Context-dependent transcriptional regulations between signal transduction pathways

Modeling signal transduction pathways and their transcriptional response

Engineering Signal Transduction Pathways

Cells respond to their environment by sensing signals and translating them into changes in gene expression. In recent years, synthetic networks have been designed in both prokaryotic and eukaryotic systems to create new functionalities and for specific applications. In this review, we discuss the challenges associated with engineering signal transduction pathways. Furthermore, we address advant...

Transcriptional crosstalk between nuclear receptors and cytokine signal transduction pathways in immunity.

The nuclear receptor superfamily and the transcriptional factors associated with cytokines are inherently different families of signaling molecules and activate gene transcription by binding to their respective responsive element. However, it has become increasingly clear from our works and others that nuclear receptors are important regulators of cytokine production and function through comple...

G-protein-dependent and -independent pathways in denatonium signal transduction.

To clarify the involvement of G protein in denatonium signal transduction, we carried out a whole-cell patch-clamp analysis with isolated taste cells in mice. Two different responses were observed by applying GDP-beta-S, a G-protein inhibitor. One response to denatonium was reduced by GDP-beta-S (G-protein-dependent), whereas the other was not affected (G-protein-independent). These different p...

Signal Transduction Pathways for Leptin

Leptin is a critical regulator of energy balance in mammals and has served as a launch point for innumerable studies examining the regulation of food intake and energy expenditure (1). At high physiological concentrations, leptin causes a decrease in food intake, an increase in energy expenditure, and a shift to increased fatty acid oxidation. These physiological shifts lead to a decrease in bo...
