Chronic glucocorticoid-rich milieu and liver dysfunction [PDF]

open access: yes, 2016
We investigated the impact of chronic hypercorticosteronemia (due to neonatal monosodium L-glutamate, MSG, and treatment) on liver oxidative stress (OS), inflammation, and carbohydrate/lipid metabolism in adult male rats.

Acid ceramidase overactivity drives ceramide loss, leading to atopic dry skin and Th2‐skewed immune polarization

open access: yesThe Journal of Pathology, Volume 269, Issue 2, Page 232-247, June 2026.
Abstract Ceramide deficiency in the stratum corneum (SC) is a key etiological factor in atopic dermatitis (AD). To clarify the direct role of SC ceramide depletion in impairing SC barrier and water‐holding functions and in initiating AD‐like skin symptoms and disease‐specific molecular alterations, we generated Tg mice overexpressing a mutant form of ...

Colorectal cancer linkage on chromosomes 4q21, 8q13, 12q24, and 15q22 [PDF]

open access: yes, 2012
A substantial proportion of familial colorectal cancer (CRC) is not a consequence of known susceptibility loci, such as mismatch repair (MMR) genes, supporting the existence of additional loci.

Metabolites involved in cellular communication among human cumulus-oocyte-complex and sperm during in vitro fertilization [PDF]

open access: yes, 2015
Background: Fertilization is a key physiological process for the preservation of the species. Consequently, different mechanisms affecting the sperm and the oocyte have been developed to ensure a successful fertilization. Thus, sperm acrosome reaction is

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

open access: yesBritish 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.

On the role of bioactive sphingolipids and their metabolizing enzymes in cancer [PDF]

open access: yes, 2017
Ceramide is a family of closely related molecules, which are presumed to be in the center of sphingolipid metabolism. Among sphingolipid metabolites, several ceramide subspecies and sphingosine induce apoptosis, cell cycle arrest and death, whereas ...

The crystal structure of human transport and Golgi organization 2 homolog (TANGO2) suggests a cysteine N‐terminal nucleophile (Ntn) hydrolase

open access: yesActa Crystallographica Section D, Volume 82, Issue 4, Page 383-396, April 2026.
This study reports the first crystal structure of human TANGO2, mutations of which are responsible for TANGO2 deficiency disorder. The crystallographic analysis demonstrates that interactions between heme and TANGO2 are nonspecific, helping to address ongoing questions about the role of TANGO2 as a heme‐trafficking protein.Recently, there has been ...

Sphingosine 1-phosphate receptors: do they have a therapeutic potential in cardiac fibrosis? [PDF]

open access: yes, 2017
Sphingosine 1-phosphate (S1P) is a bioactive lipid that is characterized by a peculiar mechanism of action. In fact, S1P, which is produced inside the cell, can act as an intracellular mediator, whereas after its export outside the cell, it can act as ...

ORMDL Proteins Turnover via Proteasome and Autophagy Is Cell‐Type Dependent and Tied to Ceramide Homeostasis

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.
