Epigenetic Alteration of DNA, RNA or Protein (EADR)

Disease Class: Breast cancer [ICD-11: 2C60.3] [1], [2]

• Resistant Disease: Breast cancer [ICD-11: 2C60.3]
• Resistant Drug: Doxorubicin
• Molecule Alteration: Expression; Down-regulation
• Experimental Note: Identified from the Human Clinical Data
• Cell Pathway Regulation: TGF-beta/Wnt/G protein signaling pathway; Regulation; N.A.
• In Vitro Model: MCF-7 cells; Breast; Homo sapiens (Human); CVCL_0031
• Experiment for Molecule Alteration: qRT-PCR
• Experiment for Drug Resistance: MTT assay
• Mechanism Description: Compared to the breast cancer tissues from chemotherapy responders, 10 miRNAs were identified to be dysregulated in the chemoresistant breast cancer tissues. Three of these miRNAs were up-regulated (miR-141, miR-200c, and miR-31), and 7 were down-regulated (let-7e, miR-576-3p, miR-125b-1, miR-370, miR-145, miR-765, and miR-760). And miR-760 downregulation can enhance glioblastoma cells resistance to temozolomide through TGF-beta signaling pathway.

Regulation by the Disease Microenvironment (RTDM)

Disease Class: Breast cancer [ICD-11: 2C60.3] [4]

• Sensitive Disease: Breast cancer [ICD-11: 2C60.3]
• Sensitive Drug: Doxorubicin
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Epithelial mesenchymal transition signaling pathway; Inhibition; hsa01521
• In Vitro Model: MCF-7/DOX cells; Breast; Homo sapiens (Human); CVCL_0031
• Experiment for Molecule Alteration: RT-PCR
• Experiment for Drug Resistance: CCK8 assay
• Mechanism Description: miR760 mediates chemoresistance through inhibition of epithelial mesenchymal transition in breast cancer cells, overexpression of miR760 suppressed the expression of Nanog, a transcriptional factor involved in chemoresistance, and resulted in the reversal of EMT in breast cancer cells.
