Ceramides Mixture 是表皮渗透屏障的主要脂质成分，参与生长抑制，细胞周期停滞和端粒酶活性的调节。它是一种内源性神经酰胺，由含羟基和非羟基脂肪酸的神经酰胺组成。

Ceramides Mixture, an endogenous ceramide, consists of hydroxy and non-hydroxy fatty acid-containing ceramides. It is involved in the regulation of cell cycle arrest, growth inhibition, and modulation of telomerase activity.

Endogenous Ceramides inhibits mRNA synthesis of telomerase reverse transcriptase and telomerase activity via inactivation of the c-Myc transcription factor in the A549 human lung adenocarcinoma cell line. The sustained generation of long-chain endogenous ceramide requires the biochemical recycling of the sphingosine backbone of C6-ceramide, which involves deacylation and reacylation of ceramide for the generation of endogenous long-chain ceramide, most likely by CoA-dependent ceramide synthase, which is inhibited by fumonisin B1. In A549 cells the generation of long-chain endogenous ceramide mediates the effects of exogenous C6-ceramide on growth inhibition, cell cycle arrest, and the modulation of telomerase activity [1].
