2 Epigenetic Phenomena Related to This Phenotype | Click to Show/Hide the Full List | |||
|
Epigenetic Phenomenon 1 |
Hypoacetylation of ABCB4 in breast cancer (compare with doxorubicin-resistant counterpart cells) | [ 2 ] | |||
|
Location |
Promoter | ||||
|
Epigenetic Type |
Histone acetylation | Experiment Method | Chromatin immunoprecipitation | ||
|
Related Molecular Changes |
Down regulation of ABCB4 | Experiment Method | RT-qPCR | ||
|
Studied Phenotype |
Breast cancer [ ICD-11: 2C60-2C6Z] | ||||
|
Experimental Material |
Multiple cell lines of human | ||||
|
Additional Notes |
ABCB4 was overexpressed in doxorubicin-resistant breast cancer cells compared to their doxorubicin-sensitive counterparts, which was associated with reduced DNA methylation as well as increased histone acetylation at the ABCB4 promoter. | ||||
|

Epigenetic Type |
Methylation | Experiment Method | Methylation-specific PCR | ||
|
Studied Phenotype |
Nodular goiter [ ICD-11: 5A01.Z] | ||||
|
Experimental Material |
