Abstract
ABSTRACT This study was conducted to test the expression profiles of miRNAs in the liver in piglets after the LPS challenge using sequencing technology. Twelve barrows were assigned to two groups, including the saline group and the LPS group. Six small RNA (sRNA) libraries were constructed, and novel miRNAs were identified using mirevo and mirdeep2 software and validated by quantitative real-time PCR (qRT-PCR). The results showed the mRNA expression of IL-1β, IL-6 and TNF-α in the liver increased after the LPS challenge (P < .05). A total of 29 differentially expressed miRNAs were identified in the liver after the LPS challenge. And 11 miRNAs were validated by qRT-PCR. In addition, the results of statistics of pathway enrichment showed that these miRNAs could be related to lipid metabolism response. This study provides the first miRNA expression profiles of LPS-mediated changes in the liver, which might provide potential insights into miRNAs involved in regulating lipid metabolism in pigs challenged by LPS.
期刊介绍:
Food and Agricultural Immunology is an international open access journal publishing original immunological research with applications in food, agricultural, environmental and veterinary science. Submissions describing the use of immunological techniques and methods are particularly welcomed.
The journal aims to expand our understanding of the interactions at the interface of food and immune systems including studies on:
-Development of diagnostic systems – all types of ligand-based assays, e.g. antibody, aptamer
-Application of ligand-based assays for the detection or identification of molecules of interest in food science, agricultural research, veterinary investigations and clinical systems relating to food allergy or sensitivity to agricultural chemicals
-Effects of food on the immune system
-Studies on allergy and allergic reactions
-Investigations into food allergies
-Development of allergen-free food systems
-Development of novel assay formats
-Applications of assay systems to the monitoring of food items in relation to safety and labelling
-Food quality issues, e.g. speciation, adulteration and contamination
-Comparisons between different analytical techniques
The journal publishes research and review articles and is essential reading for food scientists, immunologists and all those concerned with the interaction between food and immune systems.
