HHS Mgp. Matrix Gla protein (MGP) is, along with osteocalcin, a skeletal member of the family of extracellular mineral‐binding Gla proteins. All experiments were done independently for at least three times. Matrix gla protein (MGP) is a vitamin K-dependent small secretory protein, and functions as a calcification inhibitor. 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]. The involvement of MGP function in glioma cell dynamics remains to be clarified. Świerczewska M, Sterzyńska K, Wojtowicz K, Kaźmierczak D, Iżycki D, Nowicki M, Zabel M, Januchowski R. Int J Mol Sci. To visualize the cell nuclei, the cells were mounted with a DAPI-containing mounting medium (blue). A detailed MGP expression analysis in sensitive (A2780) and resistant to paclitaxel (PAC) (A2780PR) and topotecan (TOP) (A2780TR) ovarian cancer cell lines and their corresponding media was performed.

Unexpectedly, vit K supplementation does not exert beneficial effects on soft connective tissue mineralization in the PXE animal model. 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. Bar = 100 μm (a-d) and 50 μm (e-h). b-d: Knockdown verification on protein levels by immunofluorescence staining revealed decreased fluorescence intensities in U373fast cells for both siRNAs 72 h post-transfection (c, d) compared to control transfected cells (b) (MGP is marked green in the cytoplasm). Wells ("lower chambers") were filled with 30 μl of DMEM alone. Schematic drawing of interaction between cell and ECM mediated by fibronectin and MGP. Edited by: David N. Louis HO, Otmar D. Wistler, Webster K. 2007, Lyon: WHO, 33-49. Conclusion: Matrix Gla protein is … Blood. Compared to control siRNA transfected cells (set at 100%), relative migration at 24 h (48 h after knockdown) following MGP knockdown using two different siRNAs was 47.7% ± 10.3% and 44.5% ± 11.5% in U373fast cells (p = 9.21 × 10-9 and p = 8.33 × 10-10), 36.4% ± 12.1% and 37.27% ± 11.2% in H4 cells (p = 5.14 × 10-10 and p = 1.38 × 10-9), and 35.8% ± 15.5% and 31% ± 9.3% in U343MG cells (p = 1.48 × 10-9 and p = 3.50 × 10-11) (Figure 5).

Correspondence to Co-localization suggests binding occurs during tissue development. 1992, 52 (4): 534-537. Joshi P, Kang SY, Yu KN, Kothapalli C, Lee MY. Vitronectin is a multifunctional plasma and ECM protein, which serves roles in cell adhesion, complement activation, coagulation and fibrinolysis [36–39]. WHO Classification of Tumours of the Central Nervous System. J Biol Chem. We used 16 different glioblastoma samples (n = 10 for mRNA and n = 10 for immunohistochemical analysis, four samples were used for both analysis), including samples from 9 females and 7 males. PubMed Central 10.1016/S0304-3835(01)00416-5. Total RNA was isolated from subconfluent cultured cells using the RNeasy Plus Mini kit (Qiagen, Hilden, Germany), and from glioblastoma tissue using TRIzol (Invitrogen, Karlsruhe, Germany). MGP knockdown was verified using qRT-PCR, showing residual MGP mRNA levels of 1.1% – 12.9% at 24 h, 0.4% – 11.7% at 48 h, and 0.8% – 11.6% at 72 h after knockdown compared to 100% MGP mRNA expression of control transfected cells (n = 8) (Figure 3a). In addition, in silico analyses using the REMBRANDT database (http://rembrandt.nci.nih.gov, accessed 10th march 2009) revealed more than two-fold upregulation of MGP in glioblastomas as compared to non-neoplastic brain tissue, and a correlation (p = 0.0011) between MGP overexpression and worse survival in glioblastomas, suggesting that MGP overexpression is prognostically relevant. PubMed 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. Furthermore, once taken into cell culture glioblastoma cells usually produce increased amounts of ECM components, a process which has been designated mesenchymal drift [5, 6]. doi: 10.1016/j.currproblcancer.2006.12.002. Kollagen) Proteine, die intrazelluläre Strukturelemente formen, z.B. 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).

Fachgebiete: Biochemie. We also investigated the glioma cell lines 86HG39, U343MG and non selected U373MG and could verify MGP protein expression in the supernatants using ELISA. 2008, 13 (1): 69-80. Here, we demonstrated aberrantly high expression of intracellular MGP in GC as compared to adjacent normal tissues by immunohistochemistry. Matrix Gla protein (MGP) is a secreted, non-collagenous extracellular matrix protein involved in inhibition of tissue calcification. Finally, we detected expression of MGP protein in ovarian cancer lesions from different histological type of cancer. MGP is traditionally considered to be involved in the inhibition of calcification of arteries and cartilage [19], and germline mutations in MGP cause Keutel syndrome, leading to ectopic abnormal calcification and midfacial hypoplasia [20]. 2004, 165 (5): 625-630.

By using this website, you agree to our Glioma cells in vitro and in situ express various ECM components that modulate their microenvironment and promote migration, including collagens, laminins, brevican, tenascin-C and SPARC. The role of this protein in drug resistance has not been described so far. We used cell culture supernatant from cell lines U373fast and U373slow, as well as from the cell lines 86HG39, U373MG and U343MG cultured in DMEM without FCS for 24 h (1 × 106 cells). Mineralization of elastic fibers in pseudoxanthoma elasticum (PXE) has been associated with low levels of carboxylated matrix gla protein (MGP), most likely as a consequence of reduced vitamin K (vit K) availability. MGP mRNA level (real time PCR analysis) and protein expression in cell lysates and cell culture medium (Western blot analysis) and protein expression in cancer cells (immunofluorescence analysis) and cancer patient lesions (immunohistochemistry) were determined in this study. To assess the prognostic value of matrix Gla protein (MGP) expression in cases of breast cancer, 9 samples from patients diagnosed with breast cancer who were followed up for more than 10 years were microdissected and then analyzed using Affymetrix U133 Plus 2.0 Arrays.

The major cause of ovarian cancer treatment failure in cancer patients is inherent or acquired during treatment drug resistance of cancer. The tumors were histologically diagnosed as glioblastoma according to WHO criteria [1]. MGP is a 79-amino acid ECM protein containing post-translationally modified γ-carboxyglutamic acid residues resulting from vitamin K dependent carboxylation [17, 18]. Vascular Calcification-New Insights Into Its Mechanism. Measurement was done at 570 nm using an ELISA reader upon 0 h, 24 h, 48 h and 72 h (corresponding to 24 h, 48 h, 72 h and 96 h after transfection). Taking into account previous data on negative prognostic effects of MGP overexpression in glioblastomas, our data suggest that upregulation of MGP in concert with other ECM-related components may result in unfavorable prognosis via increased invasion. 10.1161/01.ATV.0000173313.46222.43. Cancer Lett. Total RNA (0.5 μg) was transcribed in cDNA with the High Capacity cDNA reverse Transcription Kit (Applied Biosystems, Foster City, CA) in a reaction volume of 20 μl.

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). Wound closing was compared between MGP knockdown cells and control transfected cells and evaluated using the analysis FIVE software (Soft Imaging System, Münster, Germany). MGP protein concentrations in cell culture supernatant were quantified using a competitive MGP ELISA kit following manufacturer's instructions (Biomedica, Vienna, Austria). Matrix gla protein (MGP) is one of the mesenchymal genes overexpressed in glioblastoma samples as well as in recurrent gliomas undergoing malignant progression . The presence of MGP in those instances does not correlate well with the calcification inhibitory role. 2001, 165 (1): 63-69. Despite considerable improvements in surgery, radiation therapy and chemotherapy, the prognosis of patients with glioblastoma remains dismal with median survival of about 15 months. 10.1016/j.ccr.2007.12.005. For example, brevican exposed its promigratory attributes after cleavage by members of the ADAMTS protease family [44] and glioma migration on laminin is stimulated by binding of glycosaminoglycans [45]. U373fast, H4 and U343MG cells were seeded at a density of 8 × 104 per well in a 24-well plate.
