Abstract

Abstract Background Some plants had been used in the treatment of cancer and one of these has attracted scientific interest, theEuphorbia tirucalli (E. tirucalli ), used in the treatment of asthma, ulcers, warts has active components with activities scientifically proven as antimutagenic, anti-inflammatory and anticancer. Methods We evaluate the influence of the antitumoral fraction of theE. tirucalli latex in the larynx squamous cell carcinoma (Hep-2), on the morphology, cell proliferation and gene expression. The Hep-2 cells were cultivated in complete medium (MEM 10 %) and treated withE. tirucalli latex for 1, 3, 5 and 7 days. After statistically analyzing the proliferation of the tested cells, the cells were cultivated again for RNA extraction and the Rapid Subtractive Hybridization (RaSH ) technique was used to identify genes with altered expression. The genes found using theRaSH technique were analyzed by Gene Ontology (GO) using Ingenuity Systems. Results The five genes found to have differential expression were validated by real-time quantitative PCR. Though treatment withE. tirucalli latex did not change the cell morphology in comparison to control samples, but the cell growth was significantly decreased. TheRaSH showed change in the expression of some genes, includingANXA1, TCEA1, NGFRAP1, ITPR1 andCD55, which are associated with inflammatory response, transcriptional regulation, apoptosis, calcium ion transport regulation and complement system, respectively. TheE. tirucalli latex treatment down-regulatedITPR1 and up-regulatedANXA1 andCD55 genes, and was validated by real-time quantitative PCR. Conclusions The data indicate the involvement ofE. tirucalli latex in the altered expression of genes involved in tumorigenic processes, which could potentially be applied as a therapeutic indicator of larynx cancer.
