More importantly, utilizing the intrinsic enzyme-like activity of the Au cluster probes, the expression level of MT1-MMP on the SH-SY5Y cells could be assessed by the naked eye without cell lysis and protein extraction process.
Taken together, HNF4α exhibits oncogenic activity that affects the aggressiveness and angiogenesis of NB through activating the transcription of MMP-14.
Taken together, these data indicate that miR-337-3p directly binds the MMP-14 promoter to repress its transcription, thus suppressing the progression of NB.
The potential mechanisms for the inhibition of NB migration and invasion by vandetanib may partly be attributed to the ability of vandetanib to suppress the expression of CXCR4 and MMP14 in human NB cells.
Overexpression or knockdown of miR-9 responsively altered both the mRNA and protein levels of MMP-14 and its downstream gene, vascular endothelial growth factor, in cultured neuroblastoma cell lines SH-SY5Y and SK-N-SH.
Of several matrix metalloproteinases (MMPs) and a tissue inhibitor of MMPs (TIMP), only membrane-bound type 1 MMP (MT1-MMP) was specifically detected in N-myc-amplified cells, suggesting a role of MT1-MMP in neuroblastoma cell invasion.
