Genome-wide analysis of long noncoding RNA and messager RNA expression in ApoE-deficient mice

ABSTRACT: Atherosclerosis is a multifactorial chronic inflammatory disease with high prevalence and has become the first reason for death worldwide. Long non-coding RNAs (lncRNAs) are non-coding RNAs with a length of >200 bp. LncRNAs participate in many biological and pathological processes such as carcinogenesis, cardiovascular diseases. The present study was designed to investigate the lncRNA and mRNA expression in the aorta of diet-induced ApoE(-/-) mice using microarray analysis. The homozygous male apoE(-/-) mice were randomly divided into two groups, with 3 animals for each group. The normal diet group was fed with normal chow, while the treated group was fed with a high-fat, high-cholesterol diet containing 20% fat and 2.5% cholesterol. The treatment duration is 8-week. After treatment, the aorta of each mouse was taken, and the lncRNA and mRNAs profiles were detected using Agilent mouse lncRNA Microarray (4*180K, Design ID: 049801) which contains 51302 lncRNAs and 39430 mRNAs. As a result, a total of 354 differentially expressed lncRNAs, including 168 up-regulated and 186 down-regulated, were identified (≥2.0 folds). Simultaneously, we also identified 357 differentially expressed protein coding mRNAs from the same chip, including 211 up-regulated 146 down-regulated mRNAs. The present study identified a panel of dysregulated lncRNAs and mRNAs that may be potential biomarkers or drug targets and correlated with the pathogenesis of atherosclerosis.

Expression data from mouse aorta with chronic intermittent hypoxia exposure

Project description:Atherosclerosis is the pathological basis of cardiovascular disease. Obstructive sleep apnea aggravates atherosclerosis, and chronic intermittent hypoxia (CIH) as a prominent feature of obstructive sleep apnea plays an important role during the process of atherosclerosis. The mechanisms of CIH in the development of atherosclerosis remain unclear. The microarray was used to investigate differentially expressed mRNAs and long noncoding RNAs (lncRNAs) in aorta from five groups of ApoE-/- mice fed with a high-fat diet and exposed to various conditions: normoxia for 8 weeks, CIH for 8 weeks, normoxia for 12 weeks, CIH for 12 weeks, or CIH for 8 weeks followed by normoxia for 4 weeks.

Genome-wide analysis of differentially expressed profiles of mRNAs, lncRNAs and circRNAs in aorta samples of F. nucleatum-infected mice

Project description:Periodontitis is an independent risk factor for atherosclerosis, and F. nucleatum is one of the periodontal pathogens. Several studies have confirmed that non-coding RNAs could affect all aspects of AS disease progression, including lipid metabolism, foam cell formation, cell necrosis, etc. However, no studies have explored whether F. nucleatum could affect AS disease progression by regulating non-coding RNAs. In this study, we intend to acquire mRNAs, lncRNAs and circRNAs expression profiles of aorta samples of AS mice from the F. nucleatum group and the Control group by next-generation sequencing(NGS) and perform bioinformatics analysis. Results revealed that 465 mRNA expression were up-regulated and 382 mRNA expression were down-regulated significantly. Some lncRNAs and circRNAs could suppress the binding of miRNA with target genes in post-transcriptional regulation. By integrating with DE-miRNAs-DEGs pairs and screening the common miRNAs, and mRNAs, lncRNAs, circRNAs that have targeted and negatively correlated relationship with the common miRNAs, lncRNA-miRNA-mRNA (including 34 DE-miRNAs, 42 DE-lncRNAs, and 111 DE-mRNAs) and circRNA-miRNA-mRNA (including 19 DE-miRNAs, 49 DE-circRNAs, and 87 DE-mRNAs) regulatory co-expression networks were constructed. GO enrichment analysis was performed on the differentially expressed mRNAs, which were found to be related to molecular functions, biological processes and cellular components such as protein binding, nucleus, postsynaptic dense zone, protein phosphorylation. KEGG analysis showed that they were related to ErbB signaling pathway, neurotrophic factor signaling pathway, glucagon signaling pathway and apoptosis signaling pathway. This suggested that F. nucleatum could promote the development of atherosclerosis through non-coding RNAs network regulation.

Transcription profiling of mouse C57BL/6 C3H/HeJ apoE-/- knockout aorta

Project description:Inbred mouse strains C57BL/6J (B6) and C3H/HeJ (C3H) exhibit a marked difference in their susceptibility to atherosclerosis and the arterial wall has proven to be a source of the difference in atherosclerosis susceptibility. Genome-wide gene expression analysis was conducted in aortic walls of the two strains. Total RNA was extracted from aortas of 6-week-old female B6 and C3H apoE-deficient (apoE-/-) mice fed a chow or Western diet. 1514 genes in chow fed mice and 590 genes in Western fed mice were found to be differentially expressed between the two strains. RNA was extracted from aorta using a Trizol protocol. Total RNA was pooled in an equal amount from 4 mice for each group. Standard Affymetrix procedures were performed using 8ug of total RNA. Microarrays were used to detect gene expression in aortic walls of two apoE-deficient mouse strains when fed a chow or western diet. Experiment Overall Design: 4 groups of mice were studied: C57BL/6 apoE-/- mice on chow diet (03-62_BC), C57BL/6 apoE-/- mice on Western diet (03-62_BW), C3H/HeJ apoE-/- mice on chow diet (03-62_CC), and C3H/HeJ apoE-/- mice on Western diet (03-62_CW). Mice were weaned at 3 weeks of age onto a chow diet. At 4 weeks of age, mice were switched onto a western diet or continued the chow diet for 2 additional weeks.

Genome-wide profiling of long noncoding RNA expression patterns in chemoresistant breast cancer cells

Project description:Long non-coding RNAs (lncRNAs) are involved in cancer progression. In this study, the lncRNA profiling were analyzed in chemoresistant and sensitive breast cancer cells. We found a group of dysregulated lncRNAs in chemoresistant cells. Expression of dysregulated lncRNAs are correlated with dysregulated mRNAs, and enriched in GO and KEGG pathways related with cancer progression and chemoresistance development. Within those lncRNA-mRNA interactions, some lncRNAs may cis-regulate neighboring protein coding genes and involved in chemoresistance. The lncRNA NONHSAT028712 was then validated to regulate nearby CDK2 and interfere with cell cycle and chemoresistance. Furthermore, we identified another group of lncRNAs trans-regulated gene expression via interacting with different transcription factors (TF). Whereby NONHSAT057282 and NONHSAG023333 was found to modulate chemoresistance and most likely interacted with ELF1 and E2F1 respectively. In conclusion, this study reported for the first time the lncRNA expression patterns in chemoresistant breast cancer cells, and provided a group of novel lncRNA targets in mediating chemoresistance development in both cis- and trans- action mode. MCF-7/ADM replication 3 times, MCF-7/WT replication 3 times

Transcription profiling of mouse aorta genes of APOE-deficient animals receiving the ACE inhibitor captopril

Project description:Microarray gene expression profiling of aorta genes of APOE-deficient mice receiving atherosclerosis treatment with the ACE inhibitor captopril. Hypercholesterolemic APOE-deficient mice were used as a standard model of atherosclerosis to study gene expression changes during atherosclerosis treatment with the ACE inhibitor captopril. Microarray analysis was performed of whole aortas isolated from captopril-treated APOE-deficient mice relative to untreated APOE-deficient mice with overt atherosclerosis, and nontransgenic control mice. Microarray gene expression profiling revealed that captopril-mediated atherosclerosis prevention involved inhibition of aorta-infiltrating immune cells such as pro-atherogenic T lymphocytes and macrophages. Experiment Overall Design: Microarray gene expression profiling was performed of whole aortas isolated from APOE-deficient mice with atherosclerosis relative to captopril-treated APOE-deficient mice, and nontransgenic control mice. Three study groups were analyzed, i.e. 8-months-old untreated APOE-deficient mice with overt atherosclerosis, age-matched APOE-deficient mice treated for 7 months with the angiotensin-converting enzyme (ACE) inhibitor, captopril (20 mg/kg in drinking water), and nontransgenic control C57BL/6J mice. Two biological replicates were made of each group, and total RNA of three aortas was pooled for one gene chip.

Integrated analysis of lncRNA and mRNA expression profiles in the submandibular glands of DIO mice

Project description:Objective: Obesity contributes to the dysfunction of salivary gland. To explore the specific underlying mechanism for obesity-induced hyposalivation, a model for high-fat diet-induced obese (DIO) mice were constructed to analyze long non-coding RNAs (lncRNAs) and messenger RNAs (mRNAs) expression profiles. Methods: The DIO group and control group were fed a diet containing 60 kcal% fat and a normal chow diet for 16 weeks respectively. Microarray analyses were performed to detect the expression profiles of lncRNA and mRNA in submandibular gland tissues from control group mice and DIO mice. Gene ontology, kyoto encyclopedia of genes and genomes, protein-protein interaction, coding-non-coding gene co-expression, transcription factors and competing endogenous RNA analyses were performed to examine the function of differential expressed genes. Results: The microarray identified that 624 lncRNAs, along with 297 mRNAs were differentially expressed. Bioinformatic analyses revealed that “complement and coagulation cascades”, “glutathione metabolism”, “cysteine and methionine metabolism”, and “estrogen signaling pathway” were significantly associated with candidate lncRNAs, transcription factors analysis on candidate lncRNAs reveled several genes such as tribbles pseudokinase 3 may play regulatory roles. Conclusions: Our results revealed the expression profiles of lncRNAs and mRNAs and provided new insights into the mechanism of obesity-induced hyposalivation using bioinformatic analyses.
