Matrix: a complex amalgam of structures and functions in tumor microenvironment

FEBS Open Bio, Volume 15, Issue 10, Page 1552-1569, October 2025.
The matrix is a dynamic, intricate three‐dimensional mesh of biomolecules with both structural and functional properties. This review deals with the complexity of this ‘molecular amalgam’ in the tumor microenvironment and highlights its importance in the maintenance and evolution of tumors by describing certain matrix biomolecules, such as ...

Characterization of the Lipopolysaccharide from a \u3cem\u3eRhizobium phaseoli\u3c/em\u3e Mutant that is Defective in Infection Thread Development [PDF]

, 1987
The lipopolysaccharide (LPS) from a Rhizobium phaseoli mutant, CE109, was isolated and compared with that of its wild-type parent, CE3. A previous report has shown that the mutant is defective in infection thread development, and sodium dodecyl sulfate ...

Molecular Evolution and Gene Diversity of Dermatan Sulfate Sulfotransferases in Ascidians

Proteoglycan Research, Volume 3, Issue 4, October 2025.
ABSTRACT Ascidians (Chordata, Tunicata) are model organisms for studying molecules, particularly sulfated glycosaminoglycans (GAGs), due to their phylogenetic proximity to vertebrates and unique GAG variants. Over‐sulfated dermatan sulfate (DS) contributes to proteoglycan diversity and cellular processes in metazoans.

Elemental biochemical analysis of the polysaccharides in the extracellular matrix of the yeast Saccharomyces cerevisiae [PDF]

, 2015
In yeast multicellular aggregates, such as biofilms and colonies, cells are supported by a yeast extracellular matrix (yECM) of glycosidic nature, the composition of which is mostly unknown.

The Pathophysiological Functions of Heparanases: From Evolution, Structural and Tissue‐Specific Perspectives

The FASEB Journal, Volume 39, Issue 17, 15 September 2025.
Heparanase 1 (HPSE1) and Heparanase 2 (HPSE2) exhibit opposing expression patterns and functions in pathological contexts, such as cancer. Here, we describe their specific expression in immune cells and their implications in skin diseases. Although they are structurally similar and considered to be ‘cousins’, we found no common ancestor and that HPSE2 ...

Partial characterization and anticoagulant activity of a heterofucan from the brown seaweed Padina gymnospora [PDF]

, 2005
The brown algae Padina gymnospora contain different fucans. Powdered algae were submitted to proteolysis with the proteolytic enzyme maxataze. The first extract of the algae was constituted of polysaccharides contaminated with lipids, phenols, etc ...

Lipopolysaccharide (LPS, endotoxin) of Proteus bacteria-chemical structure, serological specificity and the role in pathogenicity [PDF]

, 2008
Lipopolysaccharides (LPS) of Gram-negative bacteria are composed of three regions: О-specific chain (OPS), the core oligosaccharide and lipid A. All three regions of Proteus LPS were studied. The differences in the structure of OPS serve as the basis
