Special Issue Information

Dear Colleagues,

Animal proteomics still remain a narrow field of interest despite their promising potential scientific values. As such, animal proteomics include veterinary-related health aspects, experimental disease and pathogenic studies, laboratory animal studies, drug testing, and understanding genotype–phenotypes. Animal proteomics can also be rapid analyzing parameters for animal product-related policy matters such as meat testing, proteins of milk and other body fluids, such as saliva, sera.

One of the major challenges in animal proteomics is the presence of several abundant proteins such as albumins and globulins, which were thought to generally interfere with the analysis of low abundant proteins. Identification of proteins with low abundance and a low copy number is difficult despite the fact that these proteins might be involved in greater significant biochemical activities—for instance, the role of hormones. Depletion or reduction in the dynamic range of proteins is recommended for investigations on low abundant proteins, which was once referred to as democratization of proteins.

Original manuscripts and review articles dealing with the following wide range of research and applications are invited for this Special Issue on “Animal Proteomics”:

  1. Identification of animal proteins in diseased domestic animals, poultry, and aquaculture-related issues;
  2. Experimental reports on protein expressional level influence of drugs, vaccines, and induced diseases and infections;
  3. Proteomics investigations of milk, animal fluids, and animal products;
  4. Application of proteomics in rapid testing on animal product adulterations, especially milk and meat products;
  5. Role of protein level investigations on animal feeds and influence on commercial ventures such as poultry, animal husbandry, and aquaculture;
  6. Development of protein related therapeutic agents, designing proteome-based newer vaccine candidates and diagnostic tools;
  7. Role of proteomics in decision and policy making of animal related issues.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Snake venom is an extremely interesting natural mixture of proteins and peptides, characterized by both high diversity and high pharmacological potential. Much attention has been paid to the study of venom composition of different species and also detailed analysis of the properties of individual components. Since proteins and peptides are the active ingredients in venom, rapidly developing proteomic techniques are used to analyze them. During such analyses, one of the routine operations is to measure the protein concentration in the sample. The aim of this study was to compare five methods used to measure protein content in venoms of two snake species: the Viperids representative, Agkistrodon contortrix, and the Elapids representative, Naja ashei. The study showed that for A. contortrix venom, the concentration of venom protein measured by four methods is very similar and only the NanoDrop method clearly stands out from the rest. However, in the case of N. ashei venom, each technique yields significantly different results. We hope that this report will help to draw attention to the problem of measuring protein concentration, especially in such a complex mixture as animal venoms. Full article

Abstract
This study investigated the proteomic characteristics of colostrum for sows housed under different conditions. Among 12 gilts, four were housed in a gestation-crate and farrowing-crate combined housing system (CC) as controls, four were housed in a gestation-pen and farrowing-pen combined housing system (PP), [...] Read more.
This study investigated the proteomic characteristics of colostrum for sows housed under different conditions. Among 12 gilts, four were housed in a gestation-crate and farrowing-crate combined housing system (CC) as controls, four were housed in a gestation-pen and farrowing-pen combined housing system (PP), and four were housed in a gestation-pen and farrowing-crate combined housing system (PC). Differentially expressed proteins in the colostrum (PP versus CC, and PC versus CC) were screened by proteomics technology, and bioinformatics analysis was then performed. Results showed that 93 proteins were differentially expressed in PP versus CC, and that 126 proteins were differentially expressed in PC versus CC. The differentially expressed proteins in the PP versus CC comparison were mainly enriched in interleukin (IL)-17, transforming growth factor-β, and nuclear factor-κ B signaling pathways, and in metabolic pathways, including glutathione metabolism, peroxisome, and carbon metabolism. In contrast, differentially expressed proteins in the PC versus CC comparison were enriched in the IL-17 signaling pathway, cholesterol metabolism, and peroxisome proliferator-activated receptor signaling pathway. In conclusion, the housing environment appeared to affect the colostrum composition of sows by acting on their immune system and metabolic processes, particularly fat metabolism. Full article
