(Submitter supplied) The NRF2 transcription factor is a key regulator of the cellular antioxidant response, and pharmacological NRF2 activation is a promising strategy for the prevention of age-related diseases. Here we show, however, that genetic activation of Nrf2 in skin fibroblasts leads to the production of a matrisome, which is similar to aged skin and characterized by reduced synthesis and deposition of selected matrix proteins, including the major skin collagens. more...

(Submitter supplied) Nrf2 is a key regulator of the cellular antioxidant defense system, and pharmacological Nrf2 activation is a promising strategy for cancer prevention. Here we discovered a novel role of Nrf2 as a regulator of the matrisome. Activation of Nrf2 in fibroblasts induced early onset of cellular senescence. Mechanistically, this resulted from Nrf2-mediated transcription of matrix and matrix-remodeling genes. more...

(Submitter supplied) Long wavelength Ultraviolet (UVA-1) radiation causes oxidative stress that leads to the formation of noxious substances within the skin. As a defensive mechanism skin cells produce detoxifying enzymes and antioxidants when they detect modified molecules. We have recently shown that UVA-1 irradiation oxidizes the abundant membrane phospholipid 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (PAPC), which then induced the synthesis of the stress response protein heme oxygenase 1 (HO-1) in dermal fibroblasts. more...

(Submitter supplied) In this study, the miRNA expression of human vascular endothelial cells from tissue-derived cells and cultured cells were profiled using miRNA sequencing. The data analysis revealed a striking switch in endothelial miRNA profile as the cells adapted from tissue to cell culture environment and the overall miRNA expression decreased significantly in cultured endothelial cells compared to tissue-derived endothelial cells. more...

(Submitter supplied) NF-E2-related factor 2 (Nrf2), a transcription factor activated by oxidative stress, induces phase II conjugating or antioxidant enzymes. In the present study, we examined the effect of Nrf2 knockout (Nrf2 KO) on the kidney injury induced by cisplatin using cDNA microarray analyses. A transcriptomic approach enabled us to extract gene clusters which show significantly different mRNA expression patterns between wild type (WT) and Nrf2 KO mice. more...
