| Outline of Final Research Achievements |
The tumor microenvironment plays an essential role in cancer progression, however, the mechanism of cancer progression induced by acidic pH microenvironment is still largely unknown. In this study, acidic pH cell culture system was established to identify the transcriptional-metabolic pathways for cancer progression under acidic pH tumor microenvironment.
As a result of this research, we established a simple model culture system to maintain acidic pH for at least 3 days and identified SREBP2 as a key transcriptional regulator under acidic pH using integration of comprehensive gene expression analysis and transcription factor motif analysis and we published our findings (Cell Reports, 2017).Moreover, accumulation and metabolic pathway specific to acidic pH are under investigation.
