Regulation by the Disease Microenvironment (RTDM)

Disease Class: Ovarian cancer [1]

• Resistant Disease: Ovarian cancer [ICD-11: 2C73.0]
• Resistant Drug: Carboplatin
• 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 proliferation; Inhibition; hsa05200
• In Vitro Model: OVCAR3 cells; Ovary; Homo sapiens (Human); CVCL_0465
• In Vitro Model: MES-OV cells; Ovary; Homo sapiens (Human); CVCL_CZ92
• In Vivo Model: Mouse xenograft model; Mus musculus
• Experiment for Molecule Alteration: qPCR
• Experiment for Drug Resistance: SRB colorimetric assay; Flow cytometry assay
• Mechanism Description: The miR-200 family has major roles in EMT and taxane resistance in taxane selected ovarian cancer cell variants, and that re-introduction of miR-200s was not sufficient to fully reverse the mesenchymal phenotype in these variants. Although miR-200s were able to restore paclitaxel sensitivity in one of the variants, they did not do so in the other, and produced resistance to carboplatin in both. The divergent effects of miR-200s on taxane and carboplatin cytotoxicity should be further investigated in ovarian cancers. miR-200c and miR-141 mimics conferred resistance to carboplatin in MES-OV/TP cells, similar to OVCAR-3/TP, but sensitized MES-OV to paclitaxel. Several genes involved in balancing oxidative stress were altered in OVCAR-3/TP 200c141 cells compared to controls. The miR-200 family plays major, cell-context dependent roles in regulating EMT and sensitivity to carboplatin and paclitaxel in OVCAR-3 and MES-OV cells.

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Disease Class: Non-small cell lung cancer [2]

• Resistant Disease: Non-small cell lung cancer [ICD-11: 2C25.Y]
• Resistant Drug: Cisplatin
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Cell apoptosis; Activation; hsa04210

Luciferase activity assay and Western blot analysis confirmed that PDCD4 is a direct target of miR-141. Inhibition of miR-141 in A549/DDP cells markedly increased cisplatin sensitivity and apoptosis, which was partially abrogated by PDCD4 inhibition, indicating that PDCD4 is a functional target of miR-141 in of the regulation of cisplatin sensitivity.

• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Cell migration; Inhibition; hsa04670
• Cell Pathway Regulation: Cell proliferation; Inhibition; hsa05200

In addition, miR-141 upregulation reduced the in vivo growth of IMR-32 tumor explants. FUS was found to be inversely regulated by miR-141 in NB. Small interfering RNA (siRNA)-induced FUS downregulation had similar tumor-suppressive effects as miR-141 upregulation on NB cell proliferation, cell cycle progression, migration and cisplatin chemosensitivity.

Disease Class: Gastric cancer [6]

• Experiment for Molecule Alteration: qRT-PCR
• Experiment for Drug Resistance: MTT assay
• Mechanism Description: Knockdown miR-141 expression in 7901/DDP and 7901 cells could significantly improve cisplatin sensitivity. Over-expression of miR-141 resulted in (+) resistance to cisplatin in both gastric cancer cells. We also demonstrated that miR-141 directly targets kEAP1 by luciferase reporter assay, and that down-regulation of kEAP1 induces cisplatin resistance. Conversely, over-expression of kEAP1 significantly (+) cisplatin sensitivity. Our 75 pairs of tissues also showed that kEAP1 was significantly up-regulated in H. pylori-positive tissues.

Docetaxel

• In Vivo Model: Mouse xenograft model; Mus musculus
• Experiment for Molecule Alteration: qRT-PCR
• Experiment for Drug Resistance: MTT assay
• Mechanism Description: miR-141 affected the chemosensitivity of BC cells to docetaxel by directly targeting EIF4E, due to its anti-apoptotic properties. Transfection of miR-141 inhibitor could significantly promote docetaxel-induced apoptosis and change the expression of Bax and Bcl-2. However, when the BC cells were transfected with siRNA-EIF4E, the data showed opposite results. It suggested that EIF4E is partly responsible for the miR-141-induced apoptosis which is related to the mitochondrial apoptosis pathway. In the previous studies, antisense Bcl-2 treatment (+) sensitivity to tamoxifen in HER2-positive cells in tamoxifen-resistant BC cells.
