Brain cancer [ICD-11: 2A00]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Drug Inactivation by Structure Modification (DISM)

Key Molecule: Glutathione S-transferase P (GSTP1) [2]

• Molecule Alteration: Expression; Up-regulation
• Resistant Disease: Malignant glioma [ICD-11: 2A00.2]
• Experimental Note: Identified from the Human Clinical Data
• In Vitro Model: Malignant gliomas tissue; N.A.
• Experiment for Molecule Alteration: Immunohistochemistry assay
• Experiment for Drug Resistance: EDR assay
• Mechanism Description: In vitro drug resistance in malignant gliomas was independent of prior therapy. High-grade glioblastomas showed a lower level of extreme drug resistance than low-grade astrocytomas to cisplatin (11% versus 27%), temozolomide (14% versus 27%), irinotecan (33% versus 53%), and BCNU (29% versus 38%). A substantial percentage of brain tumors overexpressed biomarkers associated with drug resistance, including MGMT (67%), GSTP1 (49%), and mutant p53 (41%). MGMT and GSTP1 overexpression was independently associated with in vitro resistance to BCNU, whereas coexpression of these two markers was associated with the greatest degree of BCNU resistance.

Chemotherapy was found to increase the expression levels of miR-17-5p, which further repressed PTEN levels, contributing to the development of chemo-resistance.
