The integration of growth and the acute-phase response is investigated by comparing the mRNA levels in rat liver during acute inflammation with those after partial hepatectomy. Northern analysis is carried out for the mRNAs for thiostatin, alpha 2-macroglobulin, alpha 1-antitrypsin, inter-alpha-trypsin inhibitor subunit 1, haptoglobin, ceruloplasmin, transferrin, vitamin D-binding protein, alpha 1-acid glycoprotein, beta-fibrinogen, apolipoproteins A-IV and E, albumin, transthyretin, alpha 2-HS-glycoprotein, retinol-binding protein, beta-tubulin, c-myc protooncogene, glyceraldehyde-3-phosphate dehydrogenase, phosphoenolpyruvate carboxykinase, ornithine transcarbamylase, and alcohol dehydrogenase. The acute-phase response dominates during the first 18 h. Changes in mRNA levels related to growth of the liver become important thereafter, and the capacity for an acute-phase response of plasma protein synthesis becomes greatly reduced. The early increase in the level of ceruloplasmin mRNA observed during inflammation is abolished during regeneration, and that of vitamin D-binding protein mRNA is converted into a decrease. The mRNAs levels of glyceraldehyde-3-phosphate dehydrogenase increase, and those for phosphoenolpyruvate carboxykinase decrease during regeneration. Ornithine transcarbamylase mRNA levels are found to exhibit negative acute-phase regulation. The pattern of transcriptional regulation is similar during inflammation and regeneration.

Dietary copper (Cu) restriction causes a hypertrophic cardiomyopathy similar to that induced by work overload in rodent models. However, a possible change in the program of hypertrophic gene expression has not been studied in the Cu-deficient heart. This study was undertaken to fill that gap. Dams of mouse pups were fed a Cu-deficient diet (0.35 mg/kg diet) or a Cu-adequate control diet (6.10 mg/kg) on the fourth day after birth, and weanling mice continued on the dams' diet until they were sacrificed. After 5 weeks of feeding, Cu concentrations were dramatically decreased in the heart and the liver of the mice fed the Cu-deficient diet. Corresponding to these changes, serum ceruloplasmin concentrations and hepatic Cu,Zn-superoxide dismutase activities were significantly (P<0.05) depressed. The size of the Cu-deficient hearts was greatly enlarged as estimated from the absolute heart weight and the ratio of heart weight to body weight. The abundances of mRNAs for atrial natriuretic factor, beta-myosin heavy chain, and alpha-skeletal actin in left ventricles were all significantly increased in the Cu- deficient hearts. Furthermore, Cu deficiency activated the expression of the c-myc oncogene in the left ventricle. This study thus demonstrated that a molecular program of alterations in embryonic genes, similar to that shown in the work-overloaded heart, was activated in the hypertrophied heart induced by Cu deficiency.
