Cancer stem cells (CSCs) constitute a subpopulation of transformed cells that possess intrinsic ability to undergo self-renewal and differentiation, which drive tumor resistance and cancer recurrence. It has been reported that CSCs possess enhanced protection against oxidative stress induced by reactive oxygen species compared with non-stem-like cancer cells. In the present work, we investigated the role of heme oxygenase-1 (HO-1), a representative antioxidant enzyme, on the stemness and self-renewal of human breast CSCs. We found that pharmacologic or genetic inhibition of HO-1 attenuated the sphere formation, whereas HO-1 inducers enhanced the number and the size of tumorspheres in breast CSCs. Carbon monoxide (CO) is endogenously generated as a consequence of degradation of heme by HO-1. The proportion of populations of CD44+/CD24- cells retaining CSC properties was increased in MDA-MB-231 cells treated with a CO-releasing molecule (CORM-2). Following CORM-2 treatment, the expression of Notch-1 and related genes Jagged-1 and Hes-1 was increased, which was accompanied by the mammosphere formation. Taken together, these findings suggest that HO-1-derived CO production stimulates the formation of mammospheres in breast cancer cells through activation of Notch-1 signaling.

Poster Panel Size
Please refer to this visualization of the poster panels to be used during the conference. The display area for each poster on the panel of the poster board is 90 cm wide X120 cm long. Please ensure that your poster does not exceed this size. It is recommended that you leave a margin of at least 3 inches (7.5 cm) around the poster. When preparing your poster and considering how much of your display will be visible at eye-level, please bear in mind that panels will be mounted on stands.
Poster Panel Allocation
A numbered panel will be allocated for each poster (separate from the abstract number you have been assigned) and staffs will be on hand at the conference to provide your poster panel number. Please ensure that you stand by your poster(s) during your session for discussion and questions.
