Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

open access: yesBrain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Malignant craniopharyngiomas: Institutional experience and literature review

open access: yesBrain Pathology, EarlyView.
We report the second case of malignant craniopharyngioma with BAP1 and TP53 mutations. A literature review identified 44 cases of malignant craniopharyngiomas with a median overall survival of 6 months. Eighteen (41%) occurred in patients without any history of radiation, suggesting that mechanisms other than radiation have contributed to their ...

Optic nerve sheath meningioma exhibits neural niche‐associated transcriptomic features and rare copy number variation‐linked evolution

open access: yesBrain Pathology, EarlyView.
Optic nerve sheath meningiomas are typically NF2‐intact with few copy number alterations and are generally clinically indolent. Rare aggressive recurrences are associated with progressive accumulation of copy number variations, including CDKN2A/B homozygous deletion, 1q gain, and 14q loss.

Hypoxia Exacerbates Periapical Periodontitis‐Associated Pathological Bone Loss via the Hypoxia‐Inducible Factor‐2α‐Calmodulin‐Dependent Protein Kinase IV Axis

open access: yesCell Proliferation, EarlyView.
Hypoxia exposure activates HIF‐2α, which binds to the Camk4 promoter to enhance RANKL‐mediated osteoclast differentiation, leading to aggravated alveolar bone resorption in periapical periodontitis. ABSTRACT Periapical periodontitis is one of the most common inflammatory bone destructive diseases. Epidemiological evidence suggests that hypoxia exposure,

Lactate Accelerates Early Angiogenesis and Bone Regeneration Through Macrophage M1 Polarisation

open access: yesCell Proliferation, EarlyView.
During the early stage of bone defect healing, lactate accumulates and contributes to increasing NOD1 expression by stabilising HIF1α that in turn triggers a calcium influx, which ultimately polarises macrophages towards the M1 phenotype and accelerates vascularisation of endothelial cells.
