Genome duplication is tightly controlled in multicellular organisms to ensure the genome stability. Studies in Saccharomyces cerevisiae and Xenopus show that minichromosome maintenance (MCM) proteins are essential for genome duplication. However, the development role of MCM proteins in multicellular organisms is not well known. MCM5 encodes a member of the MCM2-7 protein family involved in the initiation of DNA replication. The sequences of all Mcm5 homologues from yeast to human are highly conserved and suggest that their functions are also conserved. Here, we isolated the first mutant allele of mcm-5 (fw7) in Caenorhabditis elegans. Homozygous mcm-5 (fw7) mutants from heterozygous parents exhibited variable larval lethality and adult sterility. The postembryonically born neuron number was decreased and also showed aberrant axon morphology. Our study revealed that the losses of neurons in mcm-5 (fw7) mutants were caused by cell cycle defects not by programmed cell death. The examination showed that mcm-5 was widely used for postembryonic development in multiple cells such as seam cells, gonad and intestinal cells. Knockdown of mcm-5 by RNAi caused 98.1% embryonic arrest, suggesting that mcm-5 was also required for embryonic development. After RNAi treatment of the other MCM2-7 family members, we found that they all exhibited similar phenotypes as mcm-5, suggesting that the MCM2-7 family in C. elegans might function associated with cell division as its homologues in S. cerevisiae.

Customized TALENs and Cas9/gRNAs have been used for targeted mutagenesis in zebrafish to induce indels into protein-coding genes. However, indels are usually not sufficient to disrupt the function of non-coding genes, gene clusters or regulatory sequences, whereas large genomic deletions or inversions are more desirable for this purpose. By injecting two pairs of TALEN mRNAs or two gRNAs together with Cas9 mRNA targeting distal DNA sites of the same chromosome, we obtained predictable genomic deletions or inversions with sizes ranging from several hundred bases to nearly 1 Mb. We have successfully achieved this type of modifications for 11 chromosomal loci by TALENs and 2 by Cas9/gRNAs with different combinations of gRNA pairs, including clusters of miRNA and protein-coding genes. Seven of eight TALEN-targeted lines transmitted the deletions and one transmitted the inversion through germ line. Our findings indicate that both TALENs and Cas9/gRNAs can be used as an efficient tool to engineer genomes to achieve large deletions or inversions, including fragments covering multiple genes and non-coding sequences. To facilitate the analyses and application of existing ZFN, TALEN and CRISPR/Cas data, we have updated our EENdb database to provide a chromosomal view of all reported engineered endonucleases targeting human and zebrafish genomes.

Hemorrhagic disease of the grass carp, Ctenopharyngodon idella, is a fatal disease in fingerlings and yearlings caused by a reovirus, GCRV. RNA-seq data from four diseased grass carp tissues (gill, intestine, liver and spleen) were obtained at 2h before and six times after (2h, 24h, 48h, 72h, 96h and 120h) GCRV challenge. A total of 7.25=C2=B10.18 million (M) clean reads and 3.53=C2=B10.37M unique reads were obtained per RNA-seq analysis. Compared with controls, there were 9060 unique differentially expressed genes (DEGs) in the four tissues at the six time points post-GCRV challenge. Hierarchical clustering analysis of the DEGs showed that the data from the six time points fell into three branches: 2h, 24h/48h, and 72h/96h/120h. Singular (SEA) and modular enrichment analyses of DEGs per RNA-seq dataset were performed based on gene ontology. The results showed that immune responses occurred in all four tissues, indicating that GCRV probably does not target any tissue specifically. Moreover, during the course of disease, disturbances were observed in lipid and carbohydrate metabolism in each of the organs. SEA of DEGs based on the Kyoto Encyclopedia of Genes and Genomes database was also performed, and this indicated that the complement system and cellular immunity played an important role during the course of hemorrhagic disease. The qPCR of pooled samples of duplicate challenge experiment were used to confirm our RNA-seq approach. Copyright =C2=A9 2014 Elsevier Ltd. All rights reserved.

Toll-like receptor 4 (TLR4) is critical for LPS recognition and cellular responses. It also recognizes some viral envelope proteins. Detection mostly results in the inflammation rather than specific antiviral responses. However, it's unclear in fish. In this report, a TLR4 gene (named as GrTLR4b) was cloned and characterized from rare minnow Gobiocypris rarus. The full length of GrTLR4b cDNA consists of 2766 nucleotides and encodes a polypeptide of 818 amino acids with an estimated molecular mass of 94,518 Da and a predicted isoelectric point of 8.41. The predicted amino acid sequence comprises a signal peptide, six leucine-rich repeat (LRR) motifs, one leucine-rich repeat C-terminal (LRRCT) motif, followed by a transmembrane segment of 23 amino acids, and a cytoplasmic region of 167 amino acids containing one Toll - interleukin 1 - receptor (TIR) motif. It's closely similar to the zebrafish (Danio rerio) TLR4b amino acid sequence with an identity of 77%. Quantitative RT-PCR analysis showed GrTLR4b mRNA was constitutive expression in gill, heart, intestine, kidney, liver, muscle and spleen tissues in healthy animals and up-regulated by viruses and bacteria. After being infected by grass carp reovirus or Aeromonas hydrophila, GrTLR4b expressions were up-regulated from 24 h post-injection and lasted until the fish became moribund (P < 0.05). These data implied that TLR4 signaling pathway could be activated by both viral and bacterial infection in rare minnow. (C) 2009 Elsevier Ltd. All rights reserved.
