| Outline of Final Research Achievements |
In this study, we investigated the role of PITX1 in the SASP pathway and conducted research to clarify the relationship between cellular senescence and carcinogenesis mechanism. As a result, we found that PITX1 is directly involved in the positive expression regulation of both IL-6 and IL-8, which are known as the major marker factors of the SASP pathway. Furthermore, it was accompanied by increased p16 mRNA transcription level which known cell senescence factor in the SASP pathway. On the other hand, we succeeded in establishing of the Pitx1 KO mouse which can conditionally knock down of Pitx1 gene allele. These results suggested that PITX1 may function as a novel regulatory factor in a series of molecular signals in the SASP pathway.
