Project description:Imatinib mesylate (IM) a protein kinase inhibitor drug that selectively inhibits certain oncogenic mutant protein tyrosine kinases. After application, IM is via hospital and municipal waste water effluents released into the aquatic environment, where it can harm non-target organisms. The aim of this study was to evaluate changes in gene transcription in liver of adult F1 zebrafish (Danio rerio) continuously exposed to IM at environmentaly relevant concentrations of 0.01 µg/L and 1 µg/L.

Project description:The fluoropyrimidine 5-fluorouracil (5-FU) is an antimetabolite that exerts its anticancer effects through inhibition of DNA synthesis and replication by inhibiting thymidylate synthase, and by incorporation of its metabolites into RNA and DNA. 5-FU is used in most of the currently applied regimens for the treatment of patients with cancers of the gastrointestinal tract, breast, head, neck, and belongs to the most consumed cytostatic drugs. After application, 5-FU is via hospital and municipal waste water effluents released into the aquatic environment, where it can harm non-target organisms. The aim of this study was to evaluate changes in gene transcription in liver of adult F1 zebrafish (Danio rerio) continuously exposed to 5-FU at environmentaly relevant concentrations of 0.01 µg/L and 1 µg/L.

Abstract:
The rumen represents the first section of a ruminant
animal's stomach, where feed is collected and mixed with
microorganisms for initial digestion. The major gas produced in
the rumen is CO(2) (65.5 mol%), yet the metabolic
characteristics of capnophilic (CO(2)-loving) microorganisms
are not well understood. Here we report the 2,314,078 base pair
genome sequence of Mannheimia succiniciproducens MBEL55E, a
recently isolated capnophilic Gram-negative bacterium from
bovine rumen, and analyze its genome contents and metabolic
characteristics. The metabolism of M. succiniciproducens was
found to be well adapted to the oxygen-free rumen by using
fumarate as a major electron acceptor. Genome-scale metabolic
flux analysis indicated that CO(2) is important for the
carboxylation of phosphoenolpyruvate to oxaloacetate, which is
converted to succinic acid by the reductive tricarboxylic acid
cycle and menaquinone systems. This characteristic metabolism
allows highly efficient production of succinic acid, an
important four-carbon industrial chemical.
