Mechanism of modulation on sphingolipids by silibinin (A), xanthohumol (B) and Res (C). modulation on sphingolipids by silibinin (A), xanthohumol (B) and Res (C). It is actually depicted with an asterisk () enzymatic pathway, with plus (+) red-regulated pathway and with (- down-regulation ones. minus (-))down-regulation ones.In agreement with Lim et al. [112], Tiang et al. [113] proposed Res to become an apoptotic agent in the myelogenous leukemia cell line K562 by modulation of SphK1 and translocation from the enzyme from the membrane to the cytosol. The kinase activity is clearly repressed granting a restoration of L-Palmitoylcarnitine Epigenetic Reader Domain sphingolipid balance. Sph-1P level decreases whereas Cer level increases. Cakir et al. [114] showed that Res induces apoptosis via a concurrent increase of de novo Cer and lower of anti-apoptotic Sph-1P and GlcCer. Not only, targeting Cer metabolism improved chemosensitivity to Res in acute myeloid leukemia cells. Kartal’s study [115] was also focused on the connection between the sphingolipid pathway, Res and human K562 chronic myeloid leukemia cells. A synergistic anti-proliferative effect was observed with Res in combination with: (1) Cer-C8, a cell-permeable analog of natural Cer inducing de novo generation; (two) PDMP, an inhibitor of GlcS; and (3) PF-543, a SphK1 inhibitor. In addition, they showed that Res triggers apoptosis via raising expression of longevity assurance genes (LASS2, LASS4, LASS5, LASS6) correlated with down-regulation of GlcS and SphK 1. Chow et al. [116] reported an abnormal accumulation of Cer by way of activation of SPT resulting in an ER dilation/expansion and thus ER anxiety. ER tension is, indeed, firmly related with cell apoptosis by mechanisms involving direct activation of ER-associate caspases (three, 9 and 12) and CHOP, a typical downstream pro-apoptotic molecule of unfolded protein response. Wang et al. [117] described two divergent mechanisms of Res in melanoma B16 cells. They showed an inhibition of B16 cell growth via induction of mitochondrial apoptosis and modern inducing protective autophagy via Cer accumulation and AKT/mTOR pathway inhibition. Interruption with the autophagy system leads to an improvement of your efficacy of Res cytotoxicity and apoptosis. It was the first study revealing that Res-induced accumulation of Cer conferred protection of B16 cells against apoptosis inducing protective autophagy. A further mechanism was proposed according to Mizutani et al. [118]. Inhibition in K562 (a human leukemia cell line) and HTC116 (a human colon cancer cell line) by Res was correlated to up-regulationNutrients 2018, ten,17 ofof Cer and aSMase expression and down-regulation of Sph-1P. This study suggested a feasible relationship among Res-induced cell growth inhibition plus the sphingolipid metabolism modulation. As previously talked about, catechin.
