Abstract:
Objective To study on the diagnosis methodology of breast cancer using integrated analysis of proteomics and metabonomics approach.Methods The serum samples from the 14 breast cancer patients and 7 healthy people were analyzed by two-dimensional electrophoresis in order, to find differential expressed proteins. On the other hand, an HPLC-based urinary metabonomics profiling was employed to pick out chemical patterns between breast cancer patients and healthy people.Results Glutathione S-transferase M5 was found highly expressed in the breast cancer patients′serum.The concentration pattern of S-Adenosylmethionine, Orotidine, 1-Methyladenosine and N2-Methylguanosine in patients′ urine were peculiarly different from that in the healthy people.Conclusion There are peculiar chemical pattern differentiae between the body fluid of breast cancer patients and the body fluid of healthy people. Synthetic study of cancer proteomics and metabonomics can contribute not only to prognosis of cancer but also to the pathogenesis of cancer.
