Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Disease Class: Pancreatic cancer [ICD-11: 2C10.3] [1]

• Resistant Disease: Pancreatic cancer [ICD-11: 2C10.3]
• Resistant Drug: Fluorouracil
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• In Vitro Model: PANC-1 cells; Pancreas; Homo sapiens (Human); CVCL_0480
• In Vitro Model: PATU8988 cells; Pancreas; Homo sapiens (Human); CVCL_1846
• In Vitro Model: 293TN cells; Pancreas; Homo sapiens (Human); CVCL_UL49
• Experiment for Molecule Alteration: qRT-PCR
• Experiment for Drug Resistance: 5-FU and gemcitabine assay; CCK8 assay; Wound healing assay; Transwell chamber invasion assay
• Mechanism Description: miRNA-221-3p desensitizes pancreatic cancer cells to 5-fluorouracil by targeting RB1. miR221-3p down-regulated RB1 expression by directly binding to its 3'-UTR and therefore caused increased several aspects of pancreatic cancer pathogenesis, including proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT).
