By the end of the first week in culture, hippocampal neurons have established a single axon
and several dendrites. These 2 classes of processes differ in their morphology, in their …

In plants, microRNAs (miRNAs) comprise one of two classes of small RNAs that function
primarily as negative regulators at the posttranscriptional level. Several MIRNA genes in the …

Deregulation of micro-RNAs (miRNAs) is emerging as a major aspect of cancer etiology
because their capacity to direct the translation and stability of targeted transcripts can …

MicroRNAs (miRNAs) are small (∼ 22-nucleotide) RNAs that in lower organisms serve
important regulatory roles in development and gene expression, typically by forming imperfect …

Eukaryotes contain a diversified set of small RNA-guided pathways that control genes,
repeated sequences, and viruses at the transcriptional and posttranscriptional levels. Genome-…

Megalencephaly-capillary malformation (MCAP) and megalencephaly-polymicrogyria-polydactyly-hydrocephalus
(MPPH) syndromes are sporadic overgrowth disorders associated …

Correct daily phasing of transcription confers an adaptive advantage to almost all organisms,
including higher plants. In this study, we describe a hypothesis-driven network discovery …

We have developed an approach to identify microRNAs (miRNAs) that is based on
bioinformatics and array-based technologies, without the use of cDNA cloning. The approach, …

Plants respond to virus infections by activation of RNA-based silencing, which limits infection
at both the single-cell and system levels. Viruses encode RNA silencing suppressor …

MicroRNAs (miRNAs) are the subject of enormous interest. They are small non-coding RNAs
that play a regulatory role in numerous and diverse cellular processes such as immune …
