Characterization of the β-defensin genes in giant panda

Zhi-Yi Zhang, He-Min Zhang, De-Sheng Li, Tie-Yi Xiong, Sheng-Guo Fang
2018 Scientific Reports  
β-Defensins are small antimicrobial proteins expressed in various organisms and have great potential for improving animal health and selective breeding programs. Giant pandas have a distinctive lineage in Carnivora, and it is unclear whether β-defensin genes have experienced different selective pressures during giant panda evolution. We therefore characterized the giant panda (Ailuropoda melanoleuca) β-defensin gene family through gap filling, TBLASTN, and HMM searches. Among 36 β-defensins

Moreover, for DEFB139, a significant positive selection different from that of its homologs was revealed through branch model comparisons. A Pro-to-Arg mutation in the giant panda DEFB139 mature peptide may have enhanced the peptide's antimicrobial potency by increasing its stability, isoelectric point, surface charge and surface hydrophobicity, and by stabilizing its second β-sheet. Broth microdilution tests showed that the increase in net charge caused by the Pro-to-Arg mutation has enhanced the peptide's potency against Staphylococcus aureus, although the increase was minor. We expect that additional gene function and expression studies of the giant panda DEFB139 gene could improve the existing conservation strategies for the giant panda. Defensins are a group of small antimicrobial peptides (AMPs) found in large variety of plants, invertebrates, and vertebrates that act against a broad spectrum of pathogens including enveloped viruses, gram-positive and gram-negative bacteria, mycobacteria, and fungi 1 . There are three defensin subfamilies known as α, β, and θ defensins; among these, β-defensins represent the oldest family, and most mammalian β-defensins arose before the last common ancestor of eutherian mammals 1-4 . β-defensin proteins are expressed mainly by mucosal epithelial cells lining the respiratory, gastrointestinal, and genitourinary tracts, but the expression pattern and antimicrobial properties of many β-defensins remain unknown 1,4 . Apart from killing microbes directly, recent studies have discovered novel roles for β-defensins in immunology and reproduction. Navid et al. (2012) found that mouse β-defensin 14 (Defb14) can mediate the immune response by regulating T cells 5 . Human DEFB2, DEFB3, and their mouse orthologs are also chemoattractants used for recruiting immune cells to fight against infection 6 . Hardwick et al. (2011) found higher DEFB103 expression levels in the epithelial cells of people from East Asia 7 , which can increase influenza resistance in this population. In macaques, spermatozoa coated with DEFB126 are protected from attack by the female immune system, which facilitates fertilization 8, 9 . Furthermore, certain variants of some β-defensins in human and cattle are also related to fertility 8,10 . Because of these properties, several potential applications for β-defensins can be envisioned for improving animal health, including the design of antibiotics that would avoid the emergence of resistance, the development of vaccine adjuvants, dietary manipulations that enhances gut disease resistance, and selective breeding for breeds with higher fitness 1,11,12 . Giant pandas represent the 'national treasure' of China and a flagship for world wildlife conservation. These animals have received much attention not only because of their endangered status, but also because of their intriguing evolutionary history. To date, many genetic analyses have investigated the phylogeny, genetic variation, population history, adaptive evolution, and structure of this species using a combination of molecular markers including fingerprint probes, microsatellites, mitochondrial DNA, and major histocompatibility complex (MHC) loci 13 . As one of the most important disease resistance genes, MHCs in the giant panda are extensively studied to

We analyze the outcome of circumcisions performed with 8-figure non-absorbable suture (8FNS) and assess the feasibility of using the technique in male circumcision.Methods: We randomly divided 317 patients who would undergo circumcision between February 2009 and January 2012 into 2 groups. Each group was subdivided into children (age range: 7 to 15 years) and adult (range: 16 to 85 years). In the experiment group (n =166), we used 8FNS and in the control group (n = 151), commonly absorbable

Chi-square and Student's t-test were used in statistical analysis. Differences were considered significant (p < 0.05).Results: No patients were required to remove their sutures postoperatively.Among them, the sutures of the 8FNS for circumcision felloff spontaneously within 9 days (6.2 ± 1.57). There was no statisticallysignificant difference between the 2 groups in surgical duration (16.2 ± 1.73 vs. 15.8 ± 2.01) and follow-up time (6.4 ± 3.82 vs. 6.2 ± 2.39). The overall complication rate of the 2 groups was 6.63% and 10.53% (p = 0.15), respectively. In addition, the complication rate among the adults was significantly lower in the 8FNS group compared to children (2.53% vs. 10.34%, p = 0.04). Also, the average cost (in US dollars) of 8FNS for circumcision was $20.7 ± $3.83 less than $35.8 ± $5.02 of CAS, which is a very significant difference (p < 0.0001).Conclusions: 8FNS for circumcision is feasible, easy, safe and cost-effective, especially for adult males.

2012 arXiv   pre-print
It is widely accepted that the selection of measurement bases can affect the efficiency of quantum state estimation methods, precision of estimating an unknown state can be improved significantly by simply introduce a set of symmetrical measurement bases. Here we compare the efficiencies of estimations with different numbers of measurement bases by numerical simulation and experiment in optical system. The advantages of using a complete set of symmetrical measurement bases are illustrated more clearly.

Quantum illumination, that is, quantum target detection, is to detect the potential target with two-mode quantum entangled state. For a given transmitted energy, the quantum illumination can achieve a target-detection probability of error much lower than the illumination scheme without entanglement. We investigate the usefulness of noiseless linear amplification (NLA) for quantum illumination. Our result shows that NLA can help to substantially reduce the number of quantum entangled states

Nivolumab, an anti-programmed death (PD)1 IgG 4 antibody, has shown notable success as a cancer treatment. Here, we report that nivolumab was susceptible to aggregation during manufacturing, particularly in routine purification steps. Our experimental results showed that exposure to low pH caused aggregation of nivolumab, and the Fc was primarily responsible for an acid-induced unfolding phenomenon. To compare the intrinsic propensity of acid-induced aggregation for other IgGs subclasses,

The accurate pH threshold of acid-induced aggregation for individual IgG Fc subclasses was identified and ranked as: IgG 1 < aglyco-IgG 1 < IgG 2 < IgG 4 . This result was cross-validated by thermostability and conformation analysis. We also assessed the effect of several protein stabilizers on nivolumab, and found mannitol ameliorated the acid-induced aggregation of the molecule. Our results provide valuable insight into downstream manufacturing process development, especially for immune checkpoint modulating molecules with a human IgG 4 backbone.

BackgroundAbdominal aortic calcification is a potentially important independent risk factor for cardiovascular health. The aim of this study was to determine the relationship between serum chloride level and abdominal artery calcification.MethodsWe obtained the data of 3,018 individuals from the National Health and Nutrition Examination Survey database and analyzed the relationship between serum chloride and abdominal artery calcification. We performed stratified and single factor analysis,

R and EmpowerStats were used for data analysis.ResultsSerum chloride is independently related to the AAC total 24 score (AAC-24). The smooth curves fitted were all inverted-U shaped. Below a cutoff value of 92 mmol/L, increase in serum chloride level was associated with increase in AAC-24; however, above that cutoff, increase in serum chloride level was associated with decrease in AAC-24.ConclusionsAt serum levels below 92 mmol/L, chloride is a risk factor for abdominal aortic calcification but levels above 92 mmol/L appear to protect against abdominal aortic calcification.
