In vitro evaluation of wound healing potential of sulfated galactans from red alga Gracilaria fisheri in fibroblast cells [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2021
Red alga Gracilaria species have been reported various to exhibit significant pharmacological activities. In this study, sulfated galactans (SG) from G. fisheri was investigated for its potential activity in wound healing using in vitro approach.

Is the antithrombotic effect of sulfated galactans independent of serpin? [PDF]

Journal of Thrombosis and Haemostasis, 2014
Sulfated galactans are polysaccharides with heterogeneous structures that frequently show anticoagulant activity. Their anticoagulant mechanisms are complex and distinct from those observed for heparin. Sulfated galactans act through a combination of effects involving serpin-dependent and serpin-independent mechanisms. Interestingly, these polymers can

Is there a correlation between structure and anticoagulant action of sulfated galactans and sulfated fucans? [PDF]

Glycobiology, 2002
We attempted to identify the specific structural features in sulfated galactans and sulfated fucans that confer anticoagulant activity. For this study we employed a variety of invertebrate polysaccharides with simple structures composed of well-defined units of oligosaccharides.

S-Assimilation Influences in Carrageenan Biosynthesis Genes during Ethylene-Induced Carposporogenesis in Red Seaweed Grateloupia imbricata

Marine Drugs, 2022
The synthesis of cell-wall sulfated galactans proceeds through UDP galactose, a major nucleotide sugar in red seaweed, whilst sulfate is transported through S-transporters into algae.

Trehalose as a Possible Precursor of the Sulfated L-Galactan in the Ascidian Tunic [PDF]

Journal of Biological Chemistry, 1995
Among sulfated polysaccharides, those in the tunic of ascidians are unique: their major constituent sugar is galactose, which occurs exclusively in the L-enantiomeric form. Incorporation of D-[14C]glucose into tunic slices in vitro revealed that the cells epimerize D-glucose into L-galactose during biosynthesis of the sulfated polysaccharides.

Sulfated galactans from red seaweeds and their potential applications [PDF]

, 2018
Red seaweeds (Rhodophyta) produce a variety of sulfated galactans in their cell wall matrix and intercellular space, contributing up to 50-60 % of their total dry weight.

Structure, biology, evolution, and medical importance of sulfated fucans and galactans [PDF]

Glycobiology, 2008
Sulfated fucans and galactans are strongly anionic polysaccharides found in marine organisms. Their structures vary among species, but their major features are conserved among phyla. Sulfated fucans are found in marine brown algae and echinoderms, whereas sulfated galactans occur in red and green algae, marine angiosperms, tunicates (ascidians), and ...

A Repeating Sulfated Galactan Motif Resuscitates Dormant Micrococcus luteus Bacteria [PDF]

Applied and Environmental Microbiology, 2018
ABSTRACT Only a small fraction of bacteria can autonomously initiate growth on agar plates. Nongrowing bacteria typically enter a metabolically inactive dormant state and require specific chemical trigger factors or signals to exit this state and to resume growth.

Sulfated fucans and a sulfated galactan from sea urchins as potent inhibitors of selectin-dependent hematogenous metastasis [PDF]

Glycobiology, 2018
Metastasis is responsible for the majority of cancer-associated deaths, though only a very small number of tumor cells are able to efficiently complete all the steps of that process. Tumor cell survival in the bloodstream is one of the limiting aspects of the metastatic cascade.

Revisiting the life cycle of Margalefidinium polykrikoides Group III. [PDF]

J Phycol
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.
