Construction and Use of Lung Tumor Microarray for the Analysis of Gene Expression in Lung Cancer

Completed

Conditions studied: Lung Cancer

In brief

The proposed research intends to construct a set of tissue microarrays containing different types of normal and lung cancer tissues for the study of genes associated with lung cancer. Thus far we have generated a lung cancer tissue arrayusing paraffin embedded archival tissues from 300 lung turmors tissues and 100 adjacent normal tissues. Four- micrometer thickness sections have been cut from the tissue array and were used to survey gene expression status in arrayed tumors using immunohistochemistry methody. We are currently performing IHC studies ot 1) determine protein expression and its correlation with gene expression patterms ovserved using cDNA arrays. 2) Analyze protein expression in the chromosome remodeling pathyway in non-small cell lung cancer. And 3) determine the association of gene expression with lung tumor stage and clinical outcome. The current protocol is needed to complete the above studies and for the production of neuroendocrine tumors.
