Abstract EN
Several researches revealed that propofol, a hypnotic intravenous anesthesia agent, could inhibit the cancer cell proliferation and tumor formation, which might affect cancer recurrence or metastasis and impact patients’ prognosis.
Cancer stem cells (CSCs) comprised a tiny fraction of tumor bulk and played a vital role in cancer recurrence and eventual mortality.
This study investigates the effect of propofol on breast cancer stem cells (BCSCs) in vitro and the underlying molecular mechanisms.
Tumor formation of CSCs was measured by mammosphere culture.
Cultured BCSCs were exposed to different concentrations and durations of propofol.
Cell proliferation and self-renewal capacity were determined by MTT assays.
Expressions of PD-L1 and Nanog were measured using western blotting and real-time PCR.
We knocked down the PD-L1 expression in MDA-MB-231 cells by lentivirus-mediated RNAi technique, and the mammosphere-forming ability of shControl and shPD-L1 under propofol treatment was examined.
Mammosphere culture could enrich BCSCs.
Compared with control, cells exposed to propofol for 24 h induced a larger number of mammosphere cells (P=0.0072).
Levels of PD-L1 and Nanog were downregulated by propofol.
Compared with shControl stem cells, there was no significant difference in the inhibitory effect of propofol on the mammosphere-forming ability of shPD-L1 stem cells which indicated that the inhibition of propofol could disappear in PD-L1 knockdown breast stem cells.
Propofol could reduce the mammosphere-forming ability of BCSCs in vitro.
Mechanism experiments indicated that the inhibition of propofol in mammosphere formation of BCSCs might be mediated through PD-L1, which was important to maintain Nanog.
