Mitochondrial dysfunction in resveratrol-induced apoptosis in QGY-7701 cells

J. P. Li, Ma, Q., Chen, C. M., Li, J. P., Ma, Q., Chen, C. M., Li, J. P., Ma, Q., and Chen, C. M., “Mitochondrial dysfunction in resveratrol-induced apoptosis in QGY-7701 cells”, vol. 15, p. -, 2016.

This study aims to evaluate the cytotoxicity of resveratrol on QGY-7701 cells via a cell viability assay, and determine the cytological alterations and damages that result. Resveratrol was found to inhibit QGY-7701 cell growth and decrease their viability in a remarkably dose-dependent manner. Resveratrol exposure also induced an increase in Caspase-3 activity and a decrease in Bcl-2, which caused an increase in membrane permeability, and the opening of mitochondrial permeability transition pores and mitochondrial depolarization.

Resveratrol could reverse the expression of SIRT1 and MMP-1 in vitro

J. W. Wu, Wang, J. J., Chen, J. B., Huang, Y. L., Wang, H., Liu, G. H., Li, L. F., Kang, M., Wang, X. G., and Cai, H. H., “Resveratrol could reverse the expression of SIRT1 and MMP-1 in vitro”, vol. 14, pp. 12386-12393, 2015.

Intervertebral disc degeneration is the main cause of lumbago disease, in which the extracellular matrix structure and moisture in the nucleus pulposus is lost continuously. In this study, we aimed to detect differential expression of silence mating type information regulation 2 homolog 1 (SIRT1) and matrix metalloproteinase-1 (MMP-1) in human intervertebral disc nucleus pulposus cells and to explore the effects of SIRT1 and MMP-1 on the development of the intervertebral disc degeneration.

Inhibition of human chronic myelogenous leukemia K562 cell growth following combination treatment with resveratrol and imatinib mesylate

X. J. Wang and Li, Y. H., “Inhibition of human chronic myelogenous leukemia K562 cell growth following combination treatment with resveratrol and imatinib mesylate”, vol. 14, pp. 6413-6418, 2015.

To investigate the effect of treatment with resveratrol combined with imatinib mesylate on human chronic myelogenous leukemia K562 cell growth inhibition and apoptosis, in vitro cultured human chronic myelogenous leukemia K562 cells were incubated with different concentrations of resveratrol and imatinib mesylate when the cells were in the logarithmic phase. Next, the cell growth inhibition was evaluated using the MTT assay and cellular morphology observation. Apoptosis was determined using Annexin V fluorescein isothiocyanate/propidium iodide double staining.

Resveratrol, an activator of SIRT1, upregulates AMPK and improves cardiac function in heart failure

X. S. Gu, Wang, Z. B., Ye, Z., Lei, J. P., Li, L., Su, D. F., and Zheng, X., “Resveratrol, an activator of SIRT1, upregulates AMPK and improves cardiac function in heart failure”, vol. 13, pp. 323-335, 2014.

Reduced AMP-activated protein kinase (AMPK) expression has been shown to play a significant role in the cardiac dysfunction in heart failure. This study was designed to examine the effect of resveratrol, a potent activator of silent information regulator (SIRT1), on cardiac function and AMPK expression in heart failure. Adult male rat left anterior descending arteries were ligated, and they were fed with either a regular diet or a diet enriched with resveratrol.

The effects of resveratrol on cyclooxygenase-1 and -2, nuclear factor kappa beta, matrix metalloproteinase-9, and sirtuin 1 mRNA expression in hearts of streptozotocin-induced diabetic rats

A. S. Yar, Menevse, S., and Alp, E., “The effects of resveratrol on cyclooxygenase-1 and -2, nuclear factor kappa beta, matrix metalloproteinase-9, and sirtuin 1 mRNA expression in hearts of streptozotocin-induced diabetic rats”, vol. 10, pp. 2962-2975, 2011.

Resveratrol (RSV) has a beneficial role in the prevention of diabetes and alleviates some diabetic complications, such as cardiomyopathy. We investigated cyclooxygenase-1 (COX-1), COX-2, nuclear factor κB (NF-κB), matrix metalloproteinase-9 (MMP-9), and sirtuin 1 (SIRT1) mRNA expression levels in heart tissue after RSV treatment in streptozotocin (STZ)-induced diabetic rats. After induction of chronic diabetes with STZ, 10 mg RSV/kg per day was administered to DM and DM+RSV groups for four weeks.
