Project description:Purpose: The goals of this study are to compare NGS-derived gingiva transcriptome profiling (RNA-seq) of rats with or without experimental periodontitis and to explore the effect of curcumin/ZNPs hydrogel on the transcription of gingiva in rats with periodontitis. Methods: Six-week-old male Sprague-Dawley rats weighing 250–300 g (Dashuo company, China) were randomly divided into five groups (n = 5 per group): i) healthy control (Sham); ii) experimental periodontitis (EP); iii) experimental periodontitis treated by curcumin hydrogel (EP+Cur); iv) experimental periodontitis treated by ZNPs hydrogel (EP+ZNPs); v) experimental periodontitis treated by curcumin/ZNPs hydrogel (EP+Cur/ZNPs). Animals were anesthetized with isoflurane (5% induction, 2% maintenance, sealed until euthanized) and intramuscularly administered 0.1 mL penicillin (40,000 U/mL) for 7 days. EP was established by ligature with 4–0 silk thread around the bilateral maxillary first molars. Three days after ligature, P. gingivalis ATCC 33277 (107 CFU/mL) was smeared onto silk twice. Rats in the EP+Cur group were treated by curcumin hydrogel (Dalian Meilun Biotech Co., Ltd), EP+ZNPs group were treated by ZNPs hydrogel (Shanghai aladdin Biochemical Technology Co., Ltd), and EP+Cur/ZNPs group were treated by curcumin/ZNPs hydrogel. Total RNA was extracted with TRIzol® reagent (Thermo Fisher Scientific, Inc.). The TruSeq Stranded total RNA with RiboZero Plus kit (IIlumina, San Diego, CA) was used to obtain a sequencing library from 1μg of total RNA. Eukaryotic mRNA sequencing was performed on Illumina Novaseq 6000 by Shanghai Majorbio Bio-pharm Technology Co., Ltd. Raw gene counts with a minimum of two counts per million in at least one sample were used for downstream analyses. Differentially expressed genes were determined by the DESeq2 Bioconductor/R package. qRT–PCR validation was performed using TaqMan and SYBR Green assays. Results: Transcriptome analysis of 25 samples was completed in this project, and a total of 184.45 Gb Clean Data was obtained. The Clean Data of each sample reached 5.92 Gb and above, and the Q30 base percentage was above 92.75%. The Clean Reads of each sample were compared with the designated reference genome, and the comparison rate ranged from 93.38% to 95.1%. A total of 26188 expressed genes were detected in this analysis, including 22736 known genes and 3452 new genes; 57,961 expressed transcripts, including 29332 known transcripts and 28629 new transcripts. Conclusions: Our study represents the first detailed analysis of gingival transcriptomes of rats treated by Cur/ZnO gel, with biologic replicates, generated by RNA-seq technology.

Project description:All experiment was done according to the Affymetrix manufacturerâs protocol. The resulting HGF gingiva expression profile(Hereditary gingival fibromatosis patient Gingiva replicate1 and replicate 2)was compared to normal gingiva control(Normal Gingiva replicate1 and replicate2). The data were collected and analyzed by GCOS 1.2 and GeneSpring 7.2 1-way T test. Experiment Overall Design: Hereditary gingival fibromatosis patient Gingiva (experimental) and Normal Gingiva (control) were used. N1 and P1 are gingiva tissue from female individuals while N2 and P2 are from male ones.

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.

Project description:The periodontium undergoes age-related cellular and clinical changes, but the involved genes are not yet known. Here, we investigated age-related genetic changes in gingiva at the transcriptomic level. Genes that were differentially expressed between young and old human gingiva were identified by RNA sequencing and verified by real-time PCR. A total of 1939 mRNA transcripts showed significantly differential expression between young and old gingival tissues. Matrix metalloprotease (MMP) regulation was the top pathway involved in gingival aging. MMP3, MMP9, MMP12, and MMP13 were upregulated in old gingival tissues, concomitantly with interleukin-1 beta (IL1B) expression. In vitro experiments using human gingival fibroblasts (hGFs) showed that MMP12 was upregulated in old hGFs compared to young hGFs. Moreover, the MMP3, MMP9 and IL1B levels were more highly stimulated by infection with the oral bacterium, Fusobacterium nucleatum, in old hGFs compared to young hGFs. Collectively, these findings suggest that, in gingiva, the upregulation of MMP12 may be a molecular hallmark of natural aging, while the upregulations of MMP3, MMM9, and IL1B may indicate externally (e.g., infection)-induced aging. These findings contribute to our understanding of the molecular targets involved in gingival aging.

Project description:An initial cellular change in the pathogenesis of heart failure is cardiomyocyte hypertrophy, characterized by increased cell size, enhanced protein synthesis and reactivation of fetal genes. In addition to mechanical stresses, several neurohumoral factors have been identified as potent hypertrophic agents, including angiotensin II, endothelin, and catecholamines. We used microarrays to study the gene expression during cardiac hypertrophy. Balb/c mice (6-8w) were treated with TAC, ATII infusion, and myocardial infarction. TAC model: The transverse aorta (TAC) was constricted at the upper left sternal border by ligation with a 7-silk surgical thread and 27-gauge needle, which was removed thereafter. Sham-operated controls underwent an identical procedure without TAC. At 1 week and 1month after the procedure, LV was harvested. Ang II model.: Ang II was dissolved in 0.9% NaCl at concentrations sufficient to allow an infusion rate of 2.0 mg/kg/day, known to produce hypertension and cardiac hypertrophy. Control mice received a vehicle (saline) via an osmotic minipump. At 1 week after the procedure, LV was harvested. MI model: The proximal portion of the left coronary artery was ligated using an 8-0 nylon thread. Myocardial ischemia was confirmed by the discoloration of the heart and typical ECG changes. After 30 min occlusion, the left coronary artery was reperfused by loosening the ligature. In sham-operated mice (SHAM), the pericardium was opened, but the coronary artery was not ligated. At 1 day, 1week, and 1 month after the procedure, LV was harvested.
