Abstract
With recent advances in neonatal intensive care, preterm infants are surviving into adulthood. Nonetheless, epidemiological data on the health status of these preterm infants have begun to reveal a worrying theme; prematurity and the supplemental oxygen therapy these infants receive after birth appear to be risk factors for kidney disease in adulthood, affecting their quality of life. As the incidence of chronic kidney disease and the survival time of preterm infants both increase, the management of the hyperoxia-induced renal disease is becoming increasingly relevant to neonatologists. The mechanism of this increased risk is currently unknown, but prematurity itself and hyperoxia exposure after birth may predispose to disease by altering the normal trajectory of kidney maturation. This article reviews altered renal reactivity due to hyperoxia, the possible mechanisms of renal injury due to hyperoxia, and the role of resveratrol in renal injury. KEY POINTS: · Premature infants commonly receive supplementary oxygen.. · Hyperoxia can cause kidney damage via signal pathways.. · We should reduce the occurrence of late sequelae..

Abstract
OBJECTIVE To explore whether protein kinase B (serine/threonrine kinase, AKT)/forkhead box protein O3a (foxo3a) pathway mediates the protective mechanism of resveratrol (RSV) on renal interstitial fibrosis (RIF) and oxidative stress. METHODS Sprague-Dawley (SD) rats were grouped into Sham group, unilateral ureteral obstruction (UUO) group and UUO + RSV group. HE staining was used to test the pathological damage of RIF intervened by RSV, biochemical analyzer was used to measure serum renal injury indexes (creatinine, Cr, blood urea nitrogen, Bun), and enzyme-linked immunosorbent assay (ELISA) was used to detect oxidative stress indexes (malondialdehyde, MDA; glutathione, GSH; superoxide dismutase, SOD). AKT/FoxO3a signaling pathway markers and renal interstitial indexes were measured by western blot analysis. RESULTS Compared with Sham group, HE staining in UUO group showed significant RIF pathological damage; Cr and Bun indexes were increased, and AKT/FoxO3a signal pathway was activated, as indicated by increased p-AKT/AKT and p-FoxO3a/FoxO3a; TGF-β1 and α-SMA protein levels in fibrosis indexes were increased, while E-cadherin decreased; MDA was increased, GSH and SOD were decreased in oxidative stress indexes, while those in UUO + RSV group were improved. CONCLUSION AKT/foxo3a signaling pathway mediates the protective mechanism of RSV on RIF and oxidative stress in UUO rats, and RSV can improve RIF and oxidative stress in UUO rats by inhibiting AKT/foxo3a signaling pathway.

Abstract
Emerging evidence indicates that HSP70 represents a key mechanism in the pathophysiology of β-cell dysfunction, insulin resistance, and various diabetic complications, including micro- and macro-vascular alterations, as well as impaired hemostasis. Hyperglycemia, a hallmark of both types of diabetes, increases the circulating levels of HSP70 (eHSP70), but there is still divergence about whether diabetes up- or down-regulates the intracellular fraction of this protein (iHSP70). Here, we consider that iHSP70 levels reduce in diabetic arterial structures and that the vascular system is in direct contact with all other systems in the body suggesting that a systemic response might also be happening for iHSP70, which is characterized by decreased levels of HSP70 in the vasculature. Furthermore, although many pathways have been proposed to explain HSP70's functions in diabetes, and organs/tissues/cells-specific variations occur, the membrane-bound receptor of the innate immune system, Toll-like receptor 4, and its downstream signal transduction pathways appear to be a constant, not only when we explore the actions of eHSP70, but also when we assess the contributions of iHSP70. In this review, we focus on discussing the multiple roles of HSP70 across organs/tissues/cells affected by hyperglycemia to further explore the possibility of targeting this protein with pharmacological and non-pharmacological approaches in the context of diabetes.

Biochim Biophys Acta Mol Basis Dis 2022; 1868:166365.

Abstract
As a deacetylase, SIRT1 plays essential roles in various physiological events, from development to lifespan regulation. SIRT1 has been shown neuroprotective effects in neurodegeneration disorders such as Parkinson's disease (PD). However, the underlying molecular mechanisms are still not well understood. Here, we generated transgenic mice with increased expression of Sirt1 in the brain and examined the potential roles of SIRT1 in PD. Our data showed that SIRT1 repressed proinflammatory cytokine expression both in microglia and astrocytes. In MPTP induced PD model mice, lower levels of microglia and astrocyte activation were observed in SIRT1 transgenic mice. Moreover, the tyrosine hydroxylase (TH) loss in the substantia nigra pars compacta (SNpc) and striatum induced by MPTP was also attenuated by SIRT1. As a consequence, the behavioral defects induced by MPTP were largely prevented in SIRT1 transgenic mice. Mechanistically, SIRT1 interacts with heat shock 70 kDa protein 4 (HSPA4) and deacetylates it at 305, 351 and 605 lysine residues. This deacetylation modification induces the nuclear translocation of HSPA4 and thus to repress proinflammatory cytokine expression. On the contrary, mutated HSPA4, in which 305/351/605 lysine residues were replaced with arginine, was mainly localized in the cytoplasm and losses its repression on proinflammatory cytokine expression. Taken together, our data indicate that SIRT1 plays beneficial roles in PD model mice, which is likely due to, at least in part, its anti-inflammation activity in glial cells by deacetylating HSPA4. Furthermore, HSPA4 might be a druggable target for developing novel agents for treating neuroinflammation associated disorders such as PD.

Abstract
Background Although ionizing radiation (IR) has been of immense value to human life due to its involvement in several fields, it doesn’t eliminate that exposure to IR results in an array of biological consequences, including oxidative stress, inflammation, and death. Thus, this study aimed to explore the curative effect of trans-Resveratrol (t-Res) on hepatic and renal injury in a rat model exposed to single and fractionated doses of γ-rays. Methods Rats exposed to a single dose of IR (6 Gy, as an acute effect) or a fractionated dose of IR (2 Gy/time/3 days, day after day; to imitate a chronic impact) were treated with t-Res. Then, the radio-protective effect of t-Res was investigated via biochemical and histological estimations in the liver and kidney of rats in the different groups. Results The data displayed a significant amelioration in biochemical and histological indices in the liver and kidney of rats exposed to IR doses and treated with t-Res. Particularly, t-Res reduced the oxidative stress milieu through decreasing HIF-1α, ROS, and MDA levels associated with increased CAT activity and Nrf-2 gene expression. Also, t-Res improved the inflammatory status via a decrease in TNF-α, NF-κB, SOCS-3, and HSP-70 genes expression linked with elevations in SIRT-1 and P53 genes expression. Conclusion It could be concluded that t-Res had hepatoprotective and renoprotective effects against the deleterious consequences of γ-rays exposure due to its antioxidant and anti-inflammatory properties.

Abstract
Introduction In animal models, it can be difficult to confirm therapeutic effects due to technical inconsistencies and other reasons. Although renal biopsy is widely used in clinical diagnosis, it is rarely used in animal experimental models, especially in mice, because the problems of surgery-induced renal injury and bleeding have not been solved. Methods We developed an easy-to-use method of renal biopsy in mice and evaluated whether 3 consecutive renal biopsies can be performed in the same kidney in a standardized manner. This method was verified using 2 mouse models, a healthy mouse model and a unilateral ureteral obstruction (UUO) mouse model, and evaluated based on renal function and histological changes. Results There were no perioperative complications in any of the model mice. There was no significant difference in serum Cr, 24-h urine protein, or kidney/body weight ratio between the biopsy and control groups. Each biopsy sample contained sufficient renal tissue. The damage to the operated tissue was limited to the tissue near the biopsy site. Compared with renal tissues in the corresponding control group, the renal tissues obtained from the 3 biopsies (healthy model days 0, 4, and 7 and UUO model days 3, 7, and 10) and the remnant renal tissues after the biopsy showed no significant difference in the glomerular sclerosis index, degree of renal tubular damage, inflammatory response and renal fibrosis in these 2 models. Conclusions Our new standardized method of renal biopsy in mice is a safe and cost-saving approach that allows repeated renal biopsies and ensures minimal trauma and sufficient sample size to quality in experimental disease models.
