Mouse Stem Cell Transcription Factors PCR Array
The Mouse Stem Cell Transcription Factors RT² Profiler™ PCR Array profiles the expression of 84 key genes associated with stem cell differentiation and development. During development, a few key transcription factors (NANOG, POU5F1, and SOX2) drive embryonic stem cell maintenance. These genes activate or repress other key transcription factors represented by this array that are necessary for development and differentiation, forming a transcriptional regulatory network. For example, embryonic stem cell maintenance requires POU5F1 (OCT4), whereas trophectoderm development requires CDX2. These two genes repress each other, forming a regulatory network that either delays development or allows it to proceed as signaled. Understanding these regulatory loops is essential to decipher developmental transcriptional networks and ultimately elucidate differentiation mechanisms. This array includes key transcription factors necessary for stem cell maintenance, as well as transcription factors and cofactors involved in and regulated during developmental processes. Using real-time PCR, you can easily and reliably analyze the expression of a focused panel of transcription factors involved in stem cell differentiation and development with this array. The RT² Profiler PCR Arrays are intended for molecular biology applications. This product is not intended for the diagnosis, prevention, or treatment of a disease. 96-well Plate, 384-well (4 × 96) Plate, and 100-well Disc formats are available.

"If you have access to a real-time PCR instrument, you can use PCR Arrays"

RT² Profiler™ PCR Arrays are the most reliable and sensitive gene expression profiling technology for analyzing a panel of genes in signal transduction pathways, biological process or disease related gene networks. The PCR Arrays can be used for research on cancer, immunology, stem cells, toxicology, biomarker discovery and validation, and phenotypic analysis of cells and transgenic animals. See the complete list of PCR Arrays.

You can use any 96-well or 384-well real-time PCR instrument. See instrument-specific setup instructions. Click below for detailed information.

How it Works

The PCR array is a set of optimized real-time PCR primer assays on 96-well or 384-well plates for pathway or disease focused genes as well as appropriate RNA quality controls. The PCR array performs gene expression analysis with real-time PCR sensitivity and the multi-gene profiling capability of a microarray. Simply mix your cDNA template with the appropriate ready-to-use PCR master mix, aliquot equal volumes to each well of the same plate, and then run the real-time PCR cycling program.

Performance Data Sensitivity:
The complete PCR Array System yields a greater-than 85 percent present call with as little as 25 ng as much as 5 µg of total RNA from a pathway representing genes expressed at a lower level (inflammatory cytokines and receptors).

Figure 2:	PCR Arrays Let You See More Genes with Less RNA Different amounts of universal total RNA were characterized using the Human Inflammatory Cytokines and Receptors PCR Array, and the percentage of detectable genes was calculated for each RNA amount. As little as 25 ng total RNA yields greater than an 80% positive call, even for cytokines expressed at very low levels.

Reproducibility
The complete PCR Array System demonstrates strong correlations across technical replicates, lots, and instruments with average correlation coefficients > 0.99 insuring reliable detection of differences in expression between biological samples.

Figure 3:	PCR Arrays Yield Highly Reproducible Results Four replicate sets of raw threshold data (1-4) obtained by two different scientists (A & B) at two different times (050825 & 060111) on Human Drug Metabolism RT² Profiler PCR Arrays are directly compared. The results demonstrate a high degree of correlation (R² > 0.990).

Specificity
The complete PCR Array System, with high quality input RNA, is guaranteed to yield single bands of the predicted size without primer dimers or other secondary products thus providing the most accurate real-time PCR results possible.

Universal total RNA was characterized on the TGFβ / BMP Signaling Pathway PCR Array, followed by dissociation (melt) curve analysis. PCR Arrays specifically detect individual genes despite the expression of related gene family members in the same RNA sample.

Application Data

Cancer Research:
To ascertain the oncogenic route that two different human breast tumors have taken, the relative expression level of cancer- and adhesion-related genes in normal and two different cancerous tissues were compared.

Template cDNAs prepared from total RNA of normal human breast and two human breast tumors (BioChain Institute, Inc., 5.0 µg) were characterized in technical triplicates using the Human Cancer PathwayFinder™ PCR Array and the Human Extracellular Matrix & Adhesion Molecule PCR Array with the RT² SYBR Green / Fluorescein PCR master mix on the Bio-Rad iCycler®.

Figure 5: ECM & Adhesion PCR Arrays Revealed Up- and Down-Regulated Genes in Breast Cancer
Total RNA from normal human breast and a human breast tumor were characterized in technical triplicates, and the relative expression levels for each gene in the two samples are plotted against each other in the Scatter Plot. Genes encoding the matrix metallopeptidases (MMP3 & MMP9) and their inhibitors (TIMP3) are up-regulated, while genes encoding integrins (ITGB3 & ITGB4) are down-regulated, by at least three-fold (outside the silver field) in breast tumors relative to normal tissue.

Toxicology Research:
Rezulin (Troglitazone or "Tro" or "T"), a glitazone PPAR-gamma agonist, was approved for treatment of type 2 diabetes mellitus, but was withdrawn from the market due to idiosyncratic liver toxicity. Two similar drugs, Avandia (Rosiglitazone or "Rosi" or "R") and Actos (Pioglitazone or "Pio" or "P"), are considered to be safe treatments for the same condition. The expression profile of key drug metabolism genes should be different in cells treated with Rezulin versus those treated with Avandia and Actos.

Hepatocellular carcinoma HepG2 cells were treated at 80% cell confluence with these three drugs (100 µM, Cayman Chemical) or a DMSO vehicle control for 24 h. RNA isolated using the ArrayGrade™ Total RNA Isolation Kit was used to characterize gene expression with the Human Drug Metabolism and Stress & Toxicity PathwayFinder™ RT² Profiler™ PCR Arrays and RT² SYBR Green / Fluorescein PCR master mix on the Bio-Rad iCycler®.

Figure 6: Stress & Toxicity PathwayFinder™ PCR Array Uncovered Idiosyncratic Mechanisms of Action for Liver Toxicity Caused by 3 PPARγ Agonists.
RNA from HepG2 cells treated with three different glitazone PPARγ agonists for type 2 diabetes mellitus was characterized, and the results were compared to that of a vehicle (DMSO) control. A withdrawn drug with idiosyncratic liver toxicity (Rezulin) induces very different changes in the expression of stress-related genes than two safer drugs still on the market (Avandia and Actos).
