(a) Quantification of cell migration: U373fast, H4 and U343MG cells with blocked MGP expression exhibited reduced migration as compared to control cells transfected with non-silencing siRNA (set at 100%). MGP serves as an inhibitor of cardiovascular calcification as observed in MGP null mice [19, 25] and arterial and valvular calcification after warfarin intake [26, 27]. PubMed Central  The edges of the wound were marked after scratching (time point 0 h), cells migrating over the edges were counted and the number of cells was determined related to the total area of the scratch. J Biol Chem. Correspondence to Mus musculus (Mouse) Status. The mouse monoclonal anti-MGP antibody was applied in a 1:50 dilution at 4°C overnight. Acta Neuropathol. Cancer. Because virtually nothing is known about the mechanisms linking upregulation of MGP and prognosis in gliomas and, more generally, about the function of MGP in tumors, we hypothesized that MGP promotes glioma migration and performed expression and migration analyses.

Bar = 100 μm (a-d) and 50 μm (e-h). Of note, the binding of MGP to vitronectin does not interfere with possible interactions of MGP and BMP2, because the binding regions are different [31]. 1991, 88 (6): 1924-1932. Matrix Gla protein (MGP) is a secreted, non-collagenous extracellular matrix protein involved in inhibition of tissue calcification. 10.1158/1541-7786.MCR-06-0005. Knockdown of MGP using siRNA in three different glioma cell lines led to decreased cell migration as demonstrated using two different migration assays, whereas proliferation remained unchanged. Despite considerable improvements in surgery, radiation therapy and chemotherapy, the prognosis of patients with glioblastoma remains dismal with median survival of about 15 months. Luo G, Ducy P, McKee MD, Pinero GJ, Loyer E, Behringer RR, Karsenty G: Spontaneous calcification of arteries and cartilage in mice lacking matrix GLA protein. The objective of this study was to determine the role of MGP in the vasculature of the lungs and kidneys. To exclude that decreased numbers of migrating cells were the consequence of reduced proliferation, we performed proliferation assays. Multidisciplinary Digital Publishing Institute (MDPI).

MGP is an important factor that might contribute to cancer resistance mechanism by augmenting the interaction of cells with ECM components leading to increased resistance of ovarian cancer cells to paclitaxel and topotecan. Clin Chim Acta. RNAi-mediated knockdown of MGP in three glioma cell lines (U343MG, U373MG, H4) led to marked reduction of migration, as demonstrated by wound healing and transwell assays, while no effect on proliferation was seen.

Paulus W, Huettner C, Tonn JC: Collagens, integrins and the mesenchymal drift in glioblastomas: a comparison of biopsy specimens, spheroid and early monolayer cultures. The function of MGP in these tissues is unclear. These findings suggest that it is stimulation of invasion by MGP and other ECM components, which underlies the unfavorable prognosis of glioblastomas with mesenchymal gene expression profile. More recent whole genome gene expression analyses have identified a subset of glioblastomas that overexpress transcripts of ECM components, corresponding to a mesenchymal gene expression profile and being associated with worse prognosis [7–9]. 1983, 117 (3): 765-771. Arterioscler Thromb Vasc Biol. MTT solution was discarded and 200 μl of isopropanol was added to dissolve the formazan crystals.

All specimens were counterstained using hematoxylin and sections were mounted using imsol-mount. The mechanisms linking MGP knockdown and reduced migration of glioblastoma cells remain to be determined, but based on available evidence it is conceivable that interactions with members of the bone morphogenetic protein (BMP) family and the ECM component vitronectin are involved. e-g: Immunofluorescence of glioblastoma cell lines U373fast (e), H4 (f) and U343MG (g) showed cytoplasmic positivity.

Immunohistochemical analysis of human glioblastoma tissue was done on acetone-fixed (4°C, 8 min) 5- to 8-μm frozen sections. Conclusion: Matrix Gla protein is … Several of the components identified in glioma ECMs are permissive substrates enhancing cell migration, but like the interaction of MGP and vitronectin, effects can be modulated by additional ligands or modifications. The equation fold change = 2-ΔΔct was applied to calculate the relative expression of MGP in siRNA transfected glioma cells versus untransfected glioma cells or tumors versus normal cortex, respectively. Specifically, gene expression profiling studies revealed that matrix gla protein (MGP), whose function has traditionally been linked to inhibition of calcification of arteries and cartilage, is overexpressed in glioblastomas and associated with worse outcome. 2001, 61 (10): 3869-3876. http://www.biomedcentral.com/1471-2407/9/302/prepub.

For immunostaining on paraffin embedded tissue [22, 23], sections were heated in 0.2% (w/v) citric acid at pH 6.0 in a microwave and "kept warm" for 15 min before washing with TBST (10 mM Tris-HCl, 150 mM NaCl, 0.1% Tween; pH 7.6) and incubation with anti-MGP3–15 (1 mg/ml). Curr. The functional role of MGP in neoplasia remains unclear, but in line with our findings in gliomas, increased levels of MGP were found in ovarian, breast, urogenital and skin cancer [12–16], although decreased levels of MGP have been found in colon carcinoma [29], and loss of MGP expression in metastatic renal cell carcinoma and prostatic carcinoma compared with primary tumors has been associated with tumor progression and metastasis [15]. Matrix Gla protein (MGP) is a vitamin K-dependent, extracellular matrix protein. However, little is known about the role of MGP in UC and its upstream signaling regulation.

Jang YC, Tsou R, Gibran NS, Isik FF: Vitronectin deficiency is associated with increased wound fibrinolysis and decreased microvascular angiogenesis in mice. The importance of MGP for vascular health has been demonstrated in MGP-deficient animals, who all died of massive arterial calcification within 6–8 weeks after birth (3). Migrating cells on the bottom side were fixed for 10 min in 3.7% formaldehyde and stained with Hoechst 33258 for 3 min. Only matrix Gla protein in the primary tumor was associated with outcome after TAM treatment or RT in breast cancer patients. Recently, MGP expression was related to cellular differentiation and tumor progression. Mertsch, S., Schurgers, L.J., Weber, K. et al. Differences between two data points were determined by Student's t test where p < 0.05 was considered significant. Two out of these 16 different samples were diagnosed as secondary glioblastoma and 14 were diagnosed as primary glioblastoma. 1992, 52 (4): 534-537. The initial finding of increased MGP expression in glioblastoma tissues compared to normal cortex led us to experiments with glioblastoma cell lines with different migratory phenotype [21]. The mean age (± SEM) of the patients at the time of surgery was 52 (± 0.7), with a range of 35–73 years. For each time point, an exponential dilution series of cells was used with 1 × 105 cells as starting dilution. USA.gov. J Invest Dermatol. 1998, 46 (5): 585-594. An atheromatous plaque, used as positive control, exhibited staining of the media, in part being associated with lipid, which is a normal staining pattern for MGP (Figure 2d). abnormal blood vessels) is responsible for overexpression of this mesenchymal component in gliomas.
