The FAO was prompted to support chemoresistance and stemness of gastric cancer cells when HCP5 sequestered miR-3619–5p and upregulated peroxisome proliferator activated receptor gamma coactivator 1 alpha (PPARGC1A), enhancing the transcription complex PPAR coactivator 1 (PGC1)/CCAAT enhancer binding protein (CEBPB), and transcriptionally inducing CPT1 [138]. The gene discussed is PPARGC1A; the disease is gastric cancer.
