Outline of Final Research Achievements |
Regulatory mechanisms by which interaction between GD3 and its associating molecule, neogenin on the cell surface of melanoma cells were analyzed with focus on the intracytoplasmic domain of neogenin (Ne-ICD). When a protease inhibitor was added to the culture medium, increased levels of Ne-ICD was detected in GD3+ cells, while it was hard to detect when a gamma-secretase inhibitor was added, suggesting that Ne-ICD was generated by recruiting gamma-secretase to lipid rafts by GD3 expression. By ChIP-sequencing, target genes that are driver by Ne-ICD have been identified, and those genes have been up-regulated by the introduction of Ne-ICD cDNA.
