Information from the abstract
Breast cancer is one of the most prevalent malignancies among women worldwide; its incidence and mortality are expected to increase annually.Cancer is composed not only malignant cells but also a complex and dynamic network of interacting stromal cells, specifically immune cells, which contribute to tumor development and progression.Increasing evidence highlights the critical role of tumor-associated macrophages (TAMs) and their inflammasome-driven signaling pathways in tumor progression and therapeutic resistance.Curcumin, a natural compound with anti-carcinogenic potential, has a role in the regulation of cancer development and progression.However, its specific effects on inflammasome activation in TAMs within the tumor microenvironment (TME) remain insufficiently characterized.THP-1 monocytes differentiated into macrophages acquire the TAM-like phenotype when treated with conditioned media from breast cancer cells.Our present study aimed to investigate the effects of curcumin on inflammasome activation in macrophages induced by breast cancer-derived conditioned media.Breast cancer-derived conditioned media stimulation induced manifestation of a pro-inflammatory TAM-like phenotype, characterized by increased interleukin (IL)-1β secretion and upregulation of NOD-like receptor protein 3 (NLRP3), caspase-1, and IL-1β.Curcumin pretreatment significantly reduced IL-1β secretion as well as NLRP3 protein levels.Moreover, it also suppressed IL1B and CASP1 mRNA expression.In conclusion, curcumin attenuates tumor-induced inflammasome activation, highlighting its potential to modulate TME-driven breast cancer progression via the NLRP3/caspase-1/IL-1β axis.
