MiR-340 mediates the involvement of high mobility group box 1 in the pathogenesis of liver fibrosis / 中华肝脏病杂志

Objective: To explore the pathogenic mechanism of the miR-340/high mobility group box 1 (HMGB1) axis in the formation of liver fibrosis. Methods: A rat liver fibrosis model was established by injecting CCl(4) intraperitoneally. miRNAs targeting and validating HMGB1 were selected with gene microarrays after screening the differentially expressed miRNAs in rats with normal and hepatic fibrosis. The effect of miRNA expressional changes on HMGB1 levels was detected by qPCR. Dual luciferase gene reporter assays (LUC) was used to verify the targeting relationship between miR-340 and HMGB1. The proliferative activity of the hepatic stellate cell line HSC-T6 was detected by thiazolyl blue tetrazolium bromide (MTT) assay after co-transfection of miRNA mimics and HMGB1 overexpression vector, and the expression of extracellular matrix (ECM) proteins type I collagen and α-smooth muscle actin (SMA) was detected by western blot. Statistical analysis was performed by analysis of variance and the LSD-t test. Results: Hematoxylin-eosin and Masson staining results showed that the rat model of liver fibrosis was successfully established. Gene microarray analysis and bioinformatics prediction had detected eight miRNAs possibly targeting HMGB1, and animal model validation had detected miR-340. qPCR detection results showed that miR-340 had inhibited the expression of HMGB1, and a luciferase complementation assay suggested that miR-340 had targeted HMGB1. Functional experiments results showed that HMGB1 overexpression had enhanced cell proliferation activity and the expression of type I collagen and α-SMA, while miR-340 mimics had not only inhibited cell proliferation activity and the expression of HMGB1, type I collagen, and α-SMA, but also partially reversed the promoting effect of HMGB1 on cell proliferation and ECM synthesis. Conclusion: miR-340 targets HMGB1 to inhibit the proliferation and ECM deposition in hepatic stellate cells and plays a protective role during the process of liver fibrosis.

Recognition of a tandem lesion by DNA bacterial formamidopyrimidine glycosylases explored combining molecular dynamics and machine learning.

The combination of several closely spaced DNA lesions, which can be induced by a single radical hit, constitutes a hallmark in the DNA damage landscape and radiation chemistry. The occurrence of such a tandem base lesion gives rise to a strong coupling with the double helix degrees of freedom and induces important structural deformations, in contrast to DNA strands containing a single oxidized nucleobase. Although such complex lesions are known to be refractory to repair by DNA glycosylases, there is still a lack of structural evidence to rationalize these phenomena. In this contribution, we explore, by numerical modeling and molecular simulations, the behavior of the bacterial glycosylase responsible for base excision repair (MutM), specialized in excising oxidatively-damaged defects such as 7,8-dihydro-8-oxoguanine (8-oxoG). The difference in lesion recognition between a simple damage and a tandem lesion featuring an additional abasic site is assessed at atomistic resolution owing to microsecond molecular dynamics simulations and machine learning postprocessing, allowing to extensively pinpoint crucial differences in the interaction patterns of the damaged bases. Our results reveal substantial changes in the interaction network surrounding the 8-oxoG upon addition of an adjacent abasic site, leading to the perturbation of the intercalation triad which is crucial for lesion recognition and processing. The recognition process might also be impacted by a more constrained MutM-DNA binding upon tandem damage, as shown by the machine learning post-processing. This work advocates for the use of such high throughput numerical simulations for exploring the complex combinatorial chemistry of tandem DNA lesions repair and more generally local multiple damaged sites of the utmost significance in radiation chemistry.

Hexavalent lactoside labeled with [18F]AlF for PET imaging of asialoglycoprotein receptor.

Several methods have been developed to label compounds with 18F. However, in general these are laborious and require a multistep synthesis. A method based on the chelation of 18F-aluminum fluoride ([18F]AlF) by 1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA) was developed recently. The present work was aimed to radiolabel hexavalent lactoside (NOTA-HL) by [18F]AlF method for PET imaging of asialoglycoprotein receptor (ASGPR). METHODS: hexavalent lactoside was conjugated with the NOTA chelate and labeled with 18F in a one-pot method. The labeling procedure was investigated with different amounts of NOTA-HL and aluminum concentration. Radiochemical yield and radiochemical purity were determined by radio-TLC and radio-HPLC respectively. In vitro stability study of [18F]AlF-HL were carried out. PET/CT imaging of normal mice injected with [18F]AlF-NOTA-HL was performed. RESULTS: The Radiochemical yield of [18F]AlF-NOTA-HL was higher with more precursor and optimal Al+ concentration. The radiochemical purity of labeled product was >95% after purified by Sep-Pak cartridge to remove unbound [18F]AlF. The radiolabeling, including purification, was performed in 30 min [18F]AlF-NOTA-HL exhibited good in vitro stability. PET studies in normal mice revealed high specific accumulation of activity in the liver. CONCLUSION: NOTA-HL could be labeled rapidly and efficiently with aqueous 18F using AlF method. [18F]AlF-NOTA-HL would provide another efficient approach for PET imaging of ASGPR.

Effect of the Ligand Binding Strength on the Morphology of Functionalized Gold Nanoparticles.

Functionalized gold nanoparticles are investigated by density functional theory calculations in the context of cancer radiotherapy. Several typical experimental shapes, including nanostars, nanospheres, and nanorods, are modeled by optimizing Au clusters covered by organic monolayers composed of hydrated short-chain polyethylene glycol (PEG) ligands. The PEGylation stabilizes significantly the stellation of decahedral Au54 by deforming significantly its geometry at the spikes. The higher stability of the PEG molecules adsorbed on this stellated nanocluster with respect to the more spherical icosahedral Au55 and truncated octahedral Au79 leads to a larger energy cost to desorb them and thus a weaker propensity for the starred nanoparticle to exchange ligands with the cell membrane, in agreement with experiments. These results open interesting possibilities for advancing our understanding of the cellular uptake of gold nanoparticles.

Small molecule proteomics quantifies differences between normal and fibrotic pulmonary extracellular matrices / 中华医学杂志(英文版)

BACKGROUND@#Pulmonary fibrosis is a respiratory disease caused by the proliferation of fibroblasts and accumulation of the extracellular matrix (ECM). It is known that the lung ECM is mainly composed of a three-dimensional fiber mesh filled with various high-molecular-weight proteins. However, the small-molecular-weight proteins in the lung ECM and their differences between normal and fibrotic lung ECM are largely unknown.@*METHODS@#Healthy adult male Sprague-Dawley rats (Rattus norvegicus) weighing about 150 to 200 g were randomly divided into three groups using random number table: A, B, and C and each group contained five rats. The rats in Group A were administered a single intragastric (i.g.) dose of 500 μL of saline as control, and those in Groups B and C were administered a single i.g. dose of paraquat (PQ) dissolved in 500 μL of saline (20 mg/kg). After 2 weeks, the lungs of rats in Group B were harvested for histological observation, preparation of de-cellularized lung scaffolds, and proteomic analysis for small-molecular-weight proteins, and similar procedures were performed on Group C and A after 4 weeks. The differentially expressed small-molecular-weight proteins (DESMPs) between different groups and the subcellular locations were analyzed.@*RESULTS@#Of the 1626 small-molecular-weight proteins identified, 1047 were quantifiable. There were 97 up-regulated and 45 down-regulated proteins in B vs. A, 274 up-regulated and 31 down-regulated proteins in C vs. A, and 237 up-regulated and 28 down-regulated proteins identified in C vs. B. Both the up-regulated and down-regulated proteins in the three comparisons were mainly distributed in single-organism processes and cellular processes within biological process, cell and organelle within cellular component, and binding within molecular function. Further, more up-regulated than down-regulated proteins were identified in most sub-cellular locations. The interactions of DESMPs identified in extracellular location in all comparisons showed that serum albumin (Alb) harbored the highest degree of node (25), followed by prolyl 4-hydroxylase beta polypeptide (12), integrin β1 (10), apolipoprotein A1 (9), and fibrinogen gamma chain (9).@*CONCLUSIONS@#Numerous PQ-induced DESMPs were identified in de-cellularized lungs of rats by high throughput proteomics analysis. The DESMPs between the control and treatment groups showed diversity in molecular functions, biological processes, and pathways. In addition, the interactions of extracellular DESMPs suggested that the extracellular proteins Alb, Itgb1, Apoa1, P4hb, and Fgg in ECM could be potentially used as biomarker candidates for pulmonary fibrosis. These results provided useful information and new insights regarding pulmonary fibrosis.

Probing interaction of a trilysine peptide with DNA underlying formation of guanine-lysine cross-links: insights from molecular dynamics.

DNA-protein cross-links constitute bulky DNA lesions that interfere with the cellular machinery. Amongst these stable covalently tethered adducts, the efficient nucleophilic addition of the free amino group of lysines onto the guanine radical cation has been evidenced. In vitro addition of a trilysine peptide onto a guanine radical cation generated in a TGT oligonucleotide is so efficient that competitive addition of a water molecule, giving rise to 8-oxo-7,8-dihydroguanine, is not observed. This suggests a spatial proximity between guanine and lysine for the stabilization of the prereactive complex. We report all-atom microsecond scale molecular dynamics simulations that probe the structure and interactions of the trilysine peptide (KKK) with two oligonucleotides. Our simulations reveal a strong, electrostatically driven yet dynamic interaction, spanning several association modes. Furthermore, the presence of neighbouring cytosines has been identified as a factor favoring KKK binding. Relying on ab initio molecular dynamics on a model system constituted of guanine and methylammonium, we also corroborate a mechanistic pathway involving fast deprotonation of the guanine radical cation followed by hydrogen transfer from ammonium leaving as a result a nitrogen reactive species that can subsequently cross-link with guanine. Our study sheds new light on a ubiquitous mechanism for DNA-protein cross-links also stressing out possible sequence dependences.

A Water Solvation Shell Can Transform Gold Metastable Nanoparticles in the Fluxional Regime.

Solvated gold nanoparticles have been modeled in the fluxional regime by density functional theory including dispersion forces for an extensive set of conventional morphologies. The study of isolated adsorption of one water molecule shows that the most stable adsorption forms are similar (corners and edges) regardless of the nanoparticle shape and size, although the adsorption strength differs significantly (0.15 eV). When a complete and explicit water solvation shell interacts with gold nanoclusters, metastable in vacuum and presenting a predominance of (100) square facets (ino-decahedra Au55 and Au147), these nanoparticles are found unstable and transform into the closest morphologies exhibiting mainly (111) triangular facets and symmetries. The corresponding adsorption strength per water molecule becomes independent of shape and size and is enhanced by the formation of two hydrogen bonds on average. For applications in radiotherapy, this study suggests that the shapes of small gold nanoparticles should be homogenized by interacting with the biological environment.

68Ga-labelled NOTA-RGD-GE11 peptide for dual integrin and EGFR-targeted tumour imaging.

INTRODUCTION: Multiple peptide receptors are co-expressed in many types of cancers. Arg-Gly-Asp (RGD) and GE11 peptides specifically target integrin αVß3 and EGFR, respectively. Recently, we designed and synthesized a heterodimer peptide NOTA-c(RGDyK)-GE11 (NOTA-RGD-GE11). The aim of this study was to investigate the characteristics of NOTA-RGD-GE11 for dual receptor imaging. METHODS: NOTA-RGD-GE11 heterodimer was labelled with 68Ga. The dual receptor binding affinity was investigated by antibody competition binding assay. The in vitro and in vivo characteristics of [68Ga]Ga-NOTA-RGD-GE11 were investigated and compared with that of monomeric peptides [68Ga]Ga-NOTA-RGD and [68Ga]Ga-NOTA-GE11. RESULTS: NOTA-RGD-GE11 had binding affinities with both integrin αVß3 and EGFR. The dual receptor targeting property of [68Ga]Ga-NOTA-RGD-GE11 was validated by blocking studies in a NCI-H292 tumour model. [68Ga]Ga-NOTA-RGD-GE11 showed higher tumour uptake than [68Ga]Ga-NOTA-RGD and [68Ga]Ga-NOTA-GE11 in biodistribution and PET/CT imaging studies. CONCLUSION: The dual receptor targeting and enhanced tumour uptake of [68Ga]Ga-NOTA-RGD-GE11 warrant its further investigation for dual integrin αVß3 and EGFR-targeted tumour imaging.

OBJECTIVE: To explore the value of water swallow test(WST)and simple two-step swallowing provocation test(SSPT)in the diagnosis of aspiration in patients with acute exacerbation of chronic obstructive pulmonary disease. METHODS:87 hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease were recruited from the First Affiliated Hospital of Guangzhou Medical University during the period between December 2014 to December 2015. RESULTS: The number of patients of grade1,2,3,4 and 5 of water swallow test successively were 44,39,4,0 and 0. Patients with positive aspiration by the first-step(water injection of 0.4 mL)and the second-step(water injection of 2.0 m L)were 16 and 0. Patients with positive aspiration by radionuclide imaging was 35. Comparison of radionuclide imaging, the rate of missed diagnosis applying water swallow test was high 37.3%(31/83). Both the water swallow test and simple two-step swallowing provocation test have poor consistency with radionuclide imaging in the diagnosis of aspiration in patients with acute exacerbation of chronic obstructive pulmonary disease(McNemar consistency test P=0.00).CONCLUSION: There is a high rate of missed diagnosis applying water swallow test and simple two-step swallowing provocation test to diagnosis aspiration in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD),and combined use of multiple assessment methods can reduce the missed diagnosis rate of aspiration.

Bond dissociation energies of carbonyl gold complexes: a new descriptor of ligand effects in gold(i) complexes?

Ligand electronic effects in gold(i) chemistry have been evaluated by means of the experimental determination of M-CO bond dissociation energies for 16 [L-Au-CO]+ complexes, bearing L ligands widely used in gold catalysis. Energy-resolved analyses have been made using tandem mass spectrometry with collision-induced dissociation. Coupled with DFT calculations, this approach enables the quantification of ligand effects based on the LAu-CO bond strength. A further energy decomposition analysis gives access to detailed insights into this bond's characteristics. Whereas small differences are observed between phosphine- and phosphite-containing gold complexes, carbene ligands are shown to stabilize the gold-carbonyl bond much more efficiently.
