Sulfated Macromolecules in Early Embryos of Limnaea

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1976
Abstract Molluscan Embryo, Sulfated Acid Mucopolysaccharide, Sulfated Protein An attempt has been made to partially characterize the substance responsible for the rhythmic incorporation of 35S (inorganic sulfate) in the course of the cell cycle in early Limnaea embryos.

Sulfated and Phosphorylated Agarose as Biomaterials for a Biomimetic Paradigm for FGF-2 Release [PDF]

Biomimetics
Cardiovascular diseases such as myocardial infarction or limb ischemia are characterized by regression of blood vessels. Local delivery of growth factors (GFs) involved in angiogenesis such as fibroblast blast growth factor-2 (FGF-2) has been shown to ...

A subclass of proteins and sulfated macromolecules secreted by AtT-20 (mouse pituitary tumor) cells is sorted with adrenocorticotropin into dense secretory granules. [PDF]

Journal of Cell Biology, 1983
The AtT-20 cell, a mouse pituitary tumor line that secretes adrenocorticotropin and beta-endorphin, sorts the proteins it externalizes into two exocytotic pathways. Cells that are labeled with [35S]methionine or [35S]sulfate can be shown to transport three acidic polypeptides (65,000, 60,000, and 37,000 mol wt) and at least two sulfated macromolecules ...

Sulfated modification, characterization and bioactivities of an acidic polysaccharide fraction from an edible mushroom Pleurotus eous (Berk.) Sacc.

Heliyon, 2021
The acidic fraction (P3a) of Pleurotus eous was successfully sulfated by sulphur trioxide-pyridine complex method. The effect of sulfate modification (SP3a) on the structure, physicochemical properties and in vitro biological activity of P3 was studied ...

Sulfate Incorporation into Macromolecules Produced by Cultured Oviductal Epithelium [PDF]

Biology of Reproduction, 1981
Oviductal secretions contribute to the environment in which sperm capacitation, fertilization, and early embryo development occur. This laboratory and others have demonstrated that major macromolecular secretions of the oviduct are sulfated. Oviductal epithelial cell cultures in the presence of [355) -sulfate were used to evaluate the uptake and ...
