Immunomodulatory Properties of Cucumariosides from the Edible Far-Eastern Holothurian Cucumaria japonica.

Journal of medicinal food

Aminin DL, Agafonova IG, Berdyshev EV, Isachenko EG, Avilov SA, Stonik VA.
PMID: 12639406
J Med Food. 2001;4(3):127-135. doi: 10.1089/109662001753165701.

Holothurian triterpene glycosides (cucumariosides) are known to possess multiple biological activities. Here we show that cucumariosides from the Far Eastern edible holothurian (sea cucumber), Cucumaria japonica, and their semisynthetic derivatives possess potent immunomodulatory properties. Intraperitoneal injection of cucumariosides (0.2-20...

Phosphodiesterase 4 inhibitors and db-cAMP inhibit TNF-alpha release from human mononuclear cells. Effects of cAMP and cGMP-dependent protein kinase inhibitors.

Mediators of inflammation

PMID: 18475747
Mediators Inflamm. 1996;5(6):425-8. doi: 10.1155/S0962935196000580.

We investigated the effects of specific inhibitors of cAMP-dependent protein kinase (PKA) and cGMP-dependent protein kinase (PKG) on the inhibitory activity of phosphodiesterase (PDE) type 4 inhibitors and of the cell permeable analogue of cAMP, db-cAMP on LPS-induced TNF-alpha...

Ceramide and sphingosine-1 phosphate in COPD lungs.

Thorax

Berdyshev EV, Serban KA, Schweitzer KS, Bronova IA, Mikosz A, Petrache I.
PMID: 33514670
Thorax. 2021 Jan 29; doi: 10.1136/thoraxjnl-2020-215892. Epub 2021 Jan 29.

Studies of chronic obstructive pulmonary disease (COPD) using animal models and patient plasma indicate dysregulation of sphingolipid metabolism, but data in COPD lungs are sparse. Mass spectrometric and immunostaining measurements of lungs from 69 COPD, 16 smokers without COPD...

Particulate matter causes skin barrier dysfunction.

JCI insight

Kim BE, Kim J, Goleva E, Berdyshev E, Lee J, Vang KA, Lee UH, Han S, Leung S, Hall CF, Kim NR, Bronova I, Lee EJ, Yang HR, Leung DY, Ahn K.
PMID: 33497363
JCI Insight. 2021 Mar 08;6(5). doi: 10.1172/jci.insight.145185.

The molecular mechanisms that underlie the detrimental effects of particulate matter (PM) on skin barrier function are poorly understood. In this study, the effects of PM2.5 on filaggrin (FLG) and skin barrier function were investigated in vitro and in...

Methodological Considerations for Lipid and Polar Component Analyses in Human Skin Stratum Corneum.

Collection of skin very top layer, called stratum corneum, by tape stripping and the analysis of stratum corneum components by mass spectrometry provides multiple advantages for clinical studies that aim to understand the origins of allergic skin diseases and...

The roles of sphingosine kinase 1 and 2 in regulating the metabolome and survival of prostate cancer cells.

Biomolecules

Tonelli F, Alossaimi M, Natarajan V, Gorshkova I, Berdyshev E, Bittman R, Watson DG, Pyne S, Pyne NJ.

Biomolecules. 2013 Jun 10;3(2):316-33. doi: 10.3390/biom3020316.

We have previously shown that treatment of androgen-sensitive LNCaP cells with the sphingosine kinase (SK) inhibitor SKi (2-(p-hydroxyanilino)-4-(p-chlorophenyl)thiazole) induces the proteasomal degradation of two N-terminal variants of SK1 (SK1a and SK1b), increases C22:0-ceramide and diadenosine 5',5'''-P1,P3-triphosphate (Ap3A) and reduces...

Nuclear Sphingosine-1-phosphate Lyase Generated ∆2-hexadecenal is A Regulator of HDAC Activity and Chromatin Remodeling in Lung Epithelial Cells.

Cell biochemistry and biophysics

Ebenezer DL, Ramchandran R, Fu P, Mangio LA, Suryadevara V, Ha AW, Berdyshev E, Van Veldhoven PP, Kron SJ, Schumacher F, Kleuser B, Natarajan V.
PMID: 34085165
Cell Biochem Biophys. 2021 Sep;79(3):575-592. doi: 10.1007/s12013-021-01005-9. Epub 2021 Jun 03.

Sphingosine-1-phosphate (S1P), a bioactive lipid mediator, is generated from sphingosine by sphingosine kinases (SPHKs) 1 and 2 and is metabolized to ∆2-hexadecenal (∆2-HDE) and ethanolamine phosphate by S1P lyase (S1PL) in mammalian cells. We have recently demonstrated the activation...
