The anoxia-dependent elevation of cytosolic Ca(2+) concentration, [Ca(2+)](cyt), was investigated in plants differing in tolerance to hypoxia. The [Ca(2+)](cyt) was measured by fluorescence microscopy in single protoplasts loaded with the calcium-fluoroprobe Fura 2-AM. Imposition of anoxia led to a fast

Transient receptor potential channels (TRPs) regulate tumor growth via calcium-dependent mechanisms. The (thermosensitive) capsaicin receptor TRPV1 is overexpressed in numerous highly aggressive cancers. TRPV1 has potent antiproliferative activity and is therefore potentially applicable in targeted therapy of malignancies. Recently, we
