induces GADD45A expression and G1 arrest with SAPK/JNK activation in LNCap human prostate cancer cells.
A change in these pigment compositions could directly affect the wavelength bands used as the optimal NDI in our study as the most abundant diatom photosynthetic carotenoid, fucoxanthin
, has a broad absorption peak from 490 to 515 nm, whereas the important photoprotective carotenoid, diadinoxanthin, has a sharp peak centered at ~490 nm (Bricaud et al.
The products are mainly made in Southern Ireland and bottled in England, although the fucoxanthin
supplement is made in the US and packaged in the UK under Healtharena's Advanced Nutrition brand.
BROWN seaweed, used to flavour Asian soups and salads, contains a fat-burning compound called fucoxanthin
that helps weight loss.
Specifically, animal tests showed that a pigment in the seaweed called fucoxanthin
promotes weight loss.
Photopigment markers include chlorophyll b and lutein (chlorophytes), zeaxanthin, myxoxanthophyll, and echinenone (cyanobacteria), fucoxanthin
(diatoms), peridinin (dinoflagellates), and alloxanthin (cryptomonads).
In general these organisms have yellowish chromatophores (chlorophyll a and c and fucoxanthin
are the basic pigments) that never accumulate starch as a reserve, with differentiated flagella (when present), clear plasma, and a cell covering of small scales rich in structural detail, some of them mineralized, that may extend to varying degrees over the flagella.
These pigments include compounds that allow discrimination of cryptophytes (alloxanthin), diatoms (diatoxanthin), dinoflagellates (peridinin), cyanobacteria (zeaxanthin), filamentous cyanobacteria (myxoxanthophyll, oscillaxanthin), chlorophytes (lutein, Chl b, and derivatives), as well as chromophytes (chrysophytes, diatoms, some dinoflagellates; fucoxanthin
, Chl c).
Several characteristics in Andersen's ultrastructure data set including the girdle lamella, fucoxanthin
, and carotenoids appear to be randomized in the rRNA trees.
Higher concentrations of the diatom pigment marker, fucoxanthin
, were found in the high Callianassa densities, indicating higher standing stocks of diatoms.
