Among them, ARF1 was significantly overexpressed in 26 cancers (Fig. 1A); ARF3 was significantly overexpressed in 26 cancers and only low in glioblastoma multiforme (Fig. 1B); ARF4 was significantly overexpressed in 26 cancers (Fig. 1C); ARF5 was significantly overexpressed in 28 cancers and only low expressed in esophageal carcinoma (Fig. 1D); ARF6 was significantly overexpressed in 23 cancers, while it was low expressed in esophageal carcinoma and skin cutaneous melanoma (Fig. 1E). This evidence concerns the gene ARF3 and carcinoma of esophagus.
