1. Endotoxin induces a shock-like syndrome with increased nitric oxide synthesis. To clarify the cellular source of NO in endotoxic shock we used immunohistochemistry and in situ hybridization to localize inducible NO synthase in rats given lipopolysaccharide or Corynebacterium parvum and lipopolysaccharide. Immunohistochemistry was carried out with an antibody raised against a synthetic peptide of mouse macrophage NO synthase. In situ hybridization was performed with 35S-labelled oligonucleotide probes corresponding to cDNA sequences common to mouse macrophage inducible NO synthase and rat vascular smooth inducible NO synthase. Monocytes and macrophages were identified by immunohistochemistry with the mouse monoclonal antibody ED1. 2. After lipopolysaccharide alone, the major site of NO synthase induction was monocytes and macrophages in multiple organs, principally liver and spleen. Bronchial, bile duct, intestinal and bladder epithelium and some hepatocytes also expressed inducible NO synthase. Expression peaked at 5 h and had returned to normal by 12 h except in spleen. 3. After priming with C. parvum, lipopolysaccharide led to a similar distribution of inducible NO synthase as lipopolysaccharide alone, but in addition there was more prominent hepatocyte staining, staining in macrophage granulomas in the liver and inducible NO synthase was present in some endothelial cells in the aorta. 4. These findings provide a direct demonstration of the cellular localization of inducible NO synthase after lipopolysaccharide.

The sites of synthesis of transthyretin in the brain were investigated using in situ hybridization with [35S]-labeled recombinant cDNA probes specific for transthyretin mRNA. Autoradiography of hybridized coronal sections of rat brain revealed specific cellular localization of transthyretin mRNA in choroid plexus epithelial cells of the lateral, third, and fourth ventricles. Transferrin mRNA was also investigated and, in contrast to transthyretin mRNA, was localized mainly in the lateral ventricles. Our results indicate that substantial synthesis of transthyretin and transferrin mRNA may occur in the choroid plexus.

ABSTRACT Progesterone-associated endometrial protein (PAEP) has been isolated from human decidualized endometrium. In-situ hybridization histochemistry was employed to determine the cellular localization of PAEP mRNA in decidua during pregnancy. PAEP mRNA was found to be expressed in the glandular epithelium of decidua spongiosa throughout pregnancy. Substantial variations in the amount of PAEP mRNA during the course of pregnancy were observed, and it was most abundant at the end of the first trimester. We also found that the PAEP gene was expressed in endometriosis and in a borderline endometrioid adenoma. As in decidual tissues, PAEP mRNA in endometriosis was abundant in the glandular compartment.

Cytochrome P-45017 alpha catalyzes both 17 alpha-hydroxylation and 17,20-side-chain cleavage in steroidogenesis and lies at a key branch point in the pathways of steroid hormone biosynthesis. To obtain information on the precise localization of P-45017 alpha in swine testis, ovary, and adrenal, we undertook the simultaneous detection of P-45017 alpha mRNA and protein by combining immunohistochemistry with in situ hybridization. In situ hybridization was performed on 4% paraformaldehyde-fixed, paraffin-embedded sections by employing either a 39-base oligomer or a cDNA insert (1.7 KB) of porcine testis P-45017 alpha as DNA probe. Immunohistochemical study was performed by employing anti-P-45017 alpha. Hybridization signals were obtained in Leydig cells of the testis, theca interna of the ovarian follicle, and zona fasciculata reticularis cells of the adrenal cortex. Oligonucleotide probing yielded lower background signal than the cDNA probe. No specific signals were obtained in seminiferous tubules of the testis, medulla, and zona glomerulosa of the adrenal, and in membrana granulosa and interstitial cells of the ovary. Hybridization signals were obtained in the cells where immunoreactivity of the enzyme was observed by immunohistochemistry, except for some Leydig cells of the testis and theca interna cells of the ovary in which only immunoreactivity but not hybridization signal was observed. The present study provided detailed information about the precise cellular localization of P-45017 alpha expression at both the protein and mRNA levels in swine adrenal glands and gonads. This approach of simultaneous immunohistochemistry and in situ hybridization analysis of steroidogenic enzymes can be applied in the future to tissues exhibiting abnormal steroid metabolism and should contribute to a better understanding of steroidogenesis.
