Abstract
BACKGROUND Maternal alcohol consumption has been associated with an increased risk of nonsyndromic oral clefts in some studies. Study of gene-environment interaction may provide insight into the reasons for their discrepancies observed. We focused on a polymorphism of the ADH1C gene (third gene of the class I alcohol dehydrogenase family), involved in the metabolism of ethanol and other alcohols. METHODS Data come from a French case-control study (1998-2001), which tested the association between maternal alcohol consumption during the first trimester of pregnancy and the risk of nonsyndromic oral clefts (240 cases, 236 controls). A case-parent study design looked at the association with an ADH1C polymorphism (Ile349Val site) and potential gene-environment interaction effects. A log-linear model was used to distinguish the direct effect of the child's genotype from the maternally mediated effects. RESULTS An increased risk of nonsyndromic oral clefts was observed for women who reported drinking alcohol during the first trimester, compared with women who did not. The mutated ADH1C allele carried by the child seemed to have a protective effect against the risk of oral clefts (RRone copy, 0.71; 95% confidence interval [CI], 0.50-1.02; RRtwo copies, 0.63; 95% CI, 0.3-1.3). The maternal genotype played a less important role than the child's, and its action remains unclear. No significant evidence of interaction effects between the ADH1C genotype and maternal alcohol consumption was observed. CONCLUSIONS Because the ADH1C gene is involved in the metabolic pathways of many alcohols, we propose several hypotheses about the causal pathway, including ethanol oxidation activity and, more probably, retinol oxidation.

Abstract
The mouse Adh1 gene exhibits tissue-specific regulation, is developmentally regulated, and is androgen regulated in kidney and adrenal tissue. To study this complex regulation phenotype a transgenic mouse approach has been used to investigate regulatory regions of the gene necessary for proper tissue expression and hormonal control. Transgenic mice have been produced with an Adh1 minigene as a reporter behind either 2.5- or 10 kb of 5'-flanking sequence [1]. Complete androgen regulation in kidney requires a region between -2.5 and -10 kb. A sequence extending to -10 kb does not confer liver expression in this minigene construct. B6.S mice express an electrophoretically variant protein resulting from a known nucleotide substitution resulting in a restriction endonuclease length polymorphism. Transgenic mice harboring B6.S cosmids can be studied for expression analysis at both protein and mRNA levels, identification of transgenic founders and inheritance studies are greatly facilitated by a PCR-restriction endonuclease cleavage approach, the entire mouse gene is used as a reporter, and the formation of heterodimeric enzyme molecules can be used to infer expression of the transgene in the proper cell types within a given tissue. Expression of a B6.S cosmid containing the entire Adh1 gene and 6 kb of 5'- and 21 kb of 3'-flanking region occurs in transgenic mice in a copy number dependent manner in a number of tissues, but expression in liver does not occur. The ability to analyze expression at the protein and mRNA levels has been confirmed using this system. Future directions will involve the use of large BAC clones modified by RARE cleavage to identify the liver specific elements necessary for expression.

Abstract
This review focuses on the regulation of the mammalian medium-chain alcohol dehydrogenase (ADH) genes. This family of genes encodes enzymes involved in the reversible oxidation of alcohols to aldehydes. Interest in these enzymes is increased because of their role in the metabolism of beverage alcohol as well as retinol, and their influence on the risk for alcoholism. There are six known classes ADH genes that evolved from a common ancestor. ADH genes differ in their patterns of expression: most are expressed in overlapping tissue-specific patterns, but class III ADH genes are expressed ubiquitously. All have proximal promoters with multiple cis-acting elements. These elements, and the transcription factors that can interact with them, are being defined. Subtle differences in sequence can affect affinity for these factors, and thereby influence the expression of the genes. This provides an interesting system in which to examine the evolution of tissue specificity. Among transcription factors that are important in multiple members of this gene family are the C/EBPs, Sp1,USF, and AP1, HNF-1, CTF/NF-1, glucocorticoid, and retinoic acid receptors, and several as-yet unidentified negative elements, are important in at least one of the genes. There is evidence that cis-acting elements located far from the proximal promoter are necessary for proper expression. Three of the genes have upstream AUGs in the 5' nontranslated regions of their mRNA, unusual for mammalian genes. The upstream AUGs have been shown to significantly affect expression of the human ADH5 gene.

Abstract
This article presents a model that integrates the functions of retinoid-binding proteins with retinoid metabolism. One of these proteins, the widely expressed (throughout retinoid target tissues and in all vertebrates) and highly conserved cellular retinol-binding protein (CRBP), sequesters retinol in an internal binding pocket that segregates it from the intracellular milieu. The CRBP-retinol complex appears to be the quantitatively major form of retinol in vivo, and may protect the promiscuous substrate from nonenzymatic degradation and/or non-specific enzymes. For example, at least seven types of dehydrogenases catalyze retinal synthesis from unbound retinol in vitro (NAD+ vs. NADP+ dependent, cytosolic vs. microsomal, short-chain dehydrogenases/reductases vs. medium-chain alcohol dehydrogenases). But only a fraction of these (some of the short-chain de-hydrogenases/reductases) have the fascinating additional ability of catalyzing retinal synthesis from CRBP-bound retinol as well. Similarly, CRBP and/or other retinoid-binding proteins function in the synthesis of retinal esters, the reduction of retinal generated from intestinal beta-carotene metabolism, and retinoic acid metabolism. The discussion details the evidence supporting an integrated model of retinoid-binding protein/metabolism. Also addressed are retinoid-androgen interactions and evidence incompatible with ethanol causing fetal alcohol syndrome by competing directly with retinol dehydrogenation to impair retinoic acid biosynthesis.

Abstract
Studies on retinoid signaling indicate that much of the regulation of this pathway may involve enzymes that synthesize the active ligand retinoic acid. Alcohol dehydrogenases ADH1 (class I ADH) and ADH4 (class IV ADH) function as retinol dehydrogenases in the oxidation of retinol, a necessary step in the synthesis of retinoic acid from vitamin A. These enzymes as well as retinoic acid have previously been localized in the adult adrenal gland, thus providing evidence that this organ is an endocrine source of retinoic acid. Here, we have examined the involvement of ADH1 and ADH4 in embryonic adrenal function by using transgenic mouse technology and immunohistochemistry. Transgenic mice were generated that contain various portions of the mouse ADH4 promoter and 5'-flanking region fused to lacZ. Embryos harboring a construct containing 9.0 kb of 5'-flanking region displayed very high levels of lacZ expression in the developing adrenal blastemas at embryonic stage E11.5 during the initial phase of mouse adrenal gland development. The presence of endogenous ADH4 protein in stage E11.5 adrenal blastemas was demonstrated by immunohistochemistry, and this was the only site of ADH4 immunodetection in stage E11.5 embryos. Endogenous ADH1 protein was also detected by immunohistochemistry in stage E11.5 adrenal blastemas. ADH1 and ADH4 proteins were detectable at later stages of adrenal development, and both were localized to developing adrenal cortical cells by stage E14.5. The presence of both ADH1 and ADH4 retinol dehydrogenases during the earliest stages of adrenal gland development, combined with our earlier findings of high levels of retinoic acid in the embryonic adrenal gland, suggests that one of the earliest functions of ADH may be to provide an embryonic endocrine source of retinoic acid for growth and development.

Abstract
Programmed cell death or apoptosis is an essential process during the morphogenesis of a large number of structures. Evidence obtained over the past few years indicates that, in some cases, the generation of reactive oxygen species (ROS) is an important event during the course of apoptosis. Using an in vitro culture system in which digit individualization of developing limbs normally occurs, we assayed the effect of different antioxidants on the cell death that takes place at interdigits. The addition of phenol, dimethyl sulfoxide, or 2',7'-dichlorodihydrofluorescein diacetate (DCDHF-DA) to murine developing limbs in culture prevented digit individualization as well as the typical interdigital cell death. Two ROS-sensitive dyes, 3-(4,5-dimethylthiazol)-2,5-diphenyl tetrazolium bromide and DCDHF-DA, stained interdigits and the so-called "necrotic zones," implying that they contain cells under oxidative stress. Very few interdigital cells were doubly stained with the ROS probes and two cell death indicators (i.e., acridine orange and propidium iodide), suggesting that they detect a different stage during the course of apoptosis. Furthermore, we found cells stained for ROS that did not express a specific macrophage marker and in a few cases were seen surrounded by a macrophage. Surprisingly, many regions of the midgestation mouse embryo that are undergoing cell death correlated with those that have a markedly higher level of ROS. Our data suggest that the generation of oxidative stress is a common requirement for cell death that occurs during mouse embryonic development.

Abstract
The expression profile of the mouse Adh-1 gene, which encodes class I alcohol dehydrogenase enzyme (ADH), is complex and includes tissue specificity and differential hormone responsiveness. Whereas kidney Adh-1 transcription rate is stimulated six- to sevenfold by testosterone treatment, adrenal gland ADH-1 mRNA is reduced to less than 5% of control level within 18 h following hormone administration. Androgen receptor is required for both responses since neither occurs in Tfm mutant mice lacking receptor. Hormonal and tissue-specific aspects of Adh-1 regulation were studied in transgenic mice harboring either of two constructs containing either -2.5 kb or -10 kb of 5'-flanking sequence attached to an Adh-1 minigene. The minigene transcript was expressed in kidney and adrenal tissues, but not liver, in five independent lines harboring a transgene with -2.5 kb of 5'-flanking sequence. Androgen treatment repressed the level of the minigene transcript in adrenal gland, but did not cause induction in kidney. In four lines of transgenic mice carrying the construct with -10 kb of 5'-flanking sequence, the minigene transcript was both repressed in adrenal and induced in kidney by testosterone. These lines have no detectable transgene expression in liver tissue. The -10 kb region in the mouse Adh-1 gene contains necessary controlling regions for proper tissue expression and hormonal regulation in kidney and adrenal; however, this region does not contain all essential elements necessary for expression in liver.

Abstract
To understand the mechanisms regulating the tissue non-specific alkaline phosphatase (TNAP) activity during development, we characterized cis-transcriptional regulatory elements. In embryonic cells and tissues, TNAP expression was driven preferentially by the exon 1A (E1A) promoter, one of the two promoters previously defined. Transcriptional activity of E1A promoter was up-regulated by retinoic acid (RA) through a putative RA-responsive element. Transgenic mice analysis with lacZ reporter constructs revealed negative regulatory elements within 8.5 kb of E1A promoter. Promoter sequences of endogenous TNAP in non-expressing tissues and those carried by the 8.5 kb-lacZ transgene were found to be highly methylated. A 1 kb fragment of E1A promoter increased the methylation level of lacZ and promoter sequences. The role of RA and DNA methylation in defining the embryonic expression pattern of TNAP is discussed.

Abstract
Multiple forms of vertebrate alcohol dehydrogenase (ADH) have been identified, but only one form, class III ADH, has been conserved in all organisms studied. Class III ADH functions in vitro as a glutathione-dependent formaldehyde dehydrogenase, which suggests that this was the original function that drove the evolution of ADH. Genetic analysis of class III ADH in yeast supports this view, but such studies are lacking in higher eukaryotes. The mouse ADH family has been previously analyzed and it contains three forms of ADH including the class III enzyme. We have initiated a molecular genetic analysis of the mouse class III ADH gene (Adh-2) by screening a genomic library with a full-length cDNA. Two overlapping clones contained the complete Adh-2 gene composed of nine exons in a 12-kb region, with the placement of introns matching that observed in other mammalian ADH genes. In this screening, we also isolated a clone (psi Adh-2) that lacks introns and which resembles a processed pseudogene. psi Adh-2 contained 25 point mutations relative to the previously analyzed Adh-2 cDNA, but still retained an intact open reading frame. Northern blot analysis using gene-specific probes provided evidence that psi Adh-2 does not produce a mRNA in either liver or kidney, whereas Adh-2 does. The functionality of the two genes was also compared by fusion of their 5'-flanking regions to a lacZ reporter gene. Reporter gene expression following transfection into mouse F9 embryonal carcinoma cells indicated that only Adh-2 possesses promoter activity.

Abstract
Fetal alcohol syndrome (FAS) refers to a pattern of birth defects occurring in a subpopulation of children born to women who consume alcohol during pregnancy. The significant medical, social, and economic impact of FAS is increasing. Particularly hard-hit are African-American and native-American women and children. Over the past two decades, basic and clinical research produced voluminous data on ethanol effects on developing organisms. In 1991, Duester and Pullarkat proposed that competition of ethanol with retinol at the alcohol dehydrogenase (ADH) binding site formed the basis of the FAS mechanism. This competition adversely affects the developing fetus caused by deregulation of retinoic acid (RA) homeostasis essential for proper fetal tissue development. Stated concisely, the FAS hypothesis is: 1. Class I ADH catalyzes the rate-limiting step in oxidation of retinol (ROH) to RA, and ethanol (ETOH) to acetic acid, thus establishing competition for ADH between ROH and ETOH. 2. RA is required as a signal molecule for cell differentiation critical for normal fetal morphogenesis. 3. ADH binds ingested ETOH, thus deregulating RA homeostasis leading to improper RA signal transduction. Preliminary results from molecular modeling studies of ROH-ADH and ETOH-ADH structures, and physiologic pharmacokinetic modeling confirm the hypothesis with remarkable fidelity.
