Nrf2 and TGF-β1 both affect tumorigenesis in a dual fashion, either by preventing carcinogen induced carcinogenesis and suppressing tumor growth, respectively, or by conferring cytoprotection and invasiveness to tumor cells during malignant transformation. Given the involvement of Nrf2 and TGF-β1 in the adaptation of epithelial cells to persistent inflammatory stress, e.g. of the pancreatic duc...
Hypoxia leads to reactive oxygen species (ROS) imbalance, which is proposed to associate with drug resistance and oncogenesis. Inhibition of enzymes of antioxidant balancing system in tumor cells was shown to reduce chemoresistance under hypoxia. However, the underlying mechanism remains unknown. The key regulator of antioxidant balancing system is nuclear factor erythroid 2-related factor 2 (N...
Sustained activation of the stress-regulated transcription factor NRF2 (NFE2L2) is a prominent feature of many types of cancer, implying that mutations driving NRF2 may be important to tumor progression. In hereditary type 2 papillary renal cell carcinoma (PRCC2, also known as hereditary leiomyomatosis and renal cell cancer), NRF2 activation is a direct consequence of the accumulation of intrac...
Eriodictyol-7-O-glucoside, a flavonoid isolated from Dracocephalum rupestre, is among the most potent free radical scavenger. In the present study, we identified eriodictyol-7-O-glucoside as a novel nuclear factor E2-related factor 2 (Nrf2) activator using a high-throughput cellular screening method. This compound activated Nrf2 signaling pathway and was able to stabilize Nrf2 by delaying Nrf2 ...
Nrf2 is the key transcription factor regulating the antioxidant response. When exposed to oxidative stress, Nrf2 translocates to cell nucleus and forms heterodimer with small Maf proteins (sMaf). Nrf2/sMaf heterodimer binds specifically to a cis-acting enhancer called antioxidant response element and initiates transcription of a battery of antioxidant and detoxification genes. Nrf2 possesses a ...
Currently, the sole treatment option for patients with heart failure is transplantation. The battle of prolonging graft survival and modulating innate and adaptive immune responses is still being waged in the clinic and in research labs. The transcription factor Nrf2 controls major cell survival pathways and is central to moderating inflammation and immune responses. In this study the effect of...
Forebrain neurons have weak intrinsic antioxidant defences compared with astrocytes, but the molecular basis and purpose of this is poorly understood. We show that early in mouse cortical neuronal development in vitro and in vivo, expression of the master-regulator of antioxidant genes, transcription factor NF-E2-related-factor-2 (Nrf2), is repressed by epigenetic inactivation of its promoter. ...
The Nuclear factor erythroid2-related factor2 (Nrf2), a master regulator of redox homoeostasis, is a key transcription factor regulating a wide array of genes for antioxidant and detoxification enzymes. It protects organs from various kinds of toxic insults. On the other hand, activation of Nrf2 is also correlated with cancer progression and chemoresistance. Downregulation of Nrf2 activity has ...
Non-small cell lung cancer (NSCLC) causes considerable mortality in the world. Owing to molecular biological progress, treatments in adenocarcinoma have evolved revolutionarily while those in squamous lung cancer remain unsatisfied. Recent studies revealed high-frequency alteration of Kelch-like ECH-associated protein 1/nuclear factor erythroid 2-like factor 2 (Keap1/Nrf2) pathway within squamo...
Nuclear factor erythroid-2-related factor 2 (Nrf2) appears to exert either a protective or detrimental effect on the heart; however, the underlying mechanism remains poorly understood. Herein, we uncovered a novel mechanism for turning off the Nrf2-mediated cardioprotection and switching on Nrf2-mediated cardiac dysfunction. In a murine model of pressure overload-induced cardiac remodeling and ...
