Ionomycin calcium salt is a calcium ionophore [1].

Ca2+ ionophore acts as a Ca2+ ionophore, allowing Ca2+ to cross cell membranes.

Ionomycin calcium salt is a calcium ionophore. In cultured chicken pectoralis muscle, ionomycin (10-6-10-5 M) selectively increased the incorporation of methionine into two proteins. Ionomycin increased influx of extracellular Ca2+ and increased Ca2+ concentration in the cytoplasm, which then regulated the synthesis of muscle proteins [2]. In rat parotid gland, ionomycin increased 86Rb efflux, 22Na uptake and 3H-protein secretion, which were dependent on increasing cytosolic Ca2+. In parotid cells, ionomycin released the receptor-regulated cellular Ca2+ pool [3]. In human bladder cancer cells HT1376, ionomycin significantly inhibited cell growth in a time- and dose-dependent way and induced apoptotic DNA degradation. Also, ionomycin reduced the ratios of Bcl-2 to Bax mRNA and protein [4].

In athymic nude mice bearing HT1376 tumors, ionomycin significantly inhibited tumor growth and reduced the tumorigenicity [4].
