| Research Abstract |
The purpose of this research is to identify a pathway of the control mechanism of matrix remodeling in renal cell carcinoma and to examine whether it could be a new therapeutic target and a sensitive marker of anti-angiogenic therapy. This study indicates that the pathway of VHL-atypical PKC-JunB not through the HIF(hypoxia-inducible factor) contributes to the progression of renal cell carcinoma, and we actually confirmed with xenografts from kidney cancer cell lines that the expression of JunB affected tumor growth and angiogenesis. Moreover, we identified matrix metalloproteinase-2(MMP-2), MMP-9 and chemokine(C-C motif) ligand-2(CCL2) as downstream effectors of JunB. The results of their functional analysis suggest that they have the possibility to be new molecular targets for angiogenesis and invasion of renal cell carcinoma.
