To investigate the level of SAa2,6Gal and a2,3Gal linked receptors on human bronchial epithelial cells, and relate this to the ability of both human and avian influenza viruses to infect bronchial epithelial cells

RNA interference (RNAi) provides an experimental tool for functional genomics analysis. We screened a genome-wide RNAi library to identify new genes involved in lung cancer cell proliferation. 72 % from the 257 genes identified were involved in general gene expression processes, 16 % were of unknown function or unrelated to proliferation, and 12% consisted of uncharacterized genes. These last sets of genes provide potential novel targets for lung cancer treatment.

This study investigated the role of the GRP78 in prostate cancer progression and the development of castration-resistant prostate cancer, where cancer cells continue to survive despite the stress of an androgen-starved environment.

Nodal involvement in bladder cancer is an independent indicator of prognosis. This study employed an iterative machine learning process called genetic programming on quantitative expression values of 70 genes to classify primary urothelial carcinoma samples into those associated with or without nodal metastasis. The generated rules showed a strong predilection for ICAM1, MAP2K6 and KDR resulting in gene expression motifs that cumulatively suggested a pattern ICAM1>MAP2K6>KDR for node positive ca

We used Ciphergen technology based on SELDI TOF-MS (Surface Enhanced Laser Desorption/Ionisation Time-of-Flight Mass Spectrometry) for analysis of protein expression profiles of 105 breast cancer tissue samples. The aim of this study was the identification of single proteins or protein patterns specific for different tumour subgroups, which should take advantage of the biomarker as an alternative to commonly used diagnostic and prognostic characteristics.

The purpose of our study was to evaluate soluble matrixmetalloproteinases (MMPs) and their inhibitor (TIMP1) associated to leg ulcer wound fluid in comparison with the tissue localized ones. We aimed to develop an easy-to-perform protocol for the quantification of soluble MMPs / TIMP and associate the obtained levels with the disease stage and prognostic.

Plasma proteins serve as good indicators of disease as there are representative proteins from several cellular processes and thus a potential source for biomarker discovery. The large dynamic range of plasma proteins makes the analysis very challenging, as a large number of low abundance proteins are masked by a few high abundance proteins.

We have compared two different solubilization buffers, we also evaluated protein precipitation with ethanol and optimized 2-DE conditions for human myeloma proteins.

Protein was extracted from 7-year old FFPE samples of B-cell lymphoma and mamma carcinoma, followed by ULS labeling. Samples were used for single or two color assays using a custom-made antibody array. We observed differential expression levels for several captured analytes. In B-cell lymphoma, expected high levels of IgM were detected, while high levels of CA19-9, a putative marker, were found for the breast cancer tissue.

Breast cancer has diverse metastatic behavior. Subpopulations of cells with enhanced metastatic abilities either to bone (1833) or to lung (4175) have been isolated by the group of J. Massague by in vivo selection of MDA-MB-231 cells. We performed the 2-DE analysis of the cell lines. We have found and identified 11 differentially expressed protein spots.
