Anti-TNFRSF9 Monoclonal antibody, clone 5C5 [FITC]

Palm oil is rich in various health-beneficial phytonutrients. The vitamin E and the carotenoids make up a large portion of these phytonutrients. The tocotrienols are a relatively newer class of vitamin E isoforms that are actively being researched for its various health promoting properties. In this study, the anti-cancer properties of the delta-tocotrienol (delta-T3) isoform were investigated on a leukemic cell line. A preliminary cytotoxicity assay was carried out to identify delta-T3's potency in inducing cell death. Following this a real time-based gene array experiment was carried out to distinguish the apoptosis genes regulated by delta-T3 in the K562 leukemic cell line. Results show that treatment with delta-T3 significant regulated the expression of several genes that promote apoptosis such as TP53, TP73, HRK, MCL1, CASP7, CASP8, DAPK1, PYCARD, FASLG and TNFRSF9. These findings suggest that palm delta-T3 can exert anti-cancer activities in chronic myeloid leukemic cells

Astrocytic, oligodendroglial and mixed gliomas are the commonest gliomas in adults. They have distinct phenotypes and clinical courses, but as they exist as a continuous histological spectrum, differentiating them can be difficult. Co-deletions of total 1p and 19q are found in the majority of oligodendrogliomas and considered as a diagnostic marker and a prognostic indicator. The 1p status of astrocytomas has not yet been thoroughly examined. Using a chromosome 1 tile path array, we investigated 108 adult astrocytic tumours for copy number alterations. Total 1p deletions were rare (2%), however partial deletions involving 1p36 were frequently identified in anaplastic astrocytomas (22%) and glioblastomas (34%). Multivariate analysis showed that patients with total 1p deletions had significantly longer survival (P=0.005). In nine glioblastomas homozygous deletions at 1p36 were identified. No somatic mutations were found among the five genes located in the homozygously deleted region. However, the CpG island of TNFRSF9 was hypermethylated in 19% of astrocytic tumours and 87% of glioma cell lines. TNFRSF9 expression was upregulated after demethylation of glioma cell lines. Akt3 amplifications were found in four glioblastomas. Our results indicate that 1p deletions are common anaplastic astrocytomas and glioblastomas but are distinct from the 1p abnormalities in oligodendrogliomas.
