The structural requirements for ceramide activation of serine-threonine protein phosphatases

Journal of Lipid Research, 2004
The protein phosphatases1 (PP1) and 2A (PP2A) serve as ceramide-activated protein phosphatases (CAPP). In this study, the structural requirements for interaction between ceramide and CAPP were determined.

Long chain ceramides raise the main phase transition of monounsaturated phospholipids to physiological temperature

Scientific Reports, 2022
Little is known about the molecular mechanisms of ceramide-mediated cellular signaling. We examined the effects of palmitoyl ceramide (C16-ceramide) and stearoyl ceramide (C18-ceramide) on the phase behavior of 1-palmitoyl-2-oleoyl-sn-glycero-3 ...

Ceramide in the prostate [PDF]

Cancer Biology & Therapy, 2013
The nomenclature for the serine/threonine protein phosphatases was established by Professor Sir Philip Cohen over 30 years ago. (1) At that time protein phosphatase 1 was known to have two small inhibitory proteins (I-1 and I-2) and be regulated by sub-cellular location whereas no protein inhibitor had yet been discovered for the related multi-subunit ...

Brain ceramide hexosides in Tay-Sachs disease and generalized gangliosidosis (GM1-gangliosidosis)

Journal of Lipid Research, 1967
The carbohydrate composition was determined for ceramide hexosides isolated from brains of patients with Tay-Sachs disease and generalized gangliosidosis (hereby named GM1-gangliosidosis).Gray matter of patients with each disease showed a characteristic ...

The glucocorticoid-Angptl4-ceramide axis induces insulin resistance through PP2A and PKCζ. [PDF]

, 2017
Chronic glucocorticoid exposure is associated with the development of insulin resistance. We showed that glucocorticoid-induced insulin resistance was attenuated upon ablation of Angptl4, a glucocorticoid target gene encoding the secreted protein ...

Exosomes from Human Adipose Tissue-Derived Mesenchymal Stem Cells Promote Epidermal Barrier Repair by Inducing de Novo Synthesis of Ceramides in Atopic Dermatitis. [PDF]

, 2020
Atopic dermatitis (AD) is a multifactorial, heterogeneous disease associated with epidermal barrier disruption and intense systemic inflammation. Previously, we showed that exosomes derived from human adipose tissue-derived mesenchymal stem cells (ASC ...

Targeting a ceramide double bond improves insulin resistance and hepatic steatosis

Science, 2019
Ceramides in focus Excess calorie intake can ultimately lead to a metabolic syndrome that interferes with fat or lipid metabolism. There are many different types of lipids, and it has been widely debated which are the true culprits underlying metabolic ...

Ceramide synthesis in the endoplasmic reticulum can permeabilize mitochondria to proapoptotic proteins

Journal of Lipid Research, 2008
Increased mitochondrial ceramide levels are associated with the initiation of apoptosis. There is evidence that ceramide is causal. Thus, the conversion of the precursor, dihydroceramide, to ceramide by the enzyme dihydroceramide desaturase may be ...

Downregulation of ceramide synthase 1 promotes oral cancer through endoplasmic reticulum stress

International Journal of Oral Science, 2021
C18 ceramide plays an important role in the occurrence and development of oral squamous cell carcinoma. However, the function of ceramide synthase 1, a key enzyme in C18 ceramide synthesis, in oral squamous cell carcinoma is still unclear. The aim of our

Development and validation of a ceramide- and phospholipid-based cardiovascular risk estimation score for coronary artery disease patients.

European Heart Journal, 2019
AIMS Distinct ceramide lipids have been shown to predict the risk for cardiovascular disease (CVD) events, especially cardiovascular death. As phospholipids have also been linked with CVD risk, we investigated whether the combination of ceramides with ...
