Control of VX2 carcinoma cell growth in culture by calcium, calmodulin, and prostaglandins.

Based on our in vivo observation that growth of VX2 carcinoma transplanted in rabbits paralleled development of hypercalcemia, we studied the regulation of VX2 tumor growth using a clonal cell line isolated from VX2 tumor (VX2-L). VX2-L cell growth was dependent on prostaglandins released by the cultured cells into the medium, since indomethacin suppressed… CONTINUE READING
