摘要：
In one embodiment, a B cell specific aptamer-siRNA chimera is provided. The B cell specific aptamer-siRNA chimera may include an RNA aptamer that binds BAFF-R and an siRNA molecule conjugated to the RNA aptamer via a nucleotide linker. In another embodiment, a B cell specific RNA aptamer is provided. The RNA aptamer may be a molecule that binds to BAFF-R that has the sequence SEQ ID NO:37, SEQ ID NO:38 or SEQ ID NO:39. In some embodiments, the RNA aptamer is conjugated, via a nucleotide linker, to an siRNA molecule that suppresses expression of one or more target oncogenes in one or more B cells. In one aspect, the one or more target oncogenes are selected from Bcl6, Bcl2, STAT3, Cyclin D1, Cyclin E2 and c-myc. In another embodiment, methods for treating a B cell malignancy in a cancer patient are provided. Such methods may include administering a therapeutically effective amount of a therapeutic composition, the therapeutic composition comprising a B cell specific RNA aptamer that binds BAFF-R.
