Identification of a novel putative non-coding RNA involved in proliferation arrest of a non-small cell lung carcinoma cell line treated with an original chemical substance, methyl-4-methoxy-3-(3-methyl-2-butanoyl) benzoate.

Non-small cell lung cancers remain particularly refractory to current treatments. Thus, characterisation of new molecular targets whose expression during chemotherapy could stop tumour growth, is required. In order to identify these new targets, we applied RT-PCR differential display (RT-PCR-DD) to a non-small cell lung cancer line (NSCLC-N6) treated by an original chemical substance, VT1, capable of arresting the proliferation of NSCLC-N6 cells in G1 phase.
