HKH40A, the 8-methoxy analog of WMC79, is a synthetic agent with promising in vitro and in vivo antitumor activity, especially against solid tumors. However, molecular mechanisms underlying its antitumor effects are poorly understood. Here, we report that HKH40A markedly reduces the level of GRP78/BiP protein in cancer cell lines of various origin. In this(More)
The 579-nucleotide 5' untranslated region (5'UTR) of the Rhopalosiphum padi virus (RhPV) possesses a cross-kingdom internal ribosome entry site (IRES) activity that functions in insect, mammalian, and plant-derived in vitro translation systems, and six TAAG motifs within the DNA fragment encoding the RhPV 5'UTR were previously found to confer the RhPV 5'UTR(More)
