Genome-wide gene expression profiles in lungs at Day 1 and Day 3 post MRSA infection.

<p><b>A</b>) Heat map of eight groups, with four replications per group. Each row represents one sample, and each column represents one gene. Fold change ≥ 1.5 up or down, <i>P</i> < 0.01, FDR < 0.05); <b>B</b>) Functional group concept-gene analysis for the comparison between LAC (Day 1) and PBS (Day 1) and between LAC (Day 3) and PBS (Day 3). The figure shows how many genes are involved in selected relevant biological pathways and which functions are significantly up-regulated or down-regulated between the LAC and PBS groups at Day 1 or Day 3 post MRSA infection. The background color for each cell is proportional to the hypergeometric test p value. The more saturated the color is, the smaller the p-value.
