The present study showed that vitamin E, although ineffective by itself, was able to potentiate the ability of selenium to inhibit the development of mammary tumors induced by dimethylbenz(a)anthracene (DMBA) in rats. Animals were maintained on a high-polyunsaturated fat (20% corn oil) diet in order to increase the degree of oxidant stress; additional(More)
Expression of the platelet derived growth factor (PDGF) B-chain, the product of the c-sis proto-oncogene, is regulated both at the transcriptional and translational level. Previous studies have shown that the long 5' untranslated region (UTR) of the c-sis mRNA strongly inhibits synthesis of the PDGF-B chain. However, the assignments of down-regulatory(More)
Highly purified nuclear and cytoplasmic RNAs were obtained from Tetrahymena thermophila BVII containing only a minimal amount of cross-contamination. In the nuclear RNA fraction we have detected at least 6 distinct snRNAs. Some of the RNA species showed microheterogeneity. SnRNAs of Tetrahymena thermophila are very similar to rat snRNAs, as far as length is(More)
