Note. MW stands for molecular weight, kDa for kilo Dalton, pI for isoelectric point, PLGS for ProteinLynx Global Server, T0 for 0 min or without zinc exposure (control), T120 for 120 min, ↑ for upregulation, ↓ for downregulation, MCF-7 for breast cancer cells, and MCF10A for breast normal epithelial cells. The PLGS score, protein accession, theoretical MW/pI, matched peptides, and sequence coverage (%) were obtained using ProteinLynx Global Server (PLGS) software (version 3.0, Waters Corporation, USA) and the UniProt (Homo sapiens, human) database. Gene ID was derived from UniProt database. The observed MW and pI were calculated according to the protein standards. The fold changes and p values were acquired from the quantitative analysis of the gel images (each group n = 3) by Delta2D software (version 4.0.8, DECODON Gmbh, Germany). MCF-7 T0/MCF10A T0 is the expression fold change of the proteins in MCF-7 cells compared to MCF10A cells without zinc exposure (T0), MCF-7 T120/MCF10A T120 is the expression fold change of the proteins in MCF-7 cells compared to MCF10A cells following the zinc exposure for 120 min (T120), MCF-7 T120/MCF-7 T0 is the expression fold change of the proteins in MCF-7 cells following zinc exposure for T120 compared to T0, and MCF10A T120/MFC10A T0 is the fold change of the proteins in MCF10A cells following zinc exposure for T120 compared to T0. Molecular functions: I, apoptosis; II, signalling; III, catalytic activity; IV, RNA binding; V, protein synthesis; VI, protein binding; VII, structural; VIII, metal ion binding; IX, molecular chaperone; X, DNA binding; XI, DNA synthesis; XII, metabolism; XIII, lipid binding.
