Hasaneen et al., Am J Physiol Lung Cell Mol Physiol 2007 : Our results show : 1 ) a significant increase in human lung microvascular endothelial cell ( HMVEC-L ) proliferation, migration, and tube formation following incubation in conditioned media ( CM ) from HASM cells exposed to mechanical strain ; 2 ) mechanical strain of HASM cells induced VEGF expression and release ; 3 ) VEGF neutralizing antibodies inhibited the proliferation, migration, and tube formations of HMVEC-L induced by the strained airway smooth muscle CM ; 4 ) mechanical strain of HASM induced a significant increase in hypoxia-inducible factor-1alpha ( HIF-1alpha ) mRNA and protein, a transcription factor required for VEGF gene transcription ; and 5 ) mechanical strain of HASM induced HIF-1alpha/VEGF through dual phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) and ERK pathways
Basu et al., PloS one 2011 (Kidney Neoplasms) : We found that the knockdown of raptor ( using siRNA ) significantly decreased CNI induced VEGF promoter activity as observed by promoter-luciferase assay, suggesting the role of mTOR complex1 (mTORC1) in CNI induced VEGF transcription
Land et al., J Biol Chem 2007 (Neoplasms...) : Our work shows that activation of mTOR by Ras homologue enriched in brain (Rheb) overexpression potently enhances the activity of HIF1alpha and vascular endothelial growth factor ( VEGF ) -A secretion during hypoxia, which is reversed with rapamycin
