摘要
Background:Cerebral cavernous malformations(CCMs),a major neurosurgical condition,characterized by abnormally dilated intracranial capillaries,result in increased susceptibility to stroke.KRIT1(CCM1),MGC4607(CCM2),and PDCD10(CCM3)have been identified as causes of CCMs in which at least one of them is disrupted in most familial cases.Our goal is to identify potential biomarkers and genetic modifiers of CCMs,using a global comparative omics approach across several in vitro studies and multiple in vivo animal models.We hypothesize that through analysis of the CSC utilizing various omics,we can identify potential biomarkers and genetic modifiers,by systemically evaluating effectors and binding partners of the CSC as well as second layer interactors.Methods:We utilize a comparative omics approach analyzing multiple CCMs deficient animal models across nine independent studies at the genomic,transcriptomic,and proteomic levels to dissect alterations in various signaling cascades.Results:Our analysis revealed a large set of genes that were validated across multiple independent studies,suggesting an important role for these identified genes in CCM pathogenesis.Conclusion:This is currently one of the largest comparative omics analysis of CCM deficiencies across multiple models,allowing us to investigate global alterations among multiple signaling cascades involved in both angiogenic and non-angiogenic events and to also identify potential biomarker candidates of CCMs,which can be used for new therapeutic strategies.
