Podoplanin (PDPN), also known as Aggrus or T1-alpha, is a transmembrane glycoprotein critically involved in cell migration, platelet aggregation, and lymphatic vascular development. It mediates cellular effects by binding to C-type lectin-like receptor 2 (CLEC-2) on platelets, triggering downstream signaling through Syk/SLP-76 and PI3K/AKT pathways, which regulate cytoskeletal reorganization and metastatic dissemination. PDPN is overexpressed in multiple cancers, including glioblastoma, squamous cell carcinoma, and melanoma, where it promotes tumor invasiveness, epithelial-mesenchymal transition, and lymphatic metastasis via interactions with ERM proteins (ezrin/radixin/moesin). Clinically, PDPN correlates with poor prognosis in lung adenocarcinoma and Kaposi sarcoma. It also contributes to inflammatory diseases like rheumatoid arthritis by activating fibroblast-like synoviocytes. Current therapeutic strategies focus on monoclonal antibodies (e.g., NZ-1) and CAR-T cells targeting PDPN in clinical trials for brain tumors. Small-molecule inhibitors disrupting PDPN-CLEC-2 interactions are under preclinical evaluation for antimetastatic applications.

IHC image of CSB-RA017739MA1HU diluted at 1:300 and staining in paraffin-embedded human colorectal cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-Mouse IgG labeled by HRP and visualized using 0.05% DAB.

Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-Mouse IgG labeled by HRP and visualized using 0.05% DAB.
Overlay Peak curve showing 293 cells stained with CSB-RA017739MA1HU (red line) at 1:100. The cells were fixed in 4% formaldehyde (15min) and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated Goat Anti-Mouse IgG(H+L) at 1/200 dilution for 35 min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1µg/1*106cells) used under the same conditions. Acquisition of >10,026 events was performed.
