Down-regulation of TNF-alpha receptors by conophylline in human T-cell leukemia cells.[Pubmed:14532979]
Int J Oncol. 2003 Nov;23(5):1373-9.
In the course of our screening for tumor necrosis factor-alpha (TNF-alpha) function inhibitors, Conophylline, a vinca alkaloid isolated from the plant Ervatamia microphylla, was found to inhibit TNF-alpha-induced NF-kappaB activation. We studied the effect of Conophylline on TNF-alpha-induced NF-kappaB and JNK activations in human T-cell leukemia Jurkat cells. Conophylline inhibited both of these TNF-alpha-induced activations. It also inhibited phosphorylation and degradation of I-kappaB-alpha. Moreover, a receptor binding assay using [125I]-TNF-alpha showed that this inhibitory effect was due to a decrease in the binding of TNF-alpha to the cells. Scatchard analysis of the binding data indicated that Conophylline induced only a small change in the affinity of the receptors but a significant change in the receptor number. FACS analysis showed that Conophylline reduced the expression of CD120a/TNFR1, the high-affinity receptor for TNF-alpha, on the cell surface. On the other hand, Conophylline did not affect the kinetics of internalization and degradation of TNF-alpha/receptor complexes or the half-life of TNF-alpha binding sites. These results indicate that Conophylline down-regulates the expression of the TNF-alpha receptors on the cell surface.
Conophylline suppresses hepatic stellate cells and attenuates thioacetamide-induced liver fibrosis in rats.[Pubmed:24119135]
Liver Int. 2014 Aug;34(7):1057-67.
BACKGROUND & AIMS: Conophylline (CnP) is a vinca alkaloid purified from a tropical plant and inhibits activation of pancreatic stellate cells. We investigated the effect of CnP on hepatic stellate cells (HSC) in vitro. We also examined whether CnP attenuates hepatic fibrosis in vivo. METHOD: We examined the effect of CnP on the expression of alpha-smooth muscle actin (alpha-SMA) and collagen-1, DNA synthesis and apoptosis in rat HSC and Lx-2 cells. We also examined the effect of CnP on hepatic fibrosis induced by thioacetamide (TAA). RESULTS: In rat HSC and Lx-2 cells, CnP reduced the expression of alpha-SMA and collagen-1. CnP inhibited DNA synthesis induced by serum. CnP also promoted activation of caspase-3 and induced apoptosis as assessed by DNA ladder formation and TUNEL assay. In contrast, CnP did not induce apoptosis in AML12 cells. We then examined the effect of CnP on TAA-induced cirrhosis. In TAA-treated rats, the surface of the liver was irregular and multiple nodules were observed. Histologically, formation of pseudolobules surrounded by massive fibrous tissues was observed. When CnP was administered together with TAA, the surface of the liver was smooth and liver fibrosis was markedly inhibited. Collagen content was significantly reduced in CnP-treated liver. CONCLUSION: Conophylline suppresses HSC and induces apoptosis in vitro. CnP also attenuates formation of the liver fibrosis induced by TAA in vivo.
Conophylline: a novel differentiation inducer for pancreatic beta cells.[Pubmed:16337165]
Int J Biochem Cell Biol. 2006;38(5-6):923-30.
Reduction of the beta cell mass is critical in the pathogenesis of diabetes mellitus. The discovery of agents, which induce differentiation of pancreatic progenitors to beta cells, would be useful to develop a new therapeutic approach to treat diabetes. To identify a new agent to stimulate differentiation of pancreatic progenitor cells to beta cells, we screened various compounds using pancreatic AR42J cells, a model of pancreatic progenitor cells. Among various compounds and extracts tested, we found that Conophylline, a vinca alkaloid extracted from leaves of a tropical plant Ervatamia microphylla, was effective in converting AR42J into endocrine cells. Conophylline reproduces the differentiation-inducing activity of activin A. Unlike activin A, however, Conophylline does not induce apoptosis. To induce differentiation of AR42J cells, Conophylline increases the expression of neurogenin-3 by activating p38 mitogen-activated protein kinase. Conophylline also induces differentiation in cultured pancreatic progenitor cells obtained from fetal and neonatal rats. More importantly, Conophylline is effective in reversing hyperglycemia in neonatal streptozotocin-treated rats, and both the insulin content and the beta cell mass are increased by Conophylline. Histologically, Conophylline increases the numbers of ductal cells positive for pancreatic-duodenal-homeobox protein-1 and islet-like cell clusters. Conophylline and related compounds are useful in inducing differentiation of pancreatic beta cells both in vivo and in vitro.
Conophylline suppresses pancreatic stellate cells and improves islet fibrosis in Goto-Kakizaki rats.[Pubmed:22202163]
Endocrinology. 2012 Feb;153(2):621-30.
Activin A is a differentiation factor for beta-cells and is effective to promote beta-cell neogenesis. Activin A is also an autocrine activator of pancreatic stellate cells, which play a critical role in fibrogenesis of the pancreas. Conophylline (CnP) is a natural compound, which reproduces the effect of activin on beta-cell differentiation and promotes beta-cell neogenesis when administered in vivo. However, its effect on stellate cells is not known. We therefore investigated the effect of CnP on stellate cells both in vitro and in vivo. Unlike activin A, CnP inhibited activation of cultured stellate cells and reduced the production of collagen. We then analyzed the involvement of stellate cells in islet fibrosis in Goto-Kakizaki (GK) rats, a model of type 2 diabetes mellitus. In pancreatic sections obtained from 6-wk-old GK rats, CD68-positive macrophages and glial fibrillary acidic protein- and alpha-smooth muscle actin-positive stellate cells infiltrated into islets. Later, the number of macrophages was increased, and the alpha-smooth muscle actin staining of stellate cells became stronger, indicating the involvement of stellate cells in islet fibrosis in GK rats. When CnP was administered orally for 4 wk, starting from 6 wk of age, invasion of stellate cells and macrophages was markedly reduced and islet fibrosis was significantly improved. The insulin content was twice as high in CnP-treated rats. These results indicate that CnP exerts antifibrotic actions both in vitro and in vivo and improves islet fibrosis in Goto-Kakizaki rats.
Promotion of beta-cell differentiation by conophylline in fetal and neonatal rat pancreas.[Pubmed:15448089]
Diabetes. 2004 Oct;53(10):2596-602.
Conophylline is a vinca alkaloid extracted from the tropical plant Ervatamia microphylla and has been shown to induce differentiation of pancreatic AR42J cells. In the present study, we investigated the effect of Conophylline on the differentiation of pancreatic precursor cells. In the rat pancreatic rudiment in organ culture, Conophylline inhibited the formation of cystic structure and increased the number of insulin-positive cells. Conophylline also markedly increased the expression of mRNA for insulin and the number of pancreatic duodenal homeobox-1-positive cells. These effects of Conophylline were similar to those of activin A. We also examined the effect of Conophylline on neonatal rats treated with streptozotocin, a model of type 2 diabetes. Treatment with Conophylline significantly reduced the plasma glucose concentration and improved glucose tolerance in response to glucose loading. The insulin content and the beta-cell mass at 2 months were significantly increased by Conophylline. The number of islet-like cell clusters and pancreatic duodenal homeobox-1-positive ductal cells was greater in Conophylline-treated rats. These results suggest that Conophylline induces differentiation of pancreatic precursor cells and increases the formation of beta-cells.
