Abstract:

Malignant melanoma is an aggressive tumor of the skin and
seems to be resistant to current therapeutic approaches.
Melanocytic transformation is thought to occur by sequential
accumulation of genetic and molecular alterations able to
activate the Ras/Raf/MEK/ERK (MAPK) and/or the PI3K/AKT (AKT)
signalling pathways. Specifically, mutations of B-RAF activate
MAPK pathway resulting in cell cycle progression and apoptosis
prevention. According to these findings, MAPK and AKT pathways
may represent promising therapeutic targets for an otherwise
devastating disease.Here we show a computational model able to
simulate the main biochemical and metabolic interactions in the
PI3K/AKT and MAPK pathways potentially involved in melanoma
development. Overall, this computational approach may
accelerate the drug discovery process and encourages the
identification of novel pathway activators with consequent
development of novel antioncogenic compounds to overcome tumor
cell resistance to conventional therapeutic agents. The source
code of the various versions of the model are available as S1
Archive.
