Targeting cytochrome P450 46A1 and brain cholesterol 24-hydroxylation to treat neurodegenerative diseases

Exploration of Neuroprotective Therapy, 2021
The brain cholesterol content is determined by the balance between the pathways of in situ biosynthesis and cholesterol elimination via 24-hydroxylation catalyzed by cytochrome P450 46A1 (CYP46A1). Both pathways are tightly coupled and determine the rate

Liver X Receptor α (LXRα) Regulates 5β‐Reductase (AKR1D1) Expression in Avian Embryos: Implications for Yolk Steroid Metabolism

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Steroid‐mediated maternal effects are well‐studied as a source of phenotypic variation. In bird eggs, the yolk contains various steroids that can influence embryonic development. However, one complicating factor in understanding how yolk steroids affect development is that the embryo metabolizes yolk steroids to regulate exposure.

A Japanese prospective multicenter study of urinary oxysterols in biliary atresia

Scientific Reports, 2021
Diagnosis of biliary atresia (BA) can involve uncertainties. In the present prospective multicenter study, we considered whether urinary oxysterols represent a useful marker for diagnosis of BA in Japanese children.

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

Pest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

Novel approaches for drug development against chronic primary pain: A systematic review

British Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

Ca2+ channel blockers verapamil and nifedipine inhibit apoptosis induced by 25-hydroxycholesterol in human aortic smooth muscle cells

Journal of Lipid Research, 1997
We have characterized the death of human aortic smooth muscle cells induced by 25-hydroxycholesterol, an oxidation product of cholesterol. Chromatin condensation characteristic of apoptosis was observed by enzymatic (TUNEL) staining of chromatin, and by ...

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 350-359, June 2026.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...
