Interpretive Summary:

Technical Abstract: We hypothesized that maternal nutrition during the first 50 d of gestation would alter the metal-binding transcriptome of the developing cerebrum. 14 beef heifers were estrus synchronized and assigned to 2 treatments at breeding (CON-100% of requirements; RES-60% of CON). Heifers were ovariohysterectomized on d 50 of gestation and fetal cerebra were dissected, flash frozen, RNA extracted, and RNA-Sequencing conducted. Transcriptome analysis was run via the Tuxedo Suite in collaboration with USDA-ARS-MARC and gene clusters were examined with DAVID 6.8. 151 genes were utilized for cluster analysis (P<0.01; 29 q<0.10). The metal-binding cluster contained 24 genes (Enrichment Score 1.01; P=0.006; Benjamini=0.047), 4-Fe, 10-Zn, 2-Cu, and 8 for other metal binding genes. 23 metal-binding genes were upregulated in RES (Min=2.26, Max=46.29; Avg=8.28-fold greater), and 1 in CON (3.51-fold greater). Thus, maternal nutrition during the first 50 days of gestation impacted expression of metal-binding genes in bovine fetal cerebrum.
