In the last decade, much data has been generated concerning the molecular mechanisms of lymphangiogenesis and its significance in pathological conditions. This was mainly due to the discovery of lymphatic endothelial cell (LEC)-specific markers, such as vascular endothelial growth factor receptor-3 (VEGFR-3), LYVE-1, Prox-1 and podoplanin. Podoplanin,(More)
Oral cancer is an important cause of worldwide morbidity and mortality, with substantial economic, physiological, and psychosocial impacts due to its treatment modality and a great risk for recurrences and second primary oral squamous cell carcinomas (OSCC) development. Therefore, it is very important to understand the underlying cell biology of such(More)
AR (androgen receptor) and PSA (prostate-specific antigen) are involved in the pathogenesis of breast cancer, but their role is not clearly defined. The purpose of this study was to analyze by immunohistochemistry the AR and PSA (prostate-specific antigen) expression in 156 female breast carcinomas and to correlate the results with some histopathological(More)
The aims of our paper were to establish the main histopathological, histochemical and immunohistochemical aspects of tumoral stroma from salivary pleomorphic adenomas. For this purpose we investigated 103 cases by the classical histopathological technique with paraffin embedding and staining with Hematoxylin-Eosin (HE), Hematoxylin-Eosin-Safranin (HES),(More)
Renal carcinomas are a heterogeneous group of tumors, difficult to classify and identify precisely. Since their prognosis depends very much upon their type, precise diagnosis might mean the difference between therapeutic success and patient death. Cytokeratins are particularly useful for the identification of the epithelial nature of the tumors, because(More)
RATIONALE Rhinophototherapy has been shown to be effective in the treatment of allergic rhinitis. Considering that phototherapy with ultraviolet light (UV) induces DNA damage, it is of outstanding importance to evaluate the damage and repair process in human nasal mucosa. METHODS We have investigated eight patients undergoing intranasal phototherapy using(More)
Case–control studies have reported inconsistent results concerning the association between polymorphisms in the androgen and estrogen receptor (ER) genes and breast cancer. While several studies investigated the association between the androgen receptor (AR) gene, CAG repeat and breast cancer, for the CA and TA repeats in the ER genes there are considerably(More)
Angiogenesis is an essential process involved in the normal growth and differentiation. In its defective and excessive form, angiogenesis is a crucial event in the progression of many human diseases. Excessive angiogenesis was largely investigated in psoriasis, arthritis, diabetic retinopathy and malignant tumours. Soon after the discovery of angiogenic(More)
The particularities of lymphangiogenesis in different molecular types of breast cancer are virtually unknown and the contribution of microenvironment to this process has been ever less investigated. In the present study, we evaluated the relationships between lymphatic microvessel density (LMVD), mast cell density (MCD) and the different molecular subtypes(More)
Angiogenesis in normal and pathological conditions is a multi-step process governed by positive and negative endogenous regulators. Many growth factors are involved in different steps of angiogenesis, like vascular endothelial growth factors (VEGF), fibroblast growth factor (FGF)-2 or platelet-derived growth factors (PDGF). From these, VEGF and FGF-2 were(More)
