Cancer&Entry Information

Cancer Name	hepatocellular carcinoma
ICD-0-3	C22.0
Methods	qPCR, ChIP, Luciferase reporter assay, RNA pull-down assay etc.
Sample	HCC tissues
Expression Pattern	up-regulated
Function Description	We found that aberrant upregulated intranuclear Linc00441 was reversely correlated with RB1 expression in human HCC samples. The gain- and loss-of-function investigation revealed that Linc00441 could promote the proliferation of HCC cells in vitro and in vivo with an apoptosis suppression and cell cycle rearrangement. Furthermore, RNA pull-down assay indicated the decreased level of RB1 induced by Linc00441 was associated with the incidental methylation by DNMT3A recruited by Linc00441. On the contrary, the transcription factor (TCF-4) enhanced H3K27 acetylation and direct transcription factor for Linc00441 was responsible for the upregulation of Linc00441 in HCC.
Pubmed ID	28300839
Year	2017
Title	Bidirectional transcription of Linc00441 and RB1 via H3K27 modification-dependent way promotes hepatocellular carcinoma.
