  sub:_5 prov:value """We have shown recently that Flt-1 VEGFR is expressed in the human MM cell line and
patient MM cells and is tyrosine-phosphorylated upon VEGF stimulation (12). Because
Flt-1 and the p85 subunit of PI 3-kinase were associated when overexpressed
in yeast cells (54), we next determined whether this interaction is biologically
significant in MM cells. Flt-1 was immunoprecipitated from VEGF treated and non-treated
MM.1S cells followed by immunoblotting with anti-p85 Ab. As illustrated
in Fig.5a, p85 is constitutively associated with Flt-1, suggesting that PI 3-kinase
participates in Flt-1-mediated VEGF signal transduction.""" ;
