Drug Resistance Data Categorized by Their Corresponding Mechanisms

Metabolic Reprogramming via Altered Pathways (MRAP)

Key Molecule: Metastasis associated in colon cancer protein 1 (MACC1) [1]

• Metabolic Type: Glucose metabolism
• Resistant Disease: HER2-positive advanced gastric cancer [ICD-11: 2B72.1]
• Resistant Drug: Trastuzumab
• Molecule Alteration: Expression; Up-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Human papillomavirus infection; Activation; hsa05165
• In Vitro Model: BGC823 cells; Gastric; Homo sapiens (Human); CVCL_3360
• In Vitro Model: NCI-N87 with high HER2 expressions cells; Stomach; Homo sapiens (Human); CVCL_1603
• In Vitro Model: MkN28 cells; Gastric; Homo sapiens (Human); CVCL_1416
• In Vitro Model: MKN45 parental cells with high HER2 expressions; Stomach; Homo sapiens (Human); CVCL_0434
• In Vitro Model: SGC-7901 cells; Gastric; Homo sapiens (Human); CVCL_0520
• Experiment for Drug Resistance: MTT assay
• Mechanism Description: Overexpression of MACC1-induced trastuzumab resistance, enhanced the Warburg effect, and activated the PI3K/AKT signaling pathway, while downregulation of MACC1 presented the opposite effects.
