Expression of MarvelD3 isoforms in different epithelial and endothelial cells. Reverse transcription PCR was used to analyse the expression of MarvelD3 isoforms in cultured human epithelial and endothelial cells (A) and adult mouse tissues (B). Primers were used to specifically amplify MarvelD3 isoforms or, as a control, GAPDH. In panel A, cell lines and primary cultures derived from the following cell types were used: Caco-2, colon adenocarcinoma cells; HCE, immortalised corneal epithelial cells; PNT-1a and PNT2-C2, immortalised prostate epithelial cells; HepG2, hepatocellular carcinoma cells; HaCaT, spontaneously immortalised skin keratinocytes; ARPE-19, spontaneously immortalised retinal pigment epithelial cells; hCMEC/D3, immortalised brain endothelial cells; HCEC-B4G12, immortalised corneal endothelial cells; HUVEC, umbilical vein endothelial cells. Note, mRNAs for both isoforms are widely expressed by epithelial and endothelial cells.
