Keywords: 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. From the biological point of view, glioma invasion is based on interactions of tumor cells with other neoplastic or non-neoplastic cells and with the cerebral extracellular matrix (ECM). Article  Reviewed-Annotation score: -Experimental evidence at protein level i. MGP was originally isolated from bone tissue and is also expressed in kidney, lung, heart, cartilage and vascular smooth muscle cells [11].

MGP is a calcification inhibitor of arteries and cartilage. Matrix gla protein (MGP) is a protein found in numerous body tissues. 1994, 58 (6): 841-846.

For detection we used the biotinylated goat anti-mouse IgG BA2001 (dilution 1:100), a horseradish peroxidase avidin complex and AEC as substrate (secondary antibody and reagents from Vector Laboratories, Burlingame, CA).

The major cause of ovarian cancer treatment failure in cancer patients is inherent or acquired during treatment drug resistance of cancer. MGP has a high affinity binding to calcium ions, similar to other Gla-containing proteins. 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]. Below are the links to the authors’ original submitted files for images. Int J Cancer. It is … Cancers (Basel) 2014;6:1769–1792. California Privacy Statement, Acta Neuropathol. Two other glioblastoma cell lines, U343MG and H4, showed 11.2-fold and 5.6-fold higher MGP mRNA expression compared to normal brain tissue (Figure 1). BMC Cancer Despite considerable improvements in surgery, radiation therapy and chemotherapy, the prognosis of patients with glioblastoma remains dismal with median survival of about 15 months.

Analysis of MDR genes expression and cross-resistance in eight drug resistant ovarian cancer cell lines. Immunofluorescence showed cytoplasmic staining with accentuation at perinuclear regions in all tested cell lines (Figure 2e–g). 10.1007/s00401-007-0243-4. J Biol Chem. Das bedeutet: Der Körper stellt sie zwar selbst her, aber erst nach einer Aktivierung (gamma-Carboxylierung genannt) durch über die Nahrung aufgenommenes Vitamin K1 können sie ihre Stoffwechselarbeit verrichten. Our data suggest that upregulation of MGP (and possibly other ECM-related components as well) results in unfavorable prognosis via increased migration. The amount of MGP mRNA in glioblastoma tissues (n = 10) was 2.6 – 21.4 fold higher compared to normal cortex tissues (n = 3, set as 100%, ± 3.4%) (Figure 1). Matrix Gla protein (MGP) is a secreted, non-collagenous extracellular matrix protein involved in inhibition of tissue calcification. 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].
