Western blotting was to measure matrix metalloproteinase (MMP)-2, MMP-9, and the tissue inhibitor of metalloproteinase 2 (TIMP2) protein levels. qRT-PCR indicated that LINC00312 expression was lower but miR-197-3p expression was higher in BC tissues compared with adjacent tissues; LINC00312 was negatively correlated with miR-197-3p.
The results indicate that TIMP-2 and MMP-2:TIMP-2 complex associate with favorable clinical course and could be used as a novel prognostic indicators in bladder cancer.
To detect the level of matrix metalloproteinase-2 (MMP-2) mRNA and the tissue inhibitor of metalloproteinase-2 (TIMP-2) mRNA in bladder transitional cell carcinoma (BTCC), and to estimate the prognosis for bladder tumor based on the quality and quantity of MMP-2 and TIMP-2 mRNA.
