Pneumonectomized rats injected with the alkaloid toxin, monocrotaline, develop progressive neointimal pulmonary vascular obliteration and pulmonary hypertension resulting in right ventricular failure and death. The antiproliferative immunosuppressant, triptolide, attenuates neointimal formation and pulmonary hypertension in this disease model (Faul JL, Nishimura T, Berry GJ, Benson GV, Pearl RG, and Kao PN. Am J Respir Crit Care Med 162: 2252-2258, 2000). Pneumonectomized rats, injected with mon ...[more]

Expression data from treatment of actinomycin D and triptolide on MCF7 cells

Project description:Expression data from treatment of actinomycin D (2.5uM) and triptolide (500 nM) on MCF7 cells for 2, 4 and 6 hours. We used microarrays to explore the mechanism of triptolide action. MCF7 cells were treated with actinomycin D or triptolide for 2, 4 and 6 hours, RNA was extracted and hybridization on Affymetrix microarrays. Data were normalized by RMA.

Dysregulation of lncRNAs and circRNAs in mouse testes after exposure to triptolide

Project description:Triptolide has been shown to exert various pharmacological effects on systemic autoimmune diseases and cancers. However, its severe toxicity, especially reproduction toxicity, prevents wide clinical use for those people with fertility needs. Noncoding RNAs including lncRNAs and cicrRNAs are regulatory molecules that mediate a wide variety of physiological activities, which are critical for spermatogenesis, and their dysregulation might lead to male infertility. However, whether they are involved in triptolide-induced reproduction toxicity is fully unknown. Here, after exposure of mice to triptolide for 35 day, the total RNAs were used to investigate lncRNAs/cicrRNAs/mRNAs expression profiles by strand-specific RNA sequencing at the transcriptome level to help determine any RNA-related mechanisms in triptolide-induced toxicity. The results showed that triptolide significantly decreased the testicular weight, damaged testis and sperm morphology, reduced sperm motility and density. Furthermore, there's a remarkable deformity in sperm head and tail in triptolide-exposed mice. At the transcriptome level, the triptolide-treated mice exhibited aberrant expression profiles for lncRNAs/cicrRNAs/mRNAs, many of them were dysregulated. Gene ontology and pathway analyses revealed that the functions of differentially expressed lncRNA targets, cicrRNAs cognate genes and mRNAs were closely linked with many processes involved in spermatogenesis. Additionally, many newly identified lncRNAs /cicrRNAs displayed inducible expression, suggesting that they might be good candidate markers for triptolide-induced male reproductive toxicity. This study gives us an insight into understanding the reproductive system toxicity of triptolide and reminds us to strengthen the research on increasing efficacy and decreasing toxicity of triptolide.

The genes affected by Triptolide in activated mouse primary T cells

Project description:Triptolide possesses immunosuppressive activity and its efficacy is commonly believed to be related to the suppression of T cells. However, the underlying mechanism is still not well documented and most of the previous study adopted tumor cell lines of immune system as model cells in mechanism research, these cells’ signal transduction pathway can not reflect the real situation of immune system. In this study, we investigated the immunosuppressive mechanism of triptolide on T cell activation and proliferation using mouse primary T lymphocytes. These effects were analyzed along with activation of the TCR and AP-1 pathway. We used microarrays to detail the global programme of gene expression underlying stimulation and triptolide treatment. Mouse primary T cells stimulated with anti-CD3/CD28 antibodies treated with triptolide or not treated with triptolide were selected for RNA extraction and hybridization on Affymetrix microarrays.

Different osteogenic differentiation behavior of canine mesenchymal stem cells derived from bone marrow and dental pulp: the proteomics profile

Project description:Although various sources of cMSCs show similar characteristics, they are different in osteogenic potential due to their original cellular sources. Thus, this study was designed to globally explore and analyze the in vitro differentiation potential and behavior of canine bone-marrow derived mesenchymal stem cells (cBM-MSCs) and canine dental pulp stem cells (cDPSCs) toward osteogenic lineage. Global study of an in vitro osteogenic differentiation potential of the isolated cells was performed using proteomic-based analysis through mass spectrometry with dimethyl labelling method at day 7 and 14 post-induction, comparing with undifferentiated cells. The obtained results could be used as a comprehensive data and principal knowledge of the osteogenic differentiation potential of cBM-MSCs and cDPSCs in vitro and the trend of MSC-based tissue engineering for osteogenic regenerative therapy, concentrating on cMSCs application.

Cerebellar development

Project description:The Affymetrix GeneChip Mu11K was used to analyze the gene expression profile in developing mouse cerebellum (two GeneChips per E18, P7, P14, P21, and P56) to assist in the understanding of the genetic basis of cerebellar development in mice. The analysis showed 81.6% (10,321/12,654) of the genes represented on the GeneChip were expressed in the postnatal cerebellum, and among those, 8.7% (897/10,321) were differentially expressed with more than a two-fold change in their maximum and minimum expression levels during the developmental time course. The expression data (mean signal in relative unit) of all of these 897 differentially expressed genes were listed in GSM50(for E18), GSM51(for P7), GSM52(for P14), GSM53(for P21), and GSM54(for P56) as well as our homepage at http://www.brain.riken.go.jp/labs/lm Keywords = mouse cerebellum development

Expression data for HUVSMC treated with Triptolide

Project description:Transcription of mRNA in mammalian is mainly performed by RNA polymerase II (PolII). POLRMT is responsible for the production of cytoplasmic and nuclear form of mitochondrial RNA polymerase. The former (mtRNAP) participates in transcription of RNA in the mitochondria while the latter (spRNAP-IV) is responsible for some mRNA transcription in the nucleus. The nature and amount of genes transcribed by spRNAP-IV still remains unclear. Thus, we scanned for possible candidate genes by using Affymetrix. HUVSMC cell line was treated with or without 0.3 uM of Triptolide (an inhibitor of PolII) for 24 hours to determine which genes are insensitive to triptolide treatment.
