Abstract
Fatty acid-binding proteins (FABP) belong to a superfamily of lipid binding proteins that exhibit a high affinity for long chain fatty acids and appear to function in metabolism and intracellular transportation of lipids. The current study was designed to investigate the effects of heart (H)-FABP gene on chicken growth and body composition traits. The Northeast Agricultural University divergent broiler lines for abdominal fat and a broiler X silkie F2 population were used in this study. Body weight and body composition traits were measured in the populations. Primers were designed according to the chicken H-FABP gene sequence. Polymorphisms between parental lines were detected by DNA sequencing. PCR-RFLP and PCR-fragment length polymorphism methods were developed to genotype the populations. The results showed that the H-FABP gene polymorphisms in the two populations were associated with abdominal fat percentage. It implied that H-FABP gene can be a candidate locus or linked to a major gene(s) that affects abdominal fat content in the chicken.

Abstract
Teleost fishes differ from mammals in their fat deposition and distribution. The gene for adipocyte-type fatty acid-binding protein (A-FABP or FABP4) has not been identified thus far in fishes. We have determined the cDNA sequence and defined the structure of a fatty acid-binding protein gene (designated fabp4) from the zebrafish genome. The polypeptide sequence encoded by zebrafish fabp4 showed highest identity to the H(ad)-FABP or H6-FABP from Antarctic fishes and the putative orthologs from other teleost fishes (83-88%). Phylogenetic analysis clustered the zebrafish FABP4 with all Antarctic fish H6-FABPs and putative FABP4s from other fishes in a single clade, and then with the mammalian FABP4s in an extended clade. Zebrafish fabp4 was assigned to linkage group 19 at a distinct locus from fabp3. A number of closely linked syntenic genes surrounding the zebrafish fabp4 locus were found to be conserved with human FABP4. The zebrafish fabp4 transcripts showed sequential distribution in the developing eye, diencephalon and brain vascular system, from the middle somitogenesis stage to 48 h postfertilization, whereas fabp3 mRNA was located widely in the embryonic and/or larval central nervous system, retina, myotomes, pancreas and liver from middle somitogenesis to 5 days postfertilization. Differentiation in developmental regulation of zebrafish fabp4 and fabp3 gene transcription suggests distinct functions for these two paralogous genes in vertebrate development.

Abstract
Heart fatty acid binding protein (hFABP) is a novel small cytosolic protein that is abundant in the heart. It is highly cardiac-specific (i.e. expressed primarily in cardiac tissue), but is also expressed at low concentrations in tissues outside the heart. After myocardial ischemic damage, hFABP can be detected in the blood as early as 1-3 h after onset of chest pain, with peak values reached at 6-8 h and plasma levels returning to normal within 24-30 h. hFABP's clinical diagnostic value is very limited in the presence of renal failure and skeletal muscle diseases as it is completely renally eliminated. In these conditions, the diagnosis of acute myocardial infarction (AMI) may be overestimated. The combination of initial hFABP release after symptom onset, rapid kidney clearance from the circulation and high cardiac specificity suggests great potential for clinical use. Serial measurements of hFABP in the first 24 h after onset of symptoms in AMI patients can: (a) identify patients who are susceptible to reperfusion strategies, (b) detect perioperative AMIs, (c) distinguish patients who reperfuse their infarct-related artery from those who do not, as early as 30 min after starting thrombolytic treatment, (d) detect re-infarction if it occurs within 10 h after symptom onset, and (e) permit an accurate estimation of myocardial infarct size providing important prognosis information.

Abstract
Fatty acid-binding proteins (FABPs) are members of the superfamily of lipid-binding proteins (LBP). So far 9 different FABPs, with tissue-specific distribution, have been identified: L (liver), I (intestinal), H (muscle and heart), A (adipocyte), E (epidermal), Il (ileal), B (brain), M (myelin) and T (testis). The primary role of all the FABP family members is regulation of fatty acid uptake and intracellular transport. The structure of all FABPs is similar - the basic motif characterizing these proteins is beta-barrel, and a single ligand (e.g. a fatty acid, cholesterol, or retinoid) is bound in its internal water-filled cavity. Despite the wide variance in the protein sequence, the gene structure is identical. The FABP genes consist of 4 exons and 3 introns and a few of them are located in the same chromosomal region. For example, A-FABP, E-FABP and M-FABP create a gene cluster. Because of their physiological properties some FABP genes were tested in order to identify mutations altering lipid metabolism. Furthermore, the porcine A-FABP and H-FABP were studied as candidate genes with major effect on fatness traits.

Abstract
Heart fatty-acid-binding protein (FABP) is a small cytosolic protein that is abundant in the heart and has low concentrations in the blood and in tissues outside the heart. It appears in the blood as early as 1.5 h after onset of symptoms of infarction, peaks around 6 h and returns to baseline values in 24 h. These features of H-FABP make it an excellent potential candidate for the detection of acute myocardial infarction (AMI). We review the strengths and weaknesses of H-FABP as a clinically applicable marker of myocyte necrosis in the context of acute coronary syndromes.

Abstract
The fatty acid-binding proteins (FABPs) constitute a conserved group of cytosolic low molecular mass proteins, which consists of several types: liver, heart, myelin, epidermal, adipocyte, brain, intestinal and ileal type. The FABP gene structure is well conserved during evolution and exhibits a four-exon/three-intron structure. In the past, multiple hybridizing fragments were detected upon Southern blot analysis using heart FABP (H-FABP) cDNA as a probe. The origin of these fragments was not clear. We screened a human genomic library and isolated an intronless gene (FABP3-ps) with 85% similarity to the human H-FABP cDNA and high similarity (76 and 79%) to the H-FABP cDNAs of mouse and bovine, respectively. By means of fluorescence in situ hybridization this processed pseudogene could be assigned chromosome 13q13-q14, whereas the gene for human H-FABP (FABP3) resides on chromosome 1p32-p33. No expression of the processed pseudogene could be detected in skeletal muscle or fetal brain.

Abstract
The purpose of this study was to detect genetic variation in the porcine H-FABP gene, a candidate gene for meat quality traits in pigs. Lambda phages containing the porcine H-FABP gene were isolated by plaque hybridization with human H-FABP cDNA. The coding and flanking intronic sequences of the porcine H-FABP gene were determined as well as 1.6 kb of the 5' upstream region. The various potential regulatory sequences in this region are in accordance with the function and expression of the protein in muscle and mammary tissue. Furthermore, comparison with the homolog region of the mouse identified a highly conserved 13-bp element (CTTCCT [A/C] TTTCGG) that may be involved in regulation of expression. The porcine H-FABP gene was localized on Chromosome (Chr) 6 by porcine sequence-specific PCR on DNA from a pig/rodent cell hybrid panel. In addition, part of the H-FABP gene was screened for genetic variation by PCR-RFLP analysis. Three PCR-RFLPs were detected, one in the upstream region (HinfI) and two in the second intron (HaeIII and MspI). In most pig breeds the corresponding alleles have a variable distribution, possibly a consequence of selective breeding. This genetic variation will enable us to investigate the role of the H-FABP locus in porcine production and meat quality traits.

Abstract
A single-gene rodent mutation (diabetes) and a quantitative trait locus (dietary obese 1) mapped to the mid portion of mouse chromosome 4 have been related to obesity and/or insulin levels. Synteny relationships place their putative human homologs on 1p31 and 1p35-p31, respectively. In 137 sibships of adult brothers and sisters from the Québec Family Study, genetic linkages between seven microsatellite markers from 1p32-p22 and various obesity- and diabetes-related quantitative phenotypes were examined using single locus sibpair linkage analysis. Suggestive linkages were observed between markers D1S476 and body mass index (p = 0.05), fat mass (p = 0.02), the sum of six skinfolds (p = 0.02), the insulin area after an oral glucose tolerance test (p = 0.02), and between the neighboring marker D1S200 and body mass index (p = 0.03), and fat mass (p = 0.009). Suggestive linkages were also observed between the more telomeric markers D1S193 and body mass index (p = 0.03), and between the neighboring marker D1S197 and fasting insulin level (p = 0.05). No linkage was observed with the trunk to extremity skinfolds ratio. These linkages suggest that human homologs of the mouse diabetes or dietary obese 1 and/or other genes in this interval on chromosome 1 play a role in the regulation of body mass, body composition, and insulin levels, but not of subcutaneous fat distribution.

Abstract
A lens epithelial (LE) cell cDNA clone, designated pLELBP, was isolated by subtraction-hybridization methods between a 4-week-old rat LE cell and rat lens fiber cell lambda ZAP cDNA libraries. The cDNA contained 683 bp, an ATG at bp 42, and an open reading frame (ORF) encoding a protein of 135 amino acids (aa), and a poly(A) signal at bp 641 (GenBank/EMBL accession No. U13253). Northern blot analysis showed that the lens mRNA was at a concentration that exceeded 100-fold that found in non-ocular tissues examined, except in skin it was found at levels equal to about 1/15 of the lens levels. In the retina, it was also found at about 1/15 of that present in the lens. By in situ hybridization analysis, the sense RNA was localized to the LE cells and to the glial cells of the retina, and negligibly to the lens fiber cells. Search of GenBank, EMBL and SwissProt data bases revealed that the LE cell mRNA and its aa encoded protein showed extensive sequence homology to members of the cytosolic lipid-binding protein (LBP) family. It matched to 91% in aa sequence homology to the protein encoded by ORF of mal1 cDNA, isolated from mouse skin squamous cell carcinoma [Krieg et al., J. Biol. Chem. 268 (1993) 17362-17369], and 99% in aa sequence homology to the protein encoded by ORF of rat skin LBP mRNA [Watanabe et al., Biochem. Biophys. Res. Commun. 200 (1994) 253-259]. Occurrence of high levels of mRNA for a specific LBP in the LE cells relative to other non-ocular tissues is consistent with a hypothesis that the encoded protein may be involved in several lens epithelial cell-specific mechanisms, possibly including differentiation, protective and nutritional processes.
