[PMID: 31597276 PMCID: PMC6801606 DOI: 10.3390/ijms20194955] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Revised: 09/28/2019] [Accepted: 10/03/2019] [Indexed: 12/21/2022] Open
Abstract
Chrysanthemum boreale Makino essential oil (CBMEO) has diverse biological activities including a skin regenerating effect. However, its role in muscle atrophy remains unknown. This study explored the effects of CBMEO and its active ingredients on skeletal muscle atrophy using in vitro and in vivo models of muscle atrophy. CBMEO reversed the size decrease of L6 myoblasts under starvation. Among the eight monoterpene compounds of CBMEO without cytotoxicity for L6 cells, sabinene induced predominant recovery of reductions of myotube diameters under starvation. Sabinene diminished the elevated E3 ubiquitin ligase muscle ring-finger protein-1 (MuRF-1) expression and p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase1/2 (ERK1/2) phosphorylations in starved myotubes. Moreover, sabinene decreased the increased level of reactive oxygen species (ROS) in myotubes under starvation. The ROS inhibitor antagonized expression of MuRF-1 and phosphorylation of MAPKs, which were elevated in starved myotubes. In addition, levels of muscle fiber atrophy and MuRF-1 expression in gastrocnemius from fasted rats were reduced after administration of sabinene. These findings demonstrate that sabinene, a bioactive component from CBMEO, may attenuate skeletal muscle atrophy by regulating the activation mechanism of ROS-mediated MAPK/MuRF-1 pathways in starved myotubes, probably leading to the reverse of reduced muscle fiber size in fasted rats.

Saneyasu T, Honda K, Kamisoyama H. Myostatin Increases Smad2 Phosphorylation and Atrogin-1 Expression in Chick Embryonic Myotubes. J Poult Sci 2019; 56:224-230. [PMID: 32055218 PMCID: PMC7005388 DOI: 10.2141/jpsa.0180092] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2018] [Accepted: 11/12/2018] [Indexed: 01/07/2023] Open
Abstract
Skeletal muscle mass is an important trait in poultry meat production. In mammals, myostatin, a negative regulator of skeletal muscle growth, activates Smad transcription factors and induces the expression of atrogin-1 by regulating the Akt/FOXO pathway. Although the amino acid sequence of chicken myostatin is known to be completely identical to its mammalian counterpart, previous studies in chicken skeletal muscles have implied that the physiological roles of chicken myostatin are different from those of mammals. Furthermore, it remains to be elucidated whether myostatin affects cellular signaling factors and atrogin-1 expression. In this study, using chick embryonic myotubes, we found that myostatin significantly increased the phosphorylation rate of Smad2 and mRNA levels of atrogin-1. No significant change was observed in the phosphorylation of Akt and FOXO1. These in vitro results suggest that the molecular mechanisms underlying myostatin-induced expression of atrogin-1 might be different between chickens and mammals.

Differences in strength-duration curves of electrical diagnosis by physiotherapists between DJ-1 homozygous knockout and wild-type mice: a randomized controlled pilot trial. J Phys Ther Sci 2016; 28:1595-8. [PMID: 27313379 PMCID: PMC4905918 DOI: 10.1589/jpts.28.1595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2016] [Accepted: 02/03/2016] [Indexed: 12/01/2022] Open
Abstract
[Purpose] Strength-duration (SD) curves are used in electrical diagnosis by
physiotherapists to confirm muscle degeneration. However, the usefulness of SD curves in
comparing muscle degeneration in DJ-1 homozygous knockout (DJ-1−/−) and
wild-type mice (DJ-1+/+) is not yet fully understood. The electrical properties
of the gastrocnemius muscles of DJ-1−/− and DJ-1+/+ mice were
compared in the current study. [Subjects and Methods] The electrode of an electrical
stimulator was applied to the gastrocnemius muscle to measure the rheobase until the
response of contractive muscle to electrical stimulation became visible in mice. [Results]
The rheobase of DJ-1−/− mice showed a significant increase in a time-dependent
manner, compared to that of DJ-1+/+ mice. [Conclusion] These results
demonstrate that the DJ-1 protein may be implicated in the regulation of neuromuscular
activity of gastrocnemius muscles of mice.

Differences in the body pressure-related sensory changes between the floor and mattress in a static supine position for physiotherapy research: a randomized controlled pilot trial. J Phys Ther Sci 2016; 28:1086-91. [PMID: 27190432 PMCID: PMC4868192 DOI: 10.1589/jpts.28.1086] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2015] [Accepted: 12/18/2015] [Indexed: 11/24/2022] Open
Abstract
[Purpose] This study was performed to investigate the difference in body pressure-related sensory changes between the floor and mattress in a static supine position for physiotherapy research. [Subjects and Methods] To analyze body pressure, the Body Pressure Measurement System was used. Body pressure sensors were attached to mattresses and the floor beneath the subjects. The level of pain was evaluated using pain score tools before the static supine position was adopted, at 1, 5, 10, and 15 min, and in total for specific body points. [Results] In analysis of digitized images, there was no significant difference observed between floor and mattress body pressure values at the start position. However, the head pressure intensity was significantly higher than that of the other body parts. In analysis of pain scores, all body part pain scores except those for both legs were significantly higher for the floor than for the mattress. Furthermore, the pain scores of the floor group were significantly increased at minute 1 compared with those of the mattress group. [Conclusion] These results suggest that properties that change in a time-dependent manner and postural changes need to be carefully considered when applying physical therapy.
