Myelomonocytic cells (i.e., monocytes or macrophages) play a key role in tumor progression as revealed by numerous mice tumor model studies. However, their contribution in human tumor progression is not well-studied. Using Renal Cell Carcinoma (RCC) as a model for human cancer, we performed a transcriptomal profiling of blood monocytes from RCC patients to investigate the contribution of these cells in cancer progression.

Blood monocytes from RCC patients (with early or metastatic disease) or healthy donors (controls) were isolated, and then differential gene expression was detected with Limma.
