Abstract
Experimental oncology commonly uses cells as oncological models, providing a framework for the testing of drugs, and investigation of cytotoxicity, mutagenesis and carcinogenesis. Investigations into poly-ADP-ribose polymerase 1 (PARP1) inhibition have become ever more relevant due to its approval as a therapeutic option for tumors with BRCA1/2 DNA repair-associated mutation and the seemingly high PARP expression levels in some tumor subtypes. In this study, we aimed to determine PARP1 gene expression of different hematological cancer-derived cell lineages and compare them to that of normal cell lines. PARP1 gene expression in seven different neoplastic lineages, representing three different hematological disorders (chronic myeloid leukemia, Burkitt lymphoma and acute lymphoblastic leukemia), was quantified by quantitative real-time polymerase chain reaction. All hematological malignant lineages in this study overexpressed PARP1 when compared to the normal cell line MRC-5, with Burkitt's lymphoma cells having the highest expression values (fold change: 93). Overexpression of PARP1 in hematological malignant lineages is a finding of crucial importance to future studies exploring possible cellular oncogenic pathways and supports investigations into the effectiveness of PARP1 inhibitors against hematological disorders.
