Objective(s):Cyclophosphamide (CP) toxicity on testis was hampered by squid ink polysaccharide (SIP) via restoration of antioxidant ability in our previous investigations. This study investigated roles of Nrf2/ARE signal pathway in testis of treated mice. Materials and Methods: Male Kunming mice were employed to undergo treatment with SIP and/or CP. Protein levels of Nrf2, keap-1, histone deac...

background homocysteine is a sulfur-containing amino acid which formed (mainly in the liver) during the metabolism of methionine. prior studies indicated the important role of hyperhomocysteinemia in pathogenesis and progression of alcoholic liver disease, liver steatosis and cirrhosis. one of the most important mechanisms by which homocysteine promote the development of hepatic injury is oxida...

Transcription factor Nrf2 and its negative regulator Keap1 orchestrate a comprehensive cytoprotective response against oxidative, electrophilic, metabolic, inflammatory stress. is drug target, with several small molecules currently in development. Here, we show that the isoquinoline PRL-295 increased thermostability lysates from cells stably expressing fluorescently-tagged Keap1. The of endogen...

We investigated the impact of nuclear factor erythroid 2–related 2 (Nrf2) overexpression in renal proximal tubular cells (RPTCs) on blood glucose, kidney injury, and sodium–glucose cotransporter (Sglt2) expression diabetic Akita Nrf2−/−/Nrf2RPTC transgenic (Tg) mice. Immortalized human RPTCs (HK2) stably transfected with plasmid containing SGLT2 promoter kidneys from patients diabetes were also...

NF-E2 related factor-2 (Nrf2) promotes the transcription of many cytoprotective genes and is a major drug target for prevention of cancer and other diseases. Indeed, the cancer-preventive activities of several well-known chemical agents were shown to depend on Nrf2 activation. It is well known that chemopreventive Nrf2 activators stabilize Nrf2 by blocking its ubiquitination, but previous studi...

The lung is an organ that is sensitive to mutations induced by chemicals in ambient air, and transgenic mice harboring guanine phosphoribosyltransferase (gpt) gene as a target gene are a well-established model system for assessing genotoxicity in vivo. Transcription factor Nrf2 mediates inducible and constitutive expression of cytoprotective enzymes against xenobiotics and mutagens. To address ...

Nrf2 is a key transcription factor that regulates cellular redox and defense responses. However, permanent Nrf2 activation in human lung carcinomas promotes pulmonary malignancy and chemoresistance. We tested the hypothesis that Nrf2 has cell survival properties and lack of Nrf2 suppresses chemically-induced pulmonary neoplasia by treating Nrf2(+/+) and Nrf2(-/-) mice with urethane. Airway infl...

Cancer cells first adapt to the microenvironment and then propagate. Mutations in tumor suppressor genes or oncogenes are frequently found in cancer cells. Comprehensive genomic analyses have identified somatic mutations and other alterations in the KEAP1 or NRF2 genes and in well-known tumor suppressor genes or oncogenes, such as TP53, CDKN2A, PTEN, and PIK3CA, in various types of cancer. Aber...

Nuclear factor erythroid 2-related factor 2 (Nrf2) is one of the transcription factors involved in providing endogenous antioxidants. Black seed oil (BSO), suspected have antioxidant effects that can be used to modulate the expression and levels of Nrf2. The study aims to determine the effect of BSO as adjuvant therapy on levels of Nrf2 to the patients with metabolic syndrome risk. The re...
