on the role of tyrosine kinase receptors and the phosphoinositide-3 kinase (PI3K) pathway in mesothelioma. The authors demonstrated differential involvement of 3 growth factor (GF) receptorsepidermal growth factor (EGF), insulin-like growth factor (IGF), and platelet-derived growth factor (PDGF) receptorsin PI3K-mediated survival of the malignant mesothelioma cells.
Survival of many cells under stress, particularly of myocytes, is dependent on PI3K pathway activation.

It is not often appreciated, however, that the PI3K pathway can be activated not only via tyrosine kinase receptors by GFs, but also via toll-like receptor by heat shock protein, bacterial lipopolysaccharide, and by tumor
