Silencing ATF3 Might Delay TBHP-Induced Intervertebral Disc Degeneration by Repressing NPC Ferroptosis, Apoptosis, and ECM Degradation. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:4235126. [PMID: 35480873 PMCID: PMC9036167 DOI: 10.1155/2022/4235126] [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: 10/07/2021] [Revised: 12/28/2021] [Accepted: 03/21/2022] [Indexed: 02/06/2023]
Abstract
Intervertebral disc degeneration (IDD), being the predominant root cause of lower back pain, has led to an enormous socioeconomic burden in the world. Ferroptosis is an iron-dependent nonapoptotic and nonpyroptotic programmed cell death associated with an increase in reactive oxygen species (ROS), which has been implicated in the pathogenesis of IDD. Activation transcription factor 3 (ATF3) is widely reported to promote ferroptosis and apoptosis in multiple diseases, but its roles and underlying regulatory mechanism in IDD have not been identified. FAoptosis is defined as a mixed cell death consisting of ferroptosis and apoptosis. The loss- and gain-of-function experiments demonstrated that ATF3 positively regulated tert-butyl hydroperoxide- (TBHP-) induced nucleus pulposus cell (NPC) FAoptosis, ROS production, inflammatory response, and extracellular matrix (ECM) degradation. Furthermore, silencing ATF3 ameliorated the progression of IDD in vivo, whereas its overexpression showed the opposite phenotype. Bioinformatics analysis and molecular experiments corroborated that ATF3 is a direct target of miR-874-3p, suggesting that the upregulation of ATF3 in IDD might be caused at least in part due to the downregulation of miR-874-3p in IDD, thereby relieving the inhibition of ATF3 by miR-874-3p. The findings revealed that ATF3 has the potential to be used as a promising therapeutic target against IDD.

Kidney Blood Press Res 2022; 47:81-93. [PMID: 35158353 DOI: 10.1159/000518866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Accepted: 08/03/2021] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION Diabetic kidney disease (DKD) remains the leading cause of chronic kidney disease. Dysregulation of circulating miRNAs has been reported, suggesting their pathological roles in DKD. This study aimed to investigate differentially expressed miRNAs in the sera of type 2 diabetes mellitus (T2DM) patients with and without albuminuria in a selected Malaysian population. METHOD Forty-one T2DM patients on follow-up at a community clinic were divided into normo-(NA), micro-(MIC), and macroalbuminuria (MAC) groups. Differential levels of miRNAs in 12 samples were determined using the pathway-focused (human fibrosis) miScript miRNA qPCR array and was validated in 33 samples, using the miScript custom qPCR array (CMIHS02742) (Qiagen GmbH, Hilden, Germany). RESULTS Trends of upregulation of 3 miRNAs in the serum, namely, miR-874-3p, miR-101-3p, and miR-145-5p of T2DM patients with MAC compared to those with NA. Statistically significant upregulation of miR-874-3p (p = 0.04) and miR-101-3p (p = 0.01) was seen in validation cohort. Significant negative correlations between the estimated glomerular filtration rate (eGFR) and miR-874-3p (p = 0.05), miR-101-3p (p = 0.03), and miR-145-5p (p = 0.05) as well as positive correlation between miR-874-3p and age (p = 0.03) were shown by Pearson's correlation coefficient analysis. CONCLUSION Upregulation of previously known miRNA, namely, miR-145-5p, and possibly novel ones, namely, miR-874-3p and miR-101-3p in the serum of T2DM patients, was found in this study. There was a significant correlation between the eGFR and these miRNAs. The findings of this study have provided encouraging evidence to further investigate the putative roles of these differentially expressed miRNAs in DKD.

Huang G, Zhu Y, Yong C, Tian F, Liu L, Wu Q, Shu Y, Yao M, Tang C, Wang X, Chen W, Zhou E. Artemisia capillaris Thunb. water extract attenuates adriamycin-induced renal injury by regulating apoptosis through the ROS/MAPK axis. J Food Biochem 2022; 46:e14065. [PMID: 34984698 DOI: 10.1111/jfbc.14065] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 12/15/2021] [Accepted: 12/22/2021] [Indexed: 02/06/2023]
Abstract
Artemisia capillaris Thunb. is widely used in the treatment of kidney diseases, but the underlying mechanism remain elusive. Therefore, this study aimed to elucidate the mechanism of Artemisia capillaris Thunb. in alleviating renal injury. And renoprotective effects of freeze-dried powder of Artemisia capillaris Thunb. water extract (WAC) were assessed using adriamycin (ADR)-induced renal injury to the NRK-52E cells and ADR-induced renal injury Sprague-Dawley rats (SD rats) models. The results show that WAC could alleviate ADR-induced renal injury in SD rats and the NRK-52E cell line, improved renal function (BUN 9.73 ± 0.35 vs 7.13 ± 0.15, SCR 80.60 ± 1.68 vs 60.50 ± 1.42, ACR 11.50 ± 0.50 vs 8.526 ± 0.15) or cell viability (IC50 = 1.08 µg/ml (ADR), cell viability increase 36.38% ± 6.74% (added 4 mg/ml WAC)), and reduced the apoptosis. Moreover, WAC inhibited the MAPK signal transduction, increased the expression of superoxide dismutase 1 (SOD1), and decreased the production of ROS. The treatment of N-acetylcysteine (NAC, antioxidant) in vitro showed that NAC inhibited apoptosis and alleviated renal injury by inhibiting oxidative stress and reducing the phosphorylation of proteins related to the MAPK signaling pathway. Therefore, these results suggested that WAC can alleviate ADR-induced renal injury and apoptosis by regulating the ROS/MAPK axis and has potential to be used as a renoprotective drug. PRACTICAL APPLICATIONS: Artemisia capillaris Thunb., which is a medicinal and edible plant, is widely used to treat kidney diseases in traditional Chinese medicine. The present research examined the renal protective effect of Artemisia capillaris Thunb. The results show that Artemisia capillaris Thunb. can effectively reduce renal tubular cell apoptosis through the ROS/MAPK axis in vivo and in vitro. In general, Artemisia capillaris Thunb. can be used as a potential herb to attenuate renal injury and further research can be conducted to explore its renoprotective mechanisms.

[PMID: 34178027 PMCID: PMC8226233 DOI: 10.3389/fgene.2021.656759] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Accepted: 04/15/2021] [Indexed: 12/15/2022] Open
Abstract
The functional alteration of nucleus pulposus cells (NPCs) exerts a crucial role in the occurrence and progression of intervertebral disk degeneration (IDD). Circular RNAs and microRNAs (miRs) are critical regulators of NPC metabolic processes such as growth and apoptosis. In this study, bioinformatics tools, encompassing Gene Ontology pathway and Venn diagrams analysis, and protein–protein interaction (PPI) network construction were used to identify functional molecules related to IDD. PPI network unveiled that ESR1 was one of the most critical genes in IDD. Then, a key IDD-related circ_0040039-miR-874-3p-ESR1 interaction network was predicted and constructed. Circ_0040039 promoted miR-874-3p and repressed ESR1 expression, and miR-874-3p repressed ESR1 expression in NPCs, suggesting ESR1 might be a direct target of miR-874-3p. Functionally, circ_0040039 could enhance NPC apoptosis and inhibit NPC growth, revealing that circ_0040039 might aggravate IDD by stabilizing miR-874-3p and further upregulating the miR-874-3p-ESR1 pathway. This signaling pathway might provide a novel therapeutic strategy and targets for the diagnosis and therapy of IDD-related diseases.
