Moreover, T. gondii tachyzoites have shown anti-cancer activity in BC mouse models based on MCF7 and MDA-MB-231 cell lines due to the ability to regulate several signaling pathways at the transcriptome level by altering BRCA1, MYC, and IL-6, which are known to inhibit mammary tumor growth and migration [218]. This evidence concerns the gene BRCA1 and cancer.
