Pathogen Response Genes Mediate Caenorhabditis elegans Innate Immunity

, 2012
Innate immunity is crucial in the response and defense against pathogens for invertebrates and vertebrates alike. The soil nematode Caenorhabditis elegans is a useful model to study the eukaryotic innate immune response to microbial pathogenesis.

Argonaute Proteins Affect siRNA Levels and Accumulation of a Novel Extrachromosomal DNA from the Dictyostelium Retrotransposon DIRS-1*

Journal of Biological Chemistry, 2014
Background: Retroelements are frequently under stringent control by RNAi mechanisms. Results: Disruption of the Argonaut AgnA in Dictyostelium leads to loss of retroelement siRNAs, retroelement-encoded proteins, and accumulation of a cytoplasmic cDNA ...

Single/low-copy integration of transgenes in Caenorhabditis elegans using an ultraviolet trimethylpsoralen method

BMC Biotechnology, 2012
Background Transgenic strains of Caenorhabditis elegans are typically generated by injecting DNA into the germline to form multi-copy extrachromosomal arrays. These transgenes are semi-stable and their expression is silenced in the germline.

Tandemly repeated C-C-C-C-A-A hexanucleotide of Tetrahymena rDNA is present elsewhere in the genome and may be related to the alteration of the somatic genome. [PDF]

, 1981
The ribosomal RNA genes of the Tetrahymena macronucleus exist as extrachromosomal, linear molecules. The termini of these molecules have been shown to contain the tandemly repeated hexanucleotide (C-C-C-C-A-A)n.

A Small Family of Elements with Long Inverted Repeats is Located Near Sites of Developmentally Regulated DNA Rearrangement in \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

, 1994
Extensive DNA rearrangement occurs during the development of the somatic macronucleus from the germ line micronucleus in ciliated protozoans. The micronuclear junctions and the macronuclear product of a developmentally regulated DNA rearrangement in ...

Transformation of \u3cem\u3eTetrahymena thermophila\u3c/em\u3e with Hypermethylated rRNA Genes [PDF]

, 1988
The extrachromosomal rRNA genes (rDNA) of Tetrahymena thermophila contain 0.4% N6-methyladenine. C3 strain rDNA was isolated, hypermethylated in vitro, and microinjected into B strain host cells. Clonal cell lines were established, and transformants were
