Comprehensive analysis of differentially expressed lncRNA, and mRNA and their ceRNA networks in mice with the initial stage acute pancreatitis

ABSTRACT: Acute pancreatitis (AP) is a prevalent digestive disorder with significant morbidity and mortality rates. This study, for the first time, employed high-throughput sequencing on pancreatic tissues from normal and AP mice to identify differentially expressed long noncoding RNAs (lncRNAs) and mRNAs, as well as related signaling pathways, in the early stage of AP. We found 261 lncRNAs and 1,522 mRNAs to be differentially expressed, with Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses revealing gene functions enriched in cellular metabolism, intercellular structure, and positive regulation of inflammation. By constructing lncRNA-miRNA-mRNA networks, we explored underlying mechanisms and interactions in AP. Notably, knockout of Neat1 in mice inhibited pyroptosis in AP and severe acute pancreatitis (SAP) models, suggesting Neat1's pivotal role in AP pathogenesis. These findings highlight the importance of lncRNAs, particularly Neat1, in AP, offering new insights into SAP pathogenesis and potential therapeutic targets.

Hepatic transcriptome analysis of control, acute pancreatitis and severe acute pancreatitis mice

Project description:Purpose: The purpose of this study was to compare the hepatic transcriptome in the control group, acute pancreatitis, and severe acute pancreatitis, in order to identify metabolic gene changes during pancreatitis. Methods: 6-week Balb/c mice were subjected to AP (caerulein), SAP (caerulein and LPS) and control (saline), and mice liver tissues were harvested at 24 hours for RNA preparation (n=8 each group). Results: Among 11952 mapped genes, 8977 differentially expressed genes were identified by RNA-seq, including 351 genes induced in AP compare to Control and 5249 genes down regulated in SAP compare to AP. The genes up regulated were mainly related to fatty acid oxidation and ketone body synthesis especially Cpt2 and Acadvl, while genes that down regulated were associated with energy metabolism and inflammation. The overlap of two gene sets were 96 genes that involved in fatty acid metabolism. Conclusions: Our study revealed that in AP, genes associated with ketone body synthesis are upregulated in liver, in SAP, fatty acid oxidation related genes are downregulated in liver. Our data revealed the crosstalk between pancreas and liver, illustrated the difference of metabolism in AP and SAP.

Effect of emodin on long non-coding RNA-mRNA networks in rats with severe acute pancreatitis-induced acute lung injury

Project description:Long non-coding RNAs (lncRNAs) reportedly contribute to disease pathogenesis and drug treatment effects. Both emodin and dexamethasone (DEX) have been used for the treatment of severe acute pancreatitis-associated acute lung injury (SAP-ALI). However, lncRNA regulation networks related to SAP-ALI pathogenesis and drug treatment are unreported. In this study, lncRNAs and mRNAs in the lung tissue of SAP-ALI and control rats, with or without drug treatment (emodin or DEX), were assessed by RNA sequencing. Results showed that both emodin and DEX were therapeutic for SAP-ALI and that mRNA and lncRNA levels differed between untreated and treated SAP-ALI rats. Gene expression profile relationships for emodin treated and control rats were higher than DEX treated and untreated animals. By comparison of control and SAP-ALI animals, more upregulated than downregulated mRNAs and lncRNAs were observed with emodin treatment. For DEX treatment, more downregulated than upregulated mRNAs and lncRNAs were observed. Functional analysis demonstrated both upregulated mRNA and co-expressed genes with upregulated lncRNAs were enriched in inflammatory and immune response pathways. Further, emodin associated lncRNAs and mRNAs co-expressed modules were different from those associated with DEX. Quantitative polymerase chain reaction demonstrates that selected lncRNA and mRNA co-expressed modules were different in the lung tissue of emodin and DEX treated rats. Also, emodin had different effects compared to DEX on the co-expression network of lncRNAs Rn60_7_1164.1 and AABR07062477.2 for the blue lncRNA module and Nrp1 for the green mRNA module. In conclusion, this study provides evidence that emodin may be a suitable alternative or complementary medicine for treatment of SAP-ALI.

Comprehensive analysis of differentially expressed lncRNA, circRNA and mRNA and their ceRNA networks in mice with severe acute pancreatitis

Project description:Severe acute pancreatitis (SAP) is an acute digestive system disease with high morbidity mortality and hospitalization rate worldwide, due to various causes and unknown pathogenesis. In recent years, a large number of studies have confirmed that non-coding RNAs (ncRNAs) play an important role in many cellular processes and disease occurrence. However, the underlying mechanisms based on the function of ncRNAs, including long noncoding RNA (lncRNA) and circular RNA (circRNA), in SAP remain unclear. In this study, we performed high-throughput sequencing on the pancreatic tissues of 3 normal mice and 3 SAP mice for the first time to describe and analyze the expression profiles of ncRNAs, including lncRNA and circRNA. Our results identified that 49 lncRNAs, 56 circRNAs and 1194 mRNAs were differentially expressed in the SAP group, compared with the control group. Furthermore, we performed Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of differentially expressed lncRNAs and circRNAs, and found that the functions of the parental genes are enriched in the calcium-regulated signaling pathway, NF-κB signaling pathway, autophagy and protein digestion and absorption processes, which are closely related to the central events in pathogenesis of SAP. We also constructed lncRNA/circRNA-miRNA-mRNA networks to further explore their underlying mechanism and possible relationships in SAP. We found that in the competitive endogenous RNA (ceRNA) networks, differentially expressed lncRNAs and circRNAs are mainly involved in the apoptosis pathway and calcium signal transduction pathway. In conclusion, we found that lncRNAs and circRNAs play an important role in the pathogenesis of SAP, which may provide new insights in further exploring the pathogenesis of SAP and seek new targets for SAP.

Genome-wide map of m6A circRNAs identified in mice model of severe acute pancreatitis

Project description:Severe acute pancreatitis (SAP) is the most serious type of pancreatitis with high morbidity and mortality. The underlying pathophysiological mechanism of SAP is complicated and lacking in effective therapeutic options in clinic. In recent years, circular RNAs (circRNAs) are found to be N6-methyladenosine (m6A)-modified and m6A modification of circRNAs plays important roles in physiological and pathological processes. However, the role of m6A modification of circRNAs in SAP remains unknown. Here, we aim to identify differentially expressed m6A circRNAs in SAP and to determine their biological significance and potential mechanisms in SAP. Firstly, we identified 903 m6A peaks that distribute on 781 circRNAs in SAP and control groups. Among them, 57 circRNAs with differentially expressed m6A peaks were identified, of which 32 were upregulated and 25 were downregulated. The total m6A level of circRNAs was reduced compared with control group. Moreover, the function analysis of these m6A circRNAs in SAP found that some important pathways involved in the pathogenesis of SAP, such as protein digestion and regulation of autophagy. In m6A circRNA-microRNA networks, several important miRNAs involved in the occurrence and development of SAP were found to bind to these m6A circRNAs potentially, such as miR-24-3p, miR-26a, miR-92b, miR-216b, miR-324-5p and miR-762. Notably, ALKBH5 was found to be upregulated in SAP. In conclusion, these results demonstrated that m6A modification of circRNAs was widely existed and may play important roles in the pathogenesis of SAP. Our findings provide novel insights regarding understanding the pathophysiological mechanism of SAP and seeking new therapeutic targets for SAP.
