  • Caenorhabditis Elegans Lab Report

    The effects of gene mutation on Olfactory Sensory Neurons in Caenorhabditis Elegans Amira Brown University of California, Santa Barbara Abstract This experiment examines the effects of distinct odorants on chemotaxis behavior of the nematode worm, Caenorhabditis elegans (C. Elegans). Nematode worms are appropriate for sensory physiology studies because its neuronal wiring is similar to that of humans. We focused on the role of three sensory neurons in the nose of the nematode—the 1) AWA and 2) AWC neurons are involved in chemo-attraction and the 3) AWB neurons are involved in repulsion. With the use of RNA interference (RNAi), we diminished or eliminateed specialized proteins within the worms to test if their olfactory…

  • Caenorhabditis Elegans

    1.1 Caenorhabditis elegans (C. elegans) Caenorhabditis elegans is a free-living non-parasitic, non-infectious, non-pathogenic, transparent Nematode (roundworm). It has a full grown length of about 1mm, a life span of around 3 weeks and is found in temperate soil environments where it survives by feeding on microbes such as bacteria. [1] Consisting of about 1000 somatic cells as an adult, C. elegans is amenable to genetic crosses and produces a large number of progeny, at times even…

  • Caenorhabditis Elegans: Bag Of Worms

    One great organism to study is Caenorhabditis elegans (C.elegans ) because it is hermaphrodites, transparents and small enough to observe under the microscope. After adding mutagens to them, scientists can get all kinds of freak worms after few days. “Bag of worms” are one of them. It can not lay eggs so its body occupied with dozens of eggs. When eggs hatched inside the worm, larvae eat the mother worm and them come out. Ambros, a scientists who just finished doctor degree at MIT, first…

  • Mitophagy Lab Report

    Sensitivity of Cancerous C.elegans with Mitochondria Dysfunction Mitophagy is a selective autophagic elimination of damaged or excessive mitochondria, especially when cells are under adverse stress. Mitophagy has been identified as the cause of various human diseases and even cancer. In recent years, researchers gradually regard mitophagy as the target for cancer treatment, although the role of mitophagy in the developmental and metabolic process of cancer is still not clear. In this…

  • C. Elegans

    In 1963, the South African biologist Sydney Brenner proposed C. elegans as a model system for studies of development and neurobiology. Researchers share their findings in C. elegans genome via the internet with other researchers from around the world. The process of sharing the genome database on the world wide web provides a working framework for researchers who are working on the human genome project In 1969, John Sulston developed a technique to freeze and thaw the worm. As a result, the…

  • Importance Of Brain To Brain Communication

    Science, there are 376 essays related with FMRI in which problems about drug action, individual brain maturity and many other topic are solved. Besides, FMRI can be combined and complemented with other measures of brain physiology such as Electroencephalography and Near-infrared spectroscopy (Ilmoniemi), which means FMRI can be an important part of the huge scanning system of brain cooperating with other parts. Transferring data to brain accurately used to be difficult to realize, but now it…

  • GFP Variants

    victoria’s GFP in prokaryotic Escherichia coli and eukaryotic Caenorhabditis elegans cells. The E. coli cells transformed to express the gfp gene, fluoresced green as opposed to the control bacteria. They also showed that GFP had no apparent negative side effect on the living cells as the media contained the inducer IPTG. This was an indication that GFP wold be a great candidate for observing gene expression and subcellular localization of proteins. GFP’s may also be used for identification of…

  • Age-Related Diseases: A Case Study

    Cynthia Kenyon’s plan to reverse aging in humans and stimulate genes that cause age related diseases, was the medical advancement that I was able to research and determine according to my ethics whether or not or not I would support this experiment. A big breakthrough for Kenyon, was when she found out that there was a universal hormonal control for aging in Caenorhabditis elegans, in other words, small roundworms. This hormonal control gene, daf-2, activates receptors that are sensitive to two…

  • Apterous Gene Mutation

    The ap gene is a new member of the LIM family of developmental regulatory proteins that is characterized by the presence of LIM domain and homeo domain. The ap protein shows an amino acid sequence similar to the lin-11 and mec-3 proteins of Caenorhabditis elegans. Ap function is required for normal wing and haltere disc development in fruit flies during the third larval instar. The mutations in recessive flies are consistent with ap expression patterns in the larval imaginal discs. Ap regulates…

  • Pseudomonas Aeruginosa Research Paper

    aeruginosa wound infections occur most often in the hospital from surgical wound treatment and are known to be the leading cause of burn infections (Nedeljković, Tiodorović, Kocić, Cirić, Milojković, and Waisi 2015). This pathogen also has the ability to infect plants and non-mammalians. Certain strains of this organism are capable of infecting plants such as Arabidopsis, and sweet basil. The strains PAO1 and PA14 are known to infect the roots of these plants and can be fatal to the plants .The…
