Abstract
Cellular senescence is a highly stable state associated with cell cycle arrest, that is elicited in response to various stresses. The accumulation of senescent cells in tissues drives age-related diseases. Recent studies have shown that the cellular senescence enhances an extracellular vesicles (EV) secretion. EV are lipid-bilayer-capsuled particles released by various cells mediating cell-to-cell communication. It was recently reported that EV secreted by the senescent cells had several functions such as cancer cell proliferation and immune cell activation. In the present study, we investigated whether senescent cardiac fibroblasts-derived EV play an autocrine/paracrine role in the heart cells. Neonatal rat cardiac fibroblasts (NRCFs) were treated with doxorubicin (DOX) to induce cellular senescence. EV were isolated from NRCFs culture media. The vehicle-treated NRCFs-derived EV (D0-EV, 72 hr) increased a living cell number in NRCFs, which was attenuated by DOX (1,000 nM)-treated NRCFs-derived EV (D103-EV, 72 hr). While D0-EV did not affect protein concentration in NRCFs, D103-EV decreased it. Furthermore, D103-EV significantly increased a ratio of microtubule-associated protein 1 light chain 3 (LC3)-II to LC3-I in NRCFs, indicating an induction of autophagy. In addition, D103-EV increased phosphorylation of adenosine monophosphate-activated kinase (AMPK) α in NRCFs. In neonatal rat cardiomyocytes, however, NRCFs-derived EV (72 hr) had no effect on the living cell number, protein concentration, and ratio of LC3-II to LC3-I. In conclusion, we for the first time revealed that DOX-induced senescent NRCFs-derived EV induce autophagy in NRCFs perhaps partly through the activation of AMPKα.

Circ-Ddx60 contributes to the antihypertrophic memory of exercise hypertrophic preconditioning. J Adv Res 2022; 46:113-121. [PMID: 35718079 PMCID: PMC10105073 DOI: 10.1016/j.jare.2022.06.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 05/27/2022] [Accepted: 06/11/2022] [Indexed: 02/07/2023] Open
Abstract
INTRODUCTION We previously reported a phenomenon called exercise hypertrophic preconditioning (EHP), the underlying mechanisms of which need further clarification. OBJECTIVES We aimed to investigate whether circular RNAs (circRNAs) are involved in EHP. METHODS CircRNA sequencing of myocardial tissue was performed in male C57BL/6 mice with EHP and sedentary. Bioinformatics analysis and Sanger sequencing were used to screen hub circRNA expression and to detect full-length circRNAs, respectively. Loss-of-function analyses were conducted to assess the effects of circ-Ddx60 (c-Ddx) on EHP. After 21 days of swimming training or resting, mice underwent transverse aortic constriction (TAC) or sham surgery. Echocardiography, invasive hemodynamic measurement and histological analysis were used to evaluate cardiac remodeling and function. The presence of interaction between c-Ddx and proteins was investigated using comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP-MS). RESULTS In this study, we identified a novel circRNA, named c-Ddx that was preferentially expressed in myocardial tissue and significantly up-regulated in EHP mice. Silencing of c-Ddx attenuated the antihypertrophic effect of EHP and worsened heart failure in mice that underwent TAC. ChIRP-MS and molecular docking analysis validated the combination of c-Ddx and eukaryotic elongation factor 2 (eEF2). Mechanistically, c-Ddx silencing inhibited the increase of phosphorylation of eEF2 and its upstream AMP-activated protein kinase (AMPK) induced by EHP. CONCLUSIONS C-Ddx contributes to the antihypertrophic memory of EHP by binding and activating eEF2, which would provide opportunity to search new therapeutic targets for pathological hypertrophy of heart.

Small molecule QF84139 ameliorates cardiac hypertrophy via activating the AMPK signaling pathway. Acta Pharmacol Sin 2022; 43:588-601.

Abstract
Cardiac hypertrophy is a common adaptive response to a variety of stimuli, but prolonged hypertrophy leads to heart failure. Hence, discovery of agents treating cardiac hypertrophy is urgently needed. In the present study, we investigated the effects of QF84139, a newly synthesized pyrazine derivative, on cardiac hypertrophy and the underlying mechanisms. In neonatal rat cardiomyocytes (NRCMs), pretreatment with QF84139 (1-10 μM) concentration-dependently inhibited phenylephrine-induced hypertrophic responses characterized by fetal genes reactivation, increased ANP protein level and enlarged cardiomyocytes. In adult male mice, administration of QF84139 (5-90 mg·kg-1·d-1, i.p., for 2 weeks) dose-dependently reversed transverse aortic constriction (TAC)-induced cardiac hypertrophy displayed by cardiomyocyte size, left ventricular mass, heart weights, and reactivation of fetal genes. We further revealed that QF84139 selectively activated the AMPK signaling pathway without affecting the phosphorylation of CaMKIIδ, ERK1/2, AKT, PKCε, and P38 kinases in phenylephrine-treated NRCMs and in the hearts of TAC-treated mice. In NRCMs, QF84139 did not show additive effects with metformin on the AMPK activation, whereas the anti-hypertrophic effect of QF84139 was abolished by an AMPK inhibitor Compound C or knockdown of AMPKα2. In AMPKα2-deficient mice, the anti-hypertrophic effect of QF84139 was also vanished. These results demonstrate that QF84139 attenuates the PE- and TAC-induced cardiac hypertrophy via activating the AMPK signaling. This structurally novel compound would be a promising lead compound for developing effective agents for the treatment of cardiac hypertrophy.

Abstract
Inhalation or systemic administration of lipopolysaccharide (LPS) can induce acute pulmonary inflammation and lung injury. The pulmonary vasculature is composed of pulmonary microvascular endothelial cells (PMVECs), which form a semiselective membrane for gas exchange. The miRNA miR‐642a‐5p has previously been reported to be up‐regulated in patients with acute respiratory distress syndrome; thus, here, we examined whether this miRNA is involved in the effects of LPS on PMVECs. The levels of miR‐642a‐5p and mRNA encoding eukaryotic elongation factor 2 (eEF2) were detected by quantitative RT‐PCR. Moesin and eEF2 protein levels were tested by western blot assay. Dual‐luciferase reporter assay was used to examine the relationship between miR‐642a‐5p and eEF2. Cell viability was assessed using the 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide assay, and cell permeability was analyzed using the transendothelial electrical resistance assay. We report that miR‐642a‐5p levels are significantly up‐regulated in LPS‐stimulated PMVECs, and miR‐642a‐5p contributes to LPS‐induced hyperpermeability and apoptosis of PMVECs. LPS treatment results in down‐regulation of eEF2 in PMVECs. Overexpression of eEF2, a direct target of miR‐642a‐5p, inhibited the effect of LPS on PMVECs. miR‐642a‐5p promoted LPS‐induced hyperpermeability and apoptosis by targeting eEF2. Thus, miR‐642a‐5p and eEF2 may serve as potential targets for acute lung injury/acute respiratory distress syndrome diagnosis or treatment.

Abstract
Stanniocalcin-1 (STC1) secreted by mesenchymal stromal cells (MSCs) has anti-inflammatory functions, reduces apoptosis, and aids in angiogenesis, both in vitro and in vivo. However, little is known about the molecular mechanisms of its regulation. Here, we show that STC1 secretion is increased only under specific cell-stress conditions. We find that this is due to a change in actin stress fibers and actin-myosin tension. Abolishment of stress fibers by blebbistatin and knockdown of the focal adhesion protein zyxin leads to an increase in STC1 secretion. To also study this connection in 3D, where few focal adhesions and actin stress fibers are present, STC1 expression was analyzed in 3D alginate hydrogels and 3D electrospun scaffolds. Indeed, STC1 secretion was increased in these low cellular tension 3D environments. Together, our data show that STC1 does not directly respond to cell stress, but that it is regulated through mechanotransduction. This research takes a step forward in the fundamental understanding of STC1 regulation and can have implications for cell-based regenerative medicine, where cell survival, anti-inflammatory factors, and angiogenesis are critical.

Abstract
Eukaryotic elongation factor 2 (eEF2) kinase (eEF2K) acts to inhibit protein translation
through phosphorylating a specific substrate, eEF2. We previously found that the increased
eEF2K expression in mesenteric artery mediates hypertension development in spontaneously
hypertensive rats. More recently, we have revealed that a selective eEF2K inhibitor,
A484954 induced vasorelaxation via opening inward rectifier K+ channel and
activating β2-adrenergic receptor in smooth muscle of rat isolated mesenteric
artery, which contributes to prevent noradrenaline-induced acute increase in blood
pressure (BP). In this study, we further explored acute effects of A484954 on BP in rats,
especially focusing the action on β-adrenergic receptor. We also examined whether A484954
affects contraction and heart rate (HR) of isolated heart. BP and HR were measured by a
carotid cannulation method in rats. Isometric contraction and HR in rat isolated atria
were also measured pharmacologically. A484954 potentiated adrenaline-induced decrease in
diastolic BP (DBP) but not increase in systolic BP (SBP). A484954 potentiated
isoproterenol-induced decrease in DBP but not SBP. Contrastingly, A484954 prevented a
non-β-adrenergic receptor agonist, angiotensin II-induced increase in both SBP and DBP. In
isolated left atria, A484954 caused contraction, which was prevented by a β-adrenergic
receptor antagonist, propranolol. In isolated right atria, A484954 increased HR. In
conclusion, we for the first time demonstrated that A484954 potentiates β-adrenergic
receptor agonist-induced decrease in DBP possibly through vasorelaxation mediated via
activating β2-adrenergic receptor. It was also demonstrated that A484954 causes
contraction of rat isolated heart via activating β1-adrenergic receptor.
