Sphinganine alleviates sepsis-induced intestinal injury in vitro. (A) Effect of a 24 h treatment with mannose-6-phosphate (10μm) and sphinganine (10μm) on Caco-2 cell cytotoxicity, as evidenced by the LDH assay. (B) Chemical structure of sphinganine. (C) Outcome of 24 h treatments with varying sphinganine concentrations on Caco-2 cell cytotoxicity, as evidenced by the LDH assay. (D) ZO-1 and occludin protein expressions, as assessed by Western blot analysis. (E) Statistical plot of gray value of ZO-1 and Occludin were detected by Western blot. P values 0.05 (*) or 0.01 (**) was regarded as significant.
