Sample GSM1211056 Query DataSets for GSM1211056
Status Public on Oct 31, 2013
Title Cultured HSCs-LPS-24h-rep1
Sample type RNA
Source name Cultured HSCs-LPS-24h-rep1
Organism Rattus norvegicus
Characteristics cell type: Primary cultured rat hepatic stellate cells
gender: Male
Treatment protocol Cultured HSCs were treated with 10 ng / mL (final concentration) of LPS for 1h, 3h, 6h, 12h or 24h. Vehicle-treated controls were harvested at 1h or 24h.
Growth protocol Isolated HSCs were plated at a density of 0.5 x 10^6 cells/cm^2, and the medium renewed after overnight culture and then on alternate days. The cells were used on day 7 of culture when the majority expressed α-sma but contained abundant retinoids
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from cultured cells using an RNeasy Mini kit (Qiagen, Valencia, CA)
Label biotin
Label protocol Total RNAs were amplified and labeled using Affymetrix products [catalog #s 900371 / 900431 / 900433 / 900449] now superseded by 3' IVT Express Kit (Affymetrix Inc., Santa Clara, CA)
Hybridization protocol Following fragmentation, 15 ug of cRNA were hybridized for 16 hr at 45C on Affymetrix Rat Genome 230 2 array. GeneChips were washed and stained in an Affymetrix Fluidics Station 400.
Scan protocol Stained microarrays were scanned with a Affymetrix GeneChip Scanner 3000
Data processing The raw data obtained from microarray analysis were processed using Affymetrix GeneChip Operating Software (GCOS v 1.4) using software defaults, to assess the presence or absence of each transcript target sequence, its expression level, and then to make all relevant pair-wise statistical comparisons among samples. Expression levels were scaled to a target value of 500 using the software default (2% trimmed mean). Prior to scaling, global microarray signals were 279 ± 73 (mean ± SD, n = 11)
