Abstract:
OBJECTIVETo explore the mechanism of regulating B cell-activating factor (BAFF) signalling pathway by NF-κB activator 1 (Act1) in B cell lymphoma so as to provide a new thinking for treatment of B cell lymphoma.
METHODSThe human B cell lymphoma cell lines including Raji, Daudi and BALL-1 were cultured, when the cells were in logarithmic phase, the RNA was extracted, and the Act1 was amplified by RT-PCR; and pTT5-Act1 expression plasmid was constructed and was transfected into cells; the Act1 was silenced by using Act1 mRNA; the NF-κB signaling pathway protein was detected by Western blot.
RESULTSAfter silence or overexpression of Act1, the proliferation levels of Raji, Daudi and BALL-1 cells were up- or down-regulated, respectively. Overexpression and silence of Act1 could down-or up-regulate BAFF-R expression level, furthermore could inhibit or activate of NF-κB signalling pahway, respectively.
CONCLUSIONAmong 3 above-mentioned B cell lymphoma cell lines, Act1 plays negative regulating role, indicating that the Act1 may be a promising therapeutic target for treating B cell lymphoma.
