    Delta-Tocotrienol Description
    Source: From palm oil.
    Biological Activity or Inhibitors: 1. Delta-tocotrienol displays significant radioprotective effects, it protects mouse and human hematopoietic progenitors from gamma-irradiation through extracellular signal-regulated kinase/mammalian target of rapamycin signaling.
    2. Delta-tocotrienol is a potential angiogenic inhibitor, it (2.5-5 microM) can significantly suppress human colorectal adenocarcinoma cells (DLD-1-CM) -induced tube formation, migration, and adhesion on human umbilical vein endothelial cells.
    3.Delta-tocotrienol is a nontoxic activator of mir-34a which can inhibit nonsmall cell lung cancer cells (NSCLC) cell proliferation, induce apoptosis and inhibit invasion, and thus offering a potential starting point for the design of novel anticancer agents.
    4.Grape seed polyphenol and delta-tocotrienol may have benefits in reducing non-alcoholic steatohepatitis (NASH, the second phase in liver disease).
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Delta-tocotrienol protects mouse and human hematopoietic progenitors from gamma-irradiation through extracellular signal-regulated kinase/mammalian target of rapamycin signaling.[Pubmed: 20823133 ]
    Delta-Tocotrienol displayed significant radioprotective effects. A single injection of Delta-Tocotrienol protected 100% of CD2F1 mice from total body irradiation-induced death as measured by 30-day post-irradiation survival. Delta-Tocotrienol increased cell survival, and regeneration of hematopoietic microfoci and lineage(-)/Sca-1(+)/ckit(+) stem and progenitor cells in irradiated mouse bone marrow, and protected human CD34(+) cells from radiation-induced damage. Delta-Tocotrienol activated extracellular signal-related kinase 1/2 phosphorylation and significantly inhibited formation of DNA-damage marker γ-H2AX foci. In addition, Delta-Tocotrienol up-regulated mammalian target of rapamycin and phosphorylation of its downstream effector 4EBP-1. These alterations were associated with activation of mRNA translation regulator eIF4E and ribosomal protein S6, which is responsible for cell survival and growth. Inhibition of extracellular signal-related kinase 1/2 expression by short interfering RNA abrogated Delta-Tocotrienol -induced mammalian target of rapamycin phosphorylation and clonogenicity, and increased γ-H2AX foci formation in irradiated CD34(+) cells.Our data indicate that Delta-Tocotrienol protects mouse bone marrow and human CD34(+) cells from radiation-induced damage through extracellular signal-related kinase activation-associated mammalian target of rapamycin survival pathways.

    Tumor anti-angiogenic effect and mechanism of action of delta-tocotrienol.[Pubmed: 18599020 ]
    Anti-angiogenic therapy mediated by drugs and food components is an established strategy for cancer prevention. Our previous cell-culture studies identified a food-derived anti-angiogenic compound, tocotrienol (T3, an unsaturated vitamin E), as a potential angiogenic inhibitor. Among T3 isomers, Delta-Tocotrienol is considered as the most potent compound. The purpose of this study was therefore to evaluate the inhibitory effect of Delta-Tocotrienol on tumor angiogenesis. As growth factors (e.g., vascular endothelial growth factor and fibroblast growth factor) play critical roles in tumor angiogenesis, a conditioned medium rich in these growth factors from human colorectal adenocarcinoma cells (DLD-1-CM) was used as an angiogenic stimulus. Delta-Tocotrienol (2.5-5 microM) significantly suppressed DLD-1-CM-induced tube formation, migration, and adhesion on human umbilical vein endothelial cells. These effects were partly associated with reactive oxygen species generation by Delta-Tocotrienol . Western blot analysis revealed that the anti-angiogenic effect of Delta-Tocotrienol is attributable to regulation of growth factor-dependent phosphatidylinositol-3 kinase (PI3K)/phosphoinositide-dependent protein kinase (PDK)/Akt signaling as well as to induction stress response in endothelial cells. Moreover, we conducted an in vivo mouse Matrigel plug angiogenesis assay, and found that Delta-Tocotrienol (10-20 microg) exhibits dose-dependent inhibition of DLD-1-induced vessel formation. These results suggest that T3 has potential use as a therapeutic dietary supplement for minimizing tumor angiogenesis.

    Delta-tocotrienol suppresses Notch-1 pathway by upregulating miR-34a in nonsmall cell lung cancer cells.[Pubmed: 22438124 ]
    MicroRNAs (miRNAs) are small noncoding RNAs that play critical roles in regulating various cellular functions by transcriptional silencing. miRNAs can function as either oncogenes or tumor suppressors (oncomirs), depending on cancer types. In our study, using miRNA microarray, we observed that downregulation of the Notch-1 pathway, by Delta-Tocotrienol, correlated with upregulation of miR-34a, in nonsmall cell lung cancer cells (NSCLC). Moreover, re-expression of miR-34a by transfection in NSCLC cells resulted in inhibition of cell growth and invasiveness, induction of apoptosis and enhanced p53 activity. Furthermore, cellular mechanism studies revealed that induction of miR-34a decreased the expression of Notch-1 and its downstream targets including Hes-1, Cyclin D1, Survivin and Bcl-2. Our findings suggest that Delta-Tocotrienol is a nontoxic activator of mir-34a which can inhibit NSCLC cell proliferation, induce apoptosis and inhibit invasion, and thus offering a potential starting point for the design of novel anticancer agents.

    Effect of delta-tocotrienol and grape seed polyphenol on lipid profile in c57bl/6j mice with a western-like diet-induced non-alcoholic steatohepatitis[Reference: WebLink]
    Non-alcoholic steatohepatitis (NASH), the second phase in liver disease, occurs when adults consume high calorie, high fat diets. Fat accumulated in the liver causes inflammation and irreversible hardening. Grape seed polyphenol (GSP) and Delta-Tocotrienol (d-T3) may have benefits in reducing NASH. We observed the effects of dietary GSP & d-T3 (separated and combined: GSP - 2%; d-T3 - 0.05%) in C57BL/6J mice fed a high calorie high fat diet for 20 weeks. Hepatic cholesterol, triglycerides, and vitamin E; serum cholesterol, triglycerides, vitamin E, and free fatty acids were assayed. Hepatic total cholesterol was lowest in GSP diet and GSP(2%)+dT3(0.05%) diet groups. Hepatic triglycerides were lowest in the GSP(2%)+dT3(0.05%) diet group. Hepatic vitamin E levels were lowest in the GSP(2%)+dT3(0.05%) diet group. Serum cholesterol was lowest in GSP diet and GSP(2%)+dT3(0.05%) diet groups. Serum vitamin E was lowest in the GSP diet group. Serum triglycerides and FFA's were similar among the groups.
