RNA profiling of genistein and Tanshinone I treated cervical cancer cells

ABSTRACT: 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.

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.

Genistein treatment effects upin human prostate

Project description:Prior studies support the notion that the experimental chemopreventive agent, genistein, inhibits prostate cancer (PCa) cell movement in humans and that this in turn inhibits metastatic spread, thereby preventing PCa-specific death. As many effects have been ascribed to genistein, it has been considered a non-specific agent. However, its effects are concentration-dependent, and the vast majority of studies use concentrations greater than 3 logs above those associated with dietary consumption. Genistein is found in soy, and individuals consuming soy-based diets have blood concentrations of free genistein in the low nanomalar range. Using dosing guided by phase I pharmacokinetic studies in US men, prospective treatment of men on a phase II trial with genistein for one month prior to radical prostatectomy for localized PCa. Here we conducted an unbiased screening for effects of genistein in prostate as well as evaluate changes between normal and cancer cells.

Quantitative Phosphoproteomics Reveals Genistein as a Modulator of Cell Cycle and DNA Damage Response Pathways

Project description:Around one sixth of breast cancer cases are classified as triple-negative breast cancer (TNBC), named after the absence of the expression of estrogen receptors (ER), progesterone receptors (PR), and human epidermal growth factor receptor 2 (HER2); however, patients with TNBC suffer from poor clinical outcome and shortage of targeted therapy. Genistein, an estrogenic soy isoflavone, shows anti-cancer effects in TNBC cells such as inducing G2/M cell cycle arrest and apoptosis. However, the underlying mechanism of its anti-cancer effects is poorly understood and its elucidation can help the development of novel therapeutic strategies for TNBC. In this study, by combining isobaric tag-based TMT labeling with titanium dioxide-based phosphopeptide enrichment, we quantitated 5,445 phosphorylation sites on 2,008 phosphoproteins in a TNBC cell line, MDA-MB-231, upon genistein treatment. Our analysis revealed 332 genistein-regulated phosphorylation sites on 226 proteins. Our data show that genistein can regulate several biological processes during the cell cycle, including DNA replication, cohesin complex cleavage, and kinetochore formation. In the meantime, genistein can also activate DNA damage response, including activation of ATR and BRCA1 complex. Overall, for the first time, our study present the evidence that genistein could inhibit TNBC cell growth by regulating the cell cycle and DNA damage response. Our findings help elucidate the mechanisms through which genistein exerts its anti-cancer effects in TNBC cells.

Genome-wide microarray analysis of normal human fibroblasts in response to kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein

Project description:Establishment of a transcriptomic profile of human cells treated with kaemferol, daidzein, kaemferol/genistein, or daidzein/genistein with particular emphasis on signature of genes coding for enzymes involved in glycosaminoglycan synthesis stands for the present study. The hypothesis tested was that kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein influence expression of some genes, among which are those coding for enzymes required for the synthesis of different GAGs being pathologically accumulated in mucopolysaccharidoses. Results provide important information concerning the extent of action of kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein at the molecular level in terms of modulation of gene expression.

A quantitative proteomic based approach to study the genistein induced epigenetic reprogramming in MDA-MB231 cells

Project description:Epidemiological data indicate that consumption of soy-based food significantly reduces the cancer risk in human through interaction with estrogen receptors and the ‘phytoestrogen’ genistein present in the soy is responsible for this chemopreventive activity. The epigenome regulatory effect of genistein also reported but the key mechanism behind this effect remain elusive. In this current project, we reported the epigenome modulation effect of genistein using MDA-MB231 cells. Cells were treated with low-dose genistein for >1 month and the stable epigenetic alterations were analyzed by partial MNase digestion and TMT-based quantitative proteomics based chromatome mapping approach. We identified a total of 3177 chromatin-bound proteins with high confidence, including 882 proteins that displayed altered binding topology after cell conditioning with genistein. Prolonged phytochemical exposure permanently modified the binding topology of the key epigenetic regulators and preserved their binding topology in untreated progeny. Genistein induced altered epigenome modulation negatively regulates the expression of cell proliferation genes and suppress cell growth. In contrast, previously exposed cells displayed reduced expression of DNA repair genes and enhanced genotoxic stress upon genistein withdrawal.

ERβ activation by genistein promotes metastatic progression in prostate cancer

Project description:Androgen signalling through the androgen receptor (AR) plays a critical role in prostate cancer (PCa) initiation and progression. Estrogen and the estrogen receptor, in synergy with androgen, are essential for cell growth of the normal and malignant prostate. However, the exact role that estrogen plays in prostate carcinogenesis, and the precise mechanisms involved, remain unclear. We have previously demonstrated the metastasis-promoting effect of an estrogen receptor Beta (ERβ) agonist (genistein) and the inhibitory action of an anti-estrogen (ICI 182, 780) in patient-derived PCa xenograft models mimicking localized and metastatic disease. In this study, we compared the gene expression profiles of treated and untreated PCa xenografts using microarrays to identify a unique set of genes that were both up-regulated by genistein treatment and down-regulated by the anti-estrogen, ICI 182,780. Five of the six genes identified from this comparison belonged to the metallothionein (MT) gene family. Knock-down of ERβ led to a reduction in MT gene expression, confirming its role in regulating these genes. Using qRT-PCR, the differences in expression levels were validated in the metastatic and non-metastatic LTL313 PCa xenograft tumour lines, both of which were originally derived from the same PCa patient. Together our data provides evidence for the role of ERβ signalling in PCa metastasis and implicates estrogen-stimulated MT gene expression in this process. Three samples each (total RNA extracted from three tumours of three different animals from each group) for control, genistein and ICI were used for the array.

Genome-wide expression profiling of prostate specimens from a clinical trial of genistein supplementation prior to prostatectomy.

Project description:To identify molecular effects of genistein on mRNA levels in prostate cancer, we compared gene expression profiles of genistein-treated tumors with placebo-treated samples. There were 628 probes that reached nominally significant p-values. The genes that were differentially expressed between genistein and placebo samples were involved in angiogenesis, apoptosis, epithelial to mesenchymal transition, and tumor progression. Gene enrichment analysis suggested that PTEN and PDGF were activated, while MYC, beta-estradiol, glucocorticoid receptor NR3C1, and interferon-gamma were repressed in response to genistein treatment. These findings highlight the effects of genistein on global changes in gene expression in prostate cancer and its effects on molecular pathways involved in prostate tumorigenesis.

Genistein in Treatment of Metastatic Colorectal Cancer

Project description:Colorectal neoplasms are the third most common malignancies in the United States. Patients with metastatic (stage IV) colorectal cancer have a median life expectancy of 2 years. The response rates to chemotherapy range from 35-40%. Epidemiologic evidence suggests that soy compounds may reduce the incidence of colorectal cancers. Laboratory analyses demonstrate that genistein, a soy-derived compound, may inhibit Wnt signaling, a pathway activated in majority of colorectal cancers. Laboratory observations also demonstrate that genistein may augment growth inhibition when combined with chemotherapeutic agents of 5-Fluorouracil and platinum compounds. Based on pre-clinical data the investigators hypothesize that combining genistein with the standard of care chemotherapeutic regimens will reduce chemotherapy resistance and improve response rates in patients. The aim of the study is to add genistein to the regimens of FOLFOX or FOLFOX-Avastin in patients with newly diagnosed stage IV colon or rectal neoplasms.

Genome-wide DNA methylation profiling of prostate specimens from a clinical trial of genistein supplementation prior to prostatectomy.

Project description:To identify molecular effects of genistein on DNA methylation in prostate cancer, we compared DNA methylation profiles of genistein-treated tumors with placebo-treated samples. There were 156 probes with significantly increased methylation in placebo-treated cases versus normal tissues that were not significant between genistein-treated cases and normal tissues, suggesting that genistein may have had some demethylation effects. These 156 probes corresponded to at least 92 separate genes including ADCY4, ALOX12, HAAO, LRRC4, NEU1, RAPGEFL1, and WNT7B.These findings highlight the effects of genistein on global changes in DNA methylation in prostate cancer and its effects on molecular pathways involved in prostate tumorigenesis.
