(Submitter supplied) Previous studies indicate that the triterpene glycoside actein from the herb black cohosh inhibits growth of human breast cancer cells. This study seeks to identify genes altered in human breast cancer cells by treatment with actein, using gene expression analysis. We treated MDA-MB-453 human breast cancer cells with actein at 2 doses, 20 or 40 μg/mL, for 6 or 24 h. We identified 5 genes that were activated after each of the treatments that are known to play a role in cellular responses to diverse stresses, including the DNA damage and unfolded protein responses. more...

Analysis of MDB-MB-453 breast cancer cells treated with 20 or 40 ug/ml actein for 6 or 24 hours. Actein is a triterpene glycoside from the herb black cohosh and inhibits the growth of cancer cells in vitro. Results provide insight into the molecular basis of this inhibitory effect.

(Submitter supplied) Gamma tocotrienol induces apoptosis in breast cancer cells however, the molecular mechanisms are not completely understood. We used microarrays to detail the global programme of gene expression underlying the effects of gamma tocotrienols on MCF-7 cells and identified distinct classes of up-regulated genes during this process.

Analysis of MCF-7 cells treated with gamma-tocotrienol (γ-T3). Tocotrienols (T3s) inhibit the growth of various cancer cell lines without affecting normal cells. Results provide insight into the molecular mechanisms of action of T3s on cell death and other growth inhibitory pathways.

(Submitter supplied) Extracts from the rhizome of Cimicifuga racemosa (black cohosh) are increasingly popular as herbal alternative to hormone replacement therapy (HRT) for the alleviation of postmenopausal disorders. However, the molecular mode of action and the active principles are presently not clear. Previously published data have been largely contradictory. We, therefore, investigated the effects of a lipophilic Cimicifuga rhizome extract on the ER+ breast cancer MCF-7 cells at transcriptional level in comparision to 17beta-estradiol and the ER antagonist tamoxifen. more...

(Submitter supplied) 17β-HSD1 expression modulates T47D transcript profile in in steroid-deprived medium. The enzyme specifically regulates apoptosis and cancer-related genes in T47D cells cultured in steroid-deprived medium. Genes that primarily involved in Cell cycle progression, such as the Cyclin A2 gene, CCNA2, are generally down-regulated whereas most genes involved in apoptosis and cell death, such as the proapoptotic gene XAF1 and FGF12, are on the contrary up-regulated by 17β-HSD1 knockdown, and 21% of the modulated genes belong to this latter functional category. more...

(Submitter supplied) Cancer-host interactions play an important role in cancer development. We identified ATF3, an adaptive-response gene, in the host to facilitate metastasis. We also demonstrated that the macrophage is one of the key cell types for host-ATF3 to function. Furthermore, matrix metalloproteases 9 is a functionally important target gene of ATF3 in co-culture assays. Gene profiling with bioinformatics analyses indicated that ATF3 downstream gene-signatures derived from tumor-associated macrophages in a mouse model can distinguish human tumor stroma from “distant” stroma in and can stratify the patients into high- versus low-risk groups. more...

(Submitter supplied) Maintenance of genetic integrity is essential for survival of all organisms. Activating transcription factor 3 (ATF3) is a member of the c-AMP response element binding (CREB)/ATF family of transcription factors, and is highly inducible by various stress conditions including DNA damage. However, downstream targets and molecular basis underlying pleiotropic effects of ATF3 on the cell fate have been largely unknown. more...

(Submitter supplied) Comprehensive analysis of global ATF3-binding profiles in the human genome under quiescent and stressed (DNA damage) conditions. Although expressed at a low level, quiescent ATF3 was found to bind a large number of genomic sites that are often associated with genes required for cellular stress responses. While these ATF3-binding sites often contained motifs for other transcription factors (TFs), we found that ATF3 bound a large portion of active enhancers characterized by p300 binding, and as a consequence, ATF3 often regulates expression of the genes proximal to these enhancers. more...
