Human gingival fibroblasts: control vs. lysophosphatidic acid (LPA 18:1)-treated

ABSTRACT: Transcriptional profiling of pass 2 primary human gingival fibroblasts (GF) comparing control untreated GF with GF treated with LPA 18:1 for 2h or 8h. The goal of this study was to determine the effects of LPA 18:1 on global GF gene expression.

Gene expression analysis of gingival fibromatosis gingiva

Project description:Gingival fibromatosis (GF) is a rare oral condition characterized by proliferative fibrous overgrowth of both the attached and marginal gingiva, and the interdental papilla. But there were no papers about gene expression of gingival fibromatosis. The aim of this study was to identify the differential expression of genes in GF using cDNA microarray analysis.

Influence of lysophosphatidic acid (LPA) and LPA together with interferon tau (IFNt) on transcriptional profiling of bovine endometrial cells.

Project description:The endometrium plays a crucial role in the reproductive organs in the aspect of embryo-maternal communication and pregnancy. This study investigated transcriptome profiles of endometrial cells stimulated with PBS, LPA and LPA in combination with IFNt. LPA, one of the signaling molecule, is locally produced and released from the bovine endometrium during estrous cycle and early pregnancy. The highest concentration of LPA and expression of its active receptor (LPAR1) were detected in bovine endometrium at the time of maternal recognition of pregnancy, when the conceptus announces its presence by increased IFNt production. Using transcriptomic approach we compared the influence of LPA and LPA together with IFNt on the gene expression profiles in bovine endometrial cells. A total of nine normally cycling Holstein/Polish Black and White (75/25% respectively) cows were used in this study. Global transcriptional profiling was performed using co-cultured stromal and epithelial cells (ratio - 3:1) isolated from bovine endometrium. Three experimental conditions (control (PBS), LPA and LPA plus IFNt) with three replicates per condition were prepared. Total RNAs were extracted from 9 pooled samples (n=3 for each sample) amplified and hybridized onto Affymetrix microarrays.

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.

Transcriptomic analysis of human breast and prostate cancer cell lines on lysophosphatidic acid (LPA) stimulation

Project description:LPA is a natural bioactive lipid with growth factor-like functions due to activation of series of six G protein-coupled receptors (LPA1-6). In this study we determine the LPA induced early-gene expression profile in three unrelated human cancer cell lines (MDA-MB-231, MCF7, PC3) with an objective to identify potential biomarker/s specifically upregulated through the activation of LPA receptor type 1 (LPA1) MDA-MB-231, MCF7, PC3 cells were serum starved for 24h and then stimulated with LPA (1ÂµM) for 45min. The controls were the serum starved unstimulated cells. Two replicates for each sample were included in this study. Microarray analysis was performed using a high-density oligonucleotide array (GeneChip Human Genome U133 plus 2.0 array, Affymetrix)

Gene-expression analysis of human embryonic stem cell (HESC-)- derived rosette-forming neural progenitor cells (NPCs) in the presence of lysophosphatidic acid (LPA)

Project description:As part of our study on the effect of LPA on HESC-derived NPCs, we have employed whole genome microarray analysis to identify genes which were up- and downregulated in the presence of LPA compared to non-LPA-treated control-NPCs and which might be involved in the expansion of the apical domain of NPCs and large rosette formation that we observe after LPA-treatment.
