TLDR
Non-coding RNAs seem to be particularly abundant in roles that require highly specific nucleic acid recognition without complex catalysis, such as in directing post-transcriptional regulation of gene expression or in guiding RNA modifications.
Abstract
Non-coding RNA (ncRNA) genes produce functional RNA molecules rather than encoding proteins. However, almost all means of gene identification assume that genes encode proteins, so even in the era of complete genome sequences, ncRNA genes have been effectively invisible. Recently, several different systematic screens have identified a surprisingly large number of new ncRNA genes. Non-coding RNAs seem to be particularly abundant in roles that require highly specific nucleic acid recognition without complex catalysis, such as in directing post-transcriptional regulation of gene expression or in guiding RNA modifications.

Chromatin signature reveals over a thousand highly conserved large non-coding RNAs in mammals

TL;DR: It is demonstrated that specific lincRNAs are transcriptionally regulated by key transcription factors in these processes such as p53, NFκB, Sox2, Oct4 (also known as Pou5f1) and Nanog, defining a unique collection of functional linc RNAs that are highly conserved and implicated in diverse biological processes.

TL;DR: Mutation of an Arabidopsis Dicer homolog, CARPEL FACTORY, prevents the accumulation of miRNAs, showing that similar mechanisms direct miRNA processing in plants and animals.

CPC: assess the protein-coding potential of transcripts using sequence features and support vector machine

TL;DR: A support vector machine-based classifier, named Coding Potential Calculator (CPC), to assess the protein-coding potential of a transcript based on six biologically meaningful sequence features, which can discriminate coding from noncoding transcripts with high accuracy.

Modular regulatory principles of large non-coding RNAs

TL;DR: This work synthesizes studies to provide an emerging model whereby large ncRNAs might achieve regulatory specificity through modularity, assembling diverse combinations of proteins and possibly RNA and DNA interactions.

Modern metabolism as a palimpsest of the RNA world.

TL;DR: An approach is developed for constructing models of ancient organisms using data from metabolic pathways, genetic organization, chemical structure, and enzymatic reaction mechanisms found in contemporary organisms, illustrated by a partial reconstruction of a model for the "breakthrough organism," the last organism to use RNA as the sole genetically encoded biological catalyst.

Computational identification of noncoding RNAs in E. coli by comparative genomics.

TL;DR: A computational comparative genomic screen for ncRNA genes is described, to distinguish conserved RNA secondary structures from a background of other conserved sequences using probabilistic models of expected mutational patterns in pairwise sequence alignments.

Isolation and genetic characterization of cell-lineage mutants of the nematode caenorhabditis elegans

TL;DR: Twenty-four mutants that alter the normally invariant post-embryonic cell lineages of the nematode Caenorhabditis elegans have been isolated and genetically characterized, suggesting that their phenotypes result from the complete absence of gene activity.

RNA expression analysis using a 30 base pair resolution Escherichia coli genome array.

TL;DR: A high-resolution “genome array” for the study of gene expression and regulation in Escherichia coli detected transcripts for 97% and 87% of the ORFs in stationary and log phases, and transcription of between 3,000 and 4,000 predicted ORFs was observed from the antisense strand, indicating that most of the genome is transcribed at a detectable level.

Analysis of expressed sequence tags indicates 35,000 human genes

TL;DR: The number of human genes is estimated by comparing a set of human expressed sequence tag (EST) contigs with human chromosome 22 and with a non-redundant set of mRNA sequences to give mutually consistent estimates of approximately 35,000, substantially lower than most previous estimates.
