- Exposure to inflammation exacerbates injury in neonatal encephalopathy (NE). We hypothesized that brain biomarker mRNA, cytokine mRNA and microRNA differentiate inflammation (E. coli LPS), hypoxia (Hypoxia), and inflammation-sensitized hypoxia (LPS+Hypoxia) in an NE piglet model.Sixteen piglets were randomized: (i) LPS 2μg/kg bolus; 1μg/kg infusion (LPS; n=5), (ii) Saline with hypoxia (Hypoxia; n=6), (iii) LPS commencing 4h pre-hypoxia (LPS+Hypoxia; n=5). Total RNA was acquired at baseline, 4h after LPS and 1, 3, 6, 12, 24, 48h post-insult (animals euthanized at 48h). Quantitative PCR was performed for cytokines (IL1A, IL6, CXCL8, IL10, TNFA) and brain biomarkers (ENO2, UCHL1, S100B, GFAP, CRP, BDNF, MAPT). MicroRNA was detected using GeneChip (Affymetrix) microarrays. Fold changes from baseline were compared between groups and correlated with cell death (TUNEL) at 48h.Within 6h post-insult, we observed increased IL1A, CXCL8, CCL2 and ENO2 mRNA in LPS+Hypoxia and LPS compared to Hypoxia. IL10 mRNA differentiated all groups. Four microRNAs differentiated LPS+Hypoxia and Hypoxia: hsa-miR-23a, 27a, 31-5p, 193-5p. Cell death correlated with TNFA (R=0.69; p<0.01) at 1-3h and ENO2 (R=-0.69; p=0.01) at 48h.mRNA and miRNA differentiated hypoxia from inflammation-sensitized hypoxia within 6h in a piglet model. This information may inform human studies to enable triage for tailored neuroprotection in NE.Early stratification of infants with neonatal encephalopathy is key to provide tailored neuroprotection.IL1A, CXCL8, IL10, CCL2 and NSE mRNA are promising biomarkers of inflammation-sensitized hypoxia.IL10 mRNA levels differentiated all three pathological states; fold changes from baseline was the highest in LPS+Hypoxia animals, followed by LPS and Hypoxia at 6h.miR-23, -27, -31-5p and -193-5p were significantly upregulated within 6h of a hypoxia insult.Functional analysis highlighted the diverse roles of miRNA in the cellular processes.
