After treatment with radiation, the A2780wtTP53 cells demonstrated a 3.6-fold increase at 24 h while the A2780m TP53 cells had a 4.5-fold increase at 24 h and a 9.5-fold increase at 48 h.

Figure Lengend Snippet: Possible mechanisms of TP53 regulation of THBS1 expression . Wild-type (wt) TP53 may bind to the THBS1 promoter resulting in gene transcription. Alternatively, wt TP53 is normally degraded and expressed at low levels allowing for a secondary factor to bind to the promoter site. Missense p53 protein can bind with wt p53 protein and prevent it from forming homotetramers and/or interacting with DNA, or if it does interact with DNA, the presence of the mutant protein may impede interaction with other secondary factors required to drive induction of transcription. In rare cases, upon mutation the wt p53 DNA-binding activity is lost and the p53 target regions are vulnerable to de novo cytosine methylation (Me) that inhibits transcription. Null TP53 mutations lead to complete loss of function of the gene and abnormal p53 fragments that are degraded. This may allow for a secondary factor to bind and induce THBS1 transcription.

Figure Lengend Snippet: A, FVB/n mice (n = 4) exercised for 1 day or remained sedentary (S). Muscles were extracted immediately (Ex), or 2 h after training (Ex+2 h). B, FVB/n FoxOL/L mice (n = 6) trained for 1, 7, 10 or 14 days (D1, D7, D10, D14) or remained sedentary (S), and all muscles were extracted 2 h after the final training session. In both, THBS1 protein was assessed relative to β-actin. For densitometric analysis of THBS1, intensities of the three bands evident at ∼ 175 kDa were summed together. *P < 0.05 vs. sedentary; ##P < 0.01 vs. Ex (Tukey post hoc analysis).

doi: 10.1113/jphysiol.2014.275867

Figure Lengend Snippet: A, FoxO1 and FoxO3a protein levels were analysed in endothelial cells isolated from epididymal fat of FoxOL/L and FoxOΔ mice (n = 3). Representative blots are shown, with the respective densitometric values (relative to β-actin) listed under each blot. B, muscles were extracted from FoxOL/L and FoxOΔ sedentary (S) mice, or 2 h after an acute exercise bout (D1). FoxO1 and FoxO3a protein levels were assessed by Western blot to determine the extent of deletion from whole gastrocnemius extracts, and quantified relative to tubulin. Significant exercise and genotype effects were observed (two-way ANOVA) for both FoxO1 (P = 0.0008 and P = 0.006, respectively) and FoxO3a (P = 0.01 and P = 0.009, respectively). C, FoxOL/L and FoxOΔ mice (n = 6) trained for 1, 7 or 14 days, or remained sedentary (S) and muscles were extracted 2 h after training. THBS1 mRNA levels were measured by qPCR, normalizing to the housekeeping gene HPRT. Significant training (P < 0.0001) and genotype (P < 0.01) effects were observed (two-way ANOVA). D, THBS1 protein was assessed by Western blot of whole gastrocnemius extracts and quantified relative to tubulin. Significant exercise (P < 0.05) and genotype (P < 0.05) effects were observed (two-way ANOVA). *P < 0.05; ***P < 0.001 vs. sedentary FoxOL/L; #P < 0.05; ##P < 0.01; ###P < 0.001 vs. FoxOΔ day 1 (Bonferroni post hoc analysis).
