RNA Sensor Platform for Targeting Cancer Fusion Genes and Transcripts
Many cancers have recurrent chromosomal translocations leading to the fusion of two genes. Often, said cancers are aggressive, have a poor prognosis with metastasis or recurrence, and do not have effective and targeted treatment. The challenge of many fusion-positive cancers is the lack of established targets downstream of the gene fusion despite years...
