Succinylation: A novel regulatory axis in cholelithiasis-insights from lysine acetyltransferase 2A/adenosine monophosphate-activated protein kinase signaling

Cholelithiasis represents a common clinical condition within the digestive tract and continues to pose a substantial global health challenge, largely due to its high rate of recurrence and a scarcity of effective non-surgical interventions. Although protein succinylation has been widely characterized as a post-translational modification, its implications in cholelithiasis pathogenesis had remained poorly defined. A groundbreaking study by Wang <i>et al</i> demonstrates that lysine acetyltransferase 2A-mediated succinylation of adenosine monophosphate-activated protein kinase suppresses cholelithiasis. This work not only provides novel mechanistic insights into cholelithiasis but also establishes succinylation as a promising therapeutic target, thereby addressing a critical knowledge gap in the field.
