Project description:Hoppe2012 - Predicting changes in metabolic function using transcript profiles
Measuring metabolite concentrations, reaction fluxes, and enzyme activities on large scale are tricky tasks in the study of cellular metabolism. Here, a method that predicts activity changes of metabolic functions based on relative transcript profiles, has been presented. It provides a ranked list of most regulated functions. The method has been applied to TGF-beta treatment of hepatocyte cultures. This stoichiometric model of the mouse hepatocyte is based on a corrected and extended version of HepatoNet1.
This model is described in the article:
ModeScore: A Method to Infer Changed Activity of Metabolic Function from Transcript Profiles
Andreas Hoppe and Hermann-Georg Holzhütter
German Conference on Bioinformatics 2012; Publ.13.09.2012
Abstract:
Genome-wide transcript profiles are often the only available quantitative data for a particular
perturbation of a cellular system and their interpretation with respect to the metabolism is a
major challenge in systems biology, especially beyond on/off distinction of genes.
We present a method that predicts activity changes of metabolic functions by scoring reference
flux distributions based on relative transcript profiles, providing a ranked list of most regulated
functions. Then, for each metabolic function, the involved genes are ranked upon how much they
represent a specific regulation pattern. Compared with the naïve pathway-based approach, the
reference modes can be chosen freely, and they represent full metabolic functions, thus, directly
provide testable hypotheses for the metabolic study.
In conclusion, the novel method provides promising functions for subsequent experimental
elucidation together with outstanding associated genes, solely based on transcript profiles.

Project description:The Norway rat has important impacts on our life. They are amongst the most used research subjects, resulting in ground-breaking advances. At the same time, wild rats live in close association with us, leading to various adverse interactions. In face of this relevance, it is surprising how little is known about their natural behaviour. While recent laboratory studies revealed their complex social skills, little is known about their social behaviour in the wild. An integration of these different scientific approaches is crucial to understand their social life, which will enable us to design more valid research paradigms, develop more effective management strategies, and to provide better welfare standards. Hence, I first summarise the literature on their natural social behaviour. Second, I provide an overview of recent developments concerning their social cognition. Third, I illustrate why an integration of these areas would be beneficial to optimise our interactions with them.

Project description:BackgroundMurine kobuviruses (MuKV) are newly recognized picornaviruses first detected in murine rodents in the USA in 2011. Little information on MuKV epidemiology in murine rodents is available. Therefore, we conducted a survey of the prevalence and genomic characteristics of rat kobuvirus in Guangdong, China.ResultsFecal samples from 223 rats (Rattus norvegicus) were collected from Guangdong and kobuviruses were detected in 12.6% (28) of samples. Phylogenetic analysis based on partial 3D and complete VP1 sequence regions showed that rat kobuvirus obtained in this study were genetically closely related to those of rat/mouse kobuvirus reported in other geographical areas. Two near full-length rat kobuvirus genomes (MM33, GZ85) were acquired and phylogenetic analysis of these revealed that they shared very high nucleotide/amino acids identity with one another (95.4%/99.4%) and a sewage-derived sequence (86.9%/93.5% and 87.5%/93.7%, respectively). Comparison with original Aichivirus A strains, such human kobuvirus, revealed amino acid identity values of approximately 80%.ConclusionOur findings indicate that rat kobuvirus have distinctive genetic characteristics from other Aichivirus A viruses. Additionally, rat kobuvirus may spread via sewage.
