| 1 | Sitagliptin in patients with non-alcoholic steatohepatitis: A randomized, placebo-controlled trial显示文摘AIM To evaluate the effect of sitagliptin vs placebo on histologic and non-histologic parameters of nonalcoholic steatohepatitis(NASH).METHODS Twelve patients with biopsy-proven NASH were randomized to sitagliptin(100 mg daily)(n=6)or placebo(n=6)for 24 wk.The primary outcome was improvement in liver fibrosis after 24 wk.Secondary outcomes included evaluation of changes in NAFLD activity score(NAS),individual components of NAS(hepatocyte ballooning,lobular inflammation,and steatosis),glycemic control and insulin resistance[including measurements of glycated hemoglobin(Hb A1C)and adipocytokines],lipid profile including free fatty acids,adipose distribution measured using magnetic resonance imaging(MRI),and thrombosis markers(platelet aggregation and plasminogen activator inhibitor 1 levels).We also sought to determine the correlation between changes in hepatic fat fraction(%)[as measured using the Iterative Decomposition of water and fat with Echo Asymmetry and Least-squares estimation(IDEAL)MRI technique]and changes in hepatic steatosis on liver biopsy.RESULTS Sitagliptin was not significantly better than placebo at reducing liver fibrosis score as measured on liver biopsy(mean difference between sitagliptin and placebo arms,0.40,P=0.82).There were no significant improvements evident with the use of sitagliptin vs placebo for the secondary histologic outcomes of NAS total score as well as for the individual components of NAS.Compared to baseline,those patients who received sitagliptin demonstrated improved Hb A1C(6.7%±0.4%vs 7.9%±1.0%,P=0.02),and trended towards improved adiponectin levels(4.7±3.5μg/m L vs 3.9±2.7μg/m L,P=0.06)and triglyceride levels(1.26±0.43 mmol/L vs 2.80±1.64 mmol/L,P=0.08).However,when compared with placebo,sitagliptin did not cause a statistically significant improvement in Hb A1C(mean difference,-0.7%,P=0.19)nor triglyceride levels(mean difference-1.10mmol/L,P=0.19)but did trend towards improved adiponectin levels only(mean difference,0.60μg/m L,P=0.095).No significant changes in anthropometrics,liver enzymes,other adipocytokines,lipid profile,thrombosis parameters,or adipose distribution were demonstrated.The MRI IDEAL procedure correlated well with steatosis scores obtained on liver biopsy in both groups at baseline and post-treatment,and the Spearman correlation coefficients ranged from r=0.819(baseline)to r=0.878(post-treatment),P=0.002.CONCLUSION Sitagliptin does not improve fibrosis score or NAS after 24 wk of therapy.The MRI IDEAL technique may be useful for non-invasive measurement of hepatic steatosis. | Tisha R Joy Charles A McKenzie Rommel G Tirona Kelly Summers Shannon Seney Subrata Chakrabarti Neel Malhotra Melanie D Beaton | 2017 | World Journal of Gastroenterology2017，23，1： | 18 |
| 2 | The wonders of BMP9:From mesenchymal stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism to regenerative medicine显示文摘Although bone morphogenetic proteins(BMPs)initially showed effective induction of ectopic bone growth in muscle,it has since been determined that these proteins,as members of the TGF-b superfamily,play a diverse and critical array of biological roles.These roles include regulating skeletal and bone formation,angiogenesis,and development and homeostasis of multiple organ systems.Disruptions of the members of the TGF-b/BMP superfamily result in severe skeletal and extra-skeletal irregularities,suggesting high therapeutic potential from understanding this family of BMP proteins.Although it was once one of the least characterized BMPs,BMP9 has revealed itself to have the highest osteogenic potential across numerous experiments both in vitro and in vivo,with recent studies suggesting that the exceptional potency of BMP9 may result from unique signaling pathways that differentiate it from other BMPs.The effectiveness of BMP9 in inducing bone formation was recently revealed in promising experiments that demonstrated efficacy in the repair of critical sized cranial defects as well as compatibility with bone-inducing bio-implants,revealing the great translational promise of BMP9.Furthermore,emerging evidence indicates that,besides its osteogenic activity,BMP9 exerts a broad range of biological functions,including stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism.This review aims to summarize our current understanding of BMP9 across biology and the body. | Sami Mostafa Mikhail Pakvasa Elam Coalson Allen Zhu Alex Alverdy Hector Castillo Jiaming Fan Alex Li Yixiao Feng Di Wu Elliott Bishop Scott Du Mia Spezia Alissa Li Ofir Hagag Alison Deng Winny Liu Mingyang Li Sherwin S·Ho Aravind Athiviraham Michael J·Lee Jennifer Moriatis Wolf Guillermo A·Ameer Hue H·Luu Rex C·Haydon Jason Strelzow Kelly Hynes Tong-Chuan He Russell R·Reid | 2019 | Genes & Diseases2019，6，3： | 15 |

| 4 | Th1 cytokines promote T-cell binding to antigen-presenting cells via enhanced hyaluronan production and accumulation at the immune synapse显示文摘Hyaluronan(HA)production by dendritic cells(DCs)is known to promote antigen presentation and to augment T-cell activation and proliferation.We hypothesized that pericellular HA can function as intercellular‘glue’directly mediating T cell–DC binding.Using primary human cells,we observed HA-dependent binding between T cells and DCs,which was abrogated upon pre-treatment of the DCs with 4-methylumbelliferone(4-MU),an agent which blocks HA synthesis.Furthermore,T cells regulate HA production by DCs via T cell-derived cytokines in a T helper(Th)subset-specific manner,as demonstrated by the observation that cell-culture supernatants from Th1 but not Th2 clones promote HA production.Similar effects were seen upon the addition of exogenous Th1 cytokines,IL-2,interferon c(IFN-c)and tumor necrosis factor a(TNF-a).The critical factors which determined the extent of DC–T cell binding in this system were the nature of the pre-treatment the DCs received and their capacity to synthesize HA,as T-cell clones which were pre-treated with monensin,added to block cytokine secretion,bound equivalently irrespective of their Th subset.These data support the existence of a feedforward loop wherein T-cell cytokines influence DC production of HA,which in turn affects the extent of DC–T cell binding.We also document the presence of focal deposits of HA at the immune synapse between T-cells and APC and on dendritic processes thought to be important in antigen presentation.These data point to a pivotal role for HA in DC–T cell interactions at the IS. | Paul L Bollyky Stephen P Evanko Rebecca P Wu Susan Potter-Perigo S Alice Long Brian Kinsella Helena Reijonen Kelly Guebtner Brandon Teng Christina K Chan Kathy R Braun John A Gebe Gerald T Nepom Thomas N Wight | 2010 | Cellular & Molecular Immunology2010，7，3： | 3 |
