Tissue Specific Expression Levels of Apoptosis Involved Genes Have Correlations with Codon and Amino Acid Usage [PDF]
Different mechanisms, including transcriptional and post transcriptional processes, regulate tissue specific expression of genes. In this study, we report differences in gene/protein compositional features between apoptosis involved genes selectively ...

Codon adaptation index as a measure of dominating codon bias [PDF]
Abstract We propose a simple algorithm to detect dominating synonymous codon usage bias in genomes. The algorithm is based on a precise mathematical formulation of the problem that lead us to use the Codon Adaptation Index (CAI) as a ‘universal’ measure of codon bias.

Evolution: are the monkeys’ typewriters rigged? [PDF]
Evolution is presumed to proceed by random mutations, which increase an individual’s fitness. Increased fitness produces a higher survival rate for those individuals within populations and drives the variants to fixation over large timescales to produce ...

Solid Phase Assembly of Fully Protected Trinucleotide Building Blocks for Codon-Based Gene Synthesis
The use of pre-formed trinucleotides, representing codons of the 20 canonical amino acids, for oligonucleotide-directed mutagenesis offers the advantage of controlled randomization and generation of “smart libraries”. We here present a method

Characterization of the mIF4G Domains in the RNA Surveillance Protein Upf2p
Thirty percent of all mutations causing human disease generate mRNAs with premature termination codons (PTCs). Recognition and degradation of these PTC-containing mRNAs is carried out by the mechanism known as nonsense-mediated mRNA decay (NMD).

Converting nonsense codons into sense codons by targeted pseudouridylation [PDF]
All three translation termination codons, or nonsense codons, contain a uridine residue at the first position of the codon. Here, we demonstrate that pseudouridylation (conversion of uridine into pseudouridine (Ψ), ref. 4) of nonsense codons suppresses translation termination both in vitro and in vivo.

A modular and optimized single marker system for generating Trypanosoma brucei cell lines expressing T7 RNA polymerase and the tetracycline repressor [PDF]
Here, we present a simple modular extendable vector system for introducing the T7 RNA polymerase and tetracycline repressor genes into Trypanosoma brucei.

A Novel Mutation of PARK-2 Gene in a Patient with Early-onset Parkinson’s Disease
Between 3–5% of all patients with Parkinson’s disease (PD) have onset before the age of 40 years, which is likely related to genetic causes. Parkin gene mutations are the most common mutations, which are associated with autosomal recessive early-onset PD.

Bacterial oxidative stress responses are generally controlled by transcription factors that modulate the synthesis of RNAs with the aid of some sRNAs that control the stability, and in some cases the translation, of specific mRNAs.

Background Translation dysregulation plays a crucial role in tumourigenesis and cancer progression. Oncogenic translation relies on the stability and availability of tRNAs for protein synthesis, making them potential targets for cancer therapy.
