Abstract
NEW FINDINGS What is the central question of this study? To reveal the role and biological mechanism of PDPN in the progression of gastric cancer. What is the main finding and its importance? This study focused on a prognostic predictor, PDPN, which acted as a promoter in the progression of gastric cancer through the activation of Ezrin expression and CAFs. This finding may expand a new route for the gene-targeted therapy in gastric cancer. ABSTRACT Gastric cancer (GC) is a frequent malignant disease and the main cause of cancer-related death in the world. Podoplanin (PDPN) has been proved to be involved in the progression of various cancers. However, the role and biological mechanism of PDPN in GC are still vague. In our study, we detected the expression of PDPN in GC tissues and cell lines using RT-qPCR, western blot and datasets. The overall survival of GC patients was analysed with a Kaplan-Meier plot. The effects of PDPN overexpression and silencing on GC cell progression were assessed by Cell Counting Kit-8, flow cytometry and a wound healing assay. Besides, the modulation of PDPN on ezrin activation was investigated. We further explored the role of PDPN in the crosstalk between GC cells and cancer associated fibroblasts (CAFs). Results showed that PDPN was upregulated in GC tissues and cell lines. High expression of PDPN was correlated with poor prognosis of GC patients. PDPN positively regulated the viability, migration and invasion, but inhibited apoptosis, of GC cells by mediating the activation of ezrin. Meanwhile, the change in PDPN in GC cells activated CAFs and promoted the production of cytokines secreted by CAFs, which induced the progression of GC cells. These findings may provide a novel target for GC therapy.

Abstract
Podoplanin (PDPN) is a cell-surface mucin-like glycoprotein that plays a critical role in tumor development and normal development of the lung, kidney, and lymphatic vascular systems. PDPN is overexpressed in several tumors and is involved in their malignancy. PDPN induces platelet aggregation through binding to platelet receptor C-type lectin-like receptor 2. Furthermore, PDPN modulates signal transductions that regulate cell proliferation, differentiation, migration, invasion, epithelial-to-mesenchymal transition, and stemness, all of which are crucial for the malignant progression of tumor. In the tumor microenvironment (TME), PDPN expression is upregulated in the tumor stroma, including cancer-associated fibroblasts (CAFs) and immune cells. CAFs play significant roles in the extracellular matrix remodeling and the development of immunosuppressive TME. Additionally, PDPN functions as a co-inhibitory molecule on T cells, indicating its involvement with immune evasion. In this review, we describe the mechanistic basis and diverse roles of PDPN in the malignant progression of tumors and discuss the possibility of the clinical application of PDPN-targeted cancer therapy, including cancer-specific monoclonal antibodies, and chimeric antigen receptor T technologies.

Abstract
Background: The prognostic significance of podoplanin (PDPN) in tumor cells for cancer
patients’ survival remains controversial. Therefore, we performed this
meta-analysis to clarify the relationship between the podoplanin-positive
tumor cells and cancer prognosis. Method: Eligible studies were identified by searching the Pubmed and EBSCO online
databases up to August 2019. Hazard ratios (HRs) with 95% confidence
intervals (CIs) were calculated to evaluate the correlation between
podoplanin expression and overall survival (OS) and/or disease-free survival
(DFS) and odds ratios (ORs) with 95% CIs severed as the summarized
statistics for clinicopathological characteristic. Results: A total of 2155 patients from 21 eligible studies were included. The results
revealed that high expression of podoplanin was associated with a poor
survival rate in cancer patients. Further subgroup analysis stratified by
tumor type showed that podoplanin-positive tumor cell infiltration had a
negative prognostic effect associated with survival in esophageal cancer and
oropharyngeal cancer. In addition, high expression of these cells was
significantly associated with N stage, T stage, TNM stage and vascular
invasion. Conclusion: Our study suggests the over-expression of podoplanin might be a significant
prognostic indicator for patients with esophageal and oropharyngeal
cancer.

Cancer Sci 2016; 107:1243-9. [PMID: 27389969 PMCID: PMC5021026 DOI: 10.1111/cas.13007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2016] [Revised: 06/30/2016] [Accepted: 07/05/2016] [Indexed: 12/19/2022] Open
Abstract
Podoplanin, a transmembrane sialomucin-like glycoprotein, was recently shown to be involved in tumor progression and metastasis, and its potential role in facilitating platelet-based tumor embolization and promigratory phenotype of cancer cells was also demonstrated. In this study, we assessed the clinical significance of tumoral podoplanin expression in 295 patients with clear cell renal cell carcinoma (ccRCC) through immunohistochemistry on tissue microarrays and analyzing the staining intensity. Univariate analysis suggested an adverse prognostic effect of high tumoral podoplanin expression on patients' overall survival (OS) and recurrence-free survival (RFS) (P < 0.001 for both). In the multivariate analysis, high tumoral podoplanin expression (using staining intensity as either a continuous or dichotomous variable) was still an independent adverse prognostic factor for patient survival (OS, P < 0.001, RFS, P < 0.001 for continuous; OS, P < 0.001, RFS, P = 0.002 for dichotomous). Moreover, stratified analysis identified a higher prognostic power in the intermediate/high risk patient groups. After utilizing those parameters in the validated multivariate analysis, two nomograms were constructed to predict ccRCC patients' OS and RFS (c-index 0.815 and 0.805, respectively), and performed better than existing integrated models (P < 0.001 for all comparisons). In conclusion, high tumoral podoplanin expression could independently predict an adverse clinical outcome for ccRCC patients, and it might be useful in future for clinical decision-making and therapeutic developments.
