Autocrine regulation of mda-7/IL-24 mediates cancer-specific apoptosis.
A noteworthy aspect of melanoma differentiation-associated gene-7/interleukin-24 (mda-7/IL-24) as a cancer therapeutic is its ability to selectively kill cancer cells without harming normal cells. Intracellular MDA-7/IL-24 protein, generated from an adenovirus expressing mda-7/IL-24 (Ad.mda-7), induces cancer-specific apoptosis by inducing an endoplasmic reticulum (ER) stress response. Secreted...
متن کاملNovel mechanism of MDA-7/IL-24 cancer-specific apoptosis through SARI induction.
Subtraction hybridization combined with induction of cancer cell terminal differentiation in human melanoma cells identified melanoma differentiation-associated gene-7/interleukin-24 (mda-7/IL-24) and SARI (suppressor of AP-1, induced by IFN) that display potent antitumor activity. These genes are not constitutively expressed in cancer cells and forced expression of mda-7/IL-24 (Ad.mda-7) or SA...
متن کاملMechanism by which Mcl-1 regulates cancer-specific apoptosis triggered by mda-7/IL-24, an IL-10-related cytokine.
Melanoma differentiation-associated gene-7/interleukin-24 (mda-7/IL-24), a cytokine belonging to the IL-10 family, selectively induces apoptosis in cancer cells without harming normal cells by promoting an endoplasmic reticulum (ER) stress response. The precise molecular mechanism by which the ER stress response culminates in cell death requires further clarification. The present study shows th...
متن کاملMDA-7/IL-24 Induces Bcl-2 Denitrosylation and Ubiquitin-Degradation Involved in Cancer Cell Apoptosis
MDA-7/IL-24 was involved in the specific cancer apoptosis through suppression of Bcl-2 expression, which is a key apoptosis regulatory protein of the mitochondrial death pathway. However, the underlying mechanisms of this regulation are unclear. We report here that tumor-selective replicating adenovirus ZD55-IL-24 leads to Bcl-2 S-denitrosylation and concomitant ubiquitination, which take part ...
متن کاملSulindac enhances adenoviral vector expressing mda-7/IL-24-mediated apoptosis in human lung cancer.
Several studies have shown antitumor activities of the melanoma differentiation-associated gene 7 (mda-7) and the nonsteroidal anti-inflammatory drug sulindac when used as a monotherapies against a wide variety of human cancers. However, the combined effects of mda-7 and sulindac have not previously been tested. Therefore, we tested the antitumor activity of an adenoviral vector expressing mda-...
