Arachidonic acid (5.8,11,14-eicosatetraenoic acid C20:4, n-6) is released from the cell membrane by the action of phospholipases on membrane phospholipids. Metabolites of arachidonic acid, which are generically termed eicosanoids, including prostagla

Two cases of Werner's syndrome are reported. Fibroblasts derived from both patients revealed reduced population doubling numbers. Chromosomal analyses for fibroblasts from both patients and lymphocytes from one patient revealed that chromosomal aberr

We examined the enzymatic activity of leukotriene (LT) A4 hydrolase, which catalyzes the conversion of LTA4 to LTB4, in peripheral leukocytes of patients with atopic dermatitis. The patients were divided into three categories (severe, moderate and mi

We examined the role of rho gene products ( rho proteins) on cell growth and cytoskeleton organization in transformed human epidermal cells in culture (HSC-1), using recombinant botulinum C3 exoenzyme which specifically ADP-ribosylates rho proteins.

Background Eosinophil cationic protein (ECP) is a highly basic protein (pI over 11) with molecular weight ranging from 18.5 to 22 kDa, and is released upon eosinophil activation. ECP is stored in the eosinophil granules and has potent bactericidal, h

The importance of environmental factors such as ultraviolet light and temperature in the pathogenesis of cutaneous lupus erythematosus is well recognized. Recent evidence suggests the presence of autoantibodies to heat shock proteins (HSP) in the ser

Cyclopentenone prostaglandins (PG) such as delta 12-PGJ2 and PGA are potent inhibitors of growth in a variety of cultured cells, including human epidermal cells. To clarify the mechanism of PG cytotoxicity in human epidermal cells, we examined the ef

The activity of poly(adenosine diphosphate-ribose) (poly(ADP-ribose)) synthesis was examined in permeabilized transformed mouse epidermal cells (PAM 212 cells) in culture. PAM cells grown in low (0.02mM) Ca++ medium showed a higher activity of poly(A

We evaluated the serum levels of major basic protein (MBP), assayed using an MBP radioimmunoassay kit, and the effect of an anti-allergic agent, ketotifen, which has strong anti-eosinophil activity, in 56 atopic dermatitis (AD) patients. The serum MB
