Chinese hamster ovary cells overexpressing the oxysterol binding protein (OSBP) display enhanced synthesis of sphingomyelin in response to 25-hydroxycholesterol

Journal of Lipid Research, 1999
25-Hydroxycholesterol negatively regulates cholesterol synthesis and activates cholesterol esterification in a variety of cultured cells. Concurrent with these effects, 25-hydroxycholesterol also stimulates the synthesis of sphingomyelin in Chinese ...

Raft-based sphingomyelin interactions revealed by new fluorescent sphingomyelin analogs [PDF]

Journal of Cell Biology, 2017
Sphingomyelin (SM) has been proposed to form cholesterol-dependent raft domains and sphingolipid domains in the plasma membrane (PM). How SM contributes to the formation and function of these domains remains unknown, primarily because of the scarcity of suitable fluorescent SM analogs.

Secretopathies emerge as a new class of neurocristopathies

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.

Phase composition of lipoprotein SM/cholesterol/PtdCho affects FA specificity of sPLA2s

Journal of Lipid Research, 2008
We have previously reported preferential release of polyunsaturated FAs during hydrolysis of lipoprotein phosphatidylcholine (PtdCho) by group X secretory phospholipase A2 (sPLA2) and preferential release of oligounsaturated FAs during hydrolysis of ...

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Pharmacological reversion of sphingomyelin‐induced dendritic spine anomalies in a Niemann Pick disease type A mouse model

EMBO Molecular Medicine, 2014
Understanding the role of lipids in synapses and the aberrant molecular mechanisms causing the cognitive deficits that characterize most lipidosis is necessary to develop therapies for these diseases.

Exchange of phospholipid classes between liver microsomes and plasma: comparison of rat, rabbit, and guinea pig

Journal of Lipid Research, 1971
Rat and guinea pig liver microsomes labeled with phospholipid 32P were incubated with rat, guinea pig, and rabbit plasma in a KC1–Tris–EDTA buffer. A net transfer of microsomal phosphatidylcholine and phosphatidylethanolamine to plasma was observed.

The multiple hit model of infantile and epileptic spasms: The 2025 update

Epilepsia Open, EarlyView.
Abstract Objective Infantile and epileptic spasms syndrome (IESS) is a developmental and epileptic encephalopathy manifesting with epileptic spasms and poor neurodevelopmental outcomes. There is an urgent need for the development of more effective and tolerated therapies.
