Resveratrol promotes mammary cell proliferation and antioxidation capacity during pregnancy and lactation in mice. J Appl Microbiol 2020; 130:450-463. [PMID: 32544275 DOI: 10.1111/jam.14747] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Revised: 06/05/2020] [Accepted: 06/09/2020] [Indexed: 12/19/2022]
Abstract
AIMS Reproduction can induce maternal oxidative stress, and resveratrol is able to alleviate oxidative stress. This study aimed to investigate the protective effects of resveratrol supplementation in mice during pregnancy and lactation. METHODS AND RESULTS Pregnant mice were randomly divided into three groups: (i) Pure water (Con); (ii) Cellulose sodium dissolves with 20 mg kg-1 resveratrol (R1) and (iii) Cellulose sodium dissolves with 40 mg kg-1 resveratrol (R2). The experiment starts at pregnancy and ends at weaning. The results showed that resveratrol increased mammary cell proliferation and the mRNA expressions of UDP glucuronosyltransferase family 1 member A1 (UGT1A1) and cytochrome P450 proteins (CYP1A1), while decreased superoxide dismutase, extracellular (SOD3) in the mammary gland. Further study showed that resveratrol promoted the mRNA expressions of genes involved in mitophagy, such as transcription factor Eβ (Tfeβ), Bcl1lc3β, homosapiens microtubule-associated protein 1 light-chain 3 beta (Map1lc3β), Parkin, sequestosome1 (p62), autophagy-related protein (Atg5) and Beclin-1 (Becn1) in the mammary gland. Moreover, resveratrol increased the abundances of some intestinal microbial species. 40 mg kg-1 resveratrol significantly increased the contents of Acidobacteri, unidentified acidbacteria, Bacilales, Staphylococcaceae and Staphylococcus at phylum, class, order, family and genus level respectively. CONCLUSION Our results indicate that resveratrol supplementation may promote mammary cell proliferation and antioxidant ability through mitophagy and regulating gut microbiota in pregnant mice. SIGNIFICANCE AND IMPACT OF THE STUDY Current study proved that resveratrol could affect mammary cell proliferation and antioxidation capacity during pregnancy and lactation in mice for the first time. The underlying mechanisms may be related to mitophagy and gut microbiota.

MicroRNA-23c inhibits articular cartilage damage recovery by regulating MSCs differentiation to chondrocytes via reducing FGF2. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2020; 23:941-948.

Abstract
OBJECTIVE The aim of the study was to explore the role of microRNA-23c in the differentiation of marrow stromal cells (MSCs) to chondrocytes and its potential mechanism. MATERIALS AND METHODS MSCs were first isolated from rat bone marrow for cell culture. Surface antigens of MSCs (CD29 and CD34) were identified by flow cytometry. MSCs were induced for chondrogenic differentiation in MCDM (Mesenchymal Stem Cell Chondrogenic Differentiation Medium) for 0, 3, and 7 days, respectively, followed by detection of RUNX2, microRNA-23c and FGF2 expressions by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Alcian blue staining was performed to access proteoglycan deposition in MSCs transfected with microRNA-23c mimics or inhibitor. Western blot was conducted to detect the protein expressions of ACAN and COL2A1 in MSCs. The binding condition between microRNA-23c and FGF2 was verified by dual-luciferase reporter gene assay. Finally, MSCs were co-transfected with microRNA-23c mimics and FGF2 overexpression plasmid for rescue experiments. RESULTS On the fourth day of MSCs isolation, MSCs were in an elongated shape. Flow cytometry results showed positive expression of CD29 and negative expression of CD34, which were consistent with MSCs phenotype. QRT-PCR data elucidated that the mRNA levels of RUNX2 and FGF2 gradually increased, whereas microRNA-23c expression decreased with the prolongation of chondrogenic differentiation. Transfection of microRNA-23c mimics in MSCs remarkably elevated microRNA-23c expression. Alcian blue staining showed that microRNA-23c overexpression results in less proteoglycan deposition in MSCs than that of controls. Both mRNA and protein expressions of ACAN and COL2A1 decreased after microRNA-23c overexpression. Dual-luciferase reporter gene assay confirmed that FGF2 binds to microRNA-23c. Further Western blot results demonstrated that FGF2 expression is negatively regulated by microRNA-23c. FGF2 overexpression reversed the inhibitory effects of microRNA-23c on proteoglycan deposition, as well as expressions of ACAN and COL2A1. CONCLUSIONS MicroRNA-23c expression decreases during chondrogenic differentiation of MSCs, which inhibits MSCs differentiation to chondrocytes by inhibiting FGF2.

Abstract
The Drosophila melanogaster cell line 1182-4, which constitutively lacks centrioles, was established many years ago from haploid embryos laid by females homozygous for the maternal haploid (mh) mutation. This was the first clear example of animal cells regularly dividing in the absence of this organelle. However, the cause of the acentriolar nature of the 1182-4 cell line remained unclear and could not be clearly assigned to a particular genetic event. Here, we detail historically the longstanding mystery of the lack of centrioles in this Drosophila cell line. Recent advances, such as the characterization of the mh gene and the genomic analysis of 1182-4 cells, allow now a better understanding of the physiology of these cells. By combining these new data, we propose three reasonable hypotheses of the genesis of this remarkable phenotype.

Abstract
Objective: To study the early dynamics of the epidemic of coronavirus disease (COVID-19) in China from 15 to 31 January, 2020, and estimate the corresponding epidemiological parameters (incubation period, generation interval and basic reproduction number) of the epidemic. Methods: By means of Weibull, Gamma and Lognormal distributions methods, we estimated the probability distribution of the incubation period and generation interval data obtained from the reported COVID-19 cases. Moreover, the AIC criterion was used to determine the optimal distribution. Considering the epidemic is ongoing, the exponential growth model was used to fit the incidence data of COVID-19 from 10 to 31 January, 2020, and exponential growth method, maximum likelihood method and SEIR model were used to estimate the basic reproduction number. Results: Early COVID-19 cases kept an increase in exponential growth manner before 26 January, 2020, then the increase trend became slower. The average incubation period was 5.01 (95%CI: 4.31-5.69) days; the average generation interval was 6.03 (95%CI: 5.20-6.91) days. The basic reproduction number was estimated to be 3.74 (95%CI: 3.63-3.87), 3.16 (95%CI: 2.90-3.43), and 3.91 (95%CI: 3.71-4.11) by three methods, respectively. Conclusions: The Gamma distribution fits both the generation interval and incubation period best, and the mean value of generation interval is 1.02 day longer than that of incubation period. The relatively high basic reproduction number indicates that the epidemic is still serious; Based on our analysis, the turning point of the epidemic would be seen on 26 January, the growth rate would be lower afterwards.

Abstract
Osteopontin (OPN) is a multifunctional extracellular matrix phosphoprotein that has a specific and complicated structure, and contributes to numerous physiological and pathological activities. The mechanism of OPN in many diseases has been confirmed; however, the role of OPN in myasthenia gravis (MG) remains unclear. In this study, we recombined rat OPN protein in vitro, and assessed how OPN affects the development of autoimmunity using an experimental autoimmune myasthenia gravis (EAMG) rat model. The results showed that the concentration of OPN in serum was up-regulated. Both mRNA and protein levels in splenocytes increased in the EAMG model. OPN treatment in vitro strongly promoted the differentiation of Th1 cells, and inhibited the differentiation of Treg cells. Intraperitoneal injection of OPN revealed the early incidence of EAMG, and more serious disease. This effect was accompanied by an increased percentage of Th1 cells. In conclusion, OPN likely exacerbates the pathogenesis of EAMG by promoting the differentiation of Th1 cells and inhibiting the differentiation of Treg cells.

Abstract
Non-centrosomal microtubule-organizing centres (ncMTOCs) have a variety of roles presumed to serve the diverse functions of the range of cell types in which they are found. ncMTOCs are diverse in their composition, subcellular localization, and function. Here we report a perinuclear MTOC in Drosophila fat body cells that is anchored by Msp300/Nesprin at the cytoplasmic surface of the nucleus. Msp300 recruits the MT minus-end protein Patronin/CAMSAP, which functions redundantly with Ninein to further recruit the MT polymerase Msps/XMAP215 to assemble non-centrosomal MTs and does so independently of the widespread MT nucleation factor γ-tubulin. Functionally, the fat body ncMTOC and the radial MT arrays it organizes is essential for nuclear positioning and for secretion of basement membrane components via retrograde dynein-dependent endosomal trafficking that restricts plasma membrane growth. Together, this study identifies a perinuclear ncMTOC with unique architecture and MT regulation properties that serves vital functions.

Abstract
Acetylcholine (ACh) is best known as a neurotransmitter and was the first such molecule identified. ACh signalling in the neuronal cholinergic system has long been known to regulate numerous biological processes (reviewed by Beckmann and Lips). In actuality, ACh is a ubiquitous signalling molecule that is produced by numerous non-neuronal cell types and even by some single-celled organisms. Within multicellular organisms, a non-neuronal cholinergic system that includes the immune system functions in parallel with the neuronal cholinergic system. Several immune cell types both respond to ACh signals and can directly produce ACh. Recent work from our laboratory has demonstrated that the capacity to produce ACh is an intrinsic property of T cells responding to viral infection, and that this ability to produce ACh is dependent upon IL-21 signalling to the T cells. Furthermore, during infection this immune-derived ACh is necessary for the T cells to migrate into infected tissues. In this review, we will discuss the various sources of ACh that are relevant during immune responses and describe how ACh acts on immune cells to influence their functions. We will also address the clinical implications of this fascinating aspect of immunity, focusing on ACh's role in the migration of T cells during infection and cancer.

Abstract
Abstract
Introduction
Chronic right cervical vagal nerve electric stimulation (VS) exerted prognostic benefits in heart failure rats. Exploring the mechanism is significant for clinical application. This study examined the effect of VS on arginine vasopressin (AVP) secretion and drinking behavior in the rats with chronic heart failure.
Methods
After a week recovery of myocardial infarction (MI), surviving rats after were randomly instrumented to VS group and sham stimulation (SS) group. A drop sensor was used to record real-time fluid consumption. Blood samples were collected weekly from the 3rd week during the 6 weeks treatment.
Results
Vagal stimulation did not change the daily fluid consumption (Mean ± SE, 76.2 ± 1.1 vs. 77.8 ± 2.1 ml/kg/day, n = 6, P < 0.05). Thirst, which is defined as per drinking volume (PDV), significantly increased during the early weeks after MI (Fig A), while VS significantly suppressed PDV (Fig B is the data of 6th week) by increasing the drinking intervals. The level of plasma AVP was increased to about 2 fold during 6 weeks observation in the SS group, however, VS suppressed this upregulation (Fig C).
Conclusion
These results suggest that VS may activate vagal afferent components which related to inhibition of AVP secretion and then suppressed the augmentation of thirst. Frequent drinking small volume may benefit for homeostasis in CHF.

Abstract
AIMS Leucine supplementation promotes intestinal health, but the mechanism is largely unknown. This study aimed to elucidate the mechanisms underlying the beneficial effects of leucine on intestinal homeostasis. METHODS AND RESULTS Female ICR mice (6-week-old) were randomly assigned into three groups: (i) mice received a basal diet; (ii) mice received a dietary 0·5% crystalline l-leucine supplementation; and (iii) mice received a dietary 1·0% crystalline l-leucine supplementation. Our results showed that leucine supplementation stimulated the secretion of SIgA in mice ileum and expression of cytokines related to SIgA production. Moreover, leucine supplementation improved the expression of mTOR and p70S6K1 expression. Further study showed that leucine supplementation markedly decreased microbiota richness and induced a shift in the Firmicutes : Bacteroidetes ratio in favour of Firmicutes. CONCLUSIONS Therefore, our data suggested that leucine supplementation could enhance intestinal health through the regulation of mTOR pathway and promoting SIgA secretion in the mouse intestine, which might be associated with intestinal microbiota. SIGNIFICANCE AND IMPACT OF THE STUDY The present study found that dietary leucine supplementation of mice could improve intestinal health by enhancing intestinal SIgA secretion via a nonexclusive mechanism, which might include T cell-dependent pathway, T cell-independent pathway and gut microbiota.

Abstract
Abstract
Introduction
Parasympathetic activation by donepezil has been shown to improve prognosis in chronic heart failure (CHF) rats following myocardial infarction. We examined whether donepezil is effective in the treatment of another CHF model complicated with renal artery stenosis (RAS)-induced hypertension.
Methods
RAS was created by ligating the left renal artery up to 50% in SD rats, at the same time, we implanted a blood pressure (BP) transmitter for confirming RAS-induced hypertension (7-week post-RAS: systolic BP = 154±7 mmHg; diastolic BP = 115±8 mmHg). At the 11th week after induction of RAS, surviving animals were randomly assigned to untreated (UT, n=10) or donepezil treated [DT, n=10, dissolved in drinking water (3mg/kg/day)] group. After a 6-week treatment, the effects of donepezil were evaluated by hemodynamics, blood levels of neurohumoral markers, and morphology.
Results
Compared with UT, DT significantly prevented the progression of the left kidney atrophy (2.38±0.13 vs. 1.51±0.34 g/kg, P<0.05). DT also significantly improved cardiac remodeling, through suppressing the progression of cardiac hypertrophy (2.30±0.06 vs. 2.57±0.08 g/kg, P<0.01), cardiac dysfunction [cardiac index: 102±3 vs. 86±3ml/min/kg, P<0.05; left ventricular (LV) end-diastolic pressure: 12±2 vs. 20±2 mmHg, P<0.05; LV dp/dtmin: 5856±259 vs. 4924±227 mmHg/sec, P<0.05]. DT not only decreased serum levels of creatinine (0.54±0.02 vs. 0.63±0.03 mg/dl, P<0.05) and uric acid (1.4±0.2 vs. 1.9±0.2 mg/dl, P<0.05); but also decreased plasma levels of norepinephrine (273±38 vs. 846±242, P<0.01), angiotensin II (17±2 vs. 23±2 pg/ml, P<0.05), AVP (2729±347 vs. 4783±695 pg/ml, P<0.05) and BNP (360±13 vs. 460±39 pg/ml, P<0.05), and suppressed the systemic inflammation (CRP: 190±12 vs. 382±58 mg/ml, P<0.01).
Conclusions
Donepezil treatment markedly prevented the progression of cardiac remodeling and renal dysfunction, and improved the neurohumoral markers in the CHF rat model complicated with RAS-induced hypertension, suggesting that donepezil may be used as a new pharmacotherapy for CHF patients complicated with RAS-induced hypertension.

Abstract
Abstract
Background
Septic shock is associated with sympathetic over-activation characterized by tachycardia, which is associated with poor survival. Though several kinds of drugs are available to reduce heart rate (HR), it is not clear which drug should be used to reduce HR effectively in initial hemodynamic resuscitation in septic shock.
Purpose
The aim of this study was to experimentally investigate comparative effects of landiolol (a β-blocker) and ivabradine (an If-channel inhibitor) on initial hemodynamic resuscitation in a canine model of endotoxin shock.
Methods
We used 19 anesthetized dogs. Seven dogs were allocated to control (CT) group, six dogs to landiolol (BB) group, and six dogs to ivabradine (IVA) group. In all the groups, endotoxin shock was induced by intravenous infusion of Escherichia coli lipopolysaccharide (4 mg/kg) over 1 h. After induction of endotoxin shock, we started hemodynamic resuscitation to restore mean arterial pressure (AP) and cardiac output (CO) by infusing noradrenaline (NA) and Ringer acetate solution (RiA). Dose of NA and RiA were automatically titrated with use of a computer-controlled drug infusion system that we developed previously. Hemodynamic resuscitation was continued for 4 h. During resuscitation, the BB group was given landiolol infusion at a low-dose range (1–10 μg/kg/min, manually titrated), while the IVA group was given ivabradine at 0.25 mg/kg bolus-injected every 2 h.
Results
The drug infusion system automatically restored AP to 70 mmHg and CO to greater than 90% of baseline level in all the groups. The restored AP and CO were not significantly different among the three groups (Figure A, B). There were no significant differences in the computer-controlled infusion rate of NA and cumulated volume of RiA infused among the three groups (Figure C). During the first 2 h of resuscitation, HR was significantly reduced in the BB and IVA groups in comparison to the CT group (Figure D). However, only in the BB group, cardiac oxygen consumption was significantly lower than that in the CT group (Figure E). Blood lactate level decreased significantly after hemodynamic resuscitation only within the BB group (Figure F).
Figure 1
Conclusions
In the initial hemodynamic resuscitation of septic shock, both low-dose landiolol infusion and ivabradine injection may be used to reduce HR. However, to optimize cardiac energetics and peripheral microhemodynamics, low-dose landiolol infusion may be preferable to ivabradine injection.

Abstract
OBJECTIVE To examine trends and variations in billed and paid amounts for preventive dental procedures by race/ethnicity, age, and sex in Wisconsin dental Medicaid. METHODS We analyzed data from the 2001 to 2013 Wisconsin Medicaid claims database for preventive dental procedures for children and adults. Billed and paid amounts for preventive dental procedures were aggregated over a visit and adjusted for inflation based on the Medical Care Consumer Price Index produced by the Bureau of Labor Statistics for 2013. Quantile regression was used to examine the trends over time and the effect of patient demographics. RESULT At the 50th and 75th percentiles, the overall billed amounts for preventive dental procedures were $84.97 and $105.53, and the paid amounts were $35.80 and $41.66, respectively. At the 75th percentile, there was a $2.24 increase per year in the billed amount and a $26.88 overall increase from 2001 to 2013. In the paid amount, there was a $1.34 decrease per year for an overall $16.07 decrease from 2001 to 2013. Billed and paid claims for racial/ethnic minority enrollees were $1 to $3 higher per visit at the 75th percentile when compared with those of Whites. Regarding the billed:paid ratio, White, African American, and Hispanic enrollees had values of 50% to 52%, whereas American Indians had the lowest value at 47.7%. At the 75th percentile, children aged 10 to 19 y had significantly higher billed ($26.73) and paid ($9.92) amounts than did adults aged 20 to 69 y. CONCLUSION The billed amount increased over time, and the paid amount decreased after adjustment for inflation. In addition, there was a wide gap between billed and paid amounts over time. KNOWLEDGE TRANSFER STATEMENT This study highlights clear differences between paid and billed amounts in Wisconsin dental Medicaid. The financial health of dental practices is dependent on appropriate reimbursement for dental services provided; thus, information of this nature could serve as a proxy performance measure for access to preventive dental care. Findings from this study could be used by policy makers and dental Medicaid program managers to develop outcome metrics to improve access to preventive dental services.

Abstract
OBJECTIVE Mission of Mercy (MoM) events are scheduled to provide care to populations suffering from urgent needs and inadequate access to dental care in the United States. This study examined individual and county-level characteristics of MoM attendees and the factors associated with changes in the rate of attendance. METHODS Deidentified archival data for MoM events available from the America's Dentists Care Foundation (2013-2016) were analyzed. Summary statistics were calculated separately for each year. Chi-square test was performed to identify changes in attendance distribution over time. Poisson regression analyses were conducted to test changes in the rate of attendance with and without adjustment for county-level characteristics and history of prior MoM events. RESULTS Total numbers of attendees at Wisconsin MoM events were 1,560, 1,635, 1,187, and 951 in 2013, 2014, 2015, and 2016, respectively. Attendees were mostly female (>50%) and White (58%-81%), and mean age ranged between 36.5 and 39.2 y. The average travel distance ranged between 27 and 80 miles. Residents of counties where MoM events were held in previous years were more likely to attend another MoM event after adjusting for county distance to current location. After adjusting for dentists-to-population ratio, event history, and county distance to event location, we found that there was no statistically significant change in the rate of attendance from 2013 to 2016. CONCLUSIONS Previous attendees with experience of attending a MoM event in their counties of residence were more likely to attend another MoM event. Higher rates of attendance were associated with shorter travel distances to MoM events. KNOWLEDGE TRANSFER STATEMENT The Mission of Mercy (MoM) events are promoted by local dental organizations to highlight the issue of access to dental care and bring greater awareness to the problem by providing urgent dental care to populations in need. Through the data-sharing practices and analyses, policy makers, dental health advocates, and program organizers will have a better understanding of the impact and reach of the program. Findings from this study will help to expand program practices, promote efficiency, and aid in the identification of appropriate event locations, innovative strategies, and public policies relevant to addressing access to dental care.

Chronic inflammation of the salivary glands from pathologic conditions such as Sjögren's syndrome can result in glandular destruction and hyposalivation. To understand which molecular factors may play a role in clinical cases of salivary gland hypofunction, we developed an aquaporin 5 (AQP5) Cre mouse line to produce genetic recombination predominantly within the acinar cells of the glands. We then bred these mice with the TNF-αglo transgenic line to develop a mouse model with salivary gland-specific overexpression of TNF-α; which replicates conditions seen in sialadenitis, an inflammation of the salivary glands resulting from infection or autoimmune disorders such as Sjögren's syndrome. The resulting AQP5-Cre/TNF-αglo mice display severe inflammation in the salivary glands with acinar cell atrophy, fibrosis, and dilation of the ducts. AQP5 expression was reduced in the salivary glands, while tight junction integrity appeared to be disrupted. The immune dysregulation in the salivary gland of these mice led to hyposalivation and masticatory dysfunction.

Enhancement of fluorescence emission difference microscopy using conjugated vortex phase modulation. J Microsc 2018; 272:151-159.

Abstract
In this paper, we propose and demonstrate an improved fluorescence emission difference microscopy (FED) method, exploiting programmable phase modulation for image enhancement. The main novelty of the proposed approach lies in the matched size and intensity of two excitation spots. The proposed method improves the FED performance on image quality via artefact elimination. We demonstrate the feasibility of this method through theoretical studies and experimental tests. The experimental results of nanobeads and cells validate the practical performance of this method, which can enable reliable observations at superresolution in biomedical studies. LAY DESCRIPTION: In this paper, we propose a method to improve the imaging quality of regular fluorescence emission difference (FED) microscopy. In regular FED imaging, a solid and a doughnut excitation beam are successively used to acquire two images which are then subtracted with each other to improve the resolution of confocal microscopy. The doughnut beam can be generated by modulating the excitation beam with a vortex phase mask. Note that both of the excitation beam and the vortex phase mask must have the same handed direction in regular FED microscopy. However, some negative values may be produced and some information may be lost due to the subtraction process in regular FED imaging, which is mainly caused by the mismatched size and intensity of these two excitation spots. To address this issue, we propose conjugated FED (cFED) microscopy which additionally uses a conjugated vortex phase mask to modulate the solid beam to extend its focal spot size to be matched with the doughnut spot, which means the handed direction of the solid beam and the vortex phase mask is different. Besides, in order not to damage the resolution, the doughnut beam needs to be saturated to some degree. The experiment results show that, at the same resolution level, the negative values and the information loss in cFED image are all less than that of regular FED image.

Abstract
BACKGROUND Our previous study suggested that mitochondrial haplogroup F (mtDNA F) was a longevity-associated biomarker, but the effect of mitochondrial haplogroup F on longevity individuals with metabolic syndrome (MetS) was not clear. Thus we explored the association between mtDNA F and MetS among longevity and control population in Guangxi Zhuang Autonomous Region, China. METHOD A total of 793 individuals consisting of 307 long-lived participants and 486 local healthy controls were involved in this study. Genotypes of mtDNA F were amplified by polymerase chain reaction and Sanger sequenced. MetS was defined according to the revised National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATPIII ) criteria. RESULTS The prevalence of MetS in longevity group (28.0%) was higher than that (18.5%) in control group (P=0.002). Through the case-control stratify analysis, the prevalence of MetS in mtDNA F+ longevity individuals (29.8%) was 4.6 fold higher than that (5.3%) in local control group (P<0.001). However, after further longevity-only analysis, no association between MetS and mtDNA F+ in longevity group was observed (P=0.167). Following same analysis of two variables in control group, we found that the prevalence of MetS in mtDNA F- (95.8%) was higher than that in mtDNA F+ (5.3%); conversely, the prevalence of non-metabolic syndrome (NMetS) in mtDNA F+ (94.7%) was markedly higher than that in mtDNA F- (4.2%) (P<0.001). CONCLUSION We demonstrated that mtDNA F+ , as a molecuar biomarker, might not only confer beneficial effect to resistance against MetS but also function as a positive factor for long-life span among the population in Guangxi Zhuang Autonomous Region, China.

Abstract
Foot-and-mouth disease virus (FMDV) has a dual capacity to induce either acute or persistent infection in host animals. Establishment of an in vitro cell model of FMDV persistent infection facilitates the study of the mechanism underlying this type of infection. In this study, we analyzed gene expression profiles of both acute and persistent infections using cross-species microarrays. Our data suggest that human microarrays are more efficient than mouse microarrays in hybridization with cDNA from BHK-21 cells although the mouse is closer to the Syrian hamster in taxonomy. A set of differentially expressed genes (DEGs) that may be involved in the determination of acute or persistent infection was identified by using human or mouse microarrays. Seven common DEGs were found in both human and mouse arrays and showed similar fold changes. Among the DEGs, 33 genes were selected for further validation by using qRT-PCR and presented consistent results. The analysis of Gene Ontology Biological Processes indicated that various biosynthetic and metabolic processes were negatively regulated in the group of acute infection whereas multicellular organismal development processes were positively regulated in the group of persistent infection. Our study demonstrates the plausibility and utility of using cross-species microarrays to study FMDV-infected mammalian cells. The combined use of two types of microarrays can be more informative in exploring the mechanisms underlying the infections of FMDV.

Abstract
Acetyl-coenzyme A carboxylase (ACC) catalyses the carboxylation of acetyl-coenzyme A (acetyl-CoA) to produce malonyl-CoA during the de novo synthesis of fatty acids. Spirotetramat, an inhibitor of ACC, is widely used to control a range of sucking insects, including the Aphis gossypii. In the present study, Reverse transcription quantitative real-time PCR (RT-qPCR) results demonstrated that ACC was significantly overexpressed in a laboratory-selected spirotetramat-resistant strain compared with the susceptible strain. ACC RNA interference significantly suppressed fecundity and led to cuticle formation deficiencies in resistant adults and nymphs compared with the control. The full-length ACC gene was sequenced from both resistant and susceptible cotton aphids, and a strong association was found between spirotetramat resistance and 14 amino acid substitutions in the biotin carboxylase domain and carboxyl transferase domain of the ACC gene. Furthermore, ACC activity was higher in resistant aphids than in the susceptible strain, and ACC in the resistant aphids exhibited significant insensitivity to spirotetramat and spirotetramat-enol. The results indicate that the overexpressed insensitive (mutated) ACC target played an important role in the high levels of spirotetramat resistance observed here. This association of amino acid substitution with resistance is the first report of a potential target site mechanism affecting spirotetramat in the cotton aphid.
