ABSTRACT: In the present investigation, an experimental model of endothelial cell injury was established by subjecting RRAECs to Ang II (5×10-7mol/L) for a duration of 24 h. Subsequently, this model was treated with a combination of Calycosin (3mg/L) and Tanshinone II (3mg/L). The changes in total ATP levels and autophagy function in RRAECs were evaluated using the ATP assay and dansylcadaverine (MDC) staining, respectively. Annexin V-FITC/PI staining and transwell assay were utilized to quantify the apoptosis rate and migration function of RRAECs. Moreover, the utilization of RNA-sequencing technology facilitated the identification of differentially expressed (DE) lncRNAs and mRNAs between various groups. Subsequently, a coexpression network between DE lncRNAs and mRNAs was constructed, followed by the implementation of GO and KEGG pathway enrichment analyses to elucidate the functional implications of the DE mRNAs interacting with lncRNAs within this network.
Project description:In this study, RNA-sequencing technology was employed to identify the differentially expressed lncRNAs (DE-lncRNAs) and mRNAs (DE-mRNAs) between H1975 and H1975OR. Based on the starbase 2.0 database, the potential targeting relationships between DE-lncRNAs and DE-mRNAs were predicted and identified to construct the ceRNA networks. Subsequently, functional and pathway enrichment analysis were carried for target DE-mRNAs to obtain functional pathways associated with Osimertinib resistance and potential drug resistance-related DE-mRNAs. Besides, the expression of LINC00313 and COL1A1 was validated by q-Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR). Finally, the activation of PI3K/Akt pathway was proved by immunohistochemistry staining.
Project description:Phenotypically, we observed that both genistein and Tanshinone I exert the inhibitory effects on the proliferation and metastasis of cervical cancer. The aim of this study was to comprehensively decipher the anti-metastasis effect and molecular mechanism of genistein and Tanshinone I on the cervical cancer. The results showed that genistein and Tanshinone I strongly change the RNA profiling of the cervical cancer cells in different manners: genistein mainly targets on regulation of RNA transcription, central carbon metabolism in cancer, microRNAs in cancer and focal adhesion etc; Tanshinone I mainly effects on central carbon metabolism in cancer, mitophagy process.
Project description:Tanshinones are the major bioactive compounds of Salvia miltiorrhiza Bunge (Danshen), roots, which are used in many therapeutic remedies in Chinese traditional medicine. We investigated the anticancer effects of tanshinones on the highly invasive human lung adenocarcinoma cell line, CL1-5. Tanshinone I significantly inhibited migration, invasion, and gelatinase activity in macrophage-conditioned medium (CM)-stimulated CL1-5 cells in vitro and also reduced the tumorigenesis and metastasis in CL1-5-bearing severe combined immunodeficiency mice. Unlike tanshinone IIA, which induces cell apoptosis, tanshinone I had no significant cytotoxicity. Real-time quantitative polymerase chain reaction (RTQ-PCR), luciferase reporter assay, and an electrophoretic mobility shift assay revealed that tanshinone I reduces the transcriptional activity of interleukin-8 (IL-8), the angiogenic factor involved in cancer metastasis, by attenuating the DNA-binding activity of activator protein-1 and nuclear factor kappaB in CM-stimulated CL1-5 cells. Microarray and pathway analysis of tumor-related genes identified the differentially expressed genes responding to tanshinone I, and these results were validated by RTQ-PCR. The responsive genes included human platelet-derived growth factor beta chain, Shb, H-ras, N-Ras, mitogen-activated protein kinase kinase 3, phosphoinositide-3-kinase, CD44, Rac1, and collagen type IV; these genes may be associated with the Ras MAPK and Rac1 signaling pathways. These results suggest that tanshinone I exhibits anticancer effects both in vitro and in vivo, and that these effects are mediated at least partly through the IL-8, Ras MAPK, and Rac1 signaling pathways.

Project description:Tanshinone IIA (Tan IIA) is a diterpene quinone extracted from the root of Salvia miltiorrhiza, a Chinese traditional herb. Although previous studies have reported the anti-tumor effects of Tan IIA on various human cancer cells, the underlying mechanisms are not clear. We used microarrays to detail the global programme of gene expression underlying Tan IIA's apoptotic effects on leukemia cells and identified significantly differentially expressed genes (SDEGs).

We used microarrays to detail the global programme of gene expression underlying Tan IIA's apoptotic effects on leukemia cells and identified significantly differentially expressed genes (SDEGs). Five human leukemia cell lines were selected for RNA extraction and hybridization on Affymetrix microarrays.To identify genes that are related to Tan IIA sensitivities, we carried out expression profiling on five cell lines.The sample named HL60, MEG01, MOLT,THP1 and U937_control were treated with DMSO. U937 cell line was selected with Tan IIA treatment for 12 h and 24 h, respectively.
Project description:We report the expression of mRNA and lncRNA in mouse uterus between periods of embryo implantation and labor by high-throughput seq. By the seq analysis of mRNA and lncRNA expression, 1971 differentially expressed (DE) mRNAs and 1543 DE lncRNAs were found between E0.5 and E4.5 at the embryo implantation stage, while 1149 DE mRNAs and 410 DE lncRNAs were found between E15.5 and E18.5 at the labor stage. While 117 DE mRNAs and 19 DE lncRNAs were commonly expressed between the two stages. This study provides a basic gene expression of altered pregnancy status.
Project description:Pseudorabies, an acute infectious disease caused by pseudorabies virus (PRV), has caused enormous economic losses to the breeding industry in many countries worldwide. Accumulating evidence indicates that long non-coding RNAs (lncRNAs) may play important roles in the antiviral responses. However, little is known about the identification and functions of swine lncRNAs in cellular antiviral responses against PRV II. In this study, we detected the expression profiles of host lncRNAs and mRNAs from PRV-DX, a wild-type (WT) strain of PRV II, and its attenuated gE-TK- PRV-DX infected cells by high-throughput RNA sequencing. Finally, we identified differentially expressed (DE) 664 lncRNAs and DE 7,199 mRNAs from PRV-DX infected cells, and 654 DE lncRNAs and DE 7,149 mRNAs from gE-TK- PRV-DX infected cells when compared to MOCK infected cells, respectively, especially including 469 common DE lncRNAs and 5836 DE mRNAs. Besides 276 DE lncRNAs and 2,272 DE mRNAs between PRV-DX and gE-TK- PRV-DX infected cells were identified. The potential functions of the significant DE lncRNAs were involved in interleukin secretion, axon extension and metabolic process based on the Gene ontology and Kyoto Encyclopedia of Genes and Genomes databases. Taken together, results highlighted the potentials of lncRNA as targets for antiviral therapy and enriched the current knowledge of the mechanisms underlying the interaction between PRV II and its host cells.
Project description:We investigated comprehensive transcriptomic change in rat aorta tolerant to nitroglycerin (GTN) with a focus on lncRNAs. We employed RNA sequencing (RNA-seq) technique and identified 22788 genes (RPKM > 0.1, 14720 protein coding and 4408 lncRNA). And 115 differentially expressed (DE) mRNAs (65 upregulated and 50 downregulated) and 104 DE lncRNAs (56 upregulated and 48 downregulated) were found in GTN-tolerant aortas. Many DE mRNAs and cis-target genes of DE lncRNAs have been implicated in regulation of blood pressure or cell contraction. Collectively, these results suggested that dysregulated mRNAs and lncRNAs contribute to the development of GTN tolerance and might be used as novel potential targets to prevent and reverse GTN tolerance.
Project description:this study was designed to acquire mRNA and long non-coding RNA (lncRNA) profiles of 2-cells, 4-cells and blastocysts derived from vitrified porcine cloned zygotes using transcriptome sequencing. We identified 167 differentially expressed (DE) mRNAs and 516 DE lncRNAs in 2-cell stage, 469 DE mRNAs and 565 lncRNAs in 4-cell stage, and 389 DE mRNAs and 816 DE lncRNAs in blastocyst stage. Functional enrichment analysis revealed that DE mRNAs during embryo development were involved in many regulatory mechanisms related to cell cycle, cell proliferation, apoptosis, metabolism and others. Moreover, the target genes of DE lncRNAs in the three embryonic stages were also enriched in many key GO terms or pathways such as ‘defense response’, ‘linoleic acid metabolic process’, ‘embryonic axis specification’, ‘negative regulation of protein neddylation’, etc. In conclusion, the present study provided comprehensive transcriptomic data about mRNA and lncRNA for the vitrified porcine cloned zygotes during different developmental stages, which contributed to further understand the potential cryodamage mechanisms responsible for impaired embryo development.
