Title | Abstract |
| Chemical suppression of an oncogenic splicing variant of AIMP2 induces tumour regression. | AIMP2 (aminoacyl-tRNA synthetase-interacting multifunctional protein 2) is a potent tumour suppressor that induces apoptosis in response to various oncogenic signals. AIMP2-DX2, an exon2-deleted splicing variant of AIMP2, is up-regulated in lung cancer and competitively suppresses the pro-apoptotic activity of AIMP2, resulting in tumorigenesis. In the present study we report that BC-DXI01, a synthetic compound, specifically reduces the cellular levels of AIMP2-DX2 through selective degradation of the AIMP2-DX2 mRNA transcript. We found that BC-DXI01-mediated cell death positively correlates with AIMP2-DX2 expression in the lung cancer cell lines tested. Administration of BC-DXI01 in a AIMP2-DX2-driven tumour xenograft mice model led to reduced tumour sizes and volumes of up to 60% in comparison with vehicle-treated mice group, consistent with decreases in AIMP2-DX2 transcript and protein levels. Taken together, our findings suggest that tumorigenic activity of AIMP2-DX2 can be controlled by the small chemical BC-DXI01, which can selectively suppress the AIMP2-DX2 mRNA transcript. |
