The Nrf2 has been identified as a key molecular player in orchestrating adaptive cellular interactions following a wide spectrum of cellular conditions that could be either extracellular or intracellular. The encoded transcription factor regulates genes, which contain antioxidant response elements (ARE) in their promoters; many of these genes encode proteins involved in response to environmental stress, detoxifying enzymes, metabolic enzymes, injury, and inflammation, which includes the production of free radicals. The association between oxidative stress and inflammation with progression of diabetic nephropathy and cardiomyopathy has been described. The prevention of diabetic nephropathy and cardiomyopathy has become a global concern for those who are working in diabetic care management. Therefore, activation of Nrf2 has the potential to protect against macromolecular damage. Studies have demonstrated the beneficial role of Nrf2 induction in the prevention of DN. Upon exposure of cells to oxidative stress or electrophilic compounds, Nrf2 dissociates from Keap1 and translocates into the nucleus to bind to antioxidant-responsive elements in the genes encoding antioxidant enzymes. Upregulation of these Nrf2-dependent antioxidants promotes detoxification and anti-inflammatory function. Thus, the Nrf2 activators have been suggested for preventing diabetic nephropathy.

Cytogenomic microarray testing allows the detection of submicroscopic genomic rearrangements, commonly denominated copy number variations (CNVs) that are implicated with many neurodevelopmental disorders, dysmorphic features, multiple congenital anomalies, hematological and solid tumors, and complex disorders and traits in both humans and animals. On the other hand, this approach is also widely used for the identification of structural variations that are applied as a biomarker in pharmacogenomics, agriculture, and animal selection and breeding. The chromosomal microarray analysis (CMA) has been applied for over a decade to screen for submicroscopic genomic gains and losses in DNA sample in both diagnostic and functional scenarios. Herein, we present an overview of the fundamental concepts of cytogenomics and its potential application in human genetic diagnosis, agrigenomics, mutagenesis, and pharmacogenomics.
