Therefore, this study aimed to investigate the ameliorative effect of boswellic acid coated zinc nanoparticles (BAs-ZnNPs) on dextran sodium sulphate (DSS) induced-UC in rats.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Rats were divided into five groups; control, BAs-ZnNPs, DSS, DSS+BAs, and DSS + BAs-ZnNPs. The activity of alkaline phosphatase (ALP) was determined colorimetrically, while the concentration of IgM, IgG, TNF-\u03b1, IL-1\u03b2, and IL-8 were measured by ELISA. Levels of gene expression of NF-\u03baB and COX-2 genes were evaluated by RT-qPCR, while the expression of protein levels of PI3K and STAT-3 were done by western blotting. Finally, histopathological examination of colon tissues of different groups of rats was done.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The depicted ball-like structure of the BAs-ZnNPs in the TEM images ranging in size from 50 to 100\u00a0nm in diameter while their formation was confirmed by UV\u2013visible spectroscopy with a sharp peak of maximum absorbance at 266\u00a0nm. Our results revealed that BAs-ZnNPs exerted an anti-inflammatory effect in the experimental model of colitis, demonstrated histologically and biochemically as shown by the improvement of ALP, IgM, IgG, and the gene expression levels of NF-\u03baB and COX-2. Also, this beneficial effect was associated with the reduction in the expression of TNF-\u03b1, IL-1\u03b2, IL-8, PI3K, and STAT-3. Thus, this effect improves the altered immune response associated with the colonic inflammation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>BAs-ZnNPs can be proposed as a therapeutic candidate to attenuate UC. The potential underlying mechanism includes suppression of ALP, IgM, IgG, IL-1\u03b2, and IL-8 levels via regulation of NF-\u03baB and COX-2 gene expression and STAT-3 and PI3K protein expression in a UC rat model.<\/jats:p>\n
