Polyunsaturated free fatty acids (PUFAs) of both w-3 and w-6 series, induce a rapid increase of cytosolic free Ca2+ concentration ([Ca2+]i) in a leukemic T-cell line (JURKAT), measured by the fluorescent indicator fura-2. The early increase in [Ca2+]i was transient, falling to a sustained level which returned to base line after 10-15 min. In Ca2+-free medium, PUFAs still caused an early increase in [Ca2+]i but rapidly returned to basal. Depletion of endoplasmic reticular Ca2+ pool by addition… CONTINUE READING
