Rubia cordifolia L. Dichloromethane Extract Ameliorates Contrast-Induced Acute Kidney Injury by Activating Autophagy via the LC3B/p62 Axis
Xiaoying Sun, Kangxu He, Guanzhong Chen, Xiaoda Yang, Xinhui Pan, Kai Liao
TL;DR
This study shows that an extract from Rubia cordifolia L. protects against kidney injury caused by contrast agents, possibly by boosting autophagy.
Contribution
The study identifies Rubia cordifolia L. dichloromethane extract as a potential therapeutic for contrast-induced acute kidney injury via autophagy activation.
Findings
RCDE high-dose group significantly reduced serum SCr and BUN levels in CIAKI rats.
RCDE attenuated renal histopathological damage and modulated oxidative stress markers.
RCDE modulated autophagy-related proteins, including downregulating p62 and the LC3B-II/LC3B-I ratio.
Abstract
Contrast-induced acute kidney injury (CIAKI) has emerged as the third most prevalent etiology of clinically acquired acute kidney injury, with a lack of specific preventive and therapeutic strategies. Rubia Cordifolia L. (madder root), a medicinal herb with a long-standing history and extensive clinical application, exhibits multiple pharmacological activities. This study aimed to clarify the renal protective effect of Rubia cordifolia L. dichloromethane extract (RCDE) on CIAKI modeling rats and investigate potential anti-apoptotic and autophagy-inducing effects molecular mechanisms. In this study, RCDE constituents were identified by UPLC-Q-TOF-MS. A CIAKI rat model was established to evaluate the nephroprotective effect of RCDE. The results showed that RCDE high-dose group significantly decreased serum SCr and BUN levels, attenuated renal histopathological damage, and modulated…
