Characterization of human PA2.26 antigen (T1α-2, podoplanin), a small membrane mucin induced in oral squamous cell carcinomas: PA2.26 Antigen and Oral Squamous Cell Carcinoma
Open accessAbstract
We report the full cDNA sequence encoding the human homologue of murine PA2.26 (T1alpha-2, podoplanin), a small mucin-type transmembrane glycoprotein originally identified as a cell-surface antigen induced in keratinocytes during mouse skin carcinogenesis. The human PA2.26 gene is expressed as 2 transcripts of 0.9 and 2.7 kb in several normal tissues, such as the placenta, skeletal muscle, heart and lung. Using a specific polyclonal antibody raised against a synthetic peptide of the protein ectodomain, PA2.26 was immunohistochemically detected in about 25% (15/61) of human early oral squamous cell carcinomas. PA2.26 distribution in the tumours was heterogeneous and often restricted to the invasive front. Double immunofluorescence and confocal microscopy analysis showed that PA2.26 colocalized with the membrane cytoskeleton linker ezrin at the surface of tumour cells and that its presence in vivo was associated with downregulation of membrane E-cadherin protein expression. Ectopic expression of human PA2.26 in HeLa carcinoma cells and immortalized HaCaT keratinocytes promoted a redistribution of ezrin to the cell edges, the formation of cell-surface protrusions and reduced Ca(2+)-dependent cell-cell adhesiveness. These results point to PA2.26 as a novel biomarker for oral squamous cell carcinomas that might be involved in migration/invasion.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
