Project description:The aim of this study was to analyze the influence of PADMA28 ethanolic extracts on HepG2 gene expression. PADMA28 (Swissmedic Nr. 58436) is an Indo-Tibetan polyherbal preparation used for the treatment of symptoms associated with circulatory disorders. Triplicate cultures of HepG2 cells were treated with either PADMA28 or EtOH solvent control for 18 hours. After cell harvest, the triplicates were pooled and total RNA was extracted. The RNA was analyzed using Affymetrix Human Genome U133 Plus 2.0 microarrays (one array per treatment).

Project description:The MCF-7 were infected with either control adenovirus expressing B-galactosidase (Ad) or adenovirus expressing ERB (AdERbeta) for 72 h. For knockdown of the endogenous ERa in MCF-7 cells, cells were treated with siRNA for 24h (AdERbeta+SiERalpha). Then cells were treated with Veh (0.1% EtOH), 10 nM E2 or 1 uM BEs (botanical extracts) for 24h.
Project description:We performed microarray analysis to examine the differential gene expression profiles between Prdm1 (Blimp-1)-deleted and control keratinocytes. Keratinocytes isolated from Prdm1-floxed K5-CreER positive (CKO) mice were cultured in the presence of 4OHT to induce deletion of the Prdm1 allele in vitro. Prdm1-floxed K5-CreER positive (CKO) keratinocytes treated with the ethanol solvent control (EtOH) or Prdm1-floxed K5-CreER negative (control) keratinocytes treated with 4OHT or EtOH served as controls. Microarray analyses revealed that there were 93 genes up-regulated and 109 genes down-regulated by more than 2-fold in the CKO + 4OHT group in comparison with the CKO + EtOH, Ctrl + 4OHT or Ctrl + EtOH groups. Several corneocytes-related genes, including Rptn, Lce1f, Krt1 and Lce1d, are significantly down-regulated and several cytokines/chemokines, including Cxcl1, Cxcl2, Cxcl5 and Il24, are significantly up-regulated upon the deletion of Prdm1 in vitro.
Project description:we treated the HepG2 cells with low concentration or control solvent for a long time. Then we extracted the RNAs and performed the next generation sequencing. By comparing sequcing data from control and DEHP treated samples, we profiled the gene expression regulated by low concentration exposure.
Project description:LNCaP cells are an established androgen receptor expressing prostate carcinoma cell line. Human foreskin fibroblasts also expressing the androgen receptor were obtained from phenotypic normal male individuals. Cells were cultured either at confluency leading to G0 cell cycle state or while they were proliferating. Cells were either untreated, or treated with dihydrotestosterone (DHT) or ethanol (ETOH) which also served as the solvent for the DHT. All experimental RNA samples derived from the untreated or treated cell lines were hybridized on cDNA arrays against a common reference. This reference was composed out of common reference CRG (50%) and out of fibroblast RNA (50%). This reference is also called "mixed reference" in the description of the 26 individual experiments. A strain or line experiment design type assays differences between multiple strains, cultivars, serovars, isolates, lines from organisms of a single species. Compound Based Treatment: dihydrotestosterone (DHT) or ethanol (ETOH = solvent) Cell Line: genital fibroblast cell line or prostate carcinoma cell line (LNCaP) Culture Synchrony: Go or proliferation Keywords: strain_or_line_design
