Drug Resistance Data Categorized by Their Corresponding Mechanisms

Drug Inactivation by Structure Modification (DISM)

Key Molecule: Glutathione S-transferase P (GSTP1) [14]

• 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.

Both inhibitors were also able to significantly reduce migration (p < 0.001) and invasion (p < 0.001).

Key Molecule: Multidrug resistance protein 1 (ABCB1) [14]

• Molecule Alteration: Expression; Up-regulation
• Resistant Disease: Anaplastic astrocytoma [ICD-11: 2A00.04]
• Experimental Note: Identified from the Human Clinical Data
• Cell Pathway Regulation: Protein kinase C signaling pathways; Inhibition; hsa04310
• In Vitro Model: Malignant gliomas tissue; N.A.
• Experiment for Molecule Alteration: Immunohistochemistry assay
• Experiment for Drug Resistance: Oncotech EDR assay
• Mechanism Description: On the other hand, the frequency of LDR that we noted for paclitaxel (20%) and vincristine (20%) was similar to the clinical response rates for these compounds. These data suggest that although MDR1 expression by glial tumors may not be the dominant direct cellular process responsible for tumor resistance to natural products, other mechanisms are present that diminish their activity. The clinical mechanisms of natural product resistance may be a multifactorial function of endothelial expression of MDR1 at the blood-brain barrier in conjunction with glial tumor cell expression of alternative efflux pumps, such as MRP, altered tubulin with lower affinity binding sites, and/or protein kinase C signaling pathways that suppress apoptosis.

• Experiment for Drug Resistance: MTT assay
• Mechanism Description: ATG12 and HMGB2 were the direct targets of miR-23b-3p. Meanwhile, ATG12 and HMGB2 were positively associated with the occurrence of autophagy. Reducing the expression of these target genes by siRNA or inhibition of autophagy both sensitized GC cells to chemotherapy. These findings suggest that a miR-23b-3p/ATG12/HMGB2/autophagy-regulatory loop has a critical role in MDR in GC. In addition, miR-23b-3p could be used as a prognostic factor for overall survival in GC. miR-23b-3p inhibited autophagy mediated by ATG12 and HMGB2 and sensitized GC cells to chemotherapy, and suggested the potential application of miR-23b-3p in drug resistance prediction and treatment.

Meanwhile, the suppression of ZNRD1 led to a decrease in ABCB1.

• Experiment for Molecule Alteration: ATPase assay
• Experiment for Drug Resistance: MTT assay
• Mechanism Description: Through calcein assays, we found that epimagnolin A inhibited the ABCB1-mediated export of calcein. This result suggests that epimagnolin A behaved as inhibitor or substrate for ABCB1. In ATPase assays, epimagnolin A stimulated ABCB1-dependent ATPase activity. This result indicates that epimagnolin A was recognised as a substrate by ABCB1, since ABCB1 utilises energy derived from ATP hydrolysis for substrate transport. Furthermore, in MTT assays we found that the cytotoxicity of daunorubicin, doxorubicin, vinblastine, and vincristine was enhanced by epimagnolin A in a manner comparable to verapamil, a typical substrate for ABCB1.
