Thrombomodulin (TM, also known as CD141), which functions as an anticoagulant, is widely expressed on cell surface of a variety of cell types, including human blood cells as well as certain immune cells. To determine whether TM could be a potential marker for OSCC diagnosis as well as a molecular target for OSCC therapy, we examined the expression of TM in an oral cancer tissue microarray with 153 oral cancer tissues. Further, we also analyzed the expression of TM on DCs of 36 OSCC patients and 36 healthy donors...

The prognosis of recurrent/metastatic (R/M) squamous cell carcinoma of the head and neck (HNSCC) after failure of first line chemotherapy is dismal. Until the publication of the results of CheckMate 141, not a single agent provided any survival benefit as a second line treatment for R/M HNSCC. Areas covered: A comprehensive review of the literature was conducted on the role of nivolumab in HNSCC. Expert commentary: Nivolumab is approved by the Food and Drug Administration for the treatment of patients based on the results of CheckMate 141 showing an overall survival benefit as compared to standard care (single agent docetaxel, methotrexate, or cetuximab)...

INTRODUCTION : Esophagitis dissecans superficialis (EDS) is a rare desquamative disorder of the eso-phagus, characterized by sloughing of the superficial mucosa. It is a benign entity of uncertain etiology. Most cases of EDS are idiopathic but can be caused by medications, hot beverages, chemical irritants, celiac disease and many skin conditions. AIM: Knowing that few case series have described this entity, we decided to review all the cases diagnosed in our center to characterize them...

PURPOSE: Head and neck squamous cell carcinoma (HNSCC) is one of the most common human cancer types with a very poor prognosis despite improvements in therapeutic modalities. The major known risk factors are tobacco use and alcohol consumption or infection with high-risk human papilloma viruses (HPV), especially in oropharyngeal tumors. The current management based on the assessment of a variety of clinical and pathological parameters does not sufficiently predict outcome. METHODS: Chromosomal alterations detected in HNSCCs were characterized by metaphase comparative genomic hybridization (CGH) and correlated with clinical parameters as well as survival time...

Recently the Aurora-Kinases (Aurk) moved into the focus as novel disease related biomarkers and therapeutic targets. Elevated Aurora-Kinase expression has been found in a number of malignancies, amongst them HNSCC. For esophageal cancer, the AurkA Phe31-Ile polymorphism has previously been associated with tumor progression. Here we evaluated the treatment efficiency of HNSCC cell radiation as a function of Aurora-Kinases in HNSCC cell lines. Moreover, we investigated a potential sensitization to radiation by a cell treatment with the inhibitors Alisertib, Barasertib, Docetaxel and VX-680...

Snail is a key regulator of epithelial-mesenchymal transition (EMT) and plays an important role in tumor progression and metastasis. Snail is rapidly degraded in the cells and its protein level is critically controlled. Although several E3 ligases regulating Snail degradation have been defined, the deubiquitinases (DUBs) responsible for Snail deubiquitination are less studied. We identified ovarian tumor domain-containing ubiquitin aldehyde binding protein 1 (OTUB1) as a DUB that stabilizes Snail through preventing its ubiquitination and proteasomal degradation...

Non-small cell lung cancer (NSCLC), including adenocarcinoma and squamous cell carcinoma, is the leading cause of death from lung malignancies and has a poor prognosis due to metastasis. Suppressor of cytokine signalling-2 (SOCS2), a feedback inhibitor of cytokine signalling, has been shown to be involved in growth control. Here, we show that SOCS2 were significantly downregulated in tumour foci in NSCLC patients. The expression levels of SOCS2 significantly correlated with clinical stage, lymph node metastasis, histological subtype and survival time...
