Article Title: Leucine promotes differentiation of porcine myoblasts through the protein kinase B (Akt)/Forkhead box O1 signalling pathway

doi: 10.1017/s0007114518000181

Figure Lengend Snippet: Fig. 3. Leucine activates the protein kinase B (Akt)/Forkhead box O1 (FoxO1) pathway during porcine myoblast differentiation. When the cells reached approximately 80 % confluence, porcine myoblasts were induced to differentiate with medium containing different concentrations of leucine for 3 d. Akt, phosphorylated Akt (P-Akt), phosphorylated FoxO1 (P-FoxO1) and FoxO1 protein levels were determined by Western blot analysis. Equal loading was monitored with anti-glyceraldehyde-3- phosphate dehydrogenase (GAPDH) antibody. Mean values with their standard errors of the densitometry results from three independent experiments are shown in the lower panel. ** P < 0·01, *** P < 0·001 as compared with negative control.

doi: 10.3390/cells11071122

Figure Lengend Snippet: FOXO1 increases in alveolar epithelial cells as a function of time in culture, and knockdown increases expression of the AT2 cell-specific marker SFTPC. Representative Western blot (WB) ( A ) and quantitation ( B – D ) show that the expression of FOXO1, but not FOXO3 and FOXO4, increases as rat AT2 cells (D0) differentiate into AT1-like cells at day eight (D8) in primary culture. EIF-4E, EIF-2α, and β -ACTIN were the loading controls. n = 4 for each group. One-way ANOVA, asterisk indicates p < 0.05 compared to D0. Representative WB ( E ) and quantitation ( F , G ) show that knockdown of FOXO1 increased pro-SFTPC expression in primary AEC six days following transduction with FoxO1 shRNA (+) or non-silencing shRNA (−) on Day two. EIF-2α was used as the loading control. The data were normalized to non-silencing shRNA. n = 4 for each group. Unpaired two-tailed t -test, asterisk indicates p < 0.05.

Figure Lengend Snippet: FOXO1 attenuates NKX2.1 activation of SFTPC and SFTPB . ( A ) MLE-15 cells were co-transfected with a 3.7 kb SFTPC reporter construct (3.7- SFTPC -Luc) and NKX2.1 or FOXO1 expression constructs alone or in combination. Dual luciferase assays 48 h following transduction showed that FOXO1 inhibited NKX2.1 activation of the SFTPC reporter. Firefly luciferase activity was normalized to Renilla luciferase. n = 4 for each group. One-way ANOVA, asterisk indicates p < 0.05. ( B ) MLE-15 cells were co-transfected with 3.7- SFTPC -Luc, pRC/CMV/ NKX2.1 and increasing concentrations of FOXO1 expression construct. Dual luciferase assays 48 h post-transduction showed that FOXO1 inhibited NKX2.1-mediated induction of the SFTPC reporter in a dose-dependent manner. The data are shown as normalized to the absence of FOXO1. n = 4 for each group. One-way ANOVA, asterisk indicates p < 0.05 compared to absence of FOXO1 (empty vector).

Dual luciferase assays 48 h post-transduction showed that FOXO1-H215R maintained the ability to repress NKX2.1 activation of the SFTPC reporter. Firefly luciferase activity was normalized to Renilla luciferase. The data are shown as normalized to the absence of FOXO1 and NKX2.1. n = 3 for each group.

Figure Lengend Snippet: FOXO1 repressor function is negatively regulated by PI-3K-dependent phosphorylation. ( A ) MLE-15 cells were co-transfected with the 3.7-SFTPC-Luc reporter construct, NKX2.1 expression construct and FOXO1 or FOXO1-AAA, a dephosphorylated constitutively active form of FOXO1.

( C ) MLE-15 cells were co-transfected with a 3.7-SFTPC-Luc reporter construct and NKX2.1 expression construct for 24 h, followed by treatment with Ly294002 (1 µM) for an additional 24 h. Dual luciferase assay showed that Ly294002 inhibited SFTPC reporter activity. The data are shown as normalized to the absence of both NKX2 and Ly294002. n = 3 for each group. One-way ANOVA, asterisk indicates p < 0.05.

doi: 10.3390/cells11071122

Figure Lengend Snippet: Model of mechanisms underlying FOXO1 regulation of lung-specific NKX2.1-activated genes via PI-3K/AKT-dependent phosphorylation. In AT2 and AT2-like cells in the presence of KGF, the PI-3K/AKT pathway is activated, leading to downstream phosphorylation of FOXO1 and subsequent cytoplasmic extrusion and degradation. The absence of nuclear FOXO1 allows active NKX2.1 to remain at the SFTPC and SFTPB promoters, increasing the expression of these AT2 cell-specific target genes. During the transition from AT2 to AT1-like cells (AT1.5 intermediate cells), or in the absence of KGF, the PI-3K/AKT pathway becomes inactivated. This in turn prevents the phosphorylation of FOXO1, allowing it to remain in the nucleus and interact with and pull NKX2.1 from its target promoters. This process is completed in differentiated AT1-like cells, where NKX2.1 removal from target genes by FOXO1 leads to the inhibition of gene expression.
