Differential expression of genes in NaB vs. Control NOT Doxy + NaB vs. Doxy. (A) Condition tree. Genes are displayed as normalized to the median expression across 4 samples within each experiment (>two-fold, paired T-test, P < 0.01, 1008 probes). Red/Orange = Up-regulated relative to median, Yellow = Median expression, Blue = Dn-regulated relative to median. (B) Venn diagram emphasizes comparison of NaB vs. Ctrl or Doxy + NaB vs. Doxy (>two-fold, paired T-test, P < 0.01).
