Leptin plays an important role in appetite and energy regulation via signaling through melanocortin receptors (MCRs) in the brain. As serum levels of MCR ligands are elevated in a clinical situation [acute-phase response (APR)] to tissue damage, where the liver is responsible for the metabolic changes, we studied hepatic gene expression of MCRs in a model of muscle tissue damage induced by turpentine oil (TO) injection in rats. A significant increase in gene expression of all five MCRs (MC4R was the highest) in liver at the RNA and protein level was detected after TO injection. A similar pattern of increase was also found in the brain. Immunohistology showed MC4R in the cytoplasm, but also in the nucleus of parenchymal and non-parenchymal liver cells, whereas MC3R-positivity was mainly cytoplasmic. A time-dependent migration of MC4R protein from the cytoplasm into the nucleus was observed during APR, in parallel with an increase in alpha-MSH and leptin serum levels. An increase of MC4R was detected at the protein level in wild-type mice, while such an increase was not observed in IL-6ko mice during APR. Moreover, treatment of isolated liver cells with melanocortin agonists (alpha-MSH and THIQ) inhibited the endotoxin-induced upregulation of the acute-phase cytokine (IL-6, IL1 beta and TNF-alpha) gene expression in Kupffer cells and of chemokine gene expression in hepatocytes. MCRs are expressed not only in the brain, but also in liver cells and their gene expression in liver and brain tissue is upregulated during APR. Due to the presence of specific ligands in the serum, they may mediate metabolic changes and exert a protective effect on liver cells."],["dc.identifier.doi","10.1007/s00418-011-0899-7"],["dc.identifier.isi","000300326100002"],["dc.identifier.pmid","22183812"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7321"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/27120"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0948-6143"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Melanocortin receptors in rat liver cells: change of gene expression and intracellular localization during acute-phase response"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2019Journal Article [["dc.bibliographiccitation.firstpage","1"],["dc.bibliographiccitation.journal","Journal of Cellular and Molecular Medicine"],["dc.bibliographiccitation.lastpage","9"],["dc.contributor.author","Malik, Gesa"],["dc.contributor.author","Wilting, Jörg"],["dc.contributor.author","Hess, Clemens Friedrich"],["dc.contributor.author","Ramadori, Giuliano"],["dc.contributor.author","Malik, Ihtzaz Ahmed"],["dc.date.accessioned","2019-07-09T11:50:04Z"],["dc.date.available","2019-07-09T11:50:04Z"],["dc.date.issued","2019"],["dc.description.abstract","The mechanisms of radiation-induced liver damage are poorly understood. We investigated if tumour necrosis factor (TNF)-α acts synergistically with irradiation, and how its activity is influenced by platelet endothelial cell adhesion molecule-1 (PECAM-1). We studied murine models of selective single-dose (25 Gy) liver irradiation with and without TNF-α application (2 μg/mouse; i.p.). In serum of wild-type (wt)-mice, irradiation induced a mild increase in hepatic damage marker aspartate aminotransferase (AST) in comparison to sham-irradiated controls. AST levels further increased in mice treated with both irradiation and TNF-α. Accordingly, elevated numbers of leucocytes and increased expression of the macrophage marker CD68 were observed in the liver of these mice. In parallel to hepatic damage, a consecutive decrease in expression of hepatic PECAM-1 was found in mice that received radiation or TNF-α treatment alone. The combination of radiation and TNF-α induced an additional significant decline of PECAM-1. Furthermore, increased expression of hepatic lipocalin-2 (LCN-2), a hepatoprotective protein, was detected at mRNA and protein levels after irradiation or TNF-α treatment alone and the combination of both. Signal transducer and activator of transcription-3 (STAT-3) seems to be involved in the signalling cascade. To study the involvement of PECAM-1 in hepatic damage more deeply, the liver of both wt- and PECAM-1-knock-out-mice were selectively irradiated (25 Gy). Thereby, ko-mice showed higher liver damage as revealed by elevated AST levels, but also increased hepatoprotective LCN-2 expression. Our studies show that TNF-α has a pivotal role in radiation-induced hepatic damage. It acts in concert with irradiation and its activity is modulated by PECAM-1, which mediates pro- and anti-inflammatory signalling."],["dc.identifier.doi","10.1111/jcmm.14224"],["dc.identifier.pmid","30761739"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15851"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59695"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1582-4934"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.ddc","610"],["dc.title","PECAM-1 modulates liver damage induced by synergistic effects of TNF-α and irradiation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI PMID PMC2013Journal Article [["dc.bibliographiccitation.firstpage","321"],["dc.bibliographiccitation.issue","3"],["dc.bibliographiccitation.journal","Radiation and Environmental Biophysics"],["dc.bibliographiccitation.lastpage","338"],["dc.bibliographiccitation.volume","52"],["dc.contributor.author","Rave-Fraenk, Margret"],["dc.contributor.author","Malik, Ihtzaz Ahmed"],["dc.contributor.author","Christiansen, Hans"],["dc.contributor.author","Naz, Naila"],["dc.contributor.author","Sultan, Sadaf"],["dc.contributor.author","Amanzada, Ahmad"],["dc.contributor.author","Blaschke, Martina"],["dc.contributor.author","Cameron, Silke"],["dc.contributor.author","Ahmad, Shakil"],["dc.contributor.author","Hess, Clemens Friedrich"],["dc.contributor.author","Ramadori, Giuliano"],["dc.contributor.author","Moriconi, Federico"],["dc.date.accessioned","2018-11-07T09:22:03Z"],["dc.date.available","2018-11-07T09:22:03Z"],["dc.date.issued","2013"],["dc.description.abstract","The liver is considered a radiosensitive organ.

Rats were exposed to selective liver FI (total dose 60 Gy, 2 Gy/day) or HDI (25 Gy) and were killed three months after the end of irradiation. To study acute effects, HDI-treated rats were additionally killed at several time points between 1 and 48 h. Three months after irradiation, no differences between FI and HDI treatment were found for macroscopically detectable small \"scars\" on the liver surface and for an increased number of neutrophil granulocytes distributed in the portal fields and through the liver parenchyma. As well, no changes in HE-stained tissues or clear signs of fibrosis were found around the portal vessels. Differences were seen for the number of bile ducts being increased in FI- but not in HDI-treated livers. Serum levels indicative of liver damage were determined for alkaline phosphatase (AP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (gamma GT) and lactate dehydrogenase (LDH).

We investigated hepatic gene expression of CXC- and CC-chemokines in a model of a localized extrahepatic aseptic abscess and in a model of septicemia produced by the intramuscular injection of turpentine oil (TO) into each hindlimb or lipopolysaccharide (LPS) intraperitoneally (i.p.) in rats and mice (wild-type (WT) and IL6-KO).

The induction of the gene expression of CXCL1 and CXCL8 was the fastest and strongest. The hepatic CXC-chemokines behaved like positive APPs that depend on IL6 production by activated macrophages recruited to extrahepatic damaged tissue.

METHODS Rats received intraperitoneal injection of the hepatotoxin thioacetamide (TAA), and were sacrificed regularly between 1 and 96 h thereafter. Serum levels of transaminases and iron were measured using conventional laboratory assays. Liver tissue was used for conventional histology, immunohistology, and iron staining. The expression of acute-phase cytokines, ferritin light chain (FTL), and ferritin heavy chain (FTH) was investigated in the liver by qRT-PCR. Western blotting was used to investigate FTL and FTH in liver tissue and serum. Liver and spleen tissue was also used to determine iron concentrations. RESULTS After a short initial decrease, iron serum concentrations increased in parallel with serum transaminase (aspartate aminotransferase and alanine aminotransferase) levels, which reached a maximum at 48 h, and decreased thereafter. Similarly, after 48 h a significant increase in FTL, and after 72h in FTH was detected in serum. While earliest morphological signs of inflammation in liver were visible after 6 h, increased expression of the two acute-phase cytokines IFN-γ (1h) and IL-1β (3h) was detectable earlier, with maximum values after 12-24 h. Iron concentrations in liver tissue increased steadily between 1 h and 48 h, and remained high at 96 h. In contrast, spleen iron concentrations remained unchanged until 48 h, and increased mildly thereafter (96 h). Although tissue iron staining was negative, hepatic FTL and FTH protein levels were strongly elevated. Our results reveal effects on hepatic iron concentrations after direct liver injury by TAA. The increase of liver iron concentrations may be due to the uptake of a significant proportion of the metal by healthy hepatocytes, and only to a minor extent by macrophages, as spleen iron concentrations do not increase in parallel. The temporary increase of iron, FTH and transaminases in serum is obviously due to their release by damaged hepatocytes. CONCLUSION Increased liver iron levels may be the consequence of hepatocyte damage. Iron released into serum by damaged hepatocytes is obviously transported back and stored via ferritins."],["dc.identifier.doi","10.3748/wjg.v23.i41.7347"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14835"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59046"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","2219-2840"],["dc.rights","CC BY-NC 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc/4.0"],["dc.subject.ddc","610"],["dc.title","Reabsorption of iron into acutely damaged rat liver: A role for ferritins"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI2012Journal Article [["dc.bibliographiccitation.firstpage","217"],["dc.bibliographiccitation.issue","2"],["dc.bibliographiccitation.journal","Histochemistry and Cell Biology"],["dc.bibliographiccitation.lastpage","233"],["dc.bibliographiccitation.volume","137"],["dc.contributor.author","Wojcik, Marta"],["dc.contributor.author","Ramadori, Pierluigi"],["dc.contributor.author","Blaschke, Martina"],["dc.contributor.author","Sultan, Sadaf"],["dc.contributor.author","Khan, Sajjad"],["dc.contributor.author","Malik, Ihtzaz Ahmed"],["dc.contributor.author","Naz, Naila"],["dc.contributor.author","Martius, Gesa"],["dc.contributor.author","Ramadori, Giuliano"],["dc.contributor.author","Schultze, Frank Christian"],["dc.date.accessioned","2018-11-07T09:14:07Z"],["dc.date.available","2018-11-07T09:14:07Z"],["dc.date.issued","2012"],["dc.description.abstract","It has been suggested that cyclooxygenase-2 (COX-2)-mediated prostaglandin synthesis is associated with liver inflammation and carcinogenesis.
