We examined whether the cAMP-response element binding protein (CREB), a transcription factor that mediates cytokine expression and vascular remodeling, is involved in TNFα-induced VCAM-1 expression.

Typically, transcription factors are modular proteins that regulate the expression of genes through their binding to DNA regulatory elements. They can either activate or repress the transcription ...

The factors used to induce pluripotency and create so-called adult stem cells are anything but inert, but they could use extra “oomph.” To enhance their effect, say scientist in France ...

Figure 13: Comparison of S 22 for three different lumped element models of a 131 MHz lumped element LC low-pass filter. It can be seen that the expanded capacitor and inductor models yield more ...
