It has been shown that PDK1 is essential for KRAS-driven pancreatic cancer growth. In this dissertation a murine model was used to investigate the in vitro effect of PTEN-knockout (KO) in PDK1-deficient cells. The experiments showed a significant rescue effect after KO of PTEN, thereby validating PTEN-loss as a mechanism to survive PDK1 deletion induced growth arrest in PDAC cells. The quantitative protein analysis of PTEN-KO cells indicates that compensatory changes in PI3K/AKT signaling, such as p-AKT and mTOR upregulation, likely contribute to their resistance.
