ARID5B‐mediated LINC01128 epigenetically activated pyroptosis and apoptosis by promoting the formation of the BTF3/STAT3 complex in β2GPI/anti‐β2GPI‐treated monocytes
Summary
Researchers identified how a protein called ARID5B activates a genetic pathway that triggers cell death through pyroptosis and apoptosis in monocytes associated with antiphospholipid syndrome. They found that ARID5B drives expression of a long non-coding RNA that promotes inflammatory cell death via a specific protein complex. The study suggests that targeting this pathway could offer a potential therapeutic approach for managing this autoimmune condition.
The H3K4me3 mark and chromatin accessibility at the ARID5B promoter are increased in vitro model mimicked APS. ARID5B-mediated LINC01128 induces pyroptosis and apoptosis via p-STAT3 by binding to BTF3. ARID5B is high- expressed in patients with primary APS and positively correlated with LINC01128 expression. OICR-9429 treatment mitigates pyroptosis and related inflammation in vivo and in vitro models mimicked APS.
