^AData associated with the particular peptide from our proteomics analysis were matched to the peptide database.

^BMCF-7 peptide samples of were labeled with TMT²-126 isobaric tags; MCF-7/ADR peptide samples of were labeled with TMT²-127 isobaric tags. The values of 127/126 represent the relative quantitation ratio of the DEPs in two cells.
