Non-small cell lung cancer (NSCLC), comprising 85% of lung cancer cases, has been
associated with resistance to chemo/radiotherapy. The hypoxic tumor
micro-environment, where insufficient vasculature results in poor drug penetrance
and sub-optimal chemotherapy in the tumor interiors contributes heavily to this
resistance. Additionally, epigenetic changes in tumorigenic cells also change
their response to different forms of therapy. In our study, we have investigated
the effectiveness of a combination of cisplatin with scriptaid [a pan-Histone
Deacetylase inhibitor (HDACi)] in a model that mimics the tumor microenvironment
of hypoxia and sub-lethal chemotherapy. Scriptaid synergistically increases the
efficacy of cisplatin in normoxia as well as hypoxia, accompanied with reduced
metastasis and enhanced DNA damage. Addition of scriptaid also overcomes the
cisplatin resistance exhibited in lung cancer cells with stabilized hypoxia
inducible factor 1 (HIF1)-? (mutant) and mutant p53. Molecular studies showed
that the combination treatment increased apoptotic cell death in both normoxia
and hypoxia with a dual role of p38MAPK. Together, our results suggest that the
combination of low dose cisplatin and scriptaid is cytotoxic to NSCLC lines, can
overcome hypoxia induced resistance and mutant p53- induced instability often
associated with this cancer, and has the potential to be an effective therapeutic
modality.
