Altered Levels of Sphingosine and Sphinganine in Psoriatic Epidermis

Moon SH, Kim JY, Song EH, Shin MK, Cho YH, Kim NI

BACKGROUND: Ceramides are the main lipid component of the stratum corneum and are a structurally heterogeneous and complex group of sphingolipids of which sphingoid bases are the basic structural constituents....

Cytotoxic Activity and Structure Activity Relationship of Ceramide Analogues in Caki-2 and HL-60 Cells

Kim YJ, Kim EA, Sohn UD, Yim CB, Im C

B13, a ceramide analogue, is a ceramidase inhibitor and induces apoptosis to give potent anticancer activity. A series of thiourea B13 analogues was evaluated for their in vitro cytotoxic activities...

Cytotoxicities and Quantitative Structure Activity Relationships of B13 Sulfonamides in HT-29 and A549 Cells

Lee SK, Park SM, Im C

B13 analogues are being considered as therapeutic agents for cancer cells, since B13 is a ceramide analogue and inhibits ceramidase to promote apoptosis in cancer cells. B13 sulfonamides are assumed...

Dietary effect of red ginseng extracts mixed with torilis fructus and corni fructus on the epidermal levels of ceramides and ceramide related enzyme proteins in uv-induced hairless mice

Lee YJ, Oh IG, Cho Y

UV-irradiation is a major factor of photo-aged skin, by which pigmentation, wrinkles and laxity are increased. In addition, the epidermal barrier is disrupted, ultimately causing dryness in photo-aged skin. As...

Comparative effect of dietary borage oil and safflower oil on anti-proliferation and ceramide metabolism in the epidermis of essential fatty acid deficient guinea pigs

Lee SR, Cho Y

PURPOSE: Borage oil (BO) and safflower oil (SO) are efficacious in reversing epidermal hyperproliferation, which is caused by the disruption of epidermal barrier. In this study, we compared the antiproliferative...

A Study on Altered Expression of Serine Palmitoyltransferase and Ceramidase in Psoriatic Skin Lesion

Hong KK, Cho HR, Ju WC, Cho Y, Kim NI

Ceramides are the main lipid component maintaining the lamellae structure of stratum corneum, as well as lipid second messengers for the regulation of cellular proliferation and/or apoptosis. In our previous...
