Intervention Of Non-Small Cell Line Cancer Oncogenic Pathways With Delta-Tocotrienol, Xiangming Ji

Wayne State University Dissertations

Non-small cell lung cancer (NSCLC) is most hostile and leading cause of cancer deaths in the United States. Clinical data has demonstrated that 30 % of NSCLC patients have increased Notch activity and 10% of NSCLC have gain-of-function mutation on Notch-1 gene. Our data demonstrated that delta-tocotrienol could inhibit NSCLC cells proliferation, invasion and induce apoptosis by down-regulation of the Notch-1 signaling pathway. Using microRNA microarray and microRNA transfection, our findings further suggest that delta-tocotrienol is a non-toxic activator of miR-34a which can inhibit NSCLC cell proliferation, induce apoptosis, and inhibit invasion. Last but not the least, We observed that …
