We used Genomics Portals to study the functional importance of these 85 genes in five different biological processes examined in 4 gene expression datasets [5,6,7,8] which are available in the portal. Here, we present step-by-step instructions for reproducing the results using Miller et.al. [5] dataset which comprises of 251 primary human breast tumors. This dataset was re-processed and curated before being deposited into the back-end databases under the id ``GSE3494Entrez''. The comparison of interest in this case was between the largest (top quartile) and smallest (bottom quartile) tumor with the assumption that large tumors are ``more proliferative'' than small tumors.
