Drug Sensitivity Data Categorized by Their Corresponding Mechanisms

Unusual Activation of Pro-survival Pathway (UAPP)

Key Molecule: PI3-kinase alpha (PIK3CA) [1]

• Molecule Alteration: Missense mutation; p.E545K (c.1633G>A)
• Sensitive Disease: Bladder cancer [ICD-11: 2C94.0]
• Experimental Note: Identified from the Human Clinical Data
• Cell Pathway Regulation: MEK/ERK signaling pathway; Inhibition; hsa04011
• In Vitro Model: 5637 cells; Bladder; Homo sapiens (Human); CVCL_0126
• In Vitro Model: J82 cells; Bladder; Homo sapiens (Human); CVCL_0359
• In Vitro Model: RT4 cells; Bladder; Homo sapiens (Human); CVCL_0036
• In Vitro Model: T24 cells; Bladder; Homo sapiens (Human); CVCL_0554
• In Vitro Model: TCCSuP cells; Bladder; Homo sapiens (Human); CVCL_1738
• In Vivo Model: NSG mouse PDX model; Mus musculus
• Experiment for Drug Resistance: MTS assay; FACS assay
• Mechanism Description: Pictilisib activated the compensatory MEK/ERK pathways that likely contributed to pictilisib resistance, which was reversed by co-treatment with the RAF inhibitor sorafenib. RNA-sequencing of tumors resistant to treatment suggested that LSP1 down-regulation correlated with drug resistance.
