Identification and characterization of Runx2 phosphorylation sites involved in matrix metalloproteinase-13 promoter activation.

Study of Antimetastatic Effect of Genistein Through Inhibition of Expression of Matrix Metalloproteinase in A-549 Cell Line

The lung cancer is one of the most dangerous cancers and is also the leading cause of cancer death worldwide, accounting for about 1.3 million deaths annually. However in clinical practice, lung cancer therapies commonly do with chemotherapy, although it is hard because the lung cancer may progress to metastasis stage. The metastasis of lung cancer is highly dependent of expression of matrix me...

The NAD-Dependent Deacetylase Sirtuin-1 Regulates the Expression of Osteogenic Transcriptional Activator Runt-Related Transcription Factor 2 (Runx2) and Production of Matrix Metalloproteinase (MMP)-13 in Chondrocytes in Osteoarthritis

Aging is one of the major pathologic factors associated with osteoarthritis (OA). Recently, numerous reports have demonstrated the impact of sirtuin-1 (Sirt1), which is the NAD-dependent deacetylase, on human aging. It has been demonstrated that Sirt1 induces osteogenic and chondrogenic differentiation of mesenchymal stem cells. However, the role of Sirt1 in the OA chondrocytes still remains un...

The Role of Matrix Metalloproteinase-3 Functional 5A/6A Promoter Polymorphism in Tumor Cell Progression and Metastasis of Breast Cancer

In the human genome, chromosome 11 contains a cluster of matrix metalloproteinase (MMP) genes. Single nucleotide polymorphisms in the promoter region of MMP genes are important for MMP expression. A common adenine deletion polymorphism (5A) at position -1171 of the MMP-3 gene promoter (5´-AAAAAACCAT-3´ change to 5´-AAAAACCAT-3´) facilitates transcriptional factor binding and MMP-3 promoter acti...

Identification and Characterization of MAPK Phosphorylation Sites in Runx2

Metalloproteinases, Mechanical Factors and Vascular Remodeling

Chronic increases in arterial blood flow elicit an adaptive response of the arterial wall, leading to vessel enlargement and reduction in wall shear stress to physiological baseline value. Release of nitric oxide from endothelial cells exposed to excessive shear is a fundamental step in the remodeling process, and potentially triggers a cascade of events, including growth factor induction and m...
