Lymphocyte activation antigen CD70 expressed by renal cell carcinoma is a potential therapeutic target for anti-CD70 antibody-drug conjugates.

Metastatic renal cell carcinoma (RCC) is an aggressive disease refractory to most existing therapeutic modalities. Identifying new markers for disease progression and drug targets for RCC will benefit this unmet medical need. We report a subset of clear cell and papillary cell RCC aberrantly expressing the lymphocyte activation marker CD70, a member of the tumor necrosis factor superfamily.

Suppression subtractive hybridization and expression profiling identifies a unique set of genes overexpressed in non-small-cell lung cancer.

Expression array data for >3000 individual clones from two suppression subtractive hybridization libraries revealed 147 genes overexpressed in non-small-cell lung cancer (NSCLC) cell lines. Of these 147 genes, 30 genes have previously unknown cancer association and 65 genes have been associated with cancers other than NSCLC. The identification of 52 genes previously associated with NSCLC by different methodologies supports the validity of the strategy used here.

Tumors associated with oncogenic osteomalacia express genes important in bone and mineral metabolism.

Oncogenic osteomalacia (OOM) is associated with primitive mesenchymal tumors that secrete phosphaturic factors resulting in low serum concentrations of phosphate and calcitriol, phosphaturia, and defective bone mineralization. To identify overexpressed genes in these tumors, we compared gene expression profiles of tumors resected from patients with OOM and histologically similar control tumors using serial analysis of gene expression (SAGE). Three hundred and sixty-four genes were expressed at least twofold greater in OOM tumors compared with control tumors.
