Delayed diagnosis of 3β‐HSD7 deficiency in adolescence: Two case reports and review of the literature

open access: yesJPGN Reports, EarlyView.
ABSTRACT Congenital bile acid synthesis defects (BASD), the most common of which is 3β‐hydroxy‐Δ5‐C27‐steroid dehydrogenase oxidoreductase (3β‐HSD7) deficiency, are a rare cause of fat‐soluble vitamin malabsorption. We describe a 14‐year‐old girl who presented at 14 months with a left distal femur fracture and failure to thrive.

Proteomics of Nitrotyrosine: Integrating Mass Spectrometry and Immunodetection in Redox‐Driven Pathology

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Nitrooxidative stress, driven by excess reactive nitrogen species like peroxynitrite, contributes to the pathogenesis of many chronic diseases. Among its molecular footprints, 3‐nitrotyrosine (3NT) has emerged as a biologically relevant marker of protein nitration.

Nerve Ultrasound Detects Peripheral Nerve Enlargement in Cerebrotendinous Xanthomatosis

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder caused by variants in the CYP27A1 gene, resulting in cholestanol accumulation in various tissues, including peripheral nerves. Polyneuropathy is common but often under‐recognized in CTX.

Cholesterol 25-hydroxylase production by dendritic cells and macrophages is regulated by type I interferons [PDF]

open access: yesJournal of Leukocyte Biology, 2010
Abstract TLR-mediated induction of cholesterol 25-hydoxylase transcription in dendritic cells and macrophages is dependent on IFN-α/IFN-β and signaling through INF-αR and STAT1. The oxysterol-producing enzyme CH25H plays an important role in regulating lipid metabolism, gene expression, and immune activation.

Unilateral mastication‐induced memory deficits linked to disrupted hippocampal cholesterol metabolism in rats

open access: yesVIEW, EarlyView.
Unilateral mastication, a common oral habit, induces cognitive decline in rats by disrupting hippocampal cholesterol metabolism. It triggers astrocyte hyperplasia, enhances cholesterol synthesis, impairs transport/degradation, and reduces 24‐hydroxycholesterol (24‐OHC), ultimately damaging synaptic function.
