Zymosan A 是一种来源于酿酒酵母(Saccharomyces cerevisiae)的多糖类TLR2激动剂,可通过TLR2和Wnt信号通路上调ASCL2,促进辐射损伤后肠道干细胞(ISCs)再生,具有显著的辐射防护作用,可预防和缓解IR诱导的肠道损伤,同时能诱导免疫反应、炎症、厌食和体温升高,常用于构建腹膜炎模型。
α-Cortolone, a metabolite of the glucocorticoid cortisol (hydrocortisone), is produced through the action of 20α-hydroxysteroid dehydrogenase (20α-HSD) via a tetrahydrocortisone (THE) intermediate. Studies indicate that urinary levels of α-cortolone are reduced in patients experiencing severe anorexia nervosa and postmenopausal women diagnosed with endometrial adenocarcinoma, in comparison to postmenopausal women without the condition.
