As an initial step towards understanding the molecular mechanisms by which plants become invasive, we present here the first transcriptome analysis for an invasive weed Mikania micrantha. The analysis was based on the 75-nucleotide short reads data generated by the Illumina Genome Analyzer II system. A total of 31 131 unique sequences were assembled de novo… (More)
c-MYC is an important oncogene that is considered as an effective target for anticancer therapy. Regulation of this gene's transcription is one avenue for c-MYC-targeting drug design. Direct binding to a transcription factor and generating the intervention of a transcriptional programme appears to be an effective way to modulate gene transcription. NM23-H2… (More)
A dicyanoisophorone-based probe with two-photon absorption and NIR emission was developed for the in vivo fluorescence imaging of amyloid-β plaques, which exhibited high selectivity toward Aβ aggregates over other intracellular proteins. The detection limit was calculated to be as low as 109 nM. In vivo imaging studies indicated that the probe could… (More)
Target-guided synthesis is an approach to drug discovery that allows the target to self-assemble its own binding agents. So far, target-guided synthesis and especially in situ click chemistry have attracted extensive attention and have led to the identification of highly potent inhibitors for proteins. In this study, we expand the application of in situ… (More)
A novel 2,4,5-triaryl-substituted imidazole (IZCM-1) has been found to display distinct and specific fluorescence enhancement upon binding to parallel G-quadruplexes. Such a sensitive and topology-specific probe is able to light up without affecting the topology or thermal stability of the G-quadruplex sample. Thus, these advantages distinguish IZCM-1 from… (More)
A tailor-made colorimetric and red-emitting fluorescent dual probe for G-quadruplex nucleic acids was developed by incorporating a coumarin-hemicyanine fluorophore into an isaindigotone framework. The significant and distinct changes in both the color and fluorescence of this probe enable the label-free and visual detection of G-quadruplex structures.
G-quadruplexes are higher-order DNA and RNA structures formed from guanine-rich sequences. These structures have recently emerged as a new class of potential molecular targets for anticancer drugs. An understanding of the three-dimensional interactions between small molecular ligands and their G-quadruplex targets in solution is crucial for rational drug… (More)
