mTOR, translation initiation and cancer [PDF]

Oncogene, 2006
Control of mRNA translation plays a fundamental role in many aspects of cell metabolism. It constitutes a critical step in the control of gene expression, and consequently cell growth, proliferation and differentiation. Translation is regulated in response to nutrient availability, hormones, mitogenic and growth factor stimulation and is coupled with ...

Experimental characterization of Cis-acting elements important for translation and transcription in Halophilic Archaea [PDF]

, 2007
Summary The basal transcription apparatus of archaea is well characterized. However, much less is known about the mechanisms of transcription termination and translation initation.

Cell cycle progression or translation control is not essential for vesicular stomatitis virus oncolysis of hepatocellular carcinoma. [PDF]

, 2010
The intrinsic oncolytic specificity of vesicular stomatitis virus (VSV) is currently being exploited to develop alternative therapeutic strategies for hepatocellular carcinoma (HCC). Identifying key regulators in diverse transduction pathways that define

Local absence of secondary structure permits translation of mRNAs that lack ribosome-binding sites. [PDF]

PLoS Genetics, 2011
The initiation of translation is a fundamental and highly regulated process in gene expression. Translation initiation in prokaryotic systems usually requires interaction between the ribosome and an mRNA sequence upstream of the initiation codon, the so ...

Cellular mRNAs access second ORFs using a novel amino acid sequence-dependent coupled translation termination-reinitiation mechanism [PDF]

, 2014
Polycistronic transcripts are considered rare in the human genome. Initiation of translation of internal ORFs of eukaryotic genes has been shown to use either leaky scanning or highly structured IRES regions to access initiation codons.

Noncanonical Translation Initiation in Eukaryotes [PDF]

Cold Spring Harbor Perspectives in Biology, 2018
The vast majority of eukaryotic messenger RNAs (mRNAs) initiate translation through a canonical, cap-dependent mechanism requiring a free 5' end and 5' cap and several initiation factors to form a translationally active ribosome. Stresses such as hypoxia, apoptosis, starvation, and viral infection down-regulate cap-dependent translation during which ...

A var gene upstream element controls protein synthesis at the level of translation initiation in Plasmodium falciparum [PDF]

, 2013
Clonally variant protein expression in the malaria parasite Plasmodium falciparum generates phenotypic variability and allows isogenic populations to adapt to environmental changes encountered during blood stage infection.

The role of cellular signalling pathways and translation initiation factors in Herpesvirus infection [PDF]

, 2011
As obligate intracellular parasites, viruses rely on host cells to replicate. Hsv-1 is a large double stranded DNA virus which is the cause of common cold sores and corneal blindness in humans. The defining feature of HSV-1 is its ability to exist in two

Synonymous codon usage regulates translation initiation

Cell Reports, 2023
Summary: Nonoptimal synonymous codons repress gene expression, but the underlying mechanisms are poorly understood. We and others have previously shown that nonoptimal codons slow translation elongation speeds and thereby trigger messenger RNA (mRNA ...

Comparison of computational methods for identifying translation initiation sites in EST data

BMC Bioinformatics, 2004
Background Expressed Sequence Tag (EST) sequences are generally single-strand, single-pass sequences, only 200–600 nucleotides long, contain errors resulting in frame shifts, and represent different parts of their parent cDNA.
