Drug Sensitivity Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Disease Class: Colorectal cancer [ICD-11: 2B91.1] [1]

• Sensitive Disease: Colorectal cancer [ICD-11: 2B91.1]
• Sensitive Drug: Fluorouracil
• Molecule Alteration: Expression; Down-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Cell apoptosis; Activation; hsa04210
• Cell Pathway Regulation: Cell viability; Inhibition; hsa05200
• Cell Pathway Regulation: PTEN/PI3K/AKT signaling pathway; Activation; hsa05235
• In Vitro Model: HCT8 cells; Colon; Homo sapiens (Human); CVCL_2478
• Experiment for Molecule Alteration: qRT-PCR
• Experiment for Drug Resistance: MTT assay; Transwell assay; Flow cytometry assay
• Mechanism Description: miR-543 enhanced drug resistance by down-regulating the expression of phosphatase and tensin homolog (PTEN), which negatively regulates protein kinase B (AkT) activation while an elevated expression of PTEN reversed the chemoresistance of miR-543-overexpressing HCT8 cells to 5-FU.
