Objective: ING1 and ING4 are identified as candidate tumor suppressor genes acting in regulation of DNA damage responses and apoptosis through modulation of p53. Their defective function promotes tumor growth in melanoma and breast cancer. Our aim was to determine the overexpression of relevant p33ING1b and p29ING4 isoforms in patients with Renal Cell Cancer (RCC).
Methods: Peripheral Blood Mononuclear Cells (PBMCs) from tumor patients (Robson stage I-IV) were stimulated with overlapping peptides of p33ING1b/p29ING4 and results were compared with expression profiles in primary tumors.
Results: Early-stage and late-stage tumors demonstrated upregulated ING-isoform gene and protein expression. Early cancers were characterized by increased CD8 and IFN-γ protein and gene expression. Significant p33ING1b and p29ING4 tum.. View More»
