High impact information on Pteridium

• Carcinogenicity of tannin and tannin-free extracts of bracken fern (Pteridium aquilinum) in rats [1].
• Quercetin, a rat intestinal and bladder carcinogen present in bracken fern (Pteridium aquilinum) [2].
• Our previous work with primary bovine fibroblasts demonstrated that quercetin, a potent mutagen found in high levels in bracken fern (Pteridium aquilinum), arrested cells in G1 and G2/M, in correlation with p53 activation [3].
• Nuclear bodies about 250 nm in diameter, and with a strong affinity for uranium and acriflavine, appear in the nuclei of maturing egg cells of Pteridium [4].
• Physiological parameters affecting reactivated ciliary beat in spermatozoids of braken fern (Pteridium aquilinum) were studied using a Triton/glycerol permeabilized cell model system [5].

Anatomical context of Pteridium

• Enhanced activity of ornithine decarboxylase of the ileum in rats by bracken fern (Pteridium aquilinum) [6].
• Previous work with primary human keratinocytes demonstrated that quercetin, a potent mutagen found in high levels in bracken fern (Pteridium aquilinum), arrested cells in G1 with concomitant elevation of the cyclin-dependent kinase inhibitor (cdki) p27Kip1 [7].

Associations of Pteridium with chemical compounds

• Identification of carcinogenic tannin isolated from Bracken fern (Pteridium aquilinum) [8].
• Pteroside A2--a new illudane-type sesquiterpene glucoside from pteridium caudatum L. Maxon, and the spectrometric characterization of caudatodienone [9].
• Chemical and toxicological studies on bracken fern, Pteridium aquilinum var. latiusculum II. Structures of pterosins, sesquiterpenes having 1-indanone skeleton [10].
• Studies on Pteridium aquilinum var. latiusculum, IV. Isolation of three p-hydroxystyrene glycosides and an efficient method for the isolation of ptaquiloside, an unstable bracken carcinogen [11].
• Polioencephalomalacia (PEM) was induced in sheep, with an overall incidence of 63 per cent, using local bracken fern (Pteridium esculentum) rhizomes as a source of thiaminase type 1 and pyridine as a basic cosubstrate [12].
