The 5'UTR Intron of Arabidopsis GGT1 Aminotransferase Enhances Promoter Activity by Recruiting RNA Polymerase II.

Photorespiration is essential for the detoxification of glycolate and recycling of carbon to the Calvin Benson Bassham cycle. Enzymes participating in the pathway have been identified, and investigations now focus on the regulation of photorespiration by transporters and metabolites. However, regulation of photorespiration on the gene level has not been intensively studied.

Reboxetine in a neuroendocrine challenge paradigm: evidence for high cortisol responses in healthy volunteers scoring high on subclinical depression.

This paper investigates if the highly selective norepinephrine reuptake inhibitor reboxetine leads to a dose-dependent cortisol release and if this response depends on personality dimensions related to clinical depression in healthy volunteers. Twenty-four male subjects received placebo, 2 mg, or 4 mg reboxetine in a balanced, randomized cross-over study. Cortisol was measured in saliva at six different time-points according to the kinetics of the drug.
