Magnesium (Mg2+) potentiated the anti-vesicular stomatitis virus (VSV) activity of poly r(A-U) or poly r(G-C) and the anti-HIV-1 activity of poly r(A-U). Mg2+ did not affect the anti-VSV activity of poly (rI).poly (rC), poly (dA-dT).poly (dA-dT) or…
When Mg2+ or ethidium bromide (EB) were combined with poly r(A-U) at a ligand/ribonucleotide ratio of 1/4, the antiviral activity of the Mg2+ and EB increased 136-fold and 154-fold. Eriochrome Blue SE was employed to visualize the subcellular…
The current study has documented changes in the ultrastructure as well as in the intranucleolar distribution of rDNA and rRNA in RT4 (human transitional cell bladder carcinoma) cell nucleoli following a 3-h exposure to toxic doses of 50 microM…
