Abstract
Development and progression of many kidney diseases are substantially influenced by aberrant protein acetylation modifications of gene expression crucial for kidney functions. Histone deacetylase (HDAC) expression alterations are detected from renal samples of patients and animal models of various kidney diseases, and the administrations of HDAC inhibitors display impressive renal protective effects in vitro and in vivo. However, when the expression alterations of multiple HDACs occur, not all the HDACs causally affect the disease onset or progression. Identification of a single HDAC as a disease-causing factor will allow subtype-targeted intervention with less side effect. HDAC3 is a unique HDAC with distinct structural and subcellular distribution features and co-repressor dependency. HDAC3 is required for kidney development and its aberrations actively participate in many pathological processes, such as cancer, cardiovascular diseases, diabetes, and neurodegenerative disorders, and contribute significantly to the pathogenesis of kidney diseases. This review will discuss the recent studies that investigate the critical roles of HDAC3 aberrations in kidney development, renal aging, renal cell carcinoma, renal fibrosis, chronic kidney disease, polycystic kidney disease, glomerular podocyte injury, and diabetic nephropathy. These studies reveal the distinct characters of HDAC3 aberrations that act on different molecules/signaling pathways under various renal pathological conditions, which might shed lights into the epigenetic mechanisms of renal diseases and the potentially therapeutic strategies.

Abstract
Histone deacetylases (HDACs) are part of the epigenetic machinery that regulates transcriptional processes. The current paradigm is that HDACs silence gene expression via regulation of histone protein lysine deacetylation, or by forming corepressor complexes with transcription factors. However, HDACs are more than just nuclear proteins, and they can interact and deacetylate a growing number of nonhistone proteins to regulate cellular function. Cancer-field studies have shown that deranged HDAC activity results in uncontrolled proliferation, inflammation, and fibrosis; all pathologies that also may occur in kidney disease. Over the past decade, studies have emerged suggesting that HDAC inhibitors may prevent and potentially treat various models of acute kidney injury. This review focuses on the physiology of kidney HDACs and highlights the recent advances using HDAC inhibitors to potentially treat kidney disease patients.

Abstract
Background and purpose Stromal-derived factor (SDF)-1, a chemokine recruiting leucocytes and stem cells, plays an essential role in tissue regeneration. In a previous study, we have unexpectedly found that the expression of this chemokine declines following kidney ischemia reperfusion (IR). To explain this observation, a mathematical model was constructed which proposed histone deacetylase (HDAC) as the main driver of SDF-1 down-regulation. To experimentally verify this prediction, the effect of valproic acid (VPA), a potent HDAC inhibitor, on the kinetics of kidney SDF-1 expression was here assessed. Experimental approach Adult mice were subjected to IR or sham operation and received VPA or vehicle. Next, SDF-1 expression as well as tissue repair indices were measured in a time course manner. Findings / Results The transcriptional expressions of Sdf-1 alpha, beta, and gamma isoforms were noisy in the sham groups but the fluctuations disappeared following IR where a continuous declining trend was observed. VPA induced the over-expression of gamma, but not alpha and beta mRNA in IR mice which was accompanied with protein upregulation. Remarkably, VPA deteriorated kidney injury. Conclusion and implications HDAC inhibition restores SDF-1 down-regulation following kidney IR. The present study is a classic example of the potential of computational modeling for the prediction of biomedical phenomena.

Abstract
Aims/Hypothesis: Transforming growth factor-beta (TGF-β1) plays an important regulatory role in the progression of chronic kidney failure. Further, damage to kidney glomerular mesangial cells is central to the progression of diabetic nephropathy. The aim of this study was to explore the genetic associations between mRNA, microRNA, and epigenetics in mesangial cells in response to TGF-β1. Methods: The regulatory effects of TGF-β1 on mesangial cells were investigated at different molecular levels by treating mesangial cells with TGF-β1 for 3 days followed by genome-wide miRNA, RNA, DNA methylation, and H3K27me3 expression profiling using next generation sequencing (NGS). Results: Our results provide the first comprehensive, computationally integrated report of RNA-Seq, miRNA-Seq, and epigenomic analyses across all genetic variations, confirming the occurrence of DNA methylation and H3K27me3 in response to TGF-β1. Our findings show that the expression of KLF7 and Gja4 are involved in TGF-β1 regulated DNA methylation. Our data also provide evidence of the association between epigenetic changes and the expression of genes closely related to TGF-β1 regulation. Conclusion: This study has advanced our current knowledge of mechanisms that contribute to the expression of TGF-β1-regulated genes involved in the pathogenesis of kidney disease. The molecular underpinnings of TGF-β1 stimulation of kidney cells was determined, thereby providing a robust platform for further target exploration.

Abstract
Understanding epigenetic mechanisms is crucial to our comprehension of gene regulation in development and disease. In the past decades, different studies have shown the role of epigenetic modifications and modifiers in renal disease, especially during its progression towards chronic and end-stage renal disease. Thus, the identification of genetic variation associated with chronic kidney disease has resulted in better clinical management of patients. Despite the importance of these findings, the translation of genotype-phenotype data into gene-based medicine in chronic kidney disease populations still lacks faithful cellular or animal models that recapitulate the key aspects of the human kidney. The latest advances in the field of stem cells have shown that it is possible to emulate kidney development and function with organoids derived from human pluripotent stem cells. These have successfully recapitulated not only kidney differentiation, but also the specific phenotypical traits related to kidney function. The combination of this methodology with CRISPR/Cas9 genome editing has already helped researchers to model different genetic kidney disorders. Nowadays, CRISPR/Cas9-based approaches also allow epigenetic modifications, and thus represent an unprecedented tool for the screening of genetic variants, epigenetic modifications or even changes in chromatin structure that are altered in renal disease. In this Review, we discuss these technical advances in kidney modeling, and offer an overview of the role of epigenetic regulation in kidney development and disease.

Abstract
Tubulointerstitial fibrosis is a common feature of kidney disease. Histone deacetylase (HDAC) inhibitors have been reported to attenuate renal fibrosis progression. Here, we investigated the effect of CG200745, a novel HDAC inhibitor, on renal fibrosis development in a mouse model of unilateral ureteral obstruction (UUO). To examine the effects of CG200745 on renal fibrosis in UUO, C57BL/6 J male mice were divided into three groups: control, UUO, and CG200745 (30 mg/kg/day)-treated UUO groups. CG 200745 was administered through drinking water for 1 week. Human proximal tubular epithelial (HK-2) cells were also treated with CG200745 (10 µM) with or without TGF-β (2 ng/mL). Seven days after UUO, plasma creatinine did not differ among the groups. However, plasma neutrophil gelatinase-associated lipocalin (NGAL) levels were markedly increased in the UUO group, which were attenuated by CG200745 treatment. UUO kidneys developed marked fibrosis as indicated by collagen deposition and increased α-smooth muscle actin (SMA) and fibronectin expression. CG200745 treatment attenuated these fibrotic responses and suppressed UUO-induced production of transforming growth factor-beta1 (TGF-β) and phosphorylation of Smad-2/3. CG200745 treatment also attenuated UUO-induced inflammation as indicated by the expression of inflammatory markers. Furthermore, CG200745 attenuated phosphorylation of p38 mitogen-activated protein kinase in UUO kidneys. In HK-2 cells, TGF-β induced the expression of α-SMA and fibronectin, which were attenuated by CG200745 cotreatment. These results demonstrate that CG200745, a novel HDAC inhibitor, has a renoprotective effect by suppressing renal fibrosis and inflammation in a UUO mouse model.

Abstract
Diabetes mellitus (DM) is a risk factor for abnormal heart development, but the molecular mechanism remains obscure. Histone deacetylase 11 (HDAC11), the most recently identified histone deacetylase, is the sole member of class IV HDACs. However, its role in diabetic cardiac injury is still poorly understood. In the present study, we attempted to explore the effects of HDAC11 on fructose (Fru)-induced cardiac injury using the wild type (HDAC11+/+) and knockout (HDAC11-/-) mice. The results indicated that HDAC11 was significantly expressed in human and mouse diabetic heart failure (DHF) hearts. HDAC11-/- reduced the body weight, inguinal fat-pad mass, and elevated blood pressure in Fru-fed mice. Compared to HDAC11+/+/Fru group, cardiac function was significantly improved in HDAC11-/-/Fru mice. HDAC11-/-/Fru mice exhibited reduced cardiac triacylglycerol (TG), total cholesterol (TC) and free fatty acid (FFA) levels, along with decreased mRNA levels of lipid synthesis-, lipid storage- and lipid oxidation-associated genes. In addition, HDAC11-/- attenuated apoptosis, oxidative stress and inflammation in the heart of Fru-fed mice, as evidenced by the reduced cleavage of Caspase-3, nicotinamide adenine dinucleotide phosphate (NADPH), and xanthine oxidase (XOD) activity, enhanced superoxide dismutase (SOD) activity, as well as the decreased interleukin 1β (IL-1β) and tumor necrosis factor-α (TNF-α) levels, which was accompanied with down-regulated p-NF-κB. The results above were verified in Fru-treated primary cardiomyocytes isolated from HDAC11+/+ or HDAC11-/- mice. Intriguingly, suppressing the expressions of anti-oxidants using zinc protoporphyrin (ZnPP) or siNrf-2 siRNA markedly abolished the results that HDAC11 suppression-induced reduction of apoptosis, reactive oxygen species (ROS) production, inflammation, as well as the improvement of dyslipidemia in Fru-incubated primary cardiomyocytes. Thus, ROS production was responsible for HDAC11-modulated diabetic heart injury. These findings suggested that suppressing HDAC11 has therapeutic potential for treating diabetes mellitus-associated cardiac injury.

Abstract
p53 is best identified as a tumor suppressor for its transcriptional control of genes involved in cell cycle progression and apoptosis. Beyond its irrefutable involvement in restraining unchecked cell proliferation, research over the past several years has indicated a requirement for p53 function in sustaining normal development. Here I summarize the role of p53 in embryonic development, with a focus on knowledge gained from p53 loss and overexpression during kidney development. In contrast to its classical role in suppressing proliferative pathways, p53 positively regulates nephron progenitor cell (NPC) renewal. Emerging evidence suggests p53 may control cell fate decisions by preserving energy metabolism homeostasis of progenitors in the nephrogenic niche. Maintaining a critical level of p53 function appears to be a prerequisite for optimal nephron endowment. Defining the molecular networks targeted by p53 in the NPC may well provide new targets not only for regenerative medicine but also for cancer treatment.

Abstract
All-trans retinoic acid (atRA), which is mainly generated endogenously via two steps of oxidation from vitamin A (retinol), plays an indispensible role in the development of the kidney and many other organs. Enzymes that catalyze the oxidation of retinol to generate atRA, including aldehyde dehydrogenase 1 family (ALDH1)A1, ALDH1A2 and ALDH1A3, exhibit complex expression patterns at different stages of renal development. However, molecular triggers that control these differential expression levels are poorly understood. In this study, we provide in vitro evidence to demonstrate that Wilms' tumor 1 (WT1) negatively regulates the expression of the atRA synthetic enzymes, ALDH1A1, ALDH1A2 and ALDH1A3, in the 293 cell line, leading to significant blockage of atRA production. Furthermore, we demonstrate that the suppression of ALDH1A1 by WT1 can be markedly attenuated by histone deacetylase inhibitors (HDACis). Taken together, we provide evidence to indicate that WT1 and HDACs are strong regulators of endogenous retinoic acid synthetic enzymes in 293 cells, indicating that they may be involved in the regulation of atRA synthesis.

TGF-β induces miR-30d down-regulation and podocyte injury through Smad2/3 and HDAC3-associated transcriptional repression. J Mol Med (Berl) 2015; 94:291-300.

Abstract
The microRNA-30 family plays important roles in maintaining kidney homeostasis. Patients with focal segmental glomerulosclerosis (FSGS) have reduced miR-30 levels in glomerulus. TGF-β represses miR-30s in kidney podocytes, which leads to cytoskeleton damage and podocyte apoptosis. In this study, we investigated the mechanism by which TGF-β represses miR-30d in vitro. The human miR-30d promoter contains multiple copies of Smad binding element-like sequences. A fragment of 150 base pairs close to the transcription start site was negatively regulated by TGF-β to a similar extent as the 1.8 kb promoter, which was blocked by histone-deacetylase inhibition. TGF-β specifically enhanced HDAC3 expression. Knockdown of HDAC3 by shRNA or a selective inhibitor RGFP966 significantly relieved the repression of miR-30d mRNA and the promoter transcription. TGF-β promoted HDAC3 association with Smad2/3 and NCoR and caused their accumulation at the putative Smad binding site on the miR-30d promoter, which was prohibited by TSA or RGFP966. Furthermore, TSA or RGFP966 treatment reversed TGF-β-induced up-regulation of miR-30d targets Notch1 and p53 and alleviated the podocyte cytoskeleton damage and apoptosis. Taken together, these findings pinpoint that TGF-β represses miR-30d through a Smad2/3-HDAC3-NCoR repression complex and provide novel insights into a potential target for the treatment of podocyte injury-associated glomerulopathies. Key message: MiR-30d promoter is negatively regulated by TGF-β. TGF-β down-regulates miR-30 through Smad signaling pathway. HDAC3 and NCoR are recruited by Smad2/3 to mediate miR-30d repression by TGF-β. HDAC3 acts as a critical player in TGF-β-induced miR-30d repression and podocyte injuries.

Abstract
The present study aimed to examine the effect of the histone deacetylase inhibitor, vorinostat (SAHA), on renal function in a calcium oxalate crystal mouse model, and to investigate the mechanism underlying the renoprotective effect of SAHA. Calcium oxalate crystal formation was induced in 8 week-old male C57BL/6 mice by administering 100 mg/kg glyoxylate for 7 days. A total of 24 male C57BL/6 mice were randomly divided into a control group and the following experimental groups: 50 mg/kg normal saline + 100 mg/kg glyoxylate; 50 mg/kg dimethyl sulfoxide (DMSO) + 100 mg/kg glyoxylate; and 50 mg/kg SAHA + 100 mg/kg glyoxylate. The mice in each of the experimental groups were injected with the saline, DMSO or SAHA into their abdominal cavities 6 h prior to the glyoxylate injection. The mice were sacrificed after 7 days, following which blood and urine samples were collected. The kidneys were harvested to analyze the levels of calcium concentrations and the levels of malondialdehyde (MDA), superoxide dismutase and glutathione reductase. Immunohistochemical staining and semi-quantitative analyses were performed to detect the expression levels of osteopontin (OPN) and CD44. Renal tubular cell apoptosis was detectedusing a TUNEL assay. The concentrations of calcium and malondialdehyde were significantly decreased in the SAHA group, and calcium oxalate crystals in the kidney tissue and the expression levels of OPN and CD44 in the SAHA group were lower, compared with the other experimental groups. SAHA significantly reduced the urinary excretion of KIM-1 and renal tubular cell apoptosis. In conclusion, SAHA reduced calcium oxalate crystal deposition and protected against kidney injury.

Abstract
Histone deacetylases (HDACs) induce deacetylation of both histone and non-histone proteins and play a critical role in the modulation of physiological and pathological gene expression. Pharmacological inhibition of HDAC has been reported to attenuate progression of renal fibrogenesis in obstructed kidney and reduce cyst formation in polycystic kidney disease. HDAC inhibitors (HDACis) are also able to ameliorate renal lesions in diabetes nephropathy, lupus nephritis, aristolochic acid nephropathy, and transplant nephropathy. The beneficial effects of HDACis are associated with their anti-fibrosis, anti-inflammation, and immunosuppressant effects. In this review, we summarize recent advances on the treatment of various chronic kidney diseases with HDACis in pre-clinical models.

Abstract
The discovery that histone deacetylase inhibitors (HDACis) can attenuate acute kidney injury (AKI)-mediated damage and reduce fibrosis in kidney disease models has opened the possibility of utilizing HDACis as therapeutics for renal injury. Studies to date have made it abundantly clear that HDACi treatment results in a plethora of molecular changes, which are not always linked to histone acetylation, and that there is an essential need to understand the specific target(s) of any HDACi of interest. New lines of investigation are beginning to delve more deeply into target identification of specific HDACis and to address the relative toxicity of different HDACi classes. This review will focus on the utilization of HDACis during kidney organogenesis, injury, and disease, as well as on the development of these compounds as therapeutics.
