Background/Aim:
Cervical cancer is one of the leading causes of cancer death in women worldwide. BRM270 (BRMLife) has therapeutic potential for cancer treatment owing to its ability to inhibit cell proliferation, and expression of cluster of differentiation (CD) 133 in CD133+ cancer cells. This study was designed to evaluate the therapeutic effects of plant extract formulation BRM270 against cervical cancer progression.
Materials And Methods:
The expression of sex-determining region Y-box 2 (SOX2) was tested in four different cervical cancer cell lines, HeLA, SiHa, Caski and C33A. SOX2-expressing SiHa and C33A cell lines were selected for further experiments on the in vitro and in vivo effects of BRM270 on cervical cancer progression using western blotting, flow cytometry, sphere-formation assay, magnetic-activated cell sorting of CD133+ cervical cancer cells, and xenografts in female athymic BALB/c nude mice.
Results:
In the present study, in cervical cancer stem cells (CSCs), we found that BRM270 inhibited expression of SOX2, which is associated with cervical cancer initiation and metastasis. BRM270 also inhibited CD133 expression and induced apoptosis of CSCs and suppressed CD133+ CSC proliferation and sphere formation in vitro as well as SiHa and C33A cell xenograft tumor growth in vivo. This was accompanied by down-regulation of markers of epithelial-to-mesenchymal transition.
Conclusion:
BRM270 might be an effective agent for cervical cancer treatment.
Insights
BRM270, a plant extract, effectively inhibits cervical cancer progression by targeting SOX2 and CD133 expression in cancer stem cells. This formulation demonstrates therapeutic potential by reducing proliferation and tumor growth in vitro and in vivo.
Area of Science:
- Oncology
- Plant-derived therapeutics
- Cancer stem cell biology
Background:
- Cervical cancer remains a significant global health challenge for women.
- BRM270, a plant extract formulation, exhibits potential anticancer properties by inhibiting cell proliferation and CD133 expression in cancer stem cells.
- Sex-determining region Y-box 2 (SOX2) is implicated in cervical cancer initiation and metastasis.
Purpose of the Study:
- To evaluate the therapeutic efficacy of BRM270 against cervical cancer progression.
- To investigate the effects of BRM270 on SOX2 and CD133 expression in cervical cancer cells.
- To assess the in vitro and in vivo impact of BRM270 on cervical cancer stem cells (CSCs).
Main Methods:
- Tested SOX2 expression in HeLa, SiHa, Caski, and C33A cervical cancer cell lines.
- Selected SOX2-expressing SiHa and C33A cells for in vitro and in vivo experiments.
- Utilized western blotting, flow cytometry, sphere formation assays, magnetic-activated cell sorting for CD133+ cells, and xenografts in nude mice.
Main Results:
- BRM270 inhibited SOX2 expression in cervical cancer stem cells (CSCs).
- BRM270 suppressed CD133 expression, induced CSC apoptosis, and inhibited proliferation and sphere formation in vitro.
- BRM270 suppressed xenograft tumor growth in vivo and downregulated epithelial-to-mesenchymal transition markers.
Conclusions:
- BRM270 demonstrates significant therapeutic potential for cervical cancer treatment.
- BRM270 effectively targets key markers (SOX2, CD133) involved in cervical cancer progression.
- Further research into BRM270 as a cervical cancer therapeutic agent is warranted.
