Nestin is one of the intermediate filaments abundantly produced in the developing central nervous system and somites in the embryonic stage. Nestin is also reportedly detected in gliomas/glioblastomas. We retested nestin expression in brain tumors having a range of malignancy grades using immunostaining. The intensity of nestin immunostaining roughly(More)
The prostaglandin-evoked cAMP production was studied in human neuroblastoma SK-N-BE(2)C cells during neuronal differentiation induced by all-trans retinoic acid. The incubation with 5 microM all-trans retinoic acid for 4-6 days promoted neurite outgrowth of cells. After differentiation, prostaglandin E(2) (PGE(2))-induced cAMP production was dramatically(More)
We analyzed the main disaccharide units of glycosaminoglycans synthesized by cardiac myxoma cells in vivo and in cell culture using high-performance liquid chromatography after 1-phenyl-3-methyl-5-pyrasolone labeling. Cardiac myxoma tissues contained large amounts of chondroitin-6-sulfate (46%) and hyaluronic acid (32%), along with some(More)
