| Research Abstract |
HGF treatment of HepG2 hepatoma cells decreases expression of an oncogene ID1. This study showed that the decrease in ID1 is regulated through downregulation of Skp2, a component of E3 ubiquitin ligase, in the presence of HGF. However, Skp2 was involved in the regulation of ID1 expression by regulating transcription activity of Myc independently of ubiquitination. This study also showed that G9a histone methyltransferase, which expression may be regulated through Skp2/Myc/ID1, is involved in the alteration of H3K9me3 localization in cell nuclei induced by HGF, leading to the irreversible suppression of cancer cell proliferation by HGF.
