title: [Influence of a rachitogenic regime on hepatic metabolism in the rat].
abstract: We have previously reported that rats fed on the Steenbock and Black's rickets-inducing diet (deficient in vitamin D and with an altered Ca/P ratio) show metabolic modifications in kidney and intestinal mucosa. We have therefore decided to investigate if also in liver, seat of vitamin D hydroxylation, changes in the metabolic pattern occur. An increase of mitochondrial NAD+-dependent isocitrate dehydrogenase and a decrease of citrate and ATP content was demonstrated in liver of rachitic rats, together with changes in ATP-citrate lyase and glucose-6-phosphate dehydrogenase activity. The inhibitory effect of ATP on liver mitochondria NAD+-dependent isocitrate dehydrogenase was also studied.
