Fluorouracil

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Disease Class: Esophageal squamous cell carcinoma [ICD-11: 2B70.0] [1]

• Resistant Disease: Esophageal squamous cell carcinoma [ICD-11: 2B70.0]
• Resistant Drug: Fluorouracil
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• In Vitro Model: OE19 cells; Esophagus; Homo sapiens (Human); CVCL_1622
• In Vitro Model: kYSE410 cells; Esophagus; Homo sapiens (Human); CVCL_1352
• Experiment for Molecule Alteration: qPCR
• Mechanism Description: Chemotherapy resistant sublines were found to have specific miRNA signatures, and these miRNA signatures were different for the cisplatin vs 5-FU resistant cells from the same tumor cell line, and also for EAC vs ESCC cells with resistance to the same specific chemotherapy agent. Amongst others, miR-27b-3p, miR-193b-3p, miR-192-5p, miR-378 a-3p, miR-125a-5p and miR-18a-3p were dysregulated, consistent with negative posttranscriptional control of KRAS, TYMS, ABCC3, CBL-B and ERBB2 expression via these miRNAs.

• Resistant Drug: Cisplatin
• Molecule Alteration: Expression; Down-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• In Vitro Model: OE19 cells; Esophagus; Homo sapiens (Human); CVCL_1622
• In Vitro Model: kYSE410 cells; Esophagus; Homo sapiens (Human); CVCL_1352
• Experiment for Molecule Alteration: qPCR
• Mechanism Description: Chemotherapy resistant sublines were found to have specific miRNA signatures, and these miRNA signatures were different for the cisplatin vs 5-FU resistant cells from the same tumor cell line, and also for EAC vs ESCC cells with resistance to the same specific chemotherapy agent.

Oxaliplatin

Drug Sensitivity Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Disease Class: Hepatocellular carcinoma [ICD-11: 2C12.0] [2]

• Sensitive Disease: Hepatocellular carcinoma [ICD-11: 2C12.0]
• Sensitive Drug: Oxaliplatin
• Molecule Alteration: Expression; Down-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• In Vitro Model: LO2 cells; Uterus; Homo sapiens (Human); CVCL_6926
• In Vitro Model: Hep3B cells; Liver; Homo sapiens (Human); CVCL_0326
• In Vitro Model: Huh7 cells; Kidney; Homo sapiens (Human); CVCL_U442
• In Vivo Model: BALB/c nude mouse xenograft model; Mus musculus
• Experiment for Molecule Alteration: Immunofluorescence; qPCR; Luciferase reporter assay; Western blot
• Experiment for Drug Resistance: Clonogenic assay; Cumulative proliferation assay
• Mechanism Description: Based on previous findings, we hypothesized that miR-31-5p alters chemosensitivity and that miR-31-5p mimics may influence sensitivity to chemotherapeutics in HCC as well as in a variety of other cancers
