Taurine regulation of Ca2+ uptake and (Ca2+ + Mg2+)-ATPase in developing chick B-cells
1993
Porter, D.W. | Martin, G.W.
The objective of the present study was to determine the effect of age and taurine on chick B cell calcium uptake and membrane (Ca(2+) + Mg(2+))-ATPase activity in 1-4-week-old chicks. The calcium uptake rate decreased with age (P < 0.05) and was further decreased by taurine (P < 0.05). (Ca(2+) + Mg(2+))-ATPase activity increased with age (P < 0.05) and was stimulated by taurine (P < 0.05). The data demonstrate that the flux of calcium across the B-cell membrane changes during early post-hatch development, and that taurine regulates both the influx and efflux of calcium in chick B-cells.
