Analysis of Hyaluronan Synthase Activity
2014Hyaluronan (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.

Hyaluronan synthase expression in ovarian cancer
Oncology Reports, 2004To determine if the immunohistochemical expression of hyaluronan synthase (HAS) correlates with the clinicopathological manifestations or clinical outcomes of ovarian carcinoma, sections of tumor tissue from 33 ovarian cancer patients were immunostained by the avidin-biotin-peroxidase complex method using anti-HAS1, anti-HAS2, anti-HAS3 and anti-CD44 ...

Hyaluronan Synthases Posttranslational Regulation in Cancer
2014Hyaluronan (HA) is a critical component of cancer microenvironment that is known to increase tumor progression and aggressiveness. The synthesis of HA starts from the cytosolic precursors UDP-N-acetylglucosamine and UDP-glucuronic acid. These two sugar nucleotides have several functions in addition to glycoconjugate synthesis and glucuronidation ...

Molecular Cloning of Human Hyaluronan Synthase
Biochemical and Biophysical Research Communications, 1996We report here the cDNA sequence of human hyaluronan synthase. The cDNA clone was isolated from a human fetal brain cDNA library by screening with a DNA probe generated from the coding sequence of murine hyaluronan synthase. It contains a 2107 bp cDNA insert which is composed of a 1629 bp open reading frame and a short segment of the 3'-untranslated ...

Phosphorylation of Thr328 in hyaluronan synthase 2 is essential for hyaluronan synthesis
Biochemical and Biophysical Research Communications, 2020Hyaluronan synthase 2 (HAS2) is an integral membrane protein composed of multi-membrane-spanning regions and a large intracellular loop (HAS2-loop). We previously examined the effect of phorbol 12-myristate 13-acetate (PMA) and/or 4-methylumbelliferone (4-MU) on the synthesis of hyaluronan (HA) in human skin fibroblasts and found that TPA and 4-MU have

The Hyaluronan Synthase Catalyzes the Synthesis and Membrane Translocation of Hyaluronan
Journal of Molecular Biology, 2012Hyaluronan (HA), an extracellular linear polysaccharide of alternating N-acetyl-glucosamine and glucuronic acid residues, is ubiquitously expressed in vertebrates, where it affects a broad spectrum of physiological processes, including cell adhesion, migration and differentiation. The HA polymer is synthesized on the cytosolic side of the cell membrane

Hyaluronan and hyaluronan synthases expression and localization in embryonic mouse molars
Journal of Molecular Histology, 2016Hyaluronan (HA) and hyaluronan synthases (HASs) have been shown to play critical roles in embryogenesis and organ development. However, there have not been any studies examining HA and HAS expression and localization during tooth development. The present study was designed to investigate the expression of HA and three isoforms of HASs (HAS1, 2, 3) in ...

Hyaluronan synthases and hyaluronidases in nasal polyps
European Archives of Oto-Rhino-Laryngology, 2015Nasal polyps (NPs) are benign lesions of nasal and paranasal sinuses mucosa affecting 1-4 % of all adults. Nasal polyposis affects the quality of patient's life as it causes nasal obstruction, postnasal drainage, purulent nasal discharge, hyposmia or anosmia, chronic sinusitis, facial pain and snoring.

Hyaluronan synthase expression in pleural malignant mesotheliomas
Virchows Archiv, 2005Hyaluronan (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 (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 ...
