Electron microscopy of pokeweed leaf cells infected with pokeweed mosaic virus

Virology, 1969
Abstract Cytoplasmic inclusions associated with pokeweed mosaic virus (PMV) infection are similar to those which have been reported for other long, flexuous rod-shaped viruses. Cylindrical inclusions and their derivatives such as circular inclusions, tubes, laminated aggregates, bundles, and pinwheels are all associated with PMV infection.

Histamine contamination of pokeweed mitogen

Journal of Immunological Methods, 1982
The histamine content of commercial preparations of pokeweed mitogen was measured by amino acid analysis technique, automated fluorometry, and bioassay employing the guinea pig ileum. Ten samples from 5 companies were examined and found to contain between 0.026 micrograms and 167.5 micrograms of histamine per ml of solution. The protein content of 9 of

Common Pokeweed

Weed Technology, 1994
Phytolaccaceae, virtually a tropical family, encompasses from 15 to 18 genera (11), usually herbs, but also a few tropical trees and shrubs (13). Of the 25 species in the genus Phytolacca (11), only one is represented in eastern North America (1).

Enhanced tumor imaging with pokeweed mitogen

Nuclear Medicine and Biology, 1993
Traditional tumor imaging with biotracer techniques relies solely on the target specificity of the biomolecule. We hypothesize that specific imaging is possible by altering the rate of tissue clearance (both normal and aberrant) of any given radiotracer.

Carbohydrate-binding specificity of pokeweed mitogens

Biochimica et Biophysica Acta (BBA) - General Subjects, 1978
The carbohydrate-binding specificity of two pokeweed (Phytolacca americana) mitogens (Pa-1 and Pa-2) was investigated by means of hemagglutination inhibition assays and the quantitative inhibition of the binding of 125I-labeled lectins to human erythrocytes using various oligosaccharides, glycopeptides and glycoproteins as hapten inhibitors.

Anti-pokeweed mitogen antiserum inhibits and enhances blastogenesis of mononuclear cells induced by pokeweed mitogen

Agents and Actions, 1988
The interaction between pokeweed mitogen (PWM) and peripheral blood mononuclear cells (PBMC) was investigated using rabbit anti-PWM antiserum (anti-PWM) and 125I-PWM. Incubation of PBMC with PWM in the presence of anti-PWM resulted in an inhibition of the mitogenic effect of PWM.

Pokeweed Antiviral Protein and Its Applications

2000
The genus Phytolacca produces a number of proteins that have antiviral properties. These antiviral proteins are ribosome-inactivating proteins (RIPs) which remove a single adenine from a highly conserved, surface-exposed, stem-loop structure in the large rRNA of eukaryotic and prokaryotic ribosomes.

Identification of the Pokeweed Mitogen in Africa

Nature, 1967
IN 1960, Nowell1 first described a plant lectin from Phaseolus vulgaris—phytohaemagglutinin, which possessed mitogenic activity for human peripheral blood lymphocytes, that is, the ability to transform the resting lymphocyte into blast like cells. Subsequently, a second phytomitogen was reported2 in saline extracts of the plant Phytolacca americana—the

A Geography of Pokeweed

Annals of the Missouri Botanical Garden, 1952
The plants we call weeds stand apart from their truly wild and truly tame fellows because of their special ability to establish themselves in artificial habitats. In spite of indifference or active repression by man, they have been able to thrive and multiply with the advance of civilization.

Pokeweed antiviral protein: Ribosome inactivation and therapeutic applications

Pharmacology & Therapeutics, 1992
Pokeweed antiviral protein (PAP) is a ribosome-inactivating protein (RIP) that inactivates ribosomes by the removal of a single adenine from ribosomal RNA. The studies summarized in our review concern the nature and application of this novel therapeutic agent. We describe how researchers continue to elucidate the structure and biologic activity of RIPs.
