Effect of 1-Glc and Ac-1-Glc compared
to PF-543 in TGFβ1-induced fibrosis marker expression
in murine myoblasts. C2C12 myoblasts were seeded to 80% confluence
and treated with 5.0 ng/mL TGFβ1, PF-543, 1-Glc, and Ac-1-Glc (30 min, 120 min). (A) The
expression of protein markers, which expression correlates with muscle
fibrosis, has been evaluated by Western blot analysis, using specific
anti-α-SMA and anti-SMα22. A representative blot is shown
among three independent experiments with analogous results. (B and
C) Densitometric analysis was performed of three independent experiments
and data, normalized to β-actin expression, were reported as
mean ± SD of fold change above control untreated. The effect
of pharmacological inhibition of SK1 on TGFβ1 induced fibrosis
marker expression was significant by two-way ANOVA followed by Bonferroni posthoc test. #P < 0.05, ##P < 0.01, ###P < 0.001. The effect of pharmacological
inhibition of SK1 by 30 min Ac-1-Glc compared to 1-Glc on TGFβ1 induced αSMA expression was significant
by two-way ANOVA followed by Bonferroni posthoc test.
