Retinoic acid receptors (RARs) and retinoid X receptors (RXRs) regulate transcription by binding to response elements in target genes that generally consist of two direct repeat half-sites of consensus sequence AGGTCA (ref. 1). RAR/RXR heterodimers activate transcription in response to all-trans or 9-cis retinoic acid by binding to direct repeats spaced by(More)
The term "epidermal nevus syndrome" (ENS) has been used to describe the association of epidermal hamartomas and extra-cutaneous abnormalities. Epidermal nevi follow the lines of Blaschko. The majority of the extra-cutaneous manifestations involve the brain, eye, and skeletal systems. Several subsets with characteristic features have been delineated(More)
Thapsigargin, a non-phorbol-ester-type tumor promoter, discharges intracellular Ca2+ stores by specific inhibition of the endoplasmic reticulum Ca(2+)-ATPase. We used this drug to analyze the involvement of Ca2+ and Ca(2+)-ATPases in the control of growth- and transformation-related genes. Here we show that treatment of mouse NIH 3T3 fibroblasts with(More)
We have identified rat cDNA clones that encode a POU domain protein, referred to as brain-5 (Brn-5). During embryogenesis in the rat, Brn-5 is widely expressed with highest levels in the developing brain and spinal cord from embryonic day 12.5. In the adult, Brn-5 mRNA is most abundant in the brain, where it is diffusely expressed with the exception of an(More)
Human myeloid leukemia cells, such as HL60, U937, and THP1 cells, undergo macrophage differentiation and growth arrest following treatment with the phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA). Surprisingly, we find that growth of a significant percentage of THP1 cells is arrested in the G2 phase of the cell cycle. G2 arrest correlates with(More)
OBJECTIVES The authors assessed the efficacy of a ceramide-dominant, triple-lipid barrier repair formulation (EpiCeram), which designed to correct the lipid-biochemical abnormalities in atopic dermatitis (AD) in comparison to fluticasone propionate cream. METHODS In a five-center, investigator-blinded, randomized trial, EpiCeram was compared to(More)
OBJECTIVES Clinical scores used to assess the severity of atopic dermatitis (AD) rely entirely on subjective criteria to evaluate the severity of lesions and the extent of involvement. The aim of this study was to develop an objective measure of AD severity by measuring stratum corneum (SC) functions and by using computer-assisted estimates of involved body(More)
Retinoic acid (RA) is capable of inducing the differentiation of various myelomonocytic cell lines. During this differentiation process, the levels of c-myb expression decline, suggesting that the RA receptor (RAR) may act in part by down-regulating this proto-oncogene. We have now investigated whether the RAR can also inhibit the function of Myb proteins(More)
Epidermal barrier function is abnormal in individuals with atopic dermatitis (AD). It is controversial whether primary epidermal barrier abnormalities alone account for the physiological and clinical abnormalities found in those persons with AD or whether the observed barrier dysfunction is a consequence of primary immunologic abnormalities. Recent evidence(More)
