets, including methods of using ribonucleoprotein (RNP) immunoprecipitation-microarrays to identify cancer gene targets, such as subsets of RNP-associated mRNAs in breast cancer cell lines. Also presented, are ribonucleotide binding protein-associated biomarkers, panels or sets of ribonucleotide binding protein-associated biomarkers, methods and compositions comprising ribonucleotide-binding protein, associated nucleotides, nucleotide arrays, and kits, plus methods of using HuR-associated biomarkers to facilitate the diagnosis of, monitoring the disease status of, and the progression of treatment of breast cancers to facilitate the diagnosis of and monitoring the disease status or progression of treatment of breast cancers, including drug-resistant breast cancers.
