In this study, we deciphered the key mechanism by which DATS alleviates ulcerative colitis (UC). We showed that oral administration of DATS for 10 consecutive days greatly restrained the infiltration of macrophages and the pathological changes in colonic tissues of mice with DSS-induced colitis. DATS treatment notably dampened the content of IL-1β and IL-18 and suppressed NLRP3 inflammasome activation in colon. Mechanistically, DATS effectively diminished the generation of ROS in macrophages. The suppressive effect of DATS on the activation of NLRP3 inflammasome and downregulation of IL-18 and IL-1β levels was blunted by xanthine oxidase. Further studies revealed that DATS inhibited NF-κB pathway activation by suppressing the expression of Trx-1, thereby inhibiting NLRP3 inflammasome activation. Trx-1 overexpression and interference in macrophages promoted and diminished NLRP3 inflammasome activation, respectively.

The aim of this study is to evaluate the role of DPG administration in preventing lipopolysaccharide (LPS)-induced damage in the female genital system. Thirty-two female Wistar Albino rats were randomly allocated into four groups: control group, LPS group, LPS + DPG group and DPG group. At the end of the experimental phase, ovary, fallopian tube and uterus tissues were collected for histopathological, immunohistochemical, genetic and biochemical analyses. The findings showed that LPS caused histopathological changes characterized by marked hyperaemia, mild to moderate haemorrhage, oedema and neutrophil leucocyte infiltrations and degenerative and necrotic changes in the female genital tract. In addition, it decreased total antioxidant status (TAS), increased total oxidant status (TOS) and oxidative stress index (OSI) levels. LPS also increased the expressions of Cas-3, G-CSF and IL-1β in the ovary, fallopian tubes and uterus immunohistochemically. While Claudin-1 expression decreased, NLRP3 and AQP4 gene expressions increased due to LPS. However, DPG treatment prevented all these changes.
