MMP2 and neoplasm: Although the percentage of relative positive cells expressing Ki67 in shPLCγ1+LiCl group was lower than that in con77+LiCl group, the percentage in shPLCγ1+LiCl group was higher than that in shPLCγ1 group (Fig.7D, *p<0.05).Like Ki67 expression in subcutaneous tumor tissue, MMP2 expression level in subcutaneous tumor tissue of con77 group was higher than that in con77+LiCl, shPLCγ1, and shPLCγ1+LiCl groups, while there was no difference between shPLCγ1 and shPLCγ1+LiCl groups or con77+LiCl and shPLCγ1+LiCl groups (Fig.7E, *p<0.05,**p<0.01).
