Family Short-chain dehydrogenases/reductases (SDR) family
Function
NADPH-dependent reductase with broad substrate specificity. Catalyzes the reduction of a wide variety of carbonyl compounds including quinones, prostaglandins, menadione, plus various xenobiotics. Catalyzes the reduction of the antitumor anthracyclines doxorubicin and daunorubicin to the cardiotoxic compounds doxorubicinol and daunorubicinol. Can convert prostaglandin E to prostaglandin F2-alpha (By similarity). Can bind glutathione, which explains its higher affinity for glutathione- conjugated substrates. Catalyzes the reduction of S-nitrosoglutathione. In addition, participates in the glucocorticoid metabolism by catalyzing the NADPH-dependent cortisol/corticosterone into 20beta-dihydrocortisol (20b-DHF) or 20beta-corticosterone (20b-DHB), which are weak agonists of NR3C1 and NR3C2 in adipose tissue.

In Vivo Model
Male BALB/c nude mice (5 weeks old, weighing 18-20 g) were provided by Jiangsu Jicui Yaokang Biotechnology Co., Ltd. (Nanjing, China). The mice were subcutaneously transplanted with non-targeting shRNA (shcontrol) or CBR1-targeting shRNA (shCBR1)-transfected PANC-1 cells (200 uL, 1 x 107 cells). Tumor volumes and body weights were measured every 4 days (n = 4, each), tumor volume = 0.5 x (a x a x b) (a, smallest diameter; b, largest diameter). The mice were subcutaneously inoculated with PANC-1 cells (200 uL, 1 x 107 cells) in the combination treatment. When the tumor volume reached 80-100 mm3, the mice were treated with chrysin (30 mg/kg/i.P., daily), gemcitabine (20 mg/kg/i.p., once every other day), or in combination for four weeks.

Response regulation Inhibition of CBR1 by chrysin increased cellular ROS levels and led to ROS-dependent autophagy, which resulted in the degradation of ferritin heavy polypeptide 1 (FTH1) and an increase in the intracellular free iron level that participates in ferroptosis in pancreatic cancer (PC) cells. Finally, chrysin enhanced PC sensitivity to gemcitabine by inducing ferroptotic death in vitro and in vivo.?
