ABSTRACT
Objective To provide a new putative target for immunotherapy on osteosarcoma and explore the effect of matrix metalloproteinase-9 (MMP-9) on the formation of soluble MICA protein in osteosarcoma cells. Methods MMP-9 antisense oligonucleotide was transfected to osteosarcoma cells with lipofectamine 2000. MMP-9 mRNA was assessed by RT-PCR. MMP-9 activity and soluble MICA (sMICA) in the culture supernatant was examined by zymography and quantified by ELISA, respectively. Results MMP-9 mRNA expression and gelatin enzymatic activity were inhibited in MMP-9 antisense oligonucleotide group. Comparing with the control group, lower concentration of sMICA was found in MMP-9 antisense oligonucleotide group (P = 0.011). Conclusion MMP-9 may have an effect on the formation of sMICA protein in osteosarcoma. MMP-9 could be regarded as a putative target for immunotherapy in osteosarcoma.
