Role of Nrf2 in the pathogenesis of respiratory diseases

Publication date: Available online 6 November 2019Source: Respiratory InvestigationAuthor(s): Kenji Mizumura, Shuichiro Maruoka, Tetsuo Shimizu, Yasuhiro GonAbstractNuclear factor erythroid 2-related factor (Nrf)2 is a transcription factor that integrates cellular stress signals by directing various transcriptional programs. As an evolutionarily conserved intracellular defense mechanism, Nrf2 and its endogenous inhibitor Kelch-like ECH-associated protein (Keap)1 inhibit oxidative stress in the lung, which is the internal organ that is continuously exposed to the environment. Oxidative stress is implicated in the pathogenesis of various lung diseases including asthma, acute lung injury, chronic obstructive pulmonary disease (COPD), and interstitial lung disease (ILD). Thus, Nrf2 is considered as a potential therapeutic target in lung diseases owing to its antioxidant effect. Nrf2 also plays a complex role in lung cancer, acting as a tumor suppressor and promoter; recent studies have revealed the tumor-promoting effects of Nrf2 in tumors that have undergone malignant transformation. Lung cancer-associated mutations in Keap1 disrupt Keap1–Nrf2 complex formation, resulting in the ubiquitination and degradation of Keap1, and the constitutive activation of Nrf2. In lung cancer cells, persistently high nuclear Nrf2 levels induce the expression of genes that contribute to metabolic reprogramming, and stimulate cell proliferation. In this review, we outlined the major functions ...

CONCLUSIONS: AI technologies are growing their role in health care; but, up to now, their "real-life" implementation remains limited. However, in the near future, the potential of AI-driven era could change the clinical practice in Urology, improving overall patient outcomes. PMID: 31833725 [PubMed - as supplied by publisher]

CONCLUSIONS: Our data show high adherence and persistence rates in men on ADT. The overall survival in the super-elderly is not influenced by persistence and/or adherence but rather by co-prescriptions. PMID: 31833723 [PubMed - as supplied by publisher]

CONCLUSIONS: ORP, ePLND and seminal vesicle invasion are independent predictors of the risk of hospital readmission over the long term at a large single tertiary referral center. When surgery is chosen as a primary treatment of PCA, patients should be informed of the risk of hospital readmission and related risk factors. Assessing seminal vesicle invasion by preoperative clinical staging identifies locally advanced disease, which is associated with an increased risk of hospital readmission.

The subjective assessment of the included parameters and the unreliability for off-clamp procedures limited their reproducibility; their role in predicting functional and oncologic outcomes has never...

CONCLUSIONS: Long-term treatment with 5- ARIs might reduce the risk of bladder tumour recurrence, extension of lesions and increase the recurrence-free survival rate. A long-term, randomized prospective study could definitively assess the possible role of these drugs. PMID: 31833718 [PubMed - as supplied by publisher]

CONCLUSIONSĖ Follow-up schedules for stage I seminoma exposes patients to potential risks of radiation- induced tumors, emotional distress and represent a significant burden for the healthcare system. The current series suggests that a better risk adapted patient-tailored follow-up program is needed in order to avoid unnecessary investigations. PMID: 31833335 [PubMed - as supplied by publisher]

Conclusion: The vast majority of patients gained a clinically important improvement. Symptom burden may be more important for selecting patients for PR than diagnosis.
