^aThe total number of proteins upregulated/appearing or downregulated/disappearing is recorded in the second column. The first column lists the comparisons CM0 (CH34 metal-shocked to the control), CE0 (metal-starvation to the control), 0AC (AE104 to CH34 under nonchallenging conditions), AM0 (AE104 metal-shocked to the control), and AE0 (metal-starvation to the control). The proteins that disappeared or appeared and were not found in one of the conditions but in the other are listed in the third column. Quantitative results were defined as those with at least a single determination in each of the two conditions, with a two-fold ratio and a distance value >1. Significant results were those that came from at least two determinations in each of the two conditions, with a two-fold ratio and a distance value >1. The last column lists the significantly regulated proteins, which could be correlated with a significantly changed abundance of their sense RNA. The comparison between CH34 and AE104 control cells was not considered for correlation with the transcriptome data (nfc, not further considered).
