In colorectal cancer (CRC), hypoxia causes resistance to therapy and promotes metastasis. Mutation of the tumor suppressor TP53 provides a selective advantage to cancer cells under conditions of hypoxia, but little is known about the mediators of this effect. In this thesis I could show that the hypoxia inducible factor 1 alpha subunit (HIF1A) directly represses the MIR34A gene in TP53-defective CRC cells, whereas expression of MIR34A was induced in TP53-proficient CRC cells exposed to hypoxia. Down-regulation of MIR34A was required for hypoxia-induced epithelial to mesenchymal transition (EMT), invasion and migration, and activation of STAT3 in CRC cells. In this study the PPP1R11 (protein phosphatase 1 regulatory inhibitor subunit 11; ...
