Neuronal development and plasticity are maintained by tightly regulated gene expression programs. Here, we report that the developmentally regulated microRNA miR-375 affects dendrite formation and maintenance. miR-375 overexpression in mouse hippocampus potently reduced dendrite density. We identified the predominantly neuronal RNA-binding protein HuD as a(More)
OBJECTIVE Anxiety and depressive mood are sometimes accompanied by modulation of neuroendocrine and immune functions. The aim of this study was to identify circulating immune mediators reflecting anxiety and depressive mood in healthy young adults. METHODS Anxiety and depressive mood in 209 healthy medical students (125 males and 84 females, aged(More)
Non-coding microRNAs (miRNAs) are suggested to serve fundamental roles in cellular stress responses and in coping with sudden environmental changes in experimental animals. We examined whether naturalistic stressor-responsive miRNAs were detectable in whole blood. Blood and saliva were collected between 16:00 and 17:00 from 10 healthy medical students (5(More)
In cells responding to low oxygen levels, gene expression patterns are strongly influenced by post-transcriptional processes. RNA-binding proteins (RBPs) are pivotal regulators of gene expression in response to numerous stresses, including hypoxia. Here, we review the RBPs that modulate mRNA turnover and translation in response to hypoxic challenge. The(More)
To assess response to chronic psychological stress, gene expression profiles in peripheral blood from 18 medical students confronting license examination were analyzed using an original microarray. Total RNA was collected from each subject 9 months before the examination and mixed to be used as a universal control. At that time, most students had normal(More)
Vascular endothelial growth factor-a (VEGF)-targeted therapies have become an important treatment for a number of human malignancies. The VEGF inhibitors are actually effective in several types of cancers, however, the benefits are transiently, and the vast majority of patients who initially respond to the therapies will develop resistance. One of possible(More)
Gene expression patterns vary dramatically in a tissue-specific and age-dependent manner. RNA-binding proteins that regulate mRNA turnover and/or translation (TTR-RBPs) critically affect the subsets of expressed proteins. Although many proteins implicated in age-related processes are encoded by mRNAs that are targets of TTR-RBPs, very little is known(More)
Gene expression patterns vary dramatically in a tissue-specific and age-dependent manner. RNA-binding proteins that regulate mRNA turnover and/or translation (TTR-RBPs) critically affect the subsets of expressed proteins. However, very little is known regarding the tissue- and age-dependent expression of TTR-RBPs in humans. Here, we use human tissue arrays(More)
BACKGROUND Vascular endothelial growth factor-A (VEGF) is one of the key regulators of tumor development, hence it is considered to be an important therapeutic target for cancer treatment. However, clinical trials have suggested that anti-VEGF monotherapy was less effective than standard chemotherapy. On the basis of the evidence, we hypothesized that vegf(More)
MicroRNAs (miRNAs) play key roles in regulation of cellular processes in response to changes in environment. In this study, we examined alterations in miRNA profiles in peripheral blood from 25 male medical students two months and two days before the National Examination for Medical Practitioners. Blood obtained one month after the examination were used as(More)
