  sub:_6 prov:value """Importantly, it has been demonstrated that hypoxia promotes tumour cell invasion by
inducing the expression of the Met receptor [54]. This establishes a mechanism
whereby transformed cells can be spurred to exit a hypoxic microenvironment and
invade the surrounding tissues, which provide more favourable growth conditions.
Because HIF-1a is involved in Met gene expression, the constitutive activation
of HIF-1a as a consequence of pVHL deregulation provides a mechanism explaining
the observation that the expression of HGF and Met receptor is associated with
genetic alterations of VHL in primary RCC.""" ;
