Upregulated estrogen receptors impairs myogenesis and elevates adipogenesis related factor levels in the paravertebral muscles of patients with idiopathic scoliosis. Biochem Biophys Res Commun 2023; 652:22-30. [PMID: 36806085 DOI: 10.1016/j.bbrc.2023.02.034] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 02/14/2023] [Accepted: 02/14/2023] [Indexed: 02/18/2023]
Abstract
The prevalence of idiopathic scoliosis (IS) is 2-3% worldwide and is more common in girls. Estrogen receptors (ERs) is supposed to be related to sex differences and development of IS. Meanwhile, paravertebral muscle (PVM) abnormalities play important roles in the pathogenesis of IS. But the changes of ERs between the PVMs from IS patients and controls, and the mechanism by which ERs may affect IS patients remain unclear. Thus, the expression levels of ERs, myogenesis regulator (MYOG) and adipogenesis related factors (CEBPA, PPARγ, FABP4), as well as morphological changes in the PVMs and primary skeletal muscle mesenchymal progenitor cells (hSM-MPCs) of IS patients and controls were investigated. Increased expression levels of ERs and CEBPA, PPARγ, FABP4, together with severe myofiber necrosis and fat infiltration, were found in the PVMs of IS patients. Meanwhile, upregulated ERs, FABP4 and CEBPA, downregulated MYOG and impaired myogenesis were also revealed in the hSM-MPCs of IS patients compared with those of controls. Upregulation of ERs inhibited myogenesis but increased expression of CEBPA and FABP4 in C2C12 myoblasts. Nevertheless, treatment of ER antagonist increased expression of MYOG, enhanced myogenesis and decreased expression of CEBPA and FABP4 in skeletal muscle cells of IS patients. Therefore, our study suggested that PVMs specific upregulation of ERs could impair myogenesis and increase the expression of adipogenesis related factors, further leading to PVMs abnormalities in IS patients.

[PMID: 36496566 PMCID: PMC9738036 DOI: 10.3390/foods11233755] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 11/18/2022] [Accepted: 11/21/2022] [Indexed: 11/23/2022] Open
Abstract
Cultured meat is an emerging technology for manufacturing meat through cell culture rather than animal rearing. Under most existing culture systems, the content and maturity of in vitro generated myotubes are insufficient, limiting the application and public acceptance of cultured meat. Here we demonstrated that a natural compound, naringenin (NAR), promoted myogenic differentiation of porcine satellite cells (PSCs) in vitro and increased the content and maturity of generated myotubes, especially for PSCs that had undergone extensive expansion. Mechanistically, NAR upregulated the IGF-1/AKT/mTOR anabolic pathway during the myogenesis of PSCs by activating the estrogen receptor β. Moreover, PSCs were mixed with hydrogels and cultured in a mold with parallel micro-channels to manufacture cultured pork samples. More mature myosin was detected, and obvious sarcomere was observed when the differentiation medium was supplemented with NAR. Taken together, these findings suggested that NAR induced the differentiation of PSCs and generation of mature myotubes through upregulation of the IGF-1 signaling, contributing to the development of efficient and innovative cultured meat production systems.
