Embryonic lethality of Arabidopsis abp1-1 is caused by deletion of the adjacent BSM gene.

ABSTRACT: Decades of research have suggested that AUXIN BINDING PROTEIN 1 (ABP1) is an essential membrane-associated auxin receptor, but recent findings directly contradict this view. Here we show that embryonic lethality observed in abp1-1, which has been a cornerstone of ABP1 studies, is caused by the deletion of the neighbouring BELAYA SMERT (BSM) gene, not by disruption of ABP1. On the basis of our results, we conclude that ABP1 is not essential for Arabidopsis development.

Embryo-lethal phenotypes in early abp1 mutants are due to disruption of the neighboring BSM gene.

Project description:The Auxin Binding Protein1 (ABP1) has been identified based on its ability to bind auxin with high affinity and studied for a long time as a prime candidate for the extracellular auxin receptor responsible for mediating in particular the fast non-transcriptional auxin responses. However, the contradiction between the embryo-lethal phenotypes of the originally described Arabidopsis T-DNA insertional knock-out alleles ( abp1-1 and abp1-1s) and the wild type-like phenotypes of other recently described loss-of-function alleles ( abp1-c1 and abp1-TD1) questions the biological importance of ABP1 and relevance of the previous genetic studies. Here we show that there is no hidden copy of the ABP1 gene in the Arabidopsis genome but the embryo-lethal phenotypes of abp1-1 and abp1-1s alleles are very similar to the knock-out phenotypes of the neighboring gene, BELAYA SMERT ( BSM). Furthermore, the allelic complementation test between bsm and abp1 alleles shows that the embryo-lethality in the abp1-1 and abp1-1s alleles is caused by the off-target disruption of the BSM locus by the T-DNA insertions. This clarifies the controversy of different phenotypes among published abp1 knock-out alleles and asks for reflections on the developmental role of ABP1.

Targeted deletion of the murine apobec-1 complementation factor (acf) gene results in embryonic lethality.

Project description:apobec-1 complementation factor (ACF) is an hnRNP family member which functions as the obligate RNA binding subunit of the core enzyme mediating C-to-U editing of the nuclear apolipoprotein B (apoB) transcript. ACF binds to both apoB RNA and apobec-1, the catalytic cytidine deaminase, which then results in site-specific posttranscriptional editing of apoB mRNA. Targeted deletion of apobec1 eliminates C-to-U editing of apoB mRNA but is otherwise well tolerated. However, the functions and potential targets of ACF beyond apoB mRNA editing are unknown. Here we report the results of generating acf knockout mice using homologous recombination. While heterozygous acf(+/)(-) mice were apparently healthy and fertile, no viable acf(-)(/)(-) mice were identified. Mutant acf(-)(/)(-) embryos were detectable only until the blastocyst (embryonic day 3.5 [E3.5]) stage. No acf(-)(/)(-) blastocysts were detectable following implantation at E4.5, and isolated acf(-)(/)(-) blastocysts failed to proliferate in vitro. Small interfering RNA knockdown of ACF in either rat (apobec-1-expressing) or human (apobec-1-deficient) hepatoma cells decreased ACF protein expression and induced a commensurate increase in apoptosis. Taken together, these data suggest that ACF plays a crucial role, which is independent of apobec-1 expression, in cell survival, particularly during early embryonic development.

Decreased Expression of a Gene Caused by a T-DNA Insertion in an Adjacent Gene in Arabidopsis.

Project description:ALADIN is a component of the nuclear pore complex in higher eukaryotes. An Arabidopsis knockout line that had a T-DNA insertion in the ALADIN gene was defective in plant growth and thylakoid development and had reduced photosynthetic activity resulting from lower chlorophyll accumulation. The mutation appeared to decrease the level of chloroplast RuBisCO subunits and PSBA and PGL35 proteins. Unexpectedly, the T-DNA insertion in the ALADIN gene decreased the expression of the neighboring gene PSRP5, which functions in translation in chloroplasts. The mutant phenotype was rescued by expressing PSRP5, but not by expressing ALADIN. The abnormal phenotypes were also detected in an artificial microRNA (amiRNA)-mediated PSRPS5 knockdown, but not in an amiRNA-mediated ALADIN knockdown line. Thus, users of T-DNA insertions should be aware that a T-DNA insertion in one gene can have effects on the expression of neighboring genes.

Early embryonic lethality in mice with targeted deletion of the CTP:phosphocholine cytidylyltransferase alpha gene (Pcyt1a).

Project description:CTP:phosphocholine cytidylyltransferase (CCT) catalyzes a rate-controlling step in the biosynthesis of phosphatidylcholine (PtdCho). Multiple CCT isoforms, CCTalpha, CCTbeta2, and CCTbeta3, are encoded by two genes, Pcyt1a and Pcyt1b. The importance of CCTalpha in mice was investigated by deleting exons 5 and 6 in the Pcyt1a gene using the Cre-lox system. Pcyt1a-/- zygotes failed to form blastocysts, did not develop past embryonic day 3.5 (E3.5), and failed to implant. In situ hybridization in E11.5 embryos showed that Pcyt1a is expressed ubiquitously, with the highest level in fetal liver, and CCTalpha transcripts are significantly more abundant than transcripts encoding CCTbeta or phosphatidylethanolamine (PtdEtn) N-methyl transferase, two other enzymes capable of producing PtdCho. Reduction of the CCTalpha transcripts in heterozygous E11.5 embryos was accompanied by upregulation of CCTbeta and PtdEtn N-methyltransferase transcripts. In contrast, enzymatic and real-time PCR data revealed that CCTbeta (Pcyt1b) expression is not upregulated to compensate for the reduction in CCTalpha expression in adult liver and other tissues from Pcyt1a+/- heterozygous mice. PtdCho biosynthesis measured by choline incorporation into isolated hepatocytes was not compromised in the Pcyt1a+/- mice. Liver PtdCho mass was the same in Pcyt1a+/+ and Pcyt1a+/- adult animals, but lung PtdCho mass decreased in the heterozygous mice. These data show that CCTalpha expression is required for early embryonic development, but that a 50% reduction in enzyme activity has little detectable impact on the operation of the CDP-choline metabolic pathway in adult tissues.

Alport syndrome caused by a COL4A5 deletion and exonization of an adjacent AluY.

Project description:Mutation-induced activation of splice sites in intronic repetitive sequences has contributed significantly to the evolution of exon-intron structure and genetic disease. Such events have been associated with mutations within transposable elements, most frequently in mutation hot-spots of Alus. Here, we report a case of Alu exonization resulting from a 367-nt genomic COL4A5 deletion that did not encompass any recognizable transposed element, leading to the Alport syndrome. The deletion brought to proximity the 5' splice site of COL4A5 exon 33 and a cryptic 3' splice site in an antisense AluY copy in intron 32. The fusion exon was depleted of purines and purine-rich splicing enhancers, but had low levels of intramolecular secondary structure, was flanked by short introns and had strong 5' and Alu-derived 3' splice sites, apparently compensating poor composition and context of the new exon. This case demonstrates that Alu splice sites can be activated by outlying deletions, highlighting Alu versatility in shaping the exon-intron organization and expanding the spectrum of mutational mechanisms that introduce repetitive sequences in mRNAs.

Deletion of Mthfd1l causes embryonic lethality and neural tube and craniofacial defects in mice.

Project description:Maternal supplementation with folic acid is known to reduce the incidence of neural tube defects (NTDs) by as much as 70%. Despite the strong clinical link between folate and NTDs, the biochemical mechanisms through which folic acid acts during neural tube development remain undefined. The Mthfd1l gene encodes a mitochondrial monofunctional 10-formyl-tetrahydrofolate synthetase, termed MTHFD1L. This gene is expressed in adults and at all stages of mammalian embryogenesis with localized regions of higher expression along the neural tube, developing brain, craniofacial structures, limb buds, and tail bud. In both embryos and adults, MTHFD1L catalyzes the last step in the flow of one-carbon units from mitochondria to cytoplasm, producing formate from 10-formyl-THF. To investigate the role of mitochondrial formate production during embryonic development, we have analyzed Mthfd1l knockout mice. All embryos lacking Mthfd1l exhibit aberrant neural tube closure including craniorachischisis and exencephaly and/or a wavy neural tube. This fully penetrant folate-pathway mouse model does not require feeding a folate-deficient diet to cause this phenotype. Maternal supplementation with sodium formate decreases the incidence of NTDs and partially rescues the growth defect in embryos lacking Mthfd1l. These results reveal the critical role of mitochondrially derived formate in mammalian development, providing a mechanistic link between folic acid and NTDs. In light of previous studies linking a common splice variant in the human MTHFD1L gene with increased risk for NTDs, this mouse model provides a powerful system to help elucidate the specific metabolic mechanisms that underlie folate-associated birth defects, including NTDs.

Embryonic lethality caused by apoptosis during gastrulation in mice lacking the gene of the ADP-ribosylation factor-related protein 1.

Project description:ADP-ribosylation factor (ARF)-related protein 1 (ARFRP1) is a membrane-associated GTPase with significant similarity to the family of ARFs. We have recently shown that ARFRP1 interacts with the Sec7 domain of the ARF-specific guanine nucleotide exchange factor Sec7-1/cytohesin and inhibits the ARF/Sec7-dependent activation of phospholipase D in a GTP-dependent manner. In order to further analyze the function of ARFRP1, we cloned the mouse Arfrp1 gene and generated Arfrp1 null-mutant mice by gene targeting in embryonic stem cells. Heterozygous Arfrp1 mutants developed normally, whereas homozygosity for the mutant allele led to embryonic lethality. Cultured homozygous Arfrp1 null-mutant blastocysts were indistinguishable from wild-type blastocysts. In vivo, they implanted and formed egg cylinder stage embryos that appeared normal until day 5. Between embryonic days 6 and 7, however, apoptotic cell death of epiblast cells occurred in the embryonic ectoderm during gastrulation, as was shown by histological analysis combined with terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling. Epiblast cells that would normally differentiate to mesodermal cells detached from the ectodermal cell layer and were dispersed into the proamniotic cavity. In contrast, the development of extraembryonic structures appeared unaffected. Our results demonstrate that ARFRP1 is necessary for early embryonic development during gastrulation.

Strong morphological defects in conditional Arabidopsis abp1 knock-down mutants generated in absence of functional ABP1 protein.

Project description:The Auxin Binding Protein 1 (ABP1) is one of the most studied proteins in plants. Since decades ago, it has been the prime receptor candidate for the plant hormone auxin with a plethora of described functions in auxin signaling and development. The developmental importance of ABP1 has recently been questioned by identification of Arabidopsis thaliana abp1 knock-out alleles that show no obvious phenotypes under normal growth conditions. In this study, we examined the contradiction between the normal growth and development of the abp1 knock-outs and the strong morphological defects observed in three different ethanol-inducible abp1 knock-down mutants ( abp1-AS, SS12K, SS12S). By analyzing segregating populations of abp1 knock-out vs. abp1 knock-down crosses we show that the strong morphological defects that were believed to be the result of conditional down-regulation of ABP1 can be reproduced also in the absence of the functional ABP1 protein. This data suggests that the phenotypes in abp1 knock-down lines are due to the off-target effects and asks for further reflections on the biological function of ABP1 or alternative explanations for the missing phenotypic defects in the abp1 loss-of-function alleles.

Deletion of exon 20 of the Familial Dysautonomia gene Ikbkap in mice causes developmental delay, cardiovascular defects, and early embryonic lethality.

Project description:Familial Dysautonomia (FD) is an autosomal recessive disorder that affects 1/3,600 live births in the Ashkenazi Jewish population, and leads to death before the age of 40. The disease is characterized by abnormal development and progressive degeneration of the sensory and autonomic nervous system. A single base pair substitution in intron 20 of the Ikbkap gene accounts for 98% of FD cases, and results in the expression of low levels of the full-length mRNA with simultaneous expression of an aberrantly spliced mRNA in which exon 20 is missing. To date, there is no animal model for the disease, and the essential cellular functions of IKAP--the protein encoded by Ikbkap--remain unknown. To better understand the normal function of IKAP and in an effort to generate a mouse model for FD, we have targeted the mouse Ikbkap gene by homologous recombination. We created two distinct alleles that result in either loss of Ikbkap expression, or expression of an mRNA lacking only exon 20. Homozygosity for either mutation leads to developmental delay, cardiovascular and brain malformations, accompanied with early embryonic lethality. Our analyses indicate that IKAP is essential for expression of specific genes involved in cardiac morphogenesis, and that cardiac failure is the likely cause of abnormal vascular development and embryonic lethality. Our results also indicate that deletion of exon 20 abolishes gene function. This implies that the truncated IKAP protein expressed in FD patients does not retain any significant biological function.

Deletion of an X-inactivation boundary disrupts adjacent gene silencing.

Project description:In mammalian females, genes on one X are largely silenced by X-chromosome inactivation (XCI), although some "escape" XCI and are expressed from both Xs. Escapees can closely juxtapose X-inactivated genes and provide a tractable model for assessing boundary function at epigenetically regulated loci. To delimit sequences at an XCI boundary, we examined female mouse embryonic stem cells carrying X-linked BAC transgenes derived from an endogenous escape locus. Previously we determined that large BACs carrying escapee Kdm5c and flanking X-inactivated transcripts are properly regulated. Here we identify two lines with truncated BACs that partially and completely delete the distal Kdm5c XCI boundary. This boundary is not required for escape, since despite integrating into regions that are normally X inactivated, transgenic Kdm5c escapes XCI, as determined by RNA FISH and by structurally adopting an active conformation that facilitates long-range preferential association with other escapees. Yet, XCI regulation is disrupted in the transgene fully lacking the distal boundary; integration site genes up to 350 kb downstream of the transgene now inappropriately escape XCI. Altogether, these results reveal two genetically separable XCI regulatory activities at Kdm5c. XCI escape is driven by a dominant element(s) retained in the shortest transgene that therefore lies within or upstream of the Kdm5c locus. Additionally, the distal XCI boundary normally plays an essential role in preventing nearby genes from escaping XCI.
