Abstract (original English)
Introduction: Breast cancer ranks among the most prevalent malignancies, and its prompt diagnosis significantly amplifies the prospects of successful treatment. Approximately one in seven women will experience a breast cancer diagnosis in their lifetime. Stromal cells and their secreted factors exert various effects on tumor growth, impacting proliferation, invasion, and metastasis. Research has emphasized the significant impact of proteins secreted by adipose tissue on breast cancer proliferation, surpassing the influence of factors released by other cell types. Yet, the specific transcription factors and cofactors involved in adipokine expression in the tumor microenvironment remain enigmatic. Methods: In this study, adipocyte cells were cultured and exposed to 980 nm and 650 nm Photobiomodulation. The MDA-MD-231 cells (triple negative cancer cell line) were cultured with a conditioned medium from laser-treated cells. The real-time assay was employed to analyze the gene expression level changes involved in apoptosis. Results: Results showed that the irradiated conditioned medium at 980 nm and 650 nm caused a reduction in cell viability of cancer cells. Conversely, the conditioned medium from the irradiated cells triggered an increase in the expression of Caspase 3 , Caspase 9 , and BAX2 genes, alongside a decrease in BCL2 gene expression. Conclusion: The findings highlighted
