    Near-Infrared Phosphors with Persistent Luminescence over 1000 nm for Optical Imaging

    No full text
    Persistent phosphors with “self-sustained” light emission are considered to be one of the most promising candidates for the new-generation “background-free” optical imaging. In particular, near-infrared (NIR) persistent luminescence (PersL) over 1000 nm has demonstrated the superior power to obtain deep penetration depth and high-fidelity imaging due to the avoidance of real-time external excitation. In this chapter, we will give comprehensive insights into the state-of-the-art of NIR (>1000 nm) persistent phosphors, starting from the introduction of basic principles of light-matter interactions, followed by the description of NIR autofluorescence phenomena of bio-tissues and related filtering approaches. Then, the mechanism of PersL, including charge carrier trapping-detrapping phenomena, persistent energy transfer (ET) process, and photostimulation-induced trap redistribution approaches, will be explained to give a general picture of how PersL works and how we can play with the information of energy-level locations of host bands, activators and traps. The reported over 1000-nm NIR-persistent phosphors, basically divided into lanthanide and transition-metal ions-activated ones will be summarized with highlighted examples to introduce design concepts of these phosphors. Finally, we draw a prospective of key challenges and feasible improvements in the future following the current trends of this research field

    Proline-rich tyrosine kinase 2 mediates gonadotropin-releasing hormone signaling to a specific extracellularly regulated kinase-sensitive transcriptional locus in the luteinizing hormone beta-subunit gene

    G protein-coupled receptor regulation of gene transcription primarily occurs through the phosphorylation of transcription factors by MAPKs. This requires transduction of an activating signal via scaffold proteins that can ultimately determine the outcome by binding signaling kinases and adapter proteins with effects on the target transcription factor and locus of activation. By investigating these mechanisms, we have elucidated how pituitary gonadotrope cells decode an input GnRH signal into coherent transcriptional output from the LH beta-subunit gene promoter. We show that GnRH activates c-Src and multiple members of the MAPK family, c-Jun NH2-terminal kinase 1/2, p38MAPK, and ERK1/2. Using dominant-negative point mutations and chemical inhibitors, we identified that calcium-dependent proline-rich tyrosine kinase 2 specifically acts as a scaffold for a focal adhesion/cytoskeleton-dependent complex comprised of c-Src, Grb2, and mSos that translocates an ERK-activating signal to the nucleus. The locus of action of ERK was specifically mapped to early growth response-1 (Egr-1) DNA binding sites within the LH beta-subunit gene proximal promoter, which was also activated by p38MAPK, but not c-Jun NH2-terminal kinase 1/2. Egr-1 was confirmed as the transcription factor target of ERK and p38MAPK by blockade of protein expression, transcriptional activity, and DNA binding. We have identified a novel GnRH-activated proline-rich tyrosine kinase 2-dependent ERK-mediated signal transduction pathway that specifically regulates Egr-1 activation of the LH beta-subunit proximal gene promoter, and thus provide insight into the molecular mechanisms required for differential regulation of gonadotropin gene expression
