Caenorhabditis elegans Cer13 virus is a species of virus in the genus Semotivirus and the family Belpaoviridae . It exists as retrotransposons in the Caenorhabditis elegans genome.
Caenorhabditis elegans is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek caeno- (recent), rhabditis (rod-like) and Latin elegans (elegant). In 1900, Maupas initially named it Rhabditides elegans. Osche placed it in the subgenus Caenorhabditis in 1952, and in 1955, Dougherty raised Caenorhabditis to the status of genus.
Metaviridae is a family of viruses which exist as Ty3-gypsy LTR retrotransposons in a eukaryotic host's genome. They are closely related to retroviruses: members of the family Metaviridae share many genomic elements with retroviruses, including length, organization, and genes themselves. This includes genes that encode reverse transcriptase, integrase, and capsid proteins. The reverse transcriptase and integrase proteins are needed for the retrotransposon activity of the virus. In some cases, virus-like particles can be formed from capsid proteins.
Caenorhabditis is a genus of nematodes which live in bacteria-rich environments like compost piles, decaying dead animals and rotting fruit. The name comes from Greek: caeno- ; rhabditis = rod-like. In 1900, Maupas initially named the species Rhabditis elegans, Osche placed it in the subgenus Caenorhabditis in 1952, and in 1955, Dougherty raised Caenorhabditis to the status of genus.

Most animal testing involves invertebrates, especially Drosophila melanogaster, a fruit fly, and Caenorhabditis elegans, a nematode. These animals offer scientists many advantages over vertebrates, including their short life cycle, simple anatomy and the ease with which large numbers of individuals may be studied. Invertebrates are often cost-effective, as thousands of flies or nematodes can be housed in a single room.
SAND protein family, first described in Saccharomyces cerevisiae, is membrane protein related with vesicle traffic: vacuole fusion in yeasts and lysosome one motility in mammals and other taxa. In humans has been described an interaction with HSV-1, a virus which produces Herpes simplex.
DAF-16 is the sole ortholog of the FOXO family of transcription factors in the nematode Caenorhabditis elegans. It is responsible for activating genes involved in longevity, lipogenesis, heat shock survival and oxidative stress responses. It also protects C.elegans during food deprivation, causing it to transform into a hibernation - like state, known as a Dauer. DAF-16 is notable for being the primary transcription factor required for the profound lifespan extension observed upon mutation of the insulin-like receptor DAF-2. The gene has played a large role in research into longevity and the insulin signalling pathway as it is located in C. elegans, a successful ageing model organism.
In molecular biology mir-84 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
CER1 or Cer1 may refer to :
A coelomocyte is a phagocytic leukocyte that appears in the bodies of animals that have a coelom. In most, it attacks and digests invading organisms such as bacteria and viruses through encapsulation and phagocytosis, though in some animals it does not seem capable of the phagocytosis. A coelomocyte may either be fixed to the body wall or may be free-floating within the coelom.
Caenorhabditis elegans- microbe interactions are defined as any interaction that encompasses the association with microbes that temporarily or permanently live in or on the nematode C. elegans. The microbes can engage in a commensal, mutualistic or pathogenic interaction with the host. These include bacterial, viral, unicellular eukaryotic, and fungal interactions. In nature C. elegans harbours a diverse set of microbes. In contrast, C. elegans strains that are cultivated in laboratories for research purposes have lost the natural associated microbial communities and are commonly maintained on a single bacterial strain, Escherichia coli OP50. However, E. coli OP50 does not allow for reverse genetic screens because RNAi libraries have only been generated in strain HT115. This limits the ability to study bacterial effects on host phenotypes. The host microbe interactions of C. elegans are closely studied because of their orthologs in humans. Therefore, the better we understand the host interactions of C. elegans the better we can understand the host interactions within the human body.
Orsay virus is a positive-sense single-stranded RNA virus that infects Caenorhabditis elegans nematode. It resembles nodaviruses, but has yet to be formally classified.
Metavirus is a genus of viruses in the family Metaviridae. They are retrotransposons that invade a eukaryotic host genome and may only replicate once the virus has infected the host. These genetic elements exist to infect and replicate in their host genome and are derived from ancestral elements unrelated from their host. Metavirus may use several different hosts for transmission, and has been found to be transmissible through ovule and pollen of some plants.
Semotivirus is the only genus of viruses in the family Belpaoviridae. Species exist as retrotransposons in a eukaryotic host's genome. BEL/pao transposons are only found in animals.
Caenorhabditis elegans Cer1 virus is a species of retroviruses in the genus Metavirus.
Ortervirales is an order that contains all accepted species of single-stranded RNA viruses that replicate through a DNA intermediate and all accepted species of double-stranded DNA viruses that replicate through an RNA intermediate . The name is derived from the reverse of retro.
Eileen Southgate is a British biologist who mapped the complete nervous system of the roundworm Caenorhabditis elegans, together with John White, Nichol Thomson, and Sydney Brenner. The work, done largely by hand-tracing thousands of serial section electron micrographs, was the first complete nervous system map of any animal and it helped establish C. elegans as a model organism. Among other projects carried out as a laboratory assistant at the Medical Research Council Laboratory of Molecular Biology (MRC-LMB), Southgate contributed to work on solving the structure of hemoglobin with Max Perutz and John Kendrew, and investigating the causes of sickle cell disease with Vernon Ingram.
The Dod-13 gene in the worm Caenorhabditis elegans encoding a cytochrome p450 enzyme, which have steroid hydroxylase activity, with the CYP Symbol CYP35B1. Dod-13 is downstream gene of Daf-16 influenced the lifespan of C. elegans.
Cytochrome P450, family 13, also known as CYP13, is a nematoda cytochrome P450 monooxygenase family. The first gene identified in this family is the CYP13A1 from the Caenorhabditis elegans.
Cytochrome P450, family 25, also known as CYP25, is a nematoda cytochrome P450 monooxygenase family. The first gene identified in this family is the CYP25A1 from the Caenorhabditis elegans.
