A newly defined endothelial cell permeability structure, termed the vesiculo-vacuolar organelle (VVO), has been identified in the microvasculature that accompanies tumors, in venules associated with a...
Treatment of goldfish xanthophores with adrenocorticotropin (ACTH) or cyclic AMP (cAMP) induces the centrifugal movement of their pigment organelles from the center of the cells. Using purified xantho...
We reported previously that, in cultured goldfish xanthophores, dispersion of aggregated carotenoid droplets (CDs) requires the specific phosphorylation of the CD protein p57 by a cAMP-dependent prote...
