We studied the changes in serum fibroblast growth factor-21 (FGF-21) concentrations, its mRNA, and protein expression in skeletal muscle and adipose tissue of 15 patients undergoing cardiac surgery. Blood samples were obtained: prior to initiation of anesthesia, prior to the start of extracorporeal circulation, upon completion of the surgery, and 6, 24, 48, and 96 hours after the end of the surgery. Tissue sampling was performed at the start and end of surgery. The mean baseline serum FGF-21 concentration was 63.1 (43.03-113.95) pg/ml and it increased during surgery with peak 6 hours after its end [385.5 (274.55-761.65) pg/ml, p < 0.001], and returned to baseline value [41.4 (29.15-142.83) pg/ml] 96 hours after the end of the surgery. Serum glucose, insulin, CRP, IL-6, IL-8, MCP-1, and TNF-alpha concentrations significantly increased during the surgery. Baseline FGF-21 mRNA expression in skeletal muscle was higher than in both adipose tissue depots and it was not affected by the surgery. Epicardial fat FGF-21 mRNA increased after surgery. Muscle FGF-21 mRNA positively correlated with blood glucose levels at the end of the surgery. Our data suggest a possible role of FGF-21 in the regulation of glucose metabolism and insulin sensitivity in surgery-related stress.

Resistin is a member of adipokine family involved in the regulation of inflammatory reactions and insulin sensitivity. In presented study its possible role in the development of benign prostate hyperplasia and prostate cancer was evaluated. Blood samples and prostate specimens were collected from 26 patients with benign prostate hyperplasia (BPH) and from 42 patients with prostate cancer (PCa) stage pT2 (n=18) and pT3 (n=24). Selected metabolic and biochemical parameters and serum resistin levels were measured and anthropometric measurements were performed as well as tissue immunohistochemistry for resistin. Serum resistin levels did not differ significantly between benign hyperplasia and prostate cancer but in cancer patients there was a trend towards decrease with higher cancer stage. Moreover, serum resistin levels were significantly lower in patients with seminal vesicle invasion in comparison to those without invasion. While in BPH serum resistin levels correlated with insulin resistance, inflammatory status and cortisol, in PCa positive correlation with F/T PSA ratio and cortisol was observed. Tissue immunohistochemistry did not show any differences in staining pattern between benign and neoplastic prostate tissue. We conclude that serum resistin levels do not significantly differ between patients with benign prostate hyperplasia and prostate cancer, but there is a trend towards decrease in resistin serum levels in advanced cancer cases.

Serum levels of adiponectin were measured in patients with benign prostatic hyperplasia and prostate cancer of pT2 and pT3 stage. Adiponectin ELISA assay, immunohistochemistry, and selected metabolic and biochemical parameters measurement was performed in 25 patients with benign prostatic hyperplasia and 43 with prostate cancer (17 patients with organ-confined and 26 patients with locally advanced disease). Serum adiponectin levels did not differ between prostate benign hyperplasia and cancer clinical stage T2, but was significantly higher in pT3 relative to pT2 group (14.51+/-4.92 vs. 21.41+/-8.12, P = 0.003). Tissue immunohistochemistry showed enhanced staining in neoplastic prostate glands and intraepithelial neoplasia relative to benign prostatic hyperplasia without distinction between disease grade and stage. Serum adiponectin levels are higher in locally advanced relative to organ-confined prostate cancer and may thus serve as an auxiliary marker providing further improvement for discrimination between pT2 and pT3 stages.

BACKGROUND: Resistin is a newly identified adipocytokine which has demonstrated links between obesity and insulin resistance in rodents. In humans, proinflammatory properties of resistin are superior to its insulin resistance-inducing effects. OBJECTIVES: To assess resistin expression in synovial tissues, serum and synovial fluid from patients with rheumatoid arthritis, osteoarthritis and spondylarthropathies (SpA), and to study its relationship with inflammatory status and rheumatoid arthritis disease activity. METHODS: Resistin expression and localisation in synovial tissue was determined by immunohistochemistry and confocal microscopy. Serum and synovial fluid resistin, leptin, interleukin (IL)1beta, IL6, IL8, tumour necrosis factor alpha, and monocyte chemoattractant protein-1 levels were measured. The clinical activity of patients with rheumatoid arthritis was assessed according to the 28 joint count Disease Activity Score (DAS28). RESULTS: Resistin was detected in the synovium in both rheumatoid arthritis and osteoarthritis. Staining in the sublining layer was more intensive in patients with rheumatoid arthritis compared with those with osteoarthritis. In rheumatoid arthritis, macrophages (CD68), B lymphocytes (CD20) and plasma cells (CD138) but not T lymphocytes (CD3) showed colocalisation with resistin. Synovial fluid resistin was higher in patients with rheumatoid arthritis than in those with SpA or osteoarthritis (both p<0.001). In patients with rheumatoid arthritis and SpA, serum resistin levels were higher than those with osteoarthritis (p<0.01). Increased serum resistin in patients with rheumatoid arthritis correlated with both CRP (r=0.53, p<0.02), and DAS28 (r=0.44, p<0.05), but not with selected (adipo) cytokines. CONCLUSION: The upregulated resistin at local sites of inflammation and the link between serum resistin, inflammation and disease activity suggest a role for resistin in the pathogenesis of rheumatoid arthritis.

"Proteinase-activated" receptor-2 (PAR-2) is a G protein-coupled transmembrane receptor with seven transmembrane domains activated by trypsin. It has been shown in the pancreatic tissue that PAR-2 is involved in duct/acinary cells secretion, arterial tonus regulation and capillary liquid content turnover under physiological conditions. These above mentioned structures play an important role during the development of acute pancreatitis and are profoundly influenced by a high concentration of trypsin enzyme after its secretion into the interstitial tissue from the basolateral aspect of acinar cells. Among the other factors, it is the increase of interstitial trypsin concentration followed rapidly by PAR-2 action on pancreatic vascular smooth muscle cells that initiates ischemic changes in pancreatic parenchyma and that finally leads to necrosis of the pancreas. Consequent reperfusion perpetuates changes leading to the acute pancreatitis development. On the contrary, PAR-2 action on both exocrine and duct structures seems to play locally a protective role during acute pancreatitis development. Moreover, PAR-2 action is not confined to the pancreas but it contributes to the systemic vascular endothelium and immune cell activation that triggers the systemic inflammatory response syndrome (SIRS) contributing to an early high mortality rate in severe disease.

Adipose tissue-produced hormones significantly affect the metabolism of lipids and carbohydrates as well as numerous other processes in human body. It is generally accepted that endocrine dysfunction of adipose tissue may represent one of the causal links between obesity and insulin resistance/diabetes. Epidemiological studies underlined that obesity represents a significant risk factor for the development of cancer, although the exact mechanism of this relationship remains to be determined. Multiple recent studies have indicated that some of adipose tissue-derived hormones may significantly influence the growth and proliferation of tumorous stroma and malignant cells within. Here we review current knowledge about possible relationship of leptin and adiponectin to the etiopathogenesis of different malignant tumors. Most of the studies indicated that while leptin may potentiate the growth of cancer cells in vitro, adiponectin appears to have an opposite effect. Further studies are necessary to decide whether obesity-induced endocrine dysfunction of adipose tissue can directly influence carcinogenesis in different tissues and organs.

Adiponectin has been shown to exert insulin-sensitizing, anti-atherogenic, and anti-inflammatory properties in metabolic diseases. It has been suggested that adiponectin may play a role in rheumatoid arthritis (RA). To assess adiponectin in serum and synovial fluid from patients with RA and osteoarthritis (OA), and in serum from healthy controls. Adiponectin and CRP levels were analyzed by ELISA. The clinical activity of RA patients was assessed according to the 28 joint count Disease Activity Score. Synovial fluid adiponectin was significantly higher in RA than in OA patients (p<0.001). Adiponectin was negatively associated with the leukocyte count in RA synovial fluid (r=-0.45, p<0.05). Serum adiponectin was higher in RA compared to healthy controls (p<0.02), however comparable to OA patients. Serum adiponectin was higher than in synovial fluid in both diseases (p<0.001). In general, women had higher adiponectin levels than men. Adiponectin was not related to age, disease duration, body mass index, or disease activity of RA patients. Adiponectin is decreased in synovial fluid compared to serum indicating that peripheral fat stores are major producers of adiponectin into the blood stream. However, increased synovial fluid adiponectin in RA patients may counterpart the local inflammatory process.

We studied the effect of peroxisome proliferator-activated receptor-alpha (PPAR-alpha) activation on serum concentrations and tissue expression of resistin, adiponectin, and adiponectin receptor-1 and -2 (AdipoR1 and AdipoR2) mRNA in normal mice and mice with insulin resistance induced by lipogenic, simple-carbohydrate diet (LD). Sixteen weeks of LD feeding induced obesity with liver steatosis and increased insulin levels but did not significantly affect circulating adiponectin or resistin. Treatment with PPAR-alpha agonist fenofibrate decreased body weight and fat pad weight and ameliorated liver steatosis in LD-fed mice with concomitant reduction in blood glucose, free fatty acid, triglyceride, serum insulin levels, and homeostasis model assessment index values. Euglycemic-hyperinsulinemic clamp demonstrated the development of whole-body and liver insulin resistance in LD-fed mice, which were both normalized by fenofibrate. Fenofibrate treatment markedly increased circulating resistin levels on both diets and adiponectin levels in chow-fed mice only. Fat adiponectin mRNA expression was not affected by fenofibrate treatment. Resistin mRNA expression increased in subcutaneous but not gonadal fat after fenofibrate treatment. In addition to fat, a significant amount of adiponectin mRNA was also expressed in the muscle. This expression markedly increased after fenofibrate treatment in chow- but not in LD-fed mice. Adipose tissue expression of AdipoR1 mRNA was significantly reduced in LD-fed mice and increased after fenofibrate treatment. In conclusion, PPAR-alpha activation ameliorated the development of insulin resistance in LD-fed mice despite a major increase in serum resistin levels. This effect could be partially explained by increased AdipoR1 expression in adipose tissue after fenofibrate treatment.

Organ allograft recipients are at higher risk for malignancies development. This risk is known to be different in different types of tumours. Skin cancers and lymphoproliferative disorders have been described to be ones the most frequent (comprising 15-25% of all malignancies). Here, we present the case of expansive formation localized near the renal allograft in patient, whose native kidneys failed as a consequence of long-term cyclosporine A therapy after orthotopic heart transplantation. The maintenance immunosuppression consisted of combination of cyclosporine A, mycophenolate mofetil and steroids. The expansion offside of transplanted kidney was detected by routine ultrasound examination. After indifferent neurological symptoms, sepsis, and then multiorgan failure occured. Shortly after acute surgery patient died. Autopsy and histopathology showed lymphoproliferative disorder--mo- nomorphic type of posttransplant lymphoproliferative disorder (PTLD). Occurence of PTLD in organ transplantation is discussed.

Autosomal recessive rat hypodactylous mutation Hd leads in homozygous condition to reductive changes of the digital arch of all feet. There is a variable preaxial reduction of the number of fingers in both sexes. Moreover, homozygous males are sterile. Testes of homozygous Hd/Hd and +/Hd adult rats were examined in the light and electron microscopes. Spatial organization of stages of the spermatogenetic cycle was not confirmed in Hd/Hd testes comparing with +/Hd males. Significant decrease in the number of germ cells in seminiferous tubules of Hd/Hd testes was accompanied with loosening and vacuolization of the seminiferous epithelium. The assignment of the Hd locus to RNO10 excluded the suspected homology between rat and mouse Hd mutations. More precise mapping using microsatellite markers revealed close linkage of the Hd locus with the D1OMit8 marker defining Syb2 gene coding for synaptobrevin 2. A chromosomal segment of RNO10 carrying Hd and Syb genes is being incrossed onto BN and SHR inbred strains in order to examine the modifying influences of different genetic backgrounds.
