PURPOSE: Epithelial-mesenchymal transition (EMT), TP53, and Podoplanin have been implicated in the tumorigenesis and metastasis of human cancers. Nevertheless, the clinical significance of these markers in cancer patients is still not clear. In this study, we sought to determine the prognostic values of Vimentin, TP53, and Podoplanin in patients with cervical cancer. METHODS: Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot analysis were performed to determine the messenger RNA and protein expression levels of Vimentin, TP53, and Podoplanin, respectively, in cervical squamous cell carcinoma and adjacent normal cervical tissues...

The mechanisms underpinning the failure of inflammation to resolve in diseased musculoskeletal soft tissues are unknown. Herein, we studied bioactive lipid mediator (LM) profiles of tendon-derived stromal cells isolated from healthy donors and patients with chronic tendinopathy. Interleukin(IL)-1β treatment markedly induced prostaglandin biosynthesis in diseased compared to healthy tendon cells, and up regulated the formation of several pro-resolving mediators including 15-epi-LXA4 and MaR1. Incubation of IL-1β stimulated healthy tendon cells with 15-epi-LXA4 or MaR1 down-regulated PGE2 and PGD2 production...

The gut-associated lymphoid tissues (GALTs), including Peyer's patches (PPs), cryptopatches (CPs) and isolated lymphoid follicles (ILFs), establish a host-microbe symbiosis by the promotion of immune reactions against gut microbes. Microfold cell inducer (MCi) cells in GALTs are the recently identified mesenchymal cells that express the cytokine RANKL and initiate bacteria-specific immunoglobulin A (IgA) production via induction of microfold (M) cell differentiation. In the previous study, the Twist2-Cre driver was utilized for gene deletion in mesenchymal cells including MCi cells...

AIMS: Podoplanin expression in cancer-associated fibroblasts (CAFs) has been proposed as an unfavourable indicator in squamous cell carcinoma of the lung, but little is known about its clinical significance in early-stage lung adenocarcinoma. We evaluated the prognostic impact of podoplanin expression in patients with pathological stage (p-stage) IA lung adenocarcinoma as categorized by the 8(th) edition of the tumour-node-metastasis classification for lung cancer. METHODS AND RESULTS: Immunohistochemical analyses using anti-podoplanin antibody were performed on resected specimens from 158 patients with p-stage IA lung adenocarcinoma...

Recent data indicate that there are different subpopulations of Th17 cells that can express a regulatory as opposed to an inflammatory gene signature. The transmembrane glycoprotein PDPN is critical in the development of multiple organs including the lymphatic system and has been described on T cells in mouse models of autoimmune Th17 inflammation. Here, we demonstrate that unlike in mice, PDPN+ T cells induced under classic Th17-polarizing conditions express transcription factors associated with Th17 cells but do not produce IL-17...

Transplantation of engineered tissues with microvascular structure is advancing towards therapeutic application to improve the flow of blood and/or lymphatic fluids. In lymphatic disorders, transplantation of tissue-engineered lymphatic grafts can be an ideal treatment for draining excessive lymphatic fluid. In this study, we examined the transplantation of three-dimensional artificial human lymphatic network tissue (AHLT) fabricated by the cell accumulation technique into the subcutaneous tissue and fascia of mice...

BACKGROUND: Podoplanin (PDPN), a mucin-type transmembrane glycoprotein, is expressed in a variety of human cancer types, and contributes to tumor progression. Our goal was to evaluate PDPN expression in hepatocellular carcinoma (HCC) using both immunohistochemistry (IHC) and RNAscope in situ hybridization. MATERIALS AND METHODS: Twenty patients with HCC who underwent partial hepatectomy with curative intent were retrospectively analyzed. RESULTS: IHC gave positive results in 11 cases, while RNAscope assay for PDPN detected amplification in 16 cases...

OBJECTIVE: The underlying problem in lymphatic filariasis is irreversible swelling of the limbs (lymphedema), which is a unique feature of lymphatic insufficiency. It is still unclear whether the natural ability of lymphatics to form functional lymphatic vasculature is achieved or attenuated in the lymphedemal pathology. Clinical studies have clearly shown that circulating lymphatic progenitors (CLPs), a subset of bone-marrow derived mononuclear cells (PBMCs), contribute to post-natal lymph vasculogenesis...

The in vivo visualisation of the human lymphatic system is limited by the mode of delivery of tracing agents, depth of field and size of the area examined, and specificity of the cell markers used to distinguish lymphatic endothelium from the blood vessels and the surrounding tissues. These limitations are particularly problematic when imaging human lymphatic abnormalities. Firstly, limited understanding of the lymphatic disease aetiology exists with respect to genetic causes and phenotypic presentations. Secondly, the ability of a tracer to reach the entire lymphatic network within the diseased tissue is suboptimal...

Podoplanin, lymphatic vessel endothelial hyaluronic acid receptor-1, prospero-related homeobox-1 and vascular endothelial growth factor receptor 3 have been demonstrated to have crucial roles in the development of the lymphatic system and lymphangiogenesis process by combining with their corresponding receptors. Thus, the four markers have been widely used in labelling lymphatic vessels for the detection of lymphangiogenesis and lymphatic vessel invasion. Numerous authors have aimed to identify the roles of these four markers in the lymphatic system and the mechanisms have been partly clarified at the molecular level...

There is no therapeutic intervention proven to prevent the acute respiratory syndrome (ARDS). Novel mechanistic insights into the pathophysiology of ARDS are therefore required. Platelets are implicated in regulating many of the pathogenic processes which occur during ARDS, however the mechanisms remain elusive. The platelet receptor C-type lectin-like 2 (CLEC-2) has been shown to regulate vascular integrity at sites of acute inflammation. Therefore, the purpose of this study was to establish the role of CLEC-2 and its ligand podoplanin in a mouse model of ARDS...

C-type lectin-like receptor 2 (CLEC 2) is a platelet receptor that is critical during development in blood-lymph separation and implicated in thrombus stability in thrombosis and hemostasis. It is the only known platelet activatory receptor that participates in both these aspects of platelet function and is the only one to signal through a hemi-immunoreceptor tyrosine-based activation motif (hemITAM). Current investigations into the function of CLEC 2 in vivo have focused on knock-out studies in which both the receptor and its signaling are deleted, making it impossible to explore the possible signaling independent functions of the receptor which are indicated by its only known physiological ligand, podoplanin, being an integral membrane protein...

BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is an aggressive malignancy, with a high incidence and poor prognosis. In the past several decades, hundreds of proteins have been reported to be associated with the prognosis of ESCC, but none has been widely accepted to guide clinical care. This study aimed to identify proteins with great potential for predicting prognosis of ESCC. METHODS: We conducted a systematic review on immunohistochemical (IHC) prognostic markers of ESCC according to the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines...

Cancer patients have an increased risk of venous thromboembolism (VTE). In this review, we will summarize common and cancer type-specific pathways of VTE in cancer patients. Increased levels of leukocytes, platelets and tissue factor-positive (TF+) microvesicles are all potential factors that alone or in combination increase cancer-associated thrombosis. Lung and colorectal cancer patients often exhibit leukocytosis. Neutrophils could increase VTE in cancer patients by releasing neutrophil extracellular traps whereas monocytes may express TF...

OBJECTIVE: Squamous cell carcinomas (SCC) are the most common malignancies in the oral mucosa; these carcinomas have been preceded by potentially malignant oral disorders (PMODs), mostly oral leukoplakia (OL). No specific biomarker has been widely accepted for predicting the risk of malignant transformation of PMODs. The aim of this study was to develop an accurate prediction model for the malignant transformation of OL using clinical variables and candidate biomarkers. MATERIALS AND METHODS: To achieve this goal, 10 candidate biomarkers that had previously been reported as useful molecules were investigated: P53, Ki-67, P16, β-catenin, c-jun, c-met, insulin like growth factor II mRNA-binding protein (IMP-3), cyclooxygenase (COX-2), podoplanin (PDPN) and carbonic anhydrase 9 (CA9)...

BACKGROUND: Every actinic keratosis (AK) starts with atypia at the basal layers of the epidermis (AK I). Progression into invasive squamous cell carcinoma (iSCC) may occur following two main pathways, classical and differentiated. In the former, iSCC only occurs after involvement of the upper epidermal layers by atypical cells (AK III), while in the latter iSCC develops directly from AK I. In the anogenital mucosa, these two pathways are associated with differential expression of p53 and p16...

INTRODUCTION: Previous studies have shown increased expression of stromal markers in synovial tissue (ST) of patients with established rheumatoid arthritis (RA). Here, ST expression of stromal markers in early arthritis in relationship to diagnosis and prognostic outcome was studied. METHODS: ST from 56 patients included in two different early arthritis cohorts and 7 non-inflammatory controls was analysed using immunofluorescence to detect stromal markers CD55, CD248, fibroblast activation protein (FAP) and podoplanin...

Although it has been well-demonstrated that bone marrow mesenchymal stromal cells (MSCs) from CML patients do not belong to the Ph1-positive clone, there is growing evidence that they could play a role in the leukemogenesis process or the protection of leukemic stem cells from the effects of tyrosine kinase inhibitors (TKIs). The aim of the present study was to identify genes differentially expressed in MSCs isolated from CML patients at diagnosis (CML-MSCs) as compared to MSCs from healthy controls. Using a custom gene-profiling assay, we identified six genes over-expressed in CML-MSCs (BMP1, FOXO3, MET, MITF, NANOG, PDPN), with the two highest levels being documented for PDPN (PODOPLANIN) and NANOG...

Podoplanin (PDPN) is expressed in several normal tissues, such as lymphatic endothelial cells, podocytes of renal glomerulus, and type I alveolar cells of lung. PDPN activates platelet aggregation by binding to C-type lectin-like receptor-2 (CLEC-2) on platelet. Although monoclonal antibodies (mAbs) against human PDPN, mouse PDPN, rat PDPN, rabbit PDPN, dog PDPN, and bovine PDPN have been established, anticat PDPN (cPDPN) mAbs have not been developed. In this study, we immunized mice with Chinese hamster ovary (CHO)-K1 cell lines expressing cPDPN, and developed anti-cPDPN mAbs...
