Article Abstract
Prostaglandin E-major urinary metabolite (PGE-MUM) is a valuable biomarker reflecting the cytokine profile. We encountered a case of a 14-year-old boy with pan-colitis-type ulcerative colitis who was unresponsive to steroids and infliximab. The patient's clinical symptoms gradually deteriorated and surgical treatment was strongly considered because anti-inflammatory therapy was unlikely to be effective. PGE-MUM levels were markedly elevated, indicating a T-helper 17 (Th17)-like cytokine profile. Because an antibody against interleukin 23 (IL-23) was presumed to be effective, the patient was treated with mirikizumab, after which he achieved remission. In the present case, measurement of PGE-MUM levels was useful in selecting anti-cytokine treatments for severe ulcerative colitis.

Objectives: To investigate the therapeutic mechanism of 2,6-dimethoxy-1,4-benzoquinone (DMQ) for alleviating dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice.
Methods: Eighteen male C57BL/6J mice were equally randomized into control group, DSS group and DMQ treatment group. In DSS and DMQ groups, the mice were treated with DSS in drinking water to induce UC, and received intraperitoneal injections of sterile PBS or DMQ (20 mg/kg) during modeling.

Objective: This study aims to elucidate how butyrate, a short-chain fatty acid, regulates the Treg/Th17 balance in ulcerative colitis (UC) via the cAMP-PKA/mTOR signaling pathway, offering novel treatment strategies.
Methods: Dextran sulfate sodium (DSS) was used to induce ulcerative colitis in a mouse model. Various butyrate dosages were administered to the mice.

Ulcerative colitis (UC), a chronic inflammatory bowel disease (IBD), is characterized by disruption of intestinal barrier function and complex inflammatory manifestations locally and systemically. Although anti-tumor necrosis factor-α (TNF-α) agents such as Infliximab (IFX) are effective in treating IBD, their intestinal tissue concentration has been regarded as determinant of therapeutic efficacy while was restrained by the large molecular weight. Considering the enhanced expression of human neonatal Fc receptor (hFcRn) in UC tissues, we attempted to deliver the therapeutic entity of IFX into UC tissues by developing a novel dual-acting IFX Fab-F8 (IFX-F8) fusion protein for UC treatment.
