Abstract: The invention relates to methods for using biomarkers to identify cancer patients that will or are likely to respond to treatment. Specifically, the invention relates to the use of one or more of three association studies of cancer types, gene mutations, or gene expression levels in order to identify cancer patients that will or are likely to respond to treatment with a histone deacetylase (HDAC) inhibitor, alone or in combination with another cancer treatment. The methods may, optionally, further include treating such patient with an HDAC inhibitor, alone or in combination with another cancer treatment.

Abstract: The invention relates to histone deacetylase (HDAC) biomarkers in multiple myeloma. Specifically, the biomarkers are drug specific, histone deacetylase (HDAC) or HDAC6 biomarker peptides, which are acetylated, for multiple myeloma. Alternatively, the biomarkers are drug specific, HDAC6 biomarker peptides, which are acetylated or unacetylated, for multiple myeloma. The invention also relates to a kit comprising a detection agent and instructions for identifying a biomarker peptide of the invention. The invention further relates to a method for monitoring treatment efficiency of an HDAC inhibitor in a subject.

Abstract: The invention described encompasses an isolated DNA sequence encoding all or a portion thereof of a cell surface receptor murine and human erythropoietin (hereinafter EPO-R), along with the isolated polypeptide expressed by the DNA sequence (i.e., isolated EPO-R). The invention also encompasses host cells containing the above-described DNA sequence, preferably, host cells which express the polypeptide encoded by the DNA sequence (EPO-R) at a significantly higher level than that produced by normal red blood cell precursors. The invention further encompasses DNA sequences encoding secreted forms of the human EPO-R and polypeptides corresponding thereto. The EPO-receptor in all of the disclosed forms can be used as models for designing drugs or in pharmaceutical compositions for treating anemias.
