Abstract

The aim of this study was to investigate the inhibitory effect of glutamate molecular structure and protein on breast cancer cell metastasis and the potential inhibitory mechanism of cell-derived exosomes via MAPK signaling pathway. Breast cancer cell lines with high metastatic potential were selected by in vitro cell culture technique. The effects of specific inhibitors of glutamic acid on the proliferation and metastasis of breast cancer cells were studied. Changes in protein expression profiles were analyzed by proteomics techniques to identify key proteins associated with breast cancer metastasis. Breast cancer cells were treated with inhibitors of the MAPK signaling pathway to evaluate their effect on cell metastasis and compare with exosome treatment. The results showed that the specific inhibitors of glutamate molecular structure could significantly inhibit the proliferation and metastasis of breast cancer cells. Proteomic analysis revealed several down-regulated proteins that are closely related to breast cancer metastasis.

期刊介绍： The International Journal of Biological Macromolecules is a well-established international journal dedicated to research on the chemical and biological aspects of natural macromolecules. Focusing on proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins, biological poly-acids, and nucleic acids, the journal presents the latest findings in molecular structure, properties, biological activities, interactions, modifications, and functional properties. Papers must offer new and novel insights, encompassing related model systems, structural conformational studies, theoretical developments, and analytical techniques. Each paper is required to primarily focus on at least one named biological macromolecule, reflected in the title, abstract, and text.
