Isolation of Polysaccharides Sulfated during Early Embryogenesis in Fucus

Actin Localization during Fucus Embryogenesis.

Embryogenesis in the Fucales serves as a model system for studying the acquisition of cellular and developmental polarity. Fertilized eggs bear no asymmetry, yet within 16 hours, a developmental axis is formed and the unicellular zygote germinates in accordance with this axis. Microfilaments (actin) play a crucial role in establishing the axis as evidenced by the inhibitory effects of cytochala...

Dynamics of cell wall assembly during early embryogenesis in the brown alga Fucus

Zygotes from Fucus species have been used extensively to study cell polarization and rhizoid outgrowth, and in this model system cell wall deposition aligns with the establishment of polarity. Monoclonal antibodies are essential tools for the in situ analysis of cell wall glycans, and here we report the characteristics of six monoclonal antibodies to alginates (BAM6-BAM11). The use of these, in...

Effects of sulfated polysaccharides on tumour biology.

Sulfated polysaccharides can act not only as anticoagulants but also as tumour inhibitors. Recent studies suggest that sulfated polysaccharides could affect tumour cells directly. Sulfated polysaccharides could inhibit the metastasis and proliferation of tumour cells by binding to growth factors and cell adhesion molecules. Moreover, sulfated polysaccharides could inhibit heparanase, which clea...

[Neuroprotective effects of sulfated polysaccharides from seaweed].

Currently, neurodegenerative diseases (NDD) occupy a significant place in the structure of disease of the elderly, which dictates the need to find new and effective treatment and prevention of this pathology. At the heart of NDD development is a violation of the metabolism and the conformational change of cellular proteins with subsequent accumulation and aggregation of their in certain groups ...
