In Vitro Conophylline (100 ng/ml; 48 hours) reproduces differentiationinducing activity but not apoptosis-inducing activity of activin[1]. Conophylline (100 ng/ml; 72 hours) exhibits the differentiation-inducing activity in AR42J cells and converts these cells to endocrine cells[1]. Conophylline increases the expression of neurogenin-3 by activating p38 mitogen-activated protein kinase to induce differentiation of AR42J cells[1]. Conophylline reduces the expression of α-SMA and collagen-1 in rat HSC and Lx-2 cells[2]. Conophylline inhibits DNA synthesis induced by serum[2]. Conophylline also promots activation of caspase-3 and induces apoptosis in Lx-2 Cells[2]. Apoptosis Analysis[2] Cell Line: Lx-2 Cells Concentration: 12 hours Incubation Time: 0.1 μg/ml Result: Induced apoptosis Western Blot Analysis[2] Cell Line: Lx-2 cells Concentration: 0.1 μg/ml Incubation Time: 15 minutes, 30 minutes, 60 minutes, 120 minutes Result: Increased phospho-JNK.
In Vivo Conophylline (0.9 mg/kg; p.o.; daily; for 12 weeks) attenuates formation of the liver fibrosis induced by TAA in vivo[2]. Animal Model: Sprague-Dawley rats (70-80 g)[2] Dosage: 0.9 mg/kg Administration: Oral administration; daily; for 12 weeks Result: Attenuated formation of the liver fibrosis induced by TAA.
