Combination Pair ID: 89
Pair Name Daidzein, Gefitinib
Partner Name Gefitinib
Disease Info [ICD-11: 2C25] Lung cancer Investigative
Biological Phenomena Induction-->Blockade of cell cycle in G0/G1 phase
Gene Regulation Down-regulation Expression AKT1 hsa207
Down-regulation Expression EGFR hsa1956
Up-regulation Activity JUN hsa3725
Up-regulation Activity MAP3K5 hsa4217
Down-regulation Expression MAPK1 hsa5594
Up-regulation Activity MAPK8 hsa5599
Up-regulation Activity ROS1 hsa6098
Down-regulation Expression SOAT1 hsa6646
In Vitro Model A-549 Lung adenocarcinoma Homo sapiens (Human) CVCL_0023
In Vivo Model 4×10⁶ A549 cancer cells in Matrigel serum free medium (BD Biosciences) suspension were subcutaneously injected into 8-week-old male NU/NU mice hind legs.
Result Daidzein Synergizes with Gefitinib to Induce ROS/JNK/c-Jun Activation and Inhibit EGFR-STAT/AKT/ERK Pathways to enhance Lung Adenocarcinoma cells chemosensitivity
Combination Pair ID: 647
Pair Name Daidzein, Topotecan
Partner Name Topotecan
Disease Info [ICD-11: 2C60] Breast cancer Investigative
Biological Phenomena Induction-->Blockade of cell cycle in G2/M phase
Gene Regulation Down-regulation Expression ABCG2 hsa9429
Up-regulation Expression BAX hsa581
Down-regulation Expression BCL2 hsa596
In Vitro Model MCF-7 Invasive breast carcinoma of no special type Homo sapiens (Human) CVCL_0031
In Vivo Model Adult female athymic nude mice (six-week-old) were injected with MCF7 cells (5×10⁶ cells/mouse) to construct subcutaneous breast cancer xenografts.
Result Daidzein enhances the anticancer effect of topotecan and reverses BCRP-mediated drug resistance in breast cancer.
Combination Pair ID: 994
Pair Name Daidzein, Cisplatin
Partner Name Cisplatin
Disease Info [ICD-11: 2C25] Lung cancer Investigative
Biological Phenomena Induction-->Apoptosis
Gene Regulation Down-regulation Expression MMP9 hsa4318
In Vitro Model A-549 Lung adenocarcinoma Homo sapiens (Human) CVCL_0023
Result This in vitro synergistic effect was mediated by suppression of MMP-9 and not by oxidative stress or Cas3-activated apoptosis. This study provides the basis for an in vivo and clinical trial of DZ-NS with concurrent chemotherapy.
