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...

Pancreatic cancer is an aggressive disease with limited therapeutic options. Melanoma differentiation-associated gene-7/interleukin-24 (mda-7/IL-24), a potent antitumor cytokine, shows cancer-specific toxicity in a vast array of human cancers, inducing endoplasmic reticulum stress and apoptosis, toxic autophagy, an antitumor immune response, an antiangiogenic effect, and a significant "bystande...

AIM To reveal any correlation between cigarette smoke and malondialdehyde (MDA) values in the saliva fluid of subjects who are active smokers or nonsmoking subjects who are exposed to cigarette smoke in their environments. MATERIALS AND METHODS Saliva samples were taken from 3 groups: a control group (group 1), a group inhaling smoke passively (group 2), and a test group (group 3) smoking 20 ...

Background Malondialdehyde (MDA), glyoxal (GO), and methylglyoxal (MGO) levels increase in atherosclerosis and diabetes patients. Recent reports demonstrate that GO and MGO cause vascular endothelial barrier dysfunction whereas no evidence is available for MDA. Methods To compare the effects of MDA, GO, or MGO on endothelial permeability, we used human EA.hy926 endothelial cells as a standard...

The maintained expression of transcription factors throughout the development of mesodiencephalic dopaminergic (mDA) neurons suggests multiple roles at various stages in development. Two members of the forkhead/winged helix transcription factor family, Foxa1 and Foxa2, have been recently shown to have an important influence in the early development of mDA neurons. Here we present data demonstra...

Bone metastasis is one of the most severe cancer complications. To analyze the mechanism of bone metastasis, we established highly invasive cell lines from the human breast cancer cell line MDA-MB-231 using an in vitro sequential selection system. The cell lines, MDA-231-S10 and MDA-231-S5, were more invasive and more motile than the parental cell line. Moreover, MDA-231-S10 metastasized to bon...

Epithelial-mesenchymal transition (EMT) is one of the decisive steps regulating cancer invasion and metastasis. However, the molecular mechanisms underlying this transition require further clarification. MDA-9/syntenin (SDCBP) expression is elevated in breast cancer patient samples as well as cultured breast cancer cells. Silencing expression of MDA-9 in mesenchymal metastatic breast cancer cel...

BACKGROUND AND OBJECTIVE Oxidative stress plays an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD). In this longitudinal study changes in the level of malondialdehyde (MDA), an end product of polyunsaturated fatty acid peroxidation, were investigated in the airways of patients with acute exacerbation of COPD (AECOPD). METHODS Levels of MDA were measured in s...

Malondialdehyde (MDA) is one of the most commonly reported biomarkers of lipid peroxidation in clinical studies. The reaction of thiobarbituric acid (TBA) with MDA to yield a pink chromogen attributable to an MDA-TBA₂ adduct is a common assay approach with products being quantified by ultraviolet-Vis assay as nonspecific TBA-reactive substances (TBARS) or chromatographically as MDA. The specifi...

to investigate the effect of salinity stress on membrane stability index, membrane lipid peroxidation, catalase activity and protein content of fenugreek (trigonellafoenum) an experiment with five levels of short-term salinity stress (0, 50, 100, 150 and 200 mm) was carried out at the laboratory of agriculture faculty of shahid bahonar university of kerman, iran. the treatments were arranged ba...
