Biotechnology is a multidisciplinary field that involves the integration of natural sciences and engineering sciences in order to achieve the application of organisms, cells, parts thereof and molecular analogues for products and services.
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research.
Gene knockdown is an experimental technique by which the expression of one or more of an organism's genes is reduced. The reduction can occur either through genetic modification or by treatment with a reagent such as a short DNA or RNA oligonucleotide that has a sequence complementary to either gene or an mRNA transcript.
Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA at first non-coding RNA molecules, typically 20–24 base pairs in length, similar to miRNA, and operating within the RNA interference (RNAi) pathway. It interferes with the expression of specific genes with complementary nucleotide sequences by degrading mRNA after transcription, preventing translation.
Phillip Allen Sharp is an American geneticist and molecular biologist who co-discovered RNA splicing. He shared the 1993 Nobel Prize in Physiology or Medicine with Richard J. Roberts for "the discovery that genes in eukaryotes are not contiguous strings but contain introns, and that the splicing of messenger RNA to delete those introns can occur in different ways, yielding different proteins from the same DNA sequence". He has been selected to receive the 2015 Othmer Gold Medal.
A biopesticide is a biological substance or organism that damages, kills, or repels organisms seen as pests. Biological pest management intervention involves predatory, parasitic, or chemical relationships.
George McDonald Church is an American geneticist, molecular engineer, chemist, serial entrepreneur, and pioneer in personal genomics and synthetic biology. He is the Robert Winthrop Professor of Genetics at Harvard Medical School, Professor of Health Sciences and Technology at Harvard University and Massachusetts Institute of Technology, and a founding member of the Wyss Institute for Biologically Inspired Engineering at Harvard. Through his Harvard lab Church has co-founded around 50 biotech companies pushing the boundaries of innovation in the world of life sciences and making his lab as a hotbed of biotech startup activity in Boston. In 2018, the Church lab at Harvard made a record by spinning off 16 biotech companies in one year. The Church lab works on research projects that are distributed in diverse areas of modern biology like developmental biology, neurobiology, info processing, medical genetics, genomics, gene therapy, diagnostics, chemistry & bioengineering, space biology & space genetics, and ecosystem. Research and technology developments at the Church lab have impacted or made direct contributions to nearly all "next-generation sequencing (NGS)" methods and companies. In 2017, Time magazine listed him in Time 100, the list of 100 most influential people in the world. In 2022, he was featured among the most influential people in biopharma by Fierce Pharma, and was listed among the top 8 famous geneticists of all time in human history. As of January 2023, Church serves as a member of the Bulletin of the Atomic Scientists' Board of Sponsors.
A short hairpin RNA or small hairpin RNA is an artificial RNA molecule with a tight hairpin turn that can be used to silence target gene expression via RNA interference (RNAi). Expression of shRNA in cells is typically accomplished by delivery of plasmids or through viral or bacterial vectors. shRNA is an advantageous mediator of RNAi in that it has a relatively low rate of degradation and turnover. However, it requires use of an expression vector, which has the potential to cause side effects in medicinal applications.
Genetically modified food controversies are disputes over the use of foods and other goods derived from genetically modified crops instead of conventional crops, and other uses of genetic engineering in food production. The disputes involve consumers, farmers, biotechnology companies, governmental regulators, non-governmental organizations, and scientists. The key areas of controversy related to genetically modified food are whether such food should be labeled, the role of government regulators, the objectivity of scientific research and publication, the effect of genetically modified crops on health and the environment, the effect on pesticide resistance, the impact of such crops for farmers, and the role of the crops in feeding the world population. In addition, products derived from GMO organisms play a role in the production of ethanol fuels and pharmaceuticals.
Quark Pharmaceuticals is a pharmaceutical company that develops RNA interference-based treatments for chronic and acute diseases.
Dharmacon Inc., now known as Dharmacon, was founded in 1995 by Stephen Scaringe as Dharmacon Research to develop and commercialize a new technology for RNA oligonucleotide synthesis. Originally, the company's focus was to develop 2'-ACE RNA technology as the standard for RNA synthesis and to advance RNA oligo-dependent applications and technologies.
This is a timeline of Australian inventions consisting of products and technology invented in Australia from pre-European-settlement in 1788 to the present. The inventions are listed in chronological order based on the date of their introduction.
RNA interference (RNAi) is a biological process in which RNA molecules are involved in sequence-specific suppression of gene expression by double-stranded RNA, through translational or transcriptional repression. Historically, RNAi was known by other names, including co-suppression, post-transcriptional gene silencing (PTGS), and quelling. The detailed study of each of these seemingly different processes elucidated that the identity of these phenomena were all actually RNAi. Andrew Fire and Craig C. Mello shared the 2006 Nobel Prize in Physiology or Medicine for their work on RNAi in the nematode worm Caenorhabditis elegans, which they published in 1998. Since the discovery of RNAi and its regulatory potentials, it has become evident that RNAi has immense potential in suppression of desired genes. RNAi is now known as precise, efficient, stable and better than antisense therapy for gene suppression. Antisense RNA produced intracellularly by an expression vector may be developed and find utility as novel therapeutic agents.
Galena Biopharma was a publicly traded pharmaceutical company based in San Ramon, California. The company was founded in Worcester, Massachusetts. In 2011, it moved to Oregon, and in 2015 moved to San Ramon, California. Mark Schwartz was the company's president and chief executive officer. As of December 29, 2017, the company was acquired by Sellas Life Sciences Group Ltd. through a reverse merger transaction. Galena Biopharma was renamed to Sellas Life Sciences Group, Inc.
DNA-directed RNA interference (ddRNAi) is a gene-silencing technique that utilizes DNA constructs to activate an animal cell's endogenous RNA interference (RNAi) pathways. DNA constructs are designed to express self-complementary double-stranded RNAs, typically short-hairpin RNAs, that bring about the silencing of a target gene or genes once processed. Any RNA, including endogenous messenger RNA (mRNAs) or viral RNAs, can be silenced by designing constructs to express double-stranded RNA complementary to the desired mRNA target.
Moderna, Inc. is a pharmaceutical and biotechnology company based in Cambridge, Massachusetts, that focuses on RNA therapeutics, primarily mRNA vaccines. These vaccines use a copy of a molecule called messenger RNA (mRNA) to carry instructions for proteins to produce an immune response. The company's name is derived from the terms "modified", "RNA", and "modern".
Alnylam Pharmaceuticals, Inc. is an American biopharmaceutical company focused on the discovery, development and commercialization of RNA interference (RNAi) therapeutics for genetically defined diseases.
