Title: Complex diseases as altered biological networks
1Complex diseases as altered biological networks
GRAPH (V,E) Vertices Biological entities
(with attributes) Edges Relation between
entities (QUANTITATIVE!!)
2Complex diseases as dynamic systems
INPUT VAR Information of the patient Genetic,
immunologic...OUTPUT VAR Diagnosis-prognosis.T
HE GOAL Input into the model, Simulate, Output
the result
I N P U T
O U T P U T
3Modelling the biological network/system
MODELS AND SUBMODELS From the cell to a subsystem
VERTICES Microarray data analysis, model
KOs...EDGES Biochemical/molecular studies,
microarray data analysis, text mining, proteomic
data analysis... We should obtain a set of
equations for each edge.INPUT SNPs, DNA
polymorphisms, epidemiological, physiological,
immunological data... OUTPUT Probability
distribution/values to predict evolution of the
disease, possible treatments...
(remember Pareto's Law most of the consequences
stems from a few causes)
