Mitochondrial dysfunction in kidney injury

Abstract

Background: The body of literature reviewed collectively underscores the critical role of mitochondrial dysfunction in kidney injury, particularly in the contexts of acute kidney injury (AKI) and chronic kidney disease (CKD). The foundational work by (A. Popkov et al., 2019) establishes that mitochondria are not only targets but also sources of uremic toxins, contributing to oxidative stress and subsequent renal cell death. This dual role is pivotal in understanding the mechanisms that lead to kidney damage. Literature Review: Subsequent studies, such as those by (Karina Aranda-Rivera et al., 2021) and (Li et al., 2021), further elaborate on the relationship between mitochondrial redox signaling and oxidative stress, emphasizing how excessive production of reactive oxygen species (ROS) is a hallmark of both AKI and CKD. The high energy demands of renal cells, particularly during acute insults, highlight the importance of mitochondrial integrity in maintaining renal function, as discussed by (Inagi, 2022). The exploration of metabolic derangements associated with mitochondrial dysfunction, as presented by (Inagi, 2022), reveals how impaired mitochondrial biogenesis and an imbalance in mitochondrial dynamics can exacerbate kidney injury. The findings suggest that mitochondrial health is crucial for cellular metabolism and energy production, which is often compromised in kidney diseases. Conclusion: In conclusion, the literature illustrates a multifaceted understanding of mitochondrial dysfunction in kidney injury, emphasizing its implications for both acute and chronic conditions. The ongoing research highlights the potential for mitochondrial-targeted therapies as promising avenues for improving outcomes in renal diseases, thereby paving the way for innovative treatment strategies that address the underlying metabolic derangements associated with these conditions.
