Excessive Alcohol Consumption Impairs Liver Regeneration and Promotes Fatty Liver Disease

A new study reveals that chronic alcohol use impairs liver regeneration by causing RNA missplicing due to ESRP2 deficiency, leading to cells being trapped in a non-functional state, which contributes to liver failure. The findings suggest potential treatment pathways targeting inflammation and RNA splicing to improve liver recovery.

Unveiling the Intricate Mechanisms of Intron Catalysis and Dynamics in Splicing

Scientists have gained new insights into the structural organization and catalytic mechanisms of group II introns, which are RNA molecules involved in splicing. Using cryo-electron microscopy, researchers visualized the intron ribonucleoprotein (RNP) complex at different stages of splicing. They discovered the intricate molecular interactions that position the branch helix and recognize the branchpoint nucleotide. The study also revealed the conformational dynamics of the intron RNP during the splicing process. These findings provide a better understanding of the fundamental reactions involved in RNA splicing and shed light on the evolution of splicing machines.
