27-hydroxycholesterol and DNA damage repair: implication in prostate cancer

Frontiers in Oncology, 2023
IntroductionWe previously reported that cholesterol homeostasis in prostate cancer (PC) is regulated by 27-hydroxycholesterol (27HC) and that CYP27A1, the enzyme that converts cholesterol to 27HC, is frequently lost in PCs. We observed that restoring the

Unveiling Hepatic Protein Alterations in Neonatal and Infant Biliary Atresia

Clinical Pharmacology &Therapeutics, Volume 119, Issue 6, Page 1584-1596, June 2026.
Pediatric populations differ from adults in drug elimination capacity. While current scaling methods account for enzyme and transporter maturation, they overlook comorbidities, such as biliary atresia (BA), a liver disease appearing within the first 2–8 weeks of life that can progress to cirrhosis.

Changes in the gut microbiome during fasting‐induced molting and its effects on gut–liver function

iMetaOmics, Volume 3, Issue 2, June 2026.
During fasting, harmful microbiota and metabolites rise, triggering intestinal injury and activation of the TGF‐β signaling pathway, which enhances intestinal stem cell proliferation. Concurrently, hepatic function declines, indicated by increased hepatic and serum bile acids and upregulation of the non‐classical bile acid synthesis pathway.

c.1263+1G>A Is a Latent Hotspot for CYP27A1 Mutations in Chinese Patients With Cerebrotendinous Xanthomatosis

Frontiers in Genetics, 2020
BackgroundCerebrotendinous xanthomatosis (CTX) is an autosomal recessive disorder of bile acid synthesis caused by mutations in the CYP27A1 gene. CTX is an underdiagnosed and potentially treatable disease, thus a detailed appreciation of the phenotypic ...

Metabolic Regulation of Immune Responses: Molecular Mechanisms, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 6, June 2026.
FBP1 loss drives immune evasion and therapy resistance by enhancing glycolysis, STAT3 activation, and PD‐L1 expression, leading to T cell exhaustion and NK cell inhibition. FBP1 restoration, via LNP‐mRNA or epigenetic modulation, reverses these immunosuppressive effects, reactivates cytotoxic T cells, promotes M1 macrophage polarization, and enhances ...

Nerve Ultrasound Detects Peripheral Nerve Enlargement in Cerebrotendinous Xanthomatosis

Muscle &Nerve, Volume 73, Issue 6, Page 1082-1088, June 2026.
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.

Bile acid metabolism and sleep: Mechanistic interplay and clinical implications of the gut–liver–brain axis

Sleep Research, Volume 3, Issue 2, Page 170-179, June 2026.
Abstract The bidirectional interplay between sleep and metabolic homeostasis is fundamental to physiological health. While the roles of glucose and lipid metabolism in sleep regulation have been extensively characterized, bile acids (BAs), which are traditionally viewed as digestive surfactants, are emerging as critical metabolic messengers with ...

Increased maternal and fetal cholesterol efflux capacity and placental CYP27A1 expression in preeclampsia[S]

Journal of Lipid Research, 2017
Preeclampsia is a pregnancy-specific condition that leads to increased cardiovascular risk in later life. A decrease in cholesterol efflux capacity is linked to CVD.

Novel splice-affecting variants in CYP27A1 gene in two Chilean patients with Cerebrotendinous Xanthomatosis

Genetics and Molecular Biology, 2015
Cerebrotendinous Xanthomatosis (CTX), a rare lipid storage disorder, is caused by recessive loss-of-function mutations of the 27-sterol hydroxylase (CYP27A1), producing an alteration of the synthesis of bile acids, with an accumulation of cholestanol ...

GLP‐1 agonists and the gut microbiome: A bidirectional relationship

British Journal of Clinical Pharmacology, Volume 92, Issue 5, Page 1309-1325, May 2026.
Abstract Glucagon‐like peptide‐1 (GLP‐1) receptor agonists have transformed the management of type 2 diabetes mellitus (T2DM) and obesity, yet their interactions with the gut microbiome remain an emerging frontier in pharmacological and metabolic research.
