BACKGROUND/AIMS Elucidation of the molecular mechanisms underlying ovarian cancer (OC) cell invasion and migration may provide important evidence for developing efficient therapy. Recently, Matrix metalloproteinase (MMP) has been shown to be regulated by vascular endothelial growth factor family members, especially placental growth factor (PLGF), as a potential mechanism underlying cancer invas...

Although platelet-rich plasma (PRP) is the plasma fraction that contains higher levels of platelet-sequestered proteins such as growth factors and chemokines, it is also abundant in bioactive lipids whose role in wound healing has not been well characterized. This study provides a preliminary evaluation for the effect of the lipid component of PRP on selected genes related to wound healing. Spr...

ARF couples with TP53 in a canonical signaling pathway to activate cellular senescence for tumor suppressive function under oncogenic insults. However, the mechanisms on aberrant elevation of ARF in cancers are still poorly understood. We previously showed that ARF (p14ARF in human and p19Arf in mouse) elevation correlates with PTEN loss and stabilizes SLUG to reduce cell adhesion in prostate c...

OBJECTIVES To explore the effects of serum from patients with ankylosing spondylitis on the canonical Wnt/β-catenin pathway and to assess whether the serum has an osteogenic effect in MG63 cells. METHODS MG63 cells were cultured with serum from 45 ankylosing spondylitis patients, 30 healthy controls, or 45 rheumatoid arthritis patients. The relative PPARD, fra-1, MMP7, OPG and RANKL mRNA leve...

BACKGROUND/AIM Matrix metalloproteinases (MMPs) are involved in cancer biology. Expression of MMP7 (matrilysin) in colorectal cancer is associated with metastatic disease even though it is expressed in most tumour states. In the present study, our purpose was to analyze MMP7 in bowel and lymph nodes of different tumour stages and to evaluate its expression as a cancer biomarker. PATIENTS AND ...

BACKGROUND The efficacy of oxaliplatin in cancer chemotherapy is limited by the development of drug resistance. MMP7 has been related to the loss of tumor cell response to cytotoxic agents although the exact mechanism is not fully understood. Moreover, MMP7 is an independent prognosis factor for survival in patients with colorectal cancer. The aim of the present study was to analyze the role of...

To delineate the role of matrix metalloproteinase 7 (MMP7) in mammary tumorigenesis, MMP7 was expressed in the normal murine mammary gland cell line, c57MG. MMP7 markedly enhanced the growth rate of the c57MG cells in three-dimensional culture and promoted tumor formation in vivo. Subsequent investigation showed that MMP7 (a) up-regulated ErbB4 receptor levels, (b) solubilized the ErbB4 recepto...

Gastric cancer (GC) develops through deregulation of gene expression and accumulation of epigenetic abnormalities, leading to tumor cell acquisition of malignant features. MicroRNAs (miRNAs) play a critical role in cancer development where they can act as oncogenes or oncosuppressors. To identify miRNAs that are associated with some clinicopathologic features of GC and/or participate in tumor p...

Idiopathic pulmonary fibrosis (IPF) is a complex disease with poorly understood etiology. Previously, we reported upregulation of matrix metalloproteinase 7 (MMP7) in both lung and peripheral blood of IPF patients. Here we report evidence for genetic correlation of plasma levels and promoter polymorphisms (rs11568818 and rs11568819) of MMP7 in a well-characterized IPF cohort. Both the AA genoty...

Previously, we described prostate cancer (PCa) detection (83% sensitivity; 67% specificity) in seminal plasma by CE-MS/MS. Moreover, advanced disease was distinguished from organ-confined tumors with 80% sensitivity and 82% specificity. The discovered biomarkers were naturally occurring fragments of larger seminal proteins, predominantly semenogelin 1 and 2, representing endpoints of the ejacul...
