Oligodendrocyte progenitors originate near the floor plate of the spinal cord, then proliferate and migrate throughout the cord before giving rise to oligodendrocytes. Progenitor cell proliferation stops before birth because the cell cycle slows down, linked to an increase in differentiation and death. Experiments with transgenic mice show that(More)

Fibroblast growth factors (FGFs) act as signals in the developing limb and can maintain proliferation of limb bud mesenchyme cells. Remarkably, beads soaked in FGF-1, FGF-2, or FGF-4 and placed in the presumptive flank of chick embryos induce formation of ectopic limb buds, which can develop into complete limbs. The entire flank can produce additional(More)

The transmembrane receptor 'ROR2' resembles members of the receptor tyrosine kinase family of signalling receptors in sequence but its' signal transduction mechanisms remain enigmatic. This problem has particular importance because mutations in ROR2 are associated with two human skeletal dysmorphology syndromes, recessive Robinow Syndrome (RS) and dominant(More)

A mouse platelet-derived growth factor A chain (PDGF-A) null allele is shown to be homozygous lethal, with two distinct restriction points, one prenatally before E10 and one postnatally. Postnatally surviving PDGF-A-deficient mice develop lung emphysema secondary to the failure of alveolar septation. This is apparently caused by the loss of alveolar(More)
Fibroblast growth factors were first characterized twenty years ago as mitogens of cultured fibroblasts. Despite a wealth of data from experiments in vitro, insights have begun to emerge only recently on the normal function of these growth factors in mice and humans, as a result of studies of natural and experimental mutations in the factors and their(More)
BACKGROUND Appropriately formulated quantitative computational models can support researchers in understanding the dynamic behaviour of biological pathways and support hypothesis formulation and selection by "in silico" experimentation. An obstacle to widespread adoption of this approach is the requirement to formulate a biological pathway as machine(More)
In this work we present a Bio-PEPA model describing the Nuclear Factor κB (NF-κB) signalling pathway. In particular our model focuses on the dynamic response of NF-κB to an external stimulus. Each biochemical species in the pathway is represented by a specific Bio-PEPA component and the external stimulus is abstracted by time-dependent Bio-PEPA events(More)
We used on-line electron capture dissociation (ECD) for the large scale identification and localization of sites of phosphorylation. Each FT-ICR ECD event was paired with a linear ion trap collision-induced dissociation (CID) event, allowing a direct comparison of the relative merits of ECD and CID for phosphopeptide identification and site localization.(More)
In this paper we consider a model for different sorting of receptors of Fibroblast Growth Factor via the endocytotic pathway. In order to accurately model the relocation in the different compartments of the cell by the ligand-receptor complex, we use the stochastic version of Bioambients. The stochastic simulation is carried out using BAM (BioAmbient(More)
