Ionophore-mediated calcium exchange diffusion in liposomes [PDF]

, 1980
The exchange diffusion of 45Ca in multilamellar liposomes containing the antibiotic ionophore A23187 is enhanced in a dose-related fashion at increasing concentrations of external Ca2+ or at increasing A23187/lipid molar ratios.

Rediscovering Sodium Ionophores as Selective Agents for Lithium Recognition and Extraction

Angewandte Chemie, EarlyView.
Long‐classified sodium ionophores unexpectedly prefer lithium and act as efficient extractants in solid–liquid extraction (SLE). Readily prepared from catechol and haloacetamides, these hosts recover hydrated LiCl from multicomponent salt mixtures via a hydration‐assisted O···Li+ binding mode, enabling scalable lithium separation with Li/Na, Li/K, and ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
