Advances in role and mechanisms of Ras-related C3 botulinum toxin sub-strate 1 in pulmonary diseases
Ras-related C3 botulinum toxin substrate 1(RAC1)is a crucial member of the Ras GTPase super-family,exerting an overriding role in cell behaviors such as motility,proliferation and adhesion,and is involved in regu-lating vascular permeability and cellular barrier function.Recently,the significance of RAC1 in the etiology and progres-sion of various pulmonary disorders has garnered increasing attention,which sheds light on lung disease study.In this re-view,we introduce the characteristics of RAC1 systematically and recapitulate its effects and molecular mechanisms in the context of lung tumors,chronic obstructive pulmonary disease,lung injury and pulmonary arterial hypertension,hoping to provide new insights for future pulmonary disease treatment.
