Abstract: The present disclosure relates to ‘Jedae mandarin’, a new citrus variety of early-ripening satsuma mandarin. The branch buds of C. unshiu Marc. cv. Miyagawa-wase, an early-maturing satsuma mandarin, underwent gamma irradiation and subsequent grafting for asexual propagation. As a result, the ‘Jedae mandarin’, a novel variety of citrus plant, showed uneven peels of fruits and changes in flavonoid content, compared to C. unshiu Marc. cv. Miyagawa-wase, although it exhibited characteristics very similar to those of C. unshiu Marc. cv. Miyagawa-wase in terms of blooming, fruit-bearing, sugar content, acidity, etc. Thus, ‘Jedae mandarin’ may be used as a new variety with high economic value.

Abstract: The present invention relates to a composition for inhibiting the growth of cancer stem cells, which includes ciclesonide or a pharmaceutically acceptable salt thereof as an active ingredient, a pharmaceutical composition or food composition for inhibiting cancer metastasis, or treating or preventing cancer, which includes the composition, and the like. Ciclesonide of the present invention inhibits the growth of breast cancer cells and lung cancer cells, and inhibits the formation of breast cancer stem cells and lung cancer stem cells.
