PURPOSE To evaluate human corneal epithelial culture supernatant and tear fluid for the presence of activators and inhibitors of matrix metalloproteinase (MMP)-9, MMP-3, and tissue inhibitor of metalloproteinase (TIMP)-1, respectively, and to evaluate the effect of MMP-3 on the activation of MMP-9 in these specimens. METHODS Unstimulated tear fluid was collected from patients with ocular rosa...

Matrix metalloproteinase (MMP)-9, one of the most widely investigated MMPs, regulates pathological remodeling processes that involve inflammation and fibrosis in cardiovascular disease. MMP-9 directly degrades extracellular matrix (ECM) proteins and activates cytokines and chemokines to regulate tissue remodeling. MMP-9 deletion or inhibition has proven overall beneficial in multiple animal mod...

background: one of the most major obstacles of ovarian tissue vitrification is suboptimal developmental competence of follicles. matrix metalloproteinases 2 (mmp-2) and 9 (mmp-9) and their tissue inhibitors timp-1 and timp-2 are involved in the remodeling of the extracellular matrix in the ovaries. objective: this study aimed to evaluate the expression of mmp-2, mmp-9, timp-1, and timp-2 genes ...

The present study is to measure serum contents of matrix metalloproteinase (MMP)-2 and MMP-9 in Papillary Thyroid Carcinoma (PTC) patients before and after Radiofrequency Ablation (RFA), and to evaluate the correlation of MMP-2 and MMP-9 contents with prognosis. A total of 41 PTC patients who received ultrasound-guided percutaneous RFA between May 2015 and Oct 2016 were included. The number of ...

Matrix metalloproteinases (MMPs) are proteolytic enzymes that play important roles in cancer progression and metastasis. Although serum MMP expression is known to correlate with the primary lesion of breast cancer, there has yet to be a study regarding the correlation between serum MMP expression and metastatic lesions, particularly lymph nodes. The present study evaluated the correlation of se...

Metastasis to lymph nodes and distant organs is the main challenge in the treatment of papillary thyroid cancer. In the current investigation, we aimed to evaluate the synergistic effects of celecoxib (CX) and sodium valproate (VPA) against cell survival, invasiveness properties, and expression of metalloproteinase-2 and -9 (MMP-2 and MMP-9) in  papillary thyroid cancer cell line, BCPAP cells. ...

Background & Objective:  Matrix metalloproteinases-9 (MMP-9) is one of the most important enzymes to breakdown extracellular matrix which plays a major role in tumor invasion and metastasis. This study aimed to determine tumor MMP-9 expression in non-small-cell lung carcinoma (NSCLC) and whethe...
