Abstract
In the present investigation one compound, 2,6-dimethoxy benzoquinone (FJL-1), was isolated from the dichloromethane (DCM) fraction of the organic leaf extract of Flacourtia Jangomas for the first time. The compound structure was elucidated using extensive spectral analysis, including 1H, and 13C NMR. Furthermore, the DPPH and ABTS methods were used to evaluate the antioxidant activity of the organic extract, its fractions, and the isolated compound FJL-1. Antioxidant activity of the petroleum, ether, DCM, and methanol fractions of the organic extract and the isolated compound of F. Jangomas revealed moderate to strong radical scavenging ability. Additionally, the antimicrobial activity of FJL-1 against Staphylococcus aureus (MTCC 737 and MTCC 96 strains) was observed in an inhibition zone size of 21.6 ± 0.6 to 21.7 ± 0.58 mm showing potential inhibitory activity. The isolated compound FJL-1 shows excellent binding with the 2W9S proteins in terms of docking score compared with the drug Trimethoprim, which also exhibited similar types of interaction and potency against S. aureus. The leaves of F. jangomas can be considered a great source for the identification of numerous important phytoconstituents with potential uses in nutrition, aromatherapy, and the pharmaceutical sector.

Abstract
Fuzhuan brick tea (FBT) is a post-fermented tea fermented by the fungus Eurotium cristatum and is mainly produced in Hunan Province, China. Our previous study revealed that FBT extract prevents obesity by increasing energy expenditure and mitochondrial content in mice. Therefore, in this study, we hypothesized that FBT extract could be effective in alleviating obesity-induced muscle atrophy by addressing mitochondrial dysfunction, and aimed to explore the underlying molecular mechanism of FBT extract in high-fat diet-induced obese mice. FBT extract increased skeletal muscle weight and size, myosin heavy chain isoforms, and muscle performance in obese mice. Additionally, FBT extract reduced obesity-induced intramuscular lipids, skeletal muscle inflammation, and the expression of skeletal muscle atrophy markers, and increased the expression of fibronectin type III domain-containing protein 5 in skeletal muscles. Obesity-induced skeletal muscle mitochondrial dysfunction was improved by FBT extract as analyzed through mitochondrial morphology, fatty acid oxidation, respiratory chain complexes, and mitochondrial dynamics and biogenesis. Epigallocatechin, a major bioactive compound in FBT extract, attenuated palmitic acid-induced muscle atrophy by regulating mitochondrial functions in C2C12 cells. In conclusion, FBT extract may prevent obesity-induced muscle atrophy by alleviating mitochondrial dysfunction in mice.

Cysteine-cysteine Chemokine Receptor Type 5 Plays a Critical Role in Exercise Performance by Regulating Mitochondrial Content in Skeletal Muscle. Inflammation 2023; 46:2089-2101. [PMID: 37436644 DOI: 10.1007/s10753-023-01864-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 06/21/2023] [Accepted: 06/22/2023] [Indexed: 07/13/2023]
Abstract
Cysteine-cysteine chemokine receptor type 5 (CCR5) is thought to play an important role in the trafficking of lymphoid cells but has recently also been associated with AMPK signaling pathways that are implicated in energy metabolism in skeletal muscle. We hypothesized that genetic deletions of CCR5 would alter mitochondria content and exercise performance in mice. CCR5-/- and wild-type mice with the same genetic background were subjected to endurance exercise and grip strength tests. The soleus muscle was stained with immunofluorescence for myosin heavy chain 7 (MYH7) and succinate dehydrogenase (SDH) analysis as well as the expression of genes associated with muscle atrophy and mitochondrial oxidative phosphorylation were measured using qPCR. Although there were no differences in the weight of the soleus muscle between the CCR5-/- group and the wild-type mice, the CCR5-/- mice showed the following muscular dysfunctions: (i) decreased MYH7 percentage and cross-section area, (ii) higher myostatin and atrogin-1 mRNA levels, (iii) dropped expression of mitochondrial DNA-encoded electron respiratory chain genes (cytochrome B, cytochrome c oxidase subunit III, and ATP synthase subunit 6) as well as mitochondrial generation genes (PPARγ and PGC-1α), and (iv) lower SDH activity and exercise performance when compared with wild-type mice. In addition, genes associated with mitochondrial biogenesis (PGC-1α, PPARγ, and MFN2) and mitochondrial complex (ND4 and Cytb) were upregulated when the skeletal muscle cell line C2C12 was exposed to cysteine-cysteine chemokine ligand 4 (a ligand of CCR5) in vitro. These findings suggested that attenuation of endurance exercise performance is related to the loss of mitochondrial content and lower SDH activity of soleus muscle in CCR5 knockout mice. The present study provides evidence indicating that the chemokine receptor CCR5 might modulate the skeletal muscle metabolic energy system during exercise.

Food Sci Biotechnol 2023; 32:381-388. [PMID: 36778088 PMCID: PMC9905349 DOI: 10.1007/s10068-023-01248-7] [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: 09/21/2022] [Revised: 12/01/2022] [Accepted: 01/04/2023] [Indexed: 01/31/2023] Open
Abstract
Commercial whey protein (CWP) is generally produced in the cheese making process with heat treatment. Recently, native whey protein (NWP) can be obtained through microfiltration without heat treatment. The difference in physicochemical properties of CWP and NWP was confirmed in previous studies; however, in vivo research on the effect on muscle strength and protein synthesis is still lacking. In this study, rats were orally administered 1.56 g protein/kg body weight of lyophilized beverages containing CWP and NWP for 8 weeks. The biological value and net protein utilization in the NWP were significantly higher than in the CWP. Moreover, NWP increased muscle mass and grip strength compared to CWP. NWP also increased the phosphorylation of the mammalian target of rapamycin and ribosomal protein S6 kinase, pivotal proteins for muscle protein synthesis. These results suggest that NWP enhance muscle strength and protein synthesis more effectively than CWP.

Abstract
AbstractSarcopenia, characterized by reduced muscle mass and fiber number leading to muscular atrophy, has been associated with serious socioeconomic challenges among the elderly in developed countries. Therefore, preventing sarcopenia could be a promising strategy for achieving a healthy aging society. Nutmeg (Myristica fragrans) has been used as a spice to increase flavor and prevent putrefaction of food. Nutmeg contains various bioactive components that improve muscle activity. To determine the potential effect of lignan-enriched nutmeg extract (LNX) on sarcopenia, LNX (100 mg/kg body weight)-fed aged mice were subjected to forced exercise. Herein, aged (22-month-old) mice fed LNX for three weeks exhibited a shortened and thickened soleus muscle. The ratio of the soleus muscle mass (%) to body weight was significantly increased in LNX-fed aged mice. The relative increase in muscle mass in LNX-fed aged mice improved exercise activities, including rotarod, swimming, and grip strength test results. Proteome profiles of the soleus muscle of LNX-fed mice were used to analyze protein–protein interaction network. Several myosin heavy chain isoforms were found to interact with actin, ACTA1, which functions as a hub protein. Furthermore, the expression of myogenic proteins, such as MYH1, MYH4, and ACTA1, was dose-dependently increased in vivo. In result, our functional proteomic analysis revealed that feeding LNX restored muscle proteins in aged mice.
