Lipidomic analysis of DDLPS and WDLPS. (A) PCA score plot of DDLPS and WDLPS. Each green circle represents a WDLPS sample, and each blue triangle represents a DDLPS sample. (B) Volcano plot showing the number of significantly changed lipids between the two subtypes of tumors, and the top 20 altered lipids are labeled. (C) Expression Profile and VIP of metabolites between DDLPS and WDLPS; * P < 0.05, ** P < 0.01, and *** P < 0.001. (D) The significantly changed lipids enriched in the KEGG pathway between WDLPS and DDLPS; ** P < 0.01, and *** P < 0.001; n = 9 for the WDLPS group and n = 11 for the DDLPS group
