PLIN1 and neoplasm: Notably, higher expression of several genes coding for proteins involved in cellular lipid metabolism, e.g., FABP4, IGF1, IGF2, LEP, TUSC5, CIDEA, HSPB6, LIPE, PLIN4, PLIN1 ADH1B, and ADH1C were seen in CAV1-high tumors, supporting a potential association with altered tumor metabolism.
