There was a higher HAS1 and HAS2 reactivity and lower HAS3 reactivity in the PCOS endometrium compared to women with regular menstrual cycles in the proliferative phase.
hyaluronic acid synthase-1 promotes malignant transformation via epithelial-to-mesenchymal transition, micronucleation and centrosome abnormalities
our study indicated a HAS1-miR214-SOX-4 pathway in regulating the growth and metastasis of Esophageal squamous cell carcinoma (ESCC) , providing a promising target for ESCC therapy
Reduced expression of HAS1 and HAS2 is associated with melanoma progression and suggests that HAS1 and HAS2 have a prognostic significance in cutaneous melanoma.
Regulation of Hyaluronan (HA) Metabolism Mediated by HYBID (Hyaluronan-binding Protein Involved in HA Depolymerization, KIAA1199) and HA Synthases in Growth Factor-stimulated Fibroblasts.
The minor allele genotypes of HAS1 SNPs are significantly more frequent in MM, WM, CLL and in affected members of a monoclonal gammopathy-prone family than they are in breast cancer, sporadic MGUS or healthy donors
transcriptional regulation of the HAS and HAS2-antisense RNA 1 genes, was analyzed.
HAS1 is the main enzyme responsible for hyaluronan production by normal keratinocytes.
The HAS1-dependent coat is induced by inflammatory agents and glycemic stress, mediated by altered presentation of either CD44 or hyaluronan, and can offer a rapid cellular response to injury and inflammation.
Among the genes affected by FAK or HAS3 inhibition were genes, playing role in apoptosis, cell cycle regulation, adhesion, transcription, heatshock and WNT pathways.
Inverse expression of hyaluronidase 2 and hyaluronan synthases 1-3 is associated with reduced hyaluronan content in malignant cutaneous melanoma.
aberrant intronic HAS1 splicing in multiple myeloma patients may rely on intronic HAS1 deletions and mutations that are frequent in MM patients but absent from healthy donors
TGF-beta1 up-regulation of HAS1 transcription was mediated via Smad3 but not Smad2, while HAS1 induction by IL-1beta was Sp3, not Sp1, dependent.
Hyaluronan synthase 1 (HAS1) requires higher cellular UDP-GlcNAc concentration than HAS2 and HAS3
HA chains synthesized by HAS1 and HAS2 contribute to outflow resistance, while hyaluronan produced by HAS3 does not appear to play a significant role.
analysis of changes in cervical glycosaminoglycan composition during normal pregnancy and preterm birth: Has1 is expressed in preterm birth, while Has2 is induced at term
this study provides strong evidence that HAS1-driven Hyaluonan-synthesis is a target of estradiol in human vascular smooth muscle cells
HYAL-1 and HAS1 expression predicted bladder cancer metastasis, and HYAL-1 expression also predicted disease-specific survival.
Hyaluronan synthases (HAS1-3) and hyaluronidases (HYAL1-2) in the accumulation of hyaluronan in endometrioid endometrial carcinoma
Data show that a significant in expression levels of HA synthases (HASs) and hyaluronidases (Hyals) was observed in vitro on stimulation of epithelial ovarian carcinoma cells by gonadotropins.
The HA concentration in follicular fluids increased during atresia and HAS1 may be the dominant HAS protein in theca cells to produce HA in pig ovaries.
deficiency impeded post-natal formation of the retrocalcaneal bursa, implicating HAS1 in regulating hyaluronan metabolism by cells lining the bursal cavity
In the present study, we examined expression patterns of Has1, -2, -3 mRNA in developing mouse molar and incisor tooth germs from embryonic day (E) 11.5 to postnatal day (P) 7, focusing on Hertwig's epithelial root sheath (HERS) and the apical bud in particular. Has1 mRNA expression was not detected in all tooth germs examined
HAS1 was significantly upregulated at the level of gene expression during muscle hypertrophy.
Selective loss of Has1 and Has3 leads to a proinflammatory milieu that favors recruitment of neutrophils and other inflammation-related changes in the dermis.
repression of HA-accumulation by both COX-2 selective and non-selective COX inhibition implicates COX-2 in the regulation of HA synthesis via stimulation of HAS1 and HAS2 expression in vivo
proper regulation of the expression of each HAS isoform is required for optimal malignant transformation and tumor growth
expressed throughout the gastrulating embryo
Has-1 transduced ASMCs accumulated the greatest amount of HA containing ECM than the other transduced ASMCs.Confocal microscopy showed CD44 positive monocytes bound to hyaluronidase sensitive ECM in has-1 transduced ASMCs.
Hyaluronan or hyaluronic acid (HA) is a high molecular weight unbranched polysaccharide synthesized by a wide variety of organisms from bacteria to mammals, and is a constituent of the extracellular matrix. It consists of alternating glucuronic acid and N-acetylglucosamine residues that are linked by beta-1-3 and beta-1-4 glycosidic bonds. HA is synthesized by membrane-bound synthase at the inner surface of the plasma membrane, and the chains are extruded through pore-like structures into the extracellular space. It serves a variety of functions, including space filling, lubrication of joints, and provision of a matrix through which cells can migrate. HA is actively produced during wound healing and tissue repair to provide a framework for ingrowth of blood vessels and fibroblasts. Changes in the serum concentration of HA are associated with inflammatory and degenerative arthropathies such as rheumatoid arthritis. In addition, the interaction of HA with the leukocyte receptor CD44 is important in tissue-specific homing by leukocytes, and overexpression of HA receptors has been correlated with tumor metastasis. HAS1 is a member of the newly identified vertebrate gene family encoding putative hyaluronan synthases, and its amino acid sequence shows significant homology to the hasA gene product of Streptococcus pyogenes, a glycosaminoglycan synthetase (DG42) from Xenopus laevis, and a recently described murine hyaluronan synthase.
