    Alzheimer’s disease (AD) is a neurodegenerative disease which results in synaptic depression and complete destruction in neurons in the final stages. Many pathogenesis has so far been attributed to AD but the most commonly explained pathomechanism is based on the amyloid cascade theory which results in formation of amyloid beta plaques outside and hyper phosphorylated neurofibrillary tangles of tau protein inside the neurons. One of the most well-known symptoms of AD is the disability to learn and form new memories and transform them into long term memory. The most commonly studied mechanism in memory formation, is the “long term potentiation”. Although many mechanisms and molecules are... 

    Discovering dominant pathways and signal-response relationships in signaling networks through nonparametric approaches

    , Article Genomics ; Volume 102, Issue 4 , October , 2013 , Pages 195-201 ; 08887543 (ISSN) Nassiri, I ; Masoudi Nejad, A ; Jalili, M ; Moeini, A ; Sharif University of Technology
    A signaling pathway is a sequence of proteins and passenger molecules that transmits information from the cell surface to target molecules. Understanding signal transduction process requires detailed description of the involved pathways. Several methods and tools resolved this problem by incorporating genomic and proteomic data. However, the difficulty of obtaining prior knowledge of complex signaling networks limited the applicability of these tools. In this study, based on the simulation of signal flow in signaling network, we introduce a method for determining dominant pathways and signal response to stimulations. The model uses topology-weighted transit compartment approach and comprises...
