Abstract
Acute kidney injury (AKI) is one of the most challenging clinical problems in kidney disease due to serious complications and high mortality rate, which can lead to acute lung injury (ALI) through inflammatory reactions and oxidative stress. Adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway has been reported to be involved in the development of renal ischemia-reperfusion through autophagy and it remains unclear whether AMPK/mTOR pathway has an effect on the AKI-induced ALI. In this study, we aimed to investigate the effects of autophagy-related AMPK/mTOR signaling pathway on inflammatory factors and oxidative stress in an AKI-induced ALI model. The 48 male Sprague-Dawley rats were divided into four groups randomly: (i) sham, (ii) ischemia/reperfusion injury (IRI), (iii) IRI + rapamycin (RA), and (iv) IRI + 3-methyladenine (3-MA). Unilateral flank incisions were made and right kidneys were excised. The left kidney was subjected to 60 min of ischemia followed by 12, 24, 48, and 72 h of reperfusion. The levels of Scr, blood urea nitrogen (BUN), Wet/Dry ratio, indexes of inflammation, and oxidative stress were assayed. Histological examinations were performed. The protein expression of AMPK, mTOR, LC3-II/LC3-I ratio, and Beclin-1, ULK1 was evaluated by western blotting and immunohistochemistry. Compared to the rats from the sham group, IRI rats showed significantly pulmonary damage after AKI with increased Scr, BUN, Wet/Dry ratio, indexes of inflammation, and oxidative stress. The expression of AMPK, LC3-II/LC3-I ratio, Beclin-1, and ULK1 and were increased, while p62 and mTOR were decreased. In addition, RA treatment significantly attenuated lung injury by promoting autophagy through the activation of the AMPK/mTOR pathway, and 3-MA treatment exhibited adverse effects inversely. Therefore, the activation of the AMPK/mTOR pathway after renal IRI induction could significantly attenuate kidney injury and following AKI-induced ALI by inducing autophagy, which alienates inflammation, oxidative stress, and apoptosis.

Abstract
Cisplatin (CP) is a broad-spectrum antineoplastic agent, used to treat many different types of malignancies due to its high efficacy and low cost. However, its use is largely limited by acute kidney injury (AKI), which, if left untreated, may progress to cause irreversible chronic renal dysfunction. Despite substantial research, the exact mechanisms of CP-induced AKI are still so far unclear and effective therapies are lacking and desperately needed. In recent years, necroptosis, a novel subtype of regulated necrosis, and autophagy, a form of homeostatic housekeeping mechanism have witnessed a burgeoning interest owing to their potential to regulate and alleviate CP-induced AKI. In this review, we elucidate in detail the molecular mechanisms and potential roles of both autophagy and necroptosis in CP-induced AKI. We also explore the potential of targeting these pathways to overcome CP-induced AKI according to recent advances.

Abstract
AbstractAcute kidney injury (AKI) is in high prevalence in the world. However, the therapeutic strategies for AKI are still in mystery. Studies have shown to improve autophagy and lysosomal function could inhibit AKI. But their modulators need to be explored in detail. Annexin A2 (ANXA2) is a phospholipid-binding protein involving in organelle membrane integrity function, suggesting its important role in autophagy and lysosome homeostasis. It implicates ANXA2 potentially protects against AKI. However, this has not been elucidated. Herein, we found that ANXA2 is increased in renal tubules in cisplatin-induced AKI mice. Ectopic expression of ANXA2 improved lysosomal functions and enhanced autophagic flux, further protecting against renal tubular cell apoptosis and kidney injury. Conversely, knockdown of ANXA2 inhibited lysosomal function and autophagy, which aggravated the progression of AKI. Transcriptome sequencing revealed β-catenin signaling is highly responsible for this process. In vitro, we found ANXA2 induced β-catenin activation, further triggering T-cell factor-4 (TCF4)-induced transcription factor EB (TFEB). Furthermore, TFEB promoted lysosome biogenesis to enhance autophagic flux, resulting in the alleviation of AKI. Our new findings underline ANXA2 is a new therapeutic potential for AKI through modulating autophagy and lysosomal function. The underlying mechanism is associated with its inductive effects on β-catenin/TFEB pathway.

Abstract
Cancer treatment-induced toxicities may restrict maximal effective dosing for treatment and cancer survivors' quality of life. It is critical to develop novel strategies that mitigate treatment-induced toxicity without affecting the efficacy of anti-cancer therapies. Rapamycin is a macrolide with anti-cancer properties, but its clinical application has been hindered, partly by unfavorable bioavailability, pharmacokinetics, and side effects. As a result, significant efforts have been undertaken to develop a variety of nano-delivery systems for the effective and safe administration of rapamycin. While the efficacy of nanostructures carrying rapamycin has been studied intensively, the pharmacokinetics, biodistribution, and safety remain to be investigated. In this study, we demonstrate the potential for rapamycin perfluorocarbon (PFC) nanoparticles to mitigate cisplatin-induced acute kidney injury with a single preventative dose. Evaluations of pharmacokinetics and biodistribution suggest that the PFC nanoparticle delivery system improves rapamycin pharmacokinetics. The safety of rapamycin PFC nanoparticles was shown both in vitro and in vivo. After a single dose, no disturbance was observed in blood tests or cardiac functional evaluations. Repeated dosing of rapamycin PFC nanoparticles did not affect overall spleen T cell proliferation and responses to stimulation, although it significantly decreased the number of Foxp3+CD4+ T cells and NK1.1+ cells were observed.
