Antibacterial Mechanism of Silkworm Seroins

Hongtao Zhu, Xiaolu Zhang, Mengyao Lu, Haiqin Chen, Shiyi Chen, Jiaxuan Han, Yan Zhang, Ping Zhao, Zhaoming Dong
2020 Polymers  
Seroin 1 and seroin 2 are abundant in silkworm cocoon silk and show strong antibacterial activities, and thus are thought to protect cocoon silk from damage by bacteria. In this study, we characterized the expression pattern of silkworm seroin 3, and found that seroin 3 is synthesized in the female ovary and secreted into egg to play its roles. After being infected, seroin 1, 2, and 3 were significantly up-regulated in the silkworm. We synthesized the full-length protein of seroin 1, 2, and 3

All three seroins showed higher antibacterial activity against Gram-positive bacteria than against Gram-negative bacteria. Seroin 2 showed better antibacterial effect than seroin 1 and 3, whereas seroin 1/2/3-N was better than seroin 1/2/3-C. We found that seroin 2-C has stronger peptidoglycan binding ability than seroin 2-N per the ELISA test. The binding sites of seroin 2 with bacteria were blocked by peptidoglycan, which resulted in the loss of the antibacterial activity of seroin 2. Collectively, these findings suggest that seroin 1 and 2 play antibacterial roles in cocoon silk, whereas seroin 3 functions in the eggs. The three silkworm seroins have the same antibacterial mechanism, that is, binding to bacterial peptidoglycan by the C-terminal domain and inhibiting bacterial growth by the N-terminal domain.

An RGD-Containing Peptide Derived from Wild Silkworm Silk Fibroin Promotes Cell Adhesion and Spreading

Zhao Kang, Yining Wang, Jingjing Xu, Guangzhou Song, Mengyao Ding, Huanrong Zhao, Jiannan Wang
2018 Polymers  
Arginine-Glycine-Aspartate (RGD) tripeptide can promote cell adhesion when present in the amino acid of proteins such as fibronectin. In order to demonstrate the bioactivity of an RGD-containing silk protein, a gene encoding the RGD motif-containing peptide GSGAGGRGDGGYGSGSS (–RGD–) derived from nonmulberry silk was designed and cloned, then multimerised and inserted into a commercial pGEX expression vector for recombinant expression of (–RGD–)n peptides. Herein, we focus on two

Target peptides (–RGD–)4 and (–RGD–)8 (6.03 and 11.5 kDa) were cleaved from the GST-tag by thrombin digestion, as verified with MS and SDS-PAGE. Isoelectric point analysis confirmed that target peptides were expressed and released in accordance with the original design. Target peptides self-assembled into a mainly α-helical structure, as determined by circular dichroism spectroscopy. Furthermore, (–RGD–)4 and (–RGD–)8 modified mulberry silk fibroin films were more effective for rapid cell adhesion, spreading and proliferative activity of L929 cells than some chemically synthesized RGD peptides modified and mulberry silk lacking the RGD motif.

Microbiome Crosstalk in Immunotherapy and Antiangiogenesis Therapy

Xueting Wan, Mengyao Song, Aiyun Wang, Yang Zhao, Zhonghong Wei, Yin Lu
2021 Frontiers in Immunology  
The human body and its microbiome constitute a highly delicate system. The gut microbiome participates in the absorption of the host's nutrients and metabolism, maintains the microcirculation, and modulates the immune response. Increasing evidence shows that gut microbiome dysbiosis in the body not only affects the occurrence and development of tumors but also tumor prognosis and treatment. Microbiome have been implicated in tumor control in patients undergoing anti- angiogenesis therapy and

In cases with unsatisfactory responses to chemotherapy, radiotherapy, and targeted therapy, appropriate adjustment of microbes abundance is considered to enhance the treatment response. Here, we review the current research progress in cancer immunotherapy and anti- angiogenesis therapy, as well as the unlimited potential of their combination, especially focusing on how the interaction between intestinal microbiota and the immune system affects cancer pathogenesis and treatment. In addition, we discuss the effects of microbiota on anti-cancer immune response and anti- angiogenesis therapy, and the potential value of these interactions in promoting further research in this field.

Neural Network Evolving Algorithm Based on the Triplet Codon Encoding Method

Xu Yang, Songgaojun Deng, Mengyao Ji, Jinfeng Zhao, Wenhao Zheng
2018 Genes  
Artificial intelligence research received more and more attention nowadays. Neural Evolution (NE) is one very important branch of AI, which waves the power of evolutionary algorithms to generate Artificial Neural Networks (ANNs). How to use the evolutionary advantages of network topology and weights to solve the application of Artificial Neural Networks is the main problem in the field of NE. In this paper, a novel DNA encoding method based on the triple codon is proposed. Additionally, a NE

The results show that TCENNE is very effective and more robust than NE algorithms, due to the coding design. Also, it is shown that it can realize the co-evolution of network topology and weights and outperform other neural evolution systems in challenging reinforcement learning tasks.

2013 CHI '13 Extended Abstracts on Human Factors in Computing Systems on - CHI EA '13  
Achieving design inspirations can be defined as the process that how designers are ignited with design ideas. It is crucial for designers since this ability partly determines the power of their design. The awareness of what its own design practice is in HCI community calls for more studies on the nature of interaction design, design practices and designers. In this paper, I present my study on designers' design processes and design philosophy, based on empirical work with ten designers from

BS-virus-finder: virus integration calling using bisulfite sequencing data

Reviewer #1: Major Concerns 1. Why did the authors choose whole-genome bisulfite sequencing (WGBS) data for identification of the virus integration loci? There are many established tools or pipelines for detection of viral integration loci based on whole-genome sequencing (WGS) and/or RNA-seq. What is the rationale for developing a method using WGBS instead of improving upon the methods for WGS or RNA-seq for virus integration detection? Authors provide a reference, saying, "A recent clinical
more » ... udy showed that DNA methylation is associated with viral integration", but the work of Larsson GL et al, 2014 was not performed on whole-genome methylation data and hardly could be used as a rationale for using WGBS for the virus detection. Thank you for your comments. There is no existing method for analysis of virus integration by using WGBS data unless additional relative WGS and RNA-seq data is available, thus requiring more human and financial resources. Regarding this, our software tool solved this problem by finding virus integration directly from WGBS data, therefore enabling efficiently and deeply mining data. We cite the work of Larsson GL to show that there is a relationship between virus integration and DNA methylation, and not as a rationale for using WGBS.
