β-Hydroxybutyrate (BOHB) increased the expression of genes encoding enzymes related to ketolytic pathways and genes that phenocopy caloric restriction responses. (A) Diagram illustrating the treatment of bovine skin fibroblasts for 96 h with 2 mM of BOHB to mimic levels attained systemically by ketotic cows. (B) Quantification of transcripts in bovine skin fibroblasts cultured either with (2 mM) or without (control) BOHB for 96 h. Transcript quantities were normalized to the geometric mean of three housekeeping genes (GUSB, PPIA and RPL15). Data are presented as fold change in relation to the control group, and the values are shown as the mean ± s.e.m. Gene expression data from 5 biological replicates. Different letters indicate a significant difference (P < 0.05).
