Drug Resistance Data Categorized by Their Corresponding Diseases

ICD-02: Benign/in-situ/malignant neoplasm

Diffuse large B-cell lymphoma [ICD-11: 2A81]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Key Molecule: Zinc finger C3HC-type containing 1 (ZC3HC1) [1]

• Molecule Alteration: Expression; Up-regulation
• Resistant Disease: NPM-ALK-Positive anaplastic large cell lymphoma [ICD-11: 2A81.8]
• Experimental Note: Revealed Based on the Cell Line Data
• In Vitro Model: SUP-M2 cells; Colon; Homo sapiens (Human); CVCL_2209
• In Vitro Model: KARPAS-299 cells; Peripheral blood; Homo sapiens (Human); CVCL_1324
• Experiment for Molecule Alteration: Western blotting analysis
• Experiment for Drug Resistance: Proliferation assay
• Mechanism Description: For KARPAS-299-derived cell lines, we observed oncogene overexpression as the main resistance mechanism, whereas in SUP-M2-derived cell lines, we identified several point mutations located within the NPM-ALK kinase domain, which could explain drug resistance.
