Background:The prognosis of squamous cell carcinoma of the oral tongue is poor and it would be beneficial to find prognostic markers to better adjust treatment. Bmi-1 controls cell cycle and self-renewal of tissue stem cells, transcription factor c-myc affects cell proliferation and apoptosis, and Snail regulates epithelial–mesenchymal transition. The(More)
BACKGROUND Well-differentiated follicular thyroid carcinoma usually has a favourable prognosis and metastases are rare. Toll-like receptors (TLRs) that take part in adaptive and innate immunity have, in many tumours, both apoptotic and antiapoptotic effects, making their role in tumourigenesis controversial. Chronic inflammation is involved in many cancers.(More)
The temporomandibular joint (TMJ) disc lacks functional replacement after discectomy. We investigated tissue-engineered bilayer polylactide (PLA) discs and autologous adipose stem cells (ASCs) as a potential replacement for the TMJ disc. These ASC discs were pre-cultured either in control or in differentiation medium, including transforming growth factor(More)
BACKGROUND To improve the prognostic evaluation of colorectal cancer requires new molecular markers. Cancerous inhibitor of protein phosphatase 2A (CIP2A) serves as an oncoprotein by targeting PP 2A-mediated inhibition of c-Myc. A prognostic role for CIP2A has been demonstrated in gastric, lung and tongue cancers. RESULTS CIP2A was overexpressed in 661(More)
To enable cancer to invade and to metastasize, the surrounding stroma must be degraded. Matrix metalloproteinase-7 (MMP-7) is capable of degrading many extracellular matrix proteins and cellular adhesions, is overexpressed in many malignancies, and plays a role in tumour progression. The purpose of this study was to evaluate the association between MMP-7(More)
BACKGROUND Oral squamous cell carcinoma (OSCC) and cutaneous squamous cell carcinoma (CSCC) are epithelial neoplasms of which OSCC has worse survival and higher risk of metastasis than CSCC. The aim of this study was to explore the differences of immunoexpressions between syndecan-1 and -2 in OSCC and head and neck CSCC. METHODS A total of 35 patients(More)
Anaplastic thyroid carcinoma (ATC) is one of the most lethal malignancies; poorly differentiated thyroid carcinoma (PDTC) is a new diagnosis for rare aggressive thyroid tumours. Surgery is often considered the only chance for survival, but the benefit of surgery and subsequent multimodal therapy is unclear. We retrospectively analyzed the outcome of 44 ATC(More)
The prognostication of patient outcome is one of the greatest challenges in the management of early stage oral tongue squamous cell carcinoma (OTSCC). This study introduces a simple histopathological model for the prognostication of survival in patients with early OTSCC. A total of 311 cases (from Finland and Brazil) with clinically evaluated early stage(More)
Toll-like receptors (TLRs) are important in barrier homeostasis, but their role in airborne allergies is not fully understood. The aim was to evaluate baseline and allergen-induced expression of TLR proteins in nasal epithelium during allergic rhinitis. Nineteen otherwise healthy non-smoking volunteers both allergic to birch pollen and non-allergic controls(More)
BACKGROUND Podocalyxin-like 1 (PODXL) is a cell-adhesion glycoprotein associated with aggressive tumor phenotype and poor prognosis in several forms of cancer. The aim of this study was to investigate PODXL expression in gastric cancer by use of two different antibodies. METHODS By tumor-tissue microarrays and immunohistochemistry we evaluated PODXL(More)
