Hyaluronan Synthases in Normal and Regenerating Joint Cartilage

Cells Tissues Organs, 2003
Repair of full thickness joint cartilage defects is within reach of routine clinical practice. The quality of regenerating hyaline cartilage, however, is difficult to assess. Synthesis of an extracellular matrix with high hyaluronan content is crucial for its metabolic and functional properties.

A Nonradioactive Method to Measure Hyaluronan Synthase Activity

2021
Hyaluronan (HA) is a component of the extracellular matrix that is involved in many physiological and pathological processes. As HA modulates several functions (i.e., cell proliferation and migration, inflammation), its presence in the tissues can have positive or negative effects.

Regulation of hyaluronan synthases in mouse uterine cervix

Biochemical and Biophysical Research Communications, 2005
We examined the expression pattern of hyaluronan synthase (HAS) mRNAs in the uterine cervix of pregnant mice. The expression levels of HAS-1 and -2 mRNAs peaked at delivery, whereas that of HAS-3 mRNA peaked on the 15th day of pregnancy. The regulation of HAS mRNA expression was examined in pregnant mouse uterine cervical fibroblasts. The expression of

Hyaluronan Synthase Assay

2009
Hyaluronan (HA) is a polysaccharide composed of repeating GlcNAcβ(1 → 4)- GlcUAβ(1 → 3) disaccharide units. This polysaccharide has a molecular mass ranging from 103 to 107 Da, depending on the tissue source and physiological conditions. Three members of the HA synthase family, HAS1, HAS2 and HAS3, have been thus far identified in a wide variety of ...

Hyaluronan synthase expression in pleural malignant mesotheliomas

Virchows Archiv, 2005
Hyaluronan (HA) is thought to play several important roles in tumor growth, tumorigenicity, and tumor dissemination and metastasis. Recently, three isoforms of hyaluronan synthase (HAS) have been cloned. Our objective was to determine which of the HAS isoforms were expressed in pleural malignant mesotheliomas, the most representative lesion of HA ...

Hyaluronan Synthases, Hyaluronan and Its CD44 Receptors in the Posterior Segment of Rabbit Eye

Ophthalmologica, 2005
To understand the possible roles of the hyaluronan synthetase (HAS)/hyaluronan (HA)/CD44 signaling system in the posterior eye segment, we investigated the expression of rabbit HAS isoforms and CD44 mRNA by RT-PCR and the level of HA by using HA assay and immunohistochemistry. HA was detectable in vitreous, retina and choroid.

Exploiting the diversity of streptococcal hyaluronan synthases for the production of molecular weight–tailored hyaluronan

Applied Microbiology and Biotechnology, 2019
The molecular weight (Mw) of hyaluronic acid (HA) determines its suitability for medical and cosmetic applications. Here, we characterize in vitro and in vivo HA synthesis of streptococcal HA synthases (HASs) with a special focus on HA Mw. To date, four streptococcal HA producers are described (Streptococcus equi subsp. equi, S.

Hyaluronan Synthase-1, -2, and -3

2002
Hyaluronan (HA) is a high-molecular-weight linear polysaccharide composed of β-1,4-linked repeating disaccharides of glucuronic acid β-1,3-linked to N- acetylglucosamine. It is found in the extracellular matrices of most vertebrate tissues and in the capsules of certain bacterial pathogens.
