摘要:
Gene panels, microarrays and biomarker panels relating to genes and gene products associated with age-related oxidative damage to skin, and transcriptional profiling-based methods for identification and evaluation of cosmetic agents for prevention, reversal, or reduction of oxidative damage to skin. Cosmetic agents and compositions comprising the cosmetic agents, capable of inducing nrf2-mediated activation of the antioxidant response element to increase expression of Phase 2 enzymes, methods for restoring optimal redox status to skin employing the agents, and methods for identifying and evaluating cosmetic agents acting via the nrf2-mediated mechanism.
摘要:
Die Erfindung betrifft ein Analyseverfahren zur Bestimmung eines Organfunktionsparameters eines menschlichen oder tierischen Individuums durch Messung des 13 CO 2 -Gehalts in der Ausatemluft des Individuums. Dabei ist der Organfunktionsparameter die Leberfunktionskapazität und/oder die Mikrozirkulation eines Substrates in der Leber, wobei die Leberfunktionskapazität durch Bestimmung der maximalen Umsatzgeschwindigkeit des Substrats im Körper des Individuums ermittelt wird und wobei die Mikrozirkulation durch Bestimmung der Anflutungszeit ermittelt wird. Die Anflutungszeit ist die Zeit zum Erreichen der maximalen Umsatzgeschwindigkeit t vmax des Substrates. Die maximale Umsatzgeschwindigkeit des Substrats im Körper des Individuums wird mittels einer Enzymkinetik nullter Ordnung durch eine Veränderung des gemessenen 13 CO 2 -Gehalts in der Ausatemluft des Individuums bestimmt wird. Die maximale Umsatzgeschwindigkeit und/oder die Anflutungszeit werden mittels einer Division durch das Körpergewicht auf das Körpergewicht des Individuums normiert.
摘要:
The invention is concerned with methods of assaying the activity of enzymes based on measurement of fluorescence lifetime (FLT). In particular, the invention relates to assays for enzymes which are capable of modifying the structure of peptide substrates, including for example enzymes catalysing methylation, demethylation, acetylation, deacetylation or deimination of peptide substrates.

摘要:
A novel class of hydroxylases is described having the amino acid sequence of SEQ ID NO: 2, 4, 6 and 8, and variants and fragments thereof having HIF hydroxylation activity. The polypeptides of the invention have in particular prolyl hydroxylase activity. An assay method monitors the interaction of the HIF hydroxylase with a substrate. Modulators of HIF hydroxylase are provided for use in the treatment of a condition associated with increased or decreased HIF levels or activity or for the treatment of a condition where it is desirable to modulate HIF levels or activity.
