BIOMARKERS FOR SCREENING, PREDICTING, AND MONITORING BENIGN PROSTATE HYPERPLASIA
First Claim
1. A set of biomarkers for screening, predicting and monitoring benign prostate hyperplasia (BPH) comprising any combination of any two or more genes selected from Unigene ID numbers Hs.100431 (CXCL13), Hs.79389 (NELL2), Hs.556045 (SH3), Hs.79732 (FBLN1), Hs.1104 (BMP5), Hs.89791 (WNT2), Hs.26468 (X11L), Hs.245188 (TIMP3), Hs.95420 (JM27), and Hs.211933 (COL4A2).

Abstract
Gene expression data are analyzed using learning machines such as support vector machines (SVM) and ridge regression classifiers to rank genes according to their ability to distinguish between BPH (benign prostatic hyperplasia) and all other conditions. Results are provided showing the correlation of results obtained using data from two independent studies that took place at different times using different microarrays. Genes are ranked according to area-under-the-curve, false discovery rate and fold change.
