In Vivo Model |
After 10 days of acclimation, the mice were randomly assigned to five groups (n = 6 each): control, model (3% DSS), BCP (50 mg/kg body weight), AM630 (10 mg/kg body weight) and AM630 + BCP. All mice (except those in the control group) were provided with a solution of filtered water containing 3% (w/v) DSS ad libitum during the experiment period. The mice in the control group received only normal drinking water. For the treatment groups, BCP was dissolved in corn oil at doses of 50 mg/kg and administered orally once a day. The mice in the AM630 group were injected intraperitoneally with AM630 (10 mg/kg). The mice in the AM630 + BCP group received an intraperitoneal injection of AM630 (10 mg/kg) given 30 min before the BCP (50 mg/kg). During the study, symptomatic parameters including body weight, stool character and bleeding were recorded daily. The disease activity index (DAI) was calculated according to our previous study. After 8 days of treatment, all mice were anesthetized with pentobarbital sodium. The blood and colon samples were collected for subsequent analysis. The collected blood was left to coagulate for 20 min at room temperature and centrifuged for 15 min at 3000 g to obtain the serum.

Response regulation | B-Caryophyllene (BCP) activated the type 2 cannabinoid receptor (CB2R) to inhibit macrophage ferroptosis and its induced inflammatory response both in vivo and in vitro. These results revealed that macrophage ferroptosis is a potential therapeutic target for ulcerative colitis and identified a novel mechanism of BCP in ameliorating experimental colitis. | ||||

All mice involved had a C57BL/6 gene background. All mice with age- and sex-matched between 6 and 8 weeks of age were assigned randomly to groups. To induce experimental colitis, the mice were challenged with 3% dextran sulfate sodium (DSS; MP Biomedicals, LLC, Solon, OH) in drinking water for 7 days. The control mice were allowed to drink water only at the same time. To administer ferrostatin-1 (Fer1) in vivo, we intraperitoneal injected mice daily with Fer1 (Merck, Darmstadt, Germany, 2.5 umol/kg body weight), and the corresponding control mice were injected intraperitoneally with normal saline.

C57BL/6 mice were randomly divided into two groups: control group (n = 7) and DSS group (n = 7). Mice in the DSS group were given 3.0% (w/v) dextran sulfate sodium (DSS, molecular weight, 36-50 kDa; MP Biomedicals, UK) in the drinking water for 7 days. Mice in the control group were fed with normal drinking water throughout the experimental period.

Male C57BL/6J mice (8 weeks) were housed in a controlled condition at 25 , 45-55% humidity and 12 h light/dark cycle. All mice were randomly divided into five groups: Vehicle group, mice received dextran sulfate sodium (DSS group), DSS mice received ferrostatin-1 (DSS + Fer-1 group), DSS mice received low dose of CUR (DSS + CUR-L group), and DSS mice received high dose of CUR (DSS + CUR-H group). In the experiments, 3% DSS (D122347, Aladdin, Shanghai, China) in drinking water for 7 days was prepared to induce UC models. Mice in DSS + Fer-1 group were intraperitoneally injected with 5 mg/kg Fer-1 (S7243, Selleck, Shanghai, China) every two days from the day before DSS induction. In addition, mice in DSS + CUR-L or DSS + CUR-H group received intragastric administration with CUR (HY-N0705, Med Chem Express, Shanghai, China) at 50 mg/kg or 100 mg/kg once a day for 7 days during DSS administration.

Response regulation | Curculigoside (CUR) could increase the selenium sensitivity and promote GPX4 transcription level in IEC-6 cells. Knockdown of GPX4 significantly blocked the protective effects of CUR on cell death, GSH and MDA contents as well as LDH activity in ferroptotic IEC-6 cells. Taken together, CUR protects against ferroptosis in ulcerative colitis (UC) by the induction of GPX4, which presents a potential agent for UC treatment. | ||||

Six-eight-week-old male C57BL/6 mice weighing 19.74 ± 0.77 g were purchased from Shanghai Laboratory. To investigate the therapeutic effect of APS on DSS-induced colitis, mice were randomly divided into the following 5 groups (n = 5 each): control, DSS, DSS + APS (100 mg/kg), DSS + APS (200 mg/kg), and DSS + APS (300 mg/kg). The mice in the DSS + APS (100 mg/kg), DSS + APS (200 mg/kg), and DSS + APS (300 mg/kg) groups were intraperitoneally injected with 100, 200, and 300 mg/kg APS once a day, respectively from day 3 to day 10.

Male C57/BL6 mice (eight weeks old, 18-20 g) were purchased from Chengdu Dossy Experimental Animals (China). All the mice were housed in plastic cages with free access to food and water at 25 with a 12 h light/dark cycle. The mice were randomly divided into four groups (n = 6 mice/group): the control group, 5-FU group, 5-FU + TBHQ group, and 5-FU + Fer-1 group. 50 mg/kg body weight 5-FU was intraperitoneally (i.p.) injected into the mice of the 5-FU, 5-FU + TBHQ and 5-FU + Fer-1 group per day for five days to induce intestinal mucositis. Starting on the same day, the mice in the 5-FU + TBHQ and 5-FU + Fer-1 group were treated with TBHQ (10 mg/kg body weight; in DMSO, i.p. injection) or Fer-1 (2.5 mol/kg body weight; in DMSO; i.p. injection) once daily for eight days (days 18). Starting on the same day, the mice of the 5-FU group were treated with equivalent volumes of dimethyl sulfoxide (DMSO) for eight days.

Response regulation | Ferroptosis was shown to be involved in 5-FU-induced intestinal mucositis, and Tertiary butylhydroquinone markedly hampered its activation. Mechanistically, TBHQ activated Nrf2 effectively and selective Nrf2 knockdown significantly reduced the anti-ferroptotic functions of TBHQ in 5-FU-treated HIECs. | ||||
