Short-term effects of ethanol on human amnion cells were investigated by studying the cellular signaling processes and the replication of vesicular stomatitis virus. Treatment of human amniotic cells with ethanol transiently triggers the breakdown of

Experimental results suggest that protein kinase C (PK-C) may play a substantial role in the action of IFNs, but the precise biochemical pathway remains unknown. Recent evidences reveal the complexity of the mechanism of IFN-action and show that the

Association of protein kinase C (PKC) activity to the membrane fraction was observed in oxytocin treated human amnion cells (UAC). In addition, oxytocin was shown to induce an antiviral state and to inhibit multiplication of vesicular stomatitis viru

Human interferon-alpha (Hu-IFN alpha) and phorbol myristate acetate (PMA), a direct activator of protein kinase C (PK-C), induce the translocation of protein kinase C from the cytosol to the membrane fraction. By the use of transmission (TEM) and sca

The incorporation of labeled precursors into RNAs and proteins of isolated tobacco (Nicotiana tabacum L.) leaf protoplasts decreases with increasing osmotic pressure in the incubation medium. The incorporation of precursors into RNA and proteins is l

It has been shown in this experimental series that osmotic stress (plasmolysis induced by non-permeating plasmolytica), not mechanical or chemical injury, is the major factor which induces the large increase in the level of ribonuclease (RNAase) whic

Polyribosomes (polysomes), active in an amino acid incorporation system in vitro, were isolated from tobacco leaf protoplasts. A comparison of polysome profiles indicated that the polysome/monosome ratio is greatly decreased in isolated protoplasts a
Osmotic shock triggers an increase in ribonuclease level in protoplasts isolated from tobacco leaves

In protoplasts isolated from tobacco leaves and incubated in 0.7 M mannitol for 24 h, the ribonuclease (RNAase) level increased 12- to 15-fold during incubation. Various inhibitors of protein synthesis prevented or reduced the increase in RNAase acti

TMV-RNA synthesis was shown to be renewed in protoplasts isolated from TMV-infected Xanthi tobacco leaves in which virus synthesis has already slowed down or stopped. This was demonstrated by the use of isotope techniques in three different disease s
