High S6, LDHA and CPT1A and, additionally, lower FASN and GLS mRNA expression were associated with worse prognosis in luminal breast cancer types (KM-plotter—Table S2), similarly to our results for survival and the protein-level expression of p-S6, LDHA, CPT1A, FASN and GLS in tumour tissues. Here, FASN is linked to neoplasm.
