Lasts. C2C12 cells were treated with PA (one hundred ), probably the most abundant dietary SFA, for 24 h after which differentiated as much as 5 days. Myoblast differentiation was then evaluated in accordance with the myogenic aspects 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 D-Luciferin potassium salt web Quantitative image analysis (Figure 1A,B). In agreement with immunocytochemistry findings, PA substantially suppressed the levels of MyoD, MyoG, and MyHC (Figure 1C), indicating that PA substantially impeded myogenic variables expressions and differentiation in C2C12 myoblasts. Interestingly, under these conditions, the expression of CFL2 was considerably diminished by PA (Figure 1C,D). These outcomes suggest that impaired myogenic differentiation by PA is linked with CFL2 suppression in myoblasts. Subsequent, we investigated whether distinct miRNAs upregulated by PA are implicated in CFL2 suppression in myoblasts. As outlined by microarray benefits, the expression of miR-325-3p, which was predicted to target 3 UTR of CFL2 with a high probability based on the miRNA target evaluation applying TargetScan and miRWalk, was upregulated 1.5-fold in PA-treated myoblasts (Supplementary Information). For that reason, miR-3253p was chosen for further investigation since it has been supposed to be related with muscle atrophy and dystrophy [29,30]. The qRT-PCR confirmed that PA raised miR-3253p expression in myoblasts by 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.
