KRIT1 regulates the homeostasis of intracellular reactive oxygen species. [PDF]
KRIT1 is a gene responsible for Cerebral Cavernous Malformations (CCM), a major cerebrovascular disease characterized by abnormally enlarged and leaky capillaries that predispose to seizures, focal neurological deficits, and fatal intracerebral ...

Case Report: A novel heterozygous nonsense mutation in KRIT1 cause hereditary cerebral cavernous malformation [PDF]
Cerebral cavernous malformation (CCM) is a vascular malformation of the central nervous system and mainly characterized by enlarged capillary cavities without intervening brain parenchyma. Genetic studies have identified three disease-causing genes (CCM1/

Unexpected distribution of KRIT1 inside the nucleus: new insight in a complex molecular pathway
KRIT1 is an 84kDa protein that lacks any relevant catalytic domains, associated with the cerebral cavernous malformation disease. We have investigated by means of ultrastructural immunocytochemistry the nuclear distribution of KRIT1 in different cell ...

Familial Cerebral Cavernous Malformations: Pathophysiology, Genetics, Biomarkers, and Treatment Perspectives. [PDF]
Cerebral cavernous malformations (CCMs) are vascular lesions in the brain caused by inherited genetic mutations in the CCM1/2/3 genes that disrupt normal blood vessel function. This work demonstrates that these mutations lead to endothelial dysfunction, inflammation, and iron accumulation, which can be detected by magnetic resonance imaging (MRI) and ...

Structural Basis for Small G Protein Effector Interaction of Ras-related Protein 1 (Rap1) and Adaptor Protein Krev Interaction Trapped 1 (KRIT1) [PDF]
Cerebral cavernous malformations (CCMs) affect 0.1-0.5% of the population resulting in leaky vasculature and severe neurological defects. KRIT1 (Krev interaction trapped-1) mutations associate with ∼40% of familial CCMs. KRIT1 is an effector of Ras-related protein 1 (Rap1) GTPase.

Circumferential actomyosin bundles anchored by CCM1 drive endothelial cell contraction and vessel constriction [PDF]
Blood vessels undergo extensive remodelling to acquire appropriate diameters, yet how endothelial cells coordinate changes in their number and shape to achieve this remains unclear.

Cerebral Cavernous Malformation: From Genetics to Pharmacotherapy. [PDF]
CCM1, CCM2, CCM3, MAP3K3, and PIK3CA genes mediate CCM pathogenesis by regulating the RhoA–ROCK, MAP3K3–KLF2/4, and PIK3CA–AKT–mTOR pathways, affecting processes such as cell migration, intercellular junctions, cell proliferation, inflammation, autophagy, EndMT, angiogenesis, and oxidative stress.

Heg1 and Ccm1/2 proteins control endocardial mechanosensitivity during zebrafish valvulogenesis
Endothelial cells respond to different levels of fluid shear stress through adaptations of their mechanosensitivity. Currently, we lack a good understanding of how this contributes to sculpting of the cardiovascular system.

Targeted Therapies for Slow-Flow Vascular Malformations. [PDF]
ABSTRACT Advances in genetic sequencing technologies have enabled the identification of key activating somatic variants in cellular signalling pathways involved in the pathogenesis of vascular malformations. Given that these genetic variants are also implicated in the pathogenesis of several cancers, the repurposing of targeted therapies developed in ...
