“…This suggests a mechanism by which 1α,25(OH) 2 D 3 activates AKT by downregulating PP2A and inhibiting the expression of ubiquitin ligases. This inhibition of PP2A may have a non-genomic effect because there are reports that 1α,25(OH) 2 D 3 combined with vitamin D receptor (VDR) non-genomically activates MAPK, Src, and AKT (8,9). The addition of 1α,25(OH) 2 D 3 has been shown in our microarray analysis to inhibit β-catenin that is involved in the Wnt signaling pathway.…”

“…Vitamin D 3 seems to act as a multifunctional regulator in skeletal muscle. During proliferation and differentiation, 1α,25(OH) 2 D 3 upregulates AKT, Src and p38 mitogen-activated protein kinase (p38 MAPK), and thereby stimulates proliferation, survival, and differentiation of skeletal muscle cells (C2C12) (8). Suppression of differentiation and promotion of hy- , which are reported to be profoundly involved in inflammatory processes via autocrine, paracrine, and endocrine pathways (32).…”

“…Предпо-лагается, что VDR экспрессируется в очень низких ко-личествах в покоящихся мышцах, а активация экспрес-сии происходит в определенных условиях, например, при стрессе. Исследование на моделях, использующих животных различного возраста, предполагает измене-ние экспрессии с возрастом и различную роль VDR в раз-вивающейся и зрелой мышечной ткани [81]; при воз-действии витамина D показано повышение экспрессии VDR в мышечной ткани человека [82], а также быстрые, нетранскрипционные эффекты в мышиной скелетной мускулатуре [83]. Предстоит определить, вызваны ли эффекты витамина D напрямую активацией VDR или опо-средованы изменениями абсорбции кальция, влияющи-ми на секрецию ПТГ и на внутриклеточные уровни каль-ция [61].…”

“…Il a été montré dans des myotubes en culture que cette voie gé-nomique a une influence sur l'absorption et les flux calciques cellulaires, en particulier sa capture post-contraction par le ré-ticulum sarcoplasmique et le transport du phosphate à travers la membrane cellulaire. D'autres études ont rapporté que la vitamine D, via son action génomique, contribue au contrôle de la prolifération cellulaire et de la différenciation en fibres musculaires matures (Boland, 1998(Boland, , 2011Buitrago, 2012Buitrago, , 2013Costa, 1986). Il faut noter que les modifications des taux calciques intracellulaires induites par la vitamine D semblent moduler la contraction et la relaxation myofibrillaires, affectant ainsi la fonction contractile de ce tissu (Boland, 1995 ;Ebashi, 1968).…”
