Klugine (1), isocephaeline (2), and emetine (4) inhibited hypoxia-inducible factor-1 (HIF-1) activation by hypoxia in T47D breast tumor cells (IC(50) values 0.2, 1.1, and 0.11 muM, respectively). Compounds 1, 2, and 4 inhibited both hypoxia- and iron chelator-induced HIF-1 activation by blocking

Emetine, an amoebicidal drug, exerts potent anticancer activity against various solid tumors, however, the underlying molecular mechanism remains unclear. In the present study, the effects of emetine were investigated on various proteins involved in the Wnt/β‑catenin signaling pathway, which has

Exons 3 to 6 in the caspase 9 gene undergo alternative splicing in which the larger caspase 9 splice variant promotes apoptosis, in contrast to the dominant negative anti-apoptotic splice variant, the smaller caspase 9b. In this study, the regulation of the alternative splicing of caspase 9 pre-mRNA

Inhibition of puromycin-induced apoptosis in breast cancer cells by IGF-I occurs simultaneously with increased protein synthesis.

The objective of the following work was to study the apoptosis inducing effect of puromycin in MCF-7 breast cancer cells and compare this effect with cycloheximide and emetine, 2 other inhibitors of protein synthesis. We also wished to investigate if the apoptosis modulating effect of insulin-like

BACKGROUND There is an urgent need to develop new agents for treating metastatic prostate cancer to overcome multiple drug resistance to the current standard targeted cancer therapy. Emetine is a highly cytotoxic natural product protein synthesis inhibitor, which is toxic to all cell types. Its

BACKGROUND Breast cancer (BC) is the second most common cause of death from cancer in women in the United States. As the molecular mechanism of BC has not yet been completely discovered, identification of hub genes and pathways of this disease is of importance for revealing molecular mechanism of

TTFields alone and in combination with chemotherapeutic agents effectively reduce the viability of MDR cell sub-lines that over-express ABC transporters.

BACKGROUND Exposure of cancer cells to chemotherapeutic agents may result in reduced sensitivity to structurally unrelated agents, a phenomenon known as multidrug resistance, MDR. The purpose of this study is to investigate cell growth inhibition of wild type and the corresponding MDR cells by Tumor

Anti-protozoal and anti-bacterial antibiotics that inhibit protein synthesis kill cancer subtypes enriched for stem cell-like properties.

Key players in translational regulation such as ribosomes might represent powerful, but hitherto largely unexplored, targets to eliminate drug-refractory cancer stem cells (CSCs). A recent study by the Lisanti group has documented how puromycin, an old antibiotic derived from Streptomyces alboniger

Inhibitors of protein and RNA synthesis block the cytotoxic effects of non-steroidal antiestrogens.

Non-steroidal antiestrogens such as tamoxifen are known to exert cytotoxic effects against various cell lines in culture. When the antiestrogens are present at sufficiently high concentrations, their cytotoxicity cannot be reversed by estrogens and is demonstrable even with cell lines which lack the
