Delivery remains one of the last barriers for applying RNA interference (RNAi) in clinically relevant cell lines. Investigations at Dharmacon have led to the development of an innovative molecule for delivery in a wide variety of cell types. These modified siRNAs have been found to effectively silence target genes in cell types that are typically difficult to transfect using standard delivery methods. We present data for multiple cell types including SH-SY5Y (neuroblastoma), Jurkat (T-cells), and primary neurons. This technology, Dharmacon™ Accell™ siRNA reagents, allows for functional genomic studies in pertinent cell types. Moreover, in some instances, cells can be continuously dosed with these siRNAs, thus enabling knockdown of any target gene of interest for extended durations.
P450 Induction in Cryopreserved Hepatocytes from PXR and CAR Nuclear Receptor Knock-out RatsPoster
The nuclear receptors pregnane X receptor (PXR) and constitutive androstane receptor (CAR) are closely related transcription factors that regulate the expression of phase I (cytochrome P450s), phase II metabolizing enzymes and transporter genes in response to xenobiotics, including prescription drugs.READ MORE
Psychiatric Risk Gene Cacna1c and Early Life Stress: Potential Gene-Environment interactions?Poster
Early life stress (ELS) is highly associated with development of psychopathology
and mood disorders in adulthood. Genetic studies have identified variation in the gene calcium voltage-gated channel subunit alpha1C (CACNA1C) to increase risk for several psychiatric disorders. This poster assessed the expression of Cacna1c following prepubertal stress.
Novel Role of the Innate Immune DNA Sensor IFI16 (Interferon Gamma Inducible Protein 16) as a Major Epigenetic Modulator During KSHV Infection and Lytic ReactivationPoster
Studies have shown that IFI16 acts as an antiviral restriction factor against a number of DNA viruses, by inhibiting viral replication or transcription through epigenetic modifications. However, till date, no specific epigenetic function of IFI16 has been identified. Here, we have discovered that IFI16 recruits two histone methyltransferases on the KSHV episome leading to altered Histone H3K9 methylation, thus regulating its lifecycle.READ MORE
