           2 Epigenetic Phenomena Related to This Phenotype Click to Show/Hide the Full List

  Epigenetic Phenomenon1

Hypoacetylation of SLC22A7 in Hepatocellular carcinoma (compare with non-tumor adjacent tissue) [ 1 ]

Location

Promoter

Epigenetic Type

Histone acetylation Experiment Method RT-qPCR

Related Molecular Changes

Down regulation ofSLC22A7 Experiment Method Western Blot

Studied Phenotype

Hepatocellular carcinoma[ ICD-11:2C12.02]

Experimental Material

Hepatocellular carcinoma cell lines (BEL-7402 and SMMC-7721)

Additional Notes

Significant increases in SLC22A7 mRNA were observed when these cancer cells were cultured in the presence of histone deacetylase (HDAC) inhibitors.

  Epigenetic Phenomenon2

Hypoacetylation of SLC22A7 in Hepatocellular carcinoma [ 2 ]

Location

Promoter

Epigenetic Type

Histone acetylation Experiment Method .

Related Molecular Changes

Down regulation ofSLC22A7 Experiment Method RT-qPCR

Studied Phenotype

Hepatocellular carcinoma[ ICD-11:2C12]

Experimental Material

SMMC-7721 HCC cells

Additional Notes

Abnormal enrichment of sirtuin 7 (SIRT7), histone deacetylase 7 (HDAC7) and lysine acetyltransferase 8 (KAT8) at the promoter of OAT2 caused histone hypoacetylation and OAT2 downregulation.
