Abstract
Prior studies on transcriptomes of hypothalamus and ovary revealed that AKT3 is one of the candidate genes that might affect egg production in White Muscovy ducks. The role of AKT3 in the uterus during reproductive processes cannot be overemphasized. However, functional role of this gene in the tissues and on egg production traits of Muscovy ducks remains unknown. To identify the relationship between AKT3 and egg production traits in ducks, relative expression profile was first examined prior to identifying the variants within AKT3 that may underscore egg production traits [age at first egg (AFE), number of eggs at 300 d (N300D), and number of eggs at 59 wk (N59W)] in 549 ducks. The mRNA expression of AKT3 gene in high producing (HP) ducks was significantly higher than low producing (LP) ducks in the ovary, oviduct, and hypothalamus (P < 0.05 or 0.001). Three variants in AKT3 (C-3631A, C-3766T, and C-3953T) and high linkage block between C-3766T and C-3953T which are significantly (P < 0.05) associated with N300D and N59W were discovered. This study elucidates novel knowledge on the molecular mechanism of AKT3 that might be regulating egg production traits in Muscovy ducks.

Abstract
Skeletal muscle is the largest metabolic organ in the body, and its metabolic flexibility is essential for maintaining systemic energy homeostasis. Metabolic inflexibility in muscles is a dominant cause of various metabolic disorders, impeding muscle development. In our previous study, we found lncRNA ZFP36L2-AS (for “ZFP36L2-antisense transcript”) is specifically enriched in skeletal muscle. Here, we report that ZFP36L2-AS is upregulated during myogenic differentiation, and highly expressed in breast and leg muscle. In vitro, ZFP36L2-AS inhibits myoblast proliferation but promotes myoblast differentiation. In vivo, ZFP36L2-AS facilitates intramuscular fat deposition, as well as activates fast-twitch muscle phenotype and induces muscle atrophy. Mechanistically, ZFP36L2-AS interacts with acetyl-CoA carboxylase alpha (ACACA) and pyruvate carboxylase (PC) to induce ACACA dephosphorylation and damaged PC protein stability, thus modulating muscle metabolism. Meanwhile, ZFP36L2-AS can activate ACACA to reduce acetyl-CoA content, which enhances the inhibition of PC activity. Our findings present a novel model about the regulation of lncRNA on muscle metabolism.

Abstract
Obesity is a global epidemic health disorder and associated with several diseases. Body weight-reducing effects of melatonin have been reported; however, no investigation toward examining whether the beneficial effects of melatonin are associated with preadipocyte heterogeneity has been reported. In this study, we profiled 25 071 transcriptomes of normal and melatonin-treated preadipocytes using scRNA-seq. By tSNE analysis, we present a cellular-state landscape for melatonin-treated preadipocytes that covers multiple-cell subpopulations, defined as cluster 0 to cluster 13. Cluster 0 and cluster 1 were the largest components of normal and melatonin-treated preadipocytes, respectively. G0S2, an inhibitor of adipose triglyceride lipase (ATGL), was significantly upregulated in cluster 0 and downregulated in cluster 1. We redefined cluster 0 as the G0S2-positive cluster (G0S2+ ) and cluster 1 as the G0S2-negative cluster (G0S2- ). Through pseudotime analysis, the G0S2- cluster cell differentiation trajectory was divided into three major structures, that is, the prebranch, the lipid catabolism branch, and the cell fate 2 branch. In vitro, G0S2 knockdown enhanced the expression levels of ATGL, BAT markers and fatty acid oxidation-related genes, but inhibited C/EBPα and PPARγ expression. In vivo, knockdown of G0S2 reduced the body weight gain in high-fat-fed mice. The beneficial effects of the G0S2- cell cluster in promoting lipolysis and inhibiting adipogenesis are dependent on two major aspects: first, downregulation of the G0S2 gene in the G0S2- cluster, resulting in activation of ATGL, which is responsible for the bulk of triacylglycerol hydrolase activity; and second, upregulation of FABP4 in the G0S2- cluster, resulting in inhibition of PPARγ and further reducing adipogenesis.

Abstract
As the world population grows, muscle atrophy leading to muscle wasting could become a bigger risk. Long noncoding RNAs (lncRNAs) are known to play important roles in muscle growth and muscle atrophy. Meanwhile, it has recently come to light that many putative small open reading frames (sORFs) are hidden in lncRNAs; however, their translational capabilities and functions remain unclear. In this study, we uncovered 104 myogenic-associated lncRNAs translated, in at least a small peptide, by integrated transcriptome and proteomic analyses. Furthermore, an upstream ORF (uORF) regulatory network was constructed, and a novel muscle atrophy-associated lncRNA named SMUL (Smad ubiquitin regulatory factor 2 [SMURF2] upstream lncRNA) was identified. SMUL was highly expressed in skeletal muscle, and its expression level was downregulated during myoblast differentiation. SMUL promoted myoblast proliferation and suppressed differentiation in vitro. In vivo, SMUL induced skeletal muscle atrophy and promoted a switch from slow-twitch to fast-twitch fibers. In the meantime, translation of the SMUL sORF disrupted the stability of SMURF2 mRNA. Mechanistically, SMUL restrained SMURF2 production via nonsense-mediated mRNA decay (NMD), participating in the regulation of the transforming growth factor β (TGF-β)/SMAD pathway and further regulating myogenesis and muscle atrophy. Taken together, these results suggest that SMUL could be a novel therapeutic target for muscle atrophy.

Abstract
AIMS Previous studies have shown that the forkhead transcription factor FoxO6 involved in memory consolidation and hepatic glucose homeostasis. Here we asked whether chicken FoxO6 may regulate preadipocyte proliferation, apoptosis and early adipogenesis. MAIN METHODS Overexpression and knockdown of FoxO6 were performed and evaluated through cell proliferation methods, Oil-Red-O staining, and specific marker expression. Chromatin immunoprecipitation (ChIP) assay was performed to confirm cyclin G2 (CCNG2) as a direct target gene of FoxO6. KEY FINDINGS FoxO6 is ubiquitously expressed in different chicken tissues and highly expressed in liver, abdominal fat, and preadipocytes in cultured cell. FoxO6 overexpression decreased preadipocyte proliferation by causing G1-phase cell-cycle arrest, whereas inhibition of FoxO6 showed the opposite effects. Overexpression or knockdown of FoxO6 significantly altered the mRNA and protein levels of cell-cycle related markers, such as CCNG2, cyclin dependent kinase inhibitor 1B (CDKN1B), cyclin dependent kinase inhibitor 1A (CDKN1A) and cyclin D2 (CCND2). During preadipocyte proliferation, FoxO6 targets and induces expression of CCNG2, as confirmed by ChIP assay and qPCR. In addition, FoxO6 induces preadipocyte apoptosis through increasing the protein expression levels of cleaved caspase-3 and cleaved caspase-8. Moreover, FoxO6 at the early stage of adipogenesis suppressed mRNA and protein levels of the key early regulators of adipogenesis, such as PPARγ and C/EBPα. SIGNIFICANCE The results demonstrate that FoxO6 controls preadipocyte proliferation, apoptosis and early adipogenesis, and point to new approaches for further studies related to obesity.

Abstract
Proliferation and differentiation of preadipocyte are essential for the formation of fat tissues. However, the genes that regulate the early stage of preadipocyte differentiation in chicken have remained elusive. Here we identify a novel spliced variant of the DNA methyltransferase Dnmt3a gene, named Dnmt3a3, that controls early preadipocyte differentiation. Dnmt3a3 expression is increased at the onset of preadipocyte differentiation and remains elevated during differentiation. Overexpression of Dnmt3a3 in preadipocytes markedly inhibits proliferation and cell-cycle progression, and this is accompanied by inhibition of the mRNA and protein level of cell-cycle control genes, such as p21 and p27. In addition, forced expression of Dnmt3a3 in differentiating preadipocytes represses early preadipocyte differentiation, and this was found to be accompanied by inhibition of the mRNA expression levels of early preadipocyte differentiation markers, such as GATA2, GATA3, C/EBPα, C/EBPβ, AP2, and PPARγ, or the protein levels of GATA3, C/EBPβ, and PPARγ. Taken together, these data demonstrate the participation of Dnmt3a3 in the proliferation and differentiation process of chicken primary preadipocyte cells.

Abstract
BACKGROUND Recent studies indicate important roles for long noncoding RNAs (lncRNAs) in the regulation of gene expression by acting as competing endogenous RNAs (ceRNAs). However, the specific role of lncRNAs in skeletal muscle atrophy is still unclear. Our study aimed to identify the function of lncRNAs that control skeletal muscle myogenesis and atrophy. METHODS RNA sequencing was performed to identify the skeletal muscle transcriptome (lncRNA and messenger RNA) between hypertrophic broilers and leaner broilers. To study the 'sponge' function of lncRNA, we constructed a lncRNA-microRNA (miRNA)-gene interaction network by integrated our previous submitted skeletal muscle miRNA sequencing data. The primary myoblast cells and animal model were used to assess the biological function of the lncIRS1 in vitro or in vivo. RESULTS We constructed a myogenesis-associated lncRNA-miRNA-gene network and identified a novel ceRNA lncRNA named lncIRS1 that is specifically enriched in skeletal muscle. LncIRS1 could regulate myoblast proliferation and differentiation in vitro, and muscle mass and mean muscle fibre in vivo. LncIRS1 increases gradually during myogenic differentiation. Mechanistically, lncIRS1 acts as a ceRNA for miR-15a, miR-15b-5p, and miR-15c-5p to regulate IRS1 expression, which is the downstream of the IGF1 receptor. Overexpression of lncIRS1 not only increased the protein abundance of IRS1 but also promoted phosphorylation level of AKT (p-AKT) a central component of insulin-like growth factor-1 pathway. Furthermore, lncIRS1 regulates the expression of atrophy-related genes and can rescue muscle atrophy. CONCLUSIONS The newly identified lncIRS1 acts as a sponge for miR-15 family to regulate IRS1 expression, resulting in promoting skeletal muscle myogenesis and controlling atrophy.

Abstract
Follicle-stimulating hormone (FSH) and its receptor play a key role in the follicular development and regulation of steroidogenesis in the ovary and spermatogenesis in the testis. The purpose of this study was to characterize themuscovy duck FSHR gene, identify SNPs and their association with egg production traits in muscovy ducks. Here, we cloned the complementary DNA (cDNA) sequence of FSHR, and examined the expression patterns of FSHR gene in adult female muscovy duck tissues. The cloned cDNA of the muscovy duck FSHR gene shared high similarity to those of pekin duck (Anas platyrhynchos) (95.7%) and chicken (93.2%). Three different muscovy duck FSHR transcripts were identified. Quantitative real-time PCR (RT-qPCR) results showed that the FSHR gene was expressed in all the 14 tested tissues, and the highest expression level was seen in the ovary. A total of 16 SNPs were identified, among which, four SNPs were located in the coding region of FSHR. The SNP C320T is significantly associated with egg production at 59 weeks of age (P < 0.05), whereas the SNP A227G is significantly associated with age at first egg stage (P < 0.05). These results suggest that the two SNPs (A227G and C320T) of FSHR gene are associated with egg production traits and could be potential markers that can be used for marker-assisted selection programmes to increase egg production in muscovy duck.

Abstract
MicroRNAs (miRNAs) are non-coding RNAs that regulate mRNA expression by degradation or translational inhibition. We investigated the underlying molecular mechanisms of skeletal muscle development based on differentially expressed genes and miRNAs. We compared mRNA and miRNA from chicken skeletal muscle at embryonic day E11, E16 and one day post-hatch (P1). The interaction networks were constructed, according to target prediction results and integration analysis of up-regulated genes with down regulated miRNAs or down-regulated genes with up-regulated miRNAs with |log2fold change| ≥ 1.75, P < 0.005. The miRNA-mRNA integration analysis showed high number of mRNAs regulated by a few number of miRNAs. In the E11_VS_E16, comparison group we identified biological processes including muscle maintenance, myoblast proliferation and muscle thin filament formation. The E11_VS_P1 group comparison included negative regulation of axon extension, sarcomere organization, and cell redox homeostasis and kinase inhibitor activity. The E16_VS_P1 comparison group contained genes for the negative regulation of anti-apoptosis and axon extension as well as glomerular basement membrane development. Functional in vitro assays indicated that over expression of miR-222a and miR-126–5p in DF-1 cells significantly reduced the mRNA levels of the target genes CPEB3 and FGFR3, respectively. These integrated analyses provide several candidates for future studies concerning miRNAs-target function on regulation of embryonic muscle development and growth.

Abstract
The growth and development of skeletal muscle is regulated by proteins as well as non-coding RNAs. Circular RNAs (circRNAs) are universally expressed in various tissues and cell types, and regulate gene expression in eukaryotes. To identify the circRNAs during chicken embryonic skeletal muscle development, leg muscles of female Xinghua (XH) chicken at three developmental time points 11 embryo age (E11), 16 embryo age (E16) and 1 day post hatch (P1) were performed RNA sequencing. We identified 13,377 circRNAs with 3,036 abundantly expressed and most were derived from coding exons. A total of 462 differentially expressed circRNAs were identified (fold change > 2; q-value < 0.05). Parental genes of differentially expressed circRNAs were related to muscle biological processes. There were 946 exonic circRNAs have been found that harbored one or more miRNA-binding site for 150 known miRNAs. We validated that circRBFOX2s promoted cell proliferation through interacted with miR-206. These data collectively indicate that circRNAs are abundant and dynamically expressed during embryonic muscle development and could play key roles through sequestering miRNAs as well as other functions.

Abstract
The goal of this study was to perform a systematic transcriptome-wide analysis of mRNA-miRNA interactions and to identify candidates involved in the interplay between miRNAs and mRNAs that regulate chicken muscle growth. We used our previously published mRNA (GSE72424) and miRNA (GSE62971) deep sequencing data from two-tailed samples [i.e., the highest (h) and lowest (l) body weights] of Recessive White Rock (WRR) and Xinghua (XH) chickens to conduct integrative analyses of the miRNA-mRNA interactions involved in chicken skeletal muscle growth. A total of 162, 15, 173, and 27 miRNA-mRNA pairs with negatively correlated expression patterns were identified in miRNA-mRNA networks constructed on the basis of the WRRh vs. XHh, WRRh vs. WRRl, WRRl vs. XHl, and XHh vs. XHl comparisons, respectively. Ingenuity Pathway Analysis revealed that gene networks identified for the WRRh vs. XHh contrast were associated with developmental disorders. Importantly, the WRRh vs. XHh contrast miRNA-mRNA network was enriched in IGF-1 signaling pathway genes, including FOXO3. A dual-luciferase reporter assay showed that FOXO3 was a target of miR-142-5p. Furthermore, miR-142-5p overexpression significantly decreased FOXO3 mRNA levels and promoted the expression of growth-related genes. These data demonstrated that miR-142-5p targets FOXO3 and promotes growth-related gene expression and regulates skeletal muscle growth in chicken. Comprehensive analysis facilitated the identification of miRNAs and target genes that might contribute to the regulation of skeletal muscle development. Our results provide new clues for understanding the molecular basis of chicken growth.

Abstract
Myogenesis mainly involves several steps including myoblast proliferation, differentiation, apoptosis and fusion. Except for muscle specific regulators, few miRNAs were proved to coordinate this complex process. Here, we reported that miR-16 inhibited myoblast proliferation and promoted myoblast apoptosis by directly targeting Bcl2 and FOXO1. The expression level of miR-16 was significantly decreased in the hypertrophic pectoral muscle compared to the normal pectoral muscle in chicken. In vitro, elevating miR-16 significantly inhibited myoblast proliferation and promoted myoblast apoptosis, resulting in about 11.2% cells arrested in G1 phase and 12.3% apoptotic cells in the early stage. Bioinformatic and biochemical analyses revealed Bcl2 and FOXO1 as direct targets of miR-16. Consist to the effect of miR-16 on myogenesis, specific inhibition of Bcl2 or FOXO1 significantly suppressed myoblast proliferation and induced myoblast apoptosis, indicating that both Bcl2 and FOXO1 contributed to miR-16 regulatory function in myogenesis. Interestingly, FOXO1, as the core target, mediated multiple growth-related pathways induced by miR-16 such as PI3K-AKT-MAPK and PI3K-AKT-mTOR. Chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-seq) revealed that 234 annotated genes bound by FOXO1 in the early-differentiated myoblasts, which were significantly enriched in myogenic proliferation, death and hypotrophy. Altogether, we proposed that miR-16 acted as a coordinated mediator to suppress myogenesis in avian through the control of myoblast proliferation and apoptosis. These findings have provided a novel mechanism whereby miR-16 represses Bcl2 and FOXO1 expression to maintain myoblast growth and skeletal muscle mass.

Abstract
Avian leukosis virus subgroup J (ALV-J) is an oncogenic retrovirus that has a similar replication cycle to multiple viruses and therefore can be used as a model system for viral entry into host cells. However, there are few reports on the genes or microRNAs (miRNAs) that are responsible for the replication of ALV-J. Our previous miRNA and RNA sequencing data showed that the expression of miR-34b-5p was significantly upregulated in ALV-J-infected chicken spleens compared to non-infected chicken spleens, but melanoma differentiation-associated gene 5 (MDA5) had the opposite expression pattern. In this study, a dual-luciferase reporter assay showed that MDA5 is a direct target of miR-34b-5p. In vitro, overexpression of miR-34b-5p accelerated the proliferation of ALV-J-infected cells by inducing the progression from G2 to S phase and it promoted cell migration. Ectopic expression of MDA5 inhibited ALV-J-infected cell proliferation, the cell cycle and cell migration, and knockdown of MDA5 promoted proliferation, the cell cycle and migration. In addition, during ALV-J infections, MDA5 can detect virus invasion and it triggers the MDA5 signaling pathway. MDA5 overexpression can activate the MDA5 signaling pathway, and thus it can inhibit the mRNA and protein expression of the ALV-J env gene and it can suppress virion secretion. In contrast, in response to the knockdown of MDA5 by small interfering RNA (siRNA) or an miR-34b-5p mimic, genes in the MDA5 signaling pathway were significantly downregulated (P < 0.05), but the mRNA and protein expression of ALV-J env and the sample-to-positive ratio of virion in the supernatants were increased. This indicates that miR-34b-5p is able to trigger the MDA5 signaling pathway and affect ALV-J infections. Together, these results suggest that miR-34b-5p targets MDA5 to accelerate the proliferation and migration of ALV-J-infected cells, and it promotes ALV-J replication, via the MDA5 signaling pathway.

Abstract
In the poultry industry, aggressive behaviour is a large animal welfare issue all over the world. To date, little is known about the underlying genetics of the aggressive behaviour. Here, we performed a genome-wide association study (GWAS) to explore the genetic mechanism associated with aggressive behaviour in chickens. The GWAS results showed that a total of 33 SNPs were associated with aggressive behaviour traits (P < 4.6E-6). rs312463697 on chromosome 4 was significantly associated with aggression (P = 2.10905E-07), and it was in the intron region of the sortilin-related VPS10 domain containing receptor 2 (SORCS2) gene. In addition, biological function analysis of the nearest 26 genes around the significant SNPs was performed with Ingenuity Pathway Analysis. An interaction network contained 17 genes was obtained and SORCS2 was involved in this network, interacted with nerve growth factor (NGF), nerve growth factor receptor (NGFR), dopa decarboxylase (L-dopa) and dopamine. After knockdown of SORCS2, the mRNA levels of NGF, L-dopa and dopamine receptor genes DRD1, DRD2, DRD3 and DRD4 were significantly decreased (P < 0.05). In summary, our data indicated that SORCS2 might play an important role in chicken aggressive behaviour through the regulation of dopaminergic pathways and NGF.

Abstract
The study describes the epidemiological and clinical features of whooping cough among eighty one Sudanese children (42 cases and 39 contacts aged below fifteen years) within 37 households who were under surveillance for a period of over six months. Using Khartoum Children's Emergency Hospital as the entry point, eleven patients were initially enrolled between July 1989 and August 1990 and led to the identification of another twenty six cases during home surveys. Subsequently, five of their contacts became secondary cases. The clinical criteria adopted by the Expanded Programme on Immunisation of the World Health Organization were used to identify the total of forty two cases included in the study. They were predominantly females (male: female ratio of 1:1.6), twenty (47.6%) were under five years of age and eight (19%) were infants. The attack rate was significantly higher among unimmunised infants (100%) compared to unimmunised children aged ten years and above (14.3%, p = 0.001). Half of the patients were from periurban areas, the majority (83.3%), were living in crowded households (room index > 5) and the primary immunisation rate was low (2.8%). Abnormal chest x-ray findings were detected in 26 (68.4%) patients and consisted mainly of bronchovascular thickening observed in 50%. During the follow-up period, a trend towards drop in patients' weight was observed. In four weeks, thirty (71.4%) children had a mean loss of 0.4 kg whereas eleven (26.2%) had static weight. A group of fifteen cases showed significant decrease in weight when compared to a control group of contacts that had been matched for age, sex and socio-economic status (p = 0.0001).
