Caffeine inhibits hepatitis C virus replication in vitro

Abstract Hepatitis C is considered the major cause of cirrhosis and hepatocellular carcinoma. Conventional treatment is not effective against some hepatitis C virus (HCV) genotypes; therefore, new treatments are needed. Coffee and, more recently, caffeine, have been found to have a beneficial effect in several disorders of the liver, including those manifesting abnormal liver biochemistry, cirrhosis and hepatocellular carcinoma. Caffeine acts directly by delaying fibrosis, thereby improving the function of liver cellular pathways and interfering with pathways used by the HCV replication cycle. In the current study, the direct relationship between caffeine and viral replication was evaluated. The Huh-7.5 cell line was used for transient infections with FL-J6/JFH-50 C19Rluc2AUbi and to establish a cell line stably expressing SGR-Feo JFH- 1. Caffeine efficiently inhibited HCV replication in a dosedependent manner at non-cytotoxic concentrations and demonstrated an IC50 value of 0.7263 mM after 48 h of incubation. These data demonstrate that caffeine may be an important new agent for anti-HCV therapies due to its efficient inhibition of HCV replication at non-toxic concentrations.

Avaliação dos efeitos de aloe-emodin em células uroteliais imortalizadas e neoplásicas cultivadas in vitro

Aloe vera (Aloe barbadensis Miller), popularly known in Brazil as babosa, has a long history of use as medicinal plant for different therapeutic purposes. The components of the plant extract are present in various products of human use, mainly for nutritional and cosmetics purposes. However, some studies suggest that this extract might also have carcinogenic activity. The aloe vera extract is a complex mixture of bioactive compounds. The study of isolated compounds may contribute to elucidate contradictory results about the effects related to the consumption of the plant, as well as their mechanisms of action. One of the most important compound from Aloe vera is aloe-emodin, which is a secondary metabolite generated in the intestinal tract. Putative antimicrobial and antitumor effects were previously attributed to aloe-emodin. Although the exposure of urothelial cells to aloe-emodin was already reported in the literature, only one study showed its effects on urothelial cells, suggesting that aloe-emodin inhibits the viability of T24 cancer cells due to apoptosis induction. Since there is no sufficient information about the effects of aloe-emodin on urothelial cells, and low efficiency in the treatment of bladder cancer currently, the present study aims to evaluate the hypothesis that the treatment with aloe-emodin could impact the behavior of other urothelial cell lines in vitro. Therefore, the in vitro IC50 exposure of aloe-emodin to human immortalized neoplastic urothelial cells will be determinated in order to verify possible differences in the behavior of urothelial cells in vitro treated with aloe-emodin in comparison with untreated cells. Furthermore, differences between cell lines will be also evaluated
