Abstract
Diabetic kidney disease (DKD) is a severe diabetic complication that affects up to half of the individuals with diabetes. Elevated blood glucose levels are a key underlying cause of DKD, but DKD is a complex multifactorial disease, which takes years to develop. Family studies have shown that inherited factors also contribute to the risk of the disease. During the last decade, genome-wide association studies (GWASs) have emerged as a powerful tool to identify genetic risk factors for DKD. In recent years, the GWASs have acquired larger number of participants, leading to increased statistical power to detect more genetic risk factors. In addition, whole-exome and whole-genome sequencing studies are emerging, aiming to identify rare genetic risk factors for DKD, as well as epigenome-wide association studies, investigating DNA methylation in relation to DKD. This article aims to review the identified genetic and epigenetic risk factors for DKD.

Preliminary Study of Genome-Wide Association Identified Novel Susceptibility Genes for Hemorheological Indexes in a Chinese Population. Transfus Med Hemother 2022; 49:346-357. [PMID: 36654975 PMCID: PMC9768296 DOI: 10.1159/000524849] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Accepted: 05/01/2022] [Indexed: 01/21/2023] Open
Abstract
Background Genome-wide association studies for various hemorheological characteristics have not been reported. We aimed to identify genetic loci associated with hemorheological indexes in a cohort of healthy Chinese Han individuals. Methods Genotyping was performed using Applied Biosystems Axiom™ Precision Medicine Diversity Array in 838 individuals, and 6,423,076 single nucleotide polymorphisms were available for genotyping. The relations were examined in an additive genetic model using mixed linear regression and combined with identical by descent matrix. Results We identified 38 genetic loci (p < 5 × 10-6) related to hemorheological traits. In which, LOC102724502-OLIG2 rs28371438 was related to the levels of nd30 (p = 8.58 × 10-07), nd300 (p = 1.89 × 10-06), erythrocyte rigidity (p = 1.29 × 10-06), assigned viscosity (p = 6.20 × 10-08) and whole blood high cut relative (p = 7.30 × 10-08). The association of STK32B rs4689231 for nd30 (p = 3.85 × 10-06) and nd300 (p = 2.94 × 10-06) and GTSCR1-LINC01541 rs11661911 for erythrocyte rigidity (p = 9.93 × 10-09) and whole blood high cut relative (p = 2.09 × 10-07) was found. USP25-MIR99AHG rs1297329 was associated with erythrocyte rigidity (p = 1.81 × 10-06) and erythrocyte deformation (p = 1.14 × 10-06). Moreover, the association of TMEM232-SLC25A46 rs3985087 and LINC00470-METTL4 rs9966987 for fibrinogen (p = 1.31 × 10-06 and p = 4.29 × 10-07) and plasma viscosity (p = 1.01 × 10-06 and p = 4.59 × 10-07) was found. Conclusion These findings may represent biological candidates for hemorheological indexes and contribute to hemorheological study.

NAC alleviative ferroptosis in diabetic nephropathy via maintaining mitochondrial redox homeostasis through activating SIRT3-SOD2/Gpx4 pathway. Free Radic Biol Med 2022; 187:158-170. [PMID: 35660452 DOI: 10.1016/j.freeradbiomed.2022.05.024] [Citation(s) in RCA: 42] [Impact Index Per Article: 21.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Revised: 05/14/2022] [Accepted: 05/29/2022] [Indexed: 12/16/2022]
Abstract
Diabetic nephropathy (DN) is known as a major microvascular complication in type 1 diabetes. The effect of insulin treatment alone on controlling blood glucose is unsatisfactory. N-acetylcysteine (NAC), a chemical agent with thiol group, is found to confer a protective effect in renal injury. However, whether NAC combined with insulin treatment can further enhance the therapeutic effect in DN remains unclear. Here, we firstly used large mammal beagle as DN model to explore the effect of NAC combined with insulin treatment on DN during 120 d. Our results showed that NAC further alleviated mitochondrial oxidative damage and ferroptosis by enhancing activity of mitochondria GSH and maintaining mitochondrial redox homeostasis in DN. Additionally, the upregulated acetylation level of SOD2 was further abrogated by NAC treatment. In MDCK cells, NAC reduced high glucose (HG)-caused ferroptosis via activating Gpx4 expression. Of note, inhibition of Gpx4 by FIN56 abolished the protective effects of NAC on HG-induced ferroptosis. More importantly, 3-TYP reversed the effect of NAC on the mitochondria ROS under HG treatment, as well as eliminated its following beneficial effects for ferroptosis against HG-stimulated cells. These results reveal that NAC attenuated ferroptosis in DN via maintaining mitochondrial redox homeostasis through activating SIRT3-SOD2-Gpx4 signaling pathway.

Bibliometric Study of Trends in the Diabetic Nephropathy Research Space from 2016 to 2020. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:8050137. [PMID: 35450407 PMCID: PMC9018194 DOI: 10.1155/2022/8050137] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 03/02/2022] [Accepted: 03/17/2022] [Indexed: 12/15/2022]
Abstract
Background Diabetic nephropathy (DN) is one of the most common microvascular complications of diabetes mellitus (DM), but no bibliometric studies pertaining to DN have been published within the last 5 years. Objectives Most prior studies have focused on specific problems in the DN field. This study attempts to sort out and visualize the knowledge framework in this research space from a holistic and highly generalized perspective. Readers can quickly understand and master the knowledge regarding DN research conducted from 2016 to 2020, in addition to predicting future research hotspots and possible directions for development in this field in a comprehensive and scientifically valid manner. Methods Literature information, discourse matrices, and co-occurrence matrices were generated using BICOMB. gCLUTO was used for biclustering analyses and visualization. Strategic diagrams were generated using GraphPad Prism 5. The social network analysis (SNA) was analyzed and plotted using Ucinet 6.0 and Netdraw. Results In total, 55 high-frequency MeSH terms/MeSH subheadings were selected and grouped into 5 clusters in a biclustering analysis. These analyses revealed that extensive studies of the etiology, diagnosis, and treatment of DN have been conducted over the last 5 years, while further research regarding DN-related single nucleotide polymorphisms, miRNAs, and signal transduction are warranted as these research areas remain relatively immature. Conclusion Together, these results outline a robust knowledge structure pertaining to the field of DN-related research over the last 5 years, providing a valuable resource for readers by enabling the easy comprehension of relevant information. In addition, this analysis highlights predicted DN-related research directions and hotspots.
