DESCRIPTION

• Notes: Biosafety: The lentiviruses are produced with the SIN (self-inactivation) lentivector which ensures self-inactivation of the lentiviral construct after transduction and after integration into the genomic DNA of the target cells. None of the HIV genes (gag, pol, rev) will be expressed in the transduced cells, as they are expressed from packaging plasmids lacking the packing signal and are not present in the lentivirus particle. Although the pseudotyped lentiviruses are replication-incompetent, they require the use of a Biosafety Level 2 facility. BPS Bioscience recommends following all local federal, state, and institutional regulations and using all appropriate safety precautions.

• Background: GAL4/UAS is a binary gene expression system used for modeling expression vectors or transgenic animals with GAL4 and UAS constructs. UAS is a regulatory sequence critical to induction and the increased expression of a nearby gene of interest. GAL4 binds to UAS to activate transcription from a basal promoter located downstream of the activation sequence. Gal4/UAS is a highly advantageous system that can induce gene expression at a desired time and at higher levels than endogenous tissue-specific promoters. It can link a portion of a nuclear receptor to a reporter system to study ligand binding or to screen small molecules. GAL4 DBD-GR lentivirus (BPS Bioscience #78632), expresses a fusion protein where the glucocorticoid receptor (GR) ligand binding domain is fused to the DNA binding domain of GAL4 (GAL4 DBD). After co-transduction of UAS luciferase reporter lentivirus and GAL4 DBD-GR lentivirus. The glucocorticoid-induced activation of the glucocorticoid receptor can be monitored by measuring the luciferase activity. The glucocorticoid signaling pathway plays an important role in development, fluid homeostasis, cognition, immune response and metabolism. Glucocorticoids are a class of steroid hormones that bind to the glucocorticoid receptor, causing it to translocate to the nucleus. Upon translocation, the receptor can regulate the transcription of many genes, including those that regulate glucose metabolism and inflammatory responses.
• Description: The UAS (Upstream Activation Sequence) Luciferase Reporter Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce almost all types of mammalian cells, including primary and non-dividing cells. The particles contain a firefly luciferase gene driven by a multimerized GAL4 upstream activation sequence (UAS) located upstream of the minimal TATA promoter and an antibiotic selection gene (puromycin) for the selection of stable clones. After transduction, the UAS-controlled signaling pathway in the target cells can be monitored by measuring the luciferase activity.
