Type(s) of Resistant Mechanism of This Drug

  EADR: Epigenetic Alteration of DNA, RNA or Protein

Drug Resistance Data Categorized by Their Corresponding Diseases

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

Mature B-cell neoplasms/lymphoma [ICD-11: 2A85]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Key Molecule: Growth arrest specific 5 (GAS5) [2]

• Molecule Alteration: Expression; Down-regulation
• Resistant Disease: Mantle cell lymphoma [ICD-11: 2A85.0]
• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Cell apoptosis; Inhibition; hsa04210
• Cell Pathway Regulation: Cell proliferation; Activation; hsa05200
• Cell Pathway Regulation: mTOR signaling pathway; Regulation; hsa04150
• In Vitro Model: Z138 cells; Peripheral blood; Homo sapiens (Human); CVCL_B077

• Experiment for Molecule Alteration: RT-PCR
• Experiment for Drug Resistance: Nigrosin exclusion analysis
• Mechanism Description: Small interfering RNAs (sirRNAs) targeting GAS5 protect the cell viability and proliferation of jeko-1 and z-138 cells from the inhibitory effects of mTOR inhibitors result in rapamycin resistance.

Prostate cancer [ICD-11: 2C82]

Drug Sensitivity Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Key Molecule: Growth arrest specific 5 (GAS5) [1]

• Molecule Alteration: Expression; Up-regulation
• Sensitive Disease: Prostate cancer [ICD-11: 2C82.0]
• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Cell proliferation; Inhibition; hsa05200
• In Vitro Model: DU-145 cells; Prostate; Homo sapiens (Human); CVCL_0105
• In Vitro Model: LNCaP cells; Prostate; Homo sapiens (Human); CVCL_0395
• In Vitro Model: PC3 cells; Prostate; Homo sapiens (Human); CVCL_0035
• In Vitro Model: 22RV1 cells; Prostate; Homo sapiens (Human); CVCL_1045
• In Vitro Model: PNT2C2 cells; Prostate; Homo sapiens (Human); CVCL_4889
• Experiment for Molecule Alteration: qRT-PCR
• Experiment for Drug Resistance: GAS5 assay; MTS assay
• Mechanism Description: First generation mTORC1, combined mTORC1/mTORC2 and dual PI3k/mTOR inhibitors all increased cellular GAS5 levels and inhibited culture growth in androgen-dependent (LNCaP) and androgen-sensitive (22Rv1) cell lines, but not in androgen-independent (PC-3 and DU 145) cell lines. The latter exhibited low endogenous GAS5 expression, and GAS5 silencing in LNCaP and 22Rv1 cells decreased the sensitivity to mTOR inhibitors, whereas transfection of GAS5 LncRNA sensitized PC-3 and DU 145 cells to these agents.
