Acquiring high proliferation rate is crucial for carcinogenic transformation of cells. We reporthere proteome profiling of human breast epithelial cells with low (184A1) and high (MCF10A)proliferation rates.We identified 183 proteins in 184A1 and 318 proteins in MCF10A cells. Thesedatasets provide the most comprehensive proteome annotations of 184A1 and MCF10A cells.Proteins were taken for identification from 2-D gels in a systematic and unbiased way. Functionalclustering of the identified proteins showed similarities in distribution of proteins to the samefunctional domains, indicating similarities in proteomes of 184A1 and MCF10A cells. Amongobserved differences in protein expression, we validated correlation of expression of endogenouscyclin-dependent kinase 4 (CDK4), cyclin D3, cdc25B, and p38g with cell proliferation. Furthermore,down-regulation of CDK4 and cyclin D3 with specific siRNA inhibited cell proliferation,which emphasized the role of CDK4 and cyclin D3 in enhancement of cell proliferation rate ofhuman breast epithelial cells.
