The functions of microRNAs (miRNAs) as either oncogenes or tumor suppressors in regulating cancer-related events have been established. We analyzed the alterations in the miRNA expression profile of the glioma cell line U-251 caused by ionizing radiation (IR) by using an miRNA array and identified several miRNAs whose expression was significantly affected(More)
Shikonin, a naphthoquinone derivative, has been shown to possess antitumor activity. In the present study, the effects of shikonin and its analog, β,β-dimethylacrylshikonin, were investigated as radiosensitizers on the human colon cancer cell line, HCT-116. Shikonin and, to a greater extent, its analog-induced apoptosis of HCT-116 cells further(More)
