The mRNA expression levels of IL-8, NFkB, TNFα, and Caspase relative to β-actin housekeeping gene in O. niloticus fed on non-supplemented or fed with BIO-ZnNPs-30 mg/kg, or BIO-ZnNPs-60 mg/kg supplemented diets for 8 eeks. Data were represented as Mean ± SEM. Values with a different letter superscript are significantly different between groups (ANOVA with post hoc Tukey test, *P (<0.05), **P (<0.01). ***P (<0.001)
