RT-qPCR analysis of PDPN mRNA levels in TPC1 thyroid cancer cells 48 h after transfection with 30 nM siRNA specific for PDPN (siPDPN) or a negative control siRNA (siNEG). The results were normalized to the 18S rRNA level and bars represent the average fold change in PDPN transcript abundance in cells transfected with siPDPN compared with cells transfected with siNEG. The results are representative of four independent experiments. Data are presented as the mean ±SEM, **P<0.001. B.

Immunofluorescence staining of podoplanin protein in TPC1 cells transfected with siPDPN and control siNEG. Cells were stained with anti-PDPN monoclonal antibody D2-40 followed by DyLight549-conjugated secondary antibody (red), and counterstained with DAPI (blue). Magnification 1000x. D. Effect of PDPN on cell viability. D, left panel. Proliferation was measured at 24 and 48 h after transfection of TPC1 cells with siPDPN or control siNEG. Cells seeded in 96-well plates were treated with XTT mixture reagent and formazan formation was measured at 450 nm to determine the number of viable cells. Data are expressed as the mean ±SEM of at least three independent experiments performed in quintuplicate. D, right panel. Apoptosis was measured at 48 h after transfection of TPC1 cells with siPDPN or control siNEG. Cells were collected and stained with FITC Annexin V and propidium iodide, followed by flow cytometry. Representative measurements of the percentage of Annexin V+ cells are presented. Each bar represents the mean ±SEM of at least three independent experiments performed in quadruplicate. E. Function of podoplanin in cell adhesion. TPC1 cells transfected with siPDPN display adhesion capacity comparable to those of siNEG-transfected cells. Briefly, 8000 transfected cells were seeded in the wells of 96-well plates. After incubation for 24 or 48 h, the cell monolayers were washed, fixed with 4% formaldehyde for 15 min and stained with crystal violet (Merck, USA). The stained cells were lysed by treatment with 2% SDS, then the intensity of the released stain was quantified by spectrophotometry at 550 nm using a Labsystems Multiscan RC microplate reader (Thermo Fisher Scientific, Canada). Data represents three separate experiments.

    • Mouse anti human podoplanin antibody, clone D2-40 was raised against M2A antigen (Marks et al, 1999) and detects podoplanin (Sonne et al, 2006). Podoplanin (PDPN) is an O-glycosylated transmembrane glycoprotein that is selectively expressed by, and is a marker of, lymphatic endothelial cells. In normal tissue the 38 kDa protein is also present in human lung, placenta, heart, skeletal muscle and kidney podocytes. It is not found in the blood vasculature (Breiteneder-Geleff et al, 1999, Wicki and Christofori, 2007).

      The function of podoplanin is yet to be fully elucidated; however, it may be involved in cell migration and/or actin cytoskeleton organization. It is required for normal lung cell proliferation and alveolus formation at birth, and can induce platelet aggregation (Ramirez et al, 2003, Wicki and Christofori, 2007).

      Mouse anti human podoplanin antibody, clone D2-40 has been shown to be a sensitive and specific antibody for the detection of lymphatic endothelium in different malignancies, and is of value in the routine evaluation of lymphatic invasion in esophageal cancer (Kozłowski et al, 2011). Clone D2-40 was reported to be an excellent immunohistochemical marker of cutaneous Kaposi’s sarcomas, (Kahn et al, 2002), and may be useful in the differential diagnosis of epithelioid malignant mesothelioma versus adenocarcinoma (Chu et al, 2005).
