Combining widely targeted metabolomics and RNA-sequencing to reveal the function analysis of Phyllanthus emblica Linn. Juice-induced poultry macrophages

Abstract

This study explored the functional effects of cultivated and wild Phyllanthus emblica Linn juice (PEJ) in HD11 poultry macrophage lines, with the aim of potentially developing cultivated PE and its fruit residue as poultry feed additives. RNA-Seq was used to evaluate the functional differences between cultivated and wild PEJ induced HD11 cells. Both cultivated and wild PEJ could regulate cell replication by histone H1/H2 family genes and host immune response by Toll-like receptor 7 regulation. Wild PEJ inhibited M1-type polarization of host macrophages, while cultivated PEJ promoted M2-type polarization. Metabolites of cultivated and wild PE were identified by widely targeted metabolomics based on liquid chromatography-tandem mass spectrometry. Of the 911 metabolites, 238 differed functionally between cultivated and wild PE. The data provide a theoretical basis for the subsequent development of PE as a functional feed additive in poultry.
