Ionomycin calcium salt is a narrow spectrum antibiotic being active against Gram-positive bacteria, which produced by the bacterium Streptomyces conglobatus[1]. Ionomycin calcium salt promotes apoptosis. Ionomycin also induces the activation of protein kinase C (PKC)[2].
In vitro, treatment with 2 µM Ionomycin in LCLC 103H cells results in an instantaneous increase in intracellular Ca2+ concentration from 50 to 180 nM. And in Ionomycin-treated cultures, there is obvious DNA fragmentation and PARP cleavage to an 85-kDa fragment, and necrosis could be detected in ~1-5% of the Ionomycin treated cells[2]. In ras oncogene expressing cells, Ionomycin leads to a dose dependent increase of intracellular calcium activity. At 100 nmol/l ionomycin intracellular calcium is increased from 114 ± 17 nmol/l to 342 ± 24 nmol/l, a value within the range of intracellular calcium concentrations following application of bradykinin[3].
In vivo efficacy test, treatment with 1 µm ionomycin for 6 h, ubiquitination of ENaC-β was robustly enhanced in cells overexpressing wild-type Nedd4-2a[4].

Protocol
| Cell experiment [1]: | |
|
Cell lines |
N1E-115 cells |
|
Preparation Method |
Cells were treated with various concentrations (0, 0.2, 0.5, 1, 2, and 10 µM) and incubation times (3, 6, 12, and 24 h) of ionomycin, and cell survival was determined using the trypan blue dye exclusion assay. |
|
Reaction Conditions |
0, 0.2, 0.5, 1, 2, and 10 µM；3, 6, 12, and 24 h |
|
Applications |
Ionomycin treatment induced cell death in a concentration- and time-dependent manner. |
| Animal experiment [2]: | |
|
Animal models |
Adult male C57BL/6 wild type (20-25 g, 8-10 weeks old) and FXR KO mice (20-25 g, 8-10 weeks old) |
|
Preparation Method |
In order to investigate the biological function of FXR in vivo, an L-type calcium channel agonist, Bayk8644 (2 mg/kg) was given intraperitoneally at 10 min after reperfusion. Bayk8644 stock solution (1 mmol/L in dimethyl sulfoxide, DMSO) was diluted in 1× phosphate-buffered saline (PBS) with a final DMSO concentration of 4.6%. Similarly, PBS with 4.6% DMSO was given intraperitoneally in sham, wild-type vehicle, and FXR knockout vehicle groups as control. A dose range of ionomycin (50 nmol/L), GW4064 (0, 1, 1.5, 3, and 6 µmol/L), or Z-guggulsterone (Z-GS, 0, 2.5, 5, and 10 µmol/L) was given for 18 h before oxygen and glucose deprivation (OGD). |
|
Dosage form |
50 nmol/L (4.6% DMSO); 18 h; i.p. |
|
Applications |
TUNEL staining demonstrated that Z-GS treatment reduced neuronal apoptosis and addition of IM (Ionomycin) significantly increased apoptotic neurons compared to OGD group, suggesting that inhibition of FXR (Farnesoid X receptor) can reduce neuronal apoptosis through reducing calcium influx after OGD/R. |
