Tanshinone I inhibit normal and malignant hematopoiesis by repressing EZH2 activity [human]

Project description:Purpose: To explore the mechanism of how Tan I inhibits malignant hematopoiesis at the gene expression level Methods: NB4 cells treated with DMSO or Tan I 10 μM were collected for RNA sequencing Results: We found that 376 genes were differentially expressed between DMSO and Tan I treatment in the NB4 cells (p value <=0.05, |log2 fold change| >= 0.25) Conclusions: We identified MMP9 and ABCG2 as two possible downstream genes of Tan I’s effects on EZH2

RNA profiling of genistein and Tanshinone I treated cervical cancer cells

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.

Tanshinone I, a new EZH2 inhibitor restricts normal and malignant hematopoiesis through upregulation of <i>MMP9</i> and <i>ABCG2</i>.

Project description:Rationale: Tanshinone, a type of diterpenes derived from salvia miltiorrhiza, is a particularly promising herbal medicine compound for the treatment of cancers including acute myeloid leukemia (AML). However, the therapeutic function and the underlying mechanism of Tanshinone in AML are not clear, and the toxic effect of Tanshinone limits its clinical application. Methods: Our work utilizes human leukemia cell lines, zebrafish transgenics and xenograft models to study the cellular and molecular mechanisms of how Tanshinone affects normal and abnormal hematopoiesis. WISH, Sudan Black and O-Dianisidine Staining were used to determine the expression of hematopoietic genes on zebrafish embryos. RNA-seq analysis showed that differential expression genes and enrichment gene signature with Tan I treatment. The surface plasmon resonance (SPR) method was used with a BIAcore T200 (GE Healthcare) to measure the binding affinities of Tan I. In vitro methyltransferase assay was performed to verify Tan I inhibits the histone enzymatic activity of the PRC2 complex. ChIP-qPCR assay was used to determine the H3K27me3 level of EZH2 target genes. Results: We found that Tanshinone I (Tan I), one of the Tanshinones, can inhibit the proliferation of human leukemia cells in vitro and in the xenograft zebrafish model, as well as the normal and malignant definitive hematopoiesis in zebrafish. Mechanistic studies illustrate that Tan I regulates normal and malignant hematopoiesis through direct binding to EZH2, a well-known histone H3K27 methyltransferase, and inhibiting PRC2 enzymatic activity. Furthermore, we identified MMP9 and ABCG2 as two possible downstream genes of Tan I's effects on EZH2. Conclusions: Together, this study confirmed that Tan I is a novel EZH2 inhibitor and suggested MMP9 and ABCG2 as two potential therapeutic targets for myeloid malignant diseases.

The anticancer effects of tanshinone I in human non-small-cell lung cancer

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. Keywords: treatment with dose respone, cDNA array

Expression data from five human leukemia cell lines treated with DMSO or tanshinone IIA

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). 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.
