Pterostilbene (PT) extracted from blueberries dose-dependently reduced the enrichment of CD133(+) Mahlavu cells upon irradiation; PT treatment also prevented tumour sphere formation, reduced stemness gene expression, and suppressed invasion and migration abilities as well as increasing apoptosis of CD133(+) Mahlavu CSCs.



Pterostilbene, a bioactive component of blueberries, suppresses the generation of breast cancer stem cells within tumor microenvironment and metastasis via modulating NF-κB/microRNA 448 circuit.

PT effectively suppresses the generation of CSCs and metastatic potential under the influence of M2 TAMs via modulating EMT associated signalling pathways, specifically NF-κB/miR488 circuit. Thus, PT could be an ideal anti-CSC agent in clinical settings
