Although we can describe complex networks, we cannot easily determine which topology the cell actually uses to transduce a specific signal. Experimental testing of all plausible topologies is infeasible because of the combinatorially large number of experiments required to explore the complete hypothesis space. Here, we demonstrate that Bayesian inference-based modeling provides an approach to explore and constrain this hypothesis space,permitting the rational ranking of pathway models. Our approach can use measurements of a limited number of biochemical species when combined with multiple perturbations. As proof of concept, we examined the activation of the extracellular signal-regulated kinase (ERK) pathway by epidermal growth factor. The predicted and experimentally validated model shows that both Raf-1 and, unexpectedly,B-Raf are needed to fully activate ERK in two different cell lines. Thus, our formal methodology rationally infers evidentially supported pathway topologies even when a limited number of biochemical and kinetic measurements are available.</p>","PeriodicalId":49560,"journal":{"name":"Science Signaling","volume":"3 134","pages":"ra20"},"PeriodicalIF":7.3,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29205816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How can memory traces persist over days or weeks, despite the short-lived nature and rapid turnover of their molecular substrates? It has recently been reported that, in order to persist, an otherwise rapidly forgotten long-term memory requires BDNF (brain-derived neurotrophic factor) expression in the hippocampus 12 hours after training. Rossato et al. now show that this mechanism is gated into action by activation of the ventral tegmental area acting upon dopamine D1 receptors in the hippocampus. Time-limited N-methyl-D-aspartate receptor–dependent activity in the ventral tegmental area–hippocampal circuitry underlies the delayed increase in BDNF levels in the hippocampus 12 hours after inhibitory avoidance, a hippocampus-dependent form of learning.
