RNAseq of gingival fibroblasts exposed to cross-linked hyaluronic acid

ABSTRACT: Hyaluronic acid was proposed to support soft tissue recession surgery and guided tissue regeneration. Nevertheless, the molecular mechanisms through which hyaluronic acid modulates the response of the connective tissue cells remain elusive. To elucidate the impact of hyaluronic acid on the connective tissue cells, we employed bulk RNA sequencing to unravel the changes in the genetic signature gingival fibroblasts exposed to 1.6% cross-linked hyaluronic acid and 0.2% natural hyaluronic acid hyaluronic acid. Transcriptome-wide changes were modest, even when implementing a minimum of 1.5 log2 fold-change and a significance threshold of 1.0 -log10; only a dozenth gene was differentially expressed and ranked according to the Manhattan distance. Upregulated were PLK3, SLC16A6, IL6, HBEGF, DGKE, DUSP4, PTGS2, FOXC2, ATAD2B, NFATC2, and downregulated were MMP24 and PLXNA2. RT-PCR analysis supported the impact of hyaluronic acid on increasing expression of the selected gene panel. The findings from bulk RNA sequencing suggest that gingival fibroblasts only show a weak response when exposed to hyaluronic acid.

Synergistic potential of sulfated hyaluronic acid and dexamethasone

Project description:Both sulfated hyaluronic acid and dexamethasone are candidates for the functionalization of bone grafts as they were shown to enhance the differentiation of osteoblasts from bone marrow stromal cells in vitro and in vivo. However, the underlying mechanisms are not fully understood. Furthermore, studies combining different approaches to assess to synergistic potentials are rare. In this study, we aim gain insights into the mode-of-action of both sulfated hyaluronic acid and dexamethasone by a comprehensive analysis of the cellular fraction, released matrix vesicles and the extracellular matrix, combining classical biochemical assays with mass spectrometry-based proteomics and further supported by novel bioinformatical computation.

Surface stiffness, hydration, polydimethylsiloxane (PDMS), hyaluronic acid, biofilm and bacterial mobility, protein patterns.

Project description:By a global proteomic approach and phenotypic assays, we investigated the impact of surface stiffness on E. coli biofilm formation capacity. A global proteomic approach was used in order to identify the most abundant proteins for the comparison between E. coli adhesion in PDMS 9 kPa and 574kPa, (polydimethylsiloxane,), and between HA 44Pa and 2kPa (hyaluronic acid gels).

Pathogenesis of enamel-renal syndrome associated gingival fibromatosis: a proteomic approach

Project description:The enamel renal syndrome (ERS) is a rare disorder featured by amelogenesis imperfecta, gingival fibromatosis and nephrocalcinosis. Gingival fibromatosis is a hallmark of the disease; it is characterized by the accumulation of a collagen-rich, dense connective tissue and of mineral deposits throughout the gingiva. ERS is caused by biallelic mutations in the FAM20A gene encoding a pseudokinase, likely acting as an allosteric activator of FAM20C, the Golgi casein kinase. How mutations in FAM20A may modify the gingival connective tissue homeostasis and cause fibromatosis is currently unknown. Conditioned media of gingival fibroblasts (GF) obtained from four unrelated ERS patients carrying distinct mutations and three control subjects were used. Secretomic analysis identified 109 dysregulated proteins whose abundance had increased (69 proteins) or decreased (40 proteins) at least 1.5-fold compared to control GF. Gene Ontology (GO) analysis revealed biological processes significantly over-represented or under-represented in the ERS GF. Proteins over-represented were mainly involved in extracellular matrix organization, collagen fibril assembly, and biomineralization whereas those under-represented were extracellular matrix-associated proteins. Accordingly, GO disease analysis indicated un significant enrichment of tumoral angiogenesis and fibrosis.

Differential gene expression of human periodontium-derived mesenchymal stem cells

Project description:Mesenchymal stem cells (MSCs) isolated from human gingival tissue and periodontal ligament (PDL) have shown potential for periodontal regeneration. Although PDL-MSCs have been recognized as the best choic for cell-based periodontal regeneration, isolation of PDL-MSCs required tooth extraction which is impractical for clinical use. Supracrestal gingival connective tissue (SG) is a part of gingival tissue which located closely to PDL and can be harvested without tooth extraction. Here, the characteristics of MSCs derived from SG was evaluated. Differential gene expression profiles of hSG-MSCs, hPDL-MSCs, and human marginal gingival tissue (MG)-derived MSCs were compared. Results demonstrated that hSG-MSCs had a more similar gene expression profile to the hPDL-MSCs than the hMG-MSCs, suggested a potential candidate cell source of SG for future peridontal tissue engineering.

Genome-wide investigation of Pasteurella multocida identifies the stringent response as a negative regulator of hyaluronic acid capsule production

Project description:Pasteurella multocida is a Gram-negative capsulated bacterium responsible for a range of diseases that cause severe morbidity and mortality in livestock animals. The hyaluronic acid (HA) capsule produced by P. multocida serogroup A strains is a critical virulence factor. In this study, we utilised transposon-directed insertion site sequencing (TraDIS) to identify genes essential for in vitro growth of P. multocida, and combined TraDIS with discontinuous density gradients (TraDISort) to identify genes required for HA capsule production and regulation in this pathogen. Analysis of mutants with a high cell density phenotype, indicative of the loss of extracellular capsule, led to the identification of 69 genes important for capsule production. These genes included all previously characterized genes in the capsule biosynthesis locus, and fis and hfq that encode known positive regulators of P. multocida capsule. Many of the other capsule-associated genes identified in this study were involved in regulation or activation of the stringent response, including spoT and relA that encode proteins that regulate the concentration of guanosine alarmones. Disruption of the autoregulatory domains in the C-terminal half of SpoT using insertional mutagenesis resulted in reduced expression of capsule biosynthesis genes and an acapsular phenotype. Overall, these findings have greatly increased the understanding of hyaluronic acid capsule production and regulation in P. multocida.

Hyaluronic acid synthesis is required for zebrafish tail fin regeneration

Project description:Using genome-wide transcriptional profiling and whole-mount expression analyses of zebrafish larvae, we have identified hyaluronan synthase 3 (has3) as an upregulated gene during caudal fin regeneration. has3 expression is induced in the wound epithelium within hours after tail amputation, and its onset and maintenance requires fibroblast growth factor, phosphoinositide 3-kinase, and transforming growth factor-β signaling. Inhibition of hyaluronic acid (HA) synthesis by the small molecule 4-methylumbelliferone (4-MU) impaired tail regeneration in zebrafish larvae by preventing injury-induced cell proliferation. In addition, 4-MU reduced the expression of genes associated with wound epithelium and blastema function. Treatment with the glycogen synthase 3-kinase inhibitors rescued 4-MU-induced defects in cell proliferation and tail regeneration, even though only a subset of wound epithelium and blastema markers was restored. Our findings uncover a role for HA biosynthesis in zebrafish tail regeneration and its epistatic relationships with other regenerative processes.
