Meanwhile, HECP blocked phosphorylation of nuclear factor-κB (NF-κB) p65, NF-κB inhibitor alpha (IκB-α), mitogen-activated protein kinases (MAPK) and Protein kinase B (Akt) in DSS-treated mice.
Intracerebroventricular CMT-3 significantly inhibited Ang II-induced increases in number of microglia, their activation, and proinflammatory cytokines in the paraventricular nucleus of hypothalamus.
A microarray gene expression profile of the colon from DSS-treated ANGPTL4<sup>-/-</sup> mice was enriched for genes involved in leukocyte migration and infiltration, and showed a close association to inflamed ulcerative colitis (UC), whereas the profile from ANGPTL4<sup>+/+</sup> littermates resembled that of non-inflamed UC biopsies.
RT-PCR assays from colon showed that T. crassiceps-infected mice displayed increased expression of Arginase-1 but decreased expression of iNOS compared to DSS-treated uninfected mice.
The levels of Clock, brain and muscle arnt-like protein 1 (Bmal1), reverse orientation c-erb A gene (Rev-Erb)α, RAR-related orphan receptor gamma (RORγt), and interleukin (IL)-17 in the colon were increased by UVB eye irradiation in the DSS-treated mice (UVB/DSS-treated mice).
The immunohistochemistry results revealed that DSS significantly enhanced the expression of Bcl-2, and inhibited the expression of Bax and caspase-3 in the brain in comparison to the model group.
Supporting the observation of DSS treatment inducing colonic cell apoptosis, Bcl-2, an anti-apoptotic protein known to be regulated by c-Myb, was reduced in colon tissue of DSS-treated mice.
Analysis of the expression of the proinflammatory cytokines interleukin (IL)-1β, tumour necrosis factor (TNF)-α and IL-6 revealed no significant differences between DSS-treated Bcl-3(-/-) and wild-type mice.
Notably, increased C3b opsonization of mucosa-attached bacteria and decreased fecal full-length C3 protein was observed in DSS-treated compared to untreated mice.
The DSS phenotype of CGRP receptor-deficient mice could be adoptively transferred to wild-type (WT) mice, suggesting that CGRP suppresses the colitogenic activity of bone marrow-derived cells.
The immunohistochemistry results revealed that DSS significantly enhanced the expression of Bcl-2, and inhibited the expression of Bax and caspase-3 in the brain in comparison to the model group.
In addition, RGO supplementation induced the activity of primary antioxidant enzymes such as superoxide dismutase and catalase as well as the expression of nuclear factor erythroid 2-related factor 2-mediated antioxidant enzyme hemeoxygenase-1 in the colons of AOM/DSS-treated mice.
Surprisingly, Kaiso deficiency in the context of MTG16 loss reversed injury and pro-tumorigenic responses in the intestinal epithelium following AOM/DSS treatment, and tumor numbers were returned to near to wild-type levels.
CT-1 administration to DSS-treated mice ameliorated both the clinical course (disease activity index), histological damage, inflammation (colon expression of TNF-α, IL-17, IL-10, INF IFN-γ, and iNOS), and apoptosis.
Furthermore, CD98 was highly upregulated in colonic tissues from mice with active colitis induced by dextran sodium sulfate (DSS), but not in DSS-treated INF gamma -/- mice.
Molecular and cellular analyses revealed a link between expression of calprotectin (S100a8/S100a9), Ccl11 expression, and eosinophil numbers in the DSS-treated colon.
DSS treated-P2ry6<sup>-</sup><sup>/</sup><sup>-</sup> mice showed increased histological damage and increased neutrophil and macrophage infiltration that correlated with increased mRNA levels of the chemokines KC and MCP-1.
Furthermore, 6G and SZ suppresses immunoexpression of tumor necrosis factor alpha, interleukin-1β, inducible nitric oxide synthase, Regulated on activation, normal T cell expressed and secreted (RANTES), and Monocyte chemoattractant protein-1 (MCP-1) in the DSS-treated mice.
CD68 and F4/80 expressions were down-regulated and showed restricted infiltration to inflamed colon, while IL-17F levels were insignificantly different from the DSS treated mice.
