| Outline of Final Research Achievements |
Ubiquitous MITF-related transcription factors TFEB, TFE3 and TCF4 were found to be significantly over-expressed in cultured melanocytes when the cAMP level was suppressed below steady state. To discover relevant functional miRNA-transcription factor relationships, differentially expressed miRNAs were screened by miRNA microarray. Three miRNA, miR-30b, -146a, and -29a, including miRNA known to interact with these transcription factors, were found to be over-expressed. To explore genome-wide binding sites of TCF4 transcription factor, genome-wide ChIP-seq was performed on cultured melanocytes with seven anti-TCF4 antibodies. However, even though in the entire chromosome views the TCF4 data show more peaks than the negative control, all seven TCF4-specific antibody validation results appeared to be negative, since targeted deep sequencing reveals no significant results.
