| Outline of Final Research Achievements |
The UPR (unfolded protein response) is a cellular adaptive mechanism that plays an important role in cancer cell survival and proliferation within particular tumor microenvironment. In this study, we focused on two proteins: one is PERK, a central regulatory protein in the UPR, and the other is TBL2, a new function molecule which can interact with PERK during stress. Then, we examined roles of the PERK signaling pathway in cancer cell adaptation to tumor microenvironment by knocking down PERK or TBL2. In addition, aiming at the development of treatment strategy, we searched factors which had a synthetic lethal relationship under conditions inhibiting function of the PERK signaling pathway.
