| Summary: | Arthritis is a leading cause of economic loss in livestock farming including sheep. This study examined the changes in gene expression, antioxidants, pro-inflammatory cytokines, acute-phase proteins (APPs), hormonal assays and iron profiles linked to sheep arthritis, as well as the diagnostic utility of these markers. Blood samples were obtained from 30 apparently healthy rams and 30 rams with arthritis for gene expression and biochemical analyses. Gene expression intensities were much higher in the arthritis-affected rams than in the healthy ones for the genes <i>IL-1α</i>, <i>IL-1β</i>, <i>IL-6</i>, <i>IL-10</i>, <i>TNFα</i>, <i>NCF4</i>, <i>NFKB</i>, <i>TMED</i>, <i>FCAMR</i>, <i>iNOS</i> and <i>COX18</i>. The <i>SOD3</i>, <i>CAT</i>, <i>GPX</i> and <i>ATOX1</i> genes were expressed at substantially lower levels in arthritis-affected rams. Disparities in the nucleotide sequence variants for the amplified DNA bases linked to arthritis for the studied genes were found in the PCR-DNA sequence verdicts of the affected and healthy rams. Immunological, acute-phase protein (APP), antioxidant, hormonal and iron profiles were estimated in both groups and statistically analyzed. The arthritic group in relation to the healthy one showed a significant (<i>p</i> < 0.05) increase in pro-inflammatory cytokines, APPs, free radicals, immunoglobulins, cortisol, GH, TSH, ferritin, TIBC and UIBC and a significant (<i>p</i> ˂ 0.05) decrease in anti-inflammatory cytokines, antioxidants, complements, insulin, T3, T4, SI, and Tf and Tf sat.% serum levels. The estimated pro-inflammatory cytokines and APPs achieved high values of sensitivity and specificity, positive predictive values (PPVs), negative predictive values (NPVs), a high accuracy rate and a moderate likelihood ratio (LR). The study concluded that ovine arthritis stimulates innate and humeral immunity, resulting in prominent alterations in gene expression, pro-inflammatory cytokines, APP assays and antioxidant profiles, which could be valuable indicators of sheep arthritis. |
