Abstract
Chemotherapy remains the mainstay of treatment for the lymphoma patient population, despite its relatively poor therapeutic results, high toxicity, and low specificity. With the advancement of biotechnology, the significance of drug-loading biomimetic materials in the medical field has become increasingly evident, attracting extensive attention from the scientific community and the pharmaceutical industry. Given that they can cater to the particular requirements of lymphoma patients, drug-loading biomimetic materials have recently become a potent and promising delivery approach for various applications. This review mainly reviews the recent advancements in the treatment of tumors with biological drug carrier-loaded drugs, outlines the mechanisms of lymphoma development and the diverse treatment modalities currently available, and discusses the merits and limitations of biological drug carriers. What is more, the practical application of biocarriers in tumors is explored by providing examples, and the possibility of loading such organisms with antilymphoma drugs for the treatment of lymphoma is conceived.

Abstract
The bunch length in a linac driven Free Electron Laser (FEL) is a major parameter to be characterized to optimize the final accelerator performance. In linear machines, this observable is typically determined from the beam imaged on a screen located downstream of a Transverse Deflecting Structure (TDS) used to impinge a time dependent kick along the longitudinal coordinate of the beam. This measurement is typically performed during the machine setup and only sporadically to check the beam duration, but it cannot be continuously repeated because it is time consuming and invasive. A non-invasive method to determine the electron bunch length has already been presented in the past. This method is based on the analysis of the synchrotron radiation light spot emitted by the bunch passing through a magnetic chicane, provided that the energy chirp impinged on the bunch by the upstream radio frequency structures is known. In order to overcome a systematic discrepancy affecting the synchrotron radiation monitor based results compared to the absolute TDS based ones, we implemented and optimized a machine learning approach to predict the bunch length downstream of the two SwissFEL compression stages-from about 10 fs up to about 2 ps-as well as the beam longitudinal profile at the first one.

Abstract
Xerocomoideae is an ecologically and economically important Boletaceae subfamily (Boletales) comprising 10 genera. Although many studies have focused on Xerocomoideae in China, the diversity, taxonomy and molecular phylogeny still remained incompletely understood. In the present study, taxonomic and phylogenetic studies on Chinese species of Xerocomoideae were carried out by morphological examinations and molecular phylogenetic analyses. Eight genera in Xerocomoideae, viz. Aureoboletus, Boletellus, Heimioporus, Hemileccinum, Hourangia, Phylloporus, Pulchroboletus, and Xerocomus were confirmed to be distributed in China; 97 species of the subfamily were accepted as being distributed in China; one ambiguous taxon was tentatively named Bol. aff. putuoensis; two synonyms, viz. A. marroninus and P. dimorphus were defined. Among the Chinese accepted species, 13 were newly described, viz. A. albipes, A. conicus, A. ornatipes, Bol. erythrolepis, Bol. rubidus, Bol. sinochrysenteroides, Bol. subglobosus, Bol. zenghuoxingii, H. squamipes, P. hainanensis, Pul. erubescens, X. albotomentosus, and X. fuscatus, 36 known species were redescribed, and the other 48 species were reviewed. Keys to accepted species of Aureoboletus, Boletellus, Heimioporus, Hemileccinum, Hourangia, Phylloporus, and Xerocomus in China were also provided.

Abstract
The infectious spleen and kidney necrosis virus (ISKNV) is a highly lethal virus, which has brought significant losses to aquaculture. Therefore, a new vaccine against ISKNV with high efficiency, safety and convenience must be developed. While baculoviruses are more commonly used as protein expression systems for vaccine antigen production, this paper used baculovirus technology to develop a live-vector vaccine, BacMCP, which contains the coding sequence of the major capsid protein (MCP) (GenBank accession no. AF371960) of ISKNV and is driven by a CMV promoter. Real-time PCR and immunofluorescence showed that the MCP gene was successfully delivered to and expressed in fish cells and tissues inoculated with BacMCP. Immune-related gene (IgM, TGF-β, IL-1, IL-8, TNF-α) expression was induced in BacMCP-treated groups of largemouth bass compared with control groups. Specific antibodies could be detected in the serum of BacMCP injection-vaccinated largemouth bass by ELISA. After injection or immersion vaccination with BacMCP for 21 days, largemouth bass were infected with ISKNV. The immune effect of the injected immunization on fish in different sizes was evaluated. The vaccine efficacy of injection-vaccinated bass was 100% in small bass and 85.7% in large bass. The vaccine efficacy of immersion-vaccinated small bass was 77.3%. This study suggested that BacMCP can be used as a vector-based vaccine candidate to prevent the diseases caused by ISKNV infection.

Abstract
Multifocal microscopy (MUM), a technique to capture multiple fields of view (FOVs) from distinct axial planes simultaneously and on one camera, was used to perform micro-particle image velocimetry (µPIV) to reconstruct velocity and shear stress fields imposed by a liquid flowing around a cell. A diffraction based multifocal relay was used to capture images from three different planes with 630 nm axial spacing from which the axial positions of the flow-tracing particles were calculated using the image sharpness metric. It was shown that MUM can achieve an accuracy on the calculated velocity of around (0.52 ± 0.19) µm/s. Using fixed cells, MUM imaged the flow perturbations at sub-cellular level, which showed characteristics similar to those observed in the literature. Using live cells as an exemplar, MUM observed the effect of changing cell morphology on the local flow during perfusion. Compared to standard confocal laser scanning microscope, MUM offers a clear advantage in acquisition speed for µPIV (over 300 times faster). This is an important characteristic for rapidly evolving biological systems where there is the necessity to monitor in real time entire volumes to correlate the sample responses to the external forces.

Abstract
Cyprinid herpesvirus 2 (CyHV-2) has caused great losses to the gibel carp (Carassius auratus gibelio) industry. Previous studies showed that certain DNA viruses can encode circular RNAs (circRNAs) to regulate virus infection, which provides new clues for the treatment of viral disease. Whether CyHV-2 can encode circRNAs is still unknown. Here, 10 CyHV-2-derived circRNAs were identified, and the function of circ-udg, a circRNA derived from the CyHV-2 uracil DNA glycosylase (udg) gene, was studied. Although the expression level of circ-udg was lower than that of the parental gene, udg, its expression level was elevated in tandem with the proliferation of CyHV-2 and udg. In vitro experiments confirmed that circ-udg could promote the proliferation of CyHV-2. Moreover, circ-udg could encode a truncated UDG protein consisting of 147-amino-acid residues (termed circ-udg-P147). Both UDG and circ-udg-P147 were found to promote CyHV-2 proliferation, but the promoting effect of circ-udg on CyHV-2 proliferation was attenuated after circ-udg lost the ability to encode circ-udg-P147. Also, circ-udg-P147 could not change the transcription level of the udg gene. Interestingly, the UDG protein level was increased by circ-udg-P147. These results deepen the understanding of the genetic information carried by the genome of CyHV-2 and provide a new target for the treatment of gibel carp bleeding disease caused by CyHV-2. IMPORTANCE The outbreak of C. auratus gibelio gill hemorrhagic disease caused by CyHV-2 brought great losses to the gibel carp industry. Therefore, exploring the interaction between CyHV-2 and host and the molecular mechanism of viral infection is of great significance in preventing and treating the gibel carp gill hemorrhagic disease. Although some progress has been made in the study of CyHV-2, the mechanism of interaction between CyHV-2 and crucian carp is still unclear. In this study, we found that CyHV-2 can encode circRNA to regulate virus replication. Our study provides novel information on CyHV-2 functional genomics, a reference for research into the circRNA of other viruses, and theoretical guidance for preventing and treating gibel carp bleeding disease.

Abstract
To date, some DNA viruses and single-stranded RNA viruses have been found to generate circRNAs. However, the reports on circRNAs produced by double-stranded RNA viruses are very limited. In this study, Bombyx mori cypovirus (BmCPV), a typical double-stranded RNA virus belonging to the Reoviridae, was demonstrated to generate viral circRNAs (vcircRNAs) and a vcircRNA_000048 whose sequence corresponds with the region 164-1245 nt on the BmCPV genomic dsRNA S5 segment (GQ294468.1) was validated by PCR, Sanger sequencing, reverse transcription-rolling circle amplification, and Northern blotting. Furthermore, we verified that vcircRNA_000048 translates a micropeptide vsp21 with 21 amino acid residues in an IRES-dependent manner, and vsp21 attenuates the viral replication. These findings provided a novel clue to understanding the regulation of viral multiplication and interaction of reovirus with the host.

Abstract
β-Arrestin 2 is known to be a widely distributed adaptor protein in mammals but its function has never been reported in Lepidoptera insects. Herein, the β-Arrestin 2 (BmArrestin 2) gene from silkworm was cloned and characterized. The spatiotemporal expression level of BmArrestin 2 was highest in the gonads at the 3rd day of 5th instar, whereas the highest and lowest abundance of BmArrestin 2 were identified in the tracheal and testis, respectively. BmArrestin 2 is mainly distributed in the cytoplasm. Furthermore, in BmN cells,overexpression of BmArrestin 2 promoted Bombyx mori nucleopolyhedrovirus (BmNPV) and B. mori cytoplasmic polyhedrosis virus (BmCPV) replication as the increment of the concentration of plasmid transfection, whereas silencing the gene with specific siRNA inhibited viral replication. Replication of BmNPV and BmCPV also was weakened using BmArrestin 2 antiserum as the increment of the concentration. Immunofluorescent staining revealed the invasion of recombinant BmNPV or BmCPV was decreased after blocking endogenous BmArrestin 2. On the other hand, BmArrestin 2 co-localizes with recombinant BmNPV and BmCPV virions in BmN cells. These results suggest that BmArrestin 2 may represent a novel target for antiviral strategies, as it is an adaptor protein that plays a key role in virus replication.

Abstract
Circular DNAs derived from single-stranded RNA viruses play important roles in counteracting viral infection. However, whether double-stranded RNA viruses generate functional circular DNAs is still unknown. Using circDNA sequencing, divergent PCR, DNA in situ hybridization and rolling circular amplification, we presently confirmed that in silkworm, Bombyx mori cytoplasmic polyhedrosis virus (BmCPV), a double-stranded RNA virus belonging to cypovirus, is prone to produce a BmCPV-derived circular DNA termed as vcDNA-S7. We have also found that vcDNA-S7 formation is mediated by endogenous reverse transcriptase (RT), and the proliferation of BmCPV can be inhibited by vcDNA-S7 in vitro and in vivo. Moreover, we have discovered that the silkworm RNAi immune pathway is activated by vcDNA-S7, while viral small interfering RNAs (vsiRNAs) derived from transcribed RNA by vcDNA-S7 can be detected by small RNA deep sequencing. These results suggest that BmCPV-derived vcDNA-S7, mediated by RT, can serve as a template for the biogenesis of antiviral siRNAs, which may lead to the repression of BmCPV infection. To our knowledge, this is the first demonstration that a circular DNA, produced by double stranded RNA viruses, is capable of regulating virus infection.

Abstract
The mechanism by which infection by Bombyx mori cytoplasmic nucleopolyhedrosis virus (BmCPV) causes autophagy has not been studied in detail. Herein we have observed by electron microscopy that infection with BmCPV causes autophagosome and mitochondrial structure damage in Bombyx mori midgut. In BmN cells infected with BmCPV and expressing eGFP-LC3, fluorescence spots and LC3-II levels increased, suggesting that BmCPV infection causes autophagy. Autophagy inducer rapamycin (Rap) and autophagy inhibitor 3-methyladenine (3-MA) were used to monitor the effects of mitophagy on BmCPV proliferation. It was found BmCPV proliferation to be promoted by mitophagy. Transient transfection experiments in cultured BmN cells showed that mitophagy can be triggered by expression of BmCPV structural protein VP4. Moreover, VP4 caused upregulation of p-Drp1, PINK1 and Parkin proteins in the mitophagy pathway and downregulation of mitochondrial membrane protein Tom20. Furthermore, interaction between VP4 with Tom40 was confirmed by Co-IP, western blot and colocalization experiment, and overexpression of Tom40 reduce the level of mitochondrial autophagy induced by VP4. These results suggested that VP4 induced PINK1-Parkin-mediated mitophagy interacting with Tom40. These findings deepen our understanding of the interaction between BmCPV and silkworm and also provide a molecular target for screening anti-BmCPV drugs.

Abstract
Postoperative fatigue (POF) is the most common and long-lasting complication after surgery, which brings heavy burden to individuals and society. Recently, hastening postoperative recovery receives increasing attention, but unfortunately, the mechanisms underlying POF remain unclear. Propofol is a wildly used general anesthetic in clinic, and inspired by the rapid antidepressant effects induced by ketamine at non-anesthetic dose, the present study was undertaken to investigate the anti-fatigue effects and underlying mechanisms of propofol at a non-anesthetic dose in 70% hepatectomy induced POF model in rats. We first showed here that single administration of propofol at 0.1 mg/kg ameliorated acute POF in hepatectomy induced POF rats. Based on metabonomics analysis, we hypothesized that propofol exerted anti-fatigue activity in POF rats by facilitating free fatty acid (FFA) oxidation and gluconeogenesis. We further confirmed that propofol restored the deficit in FFA oxidation and gluconeogenesis in POF rats, as evidenced by the elevated FFA utilization, acetyl coenzyme A content, pyruvic acid content, phosphoenolpyruvic acid content, hepatic glucose output and glycogen storage. Moreover, propofol stimulated glucagon secretion and up-regulated expression of cAMP-response element binding protein (CREB), phosphorylated CREB, peroxlsome prolifeator-activated receptor-γ coactivator-1α (PGC-1α), phosphoenolpyruvate carboxykinade1 and carnitine palmitoltransferase 1A. In summary, our study suggests for the first time that propofol ameliorates acute POF by promoting glucagon-regulated gluconeogenesis via CREB/PGC-1α signaling and accelerating FFA beta-oxidation.

Abstract
Bombyx mori cypovirus (BmCPV), a member of the family Reoviridae, is a model of Cypovirus, has a 10 segmented double-stranded RNA genome. However, so far, only one viral small peptide vSP27 with negative regulation on viral infection was identified; the mechanisms underlying host-BmCPV interaction are still unknown. Here, we identified that vSP27 was translated from a BmCPV derived circular RNA (circRNA-vSP27). Subsequently, results showed that vSP27 induced generation of ROS activated the NF-κB signaling pathway, induced the expression of antimicrobial peptides, and suppressed BmCPV infection. On the other hand, we identified a nuclear protein Akirin that could hijack vSP27, positively regulate the NF-κB pathway, and lead to inhibiting the viral infection. Altogether, our data suggested that BmCPV derived circRNA-vSP27 with small peptide translation activity may be employed by the host immunity in defense against the BmCPV infection.

Abstract
Hepatitis B virus (HBV) produces circular RNA (circRNA), whose functions have not yet been clearly elucidated. In this study, a novel circRNA HBV_circ_1 produced by HBV was identified in HBV-positive HepG2.2.15 cells and HBV-related hepatocellular carcinoma (HCC) tissue (HCCT). Microarray analysis of 68 HCCT samples showed that HBV_circ_1 abundance was significantly higher than that in paracancerous tissues. In addition, survival rate of HBV_circ_1-positive patients was significantly lower compared with HBV_circ_1-negative patients. Transient expression indicated that HBV_circ_1 enhanced cell proliferation, migration, and invasion and inhibited apoptosis in vitro. Furthermore, ectopical HBV_circ_1 expression increased tumor size in vivo. HBV_circ_1 was confirmed to interact with cyclin-dependent kinase 1 (CDK1) to regulate cell proliferation. These results suggest that HCC progression may be promoted by interaction of HBV_circ_1 with CDK1. Our data not only showed a novel clue to understand carcinogenesis and progress of HBV-related HCC but also provided a new target for the development of therapeutic drugs.

Abstract
Exosomes are small membrane-enclosed vesicles secreted by various types of cells. Exosomes not only participate in different physiological processes in cells, but also involve in the cellular responses to viral infection. Grass carp reovirus (GCRV) is a non-enveloped virus with segmented, double-stranded RNA genome. Nowadays, the exact role of exosomes in regulating the life cycle of GCRV infection is still unclear. In this study, the exosomes secreted from Ctenopharyngodon idellus kidney (CIK) cells infected or uninfected with GCRV were isolated, and the differential protein expression profiles were analyzed by proteomic technologies. A total of 1297 proteins were identified in the isolated exosomes. The differentially abundant proteins were further analyzed with functional categories, and numerous important pathways were regulated by exosomes in GCRV-infected CIK cells. These exosomal proteins were estimated to interact with the genes (proteins) of the top 10 most enriched signaling pathways. Furthermore, GW4869 exosome inhibitor suppressed the expression level of VP7 in GCRV-infected cells, suggesting that exosomes play a crucial role in the life cycle of GCRV infection. These findings could shed new lights on understanding the functional roles of exosomes in the cellular responses to GCRV infection.

Simple Summary The cause of Chinese mitten crab Eriocheir sinensis hepatopancreas necrosis disease (HPND) remains a mystery. In this study, metatranscriptomics sequencing was conducted to characterize the changes in the structure and gene expression of hepatopancreatic flora of crabs with and without typical symptoms of HPND; an imbalance of hepatopancreatic flora can be found in the crab with HPND, and the detected microbial taxa decreased, whereas the prevalence of Spiroplasma eriocheiris significantly increased in the hepatopancreatic flora of crabs with typical symptoms of HPND, and the relative abundances of the virus and microsporidia in crabs with HPND were very low and did not increase with disease progression. The differentially-expressed genes (DEGs) in hepatopancreatic flora between crabs with and without HPND were enriched ribosome, retinol metabolism, and biosynthesis of unsaturated fatty acid KEGG pathways. These results suggested that an imbalance of hepatopancreatic flora was associated with crab HPND, and the enriched pathways of DEGs were associated with the pathological mechanism of HPND. Abstract Hepatopancreas necrosis disease (HPND) of the Chinese mitten crab Eriocheir sinensis causes huge economic loss in China. However, the pathogenic factors and pathogenesis are still a matter of dissension. To search for potential pathogens, the hepatopancreatic flora of diseased crabs with mild symptoms, diseased crabs with severe symptoms, and crabs without visible symptoms were investigated using metatranscriptomics sequencing. The prevalence of Absidia glauca and Candidatus Synechococcus spongiarum decreased, whereas the prevalence of Spiroplasma eriocheiris increased in the hepatopancreatic flora of crabs with HPND. Homologous sequences of 34 viral species and 4 Microsporidian species were found in the crab hepatopancreas without any significant differences between crabs with and without HPND. Moreover, DEGs in the hepatopancreatic flora between crabs with severe symptoms and without visible symptoms were enriched in the ribosome, retinol metabolism, metabolism of xenobiotics by cytochrome P450, drug metabolism—cytochrome P450, biosynthesis of unsaturated fatty acids, and other glycan degradation. Moreover, the relative abundance of functions of DEDs in the hepatopancreatic flora changed with the pathogenesis process. These results suggested that imbalance of hepatopancreatic flora was associated with crab HPND. The identified DEGs were perhaps involved in the pathological mechanism of HPND; nonetheless, HPND did not occur due to virus or microsporidia infection.

Abstract
Encapsulation of antigens within protein microcrystals (polyhedra) is a promising approach for the stable delivery of vaccines. In this study, a vaccine was encapsulated into polyhedra against cyprinid herpesvirus II (CyHV-2). CyHV-2 typically infects gibel carp, Carassius auratus gibelio, causing gill hemorrhagic disease. The vaccine was constructed using a codon-optimized sequence, D4ORF, comprising the ORF72 (region 1–186 nt), ORF66 (region 993–1197 nt), ORF81 (region 603–783 nt), and ORF82 (region 85–186 nt) genes of CyHV-2. The H1-D4ORF and D4ORF-VP3 sequences were, respectively, obtained by fusing the H1-helix sequence (region 1–90 nt) ofBombyx mori cypovirus(BmCPV) polyhedrin to the 5′ terminal end of D4ORF and by fusing a partial sequence (1–279 nt) of the BmCPV VP3 gene to the 3′ terminal end of D4ORF. Furthermore, BmNPV-H1-D4ORF-polh and BmNPV-D4ORF-VP3-polh recombinant B. mori nucleopolyhedroviruses (BmNPVs), belonging to the family Baculoviridae, and co-expressing BmCPV polyhedrin and H1-D4ORF or D4ORF-VP3, were constructed. H1-D4ORF and D4ORF-VP3 fusion proteins were confirmed to be encapsulated into recombinant cytoplasmic polyhedra by Western blotting. Degradation of vaccine proteins was assessed by SDS-PAGE, and the results showed that the encapsulated vaccine proteins in polyhedra could be protected from degradation. Furthermore, when gibel carp were vaccinated with the purified polyhedra from BmNPV-H1-D4ORF-polh and BmNPV-D4ORF-VP3-polh via injection, the antibody titers in the serum of the vaccinated fish reached 1:6400–1:12,800 at 3 weeks post-vaccination. Therelative percentage of survival of immunized gibel carp reached 64.71% and 58.82%, respectively, following challenge with CyHV-2. These results suggest that incorporating vaccine protein into BmCPV polyhedra may be a novel approach for developing aquaculture microencapsulated vaccines.

Abstract
OBJECTIVE Glioma is a highly aggressive and lethal brain tumor. Anesthetics have been shown to have important effects on the biological characteristics of cancer cells. Nevertheless, the molecular mechanism of anesthetic-mediated glioma cells progression remains unclear. MATERIALS AND METHODS Sevoflurane (sev) was employed to treat glioma cells. The biological characteristics (viability, colony formation, apoptosis, cell cycle, migration, and invasion) of glioma cells were determined via Cell Counting Kit-8 (CCK-8), cell colony formation, flow cytometry, PI cytometry, or transwell assays. The protein levels of Cell Cycle Dependent Kinase (CDK) 2, CDK4, E-cadherin, N-cadherin, Vimentin, and Transforming Growth Factor Beta (TGFB) induced factor homeobox 2 (TGIF2) were assessed through Western blot analysis. Glucose consumption and lactate production were measured using special commercial kits. The expression of circular RNA has_circ_0012129 (circ_0012129) and miR-761 was detected via quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The relationship between circ_0012129 or TGIF2 and miR-761 was verified with Dual-Luciferase reporter assay. Sevoflurane-mediated molecular mechanisms have been confirmed via xenograft assay. RESULTS Sevoflurane suppressed viability, colony formation, cell cycle, migration, and invasion and promoted apoptosis of glioma cells in vitro, and impeded tumor growth in vivo. Circ_0012129 and TGIF2 were downregulated and miR-761 was upregulated in sevoflurane-treated glioma cells. Circ_0012129 elevation abolished sevoflurane-mediated biological characteristics of glioma cells. MiR-761 served as target for circ_0012129 and miR-761 targeted TGIF2. Moreover, both miR-761 overexpression and TGIF2 suppression restored circ_0012129 enhancement-mediated biological characteristics of sevoflurane-treated glioma cells. CONCLUSIONS Sevoflurane mediated the progression of glioma via regulating the circ_0012129/miR-761/TGIF2 axis.

Abstract
OBJECTIVE The aim of this study was to explore the effect of neurotrophin-3 (NT-3) on the repair of spinal cord injury (SCI) through the mitogen-activated protein kinase (MAPK) signaling pathway. MATERIALS AND METHODS The rat model of SCI was first successfully established using the impactor (SCI group). Meanwhile, control group and NT-3 treatment group were set up as well. Basso-Beattie-Bresnahan (BBB) score was given and blood, and spinal cord tissues were collected from rats. Subsequently, serum indexes were detected, including glucose (Glu), creatinine (Cr), K+, Na+, the content of interleukin-6 (IL-6), IL-1β, tumor necrosis factor-β (TNF-β), and the level of myeloperoxidase (MPO). Moreover, the morphological changes were observed via hematoxylin-eosin (HE) staining. The gene and protein expressions of glial fibrillary acidic protein (GFAP) and MAPK were determined through Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and Western blotting, respectively. Furthermore, the effect of the MAPK signaling pathway on SCI was comprehensively observed. RESULTS In SCI group, the rats could not crawl autonomously with the loss of motor function and paraplegia. Meanwhile, the levels of Glu, Cr, Na+, IL-6, IL-1β, TNF-β, and MPO were all significantly up-regulated. According to the results of HE staining, spinal nerve fibers disappeared with significant syringomyelia in SCI group. Meanwhile, the aggregation of nerve fibers was observed without apparent tissue bleeding, edema, and cell deformation in NT-3 group. QRT-PCR results demonstrated that SCI group showed remarkably higher levels of GFAP, MAPK, and c-Jun N-terminal kinase (JNK) (p<0.05), while it showed a markedly lower level of ERK2 than NT-3 group (p<0.05). In NT-3 group, the protein expression of MAPK in myocardial tissues was remarkably lower than that of SCI group (p<0.05). CONCLUSIONS NT-3 can inhibit the MAPK signaling pathway, thereby promoting the repair of SCI.

Abstract
A large number of circular RNAs (circRNAs) have been found in different organisms; however, their function in the regulation of histone modification remains unknown. In this study, we found that the circRNA circEgg, cyclized by the 9th-13th exon of Bombyx mori histone-lysine N-methyltransferase eggless (BmEgg) gene, mainly distributes in the cytoplasm, its expression levels changed with silkworm developmental stages, and the linear transcript level of the BmEgg gene was decreased when circEgg was overexpressed. Moreover, circEgg was found to repress histone H3 lysine 9 methylation (H3K9me3), promote histone H3 lysine 9 acetylation (H3K9ac), and positively regulate histone deacetylase (HDAC) Rpd3 (BmHDAC Rpd3) gene expression by sponging the microRNA bmo-miR-3391-5p. Furthermore, circEgg encodes a circEgg-P122 protein which appears to inhibit H3K9me3. These results suggest that circEgg regulates histone modification by sponging bmo-miR-3391-5p and encoding circEgg-P122 protein. To our knowledge, this is the first report showing that a circRNA produced by BmEgg plays an important role in histone epigenetic modification.

Abstract
BACKGROUND The protective efficacy of avian influenza virus (AIV) vaccines is unsatisfactory due to the presence of various serotypes generated by genetic reassortment. Thus, immunization with a polyantigen chimeric epitope vaccine may be an effective strategy for protecting poultry from infection with different AIV subtypes. METHODS Baculovirus has recently emerged as a novel and attractive gene delivery vehicle for animal cells. In the present study, a recombinant baculovirus BmNPV-CMV/THB-P10/CTLT containing a fused codon-optimized sequence (CTLT) of T lymphocyte epitopes from H1HA, H9HA, and H7HA AIV subtypes, and another fused codon-optimized sequence (THB) of Th and B cell epitopes from H1HA, H9HA, and H7HA AIV subtypes, driven by a baculovirus P10 promoter and cytomegalovirus CMV promoter, respectively, was constructed. RESULTS Western blotting and cellular immunofluorescence demonstrated that the CTLT (THB) can be expressed in rBac-CMV/THB-P10/CTLT-infected silkworm cells (mammalian HEK293T cells). Furthermore, the recombinant virus, rBac-CMV-THB-CTLT, was used to immunize both chickens and mice. CONCLUSIONS The results of an indirect ELISA, immunohistochemistry, and T lymphocyte proliferation assay indicated that specific humoral and cellular responses were detected in both chicken and mice. These results suggest that rBac-CMV/THB-P10/CTLT can be developed as a potential vaccine against different AIV subtypes.

Abstract
The grass carp accounts for a large proportion of aquacultural production in China, but the hemorrhagic disease caused by grass carp reovirus (GCRV) infection often causes huge economic losses to the industry. Interleukin 17 (IL-17) is an important cytokine that plays a critical role in the inflammatory and immune responses. Although IL-17 family members have been extensively studied in mammals, our knowledge of the activity of IL-17 proteins in teleosts in response to viral infection is still limited. In this study, the role of IL-17 in GCRV infection and its mechanism were investigated. The expression levels of IL-17AF1, IL-17AF2, and IL-17AF3 in Ctenopharyngodon idella kidney (CIK) cells gradually increased from 6 h after infection with GCRV. The nuclear translocation of p65, which acts in the NF-κB signaling pathway, was also increased by GCRV infection. The overexpression of IL-17AF1, IL-17AF2, or IL-17AF3 also promoted the nuclear translocation of p65 and the levels of phospho-IκBα in CIK cells, and reduced the expression of the viral structural protein VP7. An NF-κB signal inhibitor abolished the inhibition of GCRV infection by IL-17 proteins. These results suggested that the NF-κB signaling pathway was activated by the overexpression of IL-17 proteins, resulting in the inhibition of viral infection. In conclusion, in this study, we demonstrated that IL-17AF1, IL-17AF2, and IL-17AF3 acted as immune cytokines, exerting an antiviral effect by activating the NF-κB signaling pathway.

Abstract
Bombyx mori nucleopolyhedrovirus (BmNPV) is one of the most serious pathogens in sericulture and causes huge economic loss annually. The roles of N6-methyladenosine (m6A) modification in silkworms following BmNPV infection are currently unclear. Here, methylated RNA immunoprecipitation with next-generation sequencing were applied to investigate the m6A profiles in silkworm midgut following BmNPV infection. A total of 9144 and 7384 m6A peaks were identified from the BmNPV-infected (TEST) and uninfected silkworm midguts (CON), respectively, which were distributed predominantly near stop codons. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of common m6A peaks in nuclear genes revealed that these m6A-related transcripts were associated with crucial signaling pathways. Comparative transcriptome analysis showed that 1221 differential expressed m6A peaks were identified between TEST and CON, indicating that m6A modification is regulated following BmNPV infection. GO and KEGG pathway analysis of the differentially expressed m6A peaks showed their association with signal transduction, translation, and degradation. To understand further the effect of the m6A machinery on virus infection, expression levels of m6A-related genes were altered in silencing and overexpression experiments. Expression of viral structural protein VP39 was increased in BmN cells by siRNA-mediated depletion of methyltransferase-like (METTL) enzyme genes (BmMETTL3, BmMETTL14) and cytoplasmic YTH-domain family 3 (BmYTHDF3), while the reverse results were found after overexpression of the m6A-related enzymes in BmN cells. Overall, m6A modification might be a novel epigenetic mechanism that regulation BmNPV infection and interference with this mechanism may provide a novel antiviral strategy for preventing BmNPV disease.

Abstract
Circular RNAs (circRNAs) with regulatory potency activity was identified from varieties of species. Crucian carp (Carassius auratus gibelio) is one of the most freshwater aquaculture species in China. Every year, huge economic damage to the farming was caused by the virus and bacterial infection. Until now, there is any information about circRNA reported from the Crucian carp. In this study, the expression pattern of circRNA in Crucian carp was investigated with transcriptomic analysis. The results showed that only 37 circRNAs were identified from the Crucian carp, and these circRNAs biogenesis was formed with canonical GU-AG splicing mechanism with unevenly distributed on the chromosomes. Wherein, most of the circRNAs were derived from the sense overlapping strategy. Reverse transcript PCR and Sanger sequencing data indicated that these circRNAs were existed authenticity in Crucian carp. The bioinformatics analysis indicated that circRNAs identified from the Crucian carp with potential miRNA sponge regulate the expression level of mRNAs. GO annotation and KEGG pathway analysis of these circRNAs showed that more than 20% circRNAs were related with catalytic activity and binding in the category of molecular function, and these circRNAs were enriched in 9 signaling pathways, such as, Wnt signaling pathway, MAPK signaling pathway, Ubiquitin mediated proteolysis et al. 220 mRNAs would be regulated by the circRNAs via miRNAs mediation. These target mRNAs were further analyzed with functional annotation and KEGG analysis. GO annotation analysis showed that several genes were related with function of nucleotide binding, transcription regulatory activity. KEGG pathway analysis showed that 5 genes were enriched in the pathway of Endocytosis. The circRNA-miRNA-mRNA regulation network indicated that one miRNA can link one or more circRNA and one or more mRNA. Overall, these results will not only help us to further understand the novel RNA transcripts in Crucian carp, but also provide the novel clue to investigate the interaction between host and pathogens from this novel circRNA molecule.

Abstract
Transmissible gastroenteritis virus (TGEV) causes great economic loss to swine industry worldwide. Vaccination is an important method to control the TGEV infection. In this study, a TGEV oral vaccine was generated by transferring a eukaryotic expression recombinant plasmid carrying the SAD (A and D antigenic sites of the S protein) epitope of TGEV into a swine-origin Lactobacillus acidophilus (L. acidophilus). In orally immunized BALB/c mice, the TGEV L. acidophilus oral vaccine induced significantly higher level of SIgA antibodies specific to TGEV compared with the mice immunized with a commercial inactivated TGEV vaccine and similar levels of IgG specific to TGEV as the inactivated vaccine. Furthermore, the TGEV L. acidophilus oral vaccine induced higher levels of IFN-γ, which suggested that the vaccine was able to induce immune response. In brief, this novel TGEV L. acidophilus oral vaccine could induce high levels of both mucosal and humoral immune responses, which has a potential to be used in the pig industries in the future. Keywords: transmissible gastroenteritis virus (TGEV); live L. acidophilus oral vaccine; SIgA antibody; IgG antibody; IFN-γ; IL-4.

Abstract
Cyprinid herpesvirus II (CyHV-2) is highly contagious and pathogenic to Carassius auratus gibelio (gibel carp), causing enormous economic losses in aquaculture in Yancheng city, Jiangsu province, China; however, to date, there is no effective way to protect C. auratus gibelio from CyHV-2 infection. In this study, a recombinant baculovirus vector vaccine, BacCarassius-D4ORFs, containing a fused codon-optimized sequence D4ORFs comprising the ORF72 (region 1-186 nt), ORF66 (region 993-1197 nt), ORF81 (region 603-783 nt) and ORF82 (region 85-186 nt) genes of CyHV-2, driven by a Megalobrama amblycephala β-actin promoter, was constructed. Then, qPCR, Western blotting and immunofluorescence assays showed that the fused gene D4ORFs was successfully delivered and expressed in fish cells or tissues by transduction with BacCarassius-D4ORFs. The fused gene D4ORFs could not be detected by PCR in the C. auratus gibelio injected with BacCarassius-D4ORFs after 7 weeks. Specific antibody against ORF72 could be detected in the serum of vaccinated C. auratus gibelio by injection with BacCarassius-D4ORFs. Furthermore, when C. auratus gibelio were vaccinated with BacCarassius-D4ORFs via the oral or injection route, followed by challenge with CyHV-2, the relative survival rate of immunized C. auratus gibelio reached 59.3% and 80.01%, respectively. These results suggested that BacCarassius-D4ORFs has the potential to be used as a vector-based vaccine for the prevention and treatment of disease caused by CyHV-2 infection.

Abstract
Objective: To analyze the prevalence of silicosis in the militias with contribution to the former Xiangyu Railway construction in Nanchong, China, from 2008 to 2017, and to provide a scientific basis for the future development of pneumoconiosis prevention and control strategies based on the current status. Methods: A database was established for the data of 11863 militias with contribution to the former Xiangyu Railway construction in Nanchong, China, who attended our hospital from 2008 to 2017, including 11485 males (96.81%) and 378 females (3.19%). The SPSS 17.0 software was used to analyze the differences in the detection rate of silicosis between militias with different sexes or those with different job types, as well as the age, length of service, and regional distribution of patients. Results: Of the 11863 railway militias in Nanchong, 3169 (26.71%) were diagnosed with silicosis, including 2761 (87.12%) in stage I, 359 (11.33%) in stage II, and 49 (1.55%) in stage III; the males had a significantly higher detection rate of silicosis than the females (χ(2)=64.496, P<0.05); there was a significant difference in the detection rate of silicosis between the militias with different job types (χ(2)=856.839, P<0.05). There were significant differences in the mean age of diagnosis and the mean length of service between the patients with different stages of silicosis (F=4.944, P<0.05; F=3.174, P<0.05). There was a significant difference in the number of militia patients with silicosis between different areas of Nanchong (χ(2)=843.330, P<0.05). Conclusion: The prevalence of silicosis is relatively high among the militias with contribution to the former Xiangyu Railway. It is necessary to strengthen the occupational health monitoring of patients, actively treat and prevent complications, and improve the quality of life of patients.

Abstract
Bombyx mori cypovirus (BmCPV) is one of the most infectious pathogen in sericulture and a member of the family Reoviridae. It specifically infects the midgut of silkworm. The BmCPV genome consists of 10 dsRNAs segments (S1-S10), which have generally been assumed to be monocistronic. In this study, a small open reading frame encoding the peptide S5-sORF, containing 27 amino acid residues, was predicted in a region of the negative (-) strand of BmCPV segment S5. An immunofluorescence assay detected S5-sORF in the cytoplasm and nuclei of BmCPV-infected cells, and it was also detected in the virion with western blotting, suggesting that S5-sORF may be assembled into the BmCPV virion. Viral gene expression was inhibited by overexpressed S5-sORF, and viral multiplication was dose-dependently suppressed by the S5-sORF peptide. A viable recombinant virus, BmCPV-S5-sORFmut, in which the start codon (ATG) of S5-sORF was mutated to a stop codon (TGA), was generated with reverse genetics. The proliferation of BmCPV was increased by the abolition of S5-sORF expression. Furthermore, the RNA transcript of S5-sORF and small peptide of S5-sORF were involved in BmCPV replication. The expression of genes related to the innate immune pathways and apoptosis in the silkworm were not significantly affected by S5-sORF overexpression. Our results suggest that a viral nucleotide sequence is utilized by the host to generate an antiviral peptide, which may be a novel strategy protecting the host from viral infection.

Abstract
Background In our previous study, we identified four isoforms of the Bmovo gene, Bmovo-1, Bmovo-2, Bmovo-3 and Bmovo-4 from the silkworm ovary and verified that ovarian development was regulated by the BmOVO proteins. Results: To understand the regulatory mechanisms of ovarian development, the regulation of four BmOVO isoforms on the B. mori ovarian tumor (Bmotu) promoter activity was investigated with luciferase reporter assays. The results showed the Bmotu promoter activity was positively regulated by BmOVO-1, BmOVO-2, BmOVO-3 and BmOVO-4 in a dose-dependent manner, of which BmOVO-2 had the highest transcriptional activation. However, the first (A1) and third acidic domains (A3) at the N-terminus of BmOVO-1 are transcriptional repression domains, while the fourth (A4) and fifth acidic domains (A5) are transcriptional activation domains. A recombinant BmOVO zinc-finger domain was found to bind to the GTACCGTTGTA sequence located at the Bmotu promoter. Furthermore, the Bmotu promoter activity was negatively regulated by ‘Tal-like’ peptide, which can trigger BmOVO-1 degradation at the N-terminus. Conclusions These results will help us to further understand the regulatory mechanisms of BmOVO isoforms on Bmotu promoter activity and ovarian development in the silkworm.

Abstract
Hippo signalling represents a cell proliferation and organ-size control pathway. Yorki (Yki), a component of the Hippo pathway, induces the transcription of a number of targets that promote cell proliferation and survival. The functions of Yki have been characterized in Drosophila and mammals, while there are few reports on silkworm, Bombyx mori. In the present study, we found that BmYki3 facilitates cell migration and cell division, and enlarges the cultured cell and wing disc size. Co-immunoprecipitation results indicated that BmYki3 may interact with thymosin, E3 ubiquitin-protein ligase, protein kinase ASK1, dedicator of cytokinesis protein 1, calcium-independent phospholipase A2 and beta-spectrin. RNA-seq results indicated that 4444 genes were upregulated and 10 291 genes were downregulated after BmYki3 was overexpressed in the cultured cells. GO annotation indicated that the up/downregulated genes were enriched in 268/382 GO terms (p < 0.01); KEGG analysis showed that the up/downregulated genes were enriched in 49/101 pathways. These findings provided novel information to understand the functions of BmYki3 in a cell proliferation and organ-size control pathway.

Abstract
Bombyx mori cypovirus (BmCPV) enters permissive cells via clathrin-mediated endocytosis pathway. However, the distinct entry mechanism for BmCPV is still ambiguous. The aim of this study is to investigate the role of gangliosides and cholesterol in BmCPV cell entry. The number of BmCPV virions attached to the cell surface and the expression level of BmCPV vp1 gene was significantly decreased by digestion of terminal sialic acids in gangliosides with neuraminidase (NA). Preincubation of different concentration of ganglioside GM1, GM2 or GM3 with BmCPV prior to infection, the reduction of BmCPV infectivity was found by GM2-treated in a dose-depend manner. BmCPV virions were found to colocalize with GM2 in the cell surface. The infectivity of BmCPV was reduced by anti-GM2 antibody treatment cells. Moreover, BmCPV infection was impaired by depletion of membrane cholesterol with MβCD, but the inhibitory effect of MβCD was restored by supplementing with cholesterol. The number of viral particles attached on the BmN cells was significantly decreased by pretreated with MβCD, and BmCPV infection was inhibited by silencing the expression of 3-hydroxy-3-methylglutaryl-CoA reductase gene (Hmg-r) in cholesterol biosynthesis pathway. These results indicate that ganglioside GM2 and cholesterol in membrane lipid rafts are essential for BmCPV attachment to cell surface for its cell entry.

Abstract
Bombyx mori cytoplasmic polyhedrosis virus (BmCPV) is a non-enveloped dsRNA virus, which specifically infect the midgut epithelium of B. mori. BmCPV enters permissive cells via clathrin-dependent endocytosis employing β1 integrin mediated internalization. Until now, the cell entry mechanism of BmCPV has not been known clearly. Here, we investigated whether tyrosine-protein kinase Src64B-like is involved in the cell entry of BmCPV. The Src64B-like gene was cloned and expressed in Escherichia coli (E. coli), and the recombinant protein Src64B-like was used to immunize mouse for preparation of anti-Src64B-like polyclonal antibody (pAb). After Src64B-like gene was silenced by RNAi, the infection of BmCPV was reduced by 59.48% ± 2.18% and 92.22% ± 1.12% in vitro and in vivo autonomously. Contrary to it, BmCPV infection could be enhanced by increasing the expression of Src64B-like. In addition, immunofluorescence assay showed that Src64B-like protein did not co-localize with BmCPV in the cultured BmN cells during viral infection. These results indicate that Src64B-like protein participates and plays an important role in the cell entry of BmCPV, but not contacting directly with BmCPV.

Abstract
Thus far, no systematic studies have examined circRNA expression profiles in the silkworm following B.mori nucleopolyhedrovirus (BmNPV) infection. To explore the expression patterns of circRNAs in the silkworm midgut following BmNPV infection, circRNAs in normal midguts and BmNPV-infected midguts were analyzed by high-throughput sequencing. A total of 353 circRNAs were significantly differentially expressed, of which 241 were upregulated and 112 were downregulated following infection. GO annotation and KEGG pathways analyses of these circRNAs showed that many key immunity pathways and metabolism pathways were enriched in the BmNPV-infected midguts. The potential roles of the predicted targets of the miRNAs that interacted with the circRNAs showed that ubiquitin, apoptosis, and endocytosis signaling pathways were enriched significantly by BmNPV infection.

Abstract
Objective: To explore the effect of chronic intermittent hypoxia (CIH) on rats hepatic function, and the protective mechanism of adiponectin (Ad). Methods: Sixty healthy male wistar rats were randomly divided into 4 groups: normal control (NC), NC+ Ad, CIH, and CIH+ Ad groups with 15 rats in each. The rats in CIH and CIH+ Ad groups were exposed to an intermittent hypoxic chamber 8 hours per day for 4 months. Meanwhile, the rats in both the NC and NC + Ad groups were housed with normal pressure air. The rats in the NC+ Ad and CIH+ Ad groups were additionally treated with an intravenous injection of Ad (10 μg), twice a week for 4 months. At the end of experiment, comparison among groups was made about plasma levels of aspartate amino transferase (AST), alanine amino transferase (ALT), degrees of endoplasmic reticulum stress (ERS) and mitochondrium associated cellular apoptosis. Results: No significant difference was detected in all items between NC and NC+ Ad groups (all P>0.05). Plasma hepatic enzyme levels of AST and ALT were significantly higher in CIH group [(319±21) and (113±9) U/L] than those in NC group [(178±19) and (51±9) U/L] and NC+ Ad group [(175±16) and (52±8) U/L] (all P<0.05). Compared NC with NC+ Ad group, there was more remarkable ERS and mitochondrial injury associated cellular apoptosis in hepatic tissues of CIH group. Such pathological changes were less obvious in CIH+ Ad group than in CIH group (all P<0.05). Conclusion: CIH can induce hepatic injury in rats, while Ad supplement may play a protective role possibly through inhibition of ERS and associated pathways of cellular apoptosis.

Abstract
Herein, tunable emissions in aggregation processes of triphenylamine derivatives (TPAQs) and their protonated cations, as well as protonated processes have been described. In this study, three triphenylamine-based compounds (TPAQs) were synthesized and their optical properties were investigated. Initially, the TPAQs displayed aggregation-induced emission enhancement (AIEE) properties via the restricted intramolecular charge transfer (ICT) state. Interestingly, the single-branched fluorophore (STPAQ) and its protonated cation emitted different color fluorescence in the solution and aggregation state. They emitted green fluorescence, which originated from the intramolecular charge transfer (ICT) state in a strong polar solvent, but the fluorescence bands turned blue, which was attributed to the LE state in the aggregated state. However, the cations of triple-branched fluorophores (TTPAQs) exhibited an inverse tunable emission process from bluish violet fluorescence of the LE state in a weak polar solvent (e.g., THF) to green fluorescence of the ICT state in the aggregated state. In a THF/water mixture solution (fw = 10%), the STPAQ could switch its emission between blue and green in the pH range of 10.0-0.5. This phenomenon enabled STPAQ to serve as a fluorescent pH sensor in solution. In the powder state, double-branched fluorophores (DTPAQs) could be used as a fluorescent sensor for the detection of acidic and basic organic vapors in the solid state.

Abstract
Three new chromophores incorporating acceptor-π-donor-π-acceptor structural motifs and mono-, di- and tri-branched diphenylsulfone base linked to triphenylamine through a hydrazone π-bridge were synthesized, and the photoluminescence properties of the three chromophores were studied in solutions as well as in aggregated states. All the fluorophores emitted strong blue fluorescence in THF. Mono- and di-branched triphenylamine both exhibited increasing blue fluorescence and displayed an AIEE effect in the aggregated state. Tri-branched triphenylamine emitted green fluorescence and presented the AIE effect in the aggregated state. These interesting phenomena have been interpreted by a molecular stacking mode with molecular dynamics (MD) and DFT calculations. The unique propeller shaped molecular configuration of triphenylamine prevented face to face π-π stacking and induced the hindered rotation, which resulted in the AIEE or AIE effect in the aggregated state. The enlarged coplanarity of diphenylhydrazone chains increased the conjugation of tri-branched triphenylamine, which was beneficial to the formation of ICT and AIE and resulted in emitting green ICT fluorescence in the aggregated state. Fluorescent microscope imaging and the fluorescent pictures of the powder states certified the strong AIEE effect or AIE effect in the solid.

Abstract
H9N2 is one of the major subtypes of influenza virus circulating in poultry in China, which has a wide host range from bird to mammals. Two H9N2 viruses were isolated from one mink farm in 2014. Phylogenetic analysis showed that internal genes of the H9N2 viruses have close relationship with those of H7N9 viruses. Interestingly, two H9N2 were separated in phylogenetic trees, indicating that they are introduced to this mink farm in two independent events. And further mice studies showed that one H9N2 caused obvious weight loss and 20% mortality in infected mice, while another virus did not cause any clinical sign in mice infected at the same dose. Genetic analysis indicated that the virulent H9N2 contain a natural mutation at 701N in PB2 protein, which was reported to contribute to mammalian adaptation. However, such substitution is absent in the H9N2 avirulent to mice. Circulation of H9N2 in mink may drive the virus to adapt mammals; continual surveillance of influenza virus in mink was warranted.

Abstract
The pathogenesis of Bombyx mori cytoplasmic polyhedrosis virus (BmCPV) infection is unclear, although accumulating evidence indicates that circular RNAs (circRNAs), which act as competing endogenous RNAs or positive regulators, play important roles in regulating gene expression in eukaryotes and, thus, may play a role in BmCPV infections. To explore the expression and biological functions of circRNAs in the silkworm midgut following BmCPV infection, silkworm circRNA expression profiles of normal midgut tissue (control) and BmCPV-infected midgut tissue (test) were determined using high-through sequencing. A total of 9,753 and 7,475circRNAs were detected from the control and test samples, respectively. The two samples shared 6,085 circRNAs, while 646 and 737 circRNAs were expressed specifically in the control and test samples, respectively. A total of 3,638 circRNAs were shown to be differentially expressed, and 400 circRNAs were substantially differentially expressed with a fold-change ≥ 2.0 (p< 0.05 and a false discover rate < 0.05), of which 294 were up-regulated and 106 were down-regulated following infection. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were conducted to determine the principal functions of the substantially differentially regulated genes. circRNA-miRNA interaction networks were constructed based on a correlation analysis between the differentially expressed circRNAs and the nature of their microRNA (miRNA) binding sites. The network inferred that 13 miRNAs interacting with 193 circRNAs were among the 300 most abundant relationships. bmo-miR-3389-5p, bmo-miR-745-3p, and bmo-miR-3262 were related to 30, 34, and 34 circRNAs, respectively. circRNA_8115, circRNA_9444, circRNA_4553, circRNA_0827, and circRNA_6649 contained six, five, four, four, and four miRNA binding sites, respectively. We further found that alternative circularization of circRNAs is a common feature in silkworms and that the junction sites of many silkworm circRNAs are flanked by canonical GT/AG splicing signals. Our study is the first to show the circRNA response to virus infection. Thus, it provides a novel perspective on circRNA-miRNA interactions during BmCPV pathogenesis, and it lays the foundation for future research of the potential roles of circRNAs in BmCPV pathogenesis.

Abstract
The genome of Bombyx mori cytoplasmic polyhedrosis virus (BmCPV) contains 10 double stranded RNA segments (S1-S10). The segment 7 (S7) encodes 50kDa protein which is considered as a structural protein. The expression pattern and function of p50 in the virus life cycle are still unclear. In this study, the viral structural protein 7 (VP7) polyclonal antibody was prepared with immunized mouse to explore the presence of small VP7 gene-encoded proteins in Bombyx mori cytoplasmic polyhedrosis virus. The expression pattern of vp7 gene was investigated by its overexpression in BmN cells. In addition to VP7, supplementary band was identified with western blotting technique. The virion, BmCPV infected cells and midguts were also examined using western blotting technique. 4, 2 and 5 bands were detected in the corresponding samples, respectively. The replication of BmCPV genome in the cultured cells and midgut of silkworm was decreased by reducing the expression level of vp7 gene using RNA interference. In immunoprecipitation experiments, using a polyclonal antiserum directed against the VP7, one additional shorter band in BmCPV infected midguts was detected, and then the band was analyzed with mass spectrum (MS), the MS results showed thatone candidate interacted protein (VP7 voltage-dependent anion-selective channel-like isoform, VDAC) was identified from silkworm. We concluded that the novel viral product was generated with a leaky scanning mechanism and the VDAC may be an interacted protein with VP7.

Abstract
Autophagy is essential for maintaining glucose homeostasis, but the mechanism by which energy deprivation activates autophagy is not fully understood. We show that Mec1/ATR, a member of the DNA damage response pathway, is essential for glucose starvation-induced autophagy. Mec1, Atg13, Atg1, and the energy-sensing kinase Snf1 are recruited to mitochondria shortly after glucose starvation. Mec1 is recruited through the adaptor protein Ggc1. Snf1 phosphorylates Mec1 on the mitochondrial surface, leading to recruitment of Atg1 to mitochondria. Furthermore, the Snf1-mediated Mec1 phosphorylation and mitochondrial recruitment of Atg1 are essential for maintaining mitochondrial respiration during glucose starvation, and active mitochondrial respiration is required for energy deprivation-activated autophagy. Thus, formation of a Snf1-Mec1-Atg1 module on mitochondria governs energy deprivation-induced autophagy by regulating mitochondrial respiration.

Abstract
Receptor-mediated endocytosis using a β1 integrin-dependent internalization was considered as the primary mechanism for the initiation of mammalian reovirus infection. Bombyx mori cypovirus (BmCPV) is a member of Reoviridae family which mainly infects the midgut epithelium of silkworm; the cell entry of BmCPV is poorly explored. In this study, co-immunoprecipitation (Co-IP), virus overlay protein binding assay (VOPBA), and BmCPV-protein interaction on the polyvinylidene difluoride membrane (BmCPV-PI-PVDF) methods were employed to screen the interacting proteins of BmCPV, and several proteins including integrin beta and receptor for activated protein kinase C (RACK1) were identified as the candidate interacting proteins for establishing the infection of BmCPV. The infectivity of BmCPV was investigated in vivo and in vitro by RNA interference (RNAi) and antibody blocking methods, and the results showed that the infectivity of BmCPV was significantly reduced by either small interfering RNA-mediated silencing of integrin beta and RACK1 or antibody blocking of integrin beta and RACK1. The expression level of integrin beta or RACK1 is not the highest in the silkworm midgut which is a principal target tissue of BmCPV, suggesting that the molecules other than integrin beta or RACK1 might play a key role in determining the tissue tropism of BmCPV infection. The establishment of BmCPV infection depends on other factors, and these factors interacted with integrin beta and RACK1 to form receptor complex for the cell entry of BmCPV.

Abstract
UNLABELLED Patients with spinal cord deficits following new unstable osteoporotic compression fracture and surgical contraindications were considered to receive conservative treatment. Teriparatide was better than alendronate at improving bone mineral density and bone turnover parameters, as well as preventing aggravation of spinal cord compromise. INTRODUCTION This study compared the preventive effects of teriparatide and alendronate on aggravation of spinal cord compromise following new unstable osteoporotic vertebral compression fracture (OVCF) in patients with surgical contraindications. METHODS This was a 12-month, randomized, open-label study of teriparatide versus alendronate in 49 patients with new unstable OVCF and surgical contraindications. Neurological function was evaluated using modified Japanese Orthopedic Association (mJOA) score (11-point scale, the maximum score of 11 implies normalcy). Visual analog scale (VAS) scores, kyphotic angles, anterior-border heights and diameters of the spinal canal of the fractured vertebrae, any incident of new OVCFs (onset of OVCF during follow-up), spine bone mineral density (BMD), and serum markers of bone resorption and bone formation were also examined at baseline and 1, 3, 6, and 12 months after initiation of the medication regimen. RESULTS At 12 months, mean mJOA score had improved in the teriparatide group and decreased in the alendronate group. Mean concentrations of bone formation and bone resorption biomarkers, mean spine BMD, and mean anterior-border height and spinal canal diameter of the fractured vertebrae were significantly greater in the teriparatide group than in the alendronate group. Mean VAS score, mean kyphotic angle of the fractured vertebrae, and incidence of new OVCFs were significantly smaller in the teriparatide group than in the alendronate group. CONCLUSIONS In patients with neurological deficits following new unstable OVCF and with surgical contraindications, teriparatide was better than alendronate at improving the BMD and the bone turnover parameters, as well as preventing aggravation of spinal cord compromise.

Abstract
Transforming growth factor (TGF)-β superfamily members inhibit Bombyx mori nucleohedrovirus (BmNPV) multiplication in silkworm are not determined. In this study, we first found that BmNPV RNA transcription and protein expression level were regulated by TGF-β members, Decapentaplegic (Bmdpp) and Dawdle (Bmdaw) in the domesticated silkworm, B. mori and silkworm ovary-derived cells. Furthermore, subcellular localization showed that Bmdpp and Bmdaw were mainly presented in cytomembrane of the cultured BmN cells. Tissues expression pattern analysis found that the highest expression levels of Bmdpp and Bmdaw genes were in the hemocyte of fifth instar larvae. During the immune response, the expression level of Bmdpp gene was elevated and Bmdaw gene was declined in BmNPV infected BmN cells and silkworm. The multiplication of BmNPV was inhibited by overexpression of Bmdpp and Bmdaw genes in BmN cells. RNA interference experiments found that the multiplication of BmNPV was raised with specific siRNAs of Bmdpp and Bmdaw genes in BmN cells. The antiviral immune pathways were not significantly regulated by the TGF-β superfamily members. Taken together, these findings provided a clue to understand the function of Bmdpp and Bmdaw gene in response to the BmNPV infection in silkworm.
