The RNA-binding protein LARP1 is a post-transcriptional regulator of survival and tumorigenesis in ovarian cancer [PDF]
, 2015 RNA-binding proteins (RBPs) are increasingly identified as post-transcriptional drivers of cancer progression. The RBP LARP1 is an mRNA stability regulator, and elevated expression of the protein in hepatocellular and lung cancers is correlated with ...

The Kaposi’s sarcoma-associated herpesvirus ORF57 protein and its multiple roles in mRNA biogenesis
Frontiers in Microbiology, 2012 Post-transcriptional events which regulate mRNA biogenesis are fundamental to the control of gene expression. A nascent mRNA is therefore steered through multimeric RNA-protein complexes that mediate its capping, splicing, polyadenylation, nuclear export

Translation Initiation Control of RNase E-Mediated Decay of Polycistronic gal mRNA
Frontiers in Molecular Biosciences, 2020 In bacteria, mRNA decay is a major mechanism for regulating gene expression. In Escherichia coli, mRNA decay initiates with endonucleolytic cleavage by RNase E. Translating ribosomes impede RNase E cleavage, thus providing stability to mRNA.

Ornithine Decarboxylase mRNA is Stabilized in an mTORC1-dependent Manner in Ras-transformed Cells [PDF]
, 2012 Upon Ras activation, ODC (ornithine decarboxylase) is markedly induced, and numerous studies suggest that ODC expression is controlled by Ras effector pathways. ODC is therefore a potential target in the treatment and prevention of Ras-driven tumours. In

Genome-wide profiling of uncapped mRNA [PDF]
, 2012 Gene transcripts are under extensive posttranscriptional regulation, including the regulation of their stability. A major route for mRNA degradation produces uncapped mRNAs, which can be generated by decapping enzymes, endonucleases, and small RNAs ...

Long Non-coding RNAs in the Cytoplasm
Genomics, Proteomics & Bioinformatics, 2016 An enormous amount of long non-coding RNAs (lncRNAs) transcribed from eukaryotic genome are important regulators in different aspects of cellular events. Cytoplasm is the residence and the site of action for many lncRNAs.

Genomic run-on evaluates transcription rates for all yeast genes and identifies gene regulatory mechanisms [PDF]
, 2004 Most studies of eukaryotic gene regulation have been done looking at mature mRNA levels. Nevertheless, the steady-state mRNA level is the result of two opposing factors: transcription rate (TR) and mRNA degradation.

The CAF1-NOT complex of trypanosomes
Frontiers in Genetics, 2014 In African trypanosomes, there is no control of transcription initiation by RNA polymerase II at the level of individual protein-coding genes. Transcription is polycistronic, and individual mRNAs are excised by trans splicing and polyadenylation.

RNA Stability Measurements Using RT-qPCR in Arabidopsis Seedlings
Bio-Protocol, 2020 Steady-state mRNA levels are determined by both the rates of transcription and degradation. Regulation of mRNA stability and/or degradation are key factors that can significantly affect mRNA levels and its biological functions.

The stability of mRNA influences the temporal order of the induction of genes encoding inflammatory molecules [PDF]
, 2009 The inflammatory response plays out over time in a reproducible and organized way after an initiating stimulus. Here we show that genes activated in cultured mouse fibroblasts in response to the cytokine tumor necrosis factor could be categorized into ...
