In vitro ischemic preconditioning mediates the Ca 2+/CaN/NFAT pathway to protect against oxygen-glucose deprivation-induced cellular damage and inflammatory responses. Brain Res 2024; 1826:148736. [PMID: 38141801 DOI: 10.1016/j.brainres.2023.148736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 12/17/2023] [Accepted: 12/18/2023] [Indexed: 12/25/2023]
Abstract
Oxygen-glucose deprivation (OGD) is a critical model for studying hypoxic-ischemic cerebrovascular disease in vitro. This paper is to investigate the protection of OGD-induced cellular damage and inflammatory responses by OGD preconditioning in vitro, to provide a theoretical basis for OGD preconditioning to improve the prevention and prognosis of ischemic stroke. OGD or OGD preconditioning model was established by culturing the PC12 cell line in vitro, followed by further adding A23187 (calcium ion carrier) or CsA (calcium ion antagonist). Cell viability was detected by MTT, apoptosis by Hoechst 33,258 staining, the levels of TNF-α and IL-1β mRNA by RT-qPCR and ELISA, and the levels of CaN, NFAT, COX-2 by RT-qPCR and Western blot. Cell viability was decreased, and apoptosis, inflammatory cytokines, and CaN, NFAT, and COX-2 levels were notably increased upon OGD, while OGD pretreatment significantly increased cell viability and decreased apoptosis, inflammation, and the Ca2+/CaN/NFAT pathway. Treatment with A23187 decreased cell viability, promoted apoptosis, and significantly increased TNF-α, IL-1β, CaN, NFAT, and COX-2 levels, while CsA treatment reduced the opposite results. In vitro OGD preconditioning mediates the Ca2+/CaN/NFAT pathway to protect against OGD-induced cellular damage and inflammatory responses.

Melatonin prevents calcineurin-activated the nuclear translocation of nuclear factor of activated T-cells in human neuroblastoma SH-SY5Y cells undergoing hydrogen peroxide-induced cell death. J Chem Neuroanat 2020; 106:101793. [PMID: 32348875 DOI: 10.1016/j.jchemneu.2020.101793] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Revised: 04/02/2020] [Accepted: 04/03/2020] [Indexed: 02/06/2023]
Abstract
The interaction between the activation of protein phosphatase, calcineurin (CaN), and the dephosphorylation and nuclear translocation of nuclear factor of activated T-cells (NFAT), a transcriptional factor in the immune system, has attracted interest as a key factor responsible for the cell death process. In this study, the effects of melatonin on the interaction between CaN and NFAT signaling during oxidative stress-induced cell death were investigated. Human neuroblastoma SH-SY5Y cells were treated with the non-radical reactive oxygen species hydrogen peroxide (H2O2). Cells were treated with 200 μM H2O2 for the indicated time. Some H2O2-treated cells were pretreated with melatonin for 1 h. Control cells were treated with the same concentration of ethanol used to dilute melatonin. H2O2-induced cell death promoted increases in reactive oxygen species (ROS) production and the nuclear translocation of NFAT, which were related to increased levels the active, cleaved form of CaN (32.5 kDa). In addition, pretreatment of H2O2-treated cells with melatonin decreased cell death, ROS production, the levels of the active-cleaved form of CaN and the nuclear translocation of NFAT. Based on these findings, melatonin may exert its neuroprotective effects on oxidative damage-induced cell death by inhibiting CaN-activated the nuclear translocation of NFAT.

Synaptopodin-2 promotes hepatocellular carcinoma metastasis via calcineurin-induced nuclear-cytoplasmic translocation. Cancer Lett 2020; 482:8-18.

Abstract
Hepatocellular carcinoma (HCC), a type of malignant liver tumor, has a grim prognosis. As a functional protein, synaptopodin-2 (SYNPO2) has been associated with malignancy; however, the expression profile and function of SYNPO2 in HCC remains unknown. Herein, we revealed that SYNPO2 was transcriptionally downregulated in HCC tissues from both The Cancer Genome Atlas cohort and our cohort, and was also decreased at the translational level as determined by western blotting and immunohistochemical staining. Furthermore, reduced SYNPO2 expression correlated significantly with short overall survival and recurrence free survival of HCC patients. Restoring SYNPO2 expression inhibited the proliferation and aggressiveness of hepatocarcinoma cells. Mechanistically, increasing the ratio of cytoplasmic SYNPO2 to nuclear SYNPO2 was positively associated with recurrence rate in HCC patients; calcineurin (CaN) activity positively correlated with cytoplasmic SYNPO2 levels in HCC tissues; and nuclear-cytoplasmic translocation of SYNPO2 was induced by CaN to facilitate metastasis of HCC through assembly of peripheral actin bundles. In short, our findings uncover a novel role of SYNPO2 in HCC metastasis via the CaN/SYNPO2/F-actin axis, and indicate that SYNPO2 may serve as a possible prognostic marker and novel therapeutic target.

Effect of Hypoxia on the Muscle Fiber Switching Signal Pathways CnA/NFATc1 and Myostatin in Mouse Myocytes. Acta Histochem 2019; 121:539-545. [PMID: 31047685 DOI: 10.1016/j.acthis.2019.04.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Revised: 03/16/2019] [Accepted: 04/01/2019] [Indexed: 12/13/2022]
Abstract
This study investigated the effects of a CoCl2-simulated hypoxic environment on the muscle fiber switching signaling pathways calcineurin A/nuclear factor of activated T cells cytoplasmic 1 (CnA/NFATc1) and myostatin. In this study, C2C12 muscle cells were cultured in vitro under CoCl2-simulated chemical hypoxic conditions, the expression levels of CnA and myostatin were detected through qRT-PCR and Western blot analyses, and a positioning study of NFATc1 was carried out by immunofluorescence labeling. Results showed that CoCl2 treatment significantly increased the expression levels of CnA and myostatin. Moreover, the position of NFATc1 expression changed; actually, its expression in the nucleus considerably increased. Furthermore, CoCl2-induced hypoxia inhibited the differentiation of C2C12 cells and reduced the expression levels of many slow- and fast-twitch muscles marker genes, but immunofluorescence staining results showed that the proportion of MyHC I type muscle fiber increased after CoCl2 treatment. The hypoxic environment simulated by CoCl2 can activate the signaling pathways CnA/NFATc1 and myostatin and increases the proportion of MyHC I type muscle fibers.
