Other Vav2/Vav3-dependent (Areg, Hbegf) and -independent (Egf, Btc [ID number: 12223]) transcripts displayed similar levels in papillomas regardless of the Vav2/Vav3 expression status, further suggesting that the autocrine/paracrine defect was ameliorated in these tumors (Figure 8A). This evidence concerns the gene VAV2 and papilloma.
