Abstract
Lung cancer is one of the most frequent types of cancer in humans and a leading cause of death worldwide. The high mortality rates are correlated with late diagnosis, which leads to high rates of metastasis found in patients. Thus, despite all the improvement in therapeutic approaches, the development of new drugs that control cancer cell migration and metastasis are required. The heptapeptide angiotensin-(1-7) [ang-(1-7)] has demonstrated the ability to control the growth rates of human lung cancer cells in vitro and in vivo, and the elucidation of central elements that control the fine-tuning of cancer cells migration in the presence of the ang-(1-7), will support the development of new therapeutic approaches. Ang-(1-7) is a peptide hormone of the renin-angiotensin system (RAS) and this study investigates the modulatory effect of the heptapeptide on the expression pattern of microRNAs (miRNAs) in lung tumor cells, to elucidate mechanistic concerns about the effect of the peptide in the control of tumor migratory processes. Our primary aim was to compare the miRNA profiling between treated and untreated-heptapeptide cells to characterize the relevant molecule that modulates cellular migration rates. The analyses selected twenty one miRNAs, which are differentially expressed between the groups; however, statistical analyses indicated miRNA-149-3p as a relevant molecule. Once functional analyses were performed, we demonstrated that miRNA-149-3p plays a role in the cellular migration processes. This information could be useful for future investigations on drug development.

Cellular and molecular studies of the effects of a selective COX-2 inhibitor celecoxib in the cardiac cell line H9c2 and their correlation with death mechanisms. ACTA ACUST UNITED AC 2013; 47:50-9.

Abstract
Cardiovascular disease is one of the leading causes of death worldwide, and evidence
indicates a correlation between the inflammatory process and cardiac dysfunction.
Selective inhibitors of cyclooxygenase-2 (COX-2) enzyme are not recommended for
long-term use because of potentially severe side effects to the heart. Considering
this and the frequent prescribing of commercial celecoxib, the present study analyzed
cellular and molecular effects of 1 and 10 µM celecoxib in a cell culture model.
After a 24-h incubation, celecoxib reduced cell viability in a dose-dependent manner
as also demonstrated in MTT assays. Furthermore, reverse transcription-polymerase
chain reaction analysis showed that the drug modulated the expression level of genes
related to death pathways, and Western blot analyses demonstrated a modulatory effect
of the drug on COX-2 protein levels in cardiac cells. In addition, the results
demonstrated a downregulation of prostaglandin E2 production by the cardiac cells
incubated with celecoxib, in a dose-specific manner. These results are consistent
with the decrease in cell viability and the presence of necrotic processes shown by
Fourier transform infrared analysis, suggesting a direct correlation of prostanoids
in cellular homeostasis and survival.
