Transcriptome analysis of Lactobacillus rhamnosus GG strain treated with prebiotic - bovine lactoferrin under a cold environment.

ABSTRACT: Lactoferrin (LF) is secreted by mammals and displays extensive biological effects. We previously reported that bovine LF (BLF) can boost the cold tolerance of a well-applied probiotic strain, Lactobacillus rhamnosus GG (LGG), to grow robustly under a cold environment, but the molecular mechanism is not clear. Here, RNA-seq analysis was conducted to ascertain molecular pathways underlying cold tolerance exerted by BLF. LGG was cultured in a cold environment (22 °C) in the presence or absence of BLF. Transcriptome analysis indicated that BLF significantly elicited 1.2-3.2 fold (log2 Fold change) higher expression levels of genes related to stress, defense, cell division, and transporter in LGG, including the genes CspA, LytR, XRE, MerR, and GpsB. The KEGG pathway and GO analyses confirmed th
