Mouse TGF / BMP Signaling Pathway DNA Methylation PCR Array, Signature Panel: MeAM-351
The Mouse TGF / BMP Signaling Pathway EpiTect Methyl DNA Methylation PCR Arrays profile the promoter methylation status of a panel of 24 promoters of genes involved in TGF and BMP-mediated signaling during carcinogenesis and cellular differentiation. The TGF signaling pathway suppresses tumor growth early in oncogenesis, but then stimulates metastasis in later stages. Cancer genomes often demonstrate hypermethylation and silencing of genes encoding members of this pathway, from receptors (TGFBR2) to transcription factors (SMAD4). Profiling your cellular or fresh tissue genomic DNA samples with these arrays will help you correlate CpG island methylation status with biological phenotypes. The results can also provide further insights into how TGF signaling contributes to carcinogenesis and cellular differentiation. With a simple restriction enzyme digestion and real-time PCR on your 96- or 384-well instrument, you can analyze the promoter methylation status of 24 different TGF / BMP Signaling Pathway members with the DNA Methylation PCR Arrays.

Both 96-well and 384-well ( 4 X 96 ) formats are available.

The EpiTect Methyl qPCR Arrays use the MethylScreen™ Technology provided under license from Orion Genomics, LLC.

  "If you have access to a real-time PCR instrument, you can analyze the methylation status of multiple genes at the same time using the EpiTect Methyl qPCR technology."

The EpiTect Methyl qPCR Array System is a fast, reliable technology that profiles the DNA methylation status of a panel of genes. These PCR Arrays can help you discover and verify cancer or developmental biomarkers useful for both basic and applied research. No bisulfite conversion is required, and the challenges of real-time PCR primers design and optimization has already been done for you. EpiTect Methyl qPCR Arrays are ideal for fast, high-throughput methylation analysis. For determining the exact methylation level of individual and consecutive CpG sites, we recommend using bisulfite Pyrosequencing on a PyroMark system.

You can use any 96-well or 384-well real-time PCR instrument.

How it Works Performance Data Application Data

How it Works

The EpiTect Methyl qPCR Array System relies on the differential cleavage of target sequences by two different restriction endonucleases whose activities require either the presence or absence of methylated cytosines in their respective recognition sequences. As real-time PCR quantifies the relative amount of DNA remaining after each enzyme digestion, the methylation status of individual genes and the methylation profile across a gene panel are reliably and easily calculated. The high yield of DNA from the restriction digests and PCR amplification allow the analysis of smaller, more heterogeneous samples.

Array Layout:
The PCR Arrays are available in both 96- and 384-well plate formats to analyze the methylation status of 24 or 96 genes related to a disease state, such as specific types of cancer, or development pathways related to specific cells or tissues. The Signature panels of 24 genes are arranged on either 96-well or 384-well plates to simultaneously characterize all four restriction digests from either one or four different DNA samples, respectively. The more Complete panels of 96 genes are arranged on 96- or 384-well plates to characterize all four restriction digests from one DNA sample either on four plates or all on the same plate, respectively.

For more detail on PCR Array layout, see the "Gene Table" link for the individual array products.

Performance Data

To verify the reliability of the EpiTect Methyl qPCR Array System, its results and sensitivity were compared with bisulfite Sanger sequencing, the gold standard in DNA methylation analysis.

Same Results as Sanger Bisulfite Sequencing

EpiTect Methyl qPCR Yields Results Identical to Sanger Bisulfite Sequencing.
The methylation status of the cadherin 1 (CDH1) gene promoter was analyzed using either bisulfite sequencing or EpiTect Methyl qPCR Primer Assays in three different breast cancer cell lines known to have very different CDH1 methylation patterns.

Same Sensitivity as Sanger Bisulfite Sequencing
Primary tumors are typically very heterogeneous, containing a mixture of both cancerous and noncancerous cells. Therefore, reliable tumor characterization requires detecting smaller amounts of hypermethylated DNA diluted in an unmethylated background.

EpiTect Methyl qPCR Detects Hypermethylation in Heterogeneous Samples Containing As Little As Five Percent Tumor DNA.
SKBR3 breast cancer cell line and normal blood genomic DNA (encoding hypermethylated and unmethylated HIC1, respectively) were mixed in different ratios. Using Human HIC1 EpiTect Methyl qPCR Primers, the percentage of hypermethylated HIC1 relative to total promoter DNA in each mixture was detectable even down to five percent of the total DNA sample.

Application Data

Gene promoter methylation is the most common epigenetic mechanism silencing tumor suppressor genes during oncogenesis. Almost all cancer-related signaling pathways are affected by methylation, and the number of genes affected in each major type of cancer is still rapidly growing. However, even the most relevant genes have not yet been correlated to individual cancer types or subtypes in order to better define biological pathways and mechanisms leading to oncogenesis and in order to properly develop DNA methylation biomarkers. The expenses related to screening large numbers of genes in many tumor samples simultaneously using a bisulfite-based method are not practical. The EpiTect Methyl qPCR System provides an ideal reagent for such studies. The following experiments demonstrate that DNA Methylation PCR Arrays can both verify known and discover new DNA methylation cancer biomarkers. For determining exact methylation levels of specific CpG sites, we recommend using bisulfite Pyrosequencing on a PyroMark system.

Biomarker Verification

EpiTect Methyl qPCR Arrays Verify Breast Cancer Gene Methylation Status in Breast Cancer Cell Lines.
The heat map compares the hypermethylation status of 24 genes in the genomic DNA of three breast cancer cell lines and blood genomic DNA (used as an unmethylated control) determined with the Human Breast Cancer Signature Panel DNA Methylation PCR Arrays. The results further strengthen the correlation of these biomarkers with breast cancer.

Biomarker / Pathway Discovery
Cancer progresses through aberrant cell differentiation due to alterations in gene expression. Transcription factors regulate gene expression, and many tumor suppressor genes and oncogenes, defined by classical genetic methods, encode transcription factors. Does the methylation status of transcription factor genes differ between cancer and normal cells?

EpiTect Methyl qPCR Arrays Discover New Candidate Breast Cancer DNA Methylation Biomarkers.
The heat map compares the hypermethylation status of a panel of 79 transcription factor genes in six different breast cancer cell lines (some in duplicate) and a normal epithelial cell line as determined using 384-well Custom DNA Methylation PCR Arrays. These breast cancer cell lines also hypermethylate this gene panel potentially providing a new source of cancer biomarkers.

These results are consistent with the notions that aberrant expression of transcription factors controlling cell differentiation plays key roles in oncogenesis and that transcription factors can be tumor suppressors.
