Background:
Two mangostin compounds, gamma-mangostin and alpha-mangostin, show anticancer properties through the inhibition of cell proliferation and cell migration. Metastatic triple-negative breast cancer (TNBC) cells, including MDA-MB-231, highly express C-X-C chemokine receptor type 4 (CXCR4) to maintain reactive oxygen species (ROS) and cell migration.
Objectives:
This study was performed to analyze and compare different modes of action of γ-mangostin and α-mangostin as antimigratory effects targeted on CXCR4 in MDA-MB-231 as a model of TNBC cell.
Methods:
This study investigated the effect of γ-mangostin and α-mangostin using a series of assays, including Cell Counting Kit-8 (CCK-8) assay for cytotoxicity, wound healing assay for migration study, quantitative real-time polymerase chain reaction (qRT-PCR) for gene expression analysis, and flow cytometry for ROS measurement, along with in silico study to observe the binding between the compound and CXCR4.
Results:
The findings revealed half maximal inhibitory concentration (IC50) values of 25 and 20 μM for γ-mangostin and α-mangostin in MDA-MB 231 cells, respectively. Moreover, a concentration of 10 μM was used for the migration assay. Both γ-mangostin and α-mangostin significantly suppressed cell migration within 24 hours. The present gene expression studies revealed the downregulation of key migration-associated genes, namely Farp, CXCR4, and LPHN2, upon γ-mangostin treatment but not α-mangostin. Additionally, both γ-mangostin and α-mangostin increased cellular ROS generation, highlighting the same effect of γ-mangostin and α-mangostin ROS elevation to inhibit cancer cell migration. Molecular docking simulations further suggested a potential interaction between γ-mangostin and α-mangostin with CXCR4 in high affinity.
Conclusions:
These findings suggest that both γ-mangostin and α-mangostin inhibit breast cancer cell migration and induce cellular ROS levels in MDA-MB-231 cells; notably, γ-mangostin suppresses CXCR4 mRNA expression that might correlate to its activity to inhibit MDA-MB-231 cell migration.
Insights
Gamma-mangostin and alpha-mangostin inhibit breast cancer cell migration by increasing reactive oxygen species (ROS). Gamma-mangostin also downregulates CXCR4, a key migration gene in triple-negative breast cancer (TNBC) cells.
Area of Science:
- Pharmacology
- Molecular Biology
- Oncology
Background:
- Mangostin compounds, gamma-mangostin and alpha-mangostin, exhibit anticancer properties by inhibiting cell proliferation and migration.
- Metastatic triple-negative breast cancer (TNBC) cells, such as MDA-MB-231, overexpress C-X-C chemokine receptor type 4 (CXCR4), which is crucial for maintaining reactive oxygen species (ROS) and facilitating cell migration.
Purpose of the Study:
- To compare the mechanisms of action of gamma-mangostin and alpha-mangostin in inhibiting cell migration.
- To investigate the effects of these compounds on CXCR4 expression and ROS generation in MDA-MB-231 cells, a model for TNBC.
Main Methods:
- Cytotoxicity was assessed using the Cell Counting Kit-8 (CCK-8) assay.
- Cell migration was evaluated using wound healing assays and gene expression analysis via quantitative real-time polymerase chain reaction (qRT-PCR).
- Reactive oxygen species (ROS) levels were measured by flow cytometry, and molecular docking was employed for in silico analysis of compound-CXCR4 interactions.
Main Results:
- Both gamma-mangostin and alpha-mangostin significantly suppressed MDA-MB-231 cell migration within 24 hours at 10 μM.
- Gamma-mangostin treatment led to the downregulation of migration-associated genes (Farp, CXCR4, LPHN2), while alpha-mangostin did not.
- Both compounds increased cellular ROS generation, suggesting a common pathway for inhibiting cancer cell migration, and molecular docking indicated high-affinity binding to CXCR4.
Conclusions:
- Gamma-mangostin and alpha-mangostin effectively inhibit breast cancer cell migration and increase ROS levels in MDA-MB-231 cells.
- Gamma-mangostin's suppression of CXCR4 mRNA expression may be linked to its potent antimigratory activity in TNBC cells.
