Abstract

Non-steroidal anti-inflammatory drugs (NSAIDs) have anti-proliferative effects and induce apoptosis in colon and other cancers. In the present study, we report that mefenamic acid (MEF), a member of NSAIDs, has an inhibitory effect on a proliferation of liver cancer cells. We used Chang and Huh-7 cells as human liver cancer cells. MEF-treated Huh-7 and Chang cells displayed apoptotic morphological changes and the portion of cells in sub G1 was increased 3-fold and 6-fold, respectively, at a 200 microM concentration. We also show an MEF-enhanced binding of annexin V to cells and an increased activity of caspase-3 to cleave PARP-1 and caspase itself. The inhibitor of caspase-3 blocked PARP-1 cleavage activity and protected against MEF-induced apoptotic cell death. These results indicate that MEF induces apoptosis in human liver cancer cells.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.
