3′-Untranslated region of doublecortin mRNA is a binding target of the Musashi1 RNA-binding protein

AbstractMusashi1 (Msi1) is an RNA-binding protein that is highly expressed in neural stem cells, and is considered to be a stemness factor. A known function of Msi1 is translational repression of specifically bound mRNAs. Although the basic mechanism and some target RNAs have been reported, further survey of interactors is necessary to understand the integrated function of Msi1. By screening using an mRNA display technique, we found that doublecortin (dcx) mRNA is a specific binding target of Msi1 in vitro. We confirmed that Msil repressed translation of a luciferase reporter gene linked to the selected 3′-untranslated region fragment of dcx in Neuro2A cells

Finding a Maximum Weight Independent Set of a Circle Graph

We present an algorithm for finding a maximum weight independent set of a circle graph. For a cicle graph of a set of n chords with N endpoints, the algorithm finds a maximum weight independent set in O(nN) time and O(n) space.Special Section LETTER (Special Issue on Discrete Mathematics and Its Applications

Tailoring coupling of light to local plasmons by using Ag nanorods/structured dielectric/mirror sandwiches

The optical properties of the sandwich of Ag nanorod array (NRA)/structured dielectric layer/Ag mirror have been investigated theoretically and experimentally, where the structured dielectric layer has stacked sublayers of an anisotropic nanocolumnar layer and a uniform layer. The functions of the nanocolumnar and the uniform sublayers are to control shape of the Ag nanorods and to tune optical path length inside the sandwich, respectively. Calculations based on a simple model by treating the NRAs as uniform effective media indicate that the antireflection condition is realized by changing the thickness of the dielectric layer and that the Ag nanorods absorb most of the incident light. The designed structures have been successfully fabricated by taking advantages of the dynamic oblique-angle deposition technique. Under the experimental antireflection condition, Raman scattering measured on the Ag NRA in the near infrared region exhibits significant enhancement. This indicates that the local electric field close to the Ag nanorods can be controlled by the interference of light in the nanostructured sandwiches
