This article discusses the findings of a study on moyamoya disease (MMD), a condition characterized by the occlusion of the intracranial internal carotid artery and the formation of collateral vessels. The study focuses on the differential protein metabolism among different subtypes of MMD and the role of WNT4 (wingless‐type MMTV integration site family member 4) in causing cellular impairments by reducing microtubule stability. The researchers used proteomic profiling and in vitro experiments to identify the differences in protein metabolism and explore the potential mechanisms of haemorrhagic MMD. The study suggests that overexpression of WNT4 may lead to decreased stability of cellular microtubules, which could contribute to the rupture and hemorrhage of moyamoya vessels. These findings provide new insights into the biomarkers and mechanisms of haemorrhagic MMD. [Extracted from the article]

This article discusses a study on moyamoya disease (MMD), a rare cerebrovascular condition characterized by narrowing of the intracranial internal carotid arteries. The study aims to identify specific metabolomic changes and biomarkers that can distinguish between different subtypes of MMD for clinical diagnosis. The researchers used metabolomics analysis to identify differential metabolite features in patients with MMD compared to healthy controls. They found that LPC 16:1-2, a type of lipid, was significantly lower in patients with ischaemic MMD and could potentially serve as a biomarker for this subtype. Additionally, the study explored the effects of LPC supplementation on cell viability and angiogenesis in MMD. The findings suggest that LPC supplementation may have therapeutic potential for managing MMD. [Extracted from the article]
