The Effect of Inhibition of CD147 on Matrix Metalloproteinase Expression and Activities in pH5CH8 Hepatocytes.

<p>Downregulation of MMPs with CD147 knockdown in a hepatocyte cell line <i>in-vitro</i>. pH5CH8 cells were transfected with siCtrl (C) or siCD147 (Si) oligonucleotides. Transfected cells and mock controls (M) were cultured in serum free conditions for 48 hrs. Shown in panel A are representative immunoblots of CD147 with the higher (HG CD147) and lower molecular weight (LG CD147) glycoforms, MMP-14 and GAPDH as loading control. Gelatin zymography of MMP-2 and -9 on the conditioned media from the same cells are shown in panel B. Densitometry was performed on the CD147 immunoblots and the results are shown as HG CD147 and LG CD147 forms normalised for GAPDH (n = 3, Panels C and D). Densitometric analysis of gelatin zymography of MMP-9 and MMP-2 are shown (Panels E and F). *p<0.05 using Mann-Whitney U t-test, compared to Mock (n = 3 for all groups).
