ERBB2 phosphorylation is increased in HPV16 E6 expressing HFKs.

<p>(<b>A</b>) Western blot analysis of proteins with phosphorylated tyrosine residues following EGF withdrawal (left) or PBS starvation (right) from HFK lysates stably expressing HPV16 E6 (E6) or the pLentiN6.3 control vector (C). (<b>B</b>) and (<b>C</b>) Western blot analyses probing the phosphorylation status of EGFR (<b>B</b>) or INSRβ/IGFRβ (<b>C</b>) using phosphospecific antibodies in HPV16 E6 (E6) or LXSN control vector (C) expressing stable HFKs. Representative experiments from three independent experiments are shown in panels A, B and C. Quantifications relative to actin are shown below each panel.
