                     Transcription-factor regulation
                            Nuclear receptor family 0 I3 (NR1I3) Health Activation
Uniprot ID
NR1I3_HUMAN
Interaction Name NR1I3-CYP2B6 interaction [2]
Studied Cell Lines Healthy subjects
Ensembl ID
ENSG00000143257
Description Nuclear receptor family 0 I3 (NR1I3) is reported to activate the transcription of CYP2B6 gene, which leads to an increased expression of the drug-metabolizing enzyme Cytochrome P450 2B6. As a result, the interaction between NR1I3 and CYP2B6 can activate the drug-metabolizing process of Cytochrome P450 2B6.
                     Non-coding RNA regulation
                            hsa-miR-25-3p Health Suppression
miRBase ID
MIMAT0000081
Interaction Name hsa-miR-25-3p--CYP2B6 regulation [1]
Studied Cell Lines HEK293 cell line
Description hsa-miR-25-3p is reported to suppress CYP2B6 mRNA translation by binding to the 3' untranslated region (3'UTR) of CYP2B6 mRNA, which leads to a decreased expression of the drug-metabolizing enzyme Cytochrome P450 2B6.

Interaction Name ATF5-CYP2B6 interaction [3]
Studied Cell Lines HepG2, Hep3B and Mz cell lines
Ensembl ID
ENSG00000169136
Description Activating TF factor 5 (ATF5) is reported to activate the transcription of CYP2B6 gene, which leads to an increased expression of the drug-metabolizing enzyme Cytochrome P450 2B6. As a result, the interaction between ATF5 and CYP2B6 can activate the drug-metabolizing process of Cytochrome P450 2B6.
                            Early growth response 1 (EGR1) Liver cancer Activation
Uniprot ID
EGR1_HUMAN
Interaction Name EGR1-CYP2B6 interaction [5]
Studied Cell Lines Ym17, Yh18 and COS-1 cell lines
Ensembl ID
ENSG00000120738
Description Early growth response 1 (EGR1) is reported to activate the transcription of CYP2B6 gene, which leads to an increased expression of the drug-metabolizing enzyme Cytochrome P450 2B6. As a result, the interaction between EGR1 and CYP2B6 can activate the drug-metabolizing process of Cytochrome P450 2B6.
                     DNA methylation
                            DNA methyltransferase (DNMT) Liver cancer Significant hypermethylation
Uniprot ID
DNMT1_HUMAN
Interaction Name DNMT-CYP2B6 interaction [4]
Studied Cell Lines Live tissue
Description DNA methyltransferase (DNMT) is reported to significantly hyper-methylate the CYP2B6 gene, which leads to a significantly decreased expression of the drug-metabolizing enzyme Cytochrome P450 2B6. As a result, the interaction between DNMT and CYP2B6 can significantly affect the drug-metabolizing process of Cytochrome P450 2B6.
