Targeting Chromatin-Mediated Transcriptional Control of Gene Expression in Non-Small Cell Lung Cancer Therapy: Preclinical Rationale and Clinical Results
Abstract
Targeting chromatin-mediated transcriptional control of gene expression is nowadays considered a promising new strategy, transcending conventional anticancer therapy. As a result, molecules acting as DNA demethylating agents or histone deacetylase inhibitors (HDACi) have entered the clinical arena in the last decade. Given the evidence suggesting that epigenetic regulation is significantly involved in lung cancer development and progression, the potential of epigenetically active compounds to modulate gene expression and reprogram cancer cells to a less aggressive phenotype is, at present, a promising strategy. Accordingly, a large number of compounds that interact with the epigenetic machinery of gene expression regulation are now being developed and tested as potential antitumor agents, either alone or in combination with standard therapy. The preclinical rationale and clinical data concerning the pharmacological modulation of chromatin organization in non-small cell lung cancer (NSCLC) is described in this review. Although preclinical data suggest that a pharmacological treatment targeting the epigenetic machinery has relevant activity over the neoplastic phenotype of NSCLC cells, clinical results are disappointing, leading ...Continue Reading
