Diabetic Kidney Diseases (DKD) is a very serious complication of diabetes. There is recent steep rise in the prevalence of metabolic syndrome and DKD worldwide. Factors responsible for intraglomerular hypertension include activation of various vasoactive systems, polyol pathway, oxidative stress, inflammation and protein kinase C. Sodium-Dependent Glucose Co-Transporter (SGLT-2) inhibitors, DPP-IV (Dipeptidyl peptidase-4) inhibitors are being develop to manage the hyperglycemia and oxidative stress induced inflammatory cascade. Herbal drugs have gained increasing popularity; are complex mixtures of polyphenols and phytochemicals from any raw or processed part of a plant, including leaves. Herbal drugs in this modern era are preferred due to its lesser side effects. Various preparations are presently used for ameliorating the effect of DKD. Since, medicinal plants have been reported to affect various metabolic receptors, enzymes and signaling cascade. Above book chapter explains the involvement of different phytochemicals in biological pathway associated with the kidney damage.

AbstractActivation of the apoptotic pathway is a major cause of progressive loss of function in chronic diseases such as neurodegenerative and diabetic kidney diseases. There is an unmet need for an anti-apoptotic drug that acts in the early stage of the apoptotic process. The multifunctional protein Na+,K+-ATPase has, in addition to its role as a transporter, a signaling function that is activated by its ligand, the cardiotonic steroid ouabain. Several lines of evidence suggest that sub-saturating concentrations of ouabain protect against apoptosis of renal epithelial cells, a common complication and major cause of death in diabetic patients. Here, we induced apoptosis in primary rat renal epithelial cells by exposing them to an elevated glucose concentration (20 mM) and visualized the early steps in the apoptotic process using super-resolution microscopy. Treatment with 10 nM ouabain interfered with the onset of the apoptotic process by inhibiting the activation of the BH3-only protein Bad and its translocation to mitochondria. This occurred before the pro-apoptotic protein Bax had been recruited to mitochondria. Two ouabain regulated and Akt activating Ca2+/calmodulin-dependent kinases were found to play an essential role in the ouabain anti-apoptotic effect. Our results set the stage for further exploration of ouabain as an anti-apoptotic drug in diabetic kidney disease as well as in other chronic diseases associated with excessive apoptosis.

Mitochondria are critical organelles that play a key role in cellular metabolism, survival, and homeostasis. Mitochondrial dysfunction has been implicated in the pathogenesis of diabetic kidney disease. The function of mitochondria is critically regulated by several mitochondrial protein kinases, including the phosphatase and tensin homolog (PTEN)-induced kinase 1 (PINK1). The focus of PINK1 research has been centered on neuronal diseases. Recent studies have revealed a close link between PINK1 and many other diseases including kidney diseases. This review will provide a concise summary of PINK1 and its regulation of mitochondrial function in health and disease. The physiological role of PINK1 in the major cells involved in diabetic kidney disease including proximal tubular cells and podocytes will also be summarized. Collectively, these studies suggested that targeting PINK1 may offer a promising alternative for the treatment of diabetic kidney disease.
