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] [1]

• Resistant Disease: Pancreatic ductal adenocarcinoma [ICD-11: 2C10.0]
• Resistant Drug: Gemcitabine
• Molecule Alteration: Expression; Down-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.

• Experiment for Drug Resistance: MTS assay
• Mechanism Description: Among these miRs, 7 (miR-224, miR-424-3p, miR-130a, miR-224-star, miR-452, miR-181a-2-star, and miR-193b-5p) were downregulated in the PTX-resistant GC cell line, whereas the other 3 miRs (miR-3127-5p, miR-1287, and miR-4713-5p) were upregulated in the PTX-resistant GC cell line compared to the PTX-sensitive GC cell line. AKT/ERK signaling was active in the PTX-resistant GC cell line.
