The staining of Orai3 was low in non-tumour lung, and in invasive predominant lepidic and papillary adenocarcinoma (Figure 1C–1D), was moderate in infiltrating acinar adenocarcinoma (Figure 1E), and high in infiltrating solid adenocarcinoma (Figure 1F). This evidence concerns the gene ORAI3 and papillary adenocarcinoma.
