Figure 1From: A Latent Variable Approach for Meta-Analysis of Gene Expression Data from Multiple Microarray ExperimentsExpression of TGFB1. Transforming growth factor beta 1 (TGFB1) gene expression on raw (upper), POE EM (middle) and POE MCMC (lower) scales. This gene is uniformly underexpressed in metastatic samples. Open circles indicate primary tumor samples, and stars indicate metastatic samples.Back to article page
