[Study on proteomics of Jurkat cells treated with the extracts from Prunella vulgaris].

ABSTRACT

OBJECTIVE: To analyse the differential proteins of Jurkat cells after treated with the extracts from Prunella vulgaris using two-dimensional electrophoresis and mass spectrum. METHODS: Jurkat cell growth inhibitive effect of the extracts from Prunella vulgaris was analyzed by MTT assay. The total proteins of the cells were extracted after treated with the extracts in a dose of 20 microg/mL. Then 2D and MALDI-TOF-MS were used to assess the differential proteins. RESULTS: The extracts from Prunella vulgaris could depress the proliferation of Jurkat cells in a dose-dependent manner. After 2-DE and MALDI-TOF-MS,11 proteins were identified successfully, including glyceraldehyde-3-phosphate dehydrogenase, coagulation factor VII, Heterogeneous nuclear ribonucleoprotein L, heat shock 70 kDa protein 8 isoform 2, immunoglobulin heavy chain variable region, heterogeneous nuclear ribonucleoprotein A2/B1, zinc finger protein 43, chaperonin containing TCP1, subunit 6A (zeta 1), isoform CRA_b, etc. CONCLUSION: The extracts from Prunella vulgaris could inhibit the growth of Jurkat cells significantly, and lead the proteomics change of Jurkat cells, which may be related to the anti-tumor effect of the extracts from Prunella vulgaris.
