Project description:Backgroud: Botulinum toxin type A (BTXA) is widely used for the treatment of sialorrhea and other glandular hypersecretion diseases. Micro ribonucleic acid (miRNA) plays an important role in the occurrence and development of salivary diseases, but it is still unclear which role miRNA plays during the inhibition of salivary secretion triggered by BTXA. This work was aimed to explore the miRNA-mRNA expression profiles and functional network after injection of BTXA into submandibular gland. Methods: The differentially expressed (DE) miRNAs and mRNAs between the control group and BTXA group were identified through high-throughput sequencing and bioinformatic analyses and were confirmed by qRT-PCR. Bioinformatic analyses were performed to identify the critical biological functions and signalling pathways and established the functional network. Results: A total of 19 DE miRNAs and 1072 DE mRNAs were identified between the control group and BTXA group. We confirmed 6 DE miRNAs through the qRT-PCR validation. Bioinformatic analysis identified that several pathways may be associated with the inhibition of salivary secretion, such as MAPK signaling pathway, Tight junction and Cytokine-cytokine receptor interaction. We predicted the target genes of these 6 DE miRNAs and established the miRNA-mRNA interaction network. The intersection of DE mRNAs and target genes was performed and finally obtained 7 mRNAs: EGR2, PAQR9, ZKSCAN1, USP6N, lCYB561A3, ZFHX4 and CLIC5. Conclusions: Our study describes the miRNA and mRNA expression profiles and functional network after injection of BTXA into submandibular gland. These findings explore the mechanism of BTXA in inhibiting salivary secretion, and probably provide a new idea for the clinical application. Key words: miRNA-mRNA, BTXA, submandibular gland

Project description:BackgroundHyposalivation is one of the common symptoms of diabetes. Although long non-coding RNAs (lncRNAs) have recently been reported to play important roles in the pathogenesis of diabetes, the role of lncRNAs in diabetes-induced hyposalivation remains unknown.MethodsThe present study aimed to explore the function of lncRNA-microRNA-mRNA regulatory network in the submandibular gland (SMGs) under the context of diabetes. LncRNA expression profile of the SMGs was analyzed using microarray technology. Differentially expressed lncRNAs were confirmed using real-time quantitative PCR. Bioinformatics analyses were performed, and Coding-non-coding gene co-expression (CNC) and competing endogenous RNA (ceRNA) networks were constructed to explore the potential mechanisms of diabetes-induced hyposalivation.ResultsA total of 1273 differentially expressed lncRNAs (536 up-regulated and 737 downregulated) were identified in the SMGs tissues of db/db mice. CNC and ceRNA network analyses were performed based on five differentially expressed lncRNAs validated by real-time quantitative PCR. Gene Ontology analysis of target genes of CNC network revealed that "calcium ion binding" was a highly enriched molecular function. Kyoto Encyclopedia of Genes and Genomes pathway analysis of target genes of ceRNA network revealed that the "mammalian target of rapamycin signaling pathway" was significantly enriched.ConclusionsOn the whole, the findings of the present study may provide insight into the possible mechanism of diabetes-induced hyposalivation.

Project description:Abstract: Backgroud: This study was to explore long noncoding RNA (lncRNA) and messenger RNA (mRNA) expression profiles and construct functional networks to analyze their biological functions when botulinum toxin type A (BTXA) inhibited salivary secretion. Methods: BTXA and saline were injected into the submandibular gland of rats as the BTXA group and control group, respectively. Morphological and secretory function tests validated the animal models. Microarray analysis was applied to identify the expression variation of lncRNA and mRNA and were confirmed by qRT-PCR. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed to explicit the biological functions. The construction of functional networks including lncRNA-mRNA co-expression network and competing endogenous RNA (ceRNA) network was to reveal the interaction between coding and noncoding genes. Results: A total of 254 lncRNAs and 631 mRNAs were differentially expressed (DE) between the control group and the BTXA group. Ten lncRNAs and eleven mRNAs were confirmed by qRT-PCR and the results were consistent with the microarray analysis. The bioinformatic analysis found that most of mRNAs were closely related to transmembrane transporter activity. LncRNA-mRNA co-expression network and ceRNA network were constructed and identified several critical mRNA-lncRNA axes and key microRNAs related to salivary secretion, respectively. Conclusions: Our study identified DE lncRNAs and mRNAs through microarray analysis and explored the biological functions and interaction between coding and noncoding genes through bioinformatics analysis. These findings may provide new directions for the mechanism of BTXA to inhibit salivary secretion.

Project description:Hyposalivation is a complication of hypertension. However, little is known about the role of long non-coding RNAs (lncRNAs) in salivary glands in hypertension. This study aimed to compare the lncRNA and mRNA expression profiles between spontaneous hypertension rats (SHRs) and Wistar-Kyoto (WKY) rats through microarray analysis and apple bioinformatics methods to analyse their potential roles in hyposalivation. The differentially expressed (DE) lncRNAs and mRNAs were confirmed by quantitative real-time PCR (qRT-PCR). Compared with WKY rats, 225 DE lncRNAs and 473 DE mRNAs were identified in the SMG of SHRs. The pathway analyses of DE mRNAs showed that inflammatory mediator regulation of transient receptor potential channels was involved in hyposalivation in SHRs. Ten DE lncRNAs were chosen for further research. A coding-non-coding gene co-expression (CNC) network and competing endogenous RNA (ceRNA) network analysis revealed that the potential functions of these 10 DE lncRNAs were closely connected with the processes of the immune response. This study showed abundant DE lncRNAs and mRNAs in hypertensive SMGs. Furthermore, our results indicated strong associations between the immune response and hyposalivation and showed the potential of immune-related genes as novel and therapeutic targets for hyposalivation.
