Abstract
Belt electrode-skeletal muscle electrical stimulation (B-SES) involves the use of belt-shaped electrodes to contract multiple muscle groups simultaneously. Twitch contractions have been demonstrated to protect against denervation-induced muscle atrophy in rats, possibly through mitochondrial biosynthesis. This study examined whether inducing tetanus contractions with B-SES suppresses muscle atrophy and identified the underlying molecular mechanisms. We evaluated the effects of acute (60 Hz, 5 min) and chronic (60 Hz, 5 min, every alternate day for one week) B-SES on the tibialis anterior (TA) and gastrocnemius (GAS) muscles in Sprague-Dawley rats using belt electrodes attached to both ankle joints. After acute stimulation, a significant decrease in the glycogen content was observed in the left and right TA and GAS, suggesting that B-SES causes simultaneous contractions in multiple muscle groups. B-SES enhanced p70S6K phosphorylation, an indicator of the mechanistic target of rapamycin complex 1 activity. During chronic stimulations, rats were divided into control (CONT), denervation-induced atrophy (DEN), and DEN + electrically stimulated with B-SES (DEN + ES) groups. After seven days of treatment, the wet weight (n = 8-11 for each group) and muscle fiber cross-sectional area (CSA, n = 6 for each group) of the TA and GAS muscles were reduced in the DEN and DEN + ES groups compared with that in the CON group. The DEN + ES group showed significantly higher muscle weight and CSA than those in the DEN group. Although RNA-seq and pathway analysis suggested that mitochondrial biogenesis is a critical event in this phenomenon, mitochondrial content showed no difference. In contrast, ribosomal RNA 28S and 18S (n = 6) levels in the DEN + ES group were higher than those in the DEN group, even though RNA-seq showed that the ribosome biogenesis pathway was reduced by electrical stimulation. The mRNA levels of the muscle proteolytic molecules atrogin-1 and MuRF1 were significantly higher in DEN than those in CONT. However, they were more suppressed in DEN + ES than those in DEN. In conclusion, tetanic electrical stimulation of both ankles using belt electrodes effectively reduced denervation-induced atrophy in multiple muscle groups. Furthermore, ribosomal biosynthesis plays a vital role in this phenomenon.

[PMID: 37927162 DOI: 10.1111/odi.14799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2023] [Revised: 10/12/2023] [Accepted: 10/23/2023] [Indexed: 11/07/2023]
Abstract
OBJECTIVE There is a strong relationship between masticatory muscle atrophy and condyle degeneration. Although electrical stimulation (ES) is an effective treatment for muscle atrophy, its influence on the underlying condyle is unclear. This study aimed to investigate whether ES can prevent condyle degradation during the stage of masseter muscle atrophy. MATERIALS AND METHODS Six-week-old rats were randomly divided into the control, botulinum toxin (BTX), or BTX + ES group. BTX was injected into the bilateral masseters of rats to induce masseter atrophy. The left-side masseters without ES treatment were served as BTX group, and the right-side masseters received ES with different parameters (5 mA/10 Hz, 5 mA/50 Hz, 6 mA/10 Hz, 6 mA/50 Hz, 7 mA/10 Hz, and 7 mA/50 Hz) were served as BTX + ES groups. After 4 weeks, micro-CT and qualitative or quantitative analysis of osteogenesis, chondrogenesis, and angiogenesis-related genes in condyles were conducted. RESULTS ES, especially at 7 mA/50 Hz, significantly attenuated masseter atrophy, condyle degeneration, and subchondral bone loss. Moreover, the upregulation of related proteins, including collagen 1, osteocalcin, bone morphogenetic protein 2, collagen 2a, and vascular endothelial growth factor were observed. CONCLUSION ES partly rescued condylar degeneration and subchondral bone loss following masseter atrophy.

Abstract
Belt electrode skeletal muscle electrical stimulation (B-SES) can simultaneously contract multiple muscle groups. Although the beneficial effects of B-SES in clinical situations have been elucidated, its molecular mechanism remains unknown. In this study, we developed a novel rodent B-SES ankle stimulation system to test whether low-frequency stimulation prevents denervation-induced muscle atrophy. Electrical stimulations (7‒8 Hz, 30 min) with ankle belt electrodes were applied to Sprague-Dawley rats daily for one week. All animals were assigned to the control (CONT), denervation-induced atrophy (DEN), and DEN + electrical stimulation (ES) groups. The tibialis anterior (TA) and gastrocnemius (GAS) muscles were used to examine the effect of ES treatment. After seven daily sessions of continuous stimulation, muscle wet weight (n = 8-11), and muscle fiber cross-sectional area (CSA, n = 4-6) of TA and GAS muscles were lower in DEN and DEN + ES than in CON. However, it was significantly higher in DEN than DEN + ES, showing that ES partially prevented muscle atrophy. PGC-1α, COX-IV, and citrate synthase activities (n = 6) were significantly higher in DEN + ES than in DEN. The mRNA levels of muscle proteolytic molecules, Atrogin-1 and Murf1, were significantly higher in DEN than in CONT, while B-SES significantly suppressed their expression (p < 0.05). In conclusion, low-frequency electrical stimulation of the bilateral ankles using belt electrodes (but not the pad electrodes) is effective in preventing denervation-induced atrophy in multiple muscles, which has not been observed with pad electrodes. Maintaining the mitochondrial quantity and enzyme activity by low-frequency electrical stimulation is key to suppressing muscle protein degradation.

Abstract
OBJECTIVE To improve lateral thyroarytenoid (TA) muscle atrophy after laryngeal paralysis, reconstruction of the vascular network of the atrophied muscle is necessary. We therefore evaluated whether the controlled release of basic fibroblast growth factor (bFGF) with autologous fascia implantation could affect vascular reconstruction in the lateral TA muscle. STUDY DESIGN Animal experiment. SETTING Laboratory. METHODS Unilateral laryngeal paralysis was induced in 20 rats. The rats were implanted with autologous fascia and a gelatin hydrogel sheet with or without 1 µg of bFGF (fascia and bFGF + fascia groups; n = 5 each) and with only a gelatin hydrogel sheet with bFGF (bFGF group: n = 5). Another group remained untreated (n = 5) at 4 months after paralysis. At 3 months since transplantation, intra- and intergroup comparisons of the muscle volumes and total area of blood vessels in the lateral TA muscle were performed. RESULTS When compared with the untreated group, the bFGF + fascia group showed a significant increase in muscle volume (P =.0008) and vascular area (P =.0002) in the lateral TA muscle, whereas the other 2 treated groups demonstrated an insufficient effect. CONCLUSION bFGF + fascia implantation showed histologic improvement in severe laryngeal paralysis. We demonstrated that the decrease in lateral TA muscle mass after paralysis might be countered by the reconstruction of the vascular network. Our findings indicate that hypovascular and denervated areas of the laryngeal muscle can be regenerated by the implantation of growth factors and scaffolds with surgical stress. LEVEL OF EVIDENCE 5.

Abstract
Skeletal muscle is the largest organ of the body, the development of skeletal muscle is very important for the health of the animal body. Prolyl hydroxylases (PHDs) are the classical regulator of the hypoxia inducible factor (HIF) signal pathway, many researchers found that PHDs are involved in the muscle fiber type transformation, muscle regeneration, and myocyte differentiation. However, whether PHDs can impact the protein turnover of skeletal muscle is poorly understood. In this study, we constructed denervated muscle atrophy mouse model and found PHD3 was highly expressed in the atrophic muscles and there was a significant correlation between the expression level of PHD3 and skeletal muscle weight which was distinct from PHD1 and PHD2. Then, the similar results were getting from the different weight muscles of normal mice. To further verify the relationship between PHD3 and skeletal muscle protein turnover, we established a PHD3 interference model by injecting PHD3 sgRNA virus into tibialis anterior muscle (TA) muscle of MCK-Cre-cas9 mice and transfecting PHD3 shRNA lentivirus into primary satellite cells. It was found that the Knock-out of PHD3 in vivo led to a significant increase in muscle weight and muscle fiber area (P < .05). Besides, the activity of protein synthesis signal pathway increased significantly, while the protein degradation pathway was inhibited evidently (P < .05). In vitro, the results of 5-ethynyl-2'-deoxyuridine (EdU) and tetramethylrhodamine ethyl ester (TMRE) fluorescence detection showed that PHD3 interference could lead to a decrease in cell proliferation and an increase of cell apoptosis. After the differentiation of satellite cells, the production of puromycin in the interference group was higher than that in the control group, and the content of 3-methylhistidine in the interference group was lower than that in the control group (P < .05) which is consistent with the change of protein turnover signal pathway in the cell. Mechanistically, there is an interaction between PHD3, NF-κB, and IKBα which was detected by immunoprecipitation. With the interfering of PHD3, the expression of the inflammatory signal pathway also significantly decreased (P < .05). These results suggest that PHD3 may affect protein turnover in muscle tissue by mediating inflammatory signal pathway. Finally, we knocked out PHD3 in denervated muscle atrophy mice and LPS-induced myotubes atrophy model. Then, we found that the decrease of PHD3 protein level could alleviate the muscle weight and muscle fiber reduction induced by denervation in mice. Meanwhile, the protein level of the inflammatory signal pathway and the content of 3-methylhistidine in denervated atrophic muscle were also significantly reduced (P < .05). In vitro, PHD3 knock-out could alleviate the decrease of myotube diameter induced by LPS, and the expression of protein synthesis pathway was also significantly increased (P < .05). On the contrary, the expression level of protein degradation and inflammatory signal pathway was significantly decreased (P < .05). Through these series of studies, we found that the increased expression of PHD3 in denervated muscle might be an important regulator in inducing muscle atrophy, and this process is likely to be mediated by the inflammatory NF-κB signal pathway.

Abstract
Mitochondria are both the primary provider of ATP and the pivotal regulator of cell death, which are essential for physiological muscle activities. Ca2+ plays a multifaceted role in mitochondrial function. During muscle contraction, Ca2+ influx into mitochondria activates multiple enzymes related to tricarboxylic acid (TCA) cycle and oxidative phosphorylation, resulting in increased ATP synthesis to meet the energy demand. Pathophysiological conditions such as skeletal muscle denervation or unloading also lead to elevated Ca2+ levels inside mitochondria. However, the outcomes of this steady-state elevation of mitochondrial Ca2+ level include exacerbated reactive oxygen species (ROS) generation, sensitized opening of mitochondrial permeability transition pore (mPTP), induction of programmed cell death, and ultimately muscle atrophy. Previously, both acute and long-term endurance exercises have been reported to activate certain signaling pathways to counteract ROS production. Meanwhile, electrical stimulation is known to help prevent apoptosis and alleviate muscle atrophy in denervated animal models and patients with motor impairment. There are various mechanistic studies that focus on the excitation-transcription coupling framework to understand the beneficial role of exercise and electrical stimulation. Interestingly, a recent study has revealed an unexpected role of rapid mitochondrial Ca2+ transients in keeping mPTP at a closed state with reduced mitochondrial ROS production. This discovery motivated us to contribute this review article to inspire further discussion about the potential mechanisms underlying differential outcomes of physiological mitochondrial Ca2+ transients and pathological mitochondrial Ca2+ elevation in skeletal muscle ROS production.

Abstract
: The preservation of muscle mass and muscle function after weight loss therapy is currently a considerable challenge in the fight against obesity. Muscle mass secretes proteins called myokines that have relevant functions in the regulation of metabolism and health. This study was aimed to evaluate whether a very low-calorie ketogenic (VLCK) diet may modulate myokine levels, in addition to changes in body composition, compared to a standard, balanced low-calorie (LC) diet or bariatric surgery in patients with obesity. Body composition, ketosis, insulin sensitivity and myokines were evaluated in 79 patients with overweight/obesity after a therapy to lose weight with a VLCK diet, a LC diet or bariatric surgery. The follow-up was 6 months. The weight loss therapies induced changes in myokine levels in association with changes in body composition and biochemical parameters. The effects on circulating myokine levels compared to those at baseline were stronger after the VLCK diet than LC diet or bariatric surgery. Differences reached statistical significance for IL-8, MMP2 and irisin. In conclusion, nutritional interventions or bariatric surgery to lose weight induces changes in circulating myokine levels, being this effect potentially most notable after following a VLCK diet.

Abstract
Skeletal muscle has a remarkable regenerative capacity in response to mild injury. However, when muscle is severely injured, muscle regeneration is impaired due to the loss of muscle-resident stem cells, known as satellite cells. Fibrotic tissue, primarily comprising collagen I (COL), is deposited with this critical loss of muscle. In recent studies, supplementation of laminin (LM)-111 has been shown to improve skeletal muscle regeneration in several models of disease and injury. Additionally, electrical stimulation (E-stim) has been investigated as a possible rehabilitation therapy to improve muscle's functional recovery. This study investigated the role of E-stim and substrate in regulating myogenic response. C2C12 myoblasts were allowed to differentiate into myotubes on COL- and LM-coated polydimethylsiloxane molds. The myotubes were subjected to E-stim and compared with nonstimulated controls. While E-stim resulted in increased myogenic activity, irrespective of substrate, LM supported increased proliferation and uniform distribution of C2C12 myoblasts. In addition, C2C12 myoblasts cultured on LM showed higher Sirtuin 1, mammalian target of rapamycin, desmin, nitric oxide, and vascular endothelial growth factor expression. Taken together, these results suggest that an LM substrate is more conducive to myoblast growth and differentiation in response to E-stim in vitro.

Abstract
In recent years, electrical myostimulation (EMS) is becoming more and more popular to increase muscle function and muscle weight. Especially it is applied in healthy individual after injury to rebuild muscle mass and in severely atrophic patients who are not able or willing to perform conventional exercise training programs. Studies in experimental models as well as in human subjects confirmed that EMS can increase muscle mass by around 1% and improve muscle function by around 10-15% after 5-6 weeks of treatment. Despite a severe increase in circulating creatine kinase during the first session, EMS can be regarded as a safe therapeutic intervention. At the molecular level, EMS improves the anabolic/catabolic balance and stimulates the regenerative capacity of satellite cells. EMS intensity should be as high as individually tolerated, and a minimum of three sessions per week [large pulses (between 300-450 μs), high frequency (50-100 Hz in young and around 30 Hz in older individuals)] for at least 5-6 weeks should be performed. EMS improved functional performances more effectively than voluntary training and counteracted fast type muscle fibre atrophy, typically associated with sarcopenia. The effect of superimposing EMS on conventional exercise training to achieve more muscle mass and better function is still discussed controversially. Nevertheless, EMS should not be regarded as a replacement of exercise training per se, since the beneficial effect of exercise training is not just relying on building muscle mass but it also exerts positive effects on endothelial, myocardial, and cognitive function.

Effects of Streptomycin Administration on Increases in Skeletal Muscle Fiber Permeability and Size Following Eccentric Muscle Contractions. Anat Rec (Hoboken) 2018; 301:1096-1102.

Abstract
The purpose of this study was to investigate the preventive effect of streptomycin (Str) administration on changes in membrane permeability and the histomorphological characteristics of damaged muscle fibers following eccentric contraction (ECC ). Eighteen 7-week-old male Fischer 344 rats were randomly assigned to three groups: control (Cont), ECC, and ECC with Str (ECC + Str). The tibialis anterior (TA) muscles in both ECC groups were stimulated electrically and exhibited ECC. Evans blue dye (EBD), a marker of muscle fiber damage associated with increased membrane permeability, was injected 24 hr before TA muscle sampling. The number of EBD-positive fibers, muscle fiber cross-sectional area (CSA), and roundness were determined via histomorphological analysis. The ECC intervention resulted in an increased fraction of EBD-positive fibers, a larger CSA, and decreased roundness. The fraction of EBD-positive fibers was 79% lower in the ECC + Str group than in the ECC group. However, there was no difference in the CSA and roundness of the EBD-positive fibers between the two ECC groups. These results suggest that Str administration can reduce the number of myofibers that increase membrane permeability following ECC, but does not ameliorate the extent of fiber swelling in extant EBD-positive fibers.
