Matrix metallopeptidase 2 (MMP-2) and matrix metallopeptidase 9 (MMP-9) are involved in the breakdown of extracellular matrix in normal physiological processes as well as in disease processes, such as cancer metastasis.
In ATAT for the group of patients with distant metastasis (M1) the superoxide generation rate, MMP-2, 9 activities are about 2 times higher (p < 0.05) than in the subgroup without distant metastases (M0).
Immunohistochemical expression was found for MMP-14 in all primary tumors as well as in all metastases and for MMP-2 expression in most of the samples.
Our results showed, reduction in MMP-2 (p=0.08), MMP-9 (p=0.03), CCL22 (p=0.003) and TGFβ1 (p=0.1) gene expression and Tregs frequency (p=0.01) which play a main role in the development of chronic inflammation, angiogenesis, tumorigenesis and metastasis.
Thymoquinone inhibits metastasis of renal cell carcinoma cell 786-O-SI3 associating with downregulation of MMP-2 and u-PA and suppression of PI3K/Src signaling.
Western blotting results revealed that knocking down ZEB2-AS1 could inhibit cell invasion and metastasis by suppressing the epithelial to mesenchymal transition (EMT) as well as the expressions of matrix metallopeptidase-2 (MMP-2) and MMP-9 in AGS cells.
Therefore, our findings suggest that MIF may promote the invasion and metastasis of OSCC through the activation of MMP-2 and MMP-9 and prompt further investigation into the therapeutic value of MIF for OSCC treatment.
<b>Conclusion:</b><i>WFDC2</i> contributed to ovarian cancer metastasis and EMT as a positive regulator by activating AKT signaling pathway and inducing MMP-2 expression.
The experiments further demonstrated that SPG-56 inhibited the metastasis of breast cancer in MCF-7 and 4T1-bearing mice by altering the expression of MMP2, MMP9, VEGF, Occludin and Claudin.
T-MAN displays a high r<sub>1</sub> relaxivity (∼60.0 mM<sup>-1</sup> s<sup>-1</sup> per Gd<sup>3+</sup> at 1 T) and a large near-infrared (NIR) fluorescence turn-on ratio (∼185-fold) in response to MMP-2, allowing high-spatial-resolution magnetic resonance imaging (MRI) and low-background fluorescence imaging of gastric tumors as well as lymph node (LN) metastasis in living mice.
The effect of tomatidine on the inhibition of matrix metalloproteinase-2 (MMP-2) and MMP-9, gelatinases related to metastasis, was analyzed using gelatin zymography, western blot and immunofluorescence staining.
Melanoma metastasis requires migration and invasion of the malignant tumour cells driven by proteolytic remodelling of the extracellular matrix (ECM) executed by matrix metalloproteinases (MMPs), particularly MMP-2 and MMP-9.
In summary, our study revealed a novel mechanism of the RBMS3/Twsit1/MMP2 axis in the regulation of invasion and metastasis of breast cancer, which may become a potential molecular marker for breast cancer treatment.
Matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) are upregulated in most cancers and play crucial roles in modulating invasion and metastasis.
The identification of the miR-146b/AUF1/ETS2/MMP2 mechanism for promoting bladder cancer invasion provides significant insights into understanding the nature of bladder cancer metastasis.
IHC analysis revealed that a high expression of <i>UCA1</i> was accompanied by a high expression of metastasis-related proteins (MMP-2 and MMP-9), thereby validating the correlation of <i>UCA1</i> expression with metastasis.
