Researchers found that a synthetic gene-regulating compound called SynGR1 can recruit BRD4 to bypass gene-silencing structures without disrupting them and reactivate silenced genes. The findings point to new strategies for diseases like Friedrich’s ataxia and Huntington’s disease. 🧪 bit.ly/4hgkfb6

St. Jude researchers discovered that the tumor suppressor SPOP switches between an inactive "double-donut" structure and active filaments. The findings reveal how certain cancer mutations alter SPOP activity and may inform new therapeutic strategies. bit.ly/3R5c7zx
