Growth factor PDGF-BB stimulates cultured cardiomyocytes to synthesize the extracellular matrix component hyaluronan. [PDF]
Hyaluronan (HA) is a glycosaminoglycan located in the interstitial space which is essential for both structural and cell regulatory functions in connective tissue.

The purpose of this study was to illuminate the mechanism by which Schizonepeta tenuifolia Briq. (ST) ethanolic extract prevents skin photoaging in HR-1 hairless mice (HR-1). The ST ethanolic extract alleviated wrinkle formation, epidermal skin thickness,

Expression of hyaluronan synthases in articular cartilage
To investigate the mRNA expression profiles of three mammalian hyaluronan synthases (HAS1, HAS2 and HAS3) in chondrocytes from normal (undiseased) animal cartilage and osteoarthritic human cartilage maintained in experimental culture systems and exposed to catabolic or anabolic stimuli provided by cytokines, growth factors and retinoic acid ...

Hyaluronan Synthase 1: A Mysterious Enzyme with Unexpected Functions [PDF]
Hyaluronan synthase 1 (HAS1) is one of three isoenzymes responsible for cellular hyaluronan synthesis. Interest in HAS1 has been limited because its role in hyaluronan production seems to be insignificant compared to the two other isoenzymes, HAS2 and HAS3, which have higher enzymatic activity.

A Connecting Link between Hyaluronan Synthase 3-Mediated Hyaluronan Production and Epidermal Function [PDF]
Hyaluronan (HA), an essential component of the extracellular matrix of the skin, is synthesized by HA synthases (HAS1-3). To date, epidermal HA has been considered a major player in regulating cell proliferation and differentiation. However, a previous study reported that depletion of epidermal HA by Streptomyces hyaluronidase (St-HAase) has no ...

Molecular Identification of a Putative Human Hyaluronan Synthase [PDF]
To identify the putative mammalian hyaluronan synthase, we cloned a human cDNA that is related to the Streptococcus hyaluronan synthase (HasA) and the Xenopus developmental protein DG42 which has been shown to have chitin synthase activity. The cDNA, for which we propose the name Has2, encodes a novel protein with a predicted molecular mass of 63.6 kDa.

Hyaluronan synthase 2 expressed by cancer-associated fibroblasts promotes oral cancer invasion
Background Hyaluronan synthases (HAS) control the biosynthesis of hyaluronan (HA) and critically modulate the tumor microenviroment. Cancer-associated fibroblasts (CAFs) affect the progression of a tumor by remolding the matrix.
