Osteoporosis is a systemic skeletal disease that causes bone weakness and fragility. Consuming bone-beneficial nutrients through diet can prevent and treat osteoporosis. Acer palmatum (Japanese maple) leaves are used to make tea, but there have been few reports of their health benefits,
Osteogenic activity of six diarylheptanoids, acerogenin A (1), (R)-acerogenin B (2), aceroside I (3), aceroside B(1) (4), aceroside III (5) and (-)-centrolobol (6) and two phenolic compounds; (+)-rhododendrol (7) and (+)-cathechin (8), isolated from the stem bark of Acer nikoense (Nikko maple) was
We investigated the effects of acerogenin A, a natural compound isolated from Acer nikoense Maxim, on osteoblast differentiation by using osteoblastic cells. Acerogenin A stimulated the cell proliferation of MC3T3-E1 osteoblastic cells and RD-C6 osteoblastic cells (Runx2-deficient cell line). It
The availability of methods to fractionate non-green plastids and to prepare their limiting envelope membranes [Alban, Joyard & Douce (1988) Plant Physiol. 88, 709-717] allowed a detailed analysis of the biosynthesis of lysophosphatidic acid, phosphatidic acid, diacylglycerol and
2,2,2-Trichloroethyl 3,4-dichlorocarbanilate (SW26) is toxic for Acer pseudoplatanus cell cultures. It inhibited the cellular proton extrusion and depolarized the plasmalemma. In vitro, it inhibited the plasma membrane ATPase. SW 26 was also inhibitory to membrane ATPases of other origins-plant
A soluble enzyme system from suspension cultures of Acer pseudoplatanus L. converts d-glucose 6-phosphate to myoinositol. A Mg(2+)-dependent phosphatase, present in the crude extract, hydrolyzes the product of the cyclization, myoinositol monophosphate, to free myoinositol. Further purification of
In highly purified tonoplast fractions from Acer pseudoplatanus cells, the in vitro reversible phosphorylation of proteins affected only a restricted set of polypeptides. The phosphorylation process has been shown to be dramatically stimulated by calcium via the mediation of calmodulin as the
When an enzyme is bound to an insoluble polyelectrolyte it may acquire novel kinetic properties generated by Donnan effects. It the enzyme is homogeneously distributed within the matrix, a variation of the electrostatic partition coefficient, when substrate concentration is varied, mimics either
We re-examined data from a recent litter decay study to determine if additional insights could be gained to inform decomposition modeling. Rinkes et al. (2013) conducted 14-day laboratory incubations of sugar maple (Acer saccharum) or white oak (Quercus alba) leaves, mixed with sand (0.4% organic C
The methylation of cytoplasmic ribosomal RNA of cultured sycamore cells (Acer pseudoplatanus L.) was investigated. Labelled 17-S and 26-S rRNA were prepared from cells that had been incubated with either [32P]phosphate, [Me-3H]methionine or [Me-14C]methionine. Ion-exchange resin chromatography of
