Expression data from Botryococcus terribilis ethanol extract (BTEE)-treated RAW264 cells

Gene expression profiling reveals anti-inflammatory effects of BTEE on lipopolysaccharide (LPS)-induced murine RAW264 cells We evaluated the pretreatment effect of BTEE on LPS-induced inflammation in RAW264 cells. Pretreatment with BTEE could significantly attenuate nitric oxide (NO) production and LPS-induced release of inflammatory mediators in RAW264 cells. RNA was extracted using Isogen (Nippon Gene Co. Ltd., Toyama, Japan). The integrity of RNA was quantified using NanoDrop 2000 spectrophotometer (Thermo Scientific, Wilmington, DE, USA). Clariom S assay system (Thermo Fisher, Japan) was used on duplicate RNA samples of each group. In accordance with the user manual, complementary DNA (cDNA) for microarray was generated using the GeneChip WT Plus Reagent kit (Thermo Fisher Science, Japan). Samples were hybridized using Clariom S GeneChip microarray kit (Thermo Fisher Science, Japan). After washing and staining, images were captured, and then CEL data were generated using the GeneChip Scanner 3000 (Thermo Fisher Science, Japan). The raw CEL data were normalized using the transcriptome analysis console (TAC) software ver.4.0.1 following the SST-robust multichip average (SST-RMA) algorithm (Thermo Fisher Scientific, Japan).
