Promega and SwitchGear Publish Findings from Combined Technologies that Correlate Binding Events and Transcriptional Activity
Madison, WI (November, 18, 2009) — Promega Corporation and SwitchGear Genomics announce a novel method for characterizing DNA-protein interactions. Results of a study using the HaloCHIP™ System and high-throughput promoter assays demonstrate the ability to correlate DNA binding events to transcriptional activation or repression for the CREB transcription factor. The findings appear in the article “A functional analysis of the CREB signaling pathway using HaloCHIP-chip and high throughput reporter assays“, recently published in BMC Genomics online.
This combination of technologies enables discovery of genome-wide DNA binding sites for transcription factors and the functional activities of the promoter sequences bound by those transcription factors. “This comprehensive approach enables the comparison between binding events and transcriptional activity,” said Nathan Trinklein, Ph.D., co-founder and CEO of SwitchGear Genomics. “Characterizing the functional consequences of binding events is essential to more fully understanding the control of gene expression.”
HaloCHIP, which uses Promega HaloTag® Technology, eliminates the need for antibodies to capture protein:DNA complexes, thereby avoiding one of the major challenges of chromatin immunoprecipitation (ChIP) techniques.
“HaloCHIP allows researchers to more easily and efficiently capture genome-wide protein-DNA complexes starting with a much smaller number of cells,” stated Danette Hartzell, Senior Research Scientist at Promega Corporation. “This antibody-free method for revealing DNA binding events in combination with functional reporter assays can significantly advance gene regulation studies.”

SwitchGear Genomics launches novel high-throughput screening products for profiling biological pathway regulation
Collections of experimentally-validated human promoter reporter vectors empower researchers to measure transcriptional regulation across genes in a variety of different biological pathways
MENLO PARK, Calif. – October 14, 2009 – SwitchGear Genomics, Inc., a leading provider of products for studying regulatory elements in the human genome, today announced the availability of the first cost-effective, high-throughput research tools for screening transcriptional activation and repression in a number of key biological pathways. The new SwitchGear pathway sets utilize experimentally-validated luciferase reporter vectors to accurately quantify human promoter activity from complete sets of genes associated with inflammation, cholesterol biosynthesis, oncology, vascular biology, nuclear hormone receptor signaling, and many other important biological pathways.
"The SwitchGear panels of human promoter targets was selected from our genome-wide reporter collection of promoters using motif analysis and published functional genomic data sets," said Shelley Force Aldred, co-founder and President of SwitchGear Genomics, Inc. "We then performed pathway-specific inductions to create an activity profile across the set of constructs. We offer complete pathway profiling sets of constructs in high-throughput plate formats that empower researchers to efficiently profile the effects of many compounds and conditions." In addition, the company provides a smaller subset of "key responder" promoter constructs that showed a strong induction response in the experiments and which may be used as biomarkers in primary screening applications.
Researchers at the National Institutes of Health screened over 1400 compounds to test hypoxia pathway stimulation and published the results in an article entitled "Identification of Chemical Compounds that Induce HIF-1alpha Activity." The screening process, including the use of the SwitchGear Genomics hypoxia set of promoter reporter assays, differentiated between 3 hypoxia mimetics and 2 other compounds that triggered the pathway independent of HIF-1alpha, a result important for effective compound screening.
In addition to the hypoxia (HIF1a) pathway products, SwitchGear offers the following reporter assay profiling sets in both plate format and biomarker subsets: CREB, NF-kB, heat shock (HSF), p53, STAT, serum response factor (SRF), and cholesterol biosynthesis (SREBP). In addition, the company offers nuclear receptor sets for estrogen receptor, androgen receptor, and glucocorticoid receptor pathways.

SwitchGear Genomics assay-ready 3’UTR constructs establish validity in studies that identify critical functions of microRNAs
Complete panel of 3’UTR reporter assays empowers researchers to quickly and quantitatively measure miRNA impact
MENLO PARK, Calif. – June 5, 2009 – SwitchGear Genomics Inc., a leading provider of products for studying the regulatory elements in the human genome, today announced the application of its UTR Reporter Collection™ product line in uncovering critical miRNA functions in several recent research studies.
A joint team from SwitchGear Genomics and Thermo Fisher Scientific recently published the results of a study that demonstrate key miRNA activity in mesenchymal stem cell differentiation. The study also illustrated the benefits of employing a functional profiling strategy for comprehending complex miRNA pathways.
The findings are published in the article “Functional Profiling Reveals Critical Role for miRNA in Differentiation of Human Mesenchymal Stem Cells” at http://dx.plos.org/10.1371/journal.pone.0005605.
“Current available methods focus on measuring only the levels of miRNAs within a cell type but do not identify the actual roles or targets of these miRNAs,” stated Devin Leake, Director of Research and Development for Thermo Fisher Scientific’s genomics business, which includes the Thermo Scientific Dharmacon line of microRNA products. “We conducted functional analysis of miRNAs and revealed those miRNAs that act as regulators in early hMSC differentiation.”
The team used the SwitchGear Genomics transfection-ready and sequence-verified reporter constructs to quantitatively measure the effects of miRNA mimics of interest on endogenous 3’UTRs.
“Our genome-wide collection of assay-ready 3’UTR constructs enable researchers to quickly measure miRNA function,” said Nathan Trinklein, Ph.D., co-founder and CEO of SwitchGear Genomics, “Researchers can focus on quantifying miRNA activity on transcript regulation and translational efficiency to gain insight into the actual functions of these miRNAs without having to spend time on cloning.”
In another recent article in Cancer Research, “Coordinated regulation of cell cycle transcripts by p53-inducible microRNAs, miR-192 and miR-215,” researchers describe the function of key regulatory cell cycle miRNAs. The SwitchGear reporter constructs provided the key insight that these miRNAs function as tumor suppressors and that multiple miRNA families operate in the p53 network.
Researchers at SwitchGear Genomics further conducted a study on the role of miR-122, an important regulator of cholesterol and fatty-acid metabolism in liver that has been suggested as a therapeutic target for metabolic disease. The study revealed the target UTRs that specifically responded to miR-122 in addition to the genes that it translationally repressed. The complete findings are available at http://switchgeargenomics.com/products/utr-reporter-collection/.

First Ready-To-Screen Libraries Available for High-throughput Regulatory Pathway Research
SwitchGear functional macroarray incorporates Promega luciferase technology
Madison, WI USA (July 24, 2007) Researchers can efficiently screen entire genetic pathways in living cells with new tools developed by SwitchGear Genomics. The product offering, which includes the first ready-to-screen libraries for high-throughput regulatory pathway research, consists of thousands of human promoters, UTRs and other regulatory elements encompassing many different disease-related pathways.
“Our philosophy at SwitchGear Genomics is that conclusions can be made with much higher confidence by integrating the data from multiple independent genome-scale experiments,” explains Shelley Force Aldred, President of SwitchGear Genomics. “These integrated data sets will explain a transcriptional regulatory network in much greater detail than if the data sets were analyzed independently of one another.”
The new tools contain Promega luciferase reporter technology. Specifically, this new offering leverages all the strengths of luciferase reporters in ease and sensitivity to provide insights into cellular signaling events following xenobiotic treatment.
“The Promega luciferase reporters, specifically the luc2P construct, offer the best characteristics in a bioluminescent reporter assay. It really delivers the strongest sensitivity, dynamic range, turnover rate and compatibility with high-throughput platforms,” says Force Aldred.
All of the regulatory elements in the libraries are cloned in a vector containing the luc2P gene, a destabilized luciferase that contains a Pro-Glu-Ser-Thr (PEST) peptide sequence for faster response time and decreased time to maximum induction.
Nathan Trinklein, PhD, CEO of SwitchGear Genomics will present the new technology at:

New Technology to Study the Mechanism of Cancer
Switchgear Genomics unveils new experimental technology to characterize the biological networks of cancer cells.
Menlo Park, CA, April 12, 2007 –(PR.com)– SwitchGear Genomics is a biotech company based on technology developed at Stanford University that focuses on the molecular switches in the human genome that turn genes on and off. The company has just released the world’s first tool to rapidly and accurately interrogate the function of over 3,000 DNA switches that regulate cancer biology. This oncology tool enables researchers to study the activity of regulatory switches in living cancer cells. Richard Myers, Chairman of Genetics Department at Stanford University says, “SwitchGear’s novel platform directly measures the mechanisms that regulate cancer genetics. It is very exciting technology, and our lab plans to use it to provide a deeper understanding of the biology of cancer. We hope that this work will ultimately lead to new and better cancer therapeutics.”
Cancer is a genetic disease characterized by the erroneous processing of information contained in our genome. Billions of dollars have been spent in an effort to identify the genes involved in cancer. However, protein-coding genes make up a small fraction of the total genome and provide a limited view into the causes of cancer. According to Nathan Trinklein, CEO and co-founder of SwitchGear Genomics, “The DNA switches identified by SwitchGear are critical to understanding how information in the genome is processed. Cancer is a very complex disease, but one thing all cancers have in common is the inability of cells to recognize the signals to stop dividing. Many of these growth signals are contained in the DNA switches identified by SwitchGear, and researchers will now be able to analyze their function on a high-throughput scale. Our initial beta customers in pharmaceutical and academic research groups have rapidly generated very interesting data sets.”
