Zhang Q, Pan Y, Ma X, Yang H, Chang J, Hong L, Yan H, Zhang SH. Elevated Secretion of Aldosterone Increases TG/HDL-C Ratio and Potentiates The Ox-LDL-Induced Dysfunction of HUVEC. CELL JOURNAL 2021; 23:61-69. [PMID: 33650821 PMCID: PMC7944123 DOI: 10.22074/cellj.2021.7033] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Accepted: 09/28/2019] [Indexed: 12/19/2022]
Abstract
Objective Atherosclerosis (AS) is one of the most common causes of human death and disability. This study is
designed to investigate the roles of aldosterone (Aldo) and oxidized low-density lipoprotein (Ox-LDL) in this disease by
clinical data and cell model.
Materials and Methods In this experimental study, clinical data were collected to investigate the Aldo role for the
patients with primary aldosteronism or adrenal tumors. Cell viability assay, fluorescence-activated cell sorting (FACS)
assay, apoptosis assay, cell aging analysis, and matrigel tube formation assay were performed to detect effects on
human umbilical vein endothelial cells (HUVECs) treated with Aldo and/or Ox-LDL. Quantitative polymerase chain
reaction (qPCR) and Western blot analysis were performed to figure out critical genes in the process of endothelial cells
dysfunction induced by Aldo and/or Ox-LDL.
Results We found that the Aldo level had a positive correlation with the TG/HDL-C ratio. Endothelial cell growth,
angiogenesis, senescence, and apoptosis were significantly affected, and eNOS/Sirt1, the value of Bcl-2/Bax and
Angiopoietin1/2 were significantly affected when cells were co-treated by Aldo and Ox-LDL.
Conclusion Elevated Aldo with high Ox-LDL together may accelerate the dysfunction of HUVEC, and the Ox-LDL,
especially for those patients with high Aldo should be well controlled. The assessment of the role of Aldo may provide
a theoretical basis for the effective prevention and investigation of a new treatment of AS.

Role of Endoplasmic Reticulum Stress in Atherosclerosis and Its Potential as a Therapeutic Target. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:9270107. [PMID: 32963706 PMCID: PMC7499294 DOI: 10.1155/2020/9270107] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 07/29/2020] [Accepted: 08/24/2020] [Indexed: 12/21/2022]
Abstract
Endoplasmic reticulum (ER) stress is closely associated with atherosclerosis and related cardiovascular diseases (CVDs). It occurs due to various pathological factors that interfere with ER homeostasis, resulting in the accumulation of unfolded or misfolded proteins in the ER lumen, thereby causing ER dysfunction. Here, we discuss the role of ER stress in different types of cells in atherosclerotic lesions. This discussion includes the activation of apoptotic and inflammatory pathways induced by prolonged ER stress, especially in advanced lesional macrophages and endothelial cells (ECs), as well as common atherosclerosis-related ER stressors in different lesional cells, which all contribute to the clinical progression of atherosclerosis. In view of the important role of ER stress and the unfolded protein response (UPR) signaling pathways in atherosclerosis and CVDs, targeting these processes to reduce ER stress may be a novel therapeutic strategy.
