TSC2 and lymphangioleiomyomatosis: Priolo et al. [93] revealed that fifteen lipid species were overexpressed in plasma of LAM patients (p<0.05), including nine triacylglycerol, two phosphatidylcholines, and four lysophosphatidylcholines (LPC) species (C16:0, C18:0, C18:1, and C20:4), and also 43 lipid species were abnormal in the TSC2− cells (p<0.05) compared with TSC2+ cells.
