Protein Expression in Tumor Tissue Samples From Patients With Cancer of the Oropharynx

2014-08-27 03:22:15 | BioPortfolio

Summary

RATIONALE: Studying the proteins expressed in samples of tumor tissue from patients with cancer may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors plan better treatment for patients with cancer of the oropharynx.

PURPOSE: This laboratory study is looking at protein expression in tumor tissue samples from patients with cancer of the oropharynx.

Description

OBJECTIVES:

- To investigate if some of the differences in gene expression are also reflected at the protein level.

- To determine whether differences in gene expression that are also reflected at the protein level can be used to develop markers for early detection and disease surveillance.

- To identify targets for therapy.

OUTLINE: Archived tumor tissue samples are analyzed for expression of standard immunohistological markers (e.g., p16, p53, and Ki-67) as well as expression of genes identified in a previous gene expression study. Protein expression data are tested for clinical and demographic correlates and compared with gene expression data.

A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

Hybridization of a nucleic acid sample to a very large set of oligonucleotide probes, which are attached to a solid support, to determine sequence or to detect variations in a gene sequence or expression or for gene mapping.

Meta-analysis of randomized trials in which estimates of comparative treatment effects are visualized and interpreted from a network of interventions that may or may not have been evaluated directly against each other. Common considerations in network meta-analysis include conceptual and statistical heterogeneity and incoherence.
