Abstract
Probiotics are used in pigs as nutritional supplements to improve health and induce the development of muscle and adipose tissue for enhancing growth performance and harvesting quality meat. In this study, we investigated the effects of Bacillus-based probiotic supplementation on the physiological and biochemical changes in Jeju native pigs (JNPs), including growth performance, backfat layers, blood parameters, serum IgG levels, myogenic and adipogenic markers, and expression of inflammatory markers. Average daily gain and feed efficiency were higher in the Bacillus diet group than in the basal diet group, while backfat thickness was lower in the Bacillus diet group than in the basal diet group. Blood biochemical parameters and hematological profiles were not altered significantly by Bacillus-based probiotic supplementation. Serum IgG concentration increased in the Bacillus diet group compared to the basal diet group. The Bacillus diet group showed increased adipogenic and myogenic markers expression in the longissimus dorsi muscle and adipose tissues. Overall, the data suggest that the Bacillus-based probiotics-supplemented diet regulates myogenesis and adipogenesis in JNPs and improves growth performance. We postulate that this may be due to the changes in the gut microbiota of pigs due to probiotic supplementation.

Abstract
BACKGROUND Perivascular epithelioid cell tumors (PEComa)s are mesenchymal neoplasms located at various anatomic sites, which usually express both melanocytic and myogenic markers. CASE REPORT A 60-year-old woman underwent laparotomy for a huge, heterogeneous, right ovarian mass. The histological examination of the surgical specimen revealed a neoplasm consisting of both cells with clear or eosinophilic cytoplasm and spindle cells in a myxoid stroma. Immunostaining was positive for human melanoma black-45, h-caldesmon, desmin, actin, and transcription factor 3. Cell atypias were moderate, mitoses were 4/10 high power fields (HPF) and margins were focally infiltrative. These findings pointed to a diagnosis of ovarian PEComa. Twenty-five months later, two subcutaneous lesions were surgically removed on the left trapezius muscle and the median subumbilical area, respectively. The former was a desmoid fibromatosis, whereas the latter was a recurrence of PEComa with greater nuclear pleomorphism and higher number of mitoses (26/50 HPF) compared to the primary tumor. The patient was free of disease 11 months later. CONCLUSION A long-term follow-up of gynecological PEComas is strongly recommended.

Abstract
The proliferation and differentiation of skeletal muscle satellite cells (SMSCs) play an important role in the development of skeletal muscle. Our previous sequencing data showed that miR-21-5p is one of the most abundant miRNAs in chicken skeletal muscle. Therefore, in this study, the spatiotemporal expression of miR-21-5p and its effects on skeletal muscle development of chickens were explored using in vitro cultured SMSCs as a model. The results in this study showed that miR-21-5p was highly expressed in the skeletal muscle of chickens. The overexpression of miR-21-5p promoted the proliferation of SMSCs as evidenced by increased cell viability, increased cell number in the proliferative phase, and increased mRNA and protein expression of proliferation markers including PCNA, CDK2, and CCND1. Moreover, it was revealed that miR-21-5p promotes the formation of myotubes by modulating the expression of myogenic markers including MyoG, MyoD, and MyHC, whereas knockdown of miR-21-5p showed the opposite result. Gene prediction and dual fluorescence analysis confirmed that KLF3 was one of the direct target genes of miR-21-5p. We confirmed that, contrary to the function of miR-21-5p, KLF3 plays a negative role in the proliferation and differentiation of SMSCs. Si-KLF3 promotes cell number and proliferation activity, as well as the cell differentiation processes. Our results demonstrated that miR-21-5p promotes the proliferation and differentiation of SMSCs by targeting KLF3. Collectively, the results obtained in this study laid a foundation for exploring the mechanism through which miR-21-5p regulates SMSCs.

Abstract
Vitamin D (VD) deficiency is associated with musculoskeletal disorders. This study examines whether co-supplementation of l-cysteine (LC) and VD is better than monotherapy with LC or VD at alleviating musculoskeletal dyshomeostasis in the skeletal muscle of VD-deficient high-fat diet (HFD-VD-) fed mice. Mice were fed a healthy diet or an HFD; for VD-deficient animals, the mice were maintained on a HFD-VD-diet (16 weeks); after the first 8 weeks, the HFD-VD-diet-fed mice were supplemented for another 8 weeks with LC, VD-alone, or the same doses of LC + VD by oral gavage. Saline and olive oil served as controls. Myotubes were exposed with high-glucose, palmitate, Monocyte Chemoattractant Protein 1 (MCP-1), and Tumor Necrosis Factor (TNF), to mimic the in vivo microenvironment. In vitro deficiencies of glutathione and hydrogen sulfide were induced by knockdown of GCLC and CSE genes. Relative gene expression of biomarkers (myogenic: MyoD, Mef2c, Csrp3; muscle dystrophy: Atrogin1, Murf1, and Myostatin; bone modeling and remodeling: RANK, RANKL, OPG) were analyzed using qRT-PCR. Co-supplementatoin with LC + VD showed beneficial effects on gene expression of myogenic markers and OPG but reduced markers of dystrophy, RANK/RANKL in comparison to LC or VD alone-supplementation. In vitro myotubes treated with glutathione (GSH) precursors also showed a positive effect on OPG and the myogenesis genes, and inhibited RANK/RANKL and muscle-dystrophy markers. This study reveals that the co-supplementation of LC with VD significantly alleviates the markers of musculoskeletal disorders in the skeletal muscle better than monotherapy with LC or VD in HFD-VD-fed mice.
