The latest integrated single-cell RNA-sequencing analysis revealed that the overexpression of FABP1 is a novel biomarker of poor prognosis in patients with GC and is involved in the peroxisome proliferator-activated receptors (PPAR) signaling pathway, hormone-sensitive lipase-mediated triacylglycerol hydrolysis, and fat digestion and absorption (Yang et al., 2022a). The gene discussed is PPARA; the disease is gastric cancer.
