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.
