Lasts. C2C12 cells have been treated with PA (one hundred ), probably the most abundant dietary SFA, for 24 h then differentiated up to 5 days. Myoblast differentiation was then evaluated according to the myogenic variables expressions and myotube formation. PA-treatment remarkably decreased the MyHC-positive area and suppressed myoblast differentiation and fusion in C2C12 cells as determined by immunocytochemistry and quantitative image analysis (Figure 1A,B). In agreement with immunocytochemistry findings, PA significantly suppressed the levels of MyoD, MyoG, and MyHC (Figure 1C), indicating that PA drastically impeded myogenic aspects expressions and differentiation in C2C12 myoblasts. Interestingly, beneath these conditions, the expression of CFL2 was drastically diminished by PA (Figure 1C,D). These final results recommend that impaired myogenic differentiation by PA is linked with CFL2 suppression in myoblasts. Next, we investigated regardless of whether precise miRNAs upregulated by PA are implicated in CFL2 suppression in myoblasts. In accordance with microarray benefits, the expression of miR-325-3p, which was predicted to target 3 UTR of CFL2 with a higher probability in line with the miRNA target analysis working with TargetScan and miRWalk, was upregulated 1.5-fold in PA-treated myoblasts (Supplementary Information). Hence, miR-3253p was selected for further investigation since it has been supposed to become connected with muscle atrophy and dystrophy [29,30]. The qRT-PCR confirmed that PA raised miR-3253p expression in myoblasts by PF 05089771 In Vivo 3-fold (Figure 1E). Collectively, PA was identified to impair myogenic differentiation and suppress CFL2 expression but induce miR-325-3p expression in myoblasts.Cells 2021, 10, 2725 Cells 2021, 10, x FOR PEER REVIEW5 of 14 5 ofFigure 1.
