ARPC5 and pancreatic neoplasm: High expression of ARPC5 was significantly positively related to 43 gene sets at FDR <0.01, and the following pathways might be involved in tumor development and pathogenesis: the “MAPK signaling pathway,” “non–small-cell lung cancer,” “small-cell lung cancer,” “pancreatic cancer,” the “WNT signaling pathway,” and the “toll-like receptor signaling pathway” (Figure 13C).
