Baseline-adjusted, genotype-specific differential gene expression in response to injury. Several expression patterns are demarcated by the yellow lines: (1) genes that were primarily up-regulated in WT cells after injury, (2) genes that were differentially expressed at baseline between Mmp7^−/− and WT cells, but lost this difference after injury, and (3) genes that were primarily up-regulated in Mmp7^−/− cells in response to injury. Group 3 genes mapped to distinct functional groups, including processes involved in ciliary structure and function, as shown at lower right.
