GSE90051 described hub gene expression in keloid vs. adjacent non-lesion skin tissues and its evaluation confirmed the changes in the expression of the lipo-related hub genes ABHD5, ADIPOQ, CIDEC, DGAT2, FABP4, LEP, LPL, PDK4, PLIN1, PPARG, and PPARGC1A, as well as lncRNAs HOTAIR and PART1 in these tissues (Figure 3A). The gene discussed is LEP; the disease is keloid.
