Autor: P. Mennonna, N. Di Lorenzo, Franco Ammannati, Gianluigi Taddei, Luisa Arganini, Annamaria Buccoliero, Pasquale Gallina

Publikováno v: Journal of Chemotherapy. 17:321-326

O6-Methylguanine-DNA-Methyltransferase (MGMT) is a DNA repair protein considered to be a chemosensitivity predictor. We evaluated the immunohistochemical MGMT expression in 28 consecutive oligodendroglial tumors (21 oligodendrogliomas, 5 mixed oligoa

Publikováno v: Applied Immunohistochemistry & Molecular Morphology. 9:35-41

Although melanin synthesis and the presence of melanosomes are exceptionally reported in nervous system tumors, there is no record of melanotic oligodendrogliomas in the literature. The purpose of the current study was to evaluate whether melanosomes

Publikováno v: The Journal of Pathology. 185:284-289

Studies on osteosarcoma cell lines point to the potential importance of transforming growth factor beta (TGF beta) as an autocrine factor which controls the growth of human osteosarcomas. To define further the role of TGF beta isoforms in these neopl

Merlin expression in secretory meningiomas: evidence of an NF2-independent pathogenesis? Immunohistochemical study

Autor: P. Mennonna, Gian Luigi Taddei, Antonio Taddei, Pasquale Gallina, Francesca Garbini, Franco Ammannati, Chiara Francesca Gheri, Anna Maria Buccoliero, Duccio Rossi Degl'Innocenti, Nicola Di Lorenzo, Francesca Castiglione, Luisa Arganini

Publikováno v: Applied immunohistochemistrymolecular morphology : AIMM. 15(3)

One of the most common chromosomal regions implicated in the meningiomas tumorigenesis is 22q12 where the neurofibromatosis 2 (NF2) gene resides. The NF2 tumor-suppressor gene encodes for the merlin/schwannomin protein, which is responsible for the i

Cyclooxygenase-2 (COX-2) overexpression in meningiomas: real time PCR and immunohistochemistry

Autor: Anna Maria Buccoliero, Franco Ammannati, Francesca Castiglione, Gian Luigi Taddei, Duccio Rossi Degl'Innocenti, Antonio Taddei, Luisa Arganini, P. Mennonna

Cyclooxygenase-2 (COX-2) is the inducible form of the enzyme involved in the first steps of the prostaglandins and thromboxane synthesis. COX-2 up-regulation is demonstrated in tumors where it can modulate tumoral progression, metastasis, multidrug r

Publikováno v: Calcified tissue international. 51(3)

A number of studies have demonstrated the pivotal role of collagen molecules in modulating cell growth and differentiation. In order to analyze the direct effects of collagen type I on the osteoblastic phenotype, we have devised an in vitro culture s
