Effects of maternal Escherichia coli lipopolysaccharide exposure on offspring: insights from lncRNA analysis in laying hens.

ABSTRACT: Parental living environment significantly impacts on offspring, yet related studies are lacking in livestock and poultry production. The present study found that lipopolysaccharide (LPS, Escherichia coli, 0.2 mg/kg) stimulation in F0 hens led to growth retardation and a decrease in egg-laying rate in the unchallenged F1 hens. Using strand-specific transcriptomic data of peripheral blood mononuclear cells (PBMCs) in F1 hens, we identified 100 differentially expressed lncRNAs (DELs) and 452 differentially expressed genes (DEGs). LPS primarily affected the metabolic pathways of the offspring, possibly reducing the egg-laying rate of the F1 hens by inhibiting the ferroptosis signaling pathway and the expression of DEGs involved, such as NCOA4, SLC40A1, STEAP3, and TFRC.
