Project description:The differential gene expression study was conducted in the Anti - HMGA2 siRNA treated Retinoblastoma cell (Y79). The transient transfection in Y79 cells were performed using Anti-HMGA2 siRNA . The concentration and the time of incubation for the transfection was optimised to increase the silencing efficiency and reduce the off -target effects. After 48 hours of transfection the cells were collected and the whole genome cDNA microarray was performed to interpret the differential gene expression regulated by HMGA2 in Y79 cells. The results of the microarray data has been validated. One-color experiment,Organism: Human , Custom Whole Genome Human 8x60k designed by Genotypic Technology Pvt. Ltd.

About 45ul of the resulting mixture was applied to the Microarray and hybridized at 65degC for 17 hours in an Agilent Microarray Hybridization Chamber (SureHyb: G2534A) with Hybridization Oven. After hybridization, slides were washed with Agilent Gene expression Wash Buffer I for 1 minute at room temperature followed by a 1 min wash with Agilent Gene expression Wash Buffer II for 37C. Slides were finally rinsed with Acetonitrile for cleaning up and drying. Scan protocol Laser detection of Cyanine 3 and Cyanine 5 fluorescence is performed using a confocal scanning instrument containing two tuned lasers, which excite Cyanine dyes at the appropriate wavelengths. Description Microarrays were scanned on an Agilent scanner (G2565AA) at 100% laser power, 30% PMT.Data extraction was carried out with Agilent Feature Extraction software (version 9.1), and normalization was done using linear per array algorithm according to the manufacturerâs protocol. Data processing Feature extracted data was analyzed using GeneSpring GX v 7.3.1 software from Agilent. Normalization of the data was done in GeneSpring GX using the recommended one color Per Chip and Per Gene Data Transformation: Set measurements less than 0.01 to 0.01, Per Chip: Normalize to 50th percentile, Per Gene: Normalize to Specific Samples. Further quality control of normalized data was done using correlation based condition tree to eliminate bad experiments. Differentially regulated Genes were filtered with cutoff of > 1.5 for Up regulation and < 0.55 for Down Regulation were obtained. Differentially regulated genes were clustered using gene tree to identify significant gene expression patterns.
