Stage-dependent expression of the chicken delta-crystallin gene in transgenic fish embryos. Marine biotechnology is also securing human health and environmental health. 2019 Aug 2;10:529. doi: 10.3389/fendo.2019.00529. A transgenic fish is a genetically modified fish whose DNA has been altered using genetic engineering techniques. Specific expression of the chicken delta-crystallin gene in the lens and the pyramidal neurons of the piriform cortex in transgenic mice. They are kept as pets or in aqua-farming for food production by modifying the expression of growth hormone. Notable examples of marine biotechnology products are Green Fluorescent Protein from jellyfish and luciferase enzyme from Vibrio fischeri, both being used in molecular biology as reporter proteins. To produce a model of transgenic fish, recombinant plasmids containing chicken delta-crystallin gene were microinjected into the oocyte nucleus of a small teleost, medaka (Oryzias latipes). The richness of marine biodiversity and genetic diversity have provided with potential biotechnological applications related to bioprospecting, drug discovery, environmental remediation, increasing seafood supply and safety, and developing new resources and industrial processes. Shiraishi E, Hosseini H, Kang DK, Kitano T, Akiyama H. PLoS One. However, many controversies have come up regarding ethical concerns, ecological concerns, and economic concerns given that GM techniques and GM organisms submit to Intellectual Property law. Studies have suggested that seaweeds could be suitable feedstocks for biorefineries.  |  Nanosecond pulsed electric field suppresses development of eyes and germ cells through blocking synthesis of retinoic acid in Medaka (Oryzias latipes). The use of the microinjection method results in higher survival rates for manipulated fish embryos than the electroporation method. To produce a model of transgenic fish, recombinant plasmids containing chicken delta-crystallin gene were microinjected into the oocyte nucleus of a small teleost, medaka (Oryzias latipes). USA.gov. The basic purpose of transgenesis in fish is to enhance their quality, growth, resistance, and productivity. Cell Differ Dev. Microinjection method:Microinjection method has been used successfully in the production of transgenic fish and is a commonly used technique due to its simplicity and reliability. Heat shock factor 1 protects germ cell proliferation during early ovarian differentiation in medaka. Kondoh H, Katoh K, Takahashi Y, Fujisawa H, Yokoyama M, Kimura S, Katsuki M, Saito M, Nomura T, Hiramoto Y, et al. This is the first report of successful production of transgenic fish. Dev Biol. Furukawa F, Hamasaki S, Hara S, Uchimura T, Shiraishi E, Osafune N, Takagi H, Yazawa T, Kamei Y, Kitano T. Sci Rep. 2019 May 6;9(1):6927. doi: 10.1038/s41598-019-43472-4. Expression and fate of CAT reporter gene microinjected into fertilized medaka (Oryzias latipes) eggs in the form of plasmid DNA, recombinant phage particles and its DNA. Involvement of Heat Shock Proteins on the Transcriptional Regulation of Corticotropin-Releasing Hormone in Medaka. Since the mid 1980 s, introduction … Cell Differ Dev. The basic purpose of transgenesis in fish is to enhance their quality, growth, resistance, and productivity. In 1 of 6 examined histologically, delta-crystallin DNA was detected in all the tissues, and delta-crystallin polypeptides, in many of the tissues including the lens. • Generally genetic modification entails manipulation of DNA . Similarly, Shrimp alkaline phosphatase and other marine-derived enzymes with heat liable properties are used in various molecular applications such as PCR.eval(ez_write_tag([[728,90],'explorebiotech_com-box-4','ezslot_18',107,'0','0'])); A transgenic fish is a genetically modified fish whose DNA has been altered using genetic engineering techniques. About 50% of the microinjected oocytes developed to 7-day-old embryos. Proteins, enzymes, biopolymers, bio-adhesives, and biomaterials are produced on a large scale from the marine ecosystem. Production of biofuel from microalgae is quite promising. Gene delivery to marine animals is one of the most significant applications of marine biotechnology. Microinjection that allows delivery of the transgene directly into the nucleus, Transgene is directly microinjected into the male pron… 1989 Sep;78(3):369-80. doi: 10.1007/BF00265299. 3. The transgenic fish contains a foreign DNA sequence that is integrated into its chromosomal DNA. Get the latest research from NIH: https://www.nih.gov/coronavirus. The colors include red, yellow, blue, green, brown, dark, purple, white, gold and grey, each resembling a particular area of biotech activities. However, a large part of coastal waters is turning unfit to sustain life forms because of human activities and pollutants. The rights to GloFish are owned by Spectrum Brands, Inc., which purchased GloFish from Yorktown Technologies, the original developer of GloFish, in May 2017. Marine-derived food products and nutraceuticals are an integral part of human nutrition in many parts of the world. The most established method for gene transfer in fish is microinjection. There have been numerous development of novel drugs, painkillers, antibiotics, anticancer drugs, and cosmetics from marine bioresources. Please enable it to take advantage of the complete set of features! On the other hand, there’s emerging development of biotechnological approaches, mechanisms, and applications to address key environmental issues such as marine-derived antifouling strategies, marine habitat restoration, bioremediation of marine ecosystems, and the use of high-resolution biosensing techniques to monitor the in situ marine environments.
