“…In accordance with this view, the primary effect of parathyroid hormone is on the cellular accumulation and transport of calcium and phosphate in a variety of tissues. Although the movement of calcium ions across membranes requires the additional presence of vitamin D, the translocation of inorganic phosphate is dependent solely upon parathyroid hormone (Rasmussen & DeLuca, 1963).…”

“…In vitro binding of calcium to mitochondria also has been observed (Slater and Cleland, 1953;DeLuca and Engstrom, 1961 ;Vasington and Murphy, 1962;Lehninger et al, 1963;Brierley et al, 1963;Engstrom and DeLuca, 1964). Digitonin-treated mitochondria bind calcium (Vasington, 1963); vitamin D and parathyroid hormone influence mitochondrial calcium binding (DeLuca et al, 1962;Rasmussen and DeLuca, 1963); and carbon tetrachloride (Thiers et al, 1960) and thioacetamide (Gallagher et al, 1956) cause mitochondrial calcium to increase markedly.…”

The intracellular distribution of calcium has been studied in the mucosa of the avian shell gland, a tissue which transports large quantities of calcium during discrete time intervals. Ca ~ was administered to hens either in a single dose followed by sacrifice 5 min later or in repeated doses over an extended period followed by sacrifice 2 hr or 24 hr after the last injection. Subcellular fractions were isolated by differential centrifugation and analyzed for Ca 45. The Ca 4~ was located principally in the particulate fractions; the concentration (CPM Ca45/mg N) was highest in the mitochondrial fraction. Comparisons of (1) the Ca 4~ distribution in shell gland cells with that of liver cells, (2) the alterations which occur due to the phase of the egg laying cycle, (3) the effects due to the time elapsed since the last injection of Ca ~, and (4) the Ca 45 distribution of the short term experiments with that of the long term experiments revealed that the mitochondrial fraction of the shell gland appeared to be active in the movement of calcium. The microsomal fraction showed increased values in cv~ Ca~/mg N when calcification was occurring, which may indicate that the subcellular components of this fraction have a role in calcium transport. The nuclear and supernatant fractions did not seem to be involved in the transport process. The implications of these. results concerning the manner by which calcium may be controlled on a cellular level in this system are discussed.
