HepatoNet1b

HepatoNet1 was subjected to additional consistency checks which resulted in the identification of a system of reactions which are not complete and, thus, the respective reactions could not carry a flux. As the reactions described a protein modification in the nucleus, the have been considered beyond the scope of metabolic network and removed. As in liver fibrosis also the hepatocyte excrete collagens, a comprehensive list of collagens have been added as additional macromolecular synthesis functions. This network, caled Hepatonet1b has been used in several projects.

The gene associations to all reactions have been curated in a multi-step process. In the first attempt, the well-known annotations, stored in KEGG database, have automatically been assigned. Then, the remaining reactions have been analyzed with the help of UniProt, BRENDA and Ensemble databases, and further annotations are semi-automatically annotated. Then, homologous enzymes from other mammals (mouse, rat, rabbit, cow) haven been studied to obtain further annotations. Finally, the remaining reactions have been searched for in the scientific literature to assign further genes, or, in most cases confirm, that no gene is associated to the reaction.

This process has also been performed for mouse genes. In fact, no reaction in HepatoNet1 was found, which is not present in human, and vice versa. The network including mouse annotations, called HepatoNet1b_mouse, is deposited in Biomodels database under the identifier MODEL1208060000 .
