Disease relevance of Amaranthus

• Effects of low dose aspirin (81 mg) on proliferating cell nuclear antigen and Amaranthus caudatus labeling in normal-risk and high-risk human subjects for colorectal cancer [1].
• Inactivation of betaine aldehyde dehydrogenase from Pseudomonas aeruginosa and Amaranthus hypochondriacus L. leaves by disulfiram [2].

High impact information on Amaranthus

• Structure of benzyl T-antigen disaccharide bound to Amaranthus caudatus agglutinin [3].
• A newly isolated lectin, Amaranthus caudatus agglutinin (also called amaranthin or ACA), which binds to the Thomsen-Friedenreich antigen (T-antigen) and its sialylated variants, was used as a histochemical probe for proliferating cells in sections of human colonic tissues [4].
• Betaine-aldehyde dehydrogenase from leaves of Amaranthus hypochondriacus L. exhibits an Iso Ordered Bi Bi steady state mechanism [5].
• Isolation and characterization of amaranthin, a lectin present in the seeds of Amaranthus caudatus, that recognizes the T- (or cryptic T)-antigen [6].
• The same predicted amino acid change in psbA was previously shown for an Amaranthus hybridus 'S' and 'R' biotypes which had, in addition, two silent nucleotide changes between the genes (Hirschberg, J. and McIntosh, L., Science 222, 1346-1349, 1983) [7].

Biological context of Amaranthus

• Antimicrobial peptides from Amaranthus caudatus seeds with sequence homology to the cysteine/glycine-rich domain of chitin-binding proteins [8].
• Marked modulation by phosphate of phosphoenolpyruvate carboxylase in leaves of Amaranthus hypochondriacus, a NAD-ME type C4 plant: decrease in malate sensitivity but no change in the phosphorylation status [9].
• We previously reported that the rate of photosynthesis decreased when C4 model plants prepared from Amaranthus cruentus leaves were subjected to sink-limited conditions by exposure to continuous light for a few days [10].
• Tumor cell proliferation and cyclooxygenase enzyme inhibitory compounds in Amaranthus tricolor [11].

Anatomical context of Amaranthus

• The receptor for Amaranthus leucocarpus lectin from CD-1 resident macrophages was purified with affinity chromatography with biotin labeled A. leucocarpus lectin and using avidin-agarose as affinity matrix [12].
• Like a few other Amaranthus lectins, these lectins were also inhibited by N-acetyl-D-galactosamine, fetuin and asialofetuin; they agglutinated human and different animal erythrocytes [13].

Associations of Amaranthus with chemical compounds

• Fructose-6-phosphate,2-kinase and fructose-2,6-bisphosphatase were separated on the basis of charge from leaves of C3 (spinach, lettuce, and pea) and C4 (sorghum and amaranthus) plants but not from rat liver--a tissue known to contain a bifunctional enzyme with both activities [14].
• 1. A wide range of purine bases, nucleosides and cyclic nucleotides were shown to induce betacyanin synthesis in Amaranthus seedlings [15].
• Aminophylline was shown to inhibit Amaranthus cyclic AMP phosphodiesterase activity [15].
• Molecular basis for multiple resistance to acetolactate synthase-inhibiting herbicides and atrazine in Amaranthus blitoides (prostrate pigweed) [16].
• The third compound with cytokinin activity in Amaranthus caudatus bioassay proved to be a simple phenolic compound with elemental composition C8H10O2 [17].

Gene context of Amaranthus

• A mutant of the NAD-malic enzyme-type C(4) plant, Amaranthus edulis, which lacks phosphoenolpyruvate carboxylase (PEPC) in the mesophyll cells was studied [18].
• Heterozygous mutants of Amaranthus edulis deficient in PEP carboxylase (PEPC) have been used to study the control of photosynthetic carbon assimilation [19].
• Heavy metals alter photosynthetic pigment profiles as well as activities of chlorophyllase and 5-aminolevulinic acid dehydratase (ALAD) in Amaranthus lividus seedlings [20].
• Elimination of POR expression correlates with red leaf formation in Amaranthus tricolor [21].
• A protein proteinase inhibitor was purified from a seed extract of amaranth (Amaranthus hypochondriacus) by precipitation with (NH4)2SO4, gel-filtration chromatography, ion-exchange chromatography, and reverse-phase high-performance liquid chromatography [22].

Analytical, diagnostic and therapeutic context of Amaranthus

• Surface soil, atmospherically deposited surface films on windows, and leaves of Amaranthus dubius were sampled at known distances from the roads and analyzed for lead (Pb), zinc (Zn), and cadmium (Cd) using flame atomic absorption spectrophotometry [23].
• We evaluated aspirin's effects on proliferating cell nuclear antigen (PCNA) immunohistochemistry and epithelial mucin histochemistry using the lectin, Amaranthus caudatus agglutinin (ACA) in crypt sections from rectal biopsies [1].
• Immobilization of Amaranthus leaf oxalate oxidase on alkylamine glass [24].
• Rapid techniques for the extraction of vitamin E isomers from Amaranthus caudatus seeds: ultrasonic and supercritical fluid extraction [25].
