Additionally, the lncRNA BARD1 9′L, which stimulates the expression of BARD1-FL and isoforms β, δ, and γ through interaction with the 3′ UTR of BARD1, was significantly upregulated in lung tumors compared to paired cancer-free lung tissue as well as in the human lung adenocarcinoma cell line, A549 [103]. This evidence concerns the gene BARD1 and lung adenocarcinoma.
