  • Title: In vivo growth suppression of rat C6 glioma transplanted in rat brain using antisense oligonucleotide for microtubule-associated protein 1A messenger ribonucleic acid.
    Author: Matsuno A, Katayama H, Murakami M, Nagashima T.
    Journal: Br J Neurosurg; 2004 Aug; 18(4):343-6. PubMed ID: 15702832.
    Abstract:
    Microtubule-associated proteins (MAPs) are essential for various cellular processes such as mitosis. The aim of this study was to verify that the suppression of MAP 1A using antisense oligonucleotide can suppress the in vivo proliferation of C6 glioma cells transplanted in rat brain. After 7 days from transplantation, antisense, sense or scramble phosphorothioate oligodeoxynucleotide for MAP 1A mRNA was gradually delivered into the established tumours through amini-osmotic pump. The mean diameters of the tumours from rats treated with antisense, sense and scramble phosphorothioate oligodeoxynucleotide for MAP 1A mRNA were 2.33, 4.625 and 5.25 mm. There was statistically significant difference in diameters of tumours between rats treated with antisense oligodeoxynucleotide, and those treated with sense or scramble oligodeoxynucleotide. This study strongly suggests the important role of MAP 1A in cell proliferation and its suppressionmay serve as a novel antitumour therapy for gliomas.
