Hyaluronan-Arginine Enhanced Interaction Emerges from Distinctive Molecular Signature with Improved Electrostatics and Side-Chain Specificity [PDF]

open access: yesarXiv, 2023
Hyaluronan, a sugar polymer found outside the plasma membrane, is a critical component of the extracellular matrix (ECM) scaffold. Hyaluronan's length and moderate negative charge aid in ECM entanglement and solubility. This allows it to effectively foster gel-like conditions, which are critical for supporting and protecting cells in various tissues ...

Suppression of Aggregation in Natural-Semiflexible/Flexible Polyanion Mixtures, and Direct Check of the OSF Model using SANS [PDF]

open access: yesEurophysics Letters (EPL) 83 (2008) 48002, 2009
Aggregation and other interactions are suppressed for a biological semiflexible polyelectrolyte, hyaluronan (HA), when it is embedded in a mixture with another negatively charged and flexible polyelectrolyte chain, sodium polystyrene sulfonate. We see directly HA only in the mixture using Small-Angle Neutron Scattering, isotopic labelling and contrast ...

The Influence of Hofmeister Series Ions on Hyaluronan Swelling and Viscosity

open access: yesMolecules, 2008
The dissolution of hyaluronan in water leads to its degradation, and as a resultits molecular weight decreases. The degradation of hyaluronan is mainly influenced bytemperature, solution composition, and also its pH.

Beads on a string: Structure of bound aggregates of globular particles and long polymer chains [PDF]

open access: yesSoft Matter 11, 8092-8099 (2015), 2015
Macroscopic properties of suspensions, such as those composed of globular particles (e.g., colloidal or macromolecular), can be tuned by controlling the equilibrium aggregation of the particles. We examine how aggregation -- and, hence, macroscopic properties -- can be controlled in a system composed of both globular particles and long, flexible ...

Hyaluronan-CD44 interaction promotes microRNA signaling and RhoGTPase activation leading to tumor progression. [PDF]

open access: yes, 2012
A hallmark of all solid tumor malignancies is the ability to invade the surrounding tissue and/or metastasize to distant sites. Tumors cells have altered signaling pathways which that to cytoskeleton activation and migration.

Phospholipids and Hyaluronan: From Molecular Interactions to Nano- and Macroscale Friction

open access: yesColloids and Interfaces, 2022
Phospholipids and hyaluronan are two key biomolecules that contribute to the excellent lubrication of articular joints. Phospholipids alone and in combination with hyaluronan have also displayed low friction forces on smooth surfaces in micro- and ...

Influence of hyaluronan on endometrial receptivity and embryo attachment in sheep [PDF]

open access: yes, 2017
An increasing number of reports suggests a role of hyaluronan (HA) in female reproduction and interest in its application in assisted reproduction is rising.

Size Matters: Molecular Weight Specificity of Hyaluronan Effects in Cell Biology

open access: yesInternational Journal of Cell Biology, 2015
Hyaluronan signaling properties are unique among other biologically active molecules, that they are apparently not influenced by postsynthetic molecular modification, but by hyaluronan fragment size. This review summarizes the current knowledge about the

Connective tissue growth factor mediates bone morphogenetic protein 2-induced increase in hyaluronan production in luteinized human granulosa cells

open access: yesReproductive Biology and Endocrinology, 2022
Background Hyaluronan is the main component of the cumulus-oocyte complex (COC) matrix, and it maintains the basic structure of the COC during ovulation.
