Abstract
Edwardsiella anguillarum is a bacterium that commonly infects cultivated eels. Outer membrane protein A (OmpA) emulsified with Freund's adjuvant has been shown to be an effective fishery vaccine against this pathogen. However, the specific roles of OmpA in the vaccine have not been fully explored. In this study, we performed RNA-seq in the liver of a European eel (Anguilla anguilla) after challenge with E. anguillarum in eels previously immunized with an OmpA subunit vaccine. Our aim was to elucidate the differentially alternative splicing (DAS) and differentially expressed long noncoding RNAs (DE-lncRNAs) using a genome-wide transcriptome. The results showed after that at 28 days post-immunization, eels challenged with E. anguillarum (Con_inf) exhibited severe pathological changes in the liver. In contrast, the OmpA infused eels (OmpA_inf group) showed infiltrated lymphocytes, while Freund's adjuvant-inoculated eels (FCIA_inf group) showed edema of hepatocytes and blood coagulation. The relative percent survival (RPS) was 77.7% and 44.4% for OmpA_inf and FCIA_inf compared to the Con_inf group. We identified 37 DE-lncRNAs and 293 DAS genes between OmpA_inf and FCIA_inf. Interactions between DAS gene-expressed proteins indicated that 66 expressed proteins formed 20 networks. Additionally, 33 DE-lncRNAs interacted with 194 target genes formed 246 and 41 networks in co-expression and co-location. Taken together, our findings demonstrate that the OmpA subunit vaccine elicits a higher RPS and provides novel insights into the role of OmpA through DAS genes and DE-lncRNAs perspective. These results are significant for the development of fishery subunit vaccines.

Abstract
Introduction: Cytokines are cell signaling glycoproteins that are particularly important in immunity and inflammatory responses. Therefore, variations, such as single nucleotide polymorphisms (SNPs), in genes encoding for cytokines may have important consequences for their roles in health. Materials and Methods: A total of 222 unrelated, healthy, and un-admixed Malays (n = 97), Chinese (n = 77), and Indians (n = 48) with a median age of 30 years old (range 21-50) were typed for 22 cytokine gene SNPs: IL-1α -889 T/C, IL-1β (-511 T/C, +3962 T/C), IL-1R pst1 1970 T/C, IL-1RA mspa1 11100 T/C, IL-4Rα +1902 G/A, IL-12 - 1188 C/A, IFN-γ +874 A/T, TGF-β (cdn 10 C/T, cdn 25 G/C), TNF-α (-308 A/G, -238 A/G) IL-2 (+166 G/T, -330 T/G), IL-4 (-1098 T/G, -590 T/C, -33 T/C), IL-6 (-174 C/G, nt565 G/A), and IL-10 (-1082 G/A, -819 C/T, -592 A/C). This involved using well-established polymerase chain reaction procedures with sequence-specific primers and restriction fragment length polymorphism methods. Results: The majority of the screened cytokine gene SNPs are polymorphic in all three ethnicities. Exceptions include TGF-β cdn 25 (G/C), IL-1β +3962 (T/C), and TNF-α -238 (A/G), which were all observed to be monomorphic in Malays, Chinese and Indians. Many of the analyzed cytokine gene SNP genotypes deviated from Hardy-Weinberg equilibrium and the three ethnic study groups were all well-separated from reference Asian, African and European populations in a principal component analysis plot. Conclusion: We successfully typed 22 SNPs in 13 cytokine genes from genetic material collected from unrelated and un-admixed Malay, Chinese and Indian individuals in Peninsular Malaysia. These new cytokine gene population datasets reveal interesting contrasts with other populations.

Abstract
Background: This study explored the correlation between the interleukin-1β gene rs16944 polymorphism and diabetes through epidemiological and follow-up investigations.Methods: The study was conducted on 600 subjects with normal glucose metabolism recruited from participants of the Risk Evaluation of cAncers in Chinese type 2 diabeTic Individuals: A lONgitudinal (REACTION) study in Luzhou, China in 2011. All subjects received a unified standardized questionnaire, physical examination, laboratory examination, and follow-up in 2016. Subjects were divided into normal glucose metabolism (NC), pre-diabetes (PDM), and type 2 diabetes mellitus (T2DM) groups according to their glucose metabolism after follow-up. The IL-1β gene rs16944 polymorphism was analyzed using the polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) technique.Results: After follow-up, 386, 156, and 58 cases were observed in the NC, PDM, and T2DM groups, respectively. Serum IL-1β levels were compared to baselines at follow-up in the 3 groups; the difference in the T2DM group was statistically significant. The frequency distributions of the IL-1β gene rs16944 genotypes, i.e., CC, CT, and TT, were significantly different in the 3 groups, and the distributions in the T2DM and NC groups were significantly different. The frequency distributions of the C and T alleles of IL-1β rs16944 were not significantly different. Logistic regression analysis identified the CC+CT genotype as an independent risk factor for the development of diabetes in patients with normal glucose metabolism (OR = 2.457, 95% CI: 1.238-4.877).Conclusions: The IL-1β gene rs16944 C/T polymorphism may cause genetic susceptibility to T2DM in the Luzhou population. The CC+CT genotypes may increase T2DM risk.
