The placental-derived growth factor (PIGF) is a dimeric glycoprotein showing a high degree of sequence similarity to the vascular endothelial growth factor. Alternative splicing of the PIGF primary transcript gives rise to two forms, named PIGF-1 and PIGF-2, which differ only in the insertion of a highly basic 21-amino acid stretch at the carboxyl end. The(More)
Placenta growth factor (PlGF) and vascular endothelial growth factor (VEGF) represent two closely related angiogenic growth factors active as homodimers or heterodimers. Since goiters of the thyroid gland are extremely hypervascular, we investigated the expression of PlGF, VEGF and their receptors, Flt-1 and Flk-1/KDR, in a small panel of human goiters from(More)
The heat shock proteins (Hsps) have an important role in the cytoprotection and repair of cells and tissues. One potential mechanism of protection is the ability of Hsp to inhibit genetic expression of proinflammatory cytokines, the transcription of which is dependent on nuclear factor-kappa B (NF-kappaB) activation. In this study, we evaluated the ability(More)
Epithelia in the human airways, from the nasal aperture to the alveoli, are covered in a protective film of fluid containing a number of antimicrobial proteins. Defensins are single-chain, strongly cationic peptides and are one of the most extensively studied classes of antimicrobial peptides. Moxifloxacin (MXF) is a fluoroquinolone that acts against both(More)
Neoangiogenesis is a prerequisite for tumor growth and metastasis. In germ cell cancer patients with the disease limited to the testicle (stage A), tumor-associated neovascularization is predictive of metastatic disease (stage B). To investigate the molecular mechanisms underlying neovascularization in human germ cell tumors (GCTs), we analysed the(More)
The teratocarcinoma-derived growth factor-1 (TDGF-1) gene codes for a 188-aminoacid glycoprotein that shares structural homology with the epidermal growth factor (EGF) family of growth factors. TDGF-1 is highly expressed in the undifferentiated embryonal carcinoma stem cell line NTERA2 clone D1 (NT2/D1) and its expression is downregulated in response to(More)
The lipophilic yeast Malassezia furfur is a member of the cutaneous microbiota, also associated with several chronic diseases such as pityriasis versicolor, folliculitis, seborrhoeic dermatitis, and some forms of atopic dermatitis, psoriasis and confluent and reticulate papillomatosis. In this study we determined the immunomodulatory and invasive capacity(More)
Some species of Candida are opportunistic pathogens that can cause disease in a host immunocompromised by underlying local or systemic pathological processes. C. albicans is the species most often associated with oral lesions, but other species of Candida, including C. glabrata, C. tropicalis and C. parapsilosis, have also been isolated in the saliva of(More)
BACKGROUND Captopril is an angiotensin-converting enzyme inhibitor with sulphydryl groups in its chemical structure. It is commonly used as an antihypertensive drug. The occurrence of pemphigus vulgaris has repeatedly been reported in patients receiving captopril. The capacity of captopril and pemphigus serum to induce acantholysis, in vivo or in vitro, has(More)
OBJECTIVES 3-O-methylfunicone (OMF), a secondary metabolite produced by Penicillium pinophilum, affects cell proliferation and motility in a variety of human solid tumours. The aim of this study was to demonstrate whether OMF has the ability to arrest cell division and motility, in a human mesothelioma cell line. Malignant mesothelioma is an aggressive(More)
