  • a Filtered with confidence value > 90.

  • b Filtered with ΔCN = 0.1, Xcorr = 1.80, 2.38, and 3.08 for 1+,2+, and 3+, respectively.

  • c Refers to proteins identified by at least 2 different peptide sequences.

  • d Bold number represents the matching up- and down-regulated proteins, whereas the number in the parentheses indicates all the up- and down-regulated proteins (matching proteins and single algorithm observations).
