Mcl-1: A Gateway to TRAIL Sensitization: Figure 1.

Mcl-1: a gateway to TRAIL sensitization.

The proapoptotic cytokine tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is being evaluated presently as a selective anticancer agent, but its limited effects against cancer cell lines has raised some concerns about its ultimate clinical utility. Here, we review recent findings that cancer cell sensitivity to TRAIL is greatly increased when the Bcl-2 family protein Mcl-1 is dow...

Ouabain downregulates Mcl-1 and sensitizes lung cancer cells to TRAIL-induced apoptosis.

Resistance to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a prerequisite for cancer progression, and TRAIL resistance is prevalent in lung cancer. Ouabain, a recently identified human hormone, has shown therapeutic promise by potentiating the apoptotic response of metastatic lung cancer cells to TRAIL. Nontoxic concentrations of ouabain are shown to increase caspase-3 act...

Metformin enhances TRAIL-induced apoptosis by Mcl-1 degradation via Mule in colorectal cancer cells

Metformin is an anti-diabetic drug with a promising anti-cancer potential. In this study, we show that subtoxic doses of metformin effectively sensitize human colorectal cancer (CRC) cells to tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), which induces apoptosis. Metformin alone did not induce apoptosis, but significantly potentiated TRAIL-induced apoptosis in CRC cells....

Chrysin overcomes TRAIL resistance of cancer cells through Mcl-1 downregulation by inhibiting STAT3 phosphorylation.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively kills various types of cancer cells without harming normal cells, but TRAIL resistance has been frequently observed in cancer cells. Propolis (bee glue) is a material collected from various plants by honeybees and is a rich source of bioactive compounds, including the natural flavonoid chrysin, which possesses multiple ...
