Three phases in the evolution of the standard genetic code: how translation could get started [PDF]

open access: yes, 2007
A primordial genetic code is proposed, having only four codons assigned, GGC meaning glycine, GAC meaning aspartate/glutamate, GCC meaning alanine-like and GUC meaning valine-like.

Moderate increase of MET in hepatocytes protects against cholestatic liver injury by promoting an effective antioxidant response

open access: yesThe FEBS Journal, EarlyView.
Moderate overexpression of wild‐type Met in hepatocytes (Alb‐R26Met mouse model) boosts a strong antioxidant response dependent on the glutathione system while impairing TGF‐β signaling in the liver. This leads to improved liver regeneration and protects against DDC‐induced injury, a model for cholestatic disease sharing features with primary ...

Crystal structure of plant γ‐glutamyl peptidase 1: implications for sulfur metabolism and secondary metabolite biosynthesis

open access: yesThe FEBS Journal, EarlyView.
The crystal structures of Arabidopsis thaliana γ‐glutamyl peptidase 1 (GGP1), including the covalent intermediate state, were determined. GGP1 is involved in both glutathione degradation in the primary metabolism and glutathione conjugate processing in the secondary metabolism of glucosinolate and camalexin biosynthesis.

Glutamine Synthetase Activity in Rat Epididymis

open access: yesExperimental Biology and Medicine, 1994
Glutamine synthetase (GS) activity was measured in the caput and cauda regions of rat epididymis. Specific GS activity in the caput was 27-fold higher than that in the cauda. To compare GS activity within the epididymis to that within other tissues, specific and total GS activities were measured in the brain, liver, testes, kidney, and striated muscle.

LAT1/SLC7A5‐mediated amino acid uptake is regulated by redox signals triggered by formyl‐peptide receptor 2

open access: yesThe FEBS Journal, EarlyView.
FPR2 activation mediates NOX‐dependent LAT1 expression and, in turn, promotes mTORC1 signaling. Upon stimulation with WKYMVm, the FPR2‐NOX2‐ROS axis upregulates LAT1 via increased c‐Myc phosphorylation and decreased miR‐126. Additionally, it promotes CD98 translocation to the plasma membrane.

ZBED4, a cone and Müller cell protein in human retina, has a different cellular expression in mouse. [PDF]

open access: yes, 2011
PurposeZBED4, a protein in cones and Müller cells of human retina, may play important functions as a transcriptional activator of genes expressed in those cells or as a co-activator/repressor of their nuclear hormone receptors.

Energetic stress in combination with impaired fatty acid oxidation induces sequestration of CoA and adaptation of CoA metabolism

open access: yesThe FEBS Journal, EarlyView.
Computational modelling and in vitro liver cell experiments indicate that medium‐chain acyl‐CoA dehydrogenase (MCAD) deficiency causes an accumulation of (especially medium‐chain) acyl‐CoAs at the cost of free CoA (CoASH). A substantial decrease in CoASH impairs flux through many pathways essential for energy homeostasis.

B‐GATA factors are required for nitrogen‐responsive growth in Physcomitrium patens and Arabidopsis thaliana

open access: yesNew Phytologist, EarlyView.
Summary We hypothesized that B‐GATA family transcription factors have important roles in growth regulation in moss. We analyzed B‐GATA family transcription factor mutants from Physcomitrium patens and Arabidopsis thaliana to assess growth, gene expression, and cytokinin‐related processes under varying nitrogen conditions.
