Among those gene lists, enzymes involved in the mevalonate pathway, which mainly synthesize sterols as end-products, including farnesyl-diphosphate farnesyltransferase 1, farnesyl diphosphate synthase (FDPS), and 3-hydroxy-3-methyglutaryl-CoA synthase 1, were highly upregulated when compared to differentiated glioblastoma cells [96]. The gene discussed is FDPS; the disease is glioblastoma.
