Abstract

We present here a draft genome sequence of the red jungle fowl, Gallus gallus. Because the chicken is a modern descendant of the dinosaurs and the first non-mammalian amniote to have its genome sequenced, the draft sequence of its genome--composed of approximately one billion base pairs of sequence and an estimated 20,000-23,000 genes--provides a new perspective on vertebrate genome evolution, while also improving the annotation of mammalian genomes. For example, the evolutionary distance between chicken and human provides high specificity in detecting functional elements, both non-coding and coding. Notably, many conserved non-coding sequences are far from genes and cannot be assigned to defined functional classes. In coding regions the evolutionary dynamics of protein domains and orthologous groups illustrate processes that distinguish the lineages leading to birds and mammals. The distinctive properties of avian microchromosomes, together with the inferred patterns of conserved synteny, provide additional insights into vertebrate chromosome architecture.

Abstract

7,12-Dimethylbenz(a)anthracene (DMBA) rapidly suppresses hematopoietic progenitors, measured as colony forming units (CFU), in mouse bone marrow (BM) leading to mature cell losses as replenishment fails. These losses are mediated by Cyp1b1, independent of the AhR, despite induction of Cyp1b1. BM mesenchymal progenitor cells (MPC) may mediate these responses since basal Cyp1b1 is minimally induced. PreB colony forming unit activity (PreB CFU) is lost within 24 hours in isolated BM cells (BMC) unless cocultured with cells derived from primary MPC (BMS2 line). The mouse embryonic OP9 line, which provides more efficient coculture support, shares similar induction-resistant Cyp1b1 characteristics. This OP9 support is suppressed by DMBA, which is then prevented by Cyp1b1 inhibitors. OP9-enriched medium partially sustains CFU activities but loses DMBA-mediated suppression, consistent with mediation by OP9 Cyp1b1. PreB CFU activity in BMC from Cyp1b1-ko mice has enhanced sensitivity to DMBA. BMC gene expression profiles identified cytokines and developmental factors that are substantially changed in Cyp1b1-ko mice. DMBA had few effects in WT mice but systematically modified many clustered responses in Cyp1b1-ko mice. Typical BMC AhR-responsive genes were insensitive to Cyp1b1 deletion. TCDD replicated Cyp1b1 interventions, suggesting alternative AhR mediation. Cyp1b1 also diminishes oxidative stress, a key cause of stem cell instability. [ABSTRACT FROM AUTHOR]

17. Integration of chicken linkage and physical maps and sequence alignment using overgo hybridization

Author

Abstract

Research is underway to align the chicken genetic linkage map, defined primarily by segregation of DNA-based markers, with the BAC contig physical map (Ren et al., in press). This aids the assembly of BAC and genome sequence contigs and alignment of contigs with chicken chromosomes. Efforts to date have focused on the use of overgo oligonucleotide probes, ca. 40 nucleotide double-stranded DNAs, hybridized to BAC filter arrays. Four BAC libraries are now in use (BamHI, EcoRI, and HindIII insert libraries, Texas A&M, and CHORI-261, Children's Hospital of Oakland Research Institute, all using DNA from a single UCD001 inbred Jungle Fowl). A 6x6x6 matrix of 216 probes is employed, with each probe designed based on DNA sequence information for a specific mapped marker or gene. Hybridization is done with pools of 36 probes at a time, such that one probe is uniquely contained in a combination of 3 pools, each from a different dimension (row, column or plate). In our hands, a fourth, redundant dimension of six additional pools is desirable. All BACs assigned to chicken genes and markers have been incorporated into a database available online (http://poultry.mph.msu.edu/resources/Resources.htm#bacdata). As of October 2003, the database includes nearly 5000 BAC assignments for 577 markers across almost all chicken chromosomes and linkage groups. Overgo hybridization provides a cost-effective, high throughput method for integration of physical maps, sequences and linkage maps for domestic animal (and plant) species. Supported, in part, by the USDA/CSREES (Project numbers: 99-35205-8566 and 2001-52100-11225)

18. Alignment of the linkage map, physical map, and sequence of the chicken genome

Author

Abstract

Four BAC libraries constructed at Texas A&M University and at the Children's Hospital of Oakland Research Institute providing altogether ~28X coverage of the chicken genome have been screened with most of the suitable genes and markers that are found on the chicken genetic linkage map (Schmid et al., 2000). This has provided the means to align the chicken BAC contig physical map (Ren et al., 2003) with the linkage map and assign most contigs to their appropriate location on a chicken chromosome. It also has aided in assembly of the first draft sequence of the chicken genome. Our screening approach of choice is overgo hybridization, using four-dimensional pooling (36 probes at a time, one degree of redundancy), chosen from a matrix of 216 probes per screen. All BACs assigned to chicken genes and markers have been incorporated into a database available online (https://www.msu.edu/~dodgson/resources/resources.htm#bacdata). As of October 2003, the database includes nearly 5000 BAC assignments for 577 markers across almost all chicken chromosomes and linkage groups. On-going overgo hybridization is being used to do fine structure comparative mapping between the human and chicken genomes and to close gaps detected in the first round chicken sequence assembly. Overgo hybridization provides a cost-effective, high throughput method for integration of physical maps and linkage maps for domestic animal (and plant) species. Supported by the USDA/CSREES (Project numbers: 99-35205-8566 and 2001-52100-11225).

Abstract

Porphyria cutanea tarda (PCT) is a cutaneous porphyria with sporadic (type 1) and familial (type 2) subtypes, both resulting from decreased hepatic uroporphyrinogen decarboxylase (UROD) activity. Environmental and genetic factors are involved in the development of PCT, and genetic variants in the cytochrome P450 (CYP ) genes, CYP1A1 and CYP1A2, have been implicated. We investigated the association between PCT and variants in CYP1A1, CYP1A2 and CYP2E1, and the glutathione-S-transferase (GST ) genes, GSTM1 and GSTT1. PCT diagnosis was based on urinary or plasma porphyrin profiles. Patients were classified as type 1 or 2 PCT based on UROD mutation analysis. The CYP1A2*1F promoter A allele frequency was significantly higher (P < 0.022) and the A/A genotype frequency marginally higher in PCT patients overall (P < 0.057), with the A/A genotype significantly more common in type 1 PCT (P < 0.043). The presence of the wild-type GSTM1 allele also was associated significantly with PCT (P < 0.019). Neither hemochromatosis (HFE) mutations, tobacco smoking, hepatitis C and HIV infection, ethanol consumption, nor estrogen use were associated with these allelic variants. Age at onset was significantly lower in type 2 PCT patients (P < 0.001), as observed previously. Thus, positive associations between PCT and the CYP1A2*1F promoter A allele and A/A genotype and the wild-type GSTM1 allele indicates that these functional hepatic biotransformation enzymes are risk factors for the development of this disease.

23. FAM210B is dispensable for erythroid differentiation in adult mice.

Author

Perfetto M, Rondelli CM, Gillis S, Stratman AN, and Yien YY

Abstract

Iron plays a central role in cellular redox processes, but its ability to adopt multiple oxidation states also enables it to catalyze deleterious reactions. The requirement for iron in erythropoiesis has necessitated the evolution of mechanisms with which to handle the iron required for hemoglobinization. FAM210B was identified as a regulator of mitochondrial iron import and heme synthesis in erythroid cell culture and zebrafish models. In this manuscript, we demonstrate that while FAM210B is required for erythroid differentiation and heme synthesis under standard cell culture conditions, holotransferrin supplementation was sufficient to chemically complement the iron-deficient phenotype. As the biology of FAM210B is complex and context specific, and whole-organism studies on FAM210 proteins have been limited, we sought to unravel the role of FAM210B in erythropoiesis using knockout mice. We were surprised to discover that Fam210b -/- mice were viable and the adults did not have erythropoietic defects in the bone marrow. In contrast to studies in C. elegans, Fam210b -/- mice were also fertile. There were some modest phenotypes, such as a slight increase in lymphocytes and white cell count in Fam210b -/- females, as well as an increase in body weight in Fam210b -/- males. However, our findings suggest that FAM210B may play a more important role in cellular iron homeostasis under iron deficient conditions. Here, we will discuss the cell culture conditions used in iron metabolism studies that can account for the disparate finding on FAM210B function. Moving forward, resolving these discrepancies will be important in identifying novel iron homeostasis genes.
