Incyte corporation expression microarray
Overview of the production and use of expression microarrays. 3′ Expression arrays use synthetically derived oligo probes with design based on mRNA Databases (RefSeq mRNAs, GenBank mRNAs, and ESTs from dbEST) or cDNA derived from bacterial libraries (see ). Sample mRNA can be labeled using two methods (a) Cy3/Cy5 labeling: sample mRNA is reverse transcribed into cDNA and Cy3 is added to one sample and Cy5 to another. Both labeled samples are hybridized to the same <t>microarray.</t> (b) 3′ IVT array: sample mRNA is reverse transcribed to cDNA using oligo(dT) primers, to provide a template for transcription. Using biotin-conjugated nucleotides, the template cDNA is then converted to amplified RNA (aRNA). The biotin-labeled aRNA samples are then fragmented and hybridized onto 3′ expression arrays. A biotin binding fluorescent stain is added to the microarray after hybridization. (c) Affymetrix HuExon 1.0 ST: sample mRNA is reverse transcribed to cDNA using random primers, to provide a template for transcription. The resulting RNA is then reverse transcribed in the presence of dUTPs which are incorporated occasionally into the cDNA sequence instead of dTTP. An enzyme is then used to cleave the cDNA at the site of dUTP incorporation and fragments are terminally labeled before hybridization onto the array. The microarray is then washed and stained after hybridization.

ABCG2 upregulation is associated with SIK3 attenuation. (A) List of ABC family proteins from <t>microarray</t> data for which the expression changed more than 1.5-fold compared with control cells. (B) The mRNA expression levels of ABC proteins were verified by real-time PCR in OVCAR4 and SKOV3 cells. The white bar (shLuc) represents control cells, and the gray bar (shSIK3#01) and black bar (shSIK3#61) represent indicated cells with SIK3 knockdown. Data are represented as the mean ± SEM from three independent experiments and analyzed by one-way ANOVA. *: p <0.05 and **: p <0.01 (compared to the shLuc control). Note that ABCG1 and ABCG2 were both significantly upregulated in cells with SIK3 knocked down by shSIK3#01 and shSIK3#61. (C) The protein expression levels of ABCG1 and ABCG2 were further verified by Western blotting. Note that only ABCG2 was upregulated in OVCAR4 and SKOV3 cells with SIK3 knocked down by shSIK3#01 and shSIK3#61. (D) The functional MDR activity of the ABCG2 protein was determined using an MDR assay kit (Abcam). A total of 2 x 10 5 suspended cells were pretreated with the inhibitor novobiocin (50 nM) or DMSO. Then, diluted Efflux Gold Detection Reagent was added at 37°C for 30 minutes. The cellular orange fluorescence signal of the Efflux Gold Detection Reagent was measured immediately by flow cytometry in the living (PI-negative) cell population. The numbers in the upper left corners are MAF values.
