Drug – Body Interactions
When we talk about drug targets (direct or indirect ), we not only talk about the gene expression, but also t he mutation and the epigenetic status of these targets. All of these factors, together with the drug activity itsel f, affect the efficacy of a therapeutics.

Study Gene Mutations
1. In many cases, cancer drug targets are mutated genes; or else mutated genes affect cell response t o a specific drug, how to identify these gene mutations ?
QIAGEN® works in partnership with Amgen, Merck Serono, and BMS/Lilly/Imclone to develop global companion diagnostics for detecting KRAS mutations to support the anti-EGFR therapies — Vectibix® and Erbitux® —in patients with metastatic colorectal cancer.
2. If you have known a mutant gene as a drug target , is this mutant gene expressed in your samples?

Principle of Cancer Mutation PCR Arrays – DNA Techno logy
.* Real-time PCR is the most sensitive and reliable method for the detection of DNA mutations.
.* Our scientists have developed real-time PCR assays to detect lower than 1% somatic mutations in the background of wild-type DNA templates.
.* Amplification Refractory Mutation System (ARMS®) technology is a strategy in which primers with a mismatched 3’-residue will not function as primers in a PCR reaction. In other words, ARMS-designed primers will preferentially amplify the mutant sequence. The single nucleotide mutations are selected from comprehensive somatic mutation databases (COSMIC) and peer-reviewed scientific literature based on their clinical or functional relevance and frequency of occurrence.

Cancer Mutation PCR Array Design
.Design:
. Cancer Mutation PCR Array is a collection of mutation specific assays for multiple mutations in a single gene, as well as mutations present in genes in downstream signaling activities. . The mutations are selected from comprehensive databases (such as the COSMIC database) and literature reviews based on their clinical or functional relevance and frequency of occurrence.
.Example: EGFR Pathway Somatic Mutation PCR Array – 9 6 well plate• EGFR Mutations: 20 • PI3K Mutations: 7• AKT1 Mutations: 1• PTEN Mutations: 6• KRAS Mutations: 16• HRAS Mutations: 11• NRAS Mutations: 12• BRAF Mutations: 8• MEK1 Mutations: 4

Study the Epigenetic Status of the Genes
.Histone modifications define chromatin structure, a nd correlate closely with the transcriptional activity of the associated genes.
.Adding HDAC (histone deacetylase) inhibitors to a dr ug regimen can greatly change the cell response (e.g. The 4
.FDA-approved epigenetic drugs for clinical use include 2 DNA demethylating agents, 5-
.azacytidine and decitabine, and 2 histone deacetylase (HDAC) inhibitors, vorinostat and
.valproic acid. So far, epigenetic drugs have been approved mainly for the treatment of blood cancers).
Sample & Assay Technologies- 18 -
Introduction to Histone Modification
.Five major families of histone exist: H1, H2A, H2B, H3, H4 and H5. Histones H2A, H2B, H3 and H4 are known as the core h istones, while histones H1 and H5 are known as the linker histones.
.Major modifications of histone include acetylation, methylation, phosphorylation, ubiquitination, and sumoylation. C ombinations of histone modifications constitute a code, the so-cal led “histone code”.
.H3K4me1 means the monomethylation of the 4th residue (a lysine) from the start (i.e., the N-terminal) of the histone H3 protein.
.The common nomenclature of histone modifications is:
. 1. The name of the histone (e.g., H3)
. 2. The single-letter amino acid abbreviation (e.g., K for lysine) and the amino acid position in the protein . 3. The type of modification (me: methyl, p: phosphate, ac: acetyl, ub: ubiquitin)

An Example Experiment with ChIP PCR Array
.Together with our easy and fast EpiTect One-Day ChIP Kit(http://www.sabiosciences.com/chipqpcr_product/HTML/334471.html), ChIP-Grade Antibody Kit (http://www.sabiosciences.com/chipgradeantibody.php), one million cells per assay as starting material, ChIP PCR Arrays provide 100% effective call rates..
.P19 mouse embryonic carcinoma cells were prepared for ChIP Assay using the EpiTect One-Day ChIP Kit and anti-H3K4me3 Antibody Kit. One million cells were used as starting material for each ChIP Assay. The purified ChIP DNA samples were characterized using Mouse Stem Cell Transcription Factor ChIP PCR Array with 1/100th of the ChIP DNA as template in each well. The Real-Time PCR results demonstrate 100 % effective call rates for the Input Fraction (Ct < 30). The difference of Ct value between the anti-H3K4me3 antibody and the control IgG fractions indicates the specific enrichment of the antibody, whereas the high Ct value of the control IgG fraction indicates the low background of the assay.
