Autor: Angelica A. Saetta, Nikolaos V. Michalopoulos, Gerassimos Voutsinas, Andreas C. Lazaris, Panayiotis S. Davaris

Publikováno v: European Journal of Surgical Oncology (EJSO). 29:38-43

Aims: DNA microsatellite instability is a well-known feature of hereditary non-polyposis colon cancer; however, its incidence in familial adenomatous polyposis, is unclear. We report the frequency of microsatellite instability and other genetic abnor

Crucial event in the metastasis of cancer cells is the secretion of matrix metalloproteinases (MMPs), which are responsible for the degradation of extracellular matrix (ECM). Among them, matrix metalloproteinase-2 (MMP-2) is a gelatinase, which degra

Publikováno v: Applied Immunohistochemistry & Molecular Morphology. 10:20-28

Breast cancer is a genetically complex disease and is frequently associated with nonrandom chromosomal alterations. The occurrence of aberrations involving chromosomes 1 and 17 in malignant tissues of breast cancer patients has not been studied syste

Markers of drug resistance in relapsing colon cancer

Autor: Panayiotis S. Davaris, Kavantzas N, Andreas C. Lazaris, N. Tsavaris, Haralambos Zorzos

Publikováno v: Journal of Cancer Research and Clinical Oncology. 128:114-118

Purpose: 5-Fluorouracil failure and drug resistance, which often occurs during chemotherapy, is still a great obstacle to the success of human colon cancer treatment. Thus, the comparative study of markers of drug resistance in cancer cells before an

Expression patterns of β-catenin in in situ and invasive breast cancer

Autor: Hariklia Gakiopoulou, Panayiotis S. Davaris, A. Keramopoulos, Anastasios J. Karayiannakis, Lydia Nakopoulou, Massimo Pignatelli

Publikováno v: European Journal of Surgical Oncology (EJSO). 27:31-36

Background β-Catenin plays a central role in the E-cadherin/catenin cell–cell adhesion complex and is possibly involved in cellular signalling pathways. In this study, we evaluated the expression patterns of this molecule in in situ and invasive b

Immunohistochemical Expression of Caspase-3 as an Adverse Indicator of the Clinical Outcome in Human Breast Cancer

Autor: Lydia Nakopoulou, Panayiotis S. Davaris, Effie Panayotopoulou, Andreas C. Lazaris, Paraskevi Alexandrou, Kalliopi Stefanaki

Publikováno v: Pathobiology. 69:266-273

Objective: Tumor growth is the net result of cell proliferation and cell loss by apoptosis. Caspase-3 (CPP32) has been considered as most directly correlated with apoptosis because of its location in the protease cascade pathway. The aim of this stud

Publikováno v: European Journal of Gastroenterology & Hepatology. 12:913-921

Classification of hepatic tumours and tumourlike conditions can sometimes be difficult to establish by light microscopy. Our aim was to determine the value of computerized interactive nuclear morphometry in the preoperative prediction of primary or m
