Abstract:
OBJECTIVETake human oral squamous cell carcinoma Tca8113 as experimental model, and study the anti oral squamous cell carcinoma activity of high mobility group chromosomal protein N2 (HMGN2) molecule.
METHODSTrain a large number of recombinant human HMGN2 expression vector Escherichia coli BL21. HMGN2 was expressed under isopropyl-1-thio-beta-galactopyranoside (IPTG) induction and purified by B-PER GST Fusion Protein Purification Kit. A variety of concentrations HMGN2 were added to cell culture medium, cells were tested by MTT, Hoechst 33342 fluorescence staining, flow cytometry assay and Western-blot.
RESULTSMTT results proved that HMGN2 could significantly inhibit human oral squamous cell carcinoma Tca8113 growth. Hoechst 33342 fluorescence staining, flow cytometry assay test and Western-blot proved HMGN2 could make Tca8113 cells morphological change, make Tca8113 cells block in S period of cell cycle and strongly promote Tca8113 cells to apoptosis.
CONCLUSIONHMGN2 can promote apoptosis of oral squamous cell carcinoma cells.
