Dependence of ionophore- and caffeine-induced calcium release from sarcoplasmic reticulum vesicles on external and internal calcium ion concentrations [PDF]

, 1977
The effects of the ionophore, X537A, and caffeine on ATP-dependent calcium transport by fragmented sarcoplasmic reticulum were studied in the absence (calcium storage) or presence (calcium uptake) of calcium-precipitating anions.

Effects of the calcium ionophore A 23187 on low-density lipoprotein processing and lipid metabolism in cultured human fibroblasts [PDF]

, 1984
Pretreatment of cultured human fibroblasts with the calcium ionophore A 23187 resulted in a decrease in low-density lipoprotein internalization. This effect was dose-dependent and did not occur in a medium devoid of calcium.

Rational Design of Crown Ether‐Based Fluorescent Sensors for Group II Cations: Insights From Vibrational Spectroscopy and Computation

ChemPhysChem, Volume 27, Issue 12, 26 June 2026.
We use vibrational spectroscopy to determine the solution phase structures of complexes of two fluorescent sensors with metal ions. We use these to understand differences in the absorption spectra and to explain why even very low levels of water destroy the fluorescent response. Rational design of fluorescent sensors requires knowledge of the molecular

Calcium Ionophore A23187 Induces Interleukin-8 Gene-Expression and Protein Secretion in Human Monocytic Cells [PDF]

, 1993
The regulation of the expression of the interleukin-8 (IL-8) gene in human monocytic cell lines has been investigated. Agents such as interleukin-1 (IL-1) or interferon-gamma (IFNgamma) did not induce increased IL-8 expression in THP-1 or U937 cells ...

Platelet phosphatidylserine exposure and microparticle production as health bioindicators in marine mammals

Frontiers in Veterinary Science
In human medicine, various pathologies, including decompression sickness, thrombocytopenia, and rheumatoid arthritis, have been linked to changes in cellular microparticles (MP) formation, particularly platelet microparticles (PMP).
