Abstract
Previous studies have reported the important roles of long non-coding RNAs (lncRNAs) in acute respiratory distress syndrome (ARDS). Here, we focus on the role and regulatory mechanism of lncRNA SNHG5 in ARDS. LPS was used to induce mice to establish ARDS model in vivo and to induce A549 cells to establish ARDS model in vitro. qRT-PCR was performed to determine the expressions of SNHG5, miR-205, and inflammatory cytokines. MTT assay was applied to detect cell viability. Dual-luciferase reporter (DLR) assay was performed to test the interactions among SNHG5, miR-205 and COMMD1. Western blot was used to detect the protein expression of COMMD1. Lung injury was evaluated by evaluating the score of lung injury, lung wet/dry weight ratio, and myeloperoxidase (MPO) activity. SNHG5 was downregulated, while miR-205 was upregulated in the serum of ARDS patients and lung tissues of LPS-induced mice. Upregulation of SNHG5 or down-regulation of miR-205 inhibited inflammation and promoted the viability of LPS-induced A549 cells. SNHG5 alleviated the lung injury of ARDS mice. MiR-205 was a target of SNHG5 and inversely correlated with SNHG5. COMMD1 was targeted by miR-205, and was positively regulated by SNHG5. MiR-205 mimics or sh-COMMD1 reversed the promoting effect of SNHG5 on cell viability and the suppressing effect of SNHG5 on inflammation in cellular model of ARDS. Meantime, miR-205 mimics reversed the relieving effect of SNHG5 on lung injury in mouse model of ARDS. SNHG5 acted as a sponge for miR-205 to ameliorate LPS-induced ARDS by regulating COMMD1.

Abstract
Recent mass spectrometry maps of the human interactome independently support the existence of a large multiprotein complex, dubbed "Commander." Broadly conserved across animals and ubiquitously expressed in nearly every human cell type examined thus far, Commander likely plays a fundamental cellular function, akin to other ubiquitous machines involved in expression, proteostasis, and trafficking. Experiments on individual subunits support roles in endosomal protein sorting, including the trafficking of Notch proteins, copper transporters, and lipoprotein receptors. Commander is critical for vertebrate embryogenesis, and defects in the complex and its interaction partners disrupt craniofacial, brain, and heart development. Here, we review the synergy between large-scale proteomic efforts and focused studies in the discovery of Commander, describe its composition, structure, and function, and discuss how it illustrates the power of systems biology. Based on 3D modeling and biochemical data, we draw strong parallels between Commander and the retromer cargo-recognition complex, laying a foundation for future research into Commander's role in human developmental disorders.

Abstract
Lamin A, which is encoded by the LMNA gene, regulates gene expression and genome stability through interactions with a variety of proteins. Mutations in LMNA lead to a diverse set of inherited human diseases, collectively referred to as laminopathies. To gain insight into the protein interactions of lamin A, a yeast two-hybrid screen was conducted using the carboxy-terminus of lamin A. The screen identified copper metabolism MURR1 domain-containing 1 (COMMD1) as a novel lamin A binding partner. Colocalization experiments using fluorescent confocal microscopy revealed that COMMD1 colocalized with lamin A in 293 cells. Furthermore, the COMMD1-lamin A protein interaction was also demonstrated in co-immunoprecipitation experiments. Collectively, the present study demonstrated a physical interaction between COMMD1 and lamin A, which may aid to elucidate the mechanisms of lamin A in the aging process.

New use for an old drug: COX-independent anti-inflammatory effects of sulindac in models of cystic fibrosis. Br J Pharmacol 2016; 173:1728-41. [PMID: 26894321 PMCID: PMC4867744 DOI: 10.1111/bph.13464] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2015] [Revised: 02/08/2016] [Accepted: 02/09/2016] [Indexed: 01/14/2023] Open
Abstract
Background and Purpose Pulmonary disease is the main cause of morbidity and mortality in cystic fibrosis (CF) patients due to exacerbated inflammation. To date, the only anti‐inflammatory drug available to CF patients is high‐dose ibuprofen, which can slow pulmonary disease progression, but whose cyclooxygenase‐dependent digestive adverse effects limit its clinical use. Here we have tested sulindac, another non‐steroidal anti‐inflammatory drug with an undefined anti‐inflammatory effect in CF airway epithelial cells. Experimental Approach Using in vitro and in vivo models, we NF‐κB activity and IL‐8 secretion. In HeLa‐F508del cells, we performed luciferase reporter gene assays in order to measure i) IL‐8 promoter activity, and ii) the activity of synthetic promoter containing NF‐κB responsive elements. We quantified IL‐8 secretion in airway epithelial CFBE cells cultured at an air‐liquid interface and in a mouse model of CF. Key Results Sulindac inhibited the transcriptional activity of NF‐κB and decreased IL‐8 transcription and secretion in TNF‐α stimulated CF cells via a cyclooxygenase‐independent mechanism. This effect was confirmed in vivo in a mouse model of CF induced by intra‐tracheal instillation of LPS, with a significant decrease of the induction of mRNA for MIP‐2, following treatment with sulindac. Conclusion and Implications Overall, sulindac decrease lung inflammation by a mechanism independent of cycolooxygenase. This drug could be beneficially employed in CF.

Lappas M. Copper metabolism domain-containing 1 represses the mediators involved in the terminal effector pathways of human labour and delivery. Mol Hum Reprod 2016; 22:299-310. [PMID: 26733542 DOI: 10.1093/molehr/gav075] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2015] [Accepted: 12/22/2015] [Indexed: 12/20/2022] Open
Abstract
STUDY HYPOTHESIS Does Copper Metabolism MURR1 Domain 1 (COMMD1) play a role in regulating the mediators involved in the terminal processes of human labour and delivery? STUDY FINDING COMMD1 plays a critical role in the termination of nuclear factor-κB (NF-κB) activity and the control of pro-inflammatory and pro-labour mediators. WHAT IS KNOWN ALREADY Inflammation and infection are the biggest aetiological factors associated with preterm birth. NF-κB drives the transcription of pro-inflammatory mediators involved in the terminal effector pathways of human labour and delivery. In non-gestational tissues, COMMD1 is a negative regulator of NF-κB-induced inflammation. STUDY DESIGN, SAMPLES/MATERIALS, METHODS The mRNA and/or protein level of COMMD1 was assessed in myometrium (n = 8 per group) and fetal membranes (n = 8 per group) obtained from term non-labouring and labouring women at term, and fetal membranes (n = 8 per group) at preterm with and without histological chorioamnionitis. Primary human myometrial cells were used to determine the effect of pro-inflammatory mediators on COMMD1 level, and the effect of COMMD1 small interfering RNA (siRNA) on pro-labour mediators. Statistical significance was ascribed to a P < 0.05. MAIN RESULTS AND THE ROLE OF CHANCE COMMD1 expression was significantly decreased with spontaneous term labour in myometrium; in fetal membranes with histologically confirmed chorioamnionitis and in myometrial cells treated with pro-inflammatory cytokines interleukin (IL)-1β and tumour necrosis factor (TNF)-α, the bacterial product fibroblast-stimulating lipopeptide and the viral double stranded RNA analogue polyinosinic polycytidilic acid. Loss-of-function studies revealed an increase in inflammation- and infection-induced TNF-α, IL-1α, IL-1β, IL-6, IL-8 and/or monocyte chemoattractant protein-1 mRNA abundance and/or release; and cyclo-oxygenase-2 mRNA level, release of prostaglandin (PG) F2α and mRNA level of the PGF2α receptor FP. In addition, siRNA knockdown of COMMD1 was associated with significantly increased NF-κB activation as evidenced by increased IL-1β-induced IκB-α protein degradation and NF-κB DNA binding activity. LIMITATIONS, REASONS FOR CAUTION The conclusions are based on in vitro experiments with cells isolated from myometrium. Animal models, however, will be required to establish whether COMMD1 activators can prevent spontaneous preterm birth in vivo. WIDER IMPLICATIONS OF THE FINDINGS The control of COMMD1 activation may provide an alternative therapeutic strategy for reducing the release of pro-labour mediators in spontaneous preterm labour.
