HIF-1alpha determines the metastatic potential of gastric cancer cells.

ABSTRACT: Gastric adenocarcinoma is characterised by rapid emergence of systemic metastases, resulting in poor prognosis due to vanished curative treatment options. Better understanding of the molecular basis of gastric cancer spread is needed to design innovative treatments. The transcription factor HIF-1alpha (hypoxia-inducible factor 1alpha) is frequently overexpressed in human gastric cancer, and inhibition of HIF-1alpha has proven antitumour efficacy in rodent models, whereas the relevance of HIF-1alpha for the metastatic phenotype of gastric adenocarcinoma remains elusive. Therefore, we have conducted a comprehensive analysis of the role of HIF-1alpha for pivotal metastasis-associated processes of human gastric cancer. Immunhistochemistry for HIF-1alpha showed specific staining at the invading
