Doxorubicin

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

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

• Resistant Disease: Breast cancer [ICD-11: 2C60.2]
• Resistant Drug: Doxorubicin
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• In Vitro Model: MCF-7 cells; Breast; Homo sapiens (Human); CVCL_0031
• In Vitro Model: MCF-7 cells; Breast; Homo sapiens (Human); CVCL_0031
• Experiment for Molecule Alteration: MiRNA microarray; RT-PCR; Western blot
• Experiment for Drug Resistance: MTT assay
• Mechanism Description: MicroRNAs play important roles in regulation of gene expression involved in crucial biological processes including development, differentiation, apoptosis, and proliferation through down-regulation of target mRNA by degrading them or inhibiting their translation, and specific inhibition of MAPK signaling is important in the regulation of MCF-7/AdrVp cells resistance to chemotherapy drug.

Gemcitabine

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Disease Class: Pancreatic ductal adenocarcinoma [ICD-11: 2C10.0] [2]

• Resistant Disease: Pancreatic ductal adenocarcinoma [ICD-11: 2C10.0]
• Resistant Drug: Gemcitabine
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• In Vitro Model: SW1990 cells; Pancreas; Homo sapiens (Human); CVCL_1723
• In Vitro Model: SW1990 cells; Pancreas; Homo sapiens (Human); CVCL_1723
• Experiment for Molecule Alteration: qPCR
• Mechanism Description: Differential gene expression between parental and gemcitabine-resistant pancreatic cancer cell. Consequently, compared with SW1990 cells, 28 microRNAs were upregulated and 28 microRNAs were decreased (fold change>=2) in SW1990/GEM cells. Then, the expression of some differential microRNAs was confirmed by Q-PCR assays. We found that miR-643, miR-1261, miR483-5p, miR-371a-5p, and miR-373-3p were upregulated and that the expression of miR-4455, miR-3676, miR-4650, miR4791, and miR-4644 was decreased in SW1990/GEM cells. Generally, the tendency of expression changes was consistent between microRNA-seq and Q-PCR results.
