GO analysis of the NaCl time course. A. Heatmap showing significantly (p-value ≤ 0.05) enriched GO cell component categories after NaCl addition at the indicated times. The p38 SAPK involvement in the category is assessed by comparison with the affected genes found in SB203580 treated wt MEFs. Colours toward red indicate high statistic significance, yellow indicates low statistic significance, and gray indicates no statistic significance. Star marks the tests that are significant after false discovery rate correction (FDR q value ≤ 0.05). Full statistics are shown in the supplementary additional file 5. B. Molecular function GO analysis among the three times of study, as in A. C. Biological process GO analysis among the three times of study, as in A.
