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…
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…
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…
