Inhibitory smads and tgf-Beta signaling in glomerular cells

Smad6 and Smad7 are inhibitory SMADs with putative functional roles at the intersection of major intracellular signaling networks, including TGF-beta, receptor tyrosine kinase (RTK), JAK/STAT, and NF-kappaB pathways. This study reports differential functional roles and regulation of Smad6 and Smad7 in TGF-beta signaling in renal cells, in murine models of renal disease and in human glomerular diseases. Smad7 is upregulated in podocytes in all examined glomerular diseases (focal segmental glomerulosclerosis [FSGS], minimal-change disease [MCD], membranous nephropathy [MNP], lupus nephritis [LN], and diabetic nephropathy [DN]) with a statistically significant upregulation in "classical" podocyte-diseases such as FSGS and MCD. TGF-beta induces Smad7 synthesis in cultured podocytes and Smad6 synthesis in cultured mesangial cells. Although Smad7 expression inhibited both Smad2- and Smad3-mediated TGF-beta signaling in podocytes, it inhibited only Smad3 but not Smad2 signaling in mesangial cells. In contrast, Smad6 had no effect on TGF-beta/Smad signaling in podocytes and enhanced Smad3 signaling in mesangial cells. These data suggest that Smad7 is activated in injured podocytes in vitro and in human glomerular disease and participates in negative control of TGF-beta/Smad signaling in addition to its pro-apoptotic activity, whereas Smad6 has no role in TGF-beta response and injury in podocytes. In contrast, Smad6 is upregulated in the mesangium in human glomerular diseases and may be involved in functions independent of TGF-beta/Smad signaling. These data indicate an important role for Smad6 and Smad7 in glomerular cells in vivo that could be important for the cell homeostasis in physiologic and pathologic conditions.

Reduction of hepatic and adipose tissue glucocorticoid receptor expression with antisense oligonucleotides improves hyperglycemia and hyperlipidemia in diabetic rodents without causing systemic glucocorticoid antagonism

Glucocorticoids (GCs) increase hepatic gluconeogenesis and play an important role in the regulation of hepatic glucose output. Whereas systemic GC inhibition can alleviate hyperglycemia in rodents and humans, it results in adrenal insufficiency and stimulation of the hypothalamic-pituitary-adrenal axis. In the present study, we used optimized antisense oligonucleotides (ASOs) to cause selective reduction of the glucocorticoid receptor (GCCR) in liver and white adipose tissue (WAT) and evaluated the resultant changes in glucose and lipid metabolism in several rodent models of diabetes. Treatment of ob/ob mice with GCCR ASOs for 4 weeks resulted in approximately 75 and approximately 40% reduction in GCCR mRNA expression in liver and WAT, respectively. This was accompanied by approximately 65% decrease in fed and approximately 30% decrease in fasted glucose levels, a 60% decrease in plasma insulin concentration, and approximately 20 and 35% decrease in plasma resistin and tumor necrosis factor-alpha levels, respectively. Furthermore, GCCR ASO reduced hepatic glucose production and inhibited hepatic gluconeogenesis in liver slices from basal and dexamethasone-treated animals. In db/db mice, a similar reduction in GCCR expression caused approximately 40% decrease in fed and fasted glucose levels and approximately 50% reduction in plasma triglycerides. In ZDF and high-fat diet-fed streptozotocin-treated (HFD-STZ) rats, GCCR ASO treatment caused approximately 60% reduction in GCCR expression in the liver and WAT, which was accompanied by a 40-70% decrease in fasted glucose levels and a robust reduction in plasma triglyceride, cholesterol, and free fatty acids. No change in circulating corticosterone levels was seen in any model after GCCR ASO treatment. To further demonstrate that GCCR ASO does not cause systemic GC antagonism, normal Sprague-Dawley rats were challenged with dexamethasone after treating with GCCR ASO. Dexamethasone increased the expression of GC-responsive genes such as PEPCK in the liver and decreased circulating lymphocytes. GCCR ASO treatment completely inhibited the increase in dexamethasone-induced PEPCK expression in the liver without causing any change in the dexamethasone-induced lymphopenia. These studies demonstrate that tissue-selective GCCR antagonism with ASOs may be a viable therapeutic strategy for the treatment of the metabolic syndrome.     

Twenty‐Four‐Hour Patterns of Hormones and Metabolites in Week 9 and 19 of Lactation in High‐Yielding Dairy Cows fed Triglycerides and Free Fatty Acids

Effects of feeding crystalline triglycerides (TGA), free fatty acids (FFA), and a starch‐rich ration (STA) on metabolite and hormone concentrations in blood plasma were studied in high‐yielding dairy cows over a 24‐h period in week 9 and 19 of lactating. Energy‐corrected milk production in the three groups was similar, but was lower in week 19 than in week 9. Energy and protein intakes were greater in week 9 than in week 19, but energy and protein balances in the three groups and in weeks 9 and 19 were similar. Plasma glucose and triglyceride concentrations were lower in week 9 than in week 19. In cows fed FFA, glucose concentrations were highest in week 9. Plasma triglyceride, phospholipid and cholesterol concentrations were highest, whereas β‐hydroxybutyrate concentrations were lowest in FFA‐fed cows in weeks 9 and 19. Concentrations of insulin‐like growth factor‐I in week 19 were lower in cows fed TGA and FFA than in those fed the starch‐rich ration. Post‐prandial responses were usually greater following morning than afternoon meals. Fructosamine, albumin, urea, growth hormone, thyroxine, and 3,5,3′‐triiodothyronine concentrations were similar in weeks 9 and 19 and were not influenced by dietary treatment or feeding times. In conclusion, there were distinct metabolic and endocrine effects of feeding TGA and FFA compared with STA and the concentrations as well as the 24‐h changes of various metabolic and endocrine traits in weeks 9 and 19 of lactation were also different.

血小板中cAMP与cGMP及血清LDL-ch对犬下腔静脉移植物内膜增生的影响

为探讨静脉系移植物通畅率的影响因素，对自体静脉碎片种植Ｄａｃｒｏｎ后植入下腔静脉（ＩＶＣ）的１３只犬及全血预凝Ｄａｃｒｏｎ后植入ＩＶＣ作对照的８只犬血清脂蛋白胆固醇、血小板环－磷酸腺苷（ｃＡＭＰ）、环－磷酸鸟苷（ｃＧＭＰ）及移植物内膜厚度进行了测定。结果：种植组通畅率（６１．５％）高于对照组（２５．０％），Ｄａｃｒｏｎ腔面术后２周完全内皮化；对照阻塞组与种植阻塞组血小板ｃＡＭＰ低于对照通畅组与种植通畅组，血清低密度脂蛋白胆固醇（ＬＤＬ－ｃｈ）高于对照通畅组与种植通畅组，前二组内膜厚度大于后二组。结果提示：内皮层不完整所致腔面前列环素及血小板ｃＡＭＰ减少，可能是静脉系移植物内膜增生的主要原因，高ＬＤＬ－ｃｈ血症可能对其有促进作用；人工血管内皮化，抗血小板与降血脂处理对预防内膜增生及提高通畅率可能有帮助。     

Regulation of kallikrein and renin release by the isolated perfused rat kidney

Rat kidneys perfused in vitro released kallikrein in urine, and renin and kallikrein in the perfusate. The kallikrein was characterized by its kininogenase activity and released bradykinin from bovine and dog substrates. Inactive trypsin activatable kallikrein was present in both perfusate and urine. Kallikrein secretion in urine was influenced by changes in perfusion pressure (PP). Raising the PP strikingly increased urinary kallikrein and lowering PP reduced it. Urinary water and electrolyte output were augmented to the same extent by furosemide and mannitol administration as by raising the PP, but neither drug affected kallikrein. Isoproterenol stimulated the release of renin but not kallikrein. Stopping the oxygen supply to the perfusate suppressed kallikrein secretion in urine and renin release in the perfusate. The kidneys released ten times less kallikrein in the perfusate than in urine, and perfusate kallikrein was not influenced by changes in PP. It is concluded that in this model, changes in PP and/or renal blood flow and/or oxygen supply regulate kallikrein secretion in urine, but that this secretion is unaffected by changes in urinary output. We also conclude that kallikrein release in urine and renin release in perfusate are regulated simultaneously by renal hemodynamic changes but are not affected concomitant by beta-adrenergic stimulation or changes in distal urine composition.     

Liver transplantation and portal thrombosis

One hundred and thirty-eight transplants were performed between April 1986 and June 1990 in 116 patients of whom 9 (7.75%) were affected by liver cirrhosis complicated by portal vein thrombosis. Occlusion of the vascular lumen was total in 3 cases, semitotal in 1 case and the percentage of obstruction ranged between 25% and 75% in the remaining patients. Venous dissection and thrombectomy were performed in 6 cases and simple thrombectomy in 3 cases in order to obtain a satisfactory blood flow. Anastomosis was effected using the spleno-mesenteric confluence in 2 cases and the portal vein itself in other patients. Recurrent thrombosis occurred in the first 4 patients in the series, but it was only fatal in 2 cases. The paper analyses the data obtained from the study and in conclusion confirms the use of transplant in cirrhotic patients with portal vein thrombosis.     

Influence of patient's age and fracture morphology on the final result of conservative treatment]

Three hundred and thirty-three cases of the distal radius fractures have been retrospectively analyzed. The patients were divided into 4 age groups (15-29, 30-49, 50-69 and above 70 years of age) and into 8 groups according to Frykman's classification of fracture morphology. Excellent and good results in the first and second age group were found in 84.3% (patients evaluation), in 85.3% (clinical evaluation according to Gartland-Werley criteria) and in 87.2% (radiologic Sarmiento scale). The scores in age groups III and IV were 69.7%, 67.1% and 52.4% respectively. Extraarticular fractures (Frykman I and II) were found in 69.7% in age groups II and I and in 37.3% in group III and IV. Excellent and good results in the extraarticular fractures group were found in 88% subjectively, 84.2% clinically and in 85.1% radiologically whilst in the intraarticular fractures group in 57.6%, 59.3% and 37.4% respectively. Clinical and radiologic results worsen as the fracture morphology gets more complicated and this occurs with increasing age of the patient.

Dialysis-Induced Changes in Muscle Strength

Little is known about the acute effects of hemodialysis on muscle strength. Rapid changes in hemodynamic and biochemical parameters are known to occur during dialysis and may alter muscle performance. Ten patients maintained on chronic hemodialysis had measurements of quadriceps muscle and handgrip strength performed before and after dialysis In seven of these patients maximum static inspiratory and expiratory pressures (PI max and PE max respectively) were similarly determined. Quadriceps muscle strength improved in 6 patients, decreased in 3 and remained unchanged in 1. Handgrip strength increased in 5 patients, decreased in 3, and remained unchanged in 1. PI max decreased in 6 patients and increased in 1, and PE max decreased in 4 patients and increased in 3. No significant correlation was found between the changes in strength of the tested muscle groups and the serum concentrations of sodium, potassium, calcium, phosphous, urea nitrogen, and creatinine, changes in blood pressure or fluid balance. The dialysis-induced changes in biochemical parameters may exert opposing effects on neuromuscular performance. This may explain the diversity of the results obtained in this study.

Trends in the prevalence of asthma in Scottish and English primary school children 1982-92.

BACKGROUND--Some doubts exist as to whether the increase in the prevalence of asthma is real or an artefact. The 10 year trend of asthma up to 1993 in England and Scotland was therefore assessed. METHODS--Information on asthma and bronchitis attacks, occasional wheeze, and persistent wheeze in the last 12 months, was obtained using a self administered questionnaire completed by the parents. Exactly the same questions were asked in 14 study areas in Scotland and 22 study areas in England in 1982 or 1983 and in 1992 or 1993 in 5-11 year old children. RESULTS--The numbers of children with data for all respiratory illness were 5556 (85.2%) and 5801 (87.1%) in England and 3748 (90.4%) and 3738 (90.4%) in Scotland in 1982 and 1992, respectively. There was a significant increase in asthma attacks (approximately three times more in 1992 than in 1982) and occasional wheeze (30-60% more in 1992 than in 1982) in both sexes in England and Scotland. Persistent wheeze also increased in both countries, but the increase was significant only in England (30-40% more in 1992 than in 1982). CONCLUSIONS--The study coincides with others that suggest that the increased prevalence of asthma may be due, in part, to changes in diagnostic behaviour. However, the continuing increase of persistent wheeze in the total sample suggests that part of the increase is real. There was no difference in the increase of persistent wheeze between Scotland and England, but the trend was only significant in England.     

人创面愈合过程中同源异形框基因的表达及意义

目的 探讨人胎儿及成人皮肤创面愈合过程中，几种同源异形框基因的表达及在胎儿无瘢痕愈合中的作用。方法 采用原位杂交方法，对正常成人和胎儿皮肤及创面愈合过程中PRX—2、H0XBl3、H0X2．2和H0X2．3的表达进行观察。结果 (1)在正常胎儿和成人皮肤中可见PRX—2阳性表达，以前阳性程度为强。分布部位有所不同，在正常胎儿皮肤中，阳性表达主要见于真皮乳头层毛干部周围细胞，表皮中也可见阳性表达；而在正常成人皮肤中，表皮基底层细胞呈弱阳性表达，真皮组织中未见阳性表达。胎儿皮肤创伤后，接近切口的组织中阳性表达明显增强，而成人皮肤创伤后，阳性表达未见明显变化，仍局限于表皮基底层细胞；(2)在正常胎儿及成人皮肤均可见H0XBl3阳性表达，真皮部分主要集中在毛囊细胞，表皮部分主要集中在基底层细胞，创伤后其表达明显减弱，尤其是胎儿皮肤；(3)在正常胎儿皮肤中H0X2．2和H0X2．3阳性表达主要见于表皮全层，表皮基底层阳性表达比较强，真皮中可见弱阳性表达，创伤后近切口的组织中，表达增强。在正常成人皮肤及其创面，未见到阳性表达。结论 同源异形框基因作为与发育生物学密切相关的基因，在人胎儿及成人皮肤创面愈合过程中的表达有所不同，这可能是二创面愈合差异的根本原因。     

Declining Coronary Heart Disease Mortality in Iceland: Contribution by Incidence,Recurrence and Case Fatality Rate

Objective : To analyse to what extent the recent decline in coronary heart disease mortality in Iceland is due to changes in incidence, recurrence and case fatality rates. Design : A countrywide registration of myocardial infarction (MI) in people aged 25-74 was performed in Iceland during 1981-1999 according to the MONICA protocol. Possible cases were found by review of all hospital discharge records, autopsy records and death certificates. Results : MI death rate declined by 63% in males and 51% in females, most in the youngest age groups in men (86%) and least in the oldest (49%). In women there was not a significant difference in age groups. Overall the age-adjusted reduction in MI death rate was 55.4% in both sexes combined; of this 23.1% was due to incidence reduction, 22.8% to recurrence reduction and 11.6% to case fatality reduction. In the youngest age groups the decline in incidence contributed most to the decline in MI death rate (62% in men and 71% in women), but thereafter the decline in case fatality in men. In the older age groups decline in recurrence rate has greater weight. Conclusion : The recent decline in MI mortality under the age of 75 years in Iceland is due to reduction in incidence and recurrence rate by about 40% each and to reduction in case fatality by 20%.     

Association of EMMPRIN and fascin expression in renal cell carcinoma: correlation with clinicopathological parameters

EMMPRIN and fascin are important factors in tumor invasion and progression. We tested the hypothesis that expression of EMMPRIN and fascin correlate with clinicopathological parameters of renal cell carcinoma (RCC). Immunohistochemical analysis of EMMPRIN and fascin were performed in tissue microarrays of 100 surgical specimens, including 35 clear-cell RCC (CRCC), 21 clear-cell RCC with granular differentiation (GRCC), 12 chromophobe RCC (ChRCC), 8 papillary RCC (PRCC), 9 carcinoma of the collecting duct of Bellini (CDC), 10 clear-cell RCC with sarcomatoid differentiation (SRCC), and 6 metastatic RCC. Average immunoscores of EMMPRIN were 100.8 in CRCC, 195.2 in GRCC, 298.4 in ChRCC, 219.2 in PRCC, 186.1 in CDC, 226.9 in SRCC, and 151.7 in metastatic RCC. Among all included cases, average EMMPRIN immunoscores were 84.6 in grade I, 130.4 in grade II, 184.3 in grade III, and 223.5 in grade IV. Additionally, average immunostaining scores of fascin were 53.6 in CRCC, 289.3 in GRCC, 193.3 in ChRCC, 151.8 in PRCC, 181.3 in CDC, 275.4 in SRCC, and 131.7 in metastatic RCC. Average fascin immunoscores were 59.3 in grade I, 91.6 in grade II, 130.2 in grade III, and 194.7 in grade IV. Higher EMMPRIN and fascin immunoscores also correlated significantly with TNM stages and survival rates in RCC. Significant correlation was found between EMMPRIN and fascin expression. In conclusion, higher expression of EMMPRIN and fascin correlate significantly with histological grades, clinical stages, and survival rates of RCC
