Effects of acute exercise and allopurinol administration on soluble urokinase plasminogen activator receptor (suPAR).
2013
Background Although physical exercise acutely increases the most widely used inflammatory biomarkers, there is no information on its effect on soluble urokinase plasminogen activating receptor (suPAR), a circulating biomarker increasingly used for the assessment of systemic inflammation. Methods suPAR was assessed with the quantitative suPARnostic Standard ELISA Assay (Virogates, Birkerod, Denmark) in 12 professional football players before and after a football match. The athletes were divided into two experimental groups. An oral dose of 300 mg of allopurinol was administered to one group of six participants four hours before a match; the other six participants received placebo. Results Se…
Extracellular vesicles and high‐density lipoproteins: Exercise and oestrogen‐responsive small RNA carriers
2023
Decreased systemic oestrogen levels (i.e., menopause) affect metabolic health. However, the detailed mechanisms underlying this process remain unclear. Both oestrogens and exercise have been shown to improve metabolic health, which may be partly mediated by circulating microRNA (c-miR) signalling. In recent years, extracellular vesicles (EV) have increased interest in the field of tissue crosstalk. However, in many studies on EV-carried miRs, the co-isolation of high-density lipoprotein (HDL) particles with EVs has not been considered, potentially affecting the results. Here, we demonstrate that EV and HDL particles have distinct small RNA (sRNA) content, including both host and nonhost sRN…
MicroRNAs in Extracellular Vesicles in Sweat Change in Response to Endurance Exercise
2020
Background: To date, microRNAs (miRs) carried in extracellular vesicles (EVs) in response to exercise have been studied in blood but not in non-invasively collectable body fluids. In the present study, we examined whether six exercise–responsive miRs, miRs-21, -26, -126, -146, -221, and -222, respond to acute endurance exercise stimuli of different intensities in sweat. Methods: We investigated the response of miRs isolated from sweat and serum EVs to three endurance exercise protocols: (1) maximal aerobic capacity (VO2max), (2) anaerobic threshold (AnaT), and (3) aerobic threshold (AerT) tests. Sauna bathing was used as a control test to induce sweating through increased body temperature i…
