Unveiling Selected Influences on Chronic Kidney Disease Development and Progression

Area of Science:

• Nephrology
• Molecular Biology
• Pathophysiology

Background:

• Chronic kidney disease (CKD) is a global health concern affecting over 10% of the population.
• Kidney function is vital for homeostasis, regulating blood pressure, pH, and waste elimination.
• Early CKD often lacks specific symptoms, making timely diagnosis challenging.

Purpose of the Study:

• To review the roles of renin-angiotensin-aldosterone system (RAAS) activity, transforming growth factor-β1 (TGF-β1), vascular calcification (VC), uremic toxins, and hypertension in CKD.
• To enhance understanding of the cellular and molecular mechanisms driving CKD.
• To identify potential therapeutic targets for mitigating kidney function decline.

Main Methods:

• Literature review focusing on the molecular and cellular pathways implicated in CKD.
• Analysis of existing research on RAAS, TGF-β1, VC, uremic toxins, and hypertension in the context of kidney disease.
• Synthesis of information to elucidate mechanisms of renal filtration deterioration.

Main Results:

• RAAS overactivity, TGF-β1 signaling, and vascular calcification are key contributors to CKD progression.
• Uremic toxins and hypertension exacerbate kidney damage and impair renal filtration.
• These factors interact to drive the decline in kidney function.

Conclusions:

• A comprehensive understanding of these molecular mechanisms is crucial for advancing CKD treatment.
• Targeting specific pathways like RAAS or TGF-β1 may offer novel therapeutic strategies.
• Further research into these processes can lead to the development of effective CKD medications.
