Long-range transcriptional interference in E. coli used to construct a dual positive selection system for genetic switches

We have investigated transcriptional interference between convergent genes in E. coli and demonstrate substantial interference for inter-promoter distances of as far as 3 kb. Interference can be elicited by both strong σ(70) dependent and T7 promoters. In the presented design, a strong promoter driving gene expression of a 'forward' gene interferes with the expression of a 'reverse' gene by a w...

Evidence for transcriptional interference in a dual-luciferase reporter system.

The dual-luciferase reporter assay is widely used for microRNA target identification and the functional validation of predicted targets. To determine whether curcumin regulates expression of the histone methyltransferase enhancer of zeste homolog 2 (EZH2) by targeting its 3'untranslated region (3'UTR), two luciferase reporter systems containing exactly the same sequence of the EZH2 3'UTR were u...

Attentional Switches and Dual-Task Interference

In four experiments, we studied the time course of interference between detection of an oddball orientation target (OT) in an 8-item circular search display, and identification of a letter target (LT) in a central stream of distractor letters. Dual-task performance for different temporal lags between targets was compared to single-task performance. When the LT preceded the OT, dual-task perform...

Modeling genetic switches with positive feedback loops.

In this paper, we develop a new methodology to design synthetic genetic switch networks with multiple genes and time delays, by using monotone dynamical systems. We show that the networks with only positive feedback loops have no stable oscillation but stable equilibria whose stability is independent of the time delays. In other words, such systems have ideal properties for switch networks and ...

Construction of T-vector derived from pBluescript ΙΙ SK with a positive selection marker, a rapid system for cloning

A rapid DNA cloning system is a research interest of many scientists. TA cloning is one of the methods used for the cloning of PCR-amplified DNA molecules. The TA cloning method is a convenient and labor-saving replacement to traditional, restriction enzyme-mediated cloning strategies. A T-vector called pBlueskript ΙΙ SK-1 with the lethal gene ccdB was designed to construct a positive selection...
