Drug Sensitivity Data Categorized by Their Corresponding Mechanisms

Unusual Activation of Pro-survival Pathway (UAPP)

Disease Class: Osteosarcoma [1]

• Sensitive Disease: Osteosarcoma [ICD-11: 2B51.0]
• Sensitive Drug: Doxorubicin
• Molecule Alteration: Expression; Down-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Cell proliferation; Inhibition; hsa05200
• In Vitro Model: U2OS cells; Bone; Homo sapiens (Human); CVCL_0042
• Experiment for Molecule Alteration: Western blot analysis
• Experiment for Drug Resistance: MTT assay
• Mechanism Description: The miR-101 not only decreases the formation of autophagic vesicles but also reduces the expression of LC-3II and Atg 4. This part of the study shows that miR-101 blocks chemotherapy-induced autophagy in OS cells. The sensitivity of OS cells to chemotherapy is increased by miR-101 blocked autophagy. miR-101 blocked the chemotherapy induced autophagy, and the blocked autophagy by miR-101 enhances the sensitivity of the OS cell line U-2 in vitro.
