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; 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. 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.

Cisplatin

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Disease Class: Testicular cancer [.] [2]

• Resistant Disease: Testicular cancer [.]
• Resistant Drug: Cisplatin
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• Experiment for Molecule Alteration: RT-qPCR with "Low Density Array"
• Experiment for Drug Resistance: MTT assay
• Mechanism Description: Examining almost all known human micro-RNA species confirmed the miR-371-373 cluster as a promising target for explaining cisplatin resistance, potentially by counteracting wild-type P53 induced senescence or linking it with the potency to differentiate. Moreover, we describe for the first time an association of the up-regulation of micro-RNA species such as hsa-miR-512-3p/-515/-517/-518/-525 and down-regulation of hsa-miR-99a/-100/-145 with a cisplatin resistant phenotype in human germ cell tumors.
