Phoenixin-14 ameliorates acetic acid-induced ulcerative colitis in rats via antioxidant, anti-inflammatory and anti-apoptotic mechanisms. (PubMed, Peptides)
The control group was treated intraperitoneally with saline, while the colitis groups were treated intraperitoneally with saline or PNX-14 (50 μg/kg/d) or gonadotrophin-releasing hormone (GnRH)-antagonist cetrorelix (CTX; 100µg/kg/d) or CTX and PNX-14 or sulfasalazine as a positive control (100mg/kg/d) instantly and once a day for 3 days following colitis induction. PNX-14, which alleviates macroscopic, histological and biochemical parameters, can be considered as a potential therapeutic agent in ulcerative colitis with its anti-inflammatory, antioxidant and anti-apoptotic actions. Furthermore, despite its effects as an GnRH-antagonist, CTX has also revealed a similar beneficial role as PNX-14 in this ulcerative colitis model.
