| Outline of Final Research Achievements |
Telomerase is crucial of cellular immortalization and cancer progression. Telomerase activity is primarily regulated by the expression of telomerase reverse transcriptase (TERT) which is a protein catalytic subunit of telomerase. In this study, we performed that introduction of a normal human chromosome 3 into OSCC cell line, HSC3, using microcell-mediated chromosome transfer (MMCT). As results, these hybrid clones also showed remarkable transcriptional suppression of TERT expression compared with parental HSC3 cells. To identify the gene responsible for the regulation of TERT transcription, we performed RNA-sequence analysis using parental HSC3 cells, telomerase negative HSC3 microcell hybrids with a chromosome 3 (HSC3#3) and its revertant clones (HSC3#3R) with reactivated telomerase. As a result, we identification of 11 candidate genes which as novel TERT suppressor genes.
