The amygdala is a brain structure considered a key node for the regulation of neuroendocrine stress response. Stress-induced response in amygdala is accomplished through neurotransmitter activation and an alteration of gene expression. MicroRNAs (miRNAs) are important regulators of gene expression in the nervous system and are very well suited effectors of(More)
BACKGROUND Histone demethylases (HDMs) have a prominent role in epigenetic regulation and are emerging as potential therapeutic cancer targets. The search for small molecules able to inhibit HDMs in vivo is very active but at the present few compounds were found to be specific for defined classes of these enzymes. METHODOLOGY/PRINCIPAL FINDINGS In order(More)
The synthesis of core histone variants and of histone H1 variants was determined in fresh leukemic cells of eight patients with leukemia [seven acute lymphoblastic (ALL) and one chronic lymphocytic (CLL)], in normal lymphocytes from healthy donors or from ALL patients in complete remission. Histone variant synthesis was evaluated by incubating cells with(More)
MicroRNAs are endogenous, noncoding RNAs crucial for the post-transcriptional regulation of gene expression. Their role in spatial memory formation, however, is poorly explored. In this study, we analyzed learning-induced microRNA expression in the hippocampus and in the ventral striatum. Among miRNAs specifically downregulated by spatial training, we(More)
MicroRNAs are endogenous, noncoding RNAs crucial for the post-transcriptional regulation of gene expression. In this study, we investigated the role of miR-335-5p in spatial learning and synaptic plasticity. To this end we first showed spatial learning induced down-regulation of miR-335-5p. Next we found impairment in long-term memory and reduction in(More)
