Sodium-glucose co-transporters and diabetic nephropathy: Is there a link with toll-like receptors?

The incidence of diabetes mellitus (DM) has increased alarmingly over the last decades. Despite taking measures aimed at controlling hyperglycaemia and blood pressure, the rate of end-stage renal disease (ESRD) is continually growing. Upon increased amounts of advanced glycation end products (AGEs) and their correspondent receptors (RAGEs), AGE-RAGE axis is over-activated in DM, being the first step in the initiation and propagation of inflammatory cascades.

The impact of dyslipidemia and oxidative stress on vasoactive mediators in patients with renal dysfunction.

Hyperlipidemia and oxidative stress are indispensable features of chronic kidney disease (CKD) that favor the development of atherogenic plaques and cardiovascular disease (CVD). A number of vasoactive mediators including proprotein convertase subtilisin-kexin type 9 (PCSK9), endothelin-1, nitric oxide, and angiotensin II have fundamental roles in the pathophysiology of atherosclerotic events; moreover, their levels are affected by dyslipidemia and oxidative stress due to renal dysfunction. Therefore, therapeutic measures aimed at correcting dyslipidemia and alleviating oxidative stress could potentially protect against CVD in CKD patients.

Major fundamental factors hindering immune system in defense against tumor cells: The link between insufficiency of innate immune responses, metabolism, and neurotransmitters with effector immune cells disability.

Despite the major progresses in comprehending the mechanisms of tumor immunosurveillance and the role of innate and adaptive immune systems in recent years, there are still a number of obstacles hindering successful and effective immunotherapy of cancer. Such obstacles have been mainly attributed to the ability of tumors in creating a tolerant microenvironment and exploiting a plethora of immunosuppressive factors that counter effective immune responses against tumor cells. Here we represent a new insight into probable links between immune system disability with metabolism and chronic psychological stress which is beyond the other strategies recruited by tumors to thwart tumor immunosurveillance.

Interplay between microRNAs and Wnt, transforming growth factor-β, and bone morphogenic protein signaling pathways promote osteoblastic differentiation of mesenchymal stem cells.

Osteoblasts are terminally differentiated cells with mesenchymal origins, known to possess pivotal roles in sustaining bone microstructure and homeostasis. These cells are implicated in the pathophysiology of various bone disorders, especially osteoporosis. Over the last few decades, strategies to impede bone resorption, principally by bisphosphonates, have been mainstay of treatment of osteoporosis; however, in recent years more attention has been drawn on bone-forming approaches for managing osteoporosis.

Introduction: Nontraditional risk factors for cardiovascular disease (CVD), including mineral disorder, high fibroblast growth factor 23 (FGF23), low klotho, and low soluble TWEAK could predict the incipient risk of CVD in chronic kidney disease (CKD). The present study evaluates the effect of sevelamer on soluble tumor necrosis factor-like weak inducer of apoptosis (TWEAK), and klotho levels in adenine-induced CKD rats.

Methods And Materials: Normal control rats without sevelamer were compared with 3 groups of adenine-induced CKD rats, including CKD rats without sevelamer, CKD rats treated with 3% sevelamer, and rats receiving adenine and 3% sevelamer concurrently.

Background: High serum phosphate and fibroblast growth factor-23 (FGF-23) levels are well-recognized independent risk factors of mortality and morbidity in patients with chronic kidney diseases (CKDs). Sevelamer, as a phosphate chelating agent, reduces serum phosphate and FGF-23 levels produced by bone osteocytes. This study aimed to determine the best dose at which sevelamer could successfully reduce serum phosphate and FGF-23 levels in rat models of adenine-induced CKD.

AGE-RAGE axis blockade in diabetic nephropathy: Current status and future directions.

Diabetic nephropathy is one of the most frequent micro-vascular complications both in type 1 and type 2 diabetic patients and is the leading cause of end-stage renal disease worldwide. Although disparate mechanisms give rise to the development of diabetic nephropathy, prevailing evidence accentuates that hyperglycemia-associated generation of advanced glycation end products (AGEs) plays a central role in the disease pathophysiology. Engagement of the receptor for AGE (RAGE) with its ligands provokes oxidative stress and chronic inflammation in renal tissues, ending up with losses in kidney function.
