SIRT1 Promotes Breast Cancer Stem Cell-Associated Properties and Represents a Potential Therapeutic Target
Breast cancer stem cells (BCSCs) drive tumor progression, metastasis, and therapeutic resistance. Sirtuin 1 (SIRT1) has been implicated in stem cell regulation, but its context-dependent role in BCSC maintenance and the underlying molecular mechanisms remain poorly defined. SIRT1 expression was evaluated in human breas...
