Identification of Novel Key Molecular Signatures in the Pathogenesis of Experimental Diabetic Kidney Disease. Front Endocrinol (Lausanne) 2022; 13:843721. [PMID: 35432190 PMCID: PMC9005898 DOI: 10.3389/fendo.2022.843721] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2021] [Accepted: 02/28/2022] [Indexed: 11/15/2022] Open
Abstract
Diabetic kidney disease (DKD) is a long-term major microvascular complication of uncontrolled hyperglycemia and one of the leading causes of end-stage renal disease (ESDR). The pathogenesis of DKD has not been fully elucidated, and effective therapy to completely halt DKD progression to ESDR is lacking. This study aimed to identify critical molecular signatures and develop novel therapeutic targets for DKD. This study enrolled 10 datasets consisting of 93 renal samples from the National Center of Biotechnology Information (NCBI) Gene Expression Omnibus (GEO). Networkanalyst, Enrichr, STRING, and Cytoscape were used to conduct the differentially expressed genes (DEGs) analysis, pathway enrichment analysis, protein-protein interaction (PPI) network construction, and hub gene screening. The shared DEGs of type 1 diabetic kidney disease (T1DKD) and type 2 diabetic kidney disease (T2DKD) datasets were performed to identify the shared vital pathways and hub genes. Strepotozocin-induced Type 1 diabetes mellitus (T1DM) rat model was prepared, followed by hematoxylin & eosin (HE) staining, and Oil Red O staining to observe the lipid-related morphological changes. The quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was conducted to validate the key DEGs of interest from a meta-analysis in the T1DKD rat. Using meta-analysis, 305 shared DEGs were obtained. Among the top 5 shared DEGs, Tmem43, Mpv17l, and Slco1a1, have not been reported relevant to DKD. Ketone body metabolism ranked in the top 1 in the KEGG enrichment analysis. Coasy, Idi1, Fads2, Acsl3, Oxct1, and Bdh1, as the top 10 down-regulated hub genes, were first identified to be involved in DKD. The qRT-PCR verification results of the novel hub genes were mostly consistent with the meta-analysis. The positive Oil Red O staining showed that the steatosis appeared in tubuloepithelial cells at 6 w after DM onset. Taken together, abnormal ketone body metabolism may be the key factor in the progression of DKD. Targeting metabolic abnormalities of ketone bodies may represent a novel therapeutic strategy for DKD. These identified novel molecular signatures in DKD merit further clinical investigation.

Abstract
Despite decades of study on the contribution of growth hormone (GH) to the development of kidney disease, there remains the question of the relative contribution of elevated levels of GH to kidney damage in humans, particularly in diabetic nephropathy occurring in type 1 patients. In this study, we reviewed several publicly available datasets to examine transcription of twelve genes associated with the GH/IGF1 axis in several types of human and rodent kidney diseases. Our analyses revealed downregulation of renal GHR and IGF1 gene expression in several different chronic human kidney diseases, including diabetic nephropathy, with general upregulation of IGFBP6 in the same tissues and diseases. These findings were generally supported by a review of studies in rodent models. In healthy and diseased human kidneys, increased GHR gene expression was associated with increases in glomerular filtration rate (GFR) and decreases in serum creatinine. IGFBP6 gene expression demonstrated the opposite clinical correlation. Our results suggest the kidney may exhibit GH insensitivity due to low GHR gene expression during most chronic kidney diseases.

Abstract
AIMS Diabetic Nephropathy (DN) is rarely encountered in childhood, otherwise early subclinical abnormalities are detectable few years after diabetes diagnosis. Our aim was to evaluate the incidence rate of microalbuminuria in childhood onset type 1 diabetes (DM1) patients. Secondary aim was to examine which variables could influence the development of DN. METHODS We longitudinally evaluated 137 young patients with DM1 from diagnosis (1994-2004) for a median of 11.8 years (1st-3rd q: 9.7-15.0). Overnight albumin excretion rate, degree of metabolic control, presence of microangiopathic complications and autoimmune co-morbidities were retrospectively collected. RESULTS DN was observed in 16/137 cases (11.7%), with an incidence rate of 10.0 per 1000 person-years. Young T1D patients with persistent micro/macro-albuminuria were more likely to have higher HbA1c concentrations over the last four years (P = 0.04), and were more likely to have retinopathy (P = 0.011) and subclinical peripheral neuropathy (P = 0.003). CONCLUSIONS DN predictors were age at DM1 diagnosis and mean HbA1c levels. Even if DN incidence is lower than reported, periodical screening is mandatory. Moreover, borderline microalbuminuria as additional risk factor deserves attention.

Abstract
The advanced glycation end‑product (AGE)‑receptor for AGE (RAGE) axis induces transforming growth factor‑β (TGF‑β) expression, cell hypertrophy and increases extracellular matrices that are indicated in the pathogenesis of diabetic nephropathy (DN). RAGE binds to numerous ligands besides AGE, including S100B. In the present study, the roles of S100B in high glucose‑induced p21WAF1, extracellular matrices, TGF‑βl and cell hypertrophy in mouse mesangial (MES13) cells were investigated. High glucose (30 mM) time‑dependently (24‑72 h) induced S100B expression. High glucose and exogenous S100B (1 µM) time‑dependently increased p21WAF1 gene transcription and protein expression, increased type IV collagen and fibronectin protein expression, and TGF‑β gene transcription and bioactivity. Exogenous S100B also time‑dependently activated the extracellular regulated kinases (ERK1/2), p38 kinase and c‑Jun N‑terminal kinase (JNK) signaling pathways. Exogenous S100B‑induced TGF‑β gene transcription and bioactivity were attenuated by SB203580 (p38 kinase inhibitor) and PD98059 (ERK1/2 inhibitor). Finally, the knockdown of S100B by small interfering RNA (siRNA) attenuated high glucose‑induced TGF‑β gene transcription and bioactivity, type IV collagen and fibronectin protein expression and p21WAF1 protein expression. Thus, S100B induced TGF‑β via the ERK1/2 and p38 kinase pathways in mesangial cells. Additionally, high glucose‑induced pro‑fibrotic genes (TGF‑β, type IV collagen and fibronectin) and cell hypertrophy‑related p21WAF1 are dependent on S100B.

Abstract
Impaired kidney function is a well-recognized complication following liver transplantation (LT). Studies of this complication in children have been limited by small numbers and insensitive outcome measures. Our aim was to define the prevalence of, and identify risk factors for, post-LT kidney dysfunction in a multicenter pediatric cohort using measured glomerular filtration rate (mGFR). We conducted a cross-sectional study of 397 patients enrolled in the Studies in Pediatric Liver Transplantation (SPLIT) registry, using mGFR < 90 mL/min/1.73 m(2) as the primary outcome measure. Median age at LT was 2.2 years. Primary diagnoses were biliary atresia (44.6%), fulminant liver failure (9.8%), metabolic liver disease (16.4%), chronic cholestatic liver disease (13.1%), cryptogenic cirrhosis (4.3%) and other (11.8%). At a mean of 5.2 years post-LT, 17.6% of patients had a mGFR < 90 mL/min/1.73 m(2) . In univariate analysis, factors associated with this outcome were transplant center, age at LT, primary diagnosis, calculated GFR (cGFR) at LT and 12 months post-LT, primary immunosuppression, early post-LT kidney complications, age at mGFR, height and weight Z-scores at 12 months post-LT. In multivariate analysis, independent variables associated with a mGFR <90 mL/min/1.73 m(2) were primary immunosuppression, age at LT, cGFR at LT and height Z-score at 12 months post-LT.
